[q] gt-i9000 version 4.1.2
I am having an issue with battery life ,from some reason my device is consuming lot of battery .I have replaced the battery but issue mantained.
I also checked the running application and no strange application is running that might cause exta battery usage.
I wanted to use battery callibrator but as i dont have phone rooted i cant do this step.
I would like to know from people that are expert on this matter what should i do since battery has been changed and no improvement so far.
