[Samsung Galaxy S7 Edge Questions and Answers] Carterman32:
Here's proof that Samsung isn't going to do anything. As I mentioned, I've spoken to them multiple times about the issue, and I just did another chat, where I was told, yet again, that nobody has ever reported this before. They have some sort of communication problem. See below.

Sahu S: Hi, thank you for reaching out to Samsung Technical Support. How may I assist you?

Sahu S: As you are chatting from a mobile device, there is a possibility of chat getting disconnected due to network disruption with WiFi or Mobile Data/Signals. In case we get disconnected, please use the Chat ID: 4306467334 to connect with us.

COREY: I have called and talked on this chat multiple times and keep getting different answers. There is a problem with ALL US based Galaxy 7 and 7e phones with the Snapdragon processor. Android system drains the battery and is always listed as the top battery drainer.

COREY: Even in safe mode

Sahu S: It must be inconvenience as you are facing issue with battery draining on S7. I will be glad to help you.

COREY: This applies to every single US phone, not just mine. There are long threads about this on xda, but every time I talk to someone at Samsung, they either say Samsung doesn't release patches, or that they've never heard of this issue

COREY: You won't be able to help. The only fix is a software patch at the kernel level. As I said, this affects every single US version of the phone.

Sahu S: I do understand your concern.

Sahu S: Are you facing the issue in safe mode also?

COREY: I already said yes

COREY: Every single US phone has this issue. The enoxys version does not

COREY: You guys need to address this and stop asking people to put their phone in safe mode, do a full wipe, wipe cache. It is 100% related to the kernel.

Sahu S: Thank you for bringing the information to US. I will send your concern about the battery draining issue to our concern team.

COREY: I've already done this. And every time I chat, I'm told nobody else has reported it. But every single US customer is experiencing it. Can I send you a link from a forum that your engineers can look at that shows the issue?

Sahu S: Sure. I will appreciate it.

COREY: http://xdaforums.com/s7-edge/help/how-experiencing-android-battery-drain-t3327730

Sahu S: Thank you.

COREY: That's an entire thread about "android system" dominating battery drain on US based snapdragon processor phones. Again, it affects every single customer, not just a small subset. I don't understand why I've called and chatted multiple times, but been told nobody has reported this.

COREY: Can you confirm that this issue has previously been reported in your system?

Sahu S: Please provide me with the following details so that I can raise a ticket which will be checked by our dedicated team

Sahu S: 1. First name:

Sahu S: 2. Last name;

Sahu S: 3. Email- Id:

Sahu S: 4. Contact number:

Sahu S: As of now we have not received any complaint about the battery draining issue.

when I've had this conversation multiple times, as have others in that forum?

What's the number 1 drain under your battery?

Lol. What do you think. I'm on a US version. Android System of course.

I kind of have my Android System under control but that's not the point. With two hours and forty minutes sot over 11 hours there's NO REASON for Android System to double my screen consumption!!

( Hopefully Samsung starts reading this stuff)
[Samsung Galaxy S7 Edge Questions and Answers] Picolini:
While I know battery issues suck, and manufacture "support" is even worse, it's not every snapdragon. I'm getting about 45-50 hour battery life with 5-6 hour SOT with a VZW GS7E.

Android system is almost always at the top of the battery usage page, screen is surprisingly 2-4 spots down. Ultimately, the way I'm reading this is that the components and SW are working so efficiently that it's just running the core OS that takes most of the power (along with some data/cell services that are under the Android System group).

Obviously it'd be a problem, but only if my battery life were poor. Which it isn't. I'm not saying that any of you aren't getting poor battery life, but mainly that your expectations of what SHOULD be the top battery consumer is wrong with what will be in this device. Also that you can't claim all Snapdragons have this problem as myself and many others do not have the issue.

On a side note, I worked tech for VZW for years. The only true fix, outside of an update with specific changes to resolve this issue, is to get a replacement. The odds of any troubleshooting is slim, and you'll just be left with constant reps dropping the ball (Samsung, Google, or cell carrier). You're best bet is to go through as much troubleshooting (ultimately will end with a factory reset and reproducing the issue) then they'll have to offer a replacement. Not sure what Samsung does, VZW will send you a brand new one (or swap out in store so no out of pocket cost until returned phone gets to their warehouse) within 14 days of purchase. 15 days or more and you're getting a refurbished phone (somebody else's ****ty battery hog). I'd go to Samsung if beyond those 14 days and push for a new replacement since it's within OEM warranty. I couldn't imagine sending it in for servicing to do any good.

Eager to wait

Waiting to use but really u are facing such kind of issue . One of my friend using it and according to him he is enjoying best experience with it . I personally did the hands on but did not find this issue . overall performance is excellent :good::good::good::good:
[Samsung Galaxy S7 Edge Questions and Answers] Carterman32:
I don't think returning the phone to verizon or Samsung will fix the issue. I seriously doubt that snapdragon is just so efficient, because 1) European models are not showing this issue, and I strongly doubt the Exonys is that low in efficiency 2) the Galaxy Note 5 got the same update, but was previously on Lollipop. When it got the update, it also started having the same issue with Android system dominating battery drain.

Yes, some people are getting good battery life, which strongly depends on how you use the phone. But the truth is, without this android system issue, issue, you'd be getting significant BETTER battery life.

The inability of either Verizon or Samsung to acknowledge and fix the problem is frustrating. I don't understand either of them. Samsung and Verizon both serve to lose here when thousands of people return their new phone.

Just contacted local samsung support in HK. Same story... "we have not received any complaints yet, but we'll inform the relevant parties"

---------- Post added at 05:56 AM ---------- Previous post was at 05:46 AM ----------

By the way, whether that is true or not, I advise everyone to contact their local support to report this issue.
[Samsung Galaxy S7 Edge Questions and Answers] km8j:
Report the issue to Twitter. Also to those of you saying Android system should be at the top, it isn't bad reasoning except that our battery life sucks and the CPU and keep awake is crazy
[Samsung Galaxy S7 Edge Questions and Answers] DeeZee3000:
I am attaching a photo of an S8 battery consumption screen... Now the screen itself did use more than Android System on this one, but these are demo devices with screens ON the whole day (and the burn in to prove it).

But the Android System battery consumption is at 37%, which is practically the same as the worst case on my device (34%).

Although you do have to consider that due to how these devices are being charged, the sum of all percentages can come to more than 100.

That's due to the new way Android shows battery consumption. The numbers only reset once you charge above 90%.

The other side of this new way of showing consumption means, that if you are not at 1% battery when you look at this screen, you don't see the total battery consumption - all the percentages listed only add up to what is missing from 100%...

EDIT: The only way to get the "Android System" to back off is to switch off any kind of internet connectivity.

The apps and services can smell the connection, and switch into high gear, further supporting my fears...

The only way to fix this would be to root the device, and start freezing the individual components off one by one, until the crazy goes away.

But if this really is some kind of virus, it would probably just keep moving around. Perhaps a complete wipe is required, followed by flashing a clean version of the system.
[Samsung Galaxy S7 Edge Questions and Answers] shah22:
Which firewall were you using?
[Samsung Galaxy S7 Edge Questions and Answers] DeeZee3000:
I am using the local VPN based no-root firewall called NetGuard.

I have all the pro features, but the free version on Play Store also logs all access attempts. In addition, the GitHub version can filter out ads (except inside the YT app).

Practically all the essential features are free.

So even if you don't think you need a firewall, you could just set it up to let through all the traffic, but still have it log access attempts.

Seeing those logs can be very informative. Or worrying.

EDIT: You have to enable "Manage System Apps" in Advanced Options in order to capture and control "Android System" access attempts.
[Samsung Galaxy S7 Edge Questions and Answers] shah22:
Ok i did some tests, and i think that your suspicious android OS results are due to some malicious app or some cookies , because for me android OS isn't sending data to some blogspots or suspicious websites, you should do a hard reset or try clearing your browser data and uninstall useless apps, here's mine ss. I have also disabled all bloatware apps which i don't use.
[Samsung Galaxy S7 Edge Questions and Answers] DeeZee3000:
Thank you for sharing your results. That access log looks very clean compared to mine.

But that leaves me with one question. What is your Android System battery usage? (And due to the new way of reporting, please add how much battery was left when you looked at the usage percentage)

Yes, it seems something is seriously wrong with my phone.

But whatever it is, it persisted through three factory resets (with clear cache / dalvik / everything) already!

I'm going to have to wipe everything completely and install a clean system, after rooting.

The weird thing is, I have no idea how this could have gotten on my phone. I feel like it was in there from the start. The service provider modifies the OS and adds bloatware, but I always remove or disable it.

But additionally, I feel like our service provider also uses a severe forced obsolescence approach. Because I recently installed an official system update, which comes through them. And after the update I checked the patch level, and they didn't even get it to where the KRACK vulnerability would have been patched...

But they did manage to make my phone feel more crappy!

Suddenly it's hanging while scrolling, I mean it's only milliseconds, but when it was smooth before, you notice...

This is very bizzare.

And of course no help can be expected from them or Samsung or the official repair shop... When talking to them, we quickly get to the point, where I realize the person on the other end is clueless, and they even deny that such a thing as an Android virus exists...

So, yeah, I have no choice but to root and shred every last bit of data on the phone, even if it voids my warranty.

If you would be so kind, could you keep logging for a few more days, and then do a scroll capture, so I can show them the difference between our two logs?

Thanks!

EDIT: Also, how many apps are under the Android System UID in your case? I posted a scroll capture of mine (82 of them unless I add Gear VR), is there anything there, that's missing in yours?
[Samsung Galaxy S7 Edge Questions and Answers] shah22:
Hey bro, first of all you seriously don't need to do any shred or void warranty, simply reflash a samsung rom without carrier bloatware according to your region through odin, then after this, you shouldn't have any issues.

And no, I dont have any more apps in android system uid then the ones listed in ss, but the included packages are same, my android system battery usage was 1% less than my sceen usage, yes it was still high, but maybe its android 7.0 way of doing things, i counted the battery usage from 100% phone to 4% , at 4% battery left, android os had 16% and display 17%. I will keep logging and send you more logs, but first you need to reflash stock according to your region using odin. Or you can tell me your model no. and region.

Edit ; i have all bloatware disabled, also gear VR disabled too, i have only location on permanently, and a little bluetooth/wifi , and AOD screen on , i get 4 to 5 hours SOT, with 14 to 18 hours standby.
[Samsung Galaxy S7 Edge Questions and Answers] DeeZee3000:
Well, if I start flashing ROMs, I would kinda want certain functions limited to rooted phones as well. I want to automate certain functions. (Also, at the moment I can't use a VPN, because the Android VPN service is occupied by my firewall. With root, there are other firewalls, that don't require VPN, so you can combine the two.)

Additionally, even if I manage to make my Android System stop "spying on me" (or whatever it's doing), I still also want to make it stop wasting my battery. The battery capacity has already been eroded down to 3100mAh if not lower.

And with root it would be easier to find out which of the 82 services are causing the drain, and then block them, if I don't need them.

And I hope it's possible because an S6 manages to do all the same things without wasting the battery.

As it is, I sometimes have to charge twice a day, and if Android System is wasting a third, that means my phone could last twice as long without it.

And from what you said, your Android System is also a major drainer, despite not contacting weird sites....

But I didn't know I could flash without rooting first. I thought you had to root, flash and then unroot, while hoping you didn't trigger the Knox counter...

In any case, the only stock ROMs I saw were from US service providers. And I would rather find a custom one (Lineage is an option, now that Cyanogen is no longer developed). On my S3 I had to install Cyanogen mod, cos the official updates slowed my phone to the point where it would take 7 seconds to open the camera!

BTW, could you perhaps check your SCPM Client Access Attempts? It doesn't fall under the Android System UID, but in my case, it's also acting weird. Although less so.

EDIT: My model number is SM-G935F

Also reported as "hero2lte"

As for region, I'm in the EU, particularly, Slovenia. I don't think that will be of much help...
[Samsung Galaxy S7 Edge Questions and Answers] shah22:
No bro, you don't need to root before flashing ANY ROM, you simply flash twrp, then install your rom through it. But, i would suggest installing stock rom through odin, and then check the battery drain. I will give you the link for latest slovenia firmware, simply put your phone in download mode and flash the firmware. Also hard reset your phone before and after flashing and also do a cache wipe.

Edit : here's the link : http://fws02.updato.com/GALAXYS7EDGE/SM-G935F/BGL/SM-G935F_1_20171218105440_m5kwyd309u_fac.zip

I hope mods don't ban due to posting other sites links.
[Samsung Galaxy S7 Edge Questions and Answers] DeeZee3000:
Wow, thanks for the info and the link!

I will definitely try that, just to see, what happens with battery drain, and to compare the Access Attempt logs...

If Android System battery usage should magically become reasonable, I might just stick with that setup.

But if it doesn't behave, I can still root it and start disabling Android System services (until I cause a bootloop again :angel: )...

Anyway, thanks again!

EDIT: I just installed Virus total, which allows you to send APKs to them, to scan in 50 different antivirus programs.

And I noticed that it was possible to analyze System apps, and that most of them were not yet analyzed, so I uploaded all of them.

And the results are suspicious.

Now most only get noticed by 1-3 of the 50 AV programs, but the names of the detected issues are scary sometimes, considering the behavior i have been witnessing.

I will have to go through all of them, and then compare to the apps from a clean flash....

EDIT2: I searched through that page and did not see my exact model, but the download file you provided, does have my model name in the file name.

However, they have three service providers. Mine is Telekom (used to be called Mobitel).

Which one did you pick?
[Samsung Galaxy S7 Edge Questions and Answers] shah22:
You have unlocked phone or locked? If carrier locked you will need to install your carrier's firmware, the firmware i provided was carrier free for your country, if you have network lock you MUST flash your carrier firmware, here's mobitel firmware link : http://fws02.updato.com/GALAXYS7EDGE/SM-G935F/MOT/SM-G935F_1_20171023190740_53aq550z3f_fac.zip

Pls let us be on the battery drain topic, if you require any flashing assistance pm me. Good day !
[Samsung Galaxy S7 Edge Questions and Answers] DeeZee3000:
Thank you once more! I believe they forbade network locks in my country. But I can call and ask, or just stick another SIM in, and see what happens.

I would like to try all three options, to see how differently they behave...

I'm not sure I understand you correctly. Are you asking me not to post my results?

In any case, you've given me enough info that I can do the rest myself. (I had no idea stock ROMs from my country were available online)

So thanks again!
[Samsung Galaxy S7 Edge Questions and Answers] shah22:
Its ok you can post your battery drain results ofcourse, i was just saying not to move topic to flashing roms etc, hope you understand. :)

Edit: My scpm client had not made any connection

I've had mine 2 weeks and I was using 2 x batteries every day from 100% to shut down. Each battery lasting 6/7 hours. All apps disabled and app killer and Battery monitor was installed, still no good. Also experiencing very hot screen at periods throughout the day. Yesterday I downloaded " Juicedefender " from play store and my phone is currently sitting at 27% and has been in use now for the last 15 hours. A dramatic improvement with one app. Very happy now. Highly recommended.

Why worry about it if your getting 6 hours sot? The sd820 isnt as efficient as the 8890 so you guys should chill
[Samsung Galaxy S7 Edge Questions and Answers] dodgeboy:
It's been said probably 20x in this thread that the issue is not when the device is on (screen on time). The issue is that the device doesn't idle properly, so the standby time is dramatically reduced.
[Samsung Galaxy S7 Edge Questions and Answers] Ausboy 2011:
Oh well most devices have quirks at launch sit tight and wait it out
[Samsung Galaxy S7 Edge Questions and Answers] greyhulk:
Supposedly, Qualcomm developed the Snapdragon 820 in partnership with Samsung, so I would think it would be similar. Here's a screenshot from my Mate 8. As you can see, Android System is high. I have it set up the same way as my Samsung Galaxy S7 Edge, but have disabled doze on the Mate 8. Seems like this is more than just a Samsung problem.

[Samsung Galaxy S7 Edge Questions and Answers] LuigiBull23:
Yes, Android System is at the top of the usage screen but I'm getting 7hrs screen time over a 2 day period on battery. That's certainly not "dramatically reduced". I don't understand what all the fuss is about either. I think some people are just expecting a little too much out of the phone. Just my take.
[Samsung Galaxy S7 Edge Questions and Answers] Ausboy 2011:
Im not expecting to much lol ;)

[Samsung Galaxy S7 Edge Questions and Answers] km8j:
You are in the minority.
[Samsung Galaxy S7 Edge Questions and Answers] greyhulk:
Screen on time is fine. Better than most smartphones, in fact. The issue is idle drain. The phone will drain 2-3%/hr minimum, regardless of whether or not it's being used, 5-6% if it's being used moderately. So, if you unplug your phone from the charger and proceed to use it nonstop for 6 hours straight, I'm sure the battery life seems awesome. For those of us who have to do things like work, work out, etc. and only use our phones sporadically throughout the day, the battery life is a little disconcerting. I just tested it against my Huawei Mate 8 for an entire day. My Mate currently has doze disabled and the standby drain was much less. So clearly there's an issue here, at least for the Snapdragon version.
[Samsung Galaxy S7 Edge Questions and Answers] LuigiBull23:
Again, not on my end. I suppose you missed the part where I said I've already achieved 7hrs screen time over the course of 2 days on battery? So yes, I do use the phone sporadically. Whoever uses a phone nonstop all the time honestly has no life..

Anyways, here are my results once again. I'm not denying the fact that many people are having these high battery drain issues but my point behind my previous posts is that not EVERYONE is affected by it. I'm not sure why. Hell, I'm not even sure how in the world the guy above achieved 10hrs screen time (even under heavy usage?) but some have been fortunate enough to obtain devices with excellent battery life.
[Samsung Galaxy S7 Edge Questions and Answers] greyhulk:
I'm super glad you're magically not affected, but you're the exception to the rule. If you read through the thread here, a majority of the people participating are experiencing it. Continually reiterating "I don't see what the problem is. Mine is fine" doesn't help anyone. The people who are affected are comparing notes and trying to determine the cause.
[Samsung Galaxy S7 Edge Questions and Answers] LuigiBull23:
It's not "magic". Some of us just simply aren't affected by it and that is a FACT. I'm no exception to this "rule". Check out the link I posted above. That's just one thread showing what the device is capable of. The results speak for themselves. Enough said.

Sorry some are affected by this android system battery drain.
