I'm not getting my s7 till Friday, but I've been tinkering with my wife's SD S7E a lot. Can the people with both Exynos and SD post the following numbers right before you charge your phone's at the end of the day please??:

Under Android System battery stats : total CPU use , total background CPU, time held awake and GPS.

This will greatly help determine if the issue is with the reporting itself or with the actual use coming from those

The more I use the phone the more I realize that this isn't an issue. Even with Android being the top battery user I am still getting a good full day with 6 hours of screen on time. I am quite happy with the battery performance regardless of what the stats say. :) I do still wonder what's possible if Android really is pulling as much battery as it says it is.

By the way.... I wonder if anyone has tried to binge watch a full season of Game of Thrones like they said was possible in the GS7 announcement.
[Samsung Galaxy S7 Edge Questions and Answers] dodgeboy:
The issue isn't the amount of active time you can get from the phone/battery... the standby time seems to be the issue. With as much SOT as is possible with this setup, this thing should easily be able to standby for 2 days. There's no way I could do that with my phone. I'd get *maybe* 36 hours out of it, if I didn't use it at all. I get 24 hours out of it with 5hrs of SOT. That just doesn't seem right.

While the battery is good enough to get just about any of us through a day, I think it's just because of how huge the battery is. I think there's still an issue going on here, with sleep/doze/standby mode.
[Samsung Galaxy S7 Edge Questions and Answers] greyhulk:
I turned off Google Now and disconnected my Asus Zenwatch 2, thinking that was the cause of this. No dice. I also turned off location history and Android Device Manager. I'm still getting this drain. What happened to doze? On other phones I have with Marshmallow (Moto X Pure, Nexus 6P, etc) they do not have this idle drain.

Maybe the batter life is still good, especially if you're using it regularly, but compared to an iPhone, this steady idle drain is concerning to me.

[Samsung Galaxy S7 Edge Questions and Answers] skinnytoo2:
I came from the Huawei Mate 8. That device has a 4000mAh battery. My S7e has 3600mAh. If you do the math the Mate 8 battery is 11% bigger than the S7e. After a full day on the Mate 8 I would plug in to charge overnight and the battery was consistently at 46%-50%. My S7e after the same usage all day has been around 5%. There is a substantial difference, no where near the 11% difference in battery size. Thus, something is definitely wrong with the S7e and its substandard battery performance.

I'm tempted to do a factory reset. That's what I did with my S6. Not sure it really helped so much with performance. It definitely decreased Android System and OS usage.

[Samsung Galaxy S7 Edge Questions and Answers] C0derbear:
In theory as long as you have the correct image and ODIN you can downgrade a non-rooted device without issues. There are caveats though.

- some boot loader counters when incremented will NOT allow downgrade

- you will lose potentially important security fixes

- ?

To me the security fixes are the killer though. In today's world of the Antagonistic Internet you simply can not trust any other system to not have been compromised. Knowingly ham-stringing your device by reinstating known vulnerabilities is a non-starter for me. Everyone gets to make their own choices though.

For me, after 1 day (so very inconclusive) Android System went down about half of what it was but Android OS went up significantly.

Overall battery endurance was fine though (~35% consumed during a work-day), so I don't think this is conclusive by any definition. Ask me again in a week. ;^)
[Samsung Galaxy S7 Edge Questions and Answers] mjs2011:
Thanks. For some reason I thought that even if I did that, Google Music wouldn't connect to the contents in the SD card after a factory reset.

crazed_z06, how are you able to drill down to see what specific processes are draining your battery? Are you rooted? The most I seem to be able to see is the app level. I would like to know what specific processes are causing the most problems for me.
[Samsung Galaxy S7 Edge Questions and Answers] crazed_z06:
i use this app called system panel.. It doesnt need root..

https://play.google.com/store/apps/details?id=nextapp.systempanel.r1

It has a monitoring function you can turn on and it keeps track of all the process CPU usage. You it can shows graphs of CPU freq, discharge rate, etc.

The other app I was using is called OS Monitor.. I found it yesterday just looking for anything that might shed light on what the heck is running. It seems to show what I'm seeing in the system panel app. system_server just constantly using battery.. specifically when the phone is in use.

[Samsung Galaxy S7 Edge Questions and Answers] bluemu:
Thanks. Using the OS Monitor app I'm noticing high CPU usage by the system_server and system processes.

I think I'll let the dust settle to see how it goes.

Yes, the battery may still be good, it seems like it was nearly twice as good before - I was really getting 2 days with 6hrs screen on.

I'm currently on 10% after 3.75hrs screen on and just over 24hrs since last charge.

Yes, it's too early to tell - but that's all almost half!!!!

I'd like to throw my voice into this discussion. I had two S7Es, one black and one white, both from the same carrier. On the black model I was getting SUPERB battery life and on the white model I'm getting horrible battery life. On the black model, on a typical day I'd get home with 60% battery life, and on this white model, which is the one I am keeping, battery life is horrible. I get home with maybe 15-20%. I see very high amounts of Android System. I download the application and I see that Android System is very high, with a process called "system_server" ... Is there any way to diagnose this a little better and see what exactly is eating away at my battery? I've even taken more actions to save battery on this model by using a black theme, uninstalling completely applications, etc. This is concerning!

[Samsung Galaxy S7 Edge Questions and Answers] h3x3d:
Non-scientific, but with only 53mins on screen time following a full charge today, my screen is finally showing as the largest drain after just over 6hrs.

As I say, this isn't scientific but is looking a bit better than yesterday.

I have location, AOD, WiFi, mobile data and full syncing enabled. I'm holding off on going down the battery saving rabbit hole for as long as possible.
[Samsung Galaxy S7 Edge Questions and Answers] bluemu:
My wife and I both have gold models from T-mobile. She has always gotten amazing battery life similar to what you describe with your black model. I've always had terrible battery life. I can't even get through a day with any battery power left with normal use. This is with using an app that seems to pretty much shut down whatever is causing the problem when my screen is off (LeanDroid), since my battery drain flattens out now when my screen is turned off. The problem is that once I turn the screen back on, "system_server" jumps back into high gear using between 15 and 20% of my CPU. The "system" process also drains between 6 and 12% of my CPU. Would be great to no more about what is causing this and if this is actually attributable to a hardware defect. I didn't think hardware was the explanation since I returned my first gold phone and the second gold phone also had the same issue, but your post makes me wonder if perhaps I just got unlucky and received two duds.

Maybe it's time to separate problems like battery drain in own threads for Exynos and Snapdragon, it's not always easy for who is reading to understand about which S7E model an issue is occurring.

[Samsung Galaxy S7 Edge Questions and Answers] optimummind:
What pisses me off is how initially the battery was really good then after subsequent updates, it's getting worse. Samsung needs to prioritize battery life again, especially the standby drain.

Ok, so I compared the list of Android System services from the update APC8 (which drains around 3% of battery on my phone) with the list of Android System services from the APD1 update (which drains 15%+ of battery on my phone).

There is only one added service in the high-drain update: OM Customize (com.sec.android.omc).

Can anyone disable this service (with Package Disabler Pro maybe ?) and see if it improves battery drain ? (I don't have this service on my phone since I downgraded to APC8).
[Samsung Galaxy S7 Edge Questions and Answers] SEVENEDGE:
Just a theory. As samsung or the carrier update the phones, they phones lose battery life and/or lag as time goes on ie. the samsung GS5. So when the new phone arrives, people will be influenced to go to the new phone. The GS7 Edge is a phone that can probably be a keeper for years, but there is no profit in that...

This is similar to my battery life that I've had since day one. According to GSAM I get a little over 20 hours with 4 hours 45 minutes of SOT. This is with AOD on, Bluetooth always on for Android Wear, some apps disabled through TouchWiz and I do a fair amount of gaming (Clash of Clans, Clash Royale, Game of War).

Since the latest AT&T update, screen has passed Android System as the highest drainer.

Did you factory reset your phone after that update Verizon sent to? I finally did today, cause I causes an error by disabling packages, and it might have helped
[Samsung Galaxy S7 Edge Questions and Answers] hp79:
Are you asking about my Verizon S7 Edge? I did a factory reset right after I got the latest update about a month ago, which was when I bought this phone. It's still on PB5 and battery life sucks on standby with BT on. Even with BT off and lot of stuff off, Android OS and System comes up as highest consumers.

I do get about 5 hour SOT and 24 hour combined standby if I keep my BT off so it'll last throughout a day, but using up unnecessary power will wear out the battery more quicker and I intend to keep my phone for at least 24 months.

Maybe you should try a factory reset if you haven't already.

I know, it's annoying and a pain in the ass but it's kind of the last cure if there is any for these things. I do factory resets (or clean installs) on my Macbook and Windows desktop with major version changes or when I feel like I have the energy to do so.

Odd my battery system stats says android system is 27 percent, and gsam says 5 hmm
[Samsung Galaxy S7 Edge Questions and Answers] bailyc:
I asked a couple weeks ago if it was safe to disable Knox, and most advised me not to. Have you run into any issues with yours disabled?

I have been able to get my battery drain down to about 3.5-4% per hour (on standby with screen off) by disabling most of your recommendations, except I haven't touched Knox.

Interestingly (Verizon user here) I have found in the last couple days that if I never enable wifi, the percent drain is much lower, like between 1.5-2.5%/hr. It lasts me much longer. I say this with complete surprise, because it has always been my impression that Wifi is a battery saver over LTE.

I am in a major urban area with tons of skyscrapers, and GSAM confirms that my cell signal is not awesome throughout the day. Sometimes it's around 70% but it usually hovers around 50% and can be as low as 20. So, not great, which I'm sure accounts for at least some of my poor battery life. So the fact that the wifi is so buggy that it's better for me when completely off is kind of a letdown.
