Battery life suddenly dropping ( HELP )
My battery life have suddenly drop by around 10% over the night, its not because of any apps that I've installed or used. I've look into google and there's a website from thetecnica saying about calibrating battery using an app. Sorry I can't post links since I've just registered for this forum.
The reviews are good but I'm still not sure whether to use the app to fix / repair my battery problem. Hope anyone can give me some opinions or help
( Notice the image below, the battery graph at the middle has gone downhill straight, around 10% )
