How to calibrate the battery

Battery problems are a major concern for smartphone users, especially at a time when their life is starting to shrink.

How to calibrate the battery

That's why we offer you these tips and tricks so that you can get the most out of it. It's time to calibrate your Android battery.

First of all, the main thing is to have general knowledge about the battery of your smartphone.

It's also good to know which applications consume a lot of battery power, as they can be the culprits of your device's low autonomy.

One of the most widespread symptoms is that our mobile quickly runs out of power or that the terminal, even with a battery, switches itself off and restarts if it is not connected to the charger. This may be due to a damaged battery.

The Myth of Battery Calibration: Wipe Battery Stats

In Google Play we can find hundreds of applications to calibrate the battery, methods with root and without root and even applications that promise to repair it.

And yes, you're right, as you suspect none of these applications will help improve the life of your battery or repair any damaged cells.

In some forums it is also recommended for root users to delete the system file data/system/batterystats.bin, which can also be deleted in some recoverys with 'wipe battery stats'.

The truth is that this method does not help or have any impact on the life of our battery as stated a few years ago by Google engineer Dianne Hackborn.

In addition, Hackborn clarifies that this file does not control the battery percentage that appears in the status bar and the file itself is reset each time you unplug the device from the charger after a full charge.

How to calibrate the battery

Warning: If the battery starts to cause problems, the most normal thing is that it is damaged and there is no turning back: you have to replace it.

As noted above, calibrating your battery does not allow your battery to 'revive' and, in fact, today the processor's power management is very good and does not need calibration.

Until 2015 LG recommended calibrating the battery every 3 months (due to a cumulative error of the digital control), and as engineer Dianne Hackborn told us the process is as simple as charging the battery completely. According to LG this is the best method to calibrate the battery of your old models:

  • Use the device until it turns off.
  • Let him rest for about six hours without using it.
  • Charge it and when it reaches 100%, leave it plugged into the charger for another 2 hours.
  • Disconnect and you can use it normally.

Why your smartphone's battery lasts so little

Let's analyze the problem

Let's start from the beginning. We need to know the behaviour of our battery in order to be able to locate the problem and then look for a solution.

In any Android smartphone we will find the possibility to see in detail which processes or applications are consuming battery.

To do this, go to Settings > Battery. If we see that some element of the list offers an exorbitant use we will be able to close the process.

If this information isn't enough for you and you need more, on Google Play you'll find a number of applications that offer statistics and more detailed information on battery consumption.

I personally recommend GSam Battery Monitor. After downloading it, we only have to wait a couple of days for it to gather all the necessary data to create the statistics. Of course, there are also applications that will help us save battery power.

After discovering how we can locate the problem, we compile a list of the most common ones and their solutions.

Your screen consumes too much

In many cases it is the screen that consumes most of the battery. Normally, the screen should not consume more than 15%, although this already sounds almost idyllic considering that the screens keep growing and having higher resolutions.

That is why I would say that it can reach 20%, but if consumption exceeds that figure, then it is time to remedy it.


As simple as lowering the brightness of the screen. All manufacturers add an automatic brightness mode, which is adjusted according to light conditions.

I wouldn't recommend it, because that calculation of constant light conditions also consumes battery power and, moreover, the phone may decide something that doesn't match what we need.

That's why I prefer to adjust it manually. Usually, I put the brightness very low and when I see that I need more light I raise it a little.

The battery doesn't give more than itself

If your smartphone is a couple of years old, the problem may simply be that the battery is already starting to float.

In this case, it would not be a software defect, but a hardware defect. All batteries have a maximum of life cycles and, at some point, low performance.

Manufacturers often say the standard is 1000 cycles, but that depends on many factors.


If you have a smartphone with a removable battery, it's easy - just replace it. This was one of the main advantages of removable batteries.

If that's not your case, you can either try changing the battery yourself if you're a handyman or take your phone to a specialist technical service.

Another possible solution only suitable for roots is to force Doze mode with the Force Doze application, this way you will get your battery to benefit from one of the best Marshmallow features.

Charger does not work

We may find that the battery does not charge well. This is because the charger or plug on the microUSB port is defective or damaged.


Check if your cable works on another phone or vice versa, try another cable on your smartphone.

That way you can better locate the problem. In the case of the microUSB port, we recommend you to read our tutorial about the problems when charging our smartphone.

An application behaves strangely

Many times, after an update, one of the applications can go crazy and start consuming more energy than necessary for no apparent reason.

The first thing is to find out which application it is, just follow the steps specified at the beginning of the article.


Once we have located the application we go to Settings > Applications > In progress. Select the application in question and select Force Stop. In the following article you can find out which applications consume the most battery.

Android System' consumes as the most

You've probably discovered that one of the most battery-consuming processes is called the Android System.

In practice, you should not consume more than a quarter of the total, if you are consuming more, we have a problem. This means that the system is consuming more resources than it should.


If the problem is due to a faulty update, it is best to go back to the previous version. Another possible solution is, even if it sounds a little drastic, to restore the factory data.

In some cases, through this process we go back to the previous version and, therefore, we won't have to go through flashes and complications.

Don't forget, if you are going to restore at the factory, to make a backup so as not to lose any data you have on your smartphone.

Google Play Services

I don't know about you, but in my case, Google Play Services consume a lot of battery power and I find it quite tedious.

I understand that it's part of my smartphone and that it exists to allow applications to synchronize. But another thing is certain, these services are not always optimized and although they are improving, my battery suffers.


There are several options. The first is to go to Settings > Applications > All > Google Play Services.

Then we can clear Google Play Services cache. It's also a good idea to have the latest version of Google Play Services.

You don't need anything? Don't go yet, there's more!

Don't get discouraged. There's a Plan B. You can always turn on Power Save mode that will limit device performance, vibration, location services, and background data transmission.

You can activate this mode in Settings > Battery now play the top three points on the right, select Battery Saver and activate it.

You won't receive notifications of messages but they will be there if you open the application, but at least you'll be able to keep the device a little longer awake.
