So weird thing today. I got my VR crap last night so I enabled everything (from package disabler). Kept the usual stuff off in the normal settings and now getting way better battery! What the hell is going on?
[Samsung Galaxy S7 Questions and Answers] Cinco5:
Bummer, I had a pretty dramatic change when I turned it off. Cant say we didnt try....
[Samsung Galaxy S7 Questions and Answers] oll0:
I did too, just for the first cycle though.
[Samsung Galaxy S7 Questions and Answers] Cinco5:
And you're sure it stayed off? It returns on a reboot or if you cycle the Bluetooth power.
[Samsung Galaxy S7 Questions and Answers] oll0:
Yup, kept checking during the day.
[Samsung Galaxy S7 Questions and Answers] km8j:
There is no such thing as conditioning lithium batteries. What evidence do you have to support fast charging is causing an issue? Seems not related since android system is actually reporting very high usage. This isn't disappearing battery.
[Samsung Galaxy S7 Questions and Answers] sling:
I never suggested battery was root cause , I just added battery tip.

New battery's....any battery that hasn't been tapped needs some cool steady full charges before abused.

Fast charging hot boxes thus diminishing longevity swelling etc any battery.

Put 2 in 2 together only makes sense.....or something like that

Anyway I'm taking another vaca from xda , good luck hopefully your issue will be resolved soon

Adding.

S7 is great device coming from S5 Major props to Samsung

I haven't tried updating play services yet as I've been testing with VoLTE disabled today. Seems to have shaved 15% off of the Android System drain but that's still 35% drain due to Android System and OS.
[Samsung Galaxy S7 Questions and Answers] km8j:
Will be hard to attribute to VoLTE without a LOT of testing and comparing trends.
[Samsung Galaxy S7 Questions and Answers] supernova_00:
I completely agree! I just wanted to put it out there that the ONLY thing I changed after consistently having those drain 50% on Tuesday, Wednesday, and Thursday. BUT I'm also connected to LTE today whereas on those days I had just plain 4G. I'll have to wait until Monday to see if there is a difference at work with VoLTE disabled.
[Samsung Galaxy S7 Questions and Answers] LuigiBull23:
Only lost 3% over a 10 hour period on idle. We'll see how the rest of my cycle goes.
[Samsung Galaxy S7 Questions and Answers] Ramondel:
What have done to phone?
[Samsung Galaxy S7 Questions and Answers] LuigiBull23:
WiFi: Off

Location: OFF

Bluetooth: OFF

NFC: OFF

Nearby device scanning: OFF

All Smart/Gesture features: OFF

Disabled backlight keys with "Galaxy Button Lights" app

Greenified some apps

Disabled the following packages with "Package Disabler Pro".
[Samsung Galaxy S7 Questions and Answers] ToastyZ71:
Holy cow, you've pretty much crippled your phone!
[Samsung Galaxy S7 Questions and Answers] LuigiBull23:
LOL no I didn't. I only disabled the features and packages I know I won't be using and they're nothing that can actually harm the device.
[Samsung Galaxy S7 Questions and Answers] ToastyZ71:
I guess we can chalk that up to everybody using different things :)

I'll be using Tasker to schedule my wifi/BT time, and screen brightness based on power, that will help some.
[Samsung Galaxy S7 Questions and Answers] km8j:
Yea you've basically disabled every feature, app and component of the phone lol. Unfortunately we dont know which of those is actually the android system culprit
[Samsung Galaxy S7 Questions and Answers] LuigiBull23:
Again, I only disabled what I don't use. I didn't disable every feature, app, and component. It may appear that way but that's just because there's a sh*t ton of bloat on the device. If you use "Package Disabler Pro" on this phone you'll find that the apps/services I've disabled doesn't even compare to what is actually available to disable, which is just about everything.

Try it out and you'll see. I only disabled the unnecessary packages, nothing that can potentially harm my device. There are other users around the S7 forums who have disabled way more packages than me. So... you should probably take this matter up with them. Lol

EDIT: Here's just one example. I wouldn't disable nearly as much as this guy did. I'm somewhat surprised he isn't experiencing any issues.

[Samsung Galaxy S7 Questions and Answers] supernova_00:
Alright so I re-enabled VoLTE today and Android System is back to using 30% with basically no change in Android OS at 17%. So for me VoLTE is definitely causing between 10-15% drain. Now to figure out why Android System and OS are still causing a 30% drain. Down from almost 50% but I'm still not happy with those two eating over a 1/4 of my battery for nothing!
[Samsung Galaxy S7 Questions and Answers] osiris355:
This usage is too high. I would recommend clearing the cache from recovery or just wait until an update comes. I had something similar in my 5x and this fixed it for me.

Sometimes crappy google play services updates get rolled out and they get cleared up with silent updates as well.
[Samsung Galaxy S7 Questions and Answers] supernova_00:
I just sideloaded the latest update for play services from 8.4.* to 8.7.03 so we'll see how that goes
[Samsung Galaxy S7 Questions and Answers] km8j:
This do anything for you? I'm running out of ideas
[Samsung Galaxy S7 Questions and Answers] supernova_00:
I haven't noticed any changes whatsoever

[Samsung Galaxy S7 Questions and Answers] thunderroid:
I am starting to loose all hope on Android.
[Samsung Galaxy S7 Questions and Answers] Cinco5:
That sucks. Onto the next thing.

So the reason I was drawn towards that service is that it was running more than the other BT services. At the time, all of the BT services showed a running time of 20-something minutes, and the GATTService had been running for an hour. That seemed strange to me, so I killed it to see what happened.

Maybe there are more rogue services out there? I havent looked myself.
[Samsung Galaxy S7 Questions and Answers] slayer03:
Few days ago I tried to stop the GATTService. It was a success. I had 3-4 hours SoT, and after stop the service 5-6 hours SoT.

But after one day, I noticed the battery became like before, I checked and it was GATTService which was launched again. On my phone, from time to time the service launches by itself I don't know why. Because of that, this trick is less efficient than expected.
[Samsung Galaxy S7 Questions and Answers] oll0:
GATTservice was off all day. 3.5h SOT. Android system consumed over 600mAh. I don't understand the day to day variance
[Samsung Galaxy S7 Questions and Answers] coringabrazil:
I've seen that whenever I'm outside on mobile data my Android SO sucks my battery dry, using too much mobile data and keeping my phone wake for a long time, but that does not happen when I'm on WiFi. I'll post screenshot later

Going to try a factory reset and rebuild what I have. Will test performance and see if it helps on the new updates (TMO).
[Samsung Galaxy S7 Questions and Answers] mmorabe:
Haven't seen a huge improvement, but roommate just got the Verizon version and has 1 day+ of usage time vs my 17 hours estimated -_- Maybe it's just app related somewhere on TMO's version.
[Samsung Galaxy S7 Questions and Answers] Cinco5:
I had to replace mine under warranty (power button mushy) and I got the replacement with APB4, and I've had fantastic battery life. I've turned off update notifications so I can stick with this one until the problem is solved.

I'm genuinely convinced that the newer versions (APD and on) have something wrong with them.

If you can roll back, do it. Not sure how or if its possible with the Verizon version.
[Samsung Galaxy S7 Questions and Answers] osomy:
I've found this https://www.reddit.com/r/Android/comments/4nzijf/googles_backup_my_data_preventing_doze_and/

Yesterday I’ve turned off google backup and battery life seems much better. Haven’t done any tests yet but just to let you know since this battery life on S7 is frustrating after first phone update.
[Samsung Galaxy S7 Questions and Answers] Mamlo:
I had same issue with bad battery life after last android update (Exynos version). I installed BetterBatterStas and i was easy to find that *backup* keeps my phone awake whole time. In battery usage Android system was 50%+. After disabling "back up my data" i'm running 3rd day without charging (3.5h display time) and my battery is still above 20%.
[Samsung Galaxy S7 Questions and Answers] mmorabe:
Definitely trying this out for the next few days.

What are the big losses by turning this off though? Probably harder to restore to a new phone I assume?
[Samsung Galaxy S7 Questions and Answers] Woodfighter:
My biggest user always is the Android System. The stay awake times are virtually all day (8-12 hours). I have tried and tried to figure out what is keeping the system awake.
[Samsung Galaxy S7 Questions and Answers] mobrol:
Where did you find this option?
[Samsung Galaxy S7 Questions and Answers] Mamlo:
Settings -> Backup and reset -> "Google account" Back up my data -> OFF
[Samsung Galaxy S7 Questions and Answers] Woodfighter:
I turned my google backups off this morning and I am still showing under Android System that the phone has be awake 6 plus hours and computer power usage is 149.
[Samsung Galaxy S7 Questions and Answers] meboy:
There is no fix. People have tried everything at this point.

Just go back to LP.

I wasted soo much time on this and should have given up much sooner.

Nothing about MM is worth it on the device.
[Samsung Galaxy S7 Questions and Answers] Doofy911:
Possible Solution to the DRAIN!

Ok, so I've had the same issues as you. My findings are as per Gsam Battery Monitor:

1. High Android OS and Android System usage~ 20-30%

2. High Phone Radio ~ 40% at times

3. Overnight drain of at least 4% (standby drain)

4. Screen usage 'while off' higher than 'while on'

This was frustrating and is as mentioned by other users to be a bug from updates and related to charging.

SOLUTION:

Today Gsam reports my Android OS and Android System usage and Phone Radio at 10% and below.

All i did was...

1. Let it drain to about 90% after charge.

2. Restart the phone.

3. Then plug in the micro USB to USB connector (the one that comes with the phone) with a flash drive attached and play a song/short video.

4. Unplug and enjoy great battery life. ;)

This worked for me so it's worth a try. Will test a full charge soon and hopefully it doesn't require the steps above every time to stop the drain. :rolleyes:

btw I'm NOT rooted, using LTE.........wifi,bluetooth, AOD and locations all off.
[Samsung Galaxy S7 Questions and Answers] L4s7Re4lG4mer:
LoL your fix is like i went out of the house and took 3 times right and then 2 times left and BOOM the drain is fixed. LoL :eek:
[Samsung Galaxy S7 Questions and Answers] Doofy911:
Well it works, ain't Rocket science.

Seems like powering a flash drive through the same charging port does something with the OS :good::good:
[Samsung Galaxy S7 Questions and Answers] murattiss:
Try to restart your phone after unplugging from charger, will make the same effect.

Happened to me also some while ago as cpu was not entering deep sleep after unplugging from charger, a reboot was fixing it.

I did not make anything but now it does not happen anymore and cpu is entering deep sleep after charging without reboot .
[Samsung Galaxy S7 Questions and Answers] Doofy911:
I noticed that yesterday too. The drain has subsided, but checking Gsam again shows that Doze is not active.

So better battery life without Doze? Is Doze working in reverse?......Something is off there :(:(:eek::eek:
[Samsung Galaxy S7 Questions and Answers] Imraan albeerdy:
I have the same problem and i kinda got used to it after a month using the phone. Still gets me past a whole day of battery usage and around 6hr-7hr of on screen.
[Samsung Galaxy S7 Questions and Answers] LuigiBull23:
Why?
[Samsung Galaxy S7 Questions and Answers] PunishedSnake:
Luckily theres other OEMs to try
[Samsung Galaxy S7 Questions and Answers] osiris355:
You sounds like you want to lose hope. If there is stand by drain issues with an S7 thats a touchwiz problem. My Nexus 5x barely drips battery life.
[Samsung Galaxy S7 Questions and Answers] nadrojjordan:
Android System and Android OS are usually in my top processes for battery usage as well, but I'm not experiencing poor battery performance. Is it possible that the screen on the S7 is just that much more efficient than the screens in past devices?

Yesterday I used approximately 4 hours of screen on time and the screen only consumed 590 mAh. With a screen that efficient, it would actually make sense that all of the background services would take more than that, so perhaps Android OS and Android System should be above the screen in the list?

I can't speak for everyone's experience, but it's just a thought.
[Samsung Galaxy S7 Questions and Answers] insang-droid:
Don't believe what you see on the battery stat page. It says RADIO app used 883mah of my battery which is 30% of 3000mah capacity, but I still have 85% left.. And it doesn't count for other Android and screen.. And other **** that runs. My guess the battery usage reporting is all out of whack.

My suggestiom is Stop paying attention to other stuff and just focus on on screen time since thats what matters the most.

Take some bloat out with package disabler if it makes you feel better, but otherwise enjoy a great phone..
[Samsung Galaxy S7 Questions and Answers] nadrojjordan:
Wow, yeah, the math definitely doesn't work out on that! I wonder if that metric is showing more than since the phone was last charged? Certainly explains why I'm seeing strange numbers.

Either way, I totally agree -- I'm really enjoying the S7 and thankfully I'm getting very good battery life and not having any issues whatsoever. I came from a Nexus 5X and my S7 blows my 5X out of the water for battery life. It isn't even close. All of my settings are on too (Location, Bluetooth, Wifi, etc). Hopefully the experience improves for others in this thread.
[Samsung Galaxy S7 Questions and Answers] km8j:
Did you charge your phone in between, not until 100%? The stats are definitely accurate and there is definitely a bug in android system usage.
[Samsung Galaxy S7 Questions and Answers] AndreiLux:
The battery stats are a load of bullshít. 90% of the time somebody on a device complains about some perceived drain it's most likely just because the base configuration settings which are used by the OS to calculate battery statistics (yes, it's an calculated estimate) are wrongly set up.
[Samsung Galaxy S7 Questions and Answers] insang-droid:
No charge in between. It's from 100%. My guess is that Android system includes other processes and services same with Android OS. Since each app can use uses many different services I highly doubt there's a good way to show how much of the battery it's using.

Just my guess though.. But ya.. Forget the stats.. Enjoy the phone unless you're really getting bad battery life.

BTW I already tried factory reset from recovery and it did nothing..
[Samsung Galaxy S7 Questions and Answers] mnphonguy1:
I keep seeing KNOW causing a lot of battery drain (or at least supposedly). It looks like that battery drain is part of my Android System usage which is always #1 on my list of battery hogs. I can't find a way to turn it off or uninstall. Can someone help me or am i just assuming there is a problem with this app and there isnt?
[Samsung Galaxy S7 Questions and Answers] freebee269:
did you mean knox? if so then we have to wait for root to get rid of knox.
[Samsung Galaxy S7 Questions and Answers] mnphonguy1:
Yes I did sorry. Would package Disabler do it?
[Samsung Galaxy S7 Questions and Answers] freebee269:
it disables 2 things for knox but knox has much more than just those 2 things. i have them disabled and i still see knox part of android system usage. you need root to get rid of all those other things.
[Samsung Galaxy S7 Questions and Answers] mnphonguy1:
Crap well it should help right? Is there a list somewhere that recommends what to disable using package disabler?

Thanks for your help.
[Samsung Galaxy S7 Questions and Answers] rogerchew:
Android system and Android OS eating up 40% of my battery usage. What the heck?! In my Nexus days screen was always the #1 battery use. Why is this not the case on the galaxy? What are the steps to root cause this? I know it can't be normal.
[Samsung Galaxy S7 Questions and Answers] supercakefish:
So rather than Android System eating up my battery, I've got Play Services chewing it up instead.

Any ideas what could be the culprit?

[Samsung Galaxy S7 Questions and Answers] km8j:
Over what period of time for you? The battery stats aren't wrong despite what people say.
[Samsung Galaxy S7 Questions and Answers] Sfkn2:
I hope it's reporting incorrectly.
[Samsung Galaxy S7 Questions and Answers] km8j:
It's not
[Samsung Galaxy S7 Questions and Answers] Synyster06Gates:
Why would you hope that? :eek:

If it is an actual problem and it gets fixed, the battery life on the phone would be absolutely incredible.
[Samsung Galaxy S7 Questions and Answers] km8j:
I might be onto something.... Does anyone else with the Android system bug notice that in data usage, Android system is also using an absurd amount of data? I'm seeing 250mb per day roughly... What would this be?

Nope.

[Samsung Galaxy S7 Questions and Answers] supercakefish:
Oh no, my Exynos unit has started suffering from it. It was fine until I laid it down last night. Something drained it overnight, resulting in Android System going haywire.

Edit: found the culprits!
[Samsung Galaxy S7 Questions and Answers] km8j:
These are not the culprit. All Android system entries show the same usage. They are bundled together
[Samsung Galaxy S7 Questions and Answers] MrFriendlyAssman:
Good battery

I don't have an issue when i leave my phone screen off, if you use it for short period with full brightness + needs to connect to 4g constantly for your activity.

This wil drain the battery fast.

My battery usage 5 hours from last fully charged:

Now i'm at 95%

Screen:

58%

Cell standby:

41%

Device idle:

20%

Estimated time remaining is:

14h 15m

I'm not on my phone constantly, maybe that's why the battery drains slower.

No. It's the opposite. Standby time suck is bad for us

---------- Post added at 06:19 PM ---------- Previous post was at 06:18 PM ----------

No
[Samsung Galaxy S7 Questions and Answers] Sfkn2:
It's because I'm pulling 9 hours SOT even with Android System and Android OS at 50%. You think this phone is capable of 18 hours SOT? That would be weeks worth of standby time. That's why I'm thinking it's a reporting error that can be fixed on software side.
[Samsung Galaxy S7 Questions and Answers] LuigiBull23:
Fantastic battery life on my end. Doesn't get any better than this. :)

[Samsung Galaxy S7 Questions and Answers] km8j:
That is legendary battery. Over what time span? Wonder how much different S7 would be in YOUR situation/usage given smaller battery but smaller screen.
[Samsung Galaxy S7 Questions and Answers] km8j:
Well the good and the bad is after a fresh wipe and doing absolutely nothing to the phone, I had no android system usage. As soon as I started adding accounts and downloaded maybe 20% of my apps, Android System went through the roof.... So there must be something we can turn off?
[Samsung Galaxy S7 Questions and Answers] Namtaru:
I know some people in here are saying "oh it's fine, i still get great battery life". I can tell you there is in fact a problem with some units.

This is my wifes, with 2.5 hours of screen on time.

10 hours of battery life is on a legendary level of ****ty.
[Samsung Galaxy S7 Questions and Answers] km8j:
Yea I agree. My usage is basically identical to you and about the same battery life.
[Samsung Galaxy S7 Questions and Answers] Sfkn2:
Is that the type of reception that phone sees all day? One or two bars? I'm constantly at 5 bars being in the middle of Seattle proper, so reception is never an issue.

And my charges typically last about 50 hours.
[Samsung Galaxy S7 Questions and Answers] km8j:
At least in my case, it is not a reception issue. That also should show under cell signal, not android system.
[Samsung Galaxy S7 Questions and Answers] Namtaru:
It's a bit deceiving because I have a Samsung Wireless Network Extender in my house (which is another question, on all of my other android phones when at home they have a little house icon with bars over it to let me know it's connected to the extender but the S7 doesn't have that icon. It's not a marshmallow thing because my G3 has the icon too).

As I type this I'm starting to wonder if its draining because it's not connecting to the extender? Which would make no sense, because I've used the phone in my basement multiple times where there is 0 tower cignal and my calls have been perfect, usually meaning it's connected to the extender.

Sorry for the long winded answer, but the short answer SHOULD be that the signal strength shouldn't matter in my case (when at home), it hasn't for any of my other Android phones.

The screenshots above were taken over the weekend of which was entirely spent at home.
[Samsung Galaxy S7 Questions and Answers] km8j:
Signal isn't your issue.

[Samsung Galaxy S7 Questions and Answers] Sfkn2:
Try a factory reset. This does not look right at all.
[Samsung Galaxy S7 Questions and Answers] km8j:
Wont do anything.
[Samsung Galaxy S7 Questions and Answers] Sfkn2:
That chart looks REALLY bad. I mean, screen isn't even there as a usage. The only thing I can think of is Google syncs getting caught up. For example, if Google Photo fails to sync, it tries repeatedly. This will definitely eat your battery, especially if you're in an area with poor reception.

Try turning off syncs?
[Samsung Galaxy S7 Questions and Answers] km8j:
Would those show under Android System though?
