Android devices have always been about raw power. Since the explosion of handheld technology, it has helped push the limits of processing power. This frantic race towards more CPU-GPU performance and higher screen resolutions has helped us reach the point where smartphones are no longer the poorer brothers of their larger counterparts. But in the long run, we were also faced with one of our essential requirements: the battery. Although the devices have grown, the waist size also had to reach remarkably low dimensions! And to get the most out of your battery, you may need to calibrate the battery on Android for better performance.

Well, we all know that the battery life should be an aspect supported by device manufacturers from the very beginning.

We know that device manufacturers have made great efforts to incorporate larger batteries into the devices this year, and some of them are certainly compelling in terms of time of use. Android Pie could also make some tweaks to change things, but let's be honest, we need to get by without the Nougat and Oreo devices that have made significant changes to Android battery management. Enough comment, let's get to the point.

What is the calibration of the battery

What do we mean by calibrating the battery of your device? Well, Android has a built-in battery indicator in the settings menu. This feature allows the operating system to keep track of your device's current battery level.

Sometimes, if the battery is not calibrated, it may cause incorrect statistics on your operating system's battery due to incorrect battery level detection. You may be wondering how it will hurt. Incorrect battery level detection can cause your operating system to recognize that your battery is empty and shut down your device, even if it actually has 5% battery left. Is it convincing enough?

In fact, in many cases, users have experienced a sudden drop in battery level, even though it has been stable for some time (for example, the battery level has suddenly dropped from 60% to 30% ). 40%). This can happen because the custom ROM installation has ruined your batterystats file.
