I literally bought this phone 20 hours ago :D and during my first battery cycle yes. but despite the android system drain it lasted really long! compared to my note 4 with damaged battery.
[Samsung Galaxy S7 Edge Questions and Answers] Vogal:
My findings: decent battery life if I make a clean install. After a firmware upgrade, android system wakes up and I get poorly battery life.

But is so annoying make clean install after each firmware update...

Could be a Samsung problem? In my old s HTC I didn't had this issues.

My Galaxy S7 after updating via air from 6.0.1 to official Android 7.0 is discharged by sole "Android OS" in 24 hours (no other processes except cell idle).

Nothing did not help: wipings; factory resets; cache cleanings; deinstalling of all user apps; downgrade to 6.0.1 and upgrade again to the clean 7.0; lowering all display/phone/apps settings; turning off all sensor and radio consumers except cell...

Totally frustrated. Have to downgrade to 6.0.1 until fix.

See how many users reported similar issue here: code.google.com/p/android/issues/detail?id=211226

[Samsung Galaxy S7 Edge Questions and Answers] SHREYSTARK:
It is actually after the Nougat update that i myself have encountered a lot of excess battery drain so it went all the way from 6 hours of screen on time to 4 hours of screen on time (ideal non changing conditions as per my personal daily monotonous usage before and after the update comparision)

You Screen On times and System battery drain may be different based on your settings and usage patterns but important is that it has decreased little more that what may be called as ignorable

Otherwise overall the phone is excellent in battery life and performance from the day i recieved it

Same here mate, same here.

The thing that bothers me is that Google has either ignored this or failed to fix it.

Read quite a lot about Nexus user lifting this issue during both Beta tests and official releases and have yet failed to get this fixed, think the Nexus is on 7.1.1 by now.

Hoping we'll see a fix but really don't think so.

Same happened to me after update to Nougat. On 6.0.1 I've got at least 36h with mediocre use Always On feature, on Android 7.0 battery drains in 18-20h and the phone is noticeably slower.

Hoping we'll get the update soon.
[Samsung Galaxy S7 Edge Questions and Answers] MillerTyme:
My battery life has been terrible for a few months now, like 2 to 3 hours SOT tops with huge Android OS and Android system drain even when idle. Tried reading as much of this thread as possible and I want to try flashing an older firmware to see if that helps. My question is I am on g935vvru4api3 and I read somewhere because of the bootloader I can't downgrade? Is that true and if so what are my other options?

Thanks
[Samsung Galaxy S7 Edge Questions and Answers] Galactus:
Still don't understand what happened with newer updates. There is no way I can get this battery life on 4G in Nougat. 3 Hours SOT with 50% remaining and 18+ hours up time? On Nougat.............NOPE

After couple months with Nougat, and flash some Nougat roms, and always 4G drain, now I decide to go back to MM and drain stop, no OS,

And now what is the explanation?

Same apps same settings as always.
[Samsung Galaxy S7 Edge Questions and Answers] Galactus:
My battery life on Nougat has gone up, after I disabled VoLTE.

In 4g I could do 1 hour SOT per 10% of constant use but of course background drain limits.

First charge with VoLTE disabled, 6 hours SOT, 25 hours standby, no apps disabled. Could probably hit 8 hours SOT in a average days use (17 hours)
[Samsung Galaxy S7 Edge Questions and Answers] cavags5:
My battery maybe it's a little faulty already.

Its impossible to do 1h 10%

Even with low brightness,

Maybe in wifi, not 4G,

I already try it without my email app, but I have always sync off, but no improvements.

Nougat drain a lot.

I know I use a lot full brightness during the day, but with MM that's not a problem.
[Samsung Galaxy S7 Edge Questions and Answers] Galactus:
Battery for me now is excellent.

38 hours standby

Nearly 5 hours SOT

4g, no WiFi

Bluetooth enabled

Location on battery saving

NFC on

Sync on

I can do 1 hours SOT per 10% if I use it non stop
[Samsung Galaxy S7 Edge Questions and Answers] cavags5:
I can't do 1h 10 % in 4G, it's impossible and only 4G and Bluetooth on, only in marshmallow, I use during the day 4G but almost all the time full brightness, because im on auto, but at home I use wifi, and even with wifi I can't do 1h 10 % only non stop like you said, I gonna test s8 when arrive, if battery is worse with my usage, I will choose mate 9.

Conection to wifi, 4G signal, and other apps work much, much better with Mate 9.

Only after we use, then we can see the difference.

I'm amazed that after 256 pages of comments no solution has yet been found to address this problem for everyone. I'm pretty sure I've tried every combination of tweaks mentioned in this thread over the past year and am still having no success. Makes me think that this may be a hardware problem or some setting that is hardwired into the s7. If it's not a hardware problem, I can't understand why Samsung would not make addressing this issue more of a priority. It is pretty much the only issue that I have had with this phone, but it is a fundamentally important one.
[Samsung Galaxy S7 Edge Questions and Answers] tuk1maar:
It's simple. Get an Galaxy A5 2016/2017 if you want batterylife. My mother has that phone and she's getting about 7-8H (~1800mAh) of SOT on 100% brightness over ~4 days. Android System used on her phone ONLY 44mAh after 4 whole days! I upgraded from S7 Edge to the S8 and the S8 also has the Android System drain. Truly pathetic if you ask me...I have no clue on how to fix it.

By the way, idle drain on my S7 Edge became close to 0% per 24 hours after I removed my sim card and SD card and put the phone in flight mode. So....perhaps it's related to the simcard and SD card?
[Samsung Galaxy S7 Edge Questions and Answers] nobody291:
I'd been having the "Android System using 30% of battery and always being warm" problem for a few weeks with my GS7 running Nougat. I've slowly been working my way through the suggestions in this and other forums. It may be different for other people, but what finally resolved the problem for me was going to settings->connections->wi-fi->advanced->keep wi-fi on during sleep, and changing the setting to "while charging". Now, my phone is cool most of the time, and Android system is responsible for 8% of battery consumption instead of 30%. I think this suggestion appears earlier in this thread, but it took me awhile to find.
[Samsung Galaxy S7 Edge Questions and Answers] mashardpro:
Only 4% on my phone. I'm not on stock rom
[Samsung Galaxy S7 Edge Questions and Answers] L4s7Re4lG4mer:
Ok Guys I have fix for your battery drain and it is pretty simple. The drain is caused by Google apps and keeps the phone awake but not only that it also tries to receive GPS data all the time that is total battery burner. SO fix is simple just go to setting GPS and set it to DEVICE ONLY. Not High Accuracy nor battery saver. This is only thing you need to do and your phone will be normal and have great battery life. Comment after you if try this .

[Samsung Galaxy S7 Edge Questions and Answers] bluemu:
Thank your for this suggestion L4s7Re4lG4mer. I had changed this setting a long time ago, but was still having trouble with my phone waking constantly when my screen was turned off, so I thought that this setting must not have made a difference. However, when I went to check the setting, I noticed that it was set to "high accuracy" , so I set it back to "device only" . I immediately noticed a leveling off of my battery drain when I turned my screen off. Then a day later I noticed that my battery started to drain again when my screen was off, so I thought the benefit I noticed must have been a fluke. Just to be sure, I re-checked the setting and it was set back to "high accuracy", so I realized that I must be doing something that was changing this setting wihout knowing this was the case. I shortly realized that some apps notice when this setting has been changed and try to get the user to agree to change the setting back, but they use somewhat different wording to describe the setting, so I was not picking up on what I was actually being asked to change. Since realizing this and not accepting this change, my battery drain while my screen is turned off has improved immensely, although the battery drain when my screen is turned on still seems too high. Nonetheless, this is a major improvement, which I very much appreciate. The one thing I'm not sure about is if I did have this setting set to "device only" before switching from Marshmallow to Nougat (I definitely thought this was the case) , and if the "device only" fix works for Nougat, but not Marshmallow. Doesn't really matter that much now that everyone is on Nougat. Hoping that the observed benefits of this fix stick over the coming weeks!

[Samsung Galaxy S7 Edge Questions and Answers] Deathmeter:
Sorta unrelated but still on the topic of battery life, AccuBattery says my phone battery has a wear level of like 74%. So that's a quarter of my phone's initial capacity gone in less than a year. I heard Samsung replaces batteries if the capacity drops below 80%. Anyone know anything about this?
[Samsung Galaxy S7 Edge Questions and Answers] SEVENEDGE:
Guys, upgrade!! Samsung is giving 200 for ANY WORKING android or smartphone, as long as it works and in good cosmetic condition (or nothing more than usual wear and tear). So less than 500 for the S8 and less than 600 for S8 PLUS. But a good condition android or iphone for less than a 100, and sell your S7 Edge for about 350 or so, if you can get that. So and S8 plus would be like 530, minus 350, you get an S8 plus for 180 or so before taxes!! The S7 Edge, sadly, will be obselete because of battery life, unless you probably have an exynos processor. The SD820 doesn’t help the S7 edge, and when you get the S8/S8 plus, you'll notice the efficiency of having an SD835.

Have deleted most of the apps that i installed but still android system and OS is going higher and higher :(
[Samsung Galaxy S7 Edge Questions and Answers] DeeZee3000:
Wow, so, I'm having the same problem discussed here, and it's driving me insane, knowing that my battery could literally last twice as long without this nonsense going on in the background.

But it gets worse than that.

I am using NetGuard as my firewall, and the "Android System" collection of 82 apps/services is blocked in it.

But I would like to share the access attempts log. Because it makes no sense whatsoever.

"Android System" is constantly trying to contact a bunch of social networking sites, most of which I've never used even once in my life.

But then I caught it contacting a private WordPress blog, containing nothing, but a bunch of encrypted text, or possibly instructions (code) for download?

Just take a look at tigerukblog.wordpress.com

So not only is my SGS7E wasting half of it's battery on this, it could be infected and running some sort of spyware?

Among other things the "System" was trying to contact, were some obscure addresses registered to people in Asia.

Am I paranoid, or is this weird, someone please tell me...

I'm attaching my blocked access attempts log, and I considered the possibility, that my Android System is using so much battery because it fails to connect due to my firewall, and keeps trying, but I'm guessing many of you don't even have a firewall, and some of you have an even higher drain than me....

EDIT: Oh, I saw some people suggesting an upgrade to Galaxy S8.

I went into some stores and looked at their display models, and checked out the battery drain. It's the same thing!

My brother has an S6 on the other hand, and his Android System contains practically the same "Android System" apps/services, but his battery drain for these is just a couple of percent. As it should be!

[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
The latest Tmobile update fixed my high battery drain in standby and when using mobile data however my wifi is still broke. If I download apps in the store over wifi then my phone gets very hot on the right side and I can see my battery percentage drop roughly 1% every minute. If I download the same apps over mobile data then the phone only gets ever so slightly warm on the right side and my battery drops 1% every 5-8 minutes. Again this is while downloading and installing applications.
[Samsung Galaxy S7 Edge Questions and Answers] Carterman32:
I called Samsung. They told me they're just the manufacturer and have nothing to do with making the OS. If there's a problem, Android has to deal w it. The people on both their chat and voice lines are from foreign countries and have no real information. They don't even report the problems. They just shell out stock advice. This issue will not get fixed until Google gets involved. Probably at least 4-6 months.
[Samsung Galaxy S7 Edge Questions and Answers] laureanop:
That's such a bunch of bull****!! The updates come from Samsung and the carrier, not Android. Android only provides the aosp base and we all know how heavily Samsung modifies and codes on top of it!!

Shame on them for thinking we're stupid!!
[Samsung Galaxy S7 Edge Questions and Answers] Carterman32:
I waited for almost three hours, twice, to talk to an American representative. I even asked to talk to an advanced level if tech support. Both times, the Samsung rep said there's nobody to transfer me to, because they only manufacturer the phone and put some of the apps on. They have nothing to do w the OS.

Verizon said they had no record of the issue. They said that the fixes aren't generated by them, anyway.

If you want a fix, you need to find a way to alert Google. Then they need to care and find a fix. I guarantee it'll be months, if ever, that this is repaired. If you are worried about the battery, either return the phone or buy one of those battery based cases. This is not going to be a quick fix since it's probably an issue embedded in the kernel. Unless someone can achieve root, this version of the phone is going to be flawed.
[Samsung Galaxy S7 Edge Questions and Answers] km8j:
This isn't a Google thing. It's a Samsung thing. People just need to go to media Dept or social media. It's only the SD model as everyone has mentioned and if doesn't effect other Android devices. Some people started posting to Twitter it seems. Everyone needs to. The thing is people at Twitter are going to try and troubleshoot like we are all idiots
