[Samsung Galaxy S7 Edge Questions and Answers] xocomaox:
Android System reads higher on some phone models than others. It has to do with how the firmware (rom) is made/configured.

You should not get more than 0.25%/hour idle drain in deep sleep (unless you have Always-On Display turned on, then expect 0.9%-1%/hour drain during deep sleep).

As far as screen on time goes, this is affected by many things (applications used, brightness setting, daytime hours vs night time hours, mostly WiFi or only LTE, etc).

I can tell you with my Verizon S7e I get some great numbers, even when Android System is reading at 20-30% usage.

Check my screenshot attached, at 50% battery. This is with auto brightness, mostly on WiFi, about an hour of gaming, the rest of the time is YouTube, Hangouts chat and web browsing. A little texting with sound notification, about 50 messages). Mostly indoors so moderate lighting and some later nighttime lighting. If I recall, Android System usage was listing at around 28%.

EDIT: I wanted to stress that gaming has always taken a big hit on battery life for my past phones. Not so with the S7! It handles gaming very well and the battery life isn't crippled. I should note the top four games I play are Hero Siege, Downwell, Crashlands and Rust Bucket.

I have trouble going into deep sleep too. I tried this method but I didn't see any red flags in the running services :(
[Samsung Galaxy S7 Edge Questions and Answers] russellsidhu:
Coming from a new Nexus 6p it says mine is under 5% which makes it ****ing unbelievable
[Samsung Galaxy S7 Edge Questions and Answers] TheWu-Wei:
My battery life has improved as well, despite my whinging about a reset not helping. I actually saw over 7.5 hours of doze time. I'm just trying to understand why Android System is still topping my charts...

My reaction was just that - a reaction to still seeing that at the top. And given that I've spent the last while restoring my apps and data (and doing another update from VZW), I'm going to wait a couple of days and see what kind of results I get with more typical use.
[Samsung Galaxy S7 Edge Questions and Answers] km8j:
Rebloating did nothing for me. I debloated again
[Samsung Galaxy S7 Edge Questions and Answers] Ghstudent:
Debloating only affects your battery if you used the app and used their debloat function, normal debloating does nothing.
[Samsung Galaxy S7 Edge Questions and Answers] km8j:
Not true really. If apps are being used in the background, they consume battery. Killing them stops this
[Samsung Galaxy S7 Edge Questions and Answers] Naemion:
Unless there are other process that are trying to find those running apps and can't so theyear search constantly for them by repeating the same code over and over again.
[Samsung Galaxy S7 Edge Questions and Answers] km8j:
People debloat all the time. I understand what you are saying but I doubt that is causing an issue.
[Samsung Galaxy S7 Edge Questions and Answers] whittikins:
I think he meant that it only negatively affects battery if you use the app's "debloat" feature which disables some packages that it shouldn't (ones the OS might be trying to find and causing drain).

I could be wrong, but that's how I read it.
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
Maybe. Maybe not. I have seen many people say they actually got worse battery life after deleting the bloatware packages. I myself experienced this issue. I haven't tried pinning down which package it is but I for the past 5 days my battery life has been averaging 2 days off charger with 8 hours SOT. That's without removing a single package.
[Samsung Galaxy S7 Edge Questions and Answers] Ghstudent:
These guys understand what I'm talking about. normal debloating is gonna save minimal battery life if you haven't used the app before because it isn't going to have the app initialized and with no accounts or settings input that app isn't likely to run (not to say that they always won't) a good example of this is the Facebook app; It's preloaded onto the device, however it isn't going to constantly pull updates from the app without an account to sync it to. However, if you disable a system process (let's say com.Google.example) and the system relies on this process to function and it isn't vital to the OS running (systemUI.APK for example) then the build.prop is going to constantly return an error value while trying to compile. And since build.prop isn't very fond of the 'else' clause it's going to constantly attempt to run that line of code over and over again until it gets a response (which it won't as long as that package is disabled.) This would actually cause your OS drain to increase.
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
By the way what is the System UI app that is always running in the background?
[Samsung Galaxy S7 Edge Questions and Answers] Ghstudent:
Framework-res.apk
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
Do you know exactly what it does?
[Samsung Galaxy S7 Edge Questions and Answers] Naemion:
From what I understand it's part of the basic operating system.
[Samsung Galaxy S7 Edge Questions and Answers] Ghstudent:
I've modified it quite a bit on previous phones, so yeah. It's what displays everything from status bar icons to quick settings to toggles

It is, but this is probably the most broad answer you could use to explain it.
[Samsung Galaxy S7 Edge Questions and Answers] TheWu-Wei:
Well, after a day or so of something approaching "normal usage," I'd say the clear-cache-factory-reset has helped me a lot. Android System is down to 14% according to GSam, and seems to be consistently dropping.
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
Did you remember to turn off the background reporting to Google and Samsung? Also turn off WiFi and Bluetooth scanning.
[Samsung Galaxy S7 Edge Questions and Answers] TheWu-Wei:
Yup. I turned off everything I could in terms of reporting, and I don't see how WiFi or Bluetooth can contribute to the accuracy of my location so I never use that option.
[Samsung Galaxy S7 Edge Questions and Answers] km8j:
It finds local devices that report their location and uses that.
[Samsung Galaxy S7 Edge Questions and Answers] TheWu-Wei:
I understand the premise, but I'm a little more concerned about security, etc. And most GPS locates these days are within 1-3 m. That's good enough for me to get weather forecasts. [emoji6]
[Samsung Galaxy S7 Edge Questions and Answers] msage:
Did you perform the reset via the settings menu or the boot menu where the cache clear option is located?
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
Yup....Did it through recovery.
[Samsung Galaxy S7 Edge Questions and Answers] msage:
Thank you. Think I'll be trying this real soon. I tried all the other suggestions you gave outside of the reset and Android System usage actually went higher so hopefully with the reset I can get close to your results. Maybe the menu options for disabling the Samsung and Google reporting aren't exactly the same as the options provided during initial setup. Thanks a lot for your help man, it's appreciated.
[Samsung Galaxy S7 Edge Questions and Answers] km8j:
I'm still stuck at around 4.5 hours battery life. Grrr
[Samsung Galaxy S7 Edge Questions and Answers] TheWu-Wei:
Yes, I did this through recovery too.
[Samsung Galaxy S7 Edge Questions and Answers] Naemion:
Pretty happy with mine right now. Yes I know the android system is high but I have only used 13% of my battery. As I use more it should settle down.
[Samsung Galaxy S7 Edge Questions and Answers] Pilz:
Judging by how early Samsung got the SD82 for testing in surprised they didn't address it.
[Samsung Galaxy S7 Edge Questions and Answers] johanbiff:
will get my EU model (exynos) next week. I feel bad for you SD820 guys :\ hope they fix it with a update.
[Samsung Galaxy S7 Edge Questions and Answers] dodgeboy:
I think it might be WiFi Calling. It's still very early in the test, but disabling it does seem to have reduced the amount of "android system" drain. I'm going to try to disable WiFi Calling for a couple days and see if that helps. I had it enabled, but preferred cellular, so I haven't actually used wifi calling since I got the phone.
[Samsung Galaxy S7 Edge Questions and Answers] GiancarloMorr24:
I can attest that it didn't help me. I've had WiFi Calling off since first boot up and my Android System is still no 1 battery hog for a given charge cycle.
[Samsung Galaxy S7 Edge Questions and Answers] Dr. Fed:
Thanks. I hope the cell-standby drain gets fixed for the Exynos variant.

I'm pretty sure this is people closing apps out and the CPU reoppening. I don't have any problem with the high System usage or battery life so long as I let the system deal with priotitization and ram usage.
[Samsung Galaxy S7 Edge Questions and Answers] takethebox:
I'm not one of those people. I never close apps and let's Android handle that. Mine has been as high as 36%
[Samsung Galaxy S7 Edge Questions and Answers] GiancarloMorr24:
Count me as one of those who rarely if ever closes out apps. My Android System battery usage looks a lot like yours.
[Samsung Galaxy S7 Edge Questions and Answers] RnRexpress3423:
So your not using the recent tab button to close all of your apps? You just leave them all running??

I'm having high android system and android OS usage while on Nova prime.
[Samsung Galaxy S7 Edge Questions and Answers] GiancarloMorr24:
This seems to be pretty consistent across all SD820 variants on TMobile. Even with that, battery life is impressive.
[Samsung Galaxy S7 Edge Questions and Answers] msage:
It's definitely better than my V10 but I have to say personally I'm not impressed and was expecting much more based on some reports out there. So far it seems to fall in line with my Note 4. I'm wondering if there is an OTA planned for release day or if Samsung acknowledges a problem.
[Samsung Galaxy S7 Edge Questions and Answers] GiancarloMorr24:
Only time will tell, really.
[Samsung Galaxy S7 Edge Questions and Answers] Dr. Fed:
Why would you want to close out all your apps all the time?

---------- Post added at 04:36 PM ---------- Previous post was at 04:32 PM ----------

Yeah, on my last charge cycle I got over 6 hrs SOT. I'm happy with that. I feel like things will only get better with future updates or even just future info on how to decrease the Android System usage.
[Samsung Galaxy S7 Edge Questions and Answers] vivelafrance:
I too have had this issue with Android System but only since I bought the Huawei Android watch. Maybe it's the Bluetooth connected to the watch that does that, but it shouldn't, Bluetooth doesn't take that much battery...
[Samsung Galaxy S7 Edge Questions and Answers] idksomuch:
Android OS/System is always at the top of my battery chart but it doesn't seem to affect battery life (at least none that I notice). "Screen" is always the third, fourth, or even 5th down on what's taking up battery with Android System, Android OS, Youtube, occassionally Adguard if I turn it on, taking up the top spots.
[Samsung Galaxy S7 Edge Questions and Answers] cepheid46e2:
Correct. A couple of things I tried that actually DECREASED battery life were: Actively closing out apps and using the "Hibernate System Apps" in Greenify. Both of those increased battery drain for me. If I left the apps running and let the system decide what to close my battery life maxed itself out at around 8h SOT (web surfing, no video games or playback). Not sure if it's Marshmallow or TW.

Also look at your Android Systems through GSam rather than through the ROM battery parser.

[Samsung Galaxy S7 Edge Questions and Answers] TheWu-Wei:
No clue whether this is having a significant impact, but...

I have tons of photos on my SD card. I've noticed the last few times I've opened Gallery, I get a little popup telling me "An event has been created" based on dates and faces in pictures. Obviously the system is scanning images in the background, so I disabled automatic event creation. Will see if that helps at all.

To do so, open Gallery, switch from Time view to Events view, tap More, Event settings, disable Auto create events.

jrwingate6 has a thread that provides a step by step, but basically I made sure I was comfortable with having local copies of what I need on my SD card (cleared out device storage of important docs, pics, etc as they will be wiped); removed my Google account, rebooted into recovery (power+volume up+home key); cleared cache, factory reset, reboot; opted out of any reporting options whatsoever during setup.

I use a "dummy" Google account strictly for Play store and device backups. Therefore, I didn't add any accounts during setup. Just hit skip on everything. That's a quirk of my setup, but I wanted to mention it.

I might have missed something, so do double check against jrwingate6's thread as well. Good luck.

I replied before about how I think I found my problem with my phone not going into deep sleep.but now it's happening again with the process of contacts in the running services.

Just disable it, I wanted to make sure that it wasn't doing something vital with your sim card but if it is still running then it isn't reliant on your sim. I'm assuming that it has something to do with adding new phone numbers to the device but if your sim is functioning properly already then I would disable it.

[Samsung Galaxy S7 Edge Questions and Answers] pradeepd:
May be this????

I think I might have found the issue. I don't want to conclude but please try this and see what's happening. There are 3 processes (combined as Android System) that was taking the most of the battery. How to find?

1) To go settings -> smart manger -> RAM

2) Scroll to the bottom and you will see others. Expand that

3) You need to check on each process and you will see how much battery was used by this process.

4) In my case, there was the 'Software Update" which took 15%, Remote Controls -> 15% and com.qualcomm.atfwd -15%.

5) So went to Package Disabler and just disabled the "Software Update" as well "Remote Controls"

I'm seeing much better drain and avg/usage on GSAM.

I don't want to conclude, but please check yours and post the results.
[Samsung Galaxy S7 Edge Questions and Answers] Ghstudent:
It might, but you won't know until you try it.

---------- Post added at 11:49 PM ---------- Previous post was at 11:48 PM ----------

It depends on whether the app is a system dependent, which I don't think it is.
[Samsung Galaxy S7 Edge Questions and Answers] TheWu-Wei:
Not all users have Smart Manager available. Verizon customers, for example, do not see that on their devices.

Regardless, I will take a look at the processes you mentioned and see what I find.

Also, installing Package Disabler Pro triggers the Knox agreement (which I declined, and) which may be part of the problem as it mentions continuous security updates, etc

truly abysmal battery life

Hi guys, I'm been lurking for a while and finally made an account because of my SD820 S7 (tmobile). The battery life is on par with my years-old htc one m7, which is just embarrassing.

I've used package disabler, avoid advanced features like location services, push notifications, AOD, etc., and this is about what I've been dealing with. I've read through about 20 pages of this thread, it seems like the next move is to do a factory reset? Thanks, I appreciate any replies in advance. 2 hours of SOT (basic web browsing and messaging, 25% brightness) is seriously sh*t, I'm really anxious to get more out of my otherwise-great phone. :p

I just downloaded GSam to get better statistics, but clearly something is very wrong.

[Samsung Galaxy S7 Edge Questions and Answers] xocomaox:
More fantastic battery numbers on the Verizon S7e. Android system being the highest in the list isn't really a bad thing, and it just means that processes and tasks are getting lumped into it.
[Samsung Galaxy S7 Edge Questions and Answers] gettinwicked:
Just to add my 2 cents here, I don't think AOD has anything to do with battery drain at all, so enable it if you like it! I'm now getting close to 40 hours on my battery (Verizon), and I've never turned AOD off. I also haven't done a factory reset or wiped cache via recovery. Soooo, all the hoops some of you are jumping through I believe are unnecessary. I disabled a few apps in the app manager, turned off send security reports (the biggest improvement there), set location to GPS only as well as shut off WiFi and Bluetooth scanning, turned off scan for nearby devices, WiFi on when charging, and that's it.. I went from taking my phone off the charger at 6am it being below 20% at 5pm when I leave work, to now having around 40 hours battery. I also have bluetooth on always. Anyway, thanks to all who posted your findings, it has helped me get mine phone to a more than reasonable state of battery life.
