[Samsung Galaxy S7 Edge Questions and Answers] markm75:
I've tried all the suggestions here but cant come close to the OP results.. best maybe 5-6% drop per hour over 8 hours and 1hour screen time.. at work my metropcs (tmobile phone) signal is poor though.. 1-2 bars.. i have wifi on sleep when off, but often it really doesnt sleep.. turned off i might at best (rare) get 2% per hour, usually 10 min per hour wake ups.. then another 30 minute period i may hit 6% per hour off, and 22 mins wake up for some reason.. best i might see is imsservice using say 8 of 20 minutes waking the phone.. Its also not practical to disable key features/apps on the phone.. otherwise i might as well just have a flip phone :) But, in testing thats what i've been doing.. i thought maybe weatherbug was a major culprit and the tmobile app.. disabled both of these for instance.

edit:

I did a 30 min test in airplane mode with wifi ON (radio off).. basically 5 min held awake (10 per hour roughly) and 0% per hour drain while off.. i'm guessing its the phone radio causing the issue.. but i wonder if its poor metropcs or if its a "bad" radio, if thats possible. Unless certain apps that cause the drain just wont work or call home when only on wifi?

I still get kernel using 30% over 30 min with keep awake at 9min 16sec and a thousand possible processes.

In another airplane test i turned wifi off.. over 49 mins it was held awake 2 mins.. android system (50%) kept it awake 1min 30sec.. again caused by imsservice and Kernel was at 2min 5sec keep awake, overall 0%/hour with wifi off + airplane

And for another.. normal mode but wifi off.. over 45min 54 sec screen time, held awake 6min, and 1.3%/hr while off (no wifi use obviously and 45 mins of phone radio active), doze time light shows 34min with 76% screen off, while deep shows nothing

It's seems over night sleep like a baby, connections off and bad signal, and max 2% in 8h.

Great! Followed this and improved my battery
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
I said "by now most of you know there is a battery issue with the Snapdragon version"

By that statement I meant that if you browse this forum on a daily basis then you probably know a lot of us have or are experiencing battery issues.

After disabling reporting and wifi/bluetooth scanning the battery life has gone back to what I was getting before. I'm still running off of the same charge as yesterday after following these steps. Currently at 1 day and 3 hours with 36% left.
[Samsung Galaxy S7 Edge Questions and Answers] waternut13134:
How do I switch off wifi and Bluetooth scanning?
[Samsung Galaxy S7 Edge Questions and Answers] retsen:
It's under location, then improve location accuracy...but odd thing is that both wifi and bluetooth scanning are off for me by default.

Edit: I'm on the Verizon S7E...I followed all of the steps just a bit ago and will report back, as well, with my results. Odd thing is that, as mentioned, ram management is the same or less than when I had everything disabled through the Package Disabler...not saying that this is a direct correlation between battery and ram management but interesting that it the same or better. May be some validity to the point of view that while we can disable everything in package disabler, the system may still be pinging on those processes that we disables thus gaining us little to nothing.
[Samsung Galaxy S7 Edge Questions and Answers] gainstatom:
My WiFi and phone radio is always taking up 50%+. I only disabled AT&T and Amazon bloat.
[Samsung Galaxy S7 Edge Questions and Answers] belloni:
Anyone?
[Samsung Galaxy S7 Edge Questions and Answers] C0derbear:
As [MENTION=5297350]retsen[/MENTION] stated, under Location is one primary place.

You may also want to look at the setting "Nearby device scanning" under "Connections" -> "More connection settings" (on my SM-G935A anyway), as scanning for nearby devices can activate wifi. If you're rarely looking to connect to 'nearby' devices (as I can't, at work, so most of the time) then disabling this probably reduced power consumption.
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
Yea. I don't know what's going on. Did you follow the steps I listed. I had the same problem but now my held awake ranges anywhere between 0 minutes and 20 minutes during a complete discharge cycle.

Looks like you have a process in the background causing it.
[Samsung Galaxy S7 Edge Questions and Answers] belloni:
I havn't followed your steps yet, i'm on Exynos. However, i've been following you for the past week! (Not creepily). I had this issue on my last S7 before I exchanged it but I can't work out what app is causing it. I'm tempted to root to get to the bottom of it as it's quite annoying.
[Samsung Galaxy S7 Edge Questions and Answers] JazonX:
Thank you for the tips on Nearby scanning and usage reporting.

[MENTION=1957922]jrwingate6[/MENTION] I'm still having wifi over 50% on gsam even after enabling most of the apps and packages. Only AT&T things are disabled now, which shouldn't affect it.

When you're on WiFi does it seem like your battery is draining faster? The reason I ask is because sometimes GSAM also reports a large percentage for my WiFi and I don't notice the battery draining any faster than it would if I wasn't on WiFi.
[Samsung Galaxy S7 Edge Questions and Answers] gainstatom:
I honestly cannot tell. I feel like it does though, but it might just be my head lol. Also I'm only getting about 3 hours of SOT, which I think is really poor. I'm at 30 percent right now. Really desperate for a fix right now ?
[Samsung Galaxy S7 Edge Questions and Answers] EDubs11:
I have the same exact issue. I am on the T-Mobile variant (I should just say SD 820, because all the U.S. variants are the same) and my awake time is asinine. I followed your instructions. It just isn't working. I don't know. Something is preventing this thing into going into deep sleep shortly after the screen goes off. I know that sometimes it takes a few seconds for it to do that, but stay awake is almost 1/3 of the total time off of battery, which is not normal. I will be, also, following this to see what the F is up.

Also, the phone would not go into Doze mode unless I use Greenify to use aggressive Doze. Something is keeping the phone awake. What I would give for CPU Spy and Better Battery Stats....
[Samsung Galaxy S7 Edge Questions and Answers] Johno_Jan:
Hey guys to add to everything, I have the flat S7 T-mobile version. Ive tried the OP's suggestions except for the factory reset, yet.

I typically get between 14-18hrs of standby with ~5hrs of SoT.

My usage is moderate no gaming, just 1-2hrs a day of fb/youtube video watching, with good lte and wifi signal 90% of the time. BIGGEST gripe right now is that my phone is getting hot when im literally just browsing XDA forums on Stock sammy internet app. When it gets hot it starts to become choppy and keyboard even lags a bit.

Also gets hot when using snapchat or even stock camera to take photos...

Tommorow is my 14th day so should I return it and get a new s7 or is this normal? What are your temperatures like when browsing web.

(I Have a uniform display, so i dont wanna risk panel lottery)
[Samsung Galaxy S7 Edge Questions and Answers] Johno_Jan:
Check out my post above^

I have tmo too, hows the temperature on your phone man?

Btw, the Screenshot of the cpu temp was with internet app open and i had just receieved that call from my gf so it was hot before i was on the call.
[Samsung Galaxy S7 Edge Questions and Answers] Mekc:
13%, 12 hours since charge, 4 hours SoT. Do you think it's fine? The phone is warm even when I'm browsing. I see some people have 9 hours SoT and 1 day+ since charge...

Now got Package Disabler and killed almost all bloatware, will give it a try. Not really afraid - going to do a factory reset anyway...
[Samsung Galaxy S7 Edge Questions and Answers] nappent:
I believe many issues are from installed apps. For example my Tmobile s7 would randomly not go into deep sleep during the night when I had "cf.lumen" installed. As well I've noticed many non-root adblock would hold the phone awake like crazy. Even after Uninstaller the adblockers the battery still did not improve back to normal. Had to factory reset to fix it. I'm wondering if there is a issue with vpn and proxy connection even after the connection is disconnected... just stuff I notice.
[Samsung Galaxy S7 Edge Questions and Answers] belloni:
Ok so I changed my WiFi to sleep when charging and I enabled all apps again in package Disabler. Over 9 hours of charge last night and woke up to 97%. I disabled through application manager instead but look at GSAm, so annoying!!!

[Samsung Galaxy S7 Edge Questions and Answers] Mekc:
It's 4% in 9 hours of waiting. What's wrong? It means the phone can stand by for 2 whole days and lose just 20%.
[Samsung Galaxy S7 Edge Questions and Answers] belloni:
It's my held awake that is frustrating me :(
[Samsung Galaxy S7 Edge Questions and Answers] Mekc:
Can you please provide screenshots for these? And the one where you saw "restarting".
[Samsung Galaxy S7 Edge Questions and Answers] EDubs11:
I had a case from the beginning, but when I read this, I took the case off to see if it was bad. It gets a little hot, but nothing out of the normal. If you like the phone, just do a warranty exchange. They will do it easily. If you want to try the G5 or HTCs offering, go for it. I'm just afraid it is a 820 issue. Your phone I think, is just defective. Maybe the cooling pipe thingy, because it is definitely thermal throttling.

I love this phone, but this is making me crazy. The battery is still way better than my flat S6. I know I am just being greedy, but whatever
[Samsung Galaxy S7 Edge Questions and Answers] borisshnitkin:
I didn't take a screen shot of when it said restarting but here is a screen shot of where I found it
[Samsung Galaxy S7 Edge Questions and Answers] EDubs11:
Damn it. That isn't it on my device. Good find, though. I'm sure other people are having that problem.

I was so excited to have the Snapdragon for my AOSP fix. Samsung or -T-Mobile pulled a fast one (Fooled you! **in Dark Helmut voice**) The Exynos is an excellent chip, but Samsung's reluctance to release the source code for the chip set made me angry. Now, I am wishing I had snagged the international version.

EDIT: You disabled a Qualcomm package, so you clearly don't have the Exynos. Still a little early here.....
[Samsung Galaxy S7 Edge Questions and Answers] borisshnitkin:
I didn't take a screen shot of when it said restarting but here is a screen shot of where I found it. Mine said restarting near where the countdown is

It's a Verizon s7 edge. So snapdragon. You have to have developer options enabled to view the running services
[Samsung Galaxy S7 Edge Questions and Answers] EDubs11:
Yeah, I'm dumb. Clearly you have the SD if you disabled a Qualcomm service. Lol.

[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
I know someone just mentioned it but I too last night was going through the Developer Settings and noticed a few interesting things. I will post my findings later on today.
[Samsung Galaxy S7 Edge Questions and Answers] Johno_Jan:
Well, specifically during web browsing on wifi like maybe xda forums, not tapatalk, does your phone get to 94F??
[Samsung Galaxy S7 Edge Questions and Answers] gainstatom:
Going back to this, yes I do feel like my battery is draining faster when I'm on wifi. Right now I have nothing disabled at all and the result is this (down below). Any idea?
[Samsung Galaxy S7 Edge Questions and Answers] Mekc:
It seems that I fixed my issues with Package Disabler. I will see one more day and report here. I disabled a lot of packages at about 60% of battery life and rebooted. After that my phone stopped being warm all the time and battery drain ended. I guess I killed some process / package, that was draining my battery. Did not do a factory reset.
[Samsung Galaxy S7 Edge Questions and Answers] matthidinger:
My Exyonos phone is constantly semi-hot to the touch at 96F when the screen is on for more than 5 minutes, including tapatalk or browning the web. I've tried all the tricks in this thread and no help. The only thing different from most people's phone is that I have the FD model (dual sim). Is anyone else seeing this warmth? Is 96 normal in tapatalk?
[Samsung Galaxy S7 Edge Questions and Answers] gainstatom:
Update: something weird is happening today as every app I use for more than a minute seems to be super high on the app usage area. Anyone have the same thing?
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
How long were you watching You Tube for?
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
1% gone with 23 minutes off charger and 7 minutes on screen time seems okay to me.

By the way, I wanted to see if my battery was draining faster with WiFi on so today as soon as I woke up I turned WiFi on and haven't taken it off all day. It seems like my battery is actually draining slower even though GSAM is reporting a high drain from WiFi. What could possibly be happening is the percentage for phone radio is dropping while the percentage of WiFi is rising. Sounds normal too me.
[Samsung Galaxy S7 Edge Questions and Answers] Mekc:
All models are dual Sim. Use either Sim + SD or Sim+Sim.

At least in Europe.
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
Myself and a few others had this same problem. We all noticed it stopped after we stopped using package disabler to disable some packages. Nobody found out which disabled packages was causing it. Do you happen to have any packages disabled?
[Samsung Galaxy S7 Edge Questions and Answers] matthidinger:
I must have missed this comment, but I'm seeing the same thing (see a few posts up, my phone at 96F while using tapatalk). I am fresh off a clear-cache-factory-reset and did not use package disabler this time. It's quite warm under normal use today as well, so I'm just hoping it will calm down in a few days?
[Samsung Galaxy S7 Edge Questions and Answers] Travis Bickle:
European and American S7/S7 edge are not dual Sim. There is another version of S7 that is dual sim. The dual Sim version can do what you said Sim+SD or Sim+Sim .
[Samsung Galaxy S7 Edge Questions and Answers] Johno_Jan:
I uninstalled package disabler pro after reading about it causing battery drain in anothee thread. It wasnt helping at all. All ive done is disabled stuff through the application manager.

BT, NFC, gps, wifi ans bt scanning off, google app checking/scanning off, google diagnostics off, samsung diagnostics off.
[Samsung Galaxy S7 Edge Questions and Answers] gainstatom:
It gets worse. My WiFi right now is 63% lol. I'll report to you at the end of the day to give you the results.
[Samsung Galaxy S7 Edge Questions and Answers] C0derbear:
IF you have WiFi available to connect to, that would make sense to me.

For someone in my situation where the device could hunt-for, find networks, but nothing to connect to, enabling WiFi only chews more electrons. :^(
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
Have you turned WiFi scanning off?
[Samsung Galaxy S7 Edge Questions and Answers] C0derbear:
Scanning ... Network notification ... Auto connect to AT&T WiFi ... Nearby Device scanning ... all off.

Still uses more power WiFi on than off, at my work place.
[Samsung Galaxy S7 Edge Questions and Answers] Mekc:
When me and my wife were buying s7 and s7 edge in the official Samsung shop, they told me that there is no other version. But I checked Amazon.com and see now that there is. Strange.

How does single Sim version works? There's a slot for SD card, but you just can't replace it with 2nd Sim?
[Samsung Galaxy S7 Edge Questions and Answers] viking2.0:
Did a controlled test

Got a brand new phone and installed only 3 apps and disabled everything mentioned by OP and also some bloatware. Fully Charged the phone then took the 1st screen shot -in orange

Then did a clear cache factory reset and disabled everything and installed the 3 apps. Took 2nd screen shot and fully charging it and using it for the same amount.

I don't see much difference with factory reset. You might as well disable stuff mentioned in OP without factory reset
[Samsung Galaxy S7 Edge Questions and Answers] viking2.0:
After reset
[Samsung Galaxy S7 Edge Questions and Answers] Michaelmansour1997:
your only using 20% in 13 hrs?? how much SOT?
[Samsung Galaxy S7 Edge Questions and Answers] viking2.0:
Well there are only 3 apps installed and yes phone sleeps very well. 1% drain in 8hrs after disabling all the Google and Samsung diagnostic stuff.

On my other phone which has all apps installed I also see very little drain 2% in 8 hrs
[Samsung Galaxy S7 Edge Questions and Answers] Michaelmansour1997:
what 3 apps are they, i was thinking id slowly install my apps 1 by 1 too see if it is an individual app...do you use hangouts for sms, i seem to remember someone posting about hangouts battery drain.
[Samsung Galaxy S7 Edge Questions and Answers] viking2.0:
All the default installed apps + xda, twitter, play newstand. I also disabled Facebook, lookout, Android pay and Samsung and t-mobile apps from app manager
[Samsung Galaxy S7 Edge Questions and Answers] Michaelmansour1997:
ok, i have a verizon variant, i will try the same, thanks!
[Samsung Galaxy S7 Edge Questions and Answers] Travis Bickle:
He probably said that cause the dual Sim version is not officially available in Europe.

Here you can see the different Sim trays of normal S7 and dual Sim version. I don't know what will happen if you put the dual Sim tray in a normal S7, but I doubt it will work.

I agree that a factory reset most likely isn't nessesary but you never know what people have done with their phones such as loading settings and apps from a prior phone. I'm a firm believer in starting everything fresh.
[Samsung Galaxy S7 Edge Questions and Answers] Juuls:
They are identical, look close and see how the slot of the SD has 2 functions, SD and SIM (90 degrees rotated)
[Samsung Galaxy S7 Edge Questions and Answers] Romin69:
but the dual sim tray is different !
[Samsung Galaxy S7 Edge Questions and Answers] Juuls:
hmm, you are right, I see a little difference at the top of the 2nd Sim, weird though cause I saw some review about the single sim phones in which they showed a 2nd sim fitted in the SD slot.
[Samsung Galaxy S7 Edge Questions and Answers] Mekc:
I guess all the international factory unlocked phones are dual Sim then? If you are locked to an operator, you don't need a second Sim, cause you simply can't use it.
[Samsung Galaxy S7 Edge Questions and Answers] Juuls:
I found another diagnostic/reporting setting that sends stuff to Samsung!

Go to:

- Settings > Security > More Security (at the bottom) > Send security reports > toggle to OFF

[my android is Dutch so the words & order of words may vary]

There are more options there that you might find interesting turning on/off, I haven't touched them yet, just the above I disabled.

Next quest is 'Running Processes' in the developers settings. I already noticed the following:

- Word was running even though I never touched it, Disabled it.

- There was a proces (forgot name) that included 'Peoples Edge' & 'Feed view', these 2 also had permission to send notifications, I don't use both so I stopped them from running and disabled the main proces. (I disabled Feed view in App's when I got the phone but still the proces was running)

The quest continues...
[Samsung Galaxy S7 Edge Questions and Answers] Mekc:
Thanks. But for me it was already off, as I found out.

And a small update of my battery progress after doing some manipulations with package disabler: it seems I will get about 6-7 hours SoT this time with wifi on, gps on, bluetooth off. Before manipulations I was getting 3.5-4 and my phone was always warm.
[Samsung Galaxy S7 Edge Questions and Answers] viking2.0:
Looks like this is one of those settings which is turned off when you disable Samsung diagnostics during initial setup.

On my phone which had diagnostics disabled during setup had this setting turned off.
[Samsung Galaxy S7 Edge Questions and Answers] martinezma99:
I followed OP instructions and battery has much improved for me. I disabled all AT&T bloatware through Applications. No Package Disabler Pro.

Sync on, Location On (GPS, wifi, mobile networks), Bluetooth off, brightness on 50% Auto, no gaming, no Facebook, no theme, Always On Display Off, and Smart features off.

I use Google Now launcher with OK Google detection on, Google Plus, YouTube, XDA, Samsung browser (Adblock Plus) so no ads, Inbox, Voice calls (17 mins) and other misc apps.

Wifi On during Sleep (when charging).

Today I've been at home all day on WiFi and do get excellent AT&T LTE reception.

I've gotten incredible battery life but still see Android System and OS on position 1 and 3 for battery consumption.

This phone has incredible potential.

4 hrs and 14 mins of SOT at 50% battery life and off charger 13 hours and 37 mins.
[Samsung Galaxy S7 Edge Questions and Answers] Michaelmansour1997:
Still getting crap battery life, followed OP down to the tee, and even used greenify aggressive doze
[Samsung Galaxy S7 Edge Questions and Answers] ohmimpotence:
Has anyone tested which Location mode drains less battery? I'd imagine the mode that uses wifi and networks would be more efficient since it doesn't rely on GPS as much but I dunno.
[Samsung Galaxy S7 Edge Questions and Answers] C0derbear:
I think that depends upon your situation.

If you are always in an environment where the bluetooth or wifi can connect quickly to a network and thus exchange info, it probably helps.

In my case I only have access to wifi at home, so pretty much the rest of the time my phone will be wasting energy trying to connect wifi/bt, always falling back to gps.

My last android behaved this way (GS5), I can't see how the GS7E would behave any differently in this respect.

BUT, I don't know what the details are of how it works, location setting via wifi/bt, so <shrug>
[Samsung Galaxy S7 Edge Questions and Answers] ohmimpotence:
yea that's true, i'm thinking mostly of my situation where I'm at home most.
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
I don't know why your contacts process keeps restarting. I wonder if it's a sync issue.
