Android System plays an extremely large part of the phone. If you click on Android System while you're looking at battery levels, scroll down and you'll see everything it manages. This also plays a significant role when trying to determine battery drains, simply because this section covers so much of the phone's usage.
[Samsung Galaxy S7 Questions and Answers] insang-droid:
look at your data usage.. you can tell which app (if any) is constantly trying to use data. if it's not a necessary app, then disable background data on that app
[Samsung Galaxy S7 Questions and Answers] km8j:
Can others please add up their computed usage and see if it matches X% of total battery capacity? I mentioned in another thread mine definitely did not
[Samsung Galaxy S7 Questions and Answers] Linked Devices:
Not a bug, it's a number illusion.

It's actually a really good sign. It means that our S7s are so energy efficient that they use far less power then we're used to seeing. If everything else on our S7s used literally ZERO power it would report a ridiculous 100% battery use for Android System and that'd actually be great.
[Samsung Galaxy S7 Questions and Answers] km8j:
You are on the right track in general, but not in this case. 1) People are getting terrible battery life 2) Android System and OS are showing keep awake and CPU usage that shouldnt be there
[Samsung Galaxy S7 Questions and Answers] LuigiBull23:
True but not everyone is experiencing these battery issues.
[Samsung Galaxy S7 Questions and Answers] km8j:
Anyone seeing a difference with the new OTA?
[Samsung Galaxy S7 Questions and Answers] Linked Devices:
Okay that's strange I guess. I'm not having any issues with mine. My screen on time is usually about the same as my android system time which I found very surprising. I get almost 7 hours SOT with constant audio or video media playing while reading. I'm very satisfied as it is but if it does turs out to be a bug and I can get more I'll be stoked.
[Samsung Galaxy S7 Questions and Answers] km8j:
Are you referring to straight usage?
[Samsung Galaxy S7 Questions and Answers] LuigiBull23:
No issues on my end either. I've already exceeded 7hrs screen time over a 2 day period on battery.

It's 7 hours usage with the screen on, but I also constantly listen to audio and YouTube with the screen off too so if I never turned the display off while in use my screen on time would be higher.
[Samsung Galaxy S7 Questions and Answers] diosjeremy:
That's amazing. I disconnect my s7e at 8am.. and at 6pm I'm on about 15% with 5h of screen.

Have you done something? What tmo packages did you disable?

Thanks
[Samsung Galaxy S7 Questions and Answers] diosjeremy:
Thanks! What version do you have? Snapdragon or exynos? Root?

Just turned off BT this morning and Android system stopped being on top. I have SN820 version. Seems like BT was the cause for me. I left wifi and NFC on. No AOD, wifi off on screen off.

My battery is still crappy after the update. 90 minutes off a charger, 10 minutes on the phone, down 5%. Half the usage was Android system and os
[Samsung Galaxy S7 Questions and Answers] DirgeExtinction:
Update wasn't for battery life. It was the Google security update.

I originally wanted the Edge version due to the extra features and bigger battery. Does the Edge have the same issues? Does it at least last a bit longer than the vanilla S7?
[Samsung Galaxy S7 Questions and Answers] km8j:
Same issues but longer battery due to size

Do you have "Find my mobile" from Samsung active ?

I'm having the same issue and usage with the Exynos model. I read somewhere yesterday, that disabling the Bluetooth connection helps, but it is hard for me to test it, since I use it all the time.
[Samsung Galaxy S7 Questions and Answers] diosjeremy:
Followed your configuration and added a couple of services I find useful. I now got this with pretty hard usage:

Thanks!
[Samsung Galaxy S7 Questions and Answers] km8j:
Nuts.... I have almost everything disabled in that posters images, no diff.
[Samsung Galaxy S7 Questions and Answers] diosjeremy:
That's strange... I was getting around 12h of use and 5h30 of SOT before I applied his configuration.
[Samsung Galaxy S7 Questions and Answers] km8j:
Actually I believe that. The phone has great screen time. So if over 12 hours, you are doing constant use (i.e., watch 2 hours of video or web browsing), it sounds reasonable to get 5 hours.
[Samsung Galaxy S7 Questions and Answers] diosjeremy:
With the new conf I got more than 7h and did about 2h of video streaming(amazon video), 1 hour gaming (hearthstone), 4h spotify, almost constant tapatalk, twitter, fb and a lot of Web browsing.
[Samsung Galaxy S7 Questions and Answers] km8j:
I now realize in your signature you are on the Edge. Makes sense you would get more than a non-Edge.
[Samsung Galaxy S7 Questions and Answers] dclutter1:
I disabled most of the apps luigiBull23 posted, disabled BT, NFC, and Location and my battery has gone from

Yesterday: 12h off charger, 2h SOT, Bat = 20%

Today: 18h off charger, 2.5h SOT, Bat = 50%

Usage should have been very close to the same for both days. BT/Play Music in the car and gym, Reddit, Twitter, Clash Royale at work.

Soooo much better!

Edit: G930V
[Samsung Galaxy S7 Questions and Answers] TokyoGuy:
Just to give my two cents here. For reference my S7 Edge doesn't have battery drain from Google related system processes but does have major standby issues.

The first thing I do when getting a new phone is go into the Accounts setting option and uncheck every Google service I don't use. Roughly half of them, including Google Music, etc.

The next thing I do is go to Google Settings and uncheck the "Ok Google" support and all the options for the search fields (for example, search apps, search contact list...).

The more you have running in the background the more I've heard it taxes the battery. Especially with the Google Account options, I've heard it constantly pings to see if there have been changes made, and thus it's similar to having email ping every X minutes.

While I can't guarantee this will solve problems, at the very least people with this problem could try it out and see if it helps or not.
[Samsung Galaxy S7 Questions and Answers] km8j:
And now you have no cell phone basically... No navigation, no bluetooth, cant find your phone if lost...
[Samsung Galaxy S7 Questions and Answers] dclutter1:
Uhhh... Did you pay any attention to what's disabled? I have all of the features you mentioned. I mean, unless you use vznavigator for navigation.

Edit: well ok, no find if lost.
[Samsung Galaxy S7 Questions and Answers] km8j:
You said you disabled BT and Location... How can you use Google Maps?
[Samsung Galaxy S7 Questions and Answers] dclutter1:
By tapping the little button in the pull-down. That minor inconceivable before using maps is worth the extra battery savings imo.

Either way, now I'll re-enable each of those for a day and see if battery life goes back down. I'm hoping some of the bloatware I disabled was the culprit. I've always left bt and location on on my phones and it has never been much of a drain.
[Samsung Galaxy S7 Questions and Answers] theraptscallion:
I was having a similar problem, including the phone never dozing. I would routinely lose 20 percent a night. Here is what worked for me (820 variant).

Initially I disabled almost everything, but nothing allowed my phone to sleep. Finally, chasing ghosts, I checked the settings on my router. Strangely, when I changed from compatability mode to N-only, my battery usage stopped. Last night, 4 percent instead of 20. I then re-enabled all the packages and doze still worked.

I suspect it's a very specific Qualcomm wifi driver bug.

That all being said, android system is still using 25 percent of my battery, but I've gone from 8 hours to 28 of battery life, so I'm not bothered.
[Samsung Galaxy S7 Questions and Answers] DarkWolffe:
What other modes does your router support? Is it B/G/N 2.4GHz only, or does it also have A/N(/AC) as well?
[Samsung Galaxy S7 Questions and Answers] PunishedSnake:
I'm using the ac portion no issues
[Samsung Galaxy S7 Questions and Answers] xxaarraa:
Very interesting. I just checked my comcast router and I only have "b/g/n" or "g/n" modes, no way to select n only. It is currently in "g/n" and I have battery drain. I have another router I can try, but curious if anyone else can confirm that switching to "n only" mode solves this issue.
[Samsung Galaxy S7 Questions and Answers] supernova_00:
Don't forget that if you turn on GPS that wifi scanning automatically turns on and doesn't turn off when you disable GPS again.
[Samsung Galaxy S7 Questions and Answers] theraptscallion:
My router isn't AC compatible (maybe someday, if Comcast gets their speeds up enough to matter). I had the 2.4 set to B/G/N and changed it to N-only.
[Samsung Galaxy S7 Questions and Answers] mmorabe:
I tried different profiles with Package Disabler the last few days, which by the way, the fact we even HAVE to do something like this to our phones to maximize our battery life is asinine. Over the weekend, I tested a slightly adjusted version of the package posted a few pages ago, and my phone decided it would finally Doze (TMO GS7). By the end of the day (I forgot to take pics) I easily had 5+ hours of screen time, tons of surfing the web/reddit etc., videos and whatnot. I WAS at home however and I have perfect bars (didn't need Wifi at home).

What I AM noticing today at work, is that since reception to TMO is ****ty as is, the phone is struggling a bit again. This is always going to be the main reason the phone battery dies as the radio is consistently trying to find a stronger signal. So far though, I'm very happy with disabling a lot of these packages and will keep updating as I progress through the week and see if the Radio signal is really effecting the battery drain.
[Samsung Galaxy S7 Questions and Answers] km8j:
What did you disable that actually made the biggest difference? Your phone not getting a signal wont show in android system
[Samsung Galaxy S7 Questions and Answers] amartins02:
To add onto the previous comments regarding WiFi...when I am at work on the guest network I notice that I also get a reconnected message for the network. It seems as if the connection is always dropped and then reconnected over and over. I am wondering if this is keeping the phone awake and preventing it from dozing.
[Samsung Galaxy S7 Questions and Answers] rogerchew:
agreed, this is asinine...i'm finishing the day with Android OS and System taking up 50% of my battery and I have about 4 hours SOT. The thought of them not taking up 50% and performing more like my Nexus 5x just in terms of battery usage makes me cringe at how much more battery life I could get out of this phone. Hopefully a fix finds its way to our phones soon.
[Samsung Galaxy S7 Questions and Answers] mmorabe:
I don't know exactly what helped, but i DID notice today (at work with ****ty radio signal but good Wifi) that my battery drain is still higher than when I was home yesterday with good radio signal. I honestly would recommend to import Luigi's? disabler xml, and then uncheck the programs you DO want to use.

Note: Using his XML, the only thing that doesn't work really is Google Now (search bar and the "OK Google" thing).
[Samsung Galaxy S7 Questions and Answers] xxaarraa:
Android system is still the # 1 user, followed by screen, followed by Android OS, then cell standby. However, after most recently enabling "smart network switch" I may be experiencing slightly better standby. Phone came off charger yesterday morning at 6 AM (24 hours ago), I am now at 51%. SOT isn't that high, only 1:35 so far. Here are my settings and stats:

Screen brightness manually set to 75%. I like the brightness all the time, makes the beautiful screen pop.

Location mode set to high accuracy. I like all the location features of Google now and I am a frequent waze user and waze likes high accuracy mode.

VOLTE set to on. I like how quickly phone calls connect with VOLTE on.

Wifi calling set to on, however I leave Wifi disabled from about 8 AM to 6 PM while I am at work.

BT set to on. I always leave BT on so it can connect to my car.

AOD set to on. I love this feature.

Download booster set to on. I got tons of rollover data, so might as well.

--

Package disabler pro debloated. I'd say moderately aggressive, but left Samsung pay and Gear VR packages intact.

Wifi scanning disabled (I do realize wifi scanning is still being used when location is requested by apps due to high accuracy mode)

NFC disabled

Scan for nearby devices disabled

"Optimize battery usage" turned on for all but a handful of apps including system apps

Turned off "google location history, voice & audio activity, youtube search history and youtube watch history" in google account settings

Restricted background data usage for all but handful of applications

Notifications disabled for all but handful of applications

Wifi smart network switch enabled

Based on 2 weeks of usage, despite the android system drain 'issue', I am getting the same battery life as my S6E, WITH a bunch of features enabled that I had neutered on the S6 (on the S6E, I had no VOLTE, no wifi calling, no 75% screen brightness, no AOD). At the end of a normal work day, I have 65-70% battery left, and for all the features I now have enabled, I'll take that deal everyday. Nothing to complain about here, though I will keep tabs on android system battery drain issue. As someone said, I think it's more of a bug in battery stats reporting than actual battery drain.
[Samsung Galaxy S7 Questions and Answers] mmorabe:
This is great news so far. I DID notice yesterday (I'm so bad at remembering to take SS's), that it was A LOT worse still like I reported before. Today, I'm at work again (lost 3% driving in on a 20+ minute drive), but that was with Location/BT turned on.

I'm now Wireless On (for wifi calling and SMS), no Location/Bluetooth for now), disabled Google Now (Google Search Bar in PDP), and my phone stablized in stand by at 93% longer than it was.

I'm going to be turning things on 1 by 1 to see who the real culprit is (I'm thinking it might be BT or Google Now) and see if I can pinpoint what is causing the phone to drain a ton.
[Samsung Galaxy S7 Questions and Answers] mmorabe:
Also kept Location/GPS off this morning off the charger and battery is holding MUCH better with Google Now disabled. Tomorrow, I will keep Google Now on, but keep Location off ONLY if I need it.
[Samsung Galaxy S7 Questions and Answers] rogerchew:
Seen multiple screenshots from exynos users and sd820 users. There's a very big difference in terms of what process is using battery. All SD820 screenshots have shown Android System and Android OS battery consumption as the top 3 drainers with a combined usage of anywhere between ~40-50%. When a Exynos user posts their usage, their Android System and Android OS are always sub 10% each combining for a total of roughly ~15-20% total usage. What gives?!? is there a bug on the SD820?
[Samsung Galaxy S7 Questions and Answers] km8j:
Im went and "rebloated" per the suggestions around here and nothing magical happened. 4 hours off the charger, 17m SOT and an abysmal 89%.
[Samsung Galaxy S7 Questions and Answers] mmorabe:
I think a lot of it too could obviously be how we all use the phone differently. I know by debloating + someone's Disabler Pro XML and keeping GPS off only when I need it, my battery has greatly improved over when I first received mine and added all my apps.

I'm going to keep watch over the weekend as well and see if the battery holds true in better cell reception as my office has crap and having to use Wifi for everything here (while the radio is constantly trying to find good signal) is killing my battery off a lot more than if I were at home.
[Samsung Galaxy S7 Questions and Answers] km8j:
There are way too drastic of differences for it to be usage based
[Samsung Galaxy S7 Questions and Answers] mmorabe:
You're right.

I just looked at a coworkers LG g4 and the android system and os are waaaaaaay below the screen usage (and rhapsody for his usage today). I am still irked why both of them are screwing it all up.
[Samsung Galaxy S7 Questions and Answers] Nextstep:
On my Galaxy S6 the battery drain was S Health and Google Drive.

Disabled those and drain stopped. Not so with Galaxy S7
[Samsung Galaxy S7 Questions and Answers] mmorabe:
I'm hoping we can figure out how to reduce this Android battery usage soon.
[Samsung Galaxy S7 Questions and Answers] Inty4:
Yeah, if I don't fix this soon, I will return the phone, I hope the warranty works in the case of "I only have mediocre battery life, and I want it to be great."
[Samsung Galaxy S7 Questions and Answers] PunishedSnake:
I'm going to switch to the HTC 10 if we can't get it resolved
[Samsung Galaxy S7 Questions and Answers] mmorabe:
Good news. I'm using Greenify's Extreme Doze feature and getting very good battery combined with my Disabler Profile and shutting off stuff I dont need.

Checking GSAM, the dozing is now working in minutes rather than hours.

Also I was using the phone rather heavy as well this morning during Easter brunch.
[Samsung Galaxy S7 Questions and Answers] sprog123:
The conspiracy theorist in me thinks Samsung is intentionally gimping the software on the SD820 versions to make their Exynos ones look better. They can't explicitly trash Qualcomm this year like they did with the SD810 overheating rumors (knowing engineers that actually worked on it, it's amazing how FUD spreads like wildfire on the internet, and Samsung's marketing machine knows how to work it very well) since Qualcomm signed a huge fab deal with them to make the SD820.

This also would explain why Samsung decided to lock the bootloader on all US SD820 versions. If they had left it unlocked on the T-Mobile version, for instance, it's clear people would have flashed optimizations for SD820 from other ROMs and noticed the improvements and then it would have made Samsung's software optimization look bad. This way, they get the best of both worlds. Implicitly putting down the SD820 version making people want to get the Exynos one instead, meanwhile instilling an even worse impression of Snapdragon in the public. Pretty sneaky of them.

Time will tell when the other SD820 flagships are released. The HTC 10 is rumored to be putting up an Antutu score north of 150K now well above the S7. The Mi5 scores are also pretty impressive. I bet they won't have any AndroidOS process bugs either that drain the battery.

If you look at the mAh burned by AndroidOS on SD820 version of S7 compared to the mAh for screen on time, it's clear SD820 version could get almost double screen on time matching the reports of Exynos versions with very little AndroidOS burn.

Guys, it's clearly a software issue, and Samsung is playing games and favoring their in-house platform. I'm contemplating returning my S7 and getting the LG G5 or HTC 10 instead. Too bad the Mi5 isn't available where I am. You know those OEMs will have a vested interest in extracting the maximum performance out of the SD820.
[Samsung Galaxy S7 Questions and Answers] sinman02:
I've been getting pretty average to below average battery life on my AT&T S7 edge. I've been keeping an eye on this forum.

Then at around 930 pm tonight, I decided to use the debloater app and disabled a bunch of magenta colored "boatware".

Notice the difference?
[Samsung Galaxy S7 Questions and Answers] laureanop:
Your theory is definitely valid, but I doubt a company like Samsung would have such poor business ethics.

Let's stay tuned for the LG G5 forums for when they start complaining about excessive battery drain from Android System. I believe there's something inherently wrong with the SD 820 and now it seems that the Exynos is having overheating issues when pressed as well.
[Samsung Galaxy S7 Questions and Answers] Inty4:
But the thing is, that many of us in this thread have the Exynos version, and are experiencing these battery issues as well. I think it's software related. If anyone figures out exactly which sevices to disable, I'd be a happy camper.
[Samsung Galaxy S7 Questions and Answers] mmorabe:
I haven't done heavy SOT testing, but with the Disabler XML that was posted earlier in the thread a bit ago, and bringing back a couple things AND the addition to Greenify's Aggressive Doze feature, I'm getting very good daily usage (I think I've easily been 3-4 hours with a LOT of battery left).

If you'd like me to test maybe playing a video for X amount of time and seeing where the battery falls, I can do that as well. My setup is currently ideal for saving battery when the device is locked.

What's on:

Autosync

Bluetooth

Location (only when using Navigation)

50% Screen brightness

Disabler Pro

Greenify

I can update my results tonight before I go to bed.

Shouldn't we all tweet or message Samsung about this so we get more attention to it? I feel like if a lot of people compalin about it they might do something about it.
