After updating to the latest PC8 build, the Android System drain is gone and battery life is now quite amazing and as good or even better than I'm seeing the Exynos guys posting. Sorry no screenshots, but here are my stats:

Battery remaining: 7%

Time on battery: Almost exactly 3 days

SOT: 4hr 42min

Top users:

Screen 20%, 642mAh

Cell standby 18%, 592mAh

Maps 13%, 434mAh (over 1hr GPS navigation usage)

Device idle 11%, 371mAh

Android system 10%, 346mAh (this used to be almost 1000mAh before the update!)

Android OS 7%, 252mAh

Usage hasn't been that heavy (hence the large portion of idle time), but mostly limited to GPS navigation and a few hours of web browsing. Given that I've burned about 1500mAh for 3 days for idle/standby/Android drain, that roughly translates to an average idle current of 21mA. With 7% remaining, which is about 210mAh (7% of 3000mAh battery, though Android OS 7% draw shows as 252mAh), I could expect another 10hrs of standby time, so nearly 3.5 days standby with almost 5hrs SOT. Amazing. Alternatively, my SOT draw is around 140mA, and I estimate very roughly say another 140mA for system, meaning another 0.75hrs of non-intensive usage SOT! 3 days of standby with 5.5hrs SOT. At those levels of drain, I'm estimating somewhere in the 9hr range of very heavy continuous use SOT! This is also my first charge cycle since taking the update. Pretty impressed.

Has anyone with AT&T received this update? If so what version number is it?

I am using the Exynos 8990 S7 & I was getting very good battery life on the initial factory build but from the time I have updated my phone to the new April security update, the Android System usage has gone up like crazy. I really thought the update was to fix the issues but seems like it's going bonkers on my phone?

Anyone else facing such issues?

I recently went into recovery mode & wiped cahce, let's see if that helps.
[Samsung Galaxy S7 Questions and Answers] mmorabe:
Are you still getting this good of battery life? Android os decoded to run havoc again recently.

Good battery life here, and I still don't have the update (Verizon).

Ok, looks like I judged too quickly. Android system and OS just keep sucking away! Started with the April update on the Exynos version (Canada). Sitting at 81% battery, 5h30m, android system plus OS = 165mAh, screen 142mAh with 1h23m SOT. Nice Samsung...
[Samsung Galaxy S7 Questions and Answers] arfaoui:
I have doxngraded it to the previous firmware and now it is OK no batterie drain
[Samsung Galaxy S7 Questions and Answers] greyhulk:
This just means you use your phone more. Try leaving it laying around without touching it for a day and see what your highest battery drain is reported as. The Android OS drain is real and it's #1 on the list for people who don't use their phones nonstop.

The Exynos model doesn't have this issue.
[Samsung Galaxy S7 Questions and Answers] turtuv:
After last update even the Exynos model has this issue.

Yup, Exynos right here. Have the issue since the update on April 18.
[Samsung Galaxy S7 Questions and Answers] seanie2322:
Yep exynos model here too. Lost 12% battery over night with no WiFi or cellular data , location, AOD etc . The culprit according to GSM was the Android system. When I first got the phone I used only lose 1-2% overnight. A shame as the phone as a whole is fantastic

haven't read the thread but just wanted to add my issues. i charged the phone before going to sleep (9m screen on time just minor browsing) and woke up this morning to 77% battery. What can cause this kind of drain with the phone not being used? And of course there are a plethora of apps tied to Android OS so it's near impossible to figure out which one(s) is/are the culprit.
[Samsung Galaxy S7 Questions and Answers] seanie2322:
Seems your WiFi and data were on the whole night? Perhaps that was the drain. Although 23% drain overnight is quite a lot. I'm only experiencing 10-12%
[Samsung Galaxy S7 Questions and Answers] GbizzleMcGrizzle:
Do I've had insane battery drain on my flat. Changed it up and two hours later with the screen off I've got 77% battery. I've been doing everything to try and fix the battery and the only thing I ever haves in is mobile data because it's the only data I have. Well browsing through this thread I noticed someone mentioned to turn off nearby device scanning. I just used the search feature because I've never seen it. Well I turned it off and note I had 1% battery drain all night. I'll post my before and after screen shots later but. If you are having a problem look at that nearby device scanning, it made a world of difference and allows me to keep using a functioning $800 phone instead if a heavily disabled phone that is comparable to a $100 MetroPCS phone.

I had no WiFi on all night.
[Samsung Galaxy S7 Questions and Answers] fredriks:
What happens when you do the same but on WiFi instead?
[Samsung Galaxy S7 Questions and Answers] seanie2322:
Still around 12% drain with WiFi on i thought my router packets might have been waking the phone at night which is why I turned it off to see if it would make a difference.

Do you have viber installed?
[Samsung Galaxy S7 Questions and Answers] fabiok81:
If you will try to install cpuspy, you will see that your phone can't going to deepsleep...

When I updated my s7 (exynos) I had the same problems but I know that wifi and data weren't the real problems. It's something in the firmware and in fact, when I downgraded, these problems went away.

If you use package disabler, uninstal it...perhaps you have disabled some package that make your phone awake

[Samsung Galaxy S7 Questions and Answers] seanie2322:
I did disable a lot of packages in the last few weeks with that app so perhaps I caused the drain myself. I will uninstall it and see if this makes any difference thank you!!

---------- Post added at 12:40 PM ---------- Previous post was at 12:39 PM ----------

[Samsung Galaxy S7 Questions and Answers] fabiok81:
No but set viber without anonymous analytic data... I have viber too and there are no awake problems

So I'm ticking the box for viber will use Wi-Fi 's sleep policy as opposed to always connected? Thank you I hope these tips help

Yes, if you downgrade with Odin you don't make trip your Knox and your warranty is valid too.

I downgraded to my factory Sistem because the last Fw made my phone awake.

You can find all your firmware in sammobile

[Samsung Galaxy S7 Questions and Answers] kern417:
yes, i never turn either off. i didn't on my gs3 and had great battery life (granted it was rooted). i would like to use the given features and still get the battery life i had originally, which sounds like a lot of it is due to the latest updates. i finally sucked it up and turned off the always on display, and that has helped tremendously. I thought it wasn't supposed to have a big effect, but it may be tied into something else after one of the updates.

i actually removed package disabler and did a cache clean a week or so ago when i first started trying to diagnose the poor battery life. i didn't reinstall it and after a few days battery life went down the drain again. i don't think it's the app but you definitely should be careful of what you're disabling with it.
[Samsung Galaxy S7 Questions and Answers] theclaytons:
As a test, turn location from High to Battery saver and leave it for an hour. This has resolved my battery drain issue. not going to help when i need the GPS though!

Hello, can you show your battery usage?
[Samsung Galaxy S7 Questions and Answers] Rlin5741:
There was a recent (May 6) update on VZ to APD2. So far I have had better battery life, about 50-100% higher screen on time for a given uptime (I.E. I am left with enough charge at the end of my typical day to run the screen non-stop and get 50-100% more SOT before draining battery).

For me, that is a movement from 2hrs SOT over 17 hrs and draining phone close to zero to having 20% left after 18 hrs and 2.25hrs SOT (my screen on discharge is 15-20% per hour, so I could get an extra hour or so of SOT).
[Samsung Galaxy S7 Questions and Answers] Rlin5741:
Screenshots.
[Samsung Galaxy S7 Questions and Answers] gleggie:
Just took the update, I'll give a couple cycles to see if battery improves.
[Samsung Galaxy S7 Questions and Answers] seanie2322:
I downgraded to March firmware the other day and happy to say I only lost 3% overnight the device was in deep sleep for 8 hours and I'm currently going on 5 hours SOT with 20 hours on the battery. So any users experiencing issues after the April update I'd recommend ye downgrade until a new update comes out hopefully fixing the problem.

No more android system eating my idle battery ?
[Samsung Galaxy S7 Questions and Answers] stevevetter:
took the May VZW update

It's only been one day of medium usage, but it seems to have dramatically improved battery life. Android system is no longer completely dominating the battery usage and was just under Google Play Services until I started using the phone more and then SOT and calls started rising (but never eclipsing Play Services and then Android system).
[Samsung Galaxy S7 Questions and Answers] oll0:
Did you simply factory reset from within Android or did you do it from the recovery? Does it matter? My S7 is completely stock (W8, no root). Hoping it would help in my case as well.
[Samsung Galaxy S7 Questions and Answers] osomy:
From recovery.
[Samsung Galaxy S7 Questions and Answers] oll0:

Yeah, seems like every day nothing gets better. I'm still pissed that my co-workers LG G4 gets CRAZY battery life and he streams music from it all morning and only loses like 4-5% and I'm down to 75% by lunch (unplug at 8:30am and check around noon).

On the APE9 firmware and Android System still hogs battery. I did a full reset but it doesn't help.

Samsung service center says it's normal and this is on 3G. On 4G my phone heats up to 42 degrees Celsius and the battery lasts half the time.
[Samsung Galaxy S7 Questions and Answers] Cinco5:
My drain is caused by Bluetooth.

When it's on (connected or not, nearby device finding on or off) I burn 5-7%/hr idle. When it's off, 1% or less. I've done enough 2-3 day tests to be confident that this is it for me.

Anyone have any similar behavior?
[Samsung Galaxy S7 Questions and Answers] meboy:
Already reported that lots with the issue don't have Bluetooth.

Might be a thing. Just not an everybody thing.

I killed the GATTService under Bluetooth Share (in developer mode) and things are looking way up. I have no idea what app is starting that service though...
[Samsung Galaxy S7 Questions and Answers] s629c:
http://www.electronicsweekly.com/blogs/eyes-on-android/what-is/what-is-a-gatt-service-2013-08/

It's not an AT&T service. It's what they call Bluetooth low energy services I think. You can check the article for yourself
[Samsung Galaxy S7 Questions and Answers] Cinco5:
Oh yeah, I know exactly what GATTService is -- by killing it manually I've gone from about 5%hr standby to 1%, and screen and cell pull the most power now, not Android System or OS.
[Samsung Galaxy S7 Questions and Answers] s629c:
Sorry i misinterpreted what you said. So by killing it, does it affect using Bluetooth?
[Samsung Galaxy S7 Questions and Answers] Cinco5:
No worries -- Yes, killing it changes my power usage to something much more reasonable, and doesnt seem to affect Bluetooth devices. I will caveat this by saying I really only use BT in my cars for audio, and with the occasional speaker/headset for music and calls. I dont have any fancy fitness devices or watches, so who knows what it'll do to those guys.
[Samsung Galaxy S7 Questions and Answers] oll0:
That is very interesting. Can I kill the GATTservice on a non rooted device? How would I go abouts that?
[Samsung Galaxy S7 Questions and Answers] slayer03:
Settings ->Developer options -> running services -> Bluetooth Share and then STOP the service.

If you don't have the developer option:

Settings -> about device -> software info. Tap several times on the build number, developer mode will be unlock.

No root needed.
[Samsung Galaxy S7 Questions and Answers] oll0:
Oh alright I didn't find it in the running services earlier. It was there now. Looks like it doesn't restart itself. Sweet!
[Samsung Galaxy S7 Questions and Answers] malek777:
I also have the w8 and Android system is still too high. I use to have it at the bottom of the list at 7% but after the update it's always right after screen and at 20%. I did flash the previous firmware from February but as soon as the phone boots up it will automatically prompt you to update to the April one. Not to mention the previous firmware caused alot of reboots.
