Using the Recovery menu

How to calibrate the battery without root access

Method 1.
First you need to find out the full capacity of your battery in milliamp-hours. To do this, you need to look under the battery, where all the information about it is stored, or you can find information on the Internet, in some review where the characteristics of your model are indicated. After this, you should install the calibration program on the device from Play Market. There are a lot of them, but the most effective is Current Widget: Battery Monitor.

Using this program you can find out the battery charge in milliamps (mah). From this point on, you should charge the device to the maximum charge level. After this, you should turn off and turn on the device again. This action will let the phone know what the real and valid battery limit should be. If this method does not work, then you can try to do five cycles of charging and discharging the device and after the fifth time remove the charger and perform hard reset phone or tablet. Hard reset will reset all created settings to their original state, but the command does not work on all Android operating systems.

Method 2.
The next method for calibrating the Android battery is extremely similar to the first, the only difference is that you do not need to install additional applications. To do this, you need to charge your phone to maximum value. After this, disconnect the charger and turn off the phone. Then connect again charging cable and wait until the LED indicator starts to light up green, indicating that the battery is fully charged. Then you need to turn on the phone and remove the auto screen off function. This action can be done using the settings. All this is needed to ensure that the phone runs out faster. After the absolute discharge cycle, we charge it again to the maximum value. After all operations, the Android operating system should use the battery sparingly and perform a full discharge cycle.

Android battery calibration program

You need to install the calibration program from the Play market. There are a lot of them, but the most common is Battery Calibration. After installing this application, you need to charge your phone or tablet to the maximum charge, and then launch this application.

The charge values on the display and in the application will differ significantly, so you need to wait until they reach same value. As soon as they become the same, you need to press the “battery calibration” button. Your device's battery is now calibrated. This method is similar to the one we did without root access.

Calibration using Recovery

Need to go to Recovery mode on Android (Usually this is by holding down the power button and the volume + button on the device that is turned off) and go to additional section settings where the “wipe battery stats” function is located.

It will delete all previously made settings and settings. After resetting all previous settings, you should completely discharge the device. After that, put it on charge again and charge to the maximum value. When the maximum charge value is reached, you need to go back to the application and perform calibration. This action will strengthen the settings and increase the functionality of the Android operating system.

There are cases among users that each of the methods does not work. This happens because the battery it uses is more than five years old and any calibration will not help here. When buying a new phone, it is recommended to perform several cycles at once complete discharge and charging. This action will increase the functionality of the phone and ensure long-term operation.

At a certain point, a smartphone or tablet may begin to discharge much faster than before. Our website already explains why the device begins to discharge quickly. If nothing helps you, do not rush to run to a service center and replace the battery with a new one; it is quite possible that you just need to calibrate the battery.

What is battery calibration on a phone or tablet?

Battery calibration is measuring the capacity and, roughly speaking, editing the battery. As a result of calibration, the battery is used more efficiently and its service life can be significantly extended.

Signs that your battery needs calibration

It takes a long time to charge the device, for example, not a couple of hours as before, but 4-5 hours.

Significantly shorter operating time of the device on one charge.

Even with long charging The indicator does not want to show 100% charge.

The device turns off when there is no power, although you do not receive any signals from the battery indicator.

If you encounter this kind of trouble, it makes sense to try calibrating the battery. True, it is initially worth considering other options. Here's an example from real life: a user updated his smartphone over the air to new version firmware that was just released for his device. After the update, he noticed that the smartphone began to discharge quickly. In this case, the problem arose precisely because of the firmware, since after a couple of days it was released additional update, which solved the problem of fast discharge. These are the types of cases that need to be taken into account.

If you do decide to calibrate, let's talk about it.

Manual calibration

In this case, no third party applications are not used, only the device itself and charging are needed. Ruth, that is, superuser rights, is also not needed.

The device needs to be completely discharged.

Then start charging it with it turned on for 8 hours.

Turn off the device and continue charging it for another 2 hours.

Disconnect the device from charging, turn it on for 2 minutes, turn it off and connect it to charge again. This time charge for 1 hour.

Calibration is complete, turn on the device.

Calibration using software

This option is suitable if you have it installed on your device. Download the Battery Calibration app from Google Play Market, install and run.

When you launch it for the first time, you need to provide root rights, otherwise the application will not work.

And here further instructions, which is not mentioned everywhere:

Connect your device to the charger.

Wait until it charges to 100%.

Click the Battery Calibration button.

Unplug the charger.

Discharge your device before turning it off.

Charge it to 100% without interruption.

In fact, the application deletes system file batterystats.bin and then the system automatically generates clean file. Any old information, which could cause the battery to work incorrectly, will not be present in this file.

Problems with your smartphone's battery are probably one of the most common occurrences, and that's why we are looking for new ideas and suggestions on how to better deal with this problem. Battery consumption may be uneven and you need to figure out where the problem is. You can also try calibrating your Android's battery, which can significantly improve performance, if that's possible with your phone.

In this article, we'll take a closer look at how you can calibrate your phone's battery.
Our first suggestion for improving power consumption will be our article "Saving battery power by various smartphones" Even after these tips, the problem still persists and then it is time to calibrate the battery. The biggest battery problem is when it runs out extremely quickly, or the phone simply won't turn on.

Before replacing the battery, try calibrating it. This may be the only way that is used in most cases!

Battery calibration - what does it mean?

Every Android phone has a battery app that displays all the necessary battery stats for your phone. The app is very informative as it shows the battery percentage, battery life and battery consumption. various applications using your battery resource.

In some cases, when your battery is not calibrated, this application may produce errors in statistics. Battery calibration can correct this problem and hopefully improve performance.

Calibrating your Android's battery - on non-rooted phones

First, don't forget to check the battery capacity. If you're not sure, look up your phone's battery specs online. You can find detailed specifications model of your phone, on the website of your phone manufacturer.

After that, look for an application called "Battery Monitor" " You can find the application for download on the Google Play store.

The unique feature of this app is that it will show you the charging parameter in milliamperes (MA). Of course it is great help, when you need to charge the battery to a certain level indicated by the battery capacity. When you reach the required level, simply turn off your phone, turn it off and turn it on again. If everything is done as noted, your phone's battery will be charged 100%

An alternative way to calibrate your Android's battery:

Fully charge the battery and once this is done, simply turn off the phone.

After turning it off, plug it back into the charger and charge your phone to 100 percent again. You'll know your phone is at 100 percent charge when you see a green light on your phone.

Now turn your phone back on. Go to the display settings tab and select the option to keep the screen backlight on. Now connect your phone to the charger and charge it to full 100% again.

Finally after this, turn off the phone and let the battery drain to 0% and the phone will turn off by itself. It's a long process, but it has to be done this way for proper operation calibration process.

What can drain your phone battery?

It is worth noting that modern firmware phones are full-fledged mobile operating systems. This means that while the phone is running, “background” processes are required, such as: SMS messaging service, Text input service, Antiviruses, etc.

Accordingly for work background processes it is also necessary to spend on them both power central processor, random access memory and of course - battery charge.

During “active” use of the phone (for example, starting various programs: Internet browser, Games, Bank account access programs, Mail programs etc.) we recommend restarting your mobile phone. To do this, you need to press and hold the “Power” button of your phone and select “Restart”.

If all else fails

After long term use of your phone - the battery becomes unusable over time. But even from this situation there is a way out, for example:

Battery for charging your phone(PowerBank) solar powered

Pros: low cost and charging from solar energy and from the car charger. The disadvantages are obvious - it will increase the weight of your bag by about 200 grams. There are quite a lot on the market Chinese versions similar devices, but we settled on this one: .

Battery calibration results

After a somewhat complicated battery calibration process there is hope of giving your charger a new one life cycle. Have you tried any of the methods mentioned above or do you have your own? own way optimizing your Android battery?

We'd love to hear your thoughts in the comments below.

Phones and tablets working in the operating room Android system have long acquired a reputation for being “all-consuming” energy devices. Many people are probably familiar with the situation when a gadget starts to turn itself off when the battery charge has not yet been completely used up, for example, there is still 50 or 70% of the charge left.

The first thought in such a situation is to buy new battery. But my advice to you is don’t rush, it’s just that your OS has not correctly remembered the power consumption mode and is starting to manage the battery not quite correctly, you just need to calibrate the battery and if it doesn’t help, then you can safely go to the store for a new battery.

How to calibrate an Android battery?

There are several ways to set up economical energy consumption. Some require root access, others do not. We will describe each method so that you choose the one that suits you.

How do I know if my tablet has battery problems?

Before you start dealing with a problem, you need to identify it and admit that it exists. After all, maybe the tablet works fine for you and the battery holds a charge well, and you are already trying to calibrate it.

1. We have already described the first sign above - if the Android device, for no apparent reason, starts to turn off before the battery is completely discharged. These are the cases when the battery charge is still displayed on the screen and maybe even 95%, but the tablet or smartphone nevertheless turns off.

2. Second sign - rapid decline battery life of the device. For example, if after purchase your tablet lasted 5 days, and after a month it became 4 days, after another month of use - 3 days. This is a sure sign correct settings batteries that require calibration.

What does calibration mean?

If you look in the dictionary, this means setting up or bringing an instrument/device to an optimal state. Often used in electrics when it is necessary to configure a device to certain standards.

In our case, this is tuning (calibrating) the battery in order to improve energy consumption so that it is in optimal shape and therefore holds the battery charge for as long as possible.

Android battery calibration without root access

Method 1

First, you need to find out the capacity of the test battery in milliamp-hours (mAh). You can find information on the Internet, in some review of your tablet model, or just look under the battery, most often the characteristics are written on it.

Ampere is a unit of current measurement; mAh measures the battery capacity. It means how many milliamps the battery can provide for one hour. If consumption increases, then the capacity indicator drops.

The next step is to install the CurrentWidget: Battery Monitor program from the Play Market. This app will show the battery charge in milliamps (mA). Now, by monitoring the charge level, you need to charge the battery to the capacity specified by the manufacturer.

When the required number of milliamps is reached, turn off the tablet and start it up. By rebooting the device, you will let it know what the current battery level is.

If it doesn’t help, then try another modification of this battery calibration method - do 5 full charge/discharge cycles of the phone so that when fully charged, the battery capacity reaches the required maximum in mAh. After the last fifth fully charged, remove the charger, wait 10-20 seconds and do a hard reset of the tablet.

After these manipulations, the device must remember the required charge level and take it as 100%.

Hard Reset - full reset all settings, rollback to factory settings. To do this, dial *#*#7780#*#* and press the call button. This USSD request Doesn't work on all Android devices!

Method 2

The second method is a kind of variation of the first, the only difference is that you do not need to install special programs, just work with charging.

To calibrate the battery, charge the battery until full condition so that the screen shows a level of 100%, then unplug the charger and turn off the tablet (phone). Then connect the charging cable to the disconnected device and continue charging the battery until led indicator(LED) will not turn green, indicating that the battery is fully charged.
Turn on the device again and remove the option automatic shutdown screen (usually on Android: display settings -> sleep mode). Now that your tablet has stopped going into sleep mode, we begin to charge the battery to 100% again.
It is necessary to disable sleep mode in order for the device to shut down faster. Therefore, after fully charging, we leave the tablet with the display on and wait for it to completely discharge.
We charge our device again and that’s it, now Android should use the battery correctly and follow the full discharge cycle. Don't forget to turn Sleep Mode back on!

Calibrating the battery of a Tablet with Android and root access

C root access There are several calibration methods. If one of them does not work, then there is a high probability that the second will give results.

Method 1 - Battery Calibration
Install the Battery Calibration program from the Play Market. Then connect the charger and charge the battery to 100%. Then open the Battery Calibration application and look at the battery level in the program, as most likely it will differ from what is shown on the display.

Continue charging the tablet until it reaches 100% according to Battery Calibration. When the charge level reaches the maximum, press the “battery calibration” button, and then reboot. That's it, we have calibrated our Android tablet.

As with non-root battery calibration, we're trying to give Android "reference points" so it can see when the battery is fully charged and when it's low.

Method 2 - Recovery mode

1. Go to Recovery mode on Android and go to the Advanced section, where you will find the “wipe battery stats” option. This will remove any previously made calibrations by you or the system itself.

Recovery mode is a recovery mode in Android. On different types devices, the method of booting into Recovery mode is different, but often the actions are something like this: on the device turned off, press the volume up button, then press Home button, after which you need to press the power button. All three buttons must be pressed simultaneously, not one after another!

Video example of booting into Recovery mode:

2. After resetting all previous Android calibrations, completely discharge the battery before turning off the device. After that, put the disconnected device on charge, and without turning it on, charge it to full.

3. Turn on your tablet/smartphone without unplugging the power cable and perform calibration in the Battery Calibration app. With this step we will further strengthen the settings and let Android understand what we need.

If the batteries are already 5-10 years old, then you no longer need to think about calibration, but about buying a new one. And don't be surprised if the above methods don't work on your devices;
On new devices, always do several cycles of complete discharge - charging the battery, calibration can also be done;
If all else fails, check your charging cable, maybe there is a problem with it;
Do not constantly charge from USB. Use this method only in extreme cases when there is no normal outlet;
It is not recommended to use non-original ones charging device- they can quickly drain your battery and it will no longer be capable of delivering the number of milliamp hours for which it is designed;
If the device has fallen, floated, or floated, these methods may not help. In this case, please contact service centers, let them clean and repair. Because miracles only happen in fairy tales!
If you constantly fly on an airplane or go to the mountains, then don’t be surprised at how quickly your battery drains; it’s not a matter of Android and calibration, but of physics.

It is impossible to imagine modern man without mobile phone and tablet computer.

We use these devices more than once every day, and some almost never let go of their gadget. But what more people uses his electronic equipment, the faster its battery discharges.

Based on this, the question arises: is it possible to somehow extend the operation of the smartphone or personal computer? It is possible, and there is a solution to this problem - you just need to calibrate the gadget’s battery. When should this procedure be performed?

If new smartphone actively used for about 2-3 days and the amount of charge remained the same;
If your phone battery starts to drain quickly.

There are two ways to calibrate the battery - using a special program and manually. So, if you always don’t have enough battery power on your Android device, let’s start calibrating.

The first and easiest way to calibrate an Android battery:

You will need to download from Play Market special program to calibrate the battery “Battery Calibration” and install it on electronic device.

It is suitable for all types of equipment and can be installed on both phones and tablets. operating system android. After installation, launch the program and monitor the information on the screen of your electronic device.

The battery itself will perform all the manipulations, and the calibration will be completed and completed.

One caveat - to use the Battery Calibration program you will need Root rights access. If you don't have them, it is recommended to use.

You can use the second method to calibrate the battery

You will need free time and a great desire to have a battery with for a long time active use. IN in this case everything is done by hand.

Let's start calibration:

We charge the electronic device with it turned on for 8 hours. Before doing this, it is recommended to completely discharge it so that the charge is 0%.
Turn off your phone or tablet completely and charge it for another 2 hours while it's off.
Unplug your device and turn it on for 2 minutes.
Turn off your phone and let it charge for another 1 hour.

After these manipulations, the electronic device on Android will delight its owners with a long battery charge.

This method of calibrating the battery is suitable for both smartphones and tablets, since both devices charge exactly the same. Battery calibration is recommended for all types of devices that, for some reason, do not charge to 100%.

Such situations do occur, and instead of going to a service center and giving your device for flashing, try to deal with it on your own first.

There will definitely be no harm from this manipulation, but the battery power will definitely increase, and your gadget will hold its charge much longer.

This video shows another way to configure the battery.
