Mobile phones have come a long way over the years. From being simple tools to call and send messages, we suddenly find ourselves with pocket multimedia centers with which we can do practically everything. There is one aspect, yes, in which they continue to weaken: the thorny issue of batteries. And no, we are not referring to the issue of autonomy, something that has been improved over time. What we are talking about is that, unlike other components, batteries tend to degrade over time. For the same reason, we are going to talk about a process that should be carried out every two or three months: calibrating the battery of your Android.

Why is it important to calibrate the battery?

That is a good question. To answer it, we first have to start talking about the percentage of battery that we see as remaining in our phone. This percentage is calculated based on a series of algorithms that the operating system executes, based on the capacity of the battery itself, the time it has been charging and the maximum charge point.

As a general rule, these calculations are not usually wrong, but it may happen that at a given moment something deviates a little from normality and the battery percentage that is shown to us does not correspond to reality. This could lead to, for example, phone blackouts at the least opportune moment and with the user wondering why this happens if there is still more than half of the power left.

That is why it is important to maintain a well-calibrated battery, which is also beneficial in two ways: on the one hand it will allow us to see a reliable percentage, and on the other it will help us maintain an optimal and healthy level of charge for our terminal. This process may seem to have a lot of mystique around it, but the truth is that it is actually quite easy to carry out.

How to calibrate the battery on your Android

Android does not have an official, unified way to calibrate batteries; manufacturers do not give proper official instructions. However, there is a method that we can consider as universal, that we can use with any device regardless of the brand.

The method is the following:

  1. Charge the mobile battery completely and, when it reaches 100%, do not disconnect it immediately. Wait for a while before doing so so that the upper limit of the load does not go out of calibration.
  2. Discharges the battery completely. You can make intensive use of the terminal, wait for it to download by itself, or use games and multimedia applications until the phone turns itself off.
  3. Let the device sit for at least 4 hours, so that all the residual energy that may remain in the battery is released.
  4. Charge the phone back to full power as soon as those 4 hours have passed.
  5. Turn on the phone again and use it normally again.

It is a time-consuming process that requires us to spend a few hours with a replacement terminal or totally disconnected (something that, on the other hand, is not bad for anyone), but very simple. If you want to have your Android battery calibrated, you no longer have an excuse.
