When you sleep, does your phone sleep, or does it stay up all night and crunch 1s and 0s? Rate this thread to express how you deem the speed at which the Samsung Galaxy S7 Edge's battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.

Then, drop a comment if you have anything to add!

I had been having an issue where mine was never entering deep sleep. I tracked it to two things. Google voice recognition on every screen and auto backup. Once I turned those off, the battery drain seems much improved, although I only made those changes this afternoon.

If you're having issues you might try to identify the wakelock via ADB. Run the below code in a loop and see what pops up. It worked for me.
adb shell dumpsys power | grep -i partial_wake_lock

That being said, I sure miss having root to run BetterBattery Stats. . . . Sigh. . . .

sorry for the stupid question: does S7 Edge enter deep sleep automatically?

I am having a serious battery drain issue in standby. I did just turn off my google voice recognition on every screen (thanks czucker) so I'll see what happens. Im kinda upset with the performance though. I picked up the phone on Tuesday from my local sprint store (pre-ordered and it came in early) so maybe the phone is still learning my usage patterns but still the standby battery drain is concerning...

Maybe I have the same issue. How could you turn the Google voice recognition and the auto backup off?

I fixed standby drain by turning off NFC and set OneDrive to only upload when charging. Donno if thats your problem, but its my best tips since it worked for me ;)

westerville, oh
In my first full day with the S7 Edge I was not super impressed with the battery. From 7am to 9pm, from a full charge I ended the day around 10% with very minimal. Maybe the large screen takes up more juice than I thought---I was expecting the larger battery to last me quite a bit longer. Coming from the HTC M9 and that battery ended my day around 30%.

Thank you! After a few days usage, still not getting good battery life, usage time is around 11-12 hrs, the battery drain appears to be android system. I've turned off almost all apps from notifications and auto updates. Reading other posts the exynos version is getting great life. The 820 and Android system aren't playing nice...

drained overnight

I fully charged the phone 100% before bed. Next morning, 8 hours later battery down to 12 % with android and screen sharing the usage. Next day I resetted the phone to uninstall all my apps and tried again - still almost same result. Is there anything I can do to investigate this? I have turned off Google Voice and Automatic Backups already - the huge battery is performing worse than the htc one m7 i replaced :(

Any suggestions?

Edit: Should have mentioned - the phone gets untouchable by morning! hot as anything - i guess i should be contacting Samsung

No suggestion. It is best to contact Samsung, as this behavior is not normal. These phones are made to be used, and not for us to turn off almost everything just to get through a day. :)

Thanks for the ADB command. I'm showing "AlpmModeManager" as a "Doze_Wake_Lock" (I modified the grep string a bit because partial wasn't giving any hits)... Any idea what that is?

Had an issue with the "Pocket" app. This awful crap drained almost 10% of my battery and I did not even used it (I did not setup the app and did not opened it.. not even once..). All good after I uninstalled it.

    You will find voice recognition in the Google app under settings/voice/OK Google. The second one is in settings/backup and reset under samsung account.
