It is bone stock - never been rooted. It's running on 2.3.4 GB at the moment. I have completely wiped it and set it to factory default. There are no apps installed, no accounts synced up but the drain continues. I even swapped it with a brand new battery and it still does this. Would anyone happen to know what I can do to fix the issue? The phone does have a few scuffs but it has never been severely dropped or gotten wet. It seems to have just started doing this on it's own.
This is the phone after a 100% charge and full wipe. It put it next to me and did not touch it at all. It was down to 50% after about 4 hours.
