[Q] Battery draining instantly from 30% to 0
Thanks for looking at this in advance.
Total Droid noob here...I purchased my first android device about 2 weeks ago, a Galaxy S5 on AT&T
Needless to say, I haven't really done much of anything out of the ordinary with it.
I've installed a few official Apps from the Play Store and nothing else. No custom roms, no random apps/packages from the web, etc.
Just today, my phone was sitting idle (asleep) next to me as it always does at my desk. I looked at it to check the battery and it showed about 51%. No issue at all with that...I used to it to read my RSS feeds, listen to Spotify, and a bunch of other things on my way into work.
However, maybe a little over an hour or so, I went back to check on it...and the device was completely off.
0% battery, completely drained...
I was baffled, but this was the second time
I had seen this happen. The first time it I ignored it, figuring I was just drunk or something. But now, I feel like I'm going crazy!
A friend told me to check the 'Battery' info inside Settings.
Granted Instagram was high on that list, using like 14% of battery or whatever...but thats not what struck me. It was the graph depicting the battery use (SEE ATTACHED)
Notice that it went from ~30% to 0 pretty much instantly
Basically, I'm coming on here as a noob with a few questions:
is this normal? is this known? is there a solution? should I return my phone?
Thanks a ton for any help you all can provide.
Please let me know if you need any more information, screenshots, etc.
