S.O. S Battery
Before you jump to any conclusions, check to see if the battery is the main culprit or is it the Android system calibration that has gone bonkers.
How to check for battery problems: Switch off your phone and remove the cover. Get the battery out and examine to see if it is bloated or if you can notice leaks. Of course, there might more severe problems regarding the battery, these being manageable ones. A new firmware upgrade for instance might also be responsible for your battery drainage and the list can go on.
Calibrating a phone: Meaning?
The Android OS has the Battery Stats element included. This helps you see the battery’s capacity, meaning when it is full and when it is empty. When you calibrate your battery, you readjust the information in the Android OS, it’s as simple as that.
Ways and means to calibrate battery with and without root access:
The method without root access for Android device battery:
- Allow your device to be fully discharged.
- Switch it on and allow it to shut down again.
- Use the charger to plug in the Android device, but do not switch it on.
- Remove the charger.
- Switch on the phone. If it doesn’t show 100% charged, keep leaving it to charge so plug it in once more.
- Then pull the plug the restart it. If it still doesn’t show you 100% charged, repeat the whole charging procedure again and keep on repeating it until you see the phone fully charged.
- The next step is to let the battery discharge until it reaches 0% and your phone switches off once more.
- Now you can charge the battery again, but this time around without any other delays. Your battery should definitely be calibrated now.
Important: We do not advise you to perform this action constantly. This should be done every 3 months and make sure you try this if there is no other way, because on the long term your battery will be affected.
