The growing versatility of our gadgets has increased the strain on them considerably more than it did a few years ago, which is a serious concern for Android smartphone owners. Your device’s battery performance can start to decline over time. It is common to observe a minor decline in battery performance with time, but re-calibrating your battery can be helpful if this degradation occurs rapidly and you are certain that the battery is not the issue.
Typically, malfunctioning apps or erratic charging patterns are the cause of this issue. Significant battery depletion is also a recognised side effect of flashing a custom ROM.
What does it mean to calibrate your battery?
The android operating system features a built-in indicator that monitors the amount of charge left in your battery and uses that information to determine when the battery is full or empty.
Sometimes, this data gets messed up and starts giving the inaccurate information since the battery level wasn’t correctly detected. For instance, even with a full charge on the battery, your phone could shut down unexpectedly.
If this occurs, your battery needs to be calibrated immediately. To clear out all false information and for the Android system to start presenting the right facts, battery calibration simply resets your battery stats and creates a new batterystats file.
Before you begin with battery calibration
1. Check if your Battery is the problem
If your battery is removable, remove it to make sure it isn’t swollen or bloated, as those symptoms may point to a broken battery, in which case calibrating will be ineffective. If you discover physical damage to your battery, you must replace it or at the very least, take it to a repair shop for professional advice.
2. Clear cache partition
While installing a custom ROM or updating to a new version of Android, battery drain is a regular issue. Make careful to empty your cache partition before calibrating your battery.
In recovery mode on your device, select Wipe Data/Factory Reset, and then select Wipe Cache Partition.
You can continue with the rest of this tutorial after that is finished.
Calibrate your battery on a non-rooted Android device
Calibration is a manual process that could be a little difficult for Android devices that aren’t rooted.
There is no assurance that it will function, and occasionally, it can end up doing more damage to your battery. Nonetheless, you may choose to take the chance if your battery is seriously malfunctioning.
- Let your phone discharge until it goes off due to low battery.
- Charge your battery until it reads 100%. Do not turn on your device while charging!
- Unplug your charger and turn your phone on.
- Leave it lying for 30 minutes then charge it again for an hour. Don t use your device while it is plugged in.
- Unplug your device and use normally until the battery is completely drained again.
- Then charge it to 100% again.
The steps are as follows:
Calibrate your battery on a rooted Android device
The batterystats file is rested as a result of this step, and your battery should now be calibrated.
- Head over to the Google Play Store and download the Battery Calibration app.
- Launch the application.
- Click the calibrate button. Grant the application root access.
- Reboot your phone and use it normally until it reaches zero percent.
- Charge your phone again until 100%.
- You should have a correct reading from the Android OS now.
The procedure is much easier for users who are rooted. Before beginning, make sure your battery is completely charged:
