Does anyone know why gsam reports different SOT from stock usage? They both have the same off the charger time
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
I don't think the system reports SOT when you're just looking at the Android UI or scrolling around through system settings.
[Samsung Galaxy S7 Edge Questions and Answers] meyerweb:
They seem to be the same on mine, at least right now (1 hr 7 minutes on both). Do you have AOD on, and is GSAM higher? Maybe GSAM is counting AOD as screen on and the phone itself isn't.
[Samsung Galaxy S7 Edge Questions and Answers] km8j:
No aod. Gsam higher
[Samsung Galaxy S7 Edge Questions and Answers] martinezma99:
My GSAM shows SOT higher by about 5 seconds. That's close enough for me.

How do I get wifi to turn off while my phone is asleep?
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
Turn it off manually. ?
[Samsung Galaxy S7 Edge Questions and Answers] jgodfrey82:
I've just been leaving wifi off unless I need to stream or have a large download, otherwise I never come close to using my data so I get battery and use what I'm paying for. Win win

Why do GSAM and normal battery info differ so greatly? The relationship between YouTube and Android System is completely different...

My phone drains 40% battery within 8 hours while I'm sleeping. -
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
I think it's safe to say.... "Houston you have a problem"

Seriously though. You should not drop more than 5% over night. Last night my phone dropped 3% overnight.
[Samsung Galaxy S7 Edge Questions and Answers] WWEFANS:
wifi and data connection kill the battery, it lives much longer after I turn on the airplane mode.
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
Try doing a Factory reset. When you're setting the phone up make sure you opt out of all diagnostic reporting to Google and Samsung.

Also try setting it up as a new device rather than transferring another phone.
[Samsung Galaxy S7 Edge Questions and Answers] C0derbear:
Under WiFi "More" aka advanced settings you can configure WiFi to only be "on while charging" so that it turns off when the phone sleeps.

Assuming nothing else process-wise is holding it on.
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
What he's saying is that he already his this option checked.

It doesn't matter if you have your WiFi set to sleep while the phone is sleeping. GSAM will still report it as running.
[Samsung Galaxy S7 Edge Questions and Answers] mfish123:
I had the setting set for "while charging" for over a week and wifi stayed active all the time. About a day before I posted I switched it to "never" and am still getting the same result.

Is there a way or an app that I can use (I am not rooted) to try to figure out which process / app is keeping my wifi on 24/7 (even while the phone is in a deep sleep or doze)? Thanks.
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
It could just be the way GSAM is reporting it. The WiFi radio may stay activated in standby mode even though you have the WiFi set to sleep except while charging.

A quick way to tell if your WiFi is sleeping is to turn your display off for 5 minutes and then turn it back on. If you see a pop up towards the bottom center with the WiFi network then it is in fact sleeping properly.

Since the last update, yesterday, i have a big drain battery from android System.... and you?
[Samsung Galaxy S7 Edge Questions and Answers] cuezaireekaa:
Which update? PC8 or PD1
[Samsung Galaxy S7 Edge Questions and Answers] meyerweb:
I'm curious. Has anyone who got the T Mobile update that reduces the battery usage assigned to Android System and OS noticed any actual improvement in battery life? Or, as some speculated, is that battery usage just reported differently / elsewhere now?
[Samsung Galaxy S7 Edge Questions and Answers] ilan78:
PD1

[Samsung Galaxy S7 Edge Questions and Answers] mjs2011:
Wish this update would come out for AT&T already!
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
I noticed better battery life. Maybe another 1.5 hours on screen time.
[Samsung Galaxy S7 Edge Questions and Answers] hp79:
I'm on PB5 with Verizon model. After all updates I did a factory reset just in case since I had just bought this phone. None of the apps were restored. All ckean installed. I measured about 3% drop per hour overnight. (20% over 7 hours)

This is with the night clock enabled. It didn't make a noticable difference with or without.

I have BT and WiFi on with a LG G Watch connected all times.

No analytic data reporting and a few apps disabled.

I can get through a day but thats only because the battery is beefy. I hate the feeling that they might be letting this be a low priority just because the battery still lasts longer than an iphone.

It's ridiculous seeing this high drain even on idle.

edit: By the way, I'm at school right now, WiFi also seems to have problems. It shows it's connected, but I don't have internet access. It's 11:50AM and now (14 hours unplugged) I have 43% battery left. :(

Screen on time is 1:35 minutes so far.

Unplugged since 10PM last night. Looks like it'll only last 24 hours if I use it like this. Man, I hope they fix this crazy battery drain problem.

edit2:

By the time I got home I hd 5% left.

I uninstalled samsung push services update and now it's back to 2-3%/hr standby. I tried turning off BT and its now 1%/hr.
[Samsung Galaxy S7 Edge Questions and Answers] givmedew:
Does VoLTE matter in this equation? I wouldn't think it would... I'm going to try turning off cellular, connecting it to wifi and letting it sit for a work day with no use.

Verizon vs T-Mobile shouldn't matter anymore that is until I thought about the fact that your phone is connected to VoLTE and mine is not. That said... everyone with Sprint would be having batter issues if this was the culprit.

My HD Voice/VoLTE is off I can not enable on the account at this moment. It has something to do with another billing feature code/plan that is incompatible. Problem will be resolved NEXT billing cycle but I do NOT think it is the reason for the poor battery life.... My HD Voice/VoLTE was shut off on the iPhone as well and it had great battery life.

ALSO!

I installed that app... how do I verify if it is going into deep sleep?
[Samsung Galaxy S7 Edge Questions and Answers] bluemu:
I have the recent T-mobile update installed and unfortunately it didn't do much, if anything, for my battery situation. Android System is still draining my battery like crazy. I've tried pretty much every suggestion on these forums, including a factory reset and manually re-installing apps, all to no avail.
[Samsung Galaxy S7 Edge Questions and Answers] JLintheTL619:
Have you tried restricting background data for your apps through the app manager? Doing this has helped my phone go into deep sleep and doze more often

[Samsung Galaxy S7 Edge Questions and Answers] hp79:
I can confirm that in verizon version, samsung push service update (from playstore) caused a major battery drain. After going back to factory version I see 2%/hr drain. Bluetooth is still on 3rd place gulping battery
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
I have VoLTE enabled.

After you're phone has been running for about 10 hours, go into GSAM and you will see the "Keep Awake" section. Click on that and it will tell you how long your phone stayed awake with the display off, how long it went into deep sleep and how long it spent in Doze mode.

935F Edge here - I literally have Android System not even making the chart for battery drain.

Top 3

Screen 16%

Play services 16%

Cell Standby 16%

Android System isn't even on my list. Exynos international version is amazing. Two day battery life with my usage, vs having to charge every night with the stock AT&T Edge.
[Samsung Galaxy S7 Edge Questions and Answers] bluemu:
Wish I could say the same. Android System is currently 42% for me and has been above 40% ever since I have had the phone.
[Samsung Galaxy S7 Edge Questions and Answers] JLintheTL619:
Do you have greenify installed with aggressive doze activated? It'll put your phone in doze within minutes and thus reduces standby drain fairly well
[Samsung Galaxy S7 Edge Questions and Answers] bluemu:
Yes, I did have Greenify installed previously with aggresive doze. I know it does not make a lot of sense, but Greenify actually seemed to make the battery drain situation somewhat worse.
[Samsung Galaxy S7 Edge Questions and Answers] JLintheTL619:
Hmm I'm out of suggestions at this point. I guess the only thing to look forward to is the new update
[Samsung Galaxy S7 Edge Questions and Answers] bluemu:

Does anyone know whether if I were to root my phone, would I definitively be able to determine what specific process is causing my Android System app to consume so much battery power? I feel like this might be the only option I have left, but I don't want to go through the trouble of rooting and later unrooting my phone if I'm not 100% certain that I would be able to identify the root cause (at least in terms of the specific process causing this issue).
[Samsung Galaxy S7 Edge Questions and Answers] psufan5:
Are you on a carrier brand or international?
[Samsung Galaxy S7 Edge Questions and Answers] h.nocturna:

[Samsung Galaxy S7 Edge Questions and Answers] givmedew:
OK it was not deep sleeping or dozing. I wiped the phone and didn't download anything went to bed with 50% battery woke up with 48 so it's got to be an application or something like a setting... Maybe even something I disabled so I'm going to take it slow and keep track of everything.
[Samsung Galaxy S7 Edge Questions and Answers] samuel2706:
I had this problem for a while, not sure as to what stopped it in the end (maybe countless flashing), it just seemed to fade away, i didn't really look in to it. However i do now use greenify/amplify and i'm getting pretty decent battery life all round so maybe try that (if rooted with exposed)

Thank you for letting me know. Too bad.
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
Good. Yes take it slow. That's what most of us did. Don't disable anything until you have slowly installed every app you want to run with. After that you can slowly start disabling things.

Also did you disable the diagnostic reporting to Google and Samsung?
[Samsung Galaxy S7 Edge Questions and Answers] givmedew:
OK, what about this app greenify people are talking about?

No I didn't disable reporting

I am using Samsung Galaxy S7 Exynos 8890 Indian unit. I was very happy with the device when I got it, but from the time I have done the April update I have started getting a HUGE Android System battery drain :( I just did factory reset today morning & from the time my phone was setup with login details, I went to check the battery & already Android System had used 28mAh of my battery. Is our phone experiencing any issue? Should we return it back & get a new device?
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
I don't use it. Some people have used it with success and others say it hurt their battery more. I wouldn hold off on it now.

Definitely disable the diagnostic reporting. Also, turn off WiFi and Bluetooth scanning.
[Samsung Galaxy S7 Edge Questions and Answers] bluemu:
I have almost found a solution. I installed JuiceDefender beta, and as long it is enabled my battery drain drops dramatically. It's actually quite amazing how long my battery lasts when this works. The steep slope of my battery drain chart almost flatlines. The only problem is that the app does not stay enabled. It was fine today until I started using my navigation apps. Once I use one of these apps, it seems to be impossible to enable JuiceDefender until I restart my phone. I've tried both Google Maps and Waze, and both apps seem to stop JuiceDefender from working until I restart my phone. I suppose it is possible that something else is causing JuiceDefender to disable that happens to run simultaneously with my nav apps? I will have to test out for a few days. Does anyone happen to know how to keep JuiceDefender enabled regardless of what other apps are running? If I could figure this out, my battery issue would be solved. The second JuiceDefender disables, my battery drain jumps again. In any event, this finding seems to clarify for me that I'm probably dealing with a software issue rather than a hardware issue. Obviously, it would be ideal if I could figure out what JuiceDefender is actually doing and just change whatever settings it is affecting, but I have no idea how to figure this out. Please let me know if anyone has any suggestions.
[Samsung Galaxy S7 Edge Questions and Answers] dhaugru:
How do you disable the diagnostic reporting? I am using the international "F" version. Thanks!
[Samsung Galaxy S7 Edge Questions and Answers] Juuls:
Test the stable version to see if it's a bug which you should report to JuiceDefender's developers. As to the functions of the app, I think this depends on what profile you set, I remember when I used it on my GS2 there where several preset configurations (from light saving till max saving). I also remember the app was pretty wel documented in the app itself and on the interwebs.

Can anybody else confirm that juice defender works?
[Samsung Galaxy S7 Edge Questions and Answers] bluemu:
I tested the stable version, but it suffers from the same issue. Unfortunately, this app has not been updated since 2012 and no longer appears to be supported by the developer. The support site has been taken down. It's a shame. It is the only thing that has worked for me.

I wanted to say that the first week I had the S7E I had AWESOME battery life compared to my LG G4. Now, I get the same battery life. I even reset it to factory and installed just the minimum apps (less than I had the first week, TBH) and I'm getting weaker battery life :( ... This isn't promising.

Found the solution to my play services problems. Disable background data for the Google app. Settings - - > Data usage - - > Background Data. Toggle google to the off setting. However android system is still high but i'm getting great battery regardless so I can't complain too much.
[Samsung Galaxy S7 Edge Questions and Answers] Naemion:
I'm on Verizon and can't seem to find the setting to limit background data per app. Just a system wide limit.
[Samsung Galaxy S7 Edge Questions and Answers] bluemu:
On the Data Usage window where you can restrict background data for all apps using the upper right hand menu, scroll down to the Google App. Tap on the app and you should see a "Restrict background data" option.

This is just terrible for a 3600mah battery.

I still have my iphone 6S plus sitting here and I have half a mind to fire it back up until this battery mess gets sorted out.

Android is so annoying with this stuff? Why exactly did Google take away the ability to get detailed battery stats without root a few years ago. Makes zero sense whatsoever. Until we have root and we can see exactly what process is going crazy, threads like this are just random speculation...

Since I was not able to get JuiceDefender to stay enabled, I've been testing out some other apps and LeanDroid is making a huge difference in terms of reducing battery drain while my screen is turned off. However, I'm still getting relatively high drain while my screen is on.

the att update I got this morning fixed my Android system drain immediately, before it was average 35% every single day and now it's sitting in the teens, I didn't change anything except the update
[Samsung Galaxy S7 Edge Questions and Answers] Cst79:
On my S7 Edge (Exynos) the Android System was around 3% percentage. Battery life was great (up to and including the APC8 update), until the APD1 update which bumped the Android System drain to 15-17% and now battery life is much worse. Now it seems to be on par with the SD820, which is bad. I just did a factory reset to see if something improves. If not, I will downgrade to APC8 and ignore any other updates until I make sure that Samsung got their act together...
[Samsung Galaxy S7 Edge Questions and Answers] johanbiff:
here are the pics of the exynos model:

16% left. 5.5h SOT over 2.5days..should easy get another hour SOT with the 16% left.

I havent seen any SD820`s going for over 24H with high SOT.
[Samsung Galaxy S7 Edge Questions and Answers] dodgeboy:
I saw those posted as well, and they are really impressive. I definitely still think there's an issue with the standby draw on the SD variant of this phone. The awake/screen-on time is respectable. But the standby is consistently pretty underwhelming. In fact, when I look at the charts on my phone, it's usually not very obvious when I was using the phone and when it was asleep. Other phones I've had showed steep drop offs when I was using the phone (similar to the graph you posted). This one shows a slight dropoff, and sometimes it's not even noticeable. It's almost like the phone draws the same amount of power whether it's awake or asleep. If this thing didn't have a 3600mAh battery in it, I bet people would be struggling to get 12 hours out of it.

I've had a few times where my phone seems to idle nicely, and it will maintain its battery over 2-3 hours (same percentage). However, usually I lose a minimum of 2% an hour in standby with this phone. That doesn't seem excessive until I think about other phones I've had that were pre-marshmallow, with much smaller batteries, that had far less of a standby draw than that.
[Samsung Galaxy S7 Edge Questions and Answers] Xileforce:
I'm not seeing this at all on my device. Here's my sot at 72% after 12h on batt. I took that last night before putting it on the charger otherwise I'd take one of the graph too. It barely used anything with screen off.

More os custimization by OEM, more battery for Android system I think
[Samsung Galaxy S7 Edge Questions and Answers] msage:
Charged to 100 before bed and left off the charger overnight and this is the result. Seems excessive to me? Those were the only 3 on the list which is curious to me because I left the Always On Display feature on to get an idea of its real drain on the battery but Screen doesn't even show in the stats. I'm wondering if for some reason AOD is actually reporting under Android System. I also forgot to turn off location so maybe that reports under Android System as well?

Overall I haven't been experiencing the stellar battery life that a lot of other folks have. Day 5 for me now with a Tmobile SD820. My best SOT is 4 hrs with 12.5hrs on battery, 3% left on battery and 29% Android System, 15% Screen. Not impressed with that at all.
[Samsung Galaxy S7 Edge Questions and Answers] dodgeboy:
I have noticed that the first 10% (from 100% to 90%) goes really quickly on this phone... Some phones artificially stay at 100% for a long time, to make you think the battery is going to last forever. This phone seems to be the opposite of that, and drops off of 100% almost immediately after pulling it off the charger. I find that the 89-70% range seems to take the longest to get through. It definitely doesn't seem like a linear gauge of battery life.
