How to calibrate the battery in an Android mobile

23 mayo, 2021

One of the elements of the phones that gives users the most headaches is, without a doubt, the battery. Aware of the importance of good autonomy, manufacturers are increasing the capacity of batteries, while introducing solutions to optimize energy consumption. We, for our part, have already explained to you on other occasions how to keep track of the charging cycles, how to charge it to extend its useful life and even how to save energy by configuring the standby apps.

And it is that the importance of the battery in a mobile phone does not happen just because it can run out at the most inopportune moment, but because, unlike other components, it degrades over time. For that reason, today we are going to explain a process that It is advisable to repeat every two or three months: calibrate the battery of your Android mobile.

Why should we periodically calibrate the battery?

The percentage of charge of a mobile is calculated based on a series of algorithms that the system executes and that are based on the capacity of the battery, the time that we have been charging it and the maximum charge point, which is reached after a while. If any of them fail, we can find a deviation in the calculations and, therefore, have before us a discalibrated battery that shows us an erroneous percentage.

How to know the health status of your Android battery and how it can lose capacity

Therefore, keep the battery calibrated it is beneficial twice: On the one hand, it is good for us because we will be able to see a reliable charge percentage and the mobile will not turn off suddenly, and on the other, it is healthy for the battery itself, because it will help us maintain an optimal level of charge (between 40 and 80%).

In the app stores, it is possible to find different alternatives that promise a battery calibration, but our recommendation is that you do not trust themInstead, do the calibration process yourself. As we will see, it is a very simple process that is advisable to repeat every two or three months.

How to calibrate the battery in an Android mobile


Unlike Apple, which does establish a specific calibration procedure for the iPhone, the rest of Android manufacturers do not usually specify standards to calibrate the battery of their mobiles. Here, we are going to propose you a general method that you can apply with any device regardless of your brand:

  1. Fully charge the mobile battery– Connect it to the charger and wait until the battery indicator charges 100%, but do not unplug it immediately when it reaches 100%, leave it a little longer to make sure that the decalibration does not affect the upper limit of the charge.

  2. Discharges the battery completely: once you have fully charged it, either using the mobile normally or intensively, discharge its battery completely until the mobile turns off by itself. Demanding applications, games or multimedia content will help you consume energy faster.

  3. Let the mobile rest for at least 4 hours: the battery may have a residual excess charge that causes it to be decalibrated, so that, during these hours of rest, this residual energy should be released by the battery itself.

  4. Reload the mobile: Once it has been completely discharged and you have waited at least 4 hours, recharge the mobile until it reaches 100% charge and wait again a while to make sure it is fully charged before unplugging it.

  5. Turn on the mobile again and use it normally again: if you have completed the process, it should already be calibrated correctly so that you can use it without problems for two or three months.
