Battery life is an important concern for users of smart phones with Android and the greater versatility of our devices has made the demand on them much higher than it was only a few years ago. After a while, you may notice a decrease in the battery performance of your device. It is normal to notice a slight one in the performance of the battery over time, but if this deterioration occurs drastically and you are sure that the battery itself is not the problem, the recalibration of the battery can help.
This problem usually arises due to irregular load patterns or misbehaving applications. Flashing a custom ROM is also a known cause of drastic battery depletion.
What does it mean to calibrate your battery?
The Android system has a built-in indicator that tracks the level of charge remaining in the battery and this is how it is known when it is full or cow.
Sometimes, this data gets corrupted and begins to show incorrect information due to an incorrect detection of the battery level. For example, your phone may suddenly turn off when there is still a substantial charge in your battery.
If this happens, you definitely need to calibrate your battery. What the battery calibration does is simply reset the battery statistics and generate a new batterystats file to clean all the false information and make the Android system start displaying the correct data.
Before starting the battery calibration
1. Check if your battery is the problem
If you have a removable battery, remove it and check if it is swollen or swollen, as that may indicate a damaged battery that, in that case, the calibration will make no difference. You should replace your battery if you find physical damage or at least take it to a repair shop to get the opinion of experts.
2. Delete the cache partition
The download of the battery is a common complaint when you upgrade to a new version of Android or update a custom ROM. Before calibrating the battery, be sure to erase your cache partition.
To do this, restart your device in recovery mode, scroll to " Clear data / Reset factory settings "and click on the option" Clean cache partition ".
Once this is done, you can continue with the rest of this tutorial.
