Sorry for the noob post, but in the past month or so my S7 Edge has started randomly draining the battery while asleep. The phone gets very hot (i.e., uncomfortable in my pocket) and discharges the battery rapidly (i.e., half the battery in an hour) until I reboot. I suspect a recent software update (AT&T phone running G935U ROM) is causing the battery drain problem as I previously had exceptional battery life. Any suggested fixes to try?

Hi guys, this is not another rant post about battery life, but i'm starting to become really
frustrating with it, i tried almost all the solutions provided here on the forum but i can't
simply get the **** out of it. This is my story:
I bought the phone as used around 1 month ago (the guy who sold me the phone used it for around 1
month as well). I was quite satisfied about the device, but i noticed almost immediately the damn
poor battery life. With stock battery, my stats are (this is an average of the last 3 times i
used it):
Average duration: 27 hours
Average display usage: 2.5 hours
Average display %: around 45%
Average standby: Cell 30%, phone 15-16, other apps and android core 1-2
This with the following configuration:
3g off
gps off
background data off
bluetooth off
display brightness set to the minimum
no background applications or live wallpapers
No animations
No vibration feedback
No sounds
No widgets
Removed 5 touchwiz panels out of 7
Wi fi on (actually i noticed some small improvements by leaving it off)
The strange thing is, i noticed that the phone drains a LOT of battery while in standby. During
the night (7-8 hrs standby) my phone can drains up to 20% of the battery life. I read on the
forum that a lot of you guys have a battery drain overnight of around 2-3% which is 10 times
lower than mine.
So i thought about 2 possible causes:
1) Software related(processes or applications running in background)
2) Hardware related (battery ****ed up by the previous owner; phone not going in standby correctly)
Regarding the problem 1) i tried almost every solution provided here on the forum. Updated to new roms (JM5 and JM8) installed ultraslim roms, installed battery saving applications and task killers, performed some exotic "fixes" (removed battery stats file, tried to completely drain the battery following some procedures explained here on the forum). Nothing helped. To check case 2) i bought a cameronsino extended battery. Well with this battery i have exactly twice the duration of the stock battery. Last night i charged it to full before going to bed. This morning, when i woke up, the phone drained 10% (!) of the battery in 8 hours. So the stock battery is not the problem. What should i think then? that My phone is ****ed up? is There no chance to obtain a decent battery life? How is possible that a lot of guys have almost twice my battery life with stock battery?
I guess your phone may not be going into the sleep mode correctly ... try using system panel (from the market) and figure out which rogue app is causing the problem. Mine usually drains 4-5% at night.. (jm8 stock + voodoo)...
My LG G2 (verizon) turns itself off and will not turn back on when the battery reaches 40% capacity (or sometimes in the 20 to 30% range). When I plug it into the charger, I am turn it on and use it again, and it indicates that the battery is not fully depleted. It also seems like the battery is depleting more quickly than usual during use (web browsing).
In short, the phone behaves like the battery is dead, while indicating that it still has a significant charge left.
Are there any tests I can run to identify the problem? Or other troubleshooting tips to resolve the issue? Thanks for your help.
Battery most likely busted. Abnormal reading of the battery is a common symptom. Had it before on a HTC one..
This problem coincides with the installation of the new Lollipop OS also.
I started the upgrade, then realized it was 640MB and I wasn't on wifi, so I cancelled it. The problem started around then. I have since completed the upgrade with no improvement in the battery issue.
Hi guys,
I have some trouble with very differing battery discharge behavior, because of unknown reasons.
For example today: in the afternoon, the phone was lying on my desk, in Standby (you know, black screen, but switched on). After a while I grabbed it and noticed that it was quite warm. And indeed, the battery had lost way more than normal during a short period of time. I shut it down completely to save some capacity for the evening.
I turned it on 45 minutes later only to see that it had lost a significant amount of capacity while shut down/turned off!!
Sooo:
1. Has anybody experienced something similar?
2. Is there an explanation apart from a very crappy battery (but usually, it does not seem to be one) or a spy software running?
Regards,
Puni
I know I had another post about my horrible battery life, however I was able to finally resolve that. This time however I have a new issue with it that just started a few days ago so I figured I would make a separate post.
I will say, on a side note, I'm super close to crushing my Turbo 2 in a bench vise at this point, Motorola and Verizon are quickly getting themselves to the top of my **** list......
I'm having an issue with a wakelock by the name of "ConnectivityService" that is keeping the phone awake and causing the "Android System" to be at the top of my battery drain list at 70%. This only seems to start draining the battery when I'm not connected to wifi. If I shut off wifi completely it gets worse.
Connectivity Service is holding the phone awake constantly and draining my battery down completely in just a few hours. I can't seem to figure out if there is an app or setting that can disable that wakelock, but I haven't installed anything new lately and there haven't been any app updates that I have seen.
The other issue is when I restart my phone, the battery level drops by 10% every time.
And for what its worth, with my past battery post "fix" I was only able to increase my battery to last around 20 hours on a single charge with 1.5 hours of screen on time. Still not great but this new issue is pretty much rendering the phone useless.
Any suggestions or should I put a deer slug through this phone?
Hi there.
I got this 2nd hand Note 3 (N9005) last week, and I'm testing battery life in different conditions with the original top update (5.0), before I flash a custom ROM and use it as my main phone.
System says battery is in good condition, and it has a fairly good standby time, but it drains quite fast (about 1% per minute) when active / SOT. GS monitor says I'm averaging 1h46m SOT, which I know is not good, and understandable since I guess this is the original battery.
Now the weird thing: I had about 13% battery when I turned it off. I removed the battery (I needed to take out the SIM card, I don't think this is related) but when I put the battery again in and turned it on, I had 35%!
I spent all of that until it has below 3%, it sounded the alarm and completely dimmed the screen and so, then I removed again the battery (checked also the contacts, nothing dirty on the battery or phone btw).
When I put again the battery, I got 18% power left. Now it's gone and I am afraid to play this game anymore - I'll just give it a full charge.
Does anyone experienced similar behavior? I wonder if it's a calibration problem, or a known symptom for old batteries.
As a side note, I had a Note 3 Neo Duos last year and the battery was bad. It used to discharge almost instantly from 30% to zero and turned off the phone. However I remember that I could remove and put again the battery for some extra life, just the same. I'm more or less terrified by this lol.
(The Neo Duos, N7502, was stuck at 4.3 without any development. I'm glad I was able to get this N9005 now).
I'm attaching a GS mon. screenshot showing usage so far, and the system Battery Use that shows the two points when I removed the battery.
Difficult to follow your post.
Suggest as first step Wipe Battery stats.bin.
Or from play store battery calibration app to wipe battery stats.
This will not calibrate battery just reset battery stats.
