Searched through the forum for discussions regarding battery drain, and there are quite a few, but none of those I found regards battery drain when the phone is OFF.
7% during one short night, which is way over the rate of battery drain when it's idle (i don't have a sim in it right now).. First I thought that I simply forgot to turn it off, but then it happened several times. And then when I start charging it takes a while before the battery starts giving signs of life, like it's been severely depleted.
Anyone having similar experience? I haven't really tried any solutions since I don't have any ideas. Similar thing happened to me once before when I used an old Samsung tablet and nothing I did seemed to make a difference so I had to get rid of it eventually. I sincerely hope there is something to be done here. Any ideas will be greatly appreciated!
