Just got the S7E AT&T variant yesterday afternoon. I too am seeing high battery drain on Android System. 31%. I don't want to be too quick to judge battery life because I have the new phone syndrome right now. But, coming from an iPhone 6s Plus I can already tell the battery life on this phone isn't as good despite a significantly larger battery. I'm a fan of both OS, IOS and Android. I also own a Nexus 6p and Android System battery drain is NOT an issue. The common denominator here is Samsung and TouchWiz which I've always hated. What drew me to the phone was the Camera, big battery, build and screen. But, once again, so far, I am not all that impressed. Ah, well, at least I have 14 days to return it. We'll see.
[Samsung Galaxy S7 Edge Questions and Answers] laureanop:
The issues here is not Samsung or Tw! It's the snapdragon chipset! I'm confident an update from Qualcomm or Samsung will take care of it
[Samsung Galaxy S7 Edge Questions and Answers] theneighbor:
What makes you so sure that's the case?
[Samsung Galaxy S7 Edge Questions and Answers] FalconFX:
Its definetly the SD chpiset that's at fault here, since all carriers have the Android OS issue, so its not limited to 1 or 2 carriere phones, The part about the fix im not so sure, Samsung have already dispatched an OTA to exynos version worldwide, but nothing for the SD version. but ine can hope :)
[Samsung Galaxy S7 Edge Questions and Answers] supercakefish:
I have Exynos but haven't received any OTA update? Well, there was one but it was only ~1MB and served to remove Samsung Pay from there phone and seemingly do nothing else.
[Samsung Galaxy S7 Edge Questions and Answers] FalconFX:
Where are you from, there was one that was sent out on the 11th, it was around 60mbs, where are you from ???
[Samsung Galaxy S7 Edge Questions and Answers] supercakefish:
UK. My software version is G930FXXU1APAW.
[Samsung Galaxy S7 Edge Questions and Answers] FalconFX:
You are using the flat S7, i was talking about the Edge.
[Samsung Galaxy S7 Edge Questions and Answers] supercakefish:
Oh right, is the update not available for flat S7 too?
[Samsung Galaxy S7 Edge Questions and Answers] FalconFX:
They released an update on the 11th, but none to the uk
[Samsung Galaxy S7 Edge Questions and Answers] supercakefish:
Ah OK, maybe ours will come next week. Or maybe it was specific to a certain region.

How tf are you guys getting 1 day 12 hour estimates????? I'm lucky if mine says 11 hours
[Samsung Galaxy S7 Edge Questions and Answers] duggerdean:
I really hope this is fixed soon. I'm about to return it within my 14 day window. I haven't been able to get better than 10hrs. I see these people pulling 1 day+ and it is so frustrating.
[Samsung Galaxy S7 Edge Questions and Answers] mjs2011:
I will say this. Even with the issue I am averaging close to six hours of screen on time per day. I've simply never achieved this with an android phone before. So if this is fixed imagine what the screen on time will be.
[Samsung Galaxy S7 Edge Questions and Answers] Zanr Zij:
I can get more sot (7h) with my Note 5 so I expect more with S7E because of more 600mAh batter + smaller screen

I have IMS service, IMS settings and IMS logger disabled and no errors with that.

Ok i think i found something. I have installed bbs to see whats killing the battery and found out it was a kernel wakelock. 2 to be exact. The first one was the ssp_wakelock the 2nd one was wlan . Wlan is related to wifi router being badely configured. The first one os related to sensors i think and to check this, i went to special features and found that all smart things are on after flashing the new fw. I always disabled them but theyre on by default. I disabled everything except the smart palm swipe for screenshots and the ssp_wakelock is down a bit but it's still high and account for 10pct of the kernel wakelocks which are 90% of my tital wakelocks
[Samsung Galaxy S7 Edge Questions and Answers] Eran Says:
Just FYI you can take a screen shot by concurrently pressing the home and power buttons so you could turn off the palm swipe if you want.

I WAS Experiencing the drain but switching to 2,4ghz wifi fixed it the 5ghz driver is broken 5m away from my router and he was dropping signal (unstructured) my screen off time was 15min=-1% box I am 1,5h and not dropped 1%
[Samsung Galaxy S7 Edge Questions and Answers] anibalhuneeus:
So guys has anyone been able to see of this issue has been corrected on the APE9 base?
[Samsung Galaxy S7 Edge Questions and Answers] jgodfrey82:
So I used to never see Google play services in battery usage, I had run the gservicefix app anyways and now it's top of the battery drain list... anyway to reserve this process? Is it really now eating more battery or just displaying differently than before? I need another day to see what I'm getting for SOT as I haven't charged normally the last day or two.
[Samsung Galaxy S7 Edge Questions and Answers] macke909:
Wifi drain...

I can confirm that something is wrong with WiFi. I went 12h today with no WiFi and moderate usage. Some Netflix and Spotify etc. Still have 77%. Usually I only have like 50 or less.
[Samsung Galaxy S7 Edge Questions and Answers] anibalhuneeus:
Firmware?
[Samsung Galaxy S7 Edge Questions and Answers] seanie2322:
According to Gsam my phone radio is always on even with data disabled. Is this normal? On old firmware I downgraded after having problems with the April update
[Samsung Galaxy S7 Edge Questions and Answers] Cholek3:
That's funny. I also have problems with my WiFi 5GHz. But my router recently started playing up and I thought it was because of that. I will compare it with my old Note 3. I am on BTU/XEU firmware APD1.
[Samsung Galaxy S7 Edge Questions and Answers] gyoung:
YES. I can confirm that in APE9, there is no more wifi drain.

Longer standby time. Similar SOT
[Samsung Galaxy S7 Edge Questions and Answers] anibalhuneeus:
Great thank you

How much SOT are you getting?
[Samsung Galaxy S7 Edge Questions and Answers] gyoung:
4-5 hours

edit: I have never drained my battery completely to test my SOT but it's about 4h with about 15-20% left. I guess the remaining juice can last extra 1-1.5h.
[Samsung Galaxy S7 Edge Questions and Answers] bailyc:
Even with data disabled, you'd still receive calls and texts. It's just a basic phone. So the radio is still on, unless you use airplane mode or disable mobile network.
[Samsung Galaxy S7 Edge Questions and Answers] mrhizzo:
Which region (CSC) already have the APE9 firmware?

Thanks.
[Samsung Galaxy S7 Edge Questions and Answers] Cst79:

so IT IS solved :D !
[Samsung Galaxy S7 Edge Questions and Answers] Xatanu:
I have been experiencing high battery drain since I installed APD1, but after upgrading to APE9 it seems to be corrected since I'm getting again 8-9h of SOT.
[Samsung Galaxy S7 Edge Questions and Answers] Cst79:
With Android System at 15%, whereas until APD1 it was at 3-4%, it doesn't look like solved to me. The Android System drain affects the stand-by time much more than the SOT, since it is a constant background drain. This phone should be capable of 48+ hours of stand-by with 6h SOT, on a mixed 4G + Wi-Fi usage, with no package disabler used.

Maybe there are some optimizations, but I suspect Samsung is never going to solve this as the additional drain is probably needed for some stuff, and they just "optimized" their initial firmwares in order to look good in battery life benchmarks.

This is what I would expect from a "fixed" firmware, regarding Android System drain:
[Samsung Galaxy S7 Edge Questions and Answers] anibalhuneeus:
Which firmware would that be? (48+ hours and 6 hours SoT?)

Thanks!
[Samsung Galaxy S7 Edge Questions and Answers] alexdiaz:
Every firmware pre APD1 on Exynos had way better stand-by time.

APE9 doesn't seem to fix this. Maybe Samsung realised and that's why they are delaying the updates for Exynos.

[Samsung Galaxy S7 Edge Questions and Answers] wrexed03:
Hi all im also experiencing high battery drain. Lucky to get 12 hours of usage on the phone was hopping i would get 2 days out of it.

When i bought the phone i ran the software updates after i set it up and it took me to the latest APD1. Afterwards I stumbled upon this post re battery drain.

Im thinking of rolling back to APC8 even though Samsung fixed other bugs in the later current release.

My concerns are using odin and loading the firmware from sammobile and triping knox.

Also can we load older firmware without any functional side affects eg boot loops etc and bricking the phone.

Any input would be greatly appreciated.

Regards
[Samsung Galaxy S7 Edge Questions and Answers] seanie2322:
Once you download the correct firmware version for your device and flash it through odin you should have no problems and you will not trip knox

Does anyone know what causes the "radio-interface" wakelock? My battery life has been much better overall, but whenever this wakelock goes haywire periodically, it kills my battery life.
[Samsung Galaxy S7 Edge Questions and Answers] saketkutta:
Anyone still having battery issues just after charging, see if turning off Google backup fixes it. I think it fixed mine.
[Samsung Galaxy S7 Edge Questions and Answers] sicutero:
fixed mine also.

at least i don't have to remember every morning to restart the phone, it started to become a hassle.

I will just turn it on, once a week to do its work and turn it off again.

it's a pity, such an amazing phone and suffering from something stupid like this.

is Samsung even aware about this issue ?
[Samsung Galaxy S7 Edge Questions and Answers] L4s7Re4lG4mer:
So what is the fix you apllied to get it fix
[Samsung Galaxy S7 Edge Questions and Answers] Cholek3:
[MENTION=3652663]sicutero[/MENTION]

I know it is not a solution, but do you know you can set a phone to restart a phone every day at specific time in phone settings?

In theory the solution is to turn Google backup back on for few hours once a week to do its job, then remember to turn it off. Could use some sort of automated feature for that. Maybe there is an app to do that? If MM allows to change that state (on/off).

It is not the google backup trust me
[Samsung Galaxy S7 Edge Questions and Answers] Calculator_SG:
Ok thanks.

I think is just Samsung software.

Its always the same.

Usually i don't have android OS at first but today don't know why i have it even with 1.3h sot. 80%
[Samsung Galaxy S7 Edge Questions and Answers] wrexed03:
Just an update i installed APC8 and Android system is sitting at 15percent. Will let things settle down and run with this version for now.

Thank you previous poster for your input
[Samsung Galaxy S7 Edge Questions and Answers] sicutero:
Google backup off and android system is sitting all day at 11%, so something is going on there.

Maybe it's Samsung SW vs Google SW, i don't know, but it is an issue and most of us are suffering from it.
[Samsung Galaxy S7 Edge Questions and Answers] SEVENEDGE:
First time, as far as I know, I suffered this drain bug. I did the Verizon disable thing thread, and it really did help. So I charged my phone, unplugged and saw the battery drained more than normal. It was awake for 3 hours!!! Google services I think. I'm on stock, Verizon May Update, SD820.

I check in other thread that 935T can restrict the background data, on Google services but in the 935F it can't.

Mine was working superfine. Then i recently installed few more apps and games from playstore and messed up. Removing the apps didnt help.
[Samsung Galaxy S7 Edge Questions and Answers] cavags5:
Today android OS is on the top of the list, but i notice when the signal is good it stops going up
[Samsung Galaxy S7 Edge Questions and Answers] Cinco5:
Mine is definitely caused by Bluetooth.

I've got all of the location/finding/auto-connecting stuff off, and with BT on (connected or not) I burn 5-7%/hr. With BT off, 1% or less.

I was thinking of maybe trying to install a different bluetooth APK, but none have worked so far.
[Samsung Galaxy S7 Edge Questions and Answers] hp79:
I had Bluetooth causing major drain at one point on my Verizon S7 Edge. I don't know what exactly fixed it though.

I have a LG G Watch connected all the time. Some time ago I noticed the pairing has been lost with the phone when I checked in Android Wear and also on my watch. I had to remove and reinstall Android Wear. Then I also made sure the Nearby Device scanning in the Settings is disabled. Finally, I used Package Disabler to disable "Nearby devices (com.samsung.android.nearby.mediaserver)" and "Nearby Service (com.damsung.android.allshare.service.mediashare)". I don't understand why Samsung insist on putting so much junk on these phones.
[Samsung Galaxy S7 Edge Questions and Answers] Cinco5:
I'll try disabling those two packages and see what happens. I wish I had a watch or something else to blame. I'm using the same devices that worked just fine with my S5...

Thanks, I'll update after I figure it out if this helps.
[Samsung Galaxy S7 Edge Questions and Answers] saketkutta:
Mine was Google backup as far as I can tell and also from the explanation given by one of the posters making me want to try that option. Plus I installed Gservicefix maybe it did something too.

Can you please be more specific?

What version of s7? Exynos?

What version of update do you have?

How long have you had the new update?

How much battery compsumption does android system en android OS take?

Define normal battery? 1 day? 2 days?
[Samsung Galaxy S7 Edge Questions and Answers] quarintus:
So, I tried installing the firmware again using smartswitch software, so not using the OTA, and just a fresh install.

Don't think it'll work because others haven't gotten better results. If there is a difference I'll post it.
[Samsung Galaxy S7 Edge Questions and Answers] SEVENEDGE:
Guys, try this. Through the app manager, clear the data of each app you want to disable, then individually restrict background data, and then disable. Reset the phone and see it goes from there. Also, try not using package pro disabler. Here are my stats.

Stock Verizon with May update.

I have found the problem to become active after charging the unit. Now I do a restart after charging and the problem with battery drain no longer happens. I guess Samsung have to fix this at some point, but I have managed to avoid disabling every useful feature by doing a restart after charging.
[Samsung Galaxy S7 Edge Questions and Answers] ssgunner20:
For me i feel restarting wastes about 2%-3% of battery life.
[Samsung Galaxy S7 Edge Questions and Answers] saketkutta:

[Samsung Galaxy S7 Edge Questions and Answers] drmrahul:
Sorry guys am mistaken. Even though battery drain is not as severe as before,I lost 15 percent yesterday night on airplane mode for 6.5 hrs
[Samsung Galaxy S7 Edge Questions and Answers] quarintus:
Ok, so installing the firmware using other means, has no change.

Tried this already, But it doesn't work. Yes it saves some batttery, but doesn't cut out the excessive drain. Also, american models should have been fixed with the latest updates. It are now the exynos models that are experiencing the drain.

partly true, but it probably is mainly just the percentage number that changes, not so much the actual energy use. Also, the first few percentages go of the fastest. So it's not that big a deal, especially since there is nog better solution.

People call this a fix, but all it does is bring the percentage of android system down a bit. But not enough. it was possible to get 7 tot 8 h's screen on time with almost 2 days of use. It helps a bit, but it certainly isn't a total problem. My battery is stil lasting just a workday, with google backup disabled. Only some improvement, no fix.

Yes I tried. batterylife seemed to be a little longer, but that's probably because slower charging is more efficient. the bug is still there. Stil high Android system drain..
[Samsung Galaxy S7 Edge Questions and Answers] cavags5:
Just a theory test 2 days with package Disabler and contribute to higher Android System.

And i charge the phone on when its 100 turn off leave it 5 minutes more then restart.

No problem losing nothing.
[Samsung Galaxy S7 Edge Questions and Answers] saketkutta:
Then try gservicefix, maybe it was combo of disabling Google backup and installing it that Android system does not keep my phone awake and use all the battery. And it idles like it's supposed to.

Same here
[Samsung Galaxy S7 Edge Questions and Answers] MickyMax:
I do not see any improvement when doing that.

But package Disabler don't help in noting.

I already test it in all ways.

I found that stopping the GATTService under Bluetooth Share solved all of my battery drain issues. I lose about 1%/hr now, and the phone dozes regularly now. Down from 4-5%

To stop the service, enable developer mode, then stop the service. I've seen no ill-effects with bluetooth, however I only use it in my car.
[Samsung Galaxy S7 Edge Questions and Answers] Cst79:
What percentage is the Android System drain ? If over around 12%, problem is not solved.
[Samsung Galaxy S7 Edge Questions and Answers] anibalhuneeus:
I've read a lot about this issue, and it seems to me that the only way to solve this is by flashing stock firmware from March or before (not APD1 base, which messed up everything) like APC8 from the UK

Do you guys agree?

Also it seems APE9 (the newest update) still has this problem...
[Samsung Galaxy S7 Edge Questions and Answers] Cinco5:
Android System is at 16%, Android OS is at 13%. The phone's been mostly dozing in my car today.
[Samsung Galaxy S7 Edge Questions and Answers] Naemion:
Before jumping to conclusions because it is at 16 and not 12, what all have you been using your phone for and what is your battery at?
[Samsung Galaxy S7 Edge Questions and Answers] Cinco5:
I pulled my phone off the charger at 6AM, and listened to Google Music in my car on my way to work. Phone sat in my car from 7AM to 4PM. When I got in the car, it was at 89%. Since then, I've been redditing, reading news, listening to music (over Bluetooth), texting, etc. and this is what I'm at now.

Trying to attach photos. Let me know if they dont work.

I killed the GATTService more than 48 hours ago, and since then, my battery drain has dropped from 5-7%/hr to 1%/hr.

Not saying this is the cure for everyone, but it's fixed my problems.
[Samsung Galaxy S7 Edge Questions and Answers] Cst79:
Mine is always at 3-4% maximum, on the APC8 firmware.

Here is a screenshot from right now. Look at the predicted remaining stand-by time of 40h, combined with the 14h stand-by until now:
