I've had a pretty bad battery drain issue on this phone and I literally just got it and froze all Samsung bloatware.

I had about 77% at night and in the morning I was down in the 20%. I have no idea what is draining my battery

I didnt think that Display Always on might effect the battery bc of the Amoled screen but tonight is going to be my first night with it completely off. Let's see how it goes.
[Samsung Galaxy S7 Edge Real Life Review] GoMoeJoe:
I call BS !

0% drain over 8 hours with cell radio enabled is impossible.
[Samsung Galaxy S7 Edge Real Life Review] HoTdiGiTi:
Hi guys, I've had my Exynos version Galaxy S7 Edge since it launched over here in the UK and everything was great apart from some silly sound issues when streaming videos.

So after some debating I decided to reset the phone in recovery mode and see if it sorted it out (it didnt).

Now I have a battery drain issue where the android system is using over 50% of the battery. I'm having to charge twice a day now, whereas originally I got a full day of heavy usage with 20-30% batter remaining. Now something on the Android system is using the CPU constantly.

Any advice appreciated, I'm gonna see about rooting and flashing another ROM this weekend when I've had a chance to read up on it.

Thanks

Disable wifi scanning and switch to 3g/2g auto if you have bad lte reception.
[Samsung Galaxy S7 Edge Real Life Review] Pet1981:
A drop of 2% over 6 hours. (Wifi on, AOD off, received FB messages, sms...so LED was blinking 3-4 hours)
[Samsung Galaxy S7 Edge Real Life Review] joeyac02:
Mine dropped 10% in 8 hours Standbye. But yet I still average 2 full days on a charge. Could be better if I figure out why its not deep sleeping
[Samsung Galaxy S7 Edge Real Life Review] HoTdiGiTi:
Ended up wiping the cache and resetting again in recovery mode and its now back to the way it used to be, anyone having battery drain issues i'd suggest just doing that as my android system battery usage is down to 14% now from 51% before. I don't know why it did it. All good now
[Samsung Galaxy S7 Edge Real Life Review] stone0504:
i feel my s7edge (8890) battery getting worse after the latest update (July security update) and get more heat.

does anyone has the same feeling?
[Samsung Galaxy S7 Edge Real Life Review] jddoggett:
Phone's been used a little bit since 6am mostly idle, it's now 8:15pm and it has 90%, I'm calling that damn good. Finally something positive.
[Samsung Galaxy S7 Edge Real Life Review] Shyuura:
Yes I have the same issue, used to have a 2% battery drain overnight but after the last July update it's mostly 5% - 6% with very poor network signal reception. Tried wiping and factory resetting multiple time and even airplane mode, but to no avail :/
[Samsung Galaxy S7 Edge Real Life Review] abachhan75:
yes,, after July update, i have also observed higher battery drain than before. It used to be just 3 to 4% drain during night time, now it is around 10%.
[Samsung Galaxy S7 Edge Real Life Review] meboy:
Welcome to the MM android system/os battery drain club.

Once a member, you're in for life.

At least on other phones you can go back to 5.1.1. There is no for sure fix on MM.
[Samsung Galaxy S7 Edge Real Life Review] dragunbayne:
Mine has also, but I think I know why. Looks like we got carrier IQ. I've got big wakelocks from diagnostics.client.wakelock.
[Samsung Galaxy S7 Edge Real Life Review] dragunbayne:
I stopped the IQService using Service Disabler and my standby wakelocks went back under control. I am on the AT&T variant, so this may not be the case for all. My overnight standby was a little less than 1% per hour using AOD. I find this to be extremely acceptable, in fact it's the best standby time I've ever had on a phone.
[Samsung Galaxy S7 Edge Real Life Review] mettleh3d:
I do not see Service Disabler in play store. Disable Service? Root required?
[Samsung Galaxy S7 Edge Real Life Review] cavags5:
I really sometimes dont know what's going on with the phone, after flash a lot of different stock roms, the last i flash was XSA Australia ACP8 then update to the last update APGH usually all firmwares in 4G android OS always get high. And today i don't know if was the 2h of phone calls i had the best standby in 4G ever, and Android OS was stable. Coud be the doze is working well.

I didn't know but XSA is like BTU its a clean CSC. I could say its a little better than APGI brazil.
[Samsung Galaxy S7 Edge Real Life Review] skinza:
Could be the new baseband

---------- Post added at 05:46 AM ---------- Previous post was at 05:45 AM ----------

Yer you need root
[Samsung Galaxy S7 Edge Real Life Review] cavags5:
Yes coud be , but im liking more the XSA than the newest ITV, standby is good too but in wifi android system is higher in ITV.
[Samsung Galaxy S7 Edge Real Life Review] dragunbayne:
Yes, that is the one!
[Samsung Galaxy S7 Edge Real Life Review] cavags5:
2% in 8h wifi 4G off.

---------- Post added at 09:11 AM ---------- Previous post was at 09:10 AM ----------
[Samsung Galaxy S7 Edge Real Life Review] meboy:
Yes. The drain has been linked to WiFi.

Not sure what your point is. Turning off all radios and not using it is.. Efficient?
[Samsung Galaxy S7 Edge Real Life Review] cavags5:
Well , there is people who drain a lot with everything off, and for stock is good.

But with this rom with wifi on is not much worse maybe more 1%.

Maybe this rom doze works good.
[Samsung Galaxy S7 Edge Real Life Review] meboy:
What rom?
[Samsung Galaxy S7 Edge Real Life Review] cavags5:
Its XSA Australia for 935F i see you have the Snapdragon its not compatible
[Samsung Galaxy S7 Edge Real Life Review] skinza:
Bph6 is slightly better battery for me

With sot and standby

With apgh 4% drain over 8hr and 56m sot for first 10%

Bph6 2% drain over 8hr and 1h2m sot for first 10%

All on 4g
[Samsung Galaxy S7 Edge Real Life Review] cavags5:
Thats good , but at home i use wifi and usually charge every day , but for me prefer APGH , and the minutes you have difference, just a app or brightness coud make that difference.

This rom with wifi and 4G mix android system is 12% android OS 5%,

Now stay here until comes out more updates,.

And CSC XSA us more clean and can always optimise Facebook.
[Samsung Galaxy S7 Edge Real Life Review] traneupcqk:
I lost 4% in 7 hours with everything off :(

Even if i turn on Wi-fi (with location, no AOD, sync) , i still lose the same amount of battery when the wifi is off.

Snapdragon version here.
[Samsung Galaxy S7 Edge Real Life Review] cavags5:
New update for XSA

But standby is still good.

2% 7h with wifi on.
[Samsung Galaxy S7 Edge Real Life Review] avengethis1:
3% over 8 hours. On newest tmobile firmware and stock. Battery is much better to me than note 5
[Samsung Galaxy S7 Edge Real Life Review] THEGAMEPLAY94:
4% overnight 8hrs. Do you have anything disabled? I have iqservice and com.qualcomm.atfwd disabled on mine.
[Samsung Galaxy S7 Edge Real Life Review] avengethis1:
Nothing disabled but lookout virus crap that i can stand. No AOD. I had wifi, location and bluetooth on. The only thing i really have disabled is edge feeds.
[Samsung Galaxy S7 Edge Real Life Review] mettleh3d:
PG1 firmware?
[Samsung Galaxy S7 Edge Real Life Review] avengethis1:
Yes
[Samsung Galaxy S7 Edge Real Life Review] stone0504:
after the latest update ( Aug. patch and GPU driver update)

stand drain seen better.

4% for 7 hrs w/ AOD off, 4G data on, fb, ig, gmail, exchange mail, inst messengers.....

I think it's pretty good.
[Samsung Galaxy S7 Edge Real Life Review] kamrul.auntu:
How? Can you please let me know?
[Samsung Galaxy S7 Edge Real Life Review] cavags5:
That's impossible in stock,

The only way could be is in ultra power saving mode but i never try that with the s7-edge
[Samsung Galaxy S7 Edge Real Life Review] alvaro_castro:
turn off "S Voice app" ;)

---------- Post added at 09:11 PM ---------- Previous post was at 08:54 PM ----------

[Samsung Galaxy S7 Edge Real Life Review] hoaivu1508:
I think there are some services and packages still running in background when standby

Yesterday I found in Google Play an app can disable more than 100 bloatware (pre-installed packages)

So I try to disable some unused app like Gear VR services, SHealths, Splanner......It really save battery life

I also using "running packages filter" and "running services filter" function to quickly search

It named "BK Package Disabler Samsung" and work WITHOUT ROOT
[Samsung Galaxy S7 Edge Real Life Review] tamila:
Whatsapp is always on top of the apps that eat battery. screen comes second. do any of you have the same?

I am thinking this is the reason for less battery-life on my S7 edge. anyone can give any solution?
[Samsung Galaxy S7 Edge Real Life Review] cavags5:
Yes its true what'sup drsin a lot without using.
[Samsung Galaxy S7 Edge Real Life Review] javitolopez69:
Hi friends .solution for battery please ???
[Samsung Galaxy S7 Edge Real Life Review] whatwhatster:
It is getting really frustated now and I hope Nougat will fix the drain issue, no matter what I did and try until now nothing solves my problem.

Installed the firmware from september and again losing big time in standby, losing around 30% overnight. I am again back to the march firmware and this one is gold, such a shame this is a issue that is not getting solved.
[Samsung Galaxy S7 Edge Real Life Review] cavags5:
Thats impossible

Its something you did or didn't do.

Could be some app you have. Try to flash BTU BPHJ or XSA BPHC both are good , with XSA i loose 2 to 3% over night with wifi on.

There are lot of things you don't use you can disable.
[Samsung Galaxy S7 Edge Real Life Review] mumaster20:
You mean BPHJ with the CSC of BTU?
[Samsung Galaxy S7 Edge Real Life Review] cavags5:
Yes ,

I have BPHJ with CSC XSA .
[Samsung Galaxy S7 Edge Real Life Review] whatwhatster:
Nope everytime a clean install via Odin, flashing everything in the firmware zip and also my setup is the same. I also have EZ disabler.

My battery discharges very fast when using the phone and my S7 Edge is losing a whopping 30% in 8 to 10 hours with my screen turned off at night.

I tried every firmware until PDA G935FXXU1BPHJ & CSC G935FPHN1BPH3. So when downgrading back to PDA	G935FXXU1APBF & CSC G935FPHN1APBD my problem is solved. Overnight 2% to 5% and in general 1,5 day and sometimes even 2 days I can get with this firmware.
[Samsung Galaxy S7 Edge Real Life Review] cavags5:
And why you use EZ disabler, do you think that makes a difference.?

That is one of the cause that loose standby and don't improve nothing.

And i try it all ways.

There are other things to disable.

The best do far was XSA BPHC.

BPHJ is very close.

At least in my usage.

The one thing i have said in other posts is forget google now with Samsung cloud you don't need google backups or apps .

With me works.

With this rom in wifi is almost twice that in 4G.
[Samsung Galaxy S7 Edge Real Life Review] whatwhatster:
I standard have disabled around 90 apps, I have turned everything off from Google except Drive & Play. And Samsung is also turned off so those and backup etc is also off.

On all new firmware nothing helps, even when nothing is installed. Android system is high as hell and stays that way but with the march firmware there is no problem at all.
[Samsung Galaxy S7 Edge Real Life Review] cavags5:
When you say nothing installed is after you made a reset right.?

You have the wait for 2 charges until settle down.

Send you pm.
[Samsung Galaxy S7 Edge Real Life Review] mumaster20:
Would the CSC of a different country affect battery life? I currently use PHN as CSC, since i live in the netherlands and PHN is the standard.
[Samsung Galaxy S7 Edge Real Life Review] cavags5:
The standard is relative.

XSA like BTU is a clean CSC i Think PHN is too.

I think yes could make a difference.

I like XSA Australia and never use mine is TPH portugal.

With APC8 i reduced my Android System drain but my Android OS went crazy, so for me it was the same total drain almost.

I am not fond of running my smartphone without data,sync and location ( wifi/network ) on som maybe i just have to face facts and run it as is.... Wasn't able to find wich app i causing the Android OS drain, and i'm not very patince when it comes to stuff that i think just should work.

I mean, come on, how hard is it to release a firmware that actually keeps drain low wether you arw on wifi or on 4G?

Right now i'm on APB4NEE, the first firmware released in my country and people been getting like 48h standby with 4h SOT om this, but i'm just nor seeing it happen for me...

Guess i'll just have to carry my powerbank with me:(

Just take a brake my friend, Android OS is a *****, im not really sure how i do it but i did it. And im always on 4G from 8AM to 7PM and as you can see no more than this.

Im waiting to do last test.

One friend gonna borrow me other S7 edge and i gonna put same firmware same settings, same network provider like mine but other sim card. And use one 2 days and then change sim card.

I have a suspicious that really could be from provider.

Im waiting for other s7 edge to make other tests.
[Samsung Galaxy S7 Edge Real Life Review] ex0dusk3:
I have the latest 6.0.1 (G935VVRS4APH1) and have had MAJOR battery drain issues. At night alone while phone is off, it would drain around 10% - 15% by morning (if I leave it off charger)

I installed Doze last night and kept phone off charger and phone at 65% when putting it on the charger and by morning (8 hours) and it went down 5%. So that's definitely an improvement.

I also have GSAM Battery Monitor on and in "screen" it says:

Dishcharge While On/Off: 21% / 33% (off)

So that's a little worrying...

Never had this issue before the update. Battery would drain around 5-8 % without having Doze.

Apps taking up 62% battery drain:

Android System - 21.5%

Kernal (Android OS) - 12%

Waze - 5.5%

etc..

So it's something with Android alone... Hope they fix this..
[Samsung Galaxy S7 Edge Real Life Review] _Exeedy_:
In standby mode my battery drains normal but if the display is on it drains really fast every 1 minute 1 percent.
[Samsung Galaxy S7 Edge Real Life Review] lamboram:
mine sleeps like a baby as well..!

I have this phone since Nov.1, first few day I had drain between 5-15% during night (8hrs).

I have disabled bluetooth and wireless scanning, background sync and disabled bloatwares.

now my phone sleeps like a baby. I easily get 3-4 days between charge.

I am a very light user. (4 hours of normal talktime with LTE, a bit of whatsapp, 2-3 hours of SoT, almost 70+ hours of Standby time).

I am super happy about the phone's battery performance.

battery drain, I dont have any. 8 hours of sleep 0% DRAIN!!!!!!!!

cheers..
[Samsung Galaxy S7 Edge Real Life Review] scleone1987:
I have EXACTLY the same problem. Losing 6% per hour on stand-by at home with wi-fi. As I live in Italy I tried the Italian(branded and unbranded) versions of the firmware, from march to latest is always the same problem. Can I flash PDA G935FXXU1APBF & CSC G935FPHN1APBD (which I see from Sammobile being Netherlands - PHN) with Odin without problems?
[Samsung Galaxy S7 Edge Real Life Review] jejb:
I've had mine for 2 days now, left it unplugged at 100% last night. I installed all the latest updates that are available on Verizon. Lost 3% in 7 hours. Wifi and BT on, no backup syncs, no AOD. I'm very happy with that. I've seen that kind of performance with my Nexus 6P, but not for a long time now. Doze is working great on this one. I had a Note 7 for about 10 days before the 2nd recall, and it did not doze well at all.

Standby drain during the day seems excellent so far too.

Since I removed facebook app, my battery lasts 24h of heavy usage - 6h of web, 4h of hd ppsspp gaming,some other apps all the time connected to wifi.

A few days back facebook app drain 40-50% of battery over night in stand by, so yeah f@q facebook and all it's wonderful privacy
[Samsung Galaxy S7 Edge Real Life Review] Hashim97:
12 hrs Heavy usage (Games - Videos - Browsing)

airplane mode enabled (no sim card)

Wifi always connected

I get 9 - 10 hrs on screen heavy usage with a sim card, airplane mode disabled , location turned off, mobile data turned off and wifi always on

On light usage I have about 30% remaining by the end of the day (10 pm)

Note: I force stop the apps I dont use

Most apps I use: Twitter - YouTube - MxPlayer - Chrome - PPSSPP

I don't use Facebook

My usage

So here are a couple of screenshots since nobody believed me. (stock ROM)

Location ON with history enabled during the day, location off at night. Besides that nothing is disabled except the facebook app. (i use bluetooth only in the car for about 1h a day). WIFI is always ON and never sleeps, for me it seems that it drains less battery this way.

On one of the screenshots you will see that the phone is charging, I forgot to take the screenshot and I remembered when I plugged in the phone.

Power saving mode is activated automatically when the battery hits 15%

I have the G935V version, flashed to the unlocked firmware. My phone drains about 1%/hr at night in standby mode.

Google Play Services seems to be the culprit. It seemed to be sending quite a bit of data too (~200mb) so I turned off sync, but that didn't seem to help much. I think it reduced the data, but did not reduce the battery drain.

I've got Greenify and I hit "hibernate + lock screen" before going to sleep.

I've got a bluetooth garmin smartwatch, but that is always in the insignificant range in the battery drain list... unless its counted under the Google/Android system ones.

I have Wifi, Location, and Google Location History ON.

I've got Wifi and Bluetooth scanning OFF

Doze records show that it is Dozing

Anyone have any ideas on things to try? It sure would be nice to get close to those getting 0% drain in 8+ hours of sleep!
[Samsung Galaxy S7 Edge Real Life Review] traneupcqk:
I had a weird problem here.
