iPhone SE

iPhone SE is the perfect copy of the iPhone 5s in appearance. But the battery of the iPhone SE has a higher capacity than that of the “big brother”. The difference is not significant, but the battery life of the iPhone SE is still better compared to the iPhone 5s.

Battery: Built-in 1624mAh Li-ion battery.

iPhone 5s

The former flagship Apple iPhone 5s includes a very capacious battery. Add to this the excellent work of Apple engineers to optimize the use of resources by the mobile operating system iOS and get from 8 to 250 hours of battery life.

Battery: Built-in 1560mAh Li-ion battery

iPhone XS Max

The huge 6.5-inch iPhone XS Max has set several records at once. The smartphone not only received the largest display in the entire history of Apple smartphones, but also the most capacious battery. Thanks to the significantly increased battery capacity, the iPhone XS Max can last a full 1.5 hours longer than the iPhone X or 25 hours of talk time.

Battery: Built-in 3174mAh Li-ion battery.

Which iPhone holds the battery better? Comparison of battery life of all current iPhones in 2020

Apple never mentions battery capacity in product descriptions for marketing reasons. Instead, on the company’s website, you can read how long the iPhone can work in one mode or another and compare the indicators with other models.

iPhone 11 Pro

The battery capacity of the iPhone 11 Pro has been significantly increased over the previous 5.8-inch iPhone X and iPhone XS models. The increase in capacity directly affected the battery life of the smartphone. It increased immediately by four (!) Hours compared to the iPhone XS. The most powerful improvement that made the iPhone 11 Pro one of the longest-lived flagship smartphones.

Battery: Built-in 3046mAh Li-ion battery.

iPhone 6

Finally, we got to the “big” Apple smartphones, which have everything in perfect order with the batteries. Users who are not even fans of the iPhone, note on the Web how long “sixes” work without recharging. “To blame” for this:

Battery: Built-in 1810mAh Li-ion battery

Charge iPhone from a computer using a USB cable

Another answer is how to charge an iPhone. plug the cable into the USB port of the computer. But first, it is advisable to figure out what USB ports your computer has.

Today they are equipped with three types: USB 1.0, 2.0 or 3.0. The first and second are capable of providing 500 mA (2.5 W), while USB 3.0 is almost twice as much. up to 900 mA (5 W).

Depending on the type of USB the phone is connected to, charging times can vary greatly. Accordingly, the iPhone takes a long time to charge from USB 1.0, from USB 3.0 it is almost twice as fast. Distinguishing USB 3.0 from USB 1.0, 2.0 is simple:

How to charge iPhone and what kind of chargers you can use

With the increase in the number of gadgets, the number of chargers increases. And if earlier only its own cable was suitable for almost every device, now many manufacturers have taken the path of unification, that is, charging has a USB output, and which cable to connect with which device is already the user’s choice. So the question arises: is it possible to take one charger and charge the iPhone, iPad, etc. without harm to the battery?

First, a little theory about the battery

IPhone / iPod / iPad contains lithium-ion polymer batteries.

Lithium-ion batteries provide longer battery life with less weight because lithium is the lightest metal. In addition, lithium-ion batteries can be charged at any time without having to wait until they are completely discharged, as was the case with the first mobile phones with nickel batteries.

In day-to-day use, keeping a lithium battery in good condition requires that the electrons in it be periodically in motion. To do this and to calibrate the battery indicator, it is necessary to carry out at least one recharging cycle per month (fully charging and then discharging the battery).

How to charge iPhone with chargers

At the output, they provide different amperage.

Native iPhone chargers, Europe and Asia. At the exit they give. 5W (5V. 1A).

Chinese universal for travelers :. 2.5W (5V. 0.5A).

Universal charging from an e-book (the manufacturer recommends using only it in the instructions). 5W (5V. 1A).

Battery for emergency recharging of the device in the absence of an electrical network. 5W (5V. 1A).

Remembering the course of school physics, I can make the statement that the stronger the charging current, the shorter the battery life. By the way, lithium batteries are much more sensitive to excessive charging currents than nickel ones, and the faster the battery is charged, the fewer operating cycles it will have before the working capacity begins to decrease. It follows from this logic that you should not charge the iPhone with a charger from the iPad.

However, Apple’s website says that using a “native” USB cable and any iPad charger, you can charge your iPhone. source.

The table also lists all power adapters and talks about the ability to connect the iPhone to an adapter that produces a higher current.

Charging with a lower current simply extends the charging time of the device.

It would seem, why is Apple not important about the strength of the incoming current into the device? Everything is very simple, the iPhone has a separate charge controller that regulates the charge current, so nothing terrible should happen.

Summarizing all of the above, for myself I made the following conclusion

It is better to use a different adapter for each device.

For iPhone, this is 1 amp adapter included. although if there is no time and you need to quickly recharge the device, you can use it from the iPad, though I personally am confused by the heating of the cable at the place of docking with the phone.

IPhone Standard Tools

IOS 12 introduces a new feature in testing that allows you to see the current state of the battery.

  • Go to “Battery Status”.
  • In the menu that opens, you will see the “Maximum capacity” column, which indicates the state of the phone’s battery. In case you see a reading of 100%, the battery has the maximum capacity. Over time, this indicator will decline. For example, in our example, it is 81%. this means that over time the capacity has decreased by 19%, therefore, the device has to be charged a little more often. If this indicator drops to 60% and below, it is strongly recommended to replace the phone battery.
  • Checking iPhone battery wear

    To make your smartphone battery last longer, you need to follow simple guidelines that will significantly reduce wear and tear and extend the lifespan. And to find out how rationally to use the old battery in the iPhone, there are two ways: using standard iPhone tools or using a computer program.


    IBackupBot is a special iTunes add-on that allows you to manage iPhone files. Of the additional capabilities of this tool, the section for viewing the status of the iPhone battery should be noted.

    Please note that iTunes must be installed on your computer for iBackupBot to work.

    • Download the iBackupBot program from the developer’s official website and install it on your computer.
    • Connect iPhone to computer with USB cable and then launch iBackupBot. The smartphone menu will be displayed in the left part of the window, in which you should select the “iPhone” item. A window with information about the phone will appear on the right. To get information about the battery status, click on the “Information” button.
  • A new window will appear on the screen, in the upper part of which we are interested in the “Battery” block. It contains the following indicators:
  • CycleCount. This indicator means the number of complete charging cycles of the smartphone;
  • DesignCapacity. Initial battery capacity;
  • FullChargeCapacity. Actual battery capacity based on wear.
  • Thus, if the indicators “DesignCapacity” and “FullChargeCapacity” are close in value, the smartphone’s battery is normal. But if these numbers are very different, you should think about replacing the battery with a new one.

    Any of the two methods given in the article will give you comprehensive information about the condition of your battery.

    How to calibrate iPhone battery and why you need it?

    Hello everyone! The iPhone has a lithium-ion battery, and these batteries are not known to have a memory effect. Then why calibrate them at all? The fact is that the capacity of the battery drops over time (how to check its current state) and if you have had the phone for a long time, then in the absence of battery calibration, strange things begin

    It happens that the iPhone “does not understand” what the current battery capacity is and cannot correctly display information about the battery charge level. As a result, various non-standard situations occur: an unexpected shutdown by 20-30%, freezing of the charging indicator (long display of one value), incorrect data is shown about how charged the iPhone is and other disgrace.

    By the way, although in this article I write everywhere about the iPhone, this method of battery calibration is great for other Apple equipment: iPad and iPod.

    But first, let’s summarize the signs that clearly indicate that the iPhone battery needs to be calibrated.

    • iPhone shuts down when there is still charge percentage. It would seem that he still has to work and work, but he bam and turned off.
    • In some cases, calibration will help those users who run out of battery very quickly. True, this is just one of the methods of dealing with an instantly discharging smartphone.
    • If the iPhone freezes for a long time at one percent of the charge, and then the indicator sharply “jumps” by several tens of percent.
    • It is advisable to perform calibration every 2-3 months for absolutely all iPhone and iPad users. If you’ve never done it, now is the time!

    At least one of the described cases is your situation?

    Then read on and learn how to properly calibrate the iPhone battery.!

    • Wait until the device is completely discharged. It is entirely and completely (absolutely, “to zero”, so that it is not included at all).
    • We put it on charge (preferably from the network) and do not touch it (of course, you can answer an urgent call, but you do not need to play and use). We wait until it is charged to 100%.
    • We leave connected for another hour or two. What for? For reliability! After all, the iPhone does not show charging correctly? Wrong! So, you can’t trust him. And despite the fact that the screen displays 100% charge, the battery may not be fully charged! Therefore, to be sure, after reaching 100%, we do not turn off the plug immediately, but wait at least another hour.
    • Disconnect from the network and do a hard reboot. To do this, press and hold two keys. Home and Power on, until the apple icon lights up on the screen. Updated! This combination of buttons does not work for all devices. How to be? Here is a detailed instruction on how to Hard Reset any iPhone.!
    • We use the device until it is completely discharged.
    • We repeat this procedure 2-3 times.

    As you can see, there is nothing super complicated. And the only “narrow” moment is time.

    But there’s nothing you can do about it, battery calibration is not a quick thing.

    Important! When you start doing the second loop, you do not need to recharge your iPhone for a short time! The circuit should be exactly like this. from 100% to 0%, then to full charge without interruption, charged, hard reset and discharged to 0% without recharging.

    Only then will the calibration be truly correct and will benefit your iPhone’s battery.

    Apple never discloses the amount of RAM and battery capacity of the iPhone, noting only performance and battery life improvements over the previous model. But when choosing a new smartphone, I want to get information about all its characteristics, including the battery capacity.

    How to find out the battery capacity using the AIDA64 program

    If you already use an iPhone and want to see the capacity of its battery, you will need to install a benchmark or other special application on your smartphone that can determine the characteristics of the device. Let’s use the AIDA64 program as an example. Download it from the App Store, run it and go to the “Battery” section. There, in the “Capacity” line, the battery capacity of your iPhone will be displayed.

    Battery Calibration. Why You Need It?

    Even if you know how to properly handle the iPhone, you will not be able to charge it according to all the rules day after day. This is usually done haphazardly and anywhere. Plus other errors in operation, plus natural aging of the battery, accompanied by a decrease in capacity, plus chemical processes in the batteries. all this leads to the fact that over time the power controller stops accurately determining the charge level.

    In order for the gadget to correctly display this indicator, you need to calibrate the battery from time to time. Namely: fully charge the iPhone and then discharge it to zero.

    This procedure will bring the controller to life, and the battery level indicator will show the correct numbers again.

    Calibration should not be done too often. Apple recommends that you completely discharge your iPhone no more than once a month.

    Do not bring your battery to zero

    Ideally, it is best to charge the iPhone at 10-20% battery and unplug it from the charger at 80-90%. The explanation is simple. The life of a lithium-ion battery is measured by the number of full discharge cycles. IPhone battery life is approximately 500 cycles. That is, to completely kill the battery, it is enough to discharge it to complete zero 500 times. Therefore, the more often a deep discharge occurs, the sooner it will fail.

    It is believed that a 100% charge, although not so terrible, is also undesirable. Because, although the controller will not let the battery overheat, the constant connection to the power source, although slowly, still reduces its capacity. This statement is rather controversial, because the battery, having typed 100%, stops charging automatically and will not take too much. Many experts, on the contrary, believe that it is best to leave the iPhone on recharging overnight. to give the gadget time to update all the necessary applications.

    The sun is the enemy of the battery

    Apple guidelines say the ideal temperature for using and charging an iPhone is between 16 ° C and 20 ° C. The temperature is really comfortable (and not only for gadgets), but the iPhone is not such a delicate device, and it does not need such greenhouse conditions. Many specialized sites and blogs warn against extreme temperatures from minus 40 to plus 50, which are not very typical for the lifestyle of the average Russian owner of an expensive device. Putting together Apple’s instructions and numerous opinions of experienced users, we can say that overheating is not so terrible (temperatures up to 35 degrees are generally not critical) as direct sunlight.

    Even with mild heat, this can, if not kill the battery, then certainly sharply reduce its capacity.

    By the way, the battery tolerates subzero temperatures better than heat. After warming up, the battery restores its functions, although, of course, it is not worth freezing it either.

    iPhone Mothballed: How to Conserve Battery Capacity

    There are situations when the iPhone is not used for a long time. In this case, every 6 months it must be charged up to 50%. If you leave an unused gadget with a fully charged battery for a long time, it will lose some of its capacity. If you mothball a completely discharged iPhone, the battery will go into deep discharge, which is even worse. Therefore, store the device in the off state, in a dry room and with a half-charged battery.

    Basic rules for proper charging

    There are elementary rules for competent and most gentle battery charging. There are few of them:

    • Do not charge iPhone in extreme temperatures;
    • Use the original (native) charger;
    • Try not to discharge the gadget completely, to 0% (here, however, there is one subtlety, but more about it below);
    • Do not charge the battery to 100%

    Apple’s step-by-step charging instructions are also simple:

    • Use a cable and power adapter to connect iPhone to a power outlet.
    • If you are using a wireless MagSafe device, place the gadget on the device with the screen facing up. It is important to put it correctly, then the charging will be faster. Qi chargers can also be used.
    • When charging from a computer, it is important to ensure that it has the correct USB port and that the computer is turned on. Because if you connect your iPhone to a turned off PC, the battery of the gadget may even start to discharge.
    • If an image of a discharged battery appears on the screen, you need to put the iPhone on recharging for at least 10 minutes;
    • IPhone cannot be charged if water gets into the connector.
    • Finally, you cannot change the battery yourself. This can only be done by the manufacturer or an authorized service provider.

    The video below also provides helpful tips on how to charge your iPhone without damaging the battery:

    Use original adapters and cables

    Naturally, it’s best to use the charger you bought with your iPhone. But it happens that the charger is lost and then low-quality fakes are often replaced. Their danger is that the adapter must have the required voltage and current parameters, and if the voltage is exceeded by at least 3-4%, the battery will begin to die about twice as fast. To prevent this from happening, the original adapters have a built-in PCIM controller, which is usually not found in fakes. It’s the same with the Lightning cable. The original product is equipped with a chip, which is required, for example, for authentication. It is quite difficult to fake it, but in China they even managed to do this. Penny Chinese cables with a fake chip also work, but usually not for long.

    So there is only one way out. to buy accessories from manufacturers authorized by Apple. They are usually marked with the letters MFI (Made For iPhone).

    Another question: can a smartphone be charged via an iPad charger? The answer is unequivocal: yes, you can. provided that the adapter is original. The device for the iPad gives out a slightly higher current (2.1 A), but, thanks to the built-in controller, the battery does not overload.

    Tips on how to properly charge your iPhone to avoid damaging your battery

    As you know, the first herald of the imminent failure of the iPhone is the battery. At first, it lasts less and less time, then the owner tries to replace it, and often without much success. So it is better to use the “native” battery as long as possible than to look for a new one.

    Optimized or smart charging

    Basically, the charging rules are the same for all Apple smartphone models. Differences. in new features that are supported in iPhones with iOS 13 operating system, for example, iPhone 11.

    It’s not even about a more capacious battery, which holds a charge for about an hour, or even one and a half longer than batteries in devices of earlier generations. The 11th model has an “optimized charging” function that will help keep the battery “like new” for a long time.

    It works like this. A device with artificial intelligence, as it were, studies the lifestyle of its owner in order to independently find the optimal time and intensity of current supply.

    For example, knowing when the owner puts it on charge in the evening and what time he disconnects it from the power supply in the morning, it will quickly gain 80% within an hour and a half and stop in standby mode.

    You can enable the function in the settings. In the “battery” section, you need to find the “battery status” and select the “optimized charging” option.

    In summary, there are no very strict rules about how you charge your iPhone. There are only recommendations, following which you can significantly extend the life of the gadget. In addition, a power controller is already built into it, which plays the role of a kind of protection against a fool, so that even with the most barbaric handling of the device, nothing terrible will happen to it. Unless you have to change in a year and a half, and not in three or four.

    iPhone XR: battery specifications

    Apple has puzzled users and installed a battery on the 10th version of the iPhone, which is more powerful than the others in the line (except for the XS Max). We offer a comparative table (the data declared by the manufacturer are shown).

    Apple iPhone XR Apple iPhone X Apple iPhone XS Apple iPhone XS Max
    Battery capacity 2,942 mAh 2 716 mAh 2 658 mAh 3,174 mAh
    Talk time 1 day, 1 h. 21 h. 20 h. 1 day, 1 h.
    Web surfing time (LTE) 15 h. 12 h. 12 h. 13 h.
    Video playback time 16 h. 13 h. 14 h. 15 h.
    Audio playback time 2 days, 17 h. 2 days, 12 hours. 2 days, 12 hours. 2 days, 17 h.

    An interesting situation turns out. Firstly, the iPhone XR is second only to the top smartphone in the line-up, the XS Max, in terms of battery capacity. Secondly. although the capacity of a milliamp in the iPhone XR battery is less than that of the most expensive smartphone in the lineup, it still surpasses it in terms of autonomy.

    There is no secret here. The “budget” iPhone model XR has a screen diagonal of 6.1 inches, and the maximum version. 6.5. The main energy consumption goes to the display, the larger it is, the faster the battery runs out.

    Features, volume and battery capacity of the iPhone XR

    Everyone chooses an iPhone for personal tasks. For some, the most important criterion is a camera with two lenses and a telezoom, for others. the function of shooting 4K video. Some pay attention to design, others to performance. However, battery capacity and battery life are important to everyone. Find out how much mAh is in the iPhone XR and how long it can stay on a single charge.

    A moment of objectivity

    It’s impossible to predict exactly how long an iPhone will last without recharging. Someone. three days, someone. only until the end of the working day. The main criterion here is the intensity of use of the gadget from Apple. Therefore, all the above values ​​can be considered averaged, they do not necessarily coincide with reality.

    Difficulties in translating the battery capacity of the iPhone

    The way Apple presents its smartphones has already become a meme among the users of this brand. In particular, the description of the batteries that will appear in the new iPhones evokes a smile. For example, we are told that the new product will work “for an hour and a half longer than the previous iPhone.” At the same time, avoiding any specifics. In addition, Apple uses the obscure term “mach”.

    Due to the fact that China is very strict about the certification of foreign high-tech products, Apple was forced to disclose full information about the iPhone even before the start of sales. Thanks to the Chinese that at last the buyers got a chance to find out the “stuffing” of the iPhone in advance. By the way, it is thanks to the battery capacity of the XR that many buyers have made a choice in its favor.

    The previous table compares the iPhone XR with the rest of the tenth series smartphones. Below we suggest using Apple’s terminology and imagine how many minutes or hours the new product is more autonomous than previous models. The average value of conversation, audio and video playback, web surfing was taken.

    IPhone Model Actual capacity Capacity according to Apple
    iPhone XS Max 3174 mAh 1.5 hours from iPhone X
    iPhone XS 2658 mAh 0.5 hours from iPhone X
    iPhone XR 2942 mAh 1.5 hours from iPhone 8 Plus
    iPhone X 2716 mAh 2 hours from iPhone 7
    iPhone 8 Plus 2675 mAh Same as iPhone 7 Plus
    iPhone 8 1821 mAh Like the iPhone 7
    iPhone 7 Plus 2900 mAh 1 hour from iPhone 6s Plus
    iPhone 7 1960 mAh 2 hours from iPhone 6s
    iPhone 6s Plus 2750 mAh
    iPhone 6s 1715 mAh

    Every new iPhone becomes more autonomous despite the increase in screen size. The main reason is that each new generation of A-series processors is becoming not only more efficient, but also less energy-intensive. iPhones work on a single charge longer and longer and at the same time “faster” old counterparts.

    All gadget manufacturers strive to reduce energy costs, iPhones and Apple, in particular, are not alone here. You can cite data for 2016 and 2017 (there are no statistics for 2018).

    Flagships of 2016. Average battery life. 7 hours.

    Flagships of 2017. Average battery life. 8 hours.

    It turns out that every year gadgets, on average, add one hour to autonomy.

    How to Extend iPhone Battery Life

    Despite the fairly large battery capacity of the iPhone XR and other Apple products, it may not be enough with active use. There are several ways to extend your battery life. Let’s make a reservation right away that buying an external battery is not considered.

    • Use power saving mode. A simple and efficient way that is available on iOS 9 and above. iPhone XR itself will offer to enable this mode when the charge drops to 20% and turn off at 80%.
    • Disable LTE and Wi-Fi. Mobile Internet consumes battery power noticeably, and therefore in emergency situations you can refuse it.
    • Disable auto brightness. To extend the operating time. set the lowest possible brightness, at which it will be more or less comfortable to read. The screen is the main consumer of energy resources in the iPhone.
    • Disable push notifications. Alternatively, you can leave only the most important ones, which you cannot do without.
    • Do not use background app refresh. It is also recommended to close all programs that you can do without and that are now hanging in the background.
    • Remove dynamic wallpaper. In this case, beauty will definitely not justify the sacrifices.
    • Avoid hypothermia or overheating. Sudden temperature changes have a negative effect on the phone. If you’re out in the cold, keep your smartphone in your During the heat. in the coolest place.

    And the last piece of advice. Carry a “charger” with you if you are afraid that the charge may not be enough.

    What will happen to the iPhone 7 battery in 4 years

    What will happen next? For comparison. the iPhone 7, which is almost 4 years old. The battery has lost only a fifth of its capacity.

    What will happen to the iPhone 11 Pro Max battery in 5 months

    My 2019 iPhone 11 Pro Max shows 99 percent battery capacity almost 5 months after purchase. Apple does not cap phone power yet: “Your battery is currently maintaining normal peak performance.”.

    What will happen to the iPhone 7 battery in 4 months

    And here is the percentage of capacity left on the iPhone 7, which was purchased in November 2019. It is slightly smaller, but the smartphone is still able to work without any restrictions.

    How to turn off iPhone battery performance management

    When the battery reaches 80% and below, performance problems may begin due to the fact that the smartphone will forcibly cut down on the processor’s power in order to minimize voltage surges and not provoke spontaneous reboots. You will also see another message at the bottom of the screen that warns that your iPhone’s battery is “significantly low.” There will be another link that will point you to a page on how to service your phone.

    If your device shuts down due to low battery, the same screen will indicate that “performance management has been applied”. It will also be possible to disable this feature. Please note that you cannot turn performance management back on until the next time you turn off your smartphone. Your iPhone will automatically turn it on if it ever does. The performance management function is only available on iPhones starting from the 6s model, and therefore it is useless to search for it on earlier devices.

    Why older iPhones are slower?

    Why did we get such a menu at all? Apple said it had no goal of forcing customers to purchase a new model. It’s just that over time, lithium-ion batteries gradually lose the ability to store energy and work in low temperatures, which, in turn, can lead to spontaneous shutdown of the smartphone to protect the hardware. The feature is actually useful, but Apple hasn’t offered any alternative before, and many iPhone owners have suffered from it. In a sense, it was “foolproof”. so that the user does not overload his iPhone if the battery is already running on its last legs (the old people will remember how it ended for the Galaxy Note 7).

    IPhone X Battery Health. 3 Years After Purchase

    But what will happen if you don’t let go of the iPhone at all. If you add to this Smart Battery Case, the battery would have to be changed already.

    As you can see, the capacity of the battery may decrease unevenly. That is, it may well fall to 98% a week after the purchase, hold at this level for a while, and then decline to 94%. It all depends on the factors below. If you use only original chargers and use your smartphone in normal mode, there should be no problems, and the battery capacity will decrease more or less evenly. For example, in one year, 5% of the capacity will “go away”, in the second year. another 10%. And this is the norm.

    What is iPhone battery health

    iOS 11.3 and later have a Battery Status menu. Just go to Settings Battery Battery Status. Here you will see information about your iPhone’s maximum capacity as a percentage and peak performance. You can also see if your iPhone is slowing down due to Apple’s performance management feature.

    Loss of battery capacity even one week after purchase. this is normal. The main thing is that it does not reach 80%.

    Wasted time. Battery performance unchanged

    The program shows changes, but they are not really there

    Before starting the procedure, I recorded the values ​​in coconutBattery: the battery state is about 83%, the maximum capacity is 1631 out of 1960 mAh.

    After the procedure, the numbers in the application really increased: the state of the battery is about 88%, the maximum capacity is 1724 out of 1960 mAh.

    It would seem that it’s time to clap your hands and run to write the most positive conclusions.

    But instead, I began to observe the data that coconutBattery produces for a couple of minutes.

    The miracle app surprised me: the battery health percentages jumped by different values ​​in the range of 80-90%. Therefore, there can be no question of any accuracy in this case.

    Instead, I will use a more realistic source of information that can be trusted. “Battery Status” from the “Settings” “Battery” menu:

    And it was, and there are 87%.

    The maximum battery capacity is 87%, it was the same before the experiment and remained the same after it.

    This confirms two facts:

    ▪️ There is no point in calibrating the iPhone battery. we’ll see this a couple of times later. ▪️ Third-party apps do not have access to real iPhone battery data.

    If you are not satisfied with the battery life of your iPhone, and the number of its recharge cycles has exceeded 500, replace the battery

    Humble yourself, this is a consumable, and it gradually breaks down every second.

    When to Change Your Favorite iPhone Battery

    500 cycles is not always the limit

    Apple recommends changing the battery after 500 charge cycles. During this time, his condition usually falls below 80%, and then the rate of his degradation grows exponentially.

    How I Maintain 100% iPhone Battery Health

    But I have in my hands a vivid example of a relatively careful attitude to the device: iPhone 7 with 750 charge cycles and 87% battery status.

    I do not do anything supernatural, but I hardly break the 5 rules above.

    tips to make your iPhone battery last longer

    Updating iOS isn’t scary today

    ? Update your iOS sooner. A couple of years ago, Apple was accused of deliberately slowing down the iPhone using new versions of the operating system.

    After that, the company is attentive to updates and regularly optimizes each subsequent.

    iPhone can and should be updated. It is best to turn on “Auto-update” in the “Settings” “General” “Software update”.

    ? Normal accessories. Cables and power supplies of unknown origin are contraindicated for long battery life.

    At the same time, to charge your iPhone, you can safely use the power supply not only from the iPad, but even from the MacBook (we are talking about USB-C).

    High and low temperatures are your enemy

    ? Be afraid of the temperature. iPhone is best charged and used in temperatures between 0 ° C and 35 ° C.

    Any stress load in conditions that go beyond these limits can be harmful to the battery.

    ? Charge without a case. Many models of cases (especially non-names) contribute to overheating of the battery.

    If you notice that iPhone is getting hot while charging, remove the case first.

    ? Store your iPhone properly. If you do not use your iPhone for a long time, keep the energy in its battery at about 50%.

    It is best to check its level once every couple of months.

    IPhone battery controllers keep track of them securely

    How the controller controls iPhone charging

    iPhone has excellent control over the charging of its battery, which takes place in two stages: charging in fast mode and trickle charge mode.

    ▪️ Charging in fast mode. First, the iPhone loads its battery as much as possible and brings the energy inside it to 80%.

    Charging times vary depending on the power source you are using: Standard PSU, iPad PSU, Power Delivery Mode with MacBook PSU and Lightning to USB-C Cable.

    At the same time, the controller monitors the temperature and reduces the charging speed if it reaches critical values.

    ▪️ Trickle charge mode. The remaining 20% ​​of the battery is charged at reduced amperage, and the energy level inside it reaches 100% gradually.

    This is necessary so that the battery is worn out as little as possible. Therefore, even my iPhone 7 with 750 recharge cycles today feels quite normal and even shows “Peak Performance” of the battery.

    Testing the most popular battery revitalization tip

    Experts recommend two steps to calibrate the iPhone battery: a preparatory step and a calibration step.

    First you need to disable resource-intensive tasks

    ️ Preparatory stage. At the preparatory stage, you should disable the most energy-consuming processes on the iPhone. This must be done so that the smartphone does not turn off by 10-20% of the charge, and we managed to discharge it to zero.

    First you need to disable automatic content downloads in the “Settings” menu “iTunes Store and App Store”.

    Next, turn off the background content update in the “Settings” “General” “Content update”.

    After that, you need to turn off geolocation in the “Settings” “Privacy” “Geolocation Services”.

    In the end, it is best to lower the brightness of the iPhone screen to the minimum value.

    A smartphone with a stale battery can turn itself off if there is not enough power, so it is better not to overload it.

    The easiest way to drain your iPhone is with movies

    ️ Calibration phase. At the calibration stage, the iPhone needs to be discharged to full zero and recharged to the maximum level at least a couple of times. For reliability, I did it 3 times.

    ▪️ To discharge the device to zero, the easiest way is to set the video to repeat in VLC and wait until the smartphone turns off.

    After that, it is better to wait a couple more hours for the internal processes to discharge the iPhone to zero. I left the device with the video overnight.

    ▪️ To charge the device for real 100%, you need to connect it to the power supply, wait for the cherished hundred to appear on the indicator, and then wait another couple of hours.

    As with discharging, I left the iPhone on charge overnight so that it could be fully charged.

    I repeated the charging and discharging procedure exactly three times: I completely discharged it during the first night, charged it for the second, and so on.

    To show the result, experts usually use the data of the coconutBattery application.

    Apple doesn’t even recommend calibration itself.

    Battery controllers are calibrated during production

    In the past, Apple actually advised to periodically calibrate the batteries of its devices. Most likely, this concept has remained in the minds of experts since then.

    However, this never had anything to do with the iPhone. Device controllers with built-in battery are calibrated during production and do not need any additional manipulations.

    Only devices with a removable battery need to be calibrated: MacBook and MacBook Pro prior to 2009, and iBook and PowerBook.
