Ok so my phone Xperia Play r800i which i bought like 6 months ago. Recently i have some trouble with my battery life, this happened after i replaced my touchscreen (due to damage) and after i've updated the OS to 2.3.4. Before this the battery life is close to 24hours now its less than 10hours with gps, wifi, data traffic, auto sync turned off. I wanted make sure what is the cause of the problem, so i decided to exchange battery with my brother since he also have Xperia Play r800i with OS 2.3.2 which he bought just over a month ago. But i still get a battery life less than 10hours while him using my battery gets close to 24hours. So guys, any idea on what is the cause of this problem? Could it be the replacement screen or the latest OS version or others?
