I install two OTA as well. I had amazing battery life until I installed the first OTA update from Verizon. My battery life used to be almost 2 days now its down to 22 hrs. I would really like to know how to revert a OTA update because i feel that is the reason my battery life is now cut in half.

B4 was the first one.

B5 was the second which was wifi fix.

-on Verizon S7 edge.
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
Do you have any packages disabled?
[Samsung Galaxy S7 Edge Questions and Answers] h.nocturna:
I don’t think it’s possible to downgrade from an OTA which is why many people who want to root their devices are recommending you stay away from OTAs until root is found.

Only way I can think of is replace/exchange the device through Verizon. Sorry

Anything obvious with what?

My phone is getting 101* degrees while charging is that normal? It's been doing it every time I put it to charge, BTW I have fast charge on.
[Samsung Galaxy S7 Edge Questions and Answers] Ghstudent:
First off: this has nothing to do with this forum, please post appropriately.

Second: it's not normal, but it's not uncommon. That usually indicates that you have an app running that is using a lot of the CPU.
[Samsung Galaxy S7 Edge Questions and Answers] lazard:
the phone does get pretty warm when fast charging.

I have a problem with Android OS not Android System nd i still don't know how to fix it
[Samsung Galaxy S7 Edge Questions and Answers] Naemion:
That is a byproduct of any type of charging. Just more noticeable with fast charging because there is a bigger exchange of power.
[Samsung Galaxy S7 Edge Questions and Answers] optimummind:
This is what I ended up having to do to get back my battery life after taking the update Sprint pushed out - a factory reset & wipe from within Recovery.
[Samsung Galaxy S7 Edge Questions and Answers] xocomaox:
This temperature is actually normal if you are using the stock charger and have not disabled Fast Charging in settings.

I have problem with my battery of my G935FD (Dual sim).

I have only 5H30 SOT in 13H30 hours on battery.

I'm far from a lot of people here....

I have made all these things :

3. Opt out of all background reporting to Google and Samsung. (Google Location is okay)

5. Turn off auto update in the pay store.

6. Disable any app you don't want in the application settings.

8. Set WiFi to sleep when the screen is off or stay awake only when charging.

9. Turn off WiFi and Bluetooth scanning.

10. turning off Google and Samsung background reporting

I have installed my phone with smart switch... And i don't made a factory reset before installing my phone the first time....

Also, as you can see on my screeshots, my wifi is all the time on although it has to be connected only when charging when the phone is on screen off...

HELP ME....

Just received a Tmobile Update for video recording fixes, Battery optimization, and performance enhancements, among other things. I wanted to upload the screenshot but got too excited and clicked install update lol.
[Samsung Galaxy S7 Edge Questions and Answers] jgodfrey82:
Also took the update today, 4-5hr SOT was my best before with all recommend adjustments
[Samsung Galaxy S7 Edge Questions and Answers] ReTro FuZe:
I get roughly 7 SOT already. I thought I was going to get 8 yesterday because I was at 50% with 4 hours of SOT, but then I eventually went to sleep and charged my phone overnight lol. If Android System and Android OS is indeed a culprit and not just a misread by the OS, and it gets fixed with this update, I'm golden, and I hope you all will be golden too. I don't know what your usage is throughout the day, but try my configuration that I posted a few posts back if it doesn't heavily conflict with what apps you use. The apps I have disabled are nothing of a game changer at all, just mainly useless apps, for me at least.
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
Let us know how it is after you run it through it's paces.
[Samsung Galaxy S7 Edge Questions and Answers] danon.brown:
Usually I would have android system at the top. It's only been about an hour off of the charger. Updated to C8 yesterday.

[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
How much screen on time is there?
[Samsung Galaxy S7 Edge Questions and Answers] xocomaox:
Here are the issues I see by looking at your screenshots alone without any knowledge of how you're using your phone:

1. You phone was held awake for almost 8 hours of your total 13.5 hours of use. This is far too high, something must be keeping it awake...

2. Your WiFi battery usage is abnormally high. Hopw is the WiFi setup in your area? Perhaps the signal is very weak or WiFi is keeping the phone awake longer than it has to? It might relate to number 1, above.
[Samsung Galaxy S7 Edge Questions and Answers] Eran Says:
T mobile pushed out an update this morning which seems to have fixed the issue. If course I've only been in this update for s few hours but it seems promising so far
[Samsung Galaxy S7 Edge Questions and Answers] km8j:
I enabled all my previously disabled bloat and am taking the update now... Here is to hoping for a fix. Going to charge to 100% and go completely stock without debloating to see what happens.
[Samsung Galaxy S7 Edge Questions and Answers] ilan78:
SO what do you think?

I have to make a factory reset???
[Samsung Galaxy S7 Edge Questions and Answers] geoff5093:
If you are getting 5h 30m of SOT, why are you complaining? Just because your use case doesn't match some odd ball 7 hours of SOT, doesn't mean yours is bad. I get around 3 hours SOT on my S7 Edge, because my use is different than yours.

Well, 5.5 out of those 8 hours was with his screen on. The other 2.5 hours could have been streaming music, background uploads, and other misc app syncing.
[Samsung Galaxy S7 Edge Questions and Answers] km8j:
The issue on our phones is CPU activity and drain constantly. I'm one of the people who averages 3 hours SOT of light use (we will see if the update fixes it) throughout the day. However, if I were to go straight through, I can get 5-6 hours SOT. Try and spread that out and no way, because I'm easily losing 600-900mah of battery throughout the day without my phone doing anything due to the bug.
[Samsung Galaxy S7 Edge Questions and Answers] xocomaox:
That is not how "Held Awake" works. It doesn't add SOT to that stat. For example, my SOT his higher than my Held Awake stat in GSam. Check after an hour of use and you will see the same.

His phone is definitely not acting right. It should have less battery consumption for WiFi radio.

---------- Post added at 07:33 PM ---------- Previous post was at 07:21 PM ----------

Again, check your WiFi signal strength to see what's going on there. Is it a notoriously weak signal?

Have you checked Advanced WiFi settings to see if Smart Network Switch is on/off? Keep WiFi on during sleep is on/off?
[Samsung Galaxy S7 Edge Questions and Answers] sitnamzug132:
The first couple of weeks after getting the phone (Sprint) my battery life was great... Now for some reason the battery life has taken a nose dive. Today my phone drained from 100 to 75% in about 5.5 hours and I barely used the device... Right now I'm at 30% with only 10 hours on battery and less than an hour screen on time and I've barely used the phone!

I have performed no debloat and no root., and I live/work in an area with strong signal. I'm not sure what changed, but it looks like my phone is just not going in to deepsleep for some reason and I have no idea what could be causing this.

I guess I could do a factory reset but I'm hesitant to do so because it might seem like everything is fixed at first but then in a couple weeks I could be right back with battery drain again out of no where. I guess it's worth a shot, but this has been a problem with every Galaxy phone I've ever owned (3, 5, now 7). I assumed Marshmallow would squash these issues... The frustration never ends!

Check the developer options and see what processes /services are running. Also make sure none of them say "restarting".

I keep all my wifi ,3g/4g bluetooh , nfc off and only turn it on when I need it, I have all sync items turned off and have nly disabled Facebook. I get great battery. Sometimes it sucks having to switch to the toggles to manually do things. But from and IT security side its also nice not being connected to the web 24 /7
[Samsung Galaxy S7 Edge Questions and Answers] meblah741:
Just to share what I've experienced over the last 3-4 days after experiencing battery drain. I disabled a bunch of crap using package Disabler pro. I also cleared cache and I used to have to clear it after recharging, however, recently I haven't had to do that. Don't know what exactly caused my held awake to be drastically lower but I won't complain about at this point. Standby drain is anywhere from 0.4 - 0.6% per hour. I have Wi-Fi off, Bluetooth always on, location high accuracy, WiFi and Bluetooth scanning off, Android and Samsung reporting off. On Verizon S7 edge.
[Samsung Galaxy S7 Edge Questions and Answers] howie411:
There is definitely something wrong. I have a Sprint S7 Edge (Which isn't really activated right now) and I have mobile turned off. I used it for about 5 minutes today and its been on battery for 14hs. And its at 55%

44% Android System

25% Android OS

6% Cell standby

5% device idle

3% screen

1-2% for a few other items.
[Samsung Galaxy S7 Edge Questions and Answers] sonhy:
try some automation apps like Llama and macrodroid, they toggle wifi and such for you when your conditions are meet, it should make life easy in some way for you.

also without root you can block all apps from internet access except those you want to have access, Apps like noroot firewall and such.

---------- Post added 5th April 2016 at 12:21 AM ---------- Previous post was 4th April 2016 at 11:50 PM ----------

maybe its the apps your installing that wake up regularly to access the internet, do you use a firewall? noroot firewall is quite easy to use, it asks you every time a new app wants internet access, and also logs all net access requests and so you can see which apps wake up to access internet and how often, e.g youtube constantly checks certain ip addresses all the time even though i dont use the app or give it internet access, you can then start disabling apps that you don't use, it may help with random wake ups and battery drain.
[Samsung Galaxy S7 Edge Questions and Answers] meblah741:
[MENTION=299752]sonhy[/MENTION] have you installed noroot firewall on your phone and if you have, 1)does it use up battery and 2) has it helped you with standby drain?

Thanks!
[Samsung Galaxy S7 Edge Questions and Answers] km8j:
I would assume those apps can hurt battery if an app is trying to call out to the internet and can't, it may keep trying
[Samsung Galaxy S7 Edge Questions and Answers] trantua4:
Just got an update from T-Mobile today. Before, Android System and Android OS were taking at least 25-40% EACH. I tried everything suggested besides for a reset, and no go. I didn't my settings after the update, and it seems to fix the problem.

Android System is at 15% and Android OS is at 12% with a much improved battery life.
[Samsung Galaxy S7 Edge Questions and Answers] sonhy:
yeah installed noroot firewall from day 1, before putting in the sim card I Bluetooth the apk over and install before phone gets internet access so the system cant get ads cache and stuff.

Im a heavy user and im shocked how long the battery lasts for me and how fast it recharges. I get over 4 hrs sot easy and about 15hrs of daily use but it depends how much in use gps and torrenting tv shows and such, i also use Macrodroid to check cell tower locations and auto toggle wifi Bluetooth and other hardware.

Overall i would not say i experience any unusual battery drain.

Noroot firewall is quite low on the battery usage list and I never see it unless i scroll down the list.

the firewall log helps to see which app is constantly requesting internet and then you decide to disable it or uninstall it, i haven't got root yet but i plan too.

I have everything blocked unless i know I need it.

here's my firewall block list, sorry its damn long :p

[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
Just to let those of you know who aren't on T-Mobile there is a light at the end of the tunnel. The update T-Mobile just pushed out today fixed the Android System battery drain. So far in 7 hours Android System is reporting 0% of the battery used.

I still have all diagnostic reporting turned off but I have been running the phone with no packages disabled. Before this update I had turned off the T-Mobile apk packages because they were running in the background but that also is no longer running.

Hopefully those of you who are on other networks get the update soon because it fixed more than just the Android System battery drain. The update also fixed screen sensitivity issues and toned down the haptic feedback. My palm resting against the edge of the display no longer registers as a touch nor does it cause the screen to go unresponsive. The phone just generally feels more responsive and I'm no longer getting lag in some games. It almost feels like the update has killed all of the unneeded background processes/services.

I was thinking about checking out the HTC 10 in a couple weeks but now I think I'm sticking with this phone.

Tonight I will leave the phone off of the charger and use it all day tomorrow so I can post some screen shots for you guys. Hopefully things stay the way they're running now.

I updated my T-mobile S7 and haven't noticed any difference in my battery drain. Android System still uses 20+%.
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
Did you clear cache? Also try turning off diagnostic reporting if you haven't already.
[Samsung Galaxy S7 Edge Questions and Answers] meblah741:
Thanks I will have to check it out!
[Samsung Galaxy S7 Edge Questions and Answers] laureanop:
OK guys cross referencing from my regular T-Mobile S7 ( had to return Edge because of SD card issues) Took the update this morning and as we all suspected, the issue was at OS/kernel level. Used the phone the whole day and Android System is dramatically improved! I guess they listened to all our complaints! Now keeping an eye on that cell stand by which seems a little high but on par with our Exynos brothers.

Yes!! Palm rejection seemsbmuch better and I'm FINALLY not accidentally pressing and selecting things with my swiping finger when scrollingbbecause of the sensitivity. . This was my biggest issue with this device and its all good now. 8m actually seeing higher benchmarks and better performance in some games also. I game a lot with this phone. But the performance in maps is still stanky. Hope that changes too soon. Awesome battery tho I'm noticing too. Good times. Thanks slamslug

My Sprint S7 battery life sucked from the get go. Today I've used it to read / send email and text. No youtube, no games, no music, nothing. I unplugged it at 7am and it is now 1:18pm and the battery is at 53%. My HTC One M8 had better battery life than this. Kinda regretting not waiting for the M10.
[Samsung Galaxy S7 Edge Questions and Answers] JasonJoel:
How do you know the M10 would be any better?? Lol

Plus without stating SOT those times you listed really don't mean anything. If the screen was on the whole time, that would be awesome battery life for instance.
[Samsung Galaxy S7 Edge Questions and Answers] Ghstudent:
Why? Because the phone has bugs on launch? If you don't want bugs then don't buy a phone at the very beginning of it's lifespan. Samsung has already realized that there is a problem and they are already pushing the fix to it (through carriers, mind you) within a month of the launch, that's pretty damn impressive if you ask me. And by the way, the m8 had a lot more issues than battery drain upon launch. Just saying.

Seems like Clean Master is killing you. I've never seen much use for it.
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
Looks like you did a recent system reboot. Try charging it fully and then do the screen shots over again once the battery hits 50%

That would give us a better idea. I'm the meantime though, get rid of that useless app called Clean Master. It's hurting more than helping.
[Samsung Galaxy S7 Edge Questions and Answers] Ghstudent:
1.Clean master doesn't shut down apps properly, which in turn makes the app reboot and go through the entire process it was trying to complete once loop multiple times. App killers have been reported over and over again to be counterproductive on Android, as they usually make you lose battery instead of helping them.

2. I never was under the impression that you were a child, however, you are acting like one and therefore I'm going to talk to you as such. Coming into a thread complaining about how your new toy (or phone in this case) doesn't work 100% like it was shown on the TV and complaining how you should have got a different one instead a mere few weeks after obtaining it is something that a child would do.

You can take my advice or disregard it, I'm not gonna lose sleep either way.
[Samsung Galaxy S7 Edge Questions and Answers] mcbutters:
People complain on this board and pretty much every other message board on the internet all the time. It's human nature to complain, but it doesn't mean that those that do, are acting like children.

After Tmobiles most recent update here is proof that Android System is no longer a drain on the battery. After this update I'm getting my best SOT yet. I'm on pace for 8 hours SOT and that's along with streaming a few hours of podcast over Bluetooth. Without the Bluetooth streaming I could probably hit 9+ hours.

[Samsung Galaxy S7 Edge Questions and Answers] jc83:
I was sitting in low to mid 20s prior to update and for the longest time getting 7+ SOT with heavy use. Now around 4-5 hours SOT but I am thinking an app I have is draining my battery.
[Samsung Galaxy S7 Edge Questions and Answers] mdewyer:
Updated yesterday, cleared cache yesterday, charged to 100% last night. Android System might be a little lower, but it's still the top for me.
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
That GSAM list is only of the apps. Look and see how much it's using in under the battery settings on the phone. It should be even a lower percentage.
[Samsung Galaxy S7 Edge Questions and Answers] mdewyer:
It's actually higher under Battery Settings for me :-/
[Samsung Galaxy S7 Edge Questions and Answers] km8j:
On the new build, I'm at ó hours off the charger, 1hr SOT, 40 minutes voice calls and 66% left. This is with aggressive package Disabler. Some people claims this makes it worse. Not sure on that but my battery life is not impressive even though the reporting seems better
[Samsung Galaxy S7 Edge Questions and Answers] emptydream:
It's normal, can you click into android system see how much mAh it uses. If you have long voice call and didn't use screen that much. The android system will still stay on the top. However, percentage doesn't tell you the whole story. You need look into how much mAh it actually using. If android system usage for battery falls under 500 mAh to 600 mAh I think that would considering very normal. At least that how much I got each day after update. Before update I will hit 1300 easily each day. Also you are 9 hour into battery with 70% battery left, you can easily use your phone for a day and half. I think that's pretty good battery life.
[Samsung Galaxy S7 Edge Questions and Answers] km8j:
What I'm not understanding is how people with the edge can get 9 hours SOT and those without the edge top out at 5-6. The battery on the edge is only 20% bigger
[Samsung Galaxy S7 Edge Questions and Answers] mdewyer:
Good to know. Right now it's at 181 mAh. And yeah, I'm not complaining about the overall battery life, just noting that Android System is still top of the usage list after the update. But understood that if I was using other things more, its share of the usage percentage would probably go down some. In my case with my "normal" usage the update doesn't seem to have changed much, but maybe I'm using the phone in a way that doesn't highlight the improvements.
[Samsung Galaxy S7 Edge Questions and Answers] emptydream:
Yeah basically, that's totally normal for 181 mAh. In the weekend if you use your phone more and reach 3 hour of screen on time. You will seenjoy screen on the top. That never happen before the update, no matter how hard you try to use it, the android system is always on the top.
