Hi All,
We have two S7 Edge units - 1 from T-Mobile the other from AT&T. Both are having a battery drain issue.
It seems Android Kernel and Android System are draining the battery constantly. The phone doesn't seem to be falling into deep sleep either.
Average rate of battery drain is 7-10%/hr while idle (screen-off).
The T-Mobile phone has the "U Firmware" installed.
The AT&T Phone is stock with the latest OTA installed.
I've attached the GSam statistics here:

Note: I've tried the following
Disable Wi-Fi, Bluetooth, Location, NFC
Disable Google Backup
Disable Wi-Fi and Bluetooth Scanning (Location Services)
Updating Play Store & Galaxy Store Applications
Removing unnecessary applications
Clearing Cache partition from Recovery
Rebooting 3 times simultaneously

I'm using the latest Xtrestolite ROM with stock kernel, and I'm experiencing considerable battery drains and wakelocks when using the airplane mode.

I think Google Services is the one causing wakelocks, but WLD shows Cloudmagic despite it being one of the best behaved apps. My location reporting is turned off, locations services set to GPS only, and WIFI scanning even when off is also turned off. Please help me fix this issue.

I recently bought a used T-mobile Samsung Galaxy S5. It came running lollipop. The battery has been awful. I lose around 50% a day without using it at all. I frequently pull my phone out of my pocket during the day, and it will be hot and the screen will be on. When it is in airplane mode the battery life is normal, and there are no problems. I have tried resetting it, clearing the cache, greenify, and multiple battery saving apps. Nothing helps. Any suggestions?
Install a battery monitoring app, see what's causing it
Most likely due to certain apps you have installed that are draining your battery (maybe try rebooting into safe mode and see if the issues persist) Then use BetterBatteryStats or something similar and see which apps are causing it
Hello,
I'm on stock rooted 6.0.1 and I recently noticed that my battery life has been terrible while on cellular data. I installed wakelock detector as well as better battery stats and both of them point to ssp_sensorhub_wake_lock as the culprit for keeping my phone awake constantly while not connected to wifi. As soon as I re-connect to wifi, my phone sleeps normally and my battery life is great. I used titanium backup to freeze most of the samsung system apps without any luck.
Does anyone have an idea as to what would be causing this? My phone is SM-G900R4.
It happened a few weeks ago and has not improved. After the most recent update, I'm getting anywhere from 15 - 50% battery usage from Play Services.; my usual play services battery usage is 1 - 3%. I'm on the latest version, and apparently it's affecting devices from all different manufacturers. It's not heating my phone up and it still says it's deep sleeping, which leads me to believe it's messing with hardware - constantly scanning wifi or bluetooth or something. CPU usage isn't any higher than normal. If I leave my phone unlugged while I sleep, it'll drain 25+% battery over 8hrs while it claims it was in deep sleep the whole time.
I can't roll back or remove play services (I'm rooted and on Oreo), I'm about to try clean flashing my ROM with no gapps, and installing an older version of play services. I don't know what to do, I'm just wondering if anyone here has had the issue or found a way to stop it.
edit: I ended up clean flashing my ROM with the latest opengapps and it seems to have stopped killing my battery.
I tried more than 1 Rom and the problem exists, while screen is on battery usage is normal, while screen is off its huge.
Phone enters deepsleep just fine, it's not awake.
Could it be faulty battery? Or something else?
You could do with Gsam battery monitor to see what apps are causing this battery usage. If I were you I'd stop all weird Google location logging activities such as location history and unnecessary device syncing and also look at all samsung related apps as most of them have cloud connectivity which is enabled by default. I have recently been through this exercise and have my standby drain to an absolute minimum now.
Also, if you are on cellular as opposed to Wi-Fi, disable 4g unless you are doing something that specifically needs 4g data speeds. 4g connectivity appears to be a big battery drain on any phone.
