Everyone knows that the Apple iPhone battery drains over time, and after a certain period of time it no longer produces as much energy as at the beginning. As a result, battery life is reduced and performance drops.

The fact is that the iPhone's lithium-ion battery eventually ceases to correctly see the battery level and it happens that at a charge level of 30-20%, the battery charge suddenly drops sharply and the smartphone turns off. This is alarming for many users and they do not know what to do in this case.

This is because your iPhone battery is not calibrated. Rather, the controller on the battery without calibration starts to falter. The controller performs the function of managing the battery, monitoring the boundary indicators of charging and discharging. Working malfunctioning on a small capacity, it turns off the charging of the iPhone ahead of time and, as a rule, undercharges it. So the battery needs to be calibrated.

Knowing how to calibrate the battery on an iPhone , you will not only extend the life of the battery, but get rid of the consequences of improper battery operation. This often happens when the firmware on the iPhone is updated.

The principle of calibration is that the built-in battery controller is reset to its original state. Accordingly, the cured controller correctly captures the beginning and end of the device charge, and the charging time increases, as does the battery life of the device. You can calibrate the battery on both the iPhone, iPad, and other Apple devices.

How to tell if your iPhone battery needs to be calibrated

Signs that it's time to calibrate your battery on your smartphone are:

• early shutdown of the Apple iPhone when the battery is still present.
• the battery at a charge level of 30% sits down at a high unusual rate, and soon the iPhone turns off completely.
• the process of charging the battery is displayed unevenly: sometimes jumping, sometimes hovering in one place.

If this happens to your smartphone, then this article will help you properly calibrate the battery.

How to calibrate the battery

You can calibrate your iPhone from time to time and the process is quite simple. First, fully discharge your iPhone so that it turns itself off. Next, put the turned off iPhone on charge until the device displays 100% charge. In this state, we continue to charge the iPhone for another couple of hours, as the charge controller may incorrectly display its level. It is convenient to do this process at night, when no one will call you and you do not particularly need a smartphone.

After the battery is exactly 100 percent charged, we will perform the hard reset process, in which we simultaneously hold down the Home button and the Power button for about 20 seconds until the Apple logo appears. When calibrating, do not forget about the long margin of time required for this process.

Then we repeat the whole procedure again from beginning to end in the same order. This can be done 2-3 times in a row. At the same time, the principle should remain as follows: full discharge to 0% - full charge to 100% (no less!). Once the calibration is done, the battery should improve its performance and the charging failures should no longer occur.

How to ensure long battery life on iPhone 5

To extend the battery life on the fifth or other iPhone, you need to follow the basic operating rules that are designed to perform the functions of a smartphone for a long period.

The first rule is to observe the correct temperature regime when using a lithium-ion battery, avoiding overheating or hypothermia. That is, you can’t leave your smartphone in the open sun in hot weather and, conversely, at low temperatures, use a warm iPhone case and don’t leave it outside. With prolonged use of a smartphone at a high temperature of 50-60%, the battery will lose 40% of its capacity in just 2-3 months.

The second rule - do not continue to constantly charge the iPhone unnecessarily after the charge shows 100%, and at the same time do not bring the discharge of the iPhone to a complete shutdown if this can be avoided. It is better to recharge your iPhone on time than to bring it to a complete discharge. Poor handling of the battery in this case can result in its swelling and rupture of the device case. To prevent this from happening, the battery is equipped with a BMS chip that controls the process of recharging the iPhone, but it can also fail if handled improperly, for example, if you leave your smartphone on a long charge for several days.

The third rule is to work with the iPhone constantly in the mode from 70 to 20% of the charge level, and ideally - at 40% of the charge level. In this mode, the battery will last a long time and will be in good shape.

The fourth rule is to discharge the iPhone to 0% charge level at least once a month, but do not make it a rule to completely discharge the smartphone to this state all the time. Sometimes a full discharge of the battery allows you to keep the electrons in constant motion.

In general, do not allow your iPhone to be charged for 2-3 or more days in a row continuously.

The program shows changes, but they are not actually there.

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

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

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

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

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

Instead, I will use a more real source of information that you can trust - "Battery Health" from the menu "Settings" > "Battery":

And it was, and remains 87%.

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

This confirms two facts:

▪️ There is no point in calibrating the iPhone battery - we will see this a couple more 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 recharge cycles has stepped over 500, change the battery

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

iPhone battery controllers keep a close eye on them

How the Controller Controls iPhone Charging

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

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

The charging time depends on the power source you are using: standard AC adapter, iPad AC adapter, Power Delivery mode with MacBook AC adapter and Lightning to USB-C cable.

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

▪️ Boost charging mode. The remaining 20% ​​of the battery is charged with reduced current, and the energy level inside it reaches 100% gradually.

This is necessary for the battery. Therefore, even my iPhone 7 with 750 recharge cycles today feels quite normal and even shows the "Peak Performance" of the battery.

Battery controllers are calibrated during production

In the past, Apple did advise to periodically calibrate the batteries of its devices. Most likely, since then in the minds experts this concept remains.

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

Only devices with a removable battery need to be calibrated: MacBooks and MacBook Pros prior to 2009, as well as iBooks and PowerBooks.

Today iOS update is not scary

🕐 Please update iOS. A couple of years ago, Apple was accused of deliberately slowing down the iPhone with new versions of the operating system.

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

iPhone can and should be updated. Your best bet is to enable Auto Update altogether in 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 the 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 temperature. iPhone is best charged and used at temperatures between 0 and 35°C.

Any strenuous load in conditions that go beyond these limits can be fraught with battery.

📲 Charge without a case. Many models of cases (especially no-name ones) contribute to overheating of the battery.

If you notice that your iPhone gets warm while charging, remove the case first.

🗃 Store your iPhone properly. If you don't use your iPhone for a long time, make sure that the battery has about 50% energy.

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

When to change the battery in your favorite iPhone

500 cycles is not always the limit

The presence of specialized education and sufficient work experience allows me to state with confidence that I am very familiar with the principles of battery operation. Previously, having heard the question of how to calibrate iPhone and iPad battery, I would certainly think of its author as an amateur. However, a deeper study of the voiced problem convinced me that there is still a meaning in this phrase. The thing is that it is impossible to talk about battery calibration without taking into account the certain role of the software component.

I personally had to deal with an iPhone whose battery was draining at a frantic pace. The strangeness of the process was that for several hours the discharge of the battery led the phone to randomly turn off, but after a short “rest” the iPhone became usable again. The indications of the charge indicator indicated that the battery was 30% charged. Quite often, a complete discharge of the gadget occurred even with a battery charge of 50%. After using the charger, the amount of charge remained at the same level. I could safely disconnect the iPhone from the charger and continue using it.

With all my desire, I could not justify such an incomprehensible operation of the battery by the harsh conditions of its operation. The weather was quite warm outside, and I used the phone more than moderately. This inexplicable behavior of the battery prompted me to investigate in detail the possible calibration of the battery from the iPhone and iPad.

What does the battery calibration process involve?

There are factors, to challenge the truth of which it would not occur to anyone. We are talking about the deterioration of the properties of the battery with daily use. The value of the battery charge of only 1% also does not indicate its complete discharge. Setting the discharge and charge limits is the prerogative of a special controller, which can also fail. Malfunctions in the operation of this node lead to the fact that there are problems with the charge / discharge of the iPhone or iPad.

The situation can be corrected by taking the following actions:

The battery of the device must be completely discharged.
The battery should certainly be charged up to 100%, and then left to charge for 40-50 minutes. To charge the battery, it is better to use an outlet, since it is the industrial network that provides a high charge rate.
After disconnecting your device from the charger, the battery will have to be discharged again to 0%. At the same time, you should not connect your phone to a charger or a computer.
Once again we charge the iPhone or iPad up to 100% and, like last time, leave it connected to the charger for 40-50 minutes. In the same way, the procedure for discharging the device should be repeated.

This should stop. If conditions and time allow, the charge/discharge procedure can be repeated again.

These simple actions will most likely solve the iPhone shutdown problem. The key condition, the observance of which is mandatory, is the complete charge and discharge of the battery of the device. If this requirement is not met, the question of how to calibrate the iPhone and iPad battery will remain unresolved. By the way, the effectiveness of the described procedure for improving the battery life of the iPhone and iPad is also evidenced by the number of reviews posted on the network.

Modern electronic devices are highly dependent on the quality of components, whether it be a battery or a simple accessory. Everything must be of high quality in order to work for a long time and not refuse at the most inopportune moment. For example, you may be let down by a battery that has worked properly for several years, what to do in this case? Calibrating the battery on android and iOs devices or buying a new energy storage device will help. Before buying a new spare part, we will still try to restore and swing the battery of the device.

If you are reading this article, you are familiar with the problem of the device suddenly turning off at the most inopportune moment, even when the iPhone or Samsung shows that the charge is 50% or more left. This means that you have hit the so-called "Memory Effect". This can happen not only with NiCd but also with modern Li-Ion batteries.

Over time, the capacity decreases, but everything is recoverable, you can reanimate the battery by calibrating it. This is not a difficult procedure, but it takes time and care. If you do not have either, it is better to immediately abandon the idea of ​​\u200b\u200brestoring a Li-Ion battery, you can only make it worse.

It's time to restore the battery

Before embarking on radical methods to revive lithium-ion batteries, let's try to determine if there is a real need for this. We will analyze the main points when it is simply necessary to overclock the battery on a smartphone.

1. The operating time of an iPhone or Samsung on Android is constantly decreasing - if a new new smartphone lasted a day or two without recharging, and after a year of use it lasts a maximum of 12 hours. Then you definitely need to reanimate the battery. How to properly disperse a dying battery on a smartphone, we will tell the following chapters of the article.
2. Sometimes it happens that even immediately after turning off the charger, the samsung or iPhone immediately turns off, the battery is so “killed” by time and incorrect user actions that there is not enough energy even to load the operating system.

If you find out your situation in one of these points, then the question of how to restore the original battery capacity of the phone is not an empty phrase for you. Let's move on to practical actions.

Battery calibration

How to properly restore a Li-Ion phone battery to its original capacity? Several effective and inexpensive methods come to mind, applicable to both Android platform devices and iOs devices. The principles of operation of energy storage devices for smartphones, tablets, laptops are the same, so the instructions are universal and suitable for most electronic assistants.

• The first way is how to reanimate a battery made using Li-Ion technology or polymer. We put the smartphone on charge, as you usually do on a daily basis. Upon reaching 100% filling of the battery (according to the version of the device itself), turn it off using the button. Immediately after that, we again connect the power adapter with a cable, and wait for about a couple of hours, during this time, the battery will get the missing energy and restore the “memory” a little. We repeat the procedure for several days in a row, for 5-7 days it will be possible to observe a clear improvement in battery life.
• The second way, recovery of lithium-ion batteries. You need to try to land the electronic assistant to zero, so that even the screen does not display a request to connect to the charger. In the settings of the iPhone or Samsung on android, we set the screen backlight to the maximum level and launch a movie, a youtube video, a heavy toy, and wait until the battery gives up under the onslaught of high energy consumption. After this happens, we connect the charger and wait for the full completion of charging. After that, repeat the procedure up to 5-6 times. In most cases, this helps and overclocks even a new smartphone battery.

Applications and programs to help

In the previous section, we considered manual ones capable of calibrating the battery of an iPhone or Samsung phone on android. It's time to turn to the App Store and Google Play stores. In the open spaces of the virtual store, you can find many applications for the proper revitalization of lithium-ion batteries.

The sequence and logic of actions will be the same as when manually overclocking the battery on a smartphone, with the difference that some steps will be removed. For example, some applications themselves are able to discharge the battery to zero, starting the load on the main and video processors, which leads to the full consumption of stored energy in 30-40 minutes.

For Android

For android there is a battery calibration program called Battery Callibration. Convenient and not difficult to use.

Also, you can use the standard features of the operating system from Google. To do this, we transfer the device to "Recovery Mode" and go to the "Advanced" section, where we clear the records about the battery settings. I'll attach a video tutorial.

For iPhone

You can download the "Battery Life" application, but it can only be used to collect statistics, to calibrate the iPhone battery, it is better to use the manual method.

Doubtful and controversial options

There are quite a few rumors on the net about how to restore a lithium battery after a long and deep discharge. In most cases, these are fakes, you should not trust them. Here are a couple of examples (taken from the forums):

• We put the battery in the freezer for a day, then we charge it with a standard adapter and we get a “new battery”. Now I’m telling you how it really is - by putting an old and long-dead energy storage device into the freezer, you will only finish it off, since self-discharge will begin to accelerate at a negative temperature, and you will achieve absolutely nothing. Although a deep discharge of the battery is 100% provided to you, followed by a slow “dying” of the battery.
• Rumor has it that it is possible to restore a swollen phone battery, but this is not so, it is better to get rid of it by throwing it in the trash and buy a new one. This is an already used element, we do not recommend installing it in your iPhone or Samsung device.

Summarize

• It is best to manually calibrate the battery.
• Overclocking a new battery is pointless.
• It is not possible to revive the battery by freezing, it is checked.

Observe the modes of storage and use of iPhone and Samsung smartphones on android, periodically (every 2-3 months) calibrate the battery, and your gadgets will work for many years before going under the screwdrivers of the masters from service centers.

Increase iPhone battery life here and now - only proven ways.

iPhone battery capacity is growing, but iOS is not getting more optimized in terms of power consumption, and therefore one of the most discussed topics among Apple smartphone users is still related to iPhone fast draining problems. In this article, we have collected all the proven ways that allow you to both increase the battery life of your iPhone here and now, and extend the life of your smartphone battery in the future.

About iPhone batteries

All modern Apple devices use lithium-ion batteries. Compared to conventional batteries, such as nickel-metal hydride batteries, they have a number of advantages. Lithium-ion batteries are lighter, have higher capacity, short charging times, and most importantly, they are durable. The last statement is true, provided that the batteries are operated in the right way.

How to Extend iPhone Battery Life

There are a few basic rules that can greatly extend the life of your iPhone battery.

1. Do not allow the battery to completely discharge

One of the features of lithium-ion batteries is the almost complete absence of the so-called memory effect. This concept refers to a reversible loss of capacity, which occurs when the charging mode is violated, in particular, when charging an incompletely discharged battery. Since the iPhone battery has little to no memory effect, charging your smartphone is highly recommended before it shuts down due to lack of power.

More specifically, it is necessary to connect the iPhone to the charger when the battery level drops below 10-20%. How much will it help? Experts have found that the amount of life of a lithium-ion battery due to this ratio increases up to 2.5 times. Much more useful for the battery and at all do not lower its charge level below 50% .

2. Avoid overheating and hypothermia

Heat and cold are the worst enemies of lithium-ion batteries. Overheating and hypothermia of the iPhone can significantly reduce the battery capacity of the smartphone, so you should never keep it in adverse conditions.

For the sake of completeness in this guide, we note that the iPhone can be used without endangering battery life at temperatures between 0 and 35°C. To be stored - at a temperature from -20 to 45 °C.

3. Use the original charger

In the case of the iPhone, this point is especially important. The original charging for Apple smartphones is not cheap, and Chinese alternatives, on the contrary, attract with their availability. However, it’s better to pay a lump sum once than a few months later to type in the search query “Why is my iPhone running out of power so quickly.”

Why are non-original iPhone chargers so bad? Cheap chargers are mostly made "on the knee". There are hundreds of disassemblies of Chinese exercises on the Web, which show that craftsmen from the Celestial Empire do not strain at all over the design of their two-dollar accessory. The build quality of such chargers is extremely low, and the power is half that of Apple models. In addition, the insulation is quite often very lame, which means that such accessories are simply life-threatening.

4. Discharge your iPhone every three months

If you decide to start following (or are already following) the first advice, then you need to know something else. Full charge of lithium-ion batteries for a long time is just as harmful as the constant discharge to zero. Due to the fact that the charging process is chaotic for most users (we charge our iPhones at the first opportunity), experts strongly recommend that you fully discharge the iPhone every three months. And you need to do it in a special way.

After a long work of the iPhone without turning off, the smartphone must be completely discharged, then charged to 100% and kept on charge for an additional 8-12 hours. Such a simple trick will allow you to reset the so-called upper and lower battery charge flags.

5. Charge your iPhone without a case

Some iPhone cases can cause the battery to overheat, which can affect its capacity. Determining whether your case is detrimental to your smartphone is very simple. If you notice that your iPhone gets very hot while charging, the first step is to remove it from its case.

How to Store an iPhone

Separately, it is worth talking about how to properly store unused iPhone. When sending an old iPhone to a distant shelf, make sure that the charge level of its battery is 30-50%. Long-term storage of the iPhone with a completely discharged battery will eventually lead to a decrease in its capacity, and a significant one.

How to increase iPhone battery life

We figured out the correct operation of the iPhone to extend the life of its battery, let's move on to the most interesting - ways to increase the operating time of Apple smartphones without the need for recharging.

1. Start using the power saving mode

Since iOS 9, Apple has offered iPhone owners to use the power saving mode. " Power saving mode lets you extend your iPhone's battery life by up to three additional hours. The mode is activated in the menu " Settings» → « Battery».

How does Power Saving Mode increase battery life? When it is activated, the device's performance, network activity are slightly reduced, motion effects, mail checking, background application refresh are turned off, and animated wallpapers turn into static ones. In other words, the mode does not affect the main functions of the iPhone, the smartphone, as before, remains able to cope with any tasks.

2. Decrease display brightness

Do not get upset ahead of time, we will not talk about the banal setting of the minimum display brightness in the menu " Settings» → « Screen and brightness". We'll walk you through an advanced way to reduce brightness using your iPhone's accessibility settings.

Step 1. Go to the menu " Settings» → « Main» → « Universal access».

Step 2. Select " Increase” and turn on the switch of the same name.

Step 3. Tap the display three times with three fingers. A window with magnification mode settings will open.

Step 4. Set the minimum magnification and click " In full screen».

Step 5. Go to the " Select filter” and select “ weak light". To close the settings menu, tap anywhere on the screen.

Step 6. Go to the menu " Settings» → « Main» → « Universal access» → « Keyboard shortcut' and check the box ' Increase».

As a result of applying these settings, you get the ability to triple-click the Home button to set the minimum brightness on the iPhone. The display will begin to load the battery less and the smartphone will be able to work longer. To exit the minimum brightness mode, press the Home button three times again.

3. Set the minimum display lock time

A simple but extremely useful setup. On the menu " Settings» → « Screen and brightness» → « Auto-lock» check the box « 30 s". This will allow the iPhone display to automatically lock after just 30 seconds of inactivity.

4. Turn on "Reduce Motion"

There is another option in the accessibility settings, the activation of which has a positive effect on the battery life of the iPhone. We are talking about the “Reduce Motion” option, which reduces the movement of the user interface by enabling parallax on the icons. The iPhone does not waste its resources on playing unnecessary animations, saving them for more useful tasks. Turns on " Reduced motion" on the menu " Settings» → « Main» → « Universal access».

5. Turn off Background Content Refresh

The more applications on your iPhone that access the Internet for any information, the faster the smartphone is discharged. Fortunately, their activity is very easy to deal with. Go to menu " Settings» → « Main» → « Content update” and turn off the applications whose background activity you want to block.

6. Turn off unnecessary pop-up notifications

Each app notification on iPhone wakes up the display, which is known to be the most battery draining. That is why it is recommended to keep the list of applications with enabled pop-up notifications in order. Go to menu " Settings» → « Notifications» and turn off notifications from unnecessary applications.

7. Use an ad blocker in Safari

If you actively use the Safari browser on your iPhone, then any ad blocker will help increase battery life. Many do not know, but interstitials and pop-up banners on websites are an additional and not the weakest load on the device. The App Store has a large number of free ad blockers, for example, adguard .

8. Turn on "Airplane Mode" when the mobile network signal is weak

When the iPhone cannot establish a stable connection to the cellular network, it starts sending signals to the carrier over and over again. The smartphone spends a lot of effort on this operation, and, accordingly, the battery charge. Airplane mode allows you to prevent the iPhone from sending signals to the carrier without stopping when the connection is poor.

9. Disable Wi-Fi Auto Search

By default, the iPhone is constantly in the mode of searching for available wireless networks, which most often users do not need. Scanning affects the battery charge very much, of course, for the worse. Fortunately, you can turn off the automatic search for Wi-Fi networks. To do this, go to the menu " Settings» → WiFi and toggle switch " Connection request» to inactive position.

10. Disable AirDrop

The AirDrop feature makes it very easy to share files between Apple devices, but not everyone uses it. If you don't use AirDrop either, feel free to open " Command centre", click on AirDrop and select " Receive Off” to prevent the function from wasting battery power.

11. Prevent some apps from using location services

A huge number of applications use iPhone location services. And quite often - in vain. But tracking your location with a smartphone is an extremely resource-intensive process. Of course, it is not recommended to completely disable geolocation services, but it is worth prohibiting specific applications from using the function. Go to menu " Settings» → « Confidentiality", select the application that should not be able to use location services and click " Never". Go through the entire list of installed applications and leave only really important tools, such as a navigator, allowed to work with the function.
