Want 15 hours of screen time ? Download a video, put the phone in airplane mode, play the video in a loop at minimum brightness and you will get 15 hours SOT.

But is this the point ? Some people just want to brag about their results, but they are not real-world use results.

I've got 60% Android System usage right now, but sitting at 96% battery after 2h3m after I forced closed the VR service because I noticed it said it consumed 30% of the last fully charged battery.

my Verizon S7 (flat) must be defective or something. over 30% drain in 9 hours. I never turned on my phone, no background apps.

Here are my stats with vzw s7 edge. I disabled most if not all the vzw bloatware and still no luck. It was running fine the first 3 days then all of a sudden crappy sot performance. The screen is high now because I was reading this thread. Otherwise the screen is number 3 or 4 after android os.

Completely wiped cache and installed the os all over again fresh with no luck.

Hi all,

Here are my stats for comparisons - Exynos 8890 (Vodafone NL), Cheers

Check your app. Android system itself usually doesn't consume too much battery. However the system request like wakeup, locations or whatnot called by apps will be counted in system.
[Samsung Galaxy S7 Edge Questions and Answers] GeneralGiap:
So after talking to a Sammy rep and putting my phone into safe mode yesterday, it definitely got better power performance, but from what I understand, safe mode basically disables everything, including all apps. I couldnt text anyone but I did receive the texts, just couldnt respond. I did browse the web and use the phone for games and minimal FB.

In safe mode, i made it to bed with 40% of battery remaining (was at 79% when i turned on safe mode at 1pm PST). I left it off the charger to see how much battery drained during the night (remember the phone is still in safe mode). It was at 20% when i woke up. This also includes me leaving the phone face down so AOD was off...Not sure if this is good. 20% drain overnight (9pm to 730am)...its about 2% drain every hour. Battery usage says 1 day and 11hours with little more than 2 hours of SoT.

Thoughts anyone? I've read others have factory reset and turned off all bloatware to little or no affect on the battery so I do not know if i want to go down that hole...

Sprint Network (usually 4-5 bars), s7 edge, SD 820.
[Samsung Galaxy S7 Edge Questions and Answers] wf2020:
I don't have a problem with the battery when the screen is off. But once it's on it goes to hell even if I have the screen turned down to the lowest possible.

I factory reset and disabled bloatware with no effect.
[Samsung Galaxy S7 Edge Questions and Answers] berfles:
Yeah that's pretty bad. Here is my Verizon to compare to, it just dropped to 82% when I took the screenshot.
[Samsung Galaxy S7 Edge Questions and Answers] wf2020:
What's your setup? I had similar battery life as you the first two days and all of a sudden it dropped to these levels.
[Samsung Galaxy S7 Edge Questions and Answers] berfles:
Didn't do much, disabled the bloatware like you did, got rid of the VR stuff, auto brightness is on, always on display is on, I've been on wifi most of the day here. Other than that I don't think I've done anything drastic.
[Samsung Galaxy S7 Edge Questions and Answers] wf2020:
I'm going to reset it one more time and set it up as a new device instead of restore and see if that helps.

I also have been on 4G all day in an area with low-medium signal strength so I wonder if that is impacting it as well!!

Will report back shortly.
[Samsung Galaxy S7 Edge Questions and Answers] berfles:
Could be, Verizon has garbage signal here and I'm sitting at 2-3 bars all the time. 4G kills my battery on every phone I've had.

I also set mine up as a new device, always think it's a good idea to start fresh.
[Samsung Galaxy S7 Edge Questions and Answers] wf2020:
Back as a fresh phone. Charging up then will see by tomorrow.
[Samsung Galaxy S7 Edge Questions and Answers] LuigiBull23:
No issues on my end. Battery life has been outstanding. ☺
[Samsung Galaxy S7 Edge Questions and Answers] jmm22:
Has anyone confirmed that the system usage isn't simply recategorized processes that are being aggregated under a single name now?

I took a screen shot of mine. I'm on Verizon, nothing disabled, WiFi, used GPS for about 1.5 hours, and Bluetooth when driving (2 hours). Have Always On Display on, night time bar for 7 hours, and auto-brightness on. I'm at 24% with 4.5 hours screen time and almost 18 hours total.
[Samsung Galaxy S7 Edge Questions and Answers] laureanop:
They don't seem to me aggregate processes. Each app accounts for its own share of battery usage. That was my first thought as well.

And if that were the case: how do you explain the Exynos killing us in stand by time ( not to mention the consistent reviews that rate the SD battery life as disappointing/mediocre) ?

When you look at the Exynos battery usage it looks nothing like ours!!!

Don't misunderstand me, my battery lasts all day cause it's 3600 mha! But I have the feeling Qualcomm is still struggling with their SOC and 64 bit architecture ( the inclusion of the heat pipe is suspect)
[Samsung Galaxy S7 Edge Questions and Answers] greyhulk:
I have barely used mine today and I'm down to 37% after 11 hours of use. The Standby drain is ridiculous. And there doesn't seem to be any obvious cause. I'm really fond of this phone, but I have a week to take it back and I'm seriously considering it. I can also pick up the Exynos version for about $100 cheaper (sans Gear VR) and reports are that version doesn't have this issue. What's sad is, I just used Samsung pay for the first time (to get my $30 gift card) and was very impressed. I want this phone to work for me.

Something is keeping the phone awake for hours. Without root, I can't use Wakelock detector to figure out what it is.
[Samsung Galaxy S7 Edge Questions and Answers] Gentei0075:
Bull****.

Both me and my colleague have a S7 Edge. Since the update android system was eating battery like crazy. Since then we never got +40 hours stand-by and more then 3 hours screen time.

It's just now that my android system stopped eating battery i'm getting good battery.

The problem is well known also in Belgium but most people either flashed their phone back to stock FM where you get excellent battery life and others don't really give a **** and just enjoy the phone because in honesty. The S7 will get you trough your day even when Android system is eating battery.

I am using US ATT snapdragon v version. I have tried all the versions apc-apf. Sot is always around 6 hours with wifi browsing/YouTube and nothing turned off. Even if I turned off most of the things as people suggested, it is not significantly better. Android system is always around 15% to 20%. The battery life is similar to iPhone 6s plus with the same way of use. Given that ios is well known for its battery, I will stop trying anything else. People got better SOT simply because they use the phone in different ways
[Samsung Galaxy S7 Edge Questions and Answers] neezy13:
This sums it up, I think, for most users. Sure there are some people that may be having battery issues due to a bad flash or rogue app, but I think most of it comes down to use. I'm not going to disable all of the things that make this phone great just to eek out a few more minutes of SOT. My AT&T SD version averages almost 5 hours of SOT and 23 hours of standby according to GSAM and my usage includes gaming (Clash of Clans, Game of War), facebook, instagram, and tapatalk along with email and messaging, plus Android wear. No complaints from me because it is way better than my G3 and pretty much on par with my wife's iPhone 6+.
[Samsung Galaxy S7 Edge Questions and Answers] Cst79:
No, it doesn't sum up anything. It is a known fact that the SD820 had the drain issue from the beginning, while the Exynos did not. These are two entirely different phones, processors, graphics chips and radios are different.
[Samsung Galaxy S7 Edge Questions and Answers] neezy13:
I'm not denying that some people have had problems. My SD820 consistently reports android system as the highest battery user, but in my use the battery has been generally a non-issue. Sure, occasionally an app will act up and cause some weird drain and I have disabled some things like wifi and Bluetooth scanning, but I generally think that a lot of people just have unrealistic expectations for the battery life.
[Samsung Galaxy S7 Edge Questions and Answers] quarintus:
Can you be a little bit more specific. What part is not true? On another forum I am on, people asked for a new topic just for the battery drain, because most of the s7 owners got irritated by the messages about battery drain, because they don't have the problem and find irrelevant. I know 2 people with an s7, a dutch person and a belgium person. They both have newer software (like me) and don't have any drain.

That you and your coworker have the same problem, doesn't mean that everyone has it?

And for the suggestion that de S7 get's you through the day? Don't think so. Now I am 11 hours off charger with 2,5 hours SOT. Only 20% left. That's not getting through the day....

If everyone would have this problem, There would be much more attention in media, and on forums.
[Samsung Galaxy S7 Edge Questions and Answers] Theandroidfan:
It's annoying because I've had 6 Android devices now and they don't get good battery life (HTC Wildfire S, Nexus 7 2013, Galaxy S3, Xperia Z2, Xperia Z3 Tablet Compact, Galaxy S7) and that makes me think that it must be an Android problem because my Ipod Touch 6th gen doesn't have battery issues.
[Samsung Galaxy S7 Edge Questions and Answers] C0derbear:
I must have missed the note where an iPod Touch has LTE/4G/3G/Edge data, GSM voice, and FM radio on board. ;^)

Seriously though, comparing an iPod Touch to an Android phone is like comparing a nice turn-table to a desktop PC. Sure, they both play music *but* ... not so much the same otherwise.

I'd be more interested in the parallel iPhone 3GS/4s/5/6 battery use comparison to your series of android devices, in the same locales with the same use patterns.

I'm not disparaging he iPod please understand, I just don't think it's a valid comparison at all.
[Samsung Galaxy S7 Edge Questions and Answers] Gentei0075:
The part that there is no battery drain. Maybe not everyone has it but most people do. This thread even proves it.

I'm also on a other forum where there are a lot of ppl with problems.

The best proof for this was stock FM. No apps were draining and the battery was awesome. New FM installed and bam Android system got on top with 35-50% battery usage...

Maybe it's only a Edge thing? I don't know.

In any way even with the android system drain my S7 Edge got me trough the day.

Yesterday the same got my S7 off the charger at 4 in the morning and put him back on the charger at 22h30 in the evening. With 32% battery left.
[Samsung Galaxy S7 Edge Questions and Answers] sahil sharma:
Even an iPhone with all radios you mentioned blows a 3600mah s7edge out of water. The sleep mode on iOS is simply brilliant.

I hope samsung or google comes up with some solution.

Im on Brazilian pf8 with australia unbranded (xsa) csc and im not having any android system drain

Id really like to know why this is such an issue for only some people and not others

I've used avout 4 different firmwares and never faced this issue (touch wood) lol
[Samsung Galaxy S7 Edge Questions and Answers] Cst79:
Actually your phone has the drain issue. When on 4G only, the Android System drain will be lower, maybe a bit under 10% for some people, but on APC8 with 4G only, the drain is around 1% (and 3-4% on Wi-Fi). Here is a screenshot I took just now with my phone on 4G only:

This APEQ from TUR seems to be stable for now, get a little higher yesterday but even during the night the don't get higher.

Let's see if battery last second day.

I notice CSC TUR have some differences from others, i get 4.5G never seen this in my phone before, and bring BATMAN theme in stock.

This is not the APF9 .
[Samsung Galaxy S7 Edge Questions and Answers] C0derbear:
Doze mode works, basically, but it's a shame the OS isn't more draconian in forcing it. So many apps can prevent it from happening with various wakelocks. If those are out of the way I can't see complaint problems. For example, of I'm not using my Edge (at home or work, no BT audio streaming, etc., phone just idle) then it seems to use about 1% in the first hour and less than 0.5% battery every hour afterwards.

I would not mind if those numbers were halved but I can't really complain about them.

Android has a much bigger quantity and variety of "cats to herd" but that doesn't completely excuse that they haven't been able to do it.

FWIW, it's trivial to find essentially the same discussion focused on battery-endurance tuning for iOS 9. Your particular usage situation may be different but I don't think anything mobile truly has the Unicorn Battery Endurance for all users and situations. There's just too many internal- and external factors.
[Samsung Galaxy S7 Edge Questions and Answers] sahil sharma:
Yes agree iOS had been facing flak for battery usage of late. However, their standby drain is pretty nice.
[Samsung Galaxy S7 Edge Questions and Answers] B0bby_3rd:
I also experience this problem. My Nexus 4 battery drains so fast without doing nothing :(
[Samsung Galaxy S7 Edge Questions and Answers] gettinwicked:
I can't say that is true at all, at least from my observations. I have a lot of friends with iPhones, and between all of them, they've had every one. Not ONE of them has ever gotten completely through the day without charging their phone, a lot of times hardly using it. I've had two myself, the first one and the 3GS, and I know those aren't the best examples considering smartphones back then didn't have the battery life they do now, but on moderate use I had to charge them at 5-10 hours max. A guy I work with has the 6 and he's charging it by 1pm... When my last two HTC Ones AND my S7 Edge would get me from 6am until 10pm at night with still a ton of battery left, I'm afraid THAT blows any iPhone out of the water. It's not an Android problem.

Clearly the S7 Edge battery drain and overall battery life issues are software related on Samsungs end, and definitely on some of the apps we use too. For me, it's been more the latter. I changed some settings for a few applications including turning off location, disabling sending usage reports, and restricting background data, and my battery life shot way up. The versions of OS I've had haven't made much difference at all. Even an update that brought Android system drain way down didn't change the actual battery life much. But I'm on SD820, not Exynos.

Anyway, /end rant. Hopefully the Exynos software gets figured out soon!

My battery life is terrible. I'm using the phone for 2,3 weeks now and I only got 13-14 hours of battery usage :(

Yes my friend i am not trying to pick a favourite here. Firstly i am only referring to standby hours. As while using i am sure android and ios drink same juice while maybe watching a video etc.

If your friends are getting band standby hours, they definitely have GPS constant on and same with push settings. Three things -GPS always on, Facebook and push mail kill the iPhone.

Coming to the next point iPhones have a 1500 mah battery so if a person can last a day with that, thej its pretty nice.

On my 6 i would easily last a day with normal usage - bluetooth audio, fb, games and phone calls and whatsapp. Problem started two years after as my battery gave way ( due to my bad charging habit with that particular phone) and i moved to android.

And yes you maybe correct that its a samsung issue, but again the rogue apps draining apps and so many ads are jn google's hands. Peace
[Samsung Galaxy S7 Edge Questions and Answers] munkeybuziness:
So I was seeing really high android system usage like everyone else here. By noon the phone was typically hovering around 70% battery. I cleared the cache partition last night and now, close to noon its at 90% and android system is way down the list of battery usage, its at like 10% or so. Before it was fighting with screen as the top offender.

I have the Tmobile variant of the galaxy s7 (not edge) running the latest updates. I have a lot of things turned on that other posts in this thread recommend turning off. I have not done a factory reset since buying the phone a few months ago. I just figured I'd try the cache partition wipe and share the results. Looking good so far.

Not sure what info is useful but here:

Model: SM-G930T

[Samsung Galaxy S7 Edge Questions and Answers] Cinco5:
Just an update on my status, in the hopes it helps other.

Android OS and Services still see to suck a high-percentage of the battery, but the overall performance is strong.

I'm still on APB4 (replaced under warranty) and I'm having great battery life, especially compared to the APD/F whatever was most recent a month ago. I drain *maybe* 1%/hr in standby, the phone dozes a lot, and everything seems hunky dunky.

The only thing I've noticed is when I stream (stream, not save to device) Google Music, that my standby drain seems to go up to 3-4%. If I reboot the phone and dont use GM, I'm back to 1%.

I'm on the Verizon US version, so I'm not sure if there's an easy way to rollback, but I'm a major proponent of that idea for most sufferers.
[Samsung Galaxy S7 Edge Questions and Answers] Symphony0fLife:
It's not true for all iPhones. My old 5s for example struggled to get through an 8 hour day on light usage. I went from the 5s to a 6 and the life was horrible there too. The 6 plus was pretty decent (48 hours or so easy on standby, 5-6 hours SOT with no effort and moderate use through the day). My 6s Plus however could easily get 8-10 hours SOT with moderate usage, and no less than 6 with extremely heavy usage and lost virtually nothing overnight standing by. Days where I'd use it lightly or even moderately it was no problem going two full days without touching a charge and not really needing to until midway through the third day. And if I'd turn on power saving mode on that third day I'd eek out until bedtime on that third night easily. And that's without streamlining things, not worrying about how it's used or turning power using features off. That was just out of the box as it came with the latest version of iOS and everything that made it what it was enabled. If you started streamlining things, watching when LTE/Wifi were on rather than using both all the time, turning off location, you know... Tweaking things, 12 hours+ SOT is extremely easily had.

That was the biggest shock for me, switching to this phone which is my first Android device. Same usage when I first got it (AT&T version), I was struggling to get 3-4 hours SOT barely using it, only for things like emails, messages, browsing. Searching about if it was a bug or not was how I found this place and learned to start turning everything about it off. And you're right again. It's definitely on Samsung's end. Disabling virtually everything related to Samsung with a package disabler and all the "Edge" special features/advanced stuff has gotten the battery life pretty respectable. The gimmicks just kill it. They'd have a pretty solid device if they let it run pure Marshmallow. It was honestly shocking as the two primary reasons I bought the phone and moved from iOS were the camera, and the massive battery. How it has one this much bigger and still can't come close is absolutely staggering.

Edit: Granted, apps we use definitely affect things. On iOS as well as my S7E I don't game at all, very, very seldom watch videos and don't mess with things like Facebook (just Twitter as far as social media).
[Samsung Galaxy S7 Edge Questions and Answers] gettinwicked:
Yeah, apparently I lied, I haven't heard about the 6s plus battery life lol. That's good then. I can remember watching so many Apple iPhone announcements where they said the battery life was improved by whatever percent, then real-world usage, it still sucked...

Anyway, the S7 Edge DEFINITELY has terrible battery life out of the box, which is such a shame on Samsung, and a shame period. I did so many things to my phone to get really nice battery life out of it, yet my HTC One M8 got two days out of the box, I can't imagine the battery life if I had done everything to it that I've done to my S7.

Sammy REALLY needs to get it together. They've been seeing a downturn for the last couple years, but then this phone was very well received, at least at first, but with the poor battery life that most people won't know how to fix, they may see another downturn next year. Anyway, sorry for ranting again lol...
