How to calibrate the battery of an Android phone. Calibrate
Android battery: all the steps to be performed. One of the elements that makes
phone users headaches is, without a doubt, the battery. Aware of the importance
of having a good autonomy, manufacturers are increasing the capacity of the
batteries, introducing solutions to optimize energy consumption .
For our part, we have already explained to you on other
occasions how to keep track of charge cycles , how to charge it to extend its
useful life and even how to save energy by configuring apps in standby. The
Android operating system has a file called Battery Stats, which indicates the
capacity of the battery when it is full or empty. The problem is that this file
sometimes gets corrupted and starts showing non-real data, which causes the
cell to freeze before it reaches 0% or that, once loaded to 100%, it quickly
runs out.
The battery calibration process involves correcting the
values of this file and does not repair anything physical or chemical in the
battery, that is, it is a software correction, not a hardware correction. Today
we will explain a process that should be repeated every two or three months:

Because we need to periodically calibrate the battery of an
Android phone
The charge percentage of a mobile phone is calculated based
on a series of algorithms executed by the system and based on the battery
capacity, the time it was charged and the maximum charge point, which is
reached after a time. If any of these are wrong, we can find a deviation in the
calculations and, therefore, we have before us a badly calibrated battery that
shows us the wrong percentage.
Therefore, keeping the battery calibrated is useful twice:
on the one hand, it is good for us because we will be able to see a reliable
percentage of charge and our mobile phone will not turn off suddenly and, on
the other hand, it is healthy for the battery itself, because it will help us
maintain an optimal charge level (between 40 and 80%).
In the app stores you can find several apps that promise a
battery calibration, but our recommendation is to perform the calibration
process yourself. As we will see, it is a very simple process that is
recommended to be repeated every two or three months.
When to recalibrate a
battery?
When you notice that the battery never reaches 100%, but
freezes at 90 or 95%, or when the smartphone turns off suddenly, for no reason
or when the battery drains very quickly.

battery of an Android phone
However, if the battery life of the smartphone has started
to shorten for no apparent reason, it may be time to calibrate it. Here's how to calibrate the battery of any Android
phone .
Unlike Apple, which provides a specific calibration
procedure for the iPhone battery, the rest of the Android manufacturers do not
generally specify standards for calibrating the battery of their phones. Below
we offer a general method that you can perform on any device regardless of its brand:
Fully charge the phone battery : connect it to the charger
and wait until the battery indicator charges 100%, but do not disconnect it
immediately when it reaches 100%, leave it a little longer.
Fully discharge the battery : after fully charging it, using
the phone normally or intensely, fully discharge the battery until the phone
turns itself off. Demanding applications, games or multimedia content will help
you consume energy faster.
Leave the mobile phone to rest for at least 4 hours : the
battery may have a residual excess charge that causes it to fail to calibrate,
so that during these hours of rest, the residual energy is released from the
battery itself.
Recharge your mobile phone : once it has been fully
discharged and you have waited at least 4 hours, recharge your mobile phone
until it reaches 100% charge and wait a little longer to make sure it is fully
charged before disconnecting it.
Turn the phone back on
and use it again normally: if you have completed the process, it should
already be properly calibrated so that you can use it without problems for two
or three months.
How to calibrate the battery of an Android phone with an app
Download the AccuBattery app
from the Play Store . This app will show the battery charge in milliamps
(mA) in the notification bar. You should charge your smartphone until the app
shows 100%. When you reach 100%, turn off and restart the device. Through this
procedure you have calibrated the
battery of your Android smartphone .
GO Battery Pro - Battery Saver monitors applications and
decides which ones most affect battery power. By clicking the
"Optimize" button, any unnecessary applications that currently
consume resources are deleted.
Avast Battery Saver
increases battery life by stopping all applications that are not used,
optimizing device settings. It also has 4 predefined profiles: Home, Work,
Night and Emergency, which simplify everything.
