Help samsung galaxy S3

[littleq]

I bought my samsung galaxy S3 about 4 months ago. I noticed 2 weeks ago that my battery drains very quickly at my workplace (within 4-5 hours); there's no issue when I'm at home. I tried different things like shutting off the wifi, taking the battery out for reset, but it doesn't work. Leaving the phone on the charger doesn't help either, the battery still drains. By the time I leave work my phone is completely drained. I don't use or download apps, phone or text usage is very low, I usually answer a couple of calls that are under a minute. I don't have my screen brightness very high, no Bluetooth or anything else on or connected. I've always had my phone with me at work without any issues until recently. My carrier Fido couldn't help other than to ask to drop it off for a few days. I'd prefer avoiding this if I could. Can anyone advise? Thanks!

Have you tried disabling mobile data? Also when you look at the battery stats, theres a colour coded line Just below the graph showing how strong the signal was at a certain time, does it show a weak signal at the time you were at work? Apart from the screen, the radios can be a huge battery chewer in a poor signal area :thumbup:

You can see from my stats im in a terrible area strong would be green

P.s. i would edit the thread title to something like "intermittent battery drain?" Or something since its an s3 forum lol
And welcome to our community :beer::beer:
