Battery Drains Quickly Even When Not In Use

W

WPCentral Question

I Have a lumia 520. My usage is light. I charge the battery fully to 100% before going to sleep and all background apps and wifi and mobile data are switched off. but by the time i wake up (about 8-9 hrs later) the battery level is down to around 60% without any usage. I have been struggling with this problem for months and even visited nokia care 6 times in between. They Changed the battery the first time,but to no use. Later a couple of times the phone worked fine for a couple of charge cycles before the problem cropped up again. what to do? please help
really feel like trashing my phone in the bin.

How long have you had the phone? Did you turn off all the background services? I'm assuming you don't have 8.1 or Cyan yet?

I have had the phone for about 8 months. It worked ok for first 4 months before it started acting up. No,i dont have 8.1 Dp installed. I think the problem started a few days after black update.

Hmm it might be because of Black.. 8.1 will stabilize the battery

Try a battery app to see the drainage :) Also do you leave the wifi on when you sleep? try sleeping with flight mode on
