[Samsung Galaxy S7 Edge Questions and Answers] Symphony0fLife:
Yeah, it's pretty good. Honestly I was one of the "**** making phones thinner Apple we need more battery life!" camp until the 6 plus. The plus models really up the game. I attached my 6s Plus current battery stats. It's at 52%, almost 5 hours SOT (usage on iOS) and just over 94 hours standby. 52%, it's still got that much again before it needs to see the charger. They really are spectacular. Both Wifi and LTE on, no tweaks. Location, all that stuff is still on. Mail and messages all on push (everything with notifications on push really). The 6s Plus is a battery life beast unless you just constantly game or sit on YouTube or Netflix I'd imagine. So I just assumed the S7 Edge with a bigger battery would be even better, lol.

Honestly I like the S7 Edge better as a phone. I can live with the life I have now. It's just inexcusable in this day and age for a phone like this, a flagship, top level piece of hardware to be that poorly done out of the box. If I hadn't found this site when I did I was ready to go back to AT&T and turn it in before the 14 days were up and go back to Sprint and iOS.

Lesson learned though! Research before I buy next time. Next time it'll be a more pure Android device like a Nexus. I think this phone would be spectacular without all the bloat that just drags the life out of it. Like you say, most people won't know you can make it a proper phone by well... Turning off everything about the Edge that makes it better than it's competition. It's a shame really because the phone itself aside from that is MILES ahead. Battery life aside it destroys my 6s Plus on everything across the board.
[Samsung Galaxy S7 Edge Questions and Answers] Cst79:
Well, under controlled conditions (not the subjective stuff that people post around here) the S7 Edge gets a battery rating of 98h, while the 6s Plus gets 85h. The S7 Edge can call and play videos around 80% longer than the 6s. There's no need to write hunderds of lines when the difference is obvious and for all to see.

PS: All my iPhone-owning co-workers have chargers at work (most of the times their iPhones are plugged in :) ), I don't have one because my phone never runs out of battery during the day.
[Samsung Galaxy S7 Edge Questions and Answers] Symphony0fLife:
And here's a cookie for you! It was the first time since the 6 Plus that I've had to keep a charger on me at all times until I shut everything off. Mileage varies of course, as I said. And don't try to dictate what or how much I write. I was correcting mistaken information. And again, the 6s is not the same as the 6s Plus which the above screenshot is in reference to. The 6s is indeed as bad or worse than the S7 Edge, and the 6.

And if you're talking about the 6s Plus, I'd really have to see how they rigged the tests. Stock for stock out of the box with default apps on both (which I also tested) the S7 Edge was still nowhere near. Not even remotely close in either standby or SOT.

Edit: I see you referenced the 6s Plus at the start and the 6s later, my apologies. I'd like to see how they did the tests though, as again stock for stock (with the 6s Plus battery having a year's use on the S7 edge since it was brand new) with no additional apps installed on either, it literally destroyed the S7 edge in both standby and SOT, and not by a small amount. It was miles apart. Hence my search and finding these forums.

---------- Post added at 11:55 PM ---------- Previous post was at 11:47 PM ----------

And again I'd have to call that into question as far as results. The 6s Plus I posted the screenshot of is at 98 hours of real world use including SOT on a year old battery (94 hours if you leave that out) and it's at 52% left. How they rated it at 85 hours is beyond me. Definitely something slippery there.

Again I like the S7 Edge better as a phone overall, but there's no need for Kool-aid stuff. They just need to get the battery life sorted. Or at least sorted in terms of real world usage. There's real potential with it.
[Samsung Galaxy S7 Edge Questions and Answers] Cst79:
Again, S7 Edge Exynos is just much better battery-wise compared to the 6s Plus. It's so obvious it's funny :)

So after one day of usage, as i said earlier i got 14h of battery usage :(

This is ridiculous, S7 battery life is supposed to be better.

OS suck a lot of battery.

I'm using APF3 as firmware.

Good job I'm comparing an American (AT&T) S7 Edge to it then, isn't it? Can't argue with real world results. You can wish and ***** and moan all you'd like, link whatever youtube videos you like, I'm just stating and demonstrating via screens what real world use is like in my experience, stock for stock same things enabled on either device with identical usage. You don't have to like it. I don't like it, hell I like using my S7 Edge better. That's why I'm so pissed about how blatantly inferior it is in terms of battery life compared to a phone with a notably smaller battery.

I hope Samsung fixes the problem. I've been using my One Plus 3 (in the meantime) for over a week and Android System and OS are both under 10%.

Battery life on the Samsung Galaxy s7 edge

I just switched to the Samsung Galaxy s7 edge from the iPhone 6 and let me tell you… The battery life on the Samsung is way worse than the iPhone. I’ve noticed I’m down to 15 percent from 7 am to 10pm compared to the iPhone I would only be down to 35 percent. Talk about bad battery? The Samsung has taken the cake so far and now I’m stuck with it for another year or so.

May be u have something running in background. S7 edge has best battery in samsung and doze works perfect too no battery drain at all and 7 hrs screen on time
[Samsung Galaxy S7 Edge Questions and Answers] Skizzy034:
I've noticed the same. I had the 6S plus and the standby time was incredible on it. Not so much on the S7E.
[Samsung Galaxy S7 Edge Questions and Answers] sahil sharma:
7 hrs SOT is unbelievable. Can you please share a screenshot. Its sounds too good to be believable

Dont compare with iPhone. They are in a different league with battery management. Samsung needs to fix this.
[Samsung Galaxy S7 Edge Questions and Answers] Cst79:
Except that everytime they get tested in similar usage patterns by any website or magazine, the S7 Edge comes out on top :)
[Samsung Galaxy S7 Edge Questions and Answers] sahil sharma:
S7 edge will xome out on top especially while using the phone. A youtube video playback will drain higher percentage on iPhone than s7.

Only the standby times are a saving grace for iPhones.

7 hours SoT is easy. I'm at 5hrs with 40% battery
[Samsung Galaxy S7 Edge Questions and Answers] mawan100:
I get 7 hours of SOT while streaming videos constantly with 10 hrs of the charger but if I use the phone for 20-24hrs, I get 4 hours of SOT because the standby time sucks even with airplane mode on.

I had testing some firmwares and I see that android system and Android OS both, one more , one less, are consuming around 100 mAh for each 10%.

And i try all firmwares.

This is my use.

Using 4G more, or both , or only wifi.
[Samsung Galaxy S7 Edge Questions and Answers] kitch9:
I have just uninstalled the Facebook and Twitter apps today.....

Huge difference to the Android System drain. 12% instead of 25-30%.

As a bonus I've realised that just running them through chrome and putting shortcuts on the home screen is a far superior way of doing things.

I don't know what Facebook are up to but they are hiding a lot of background battery use when the phones screen is on that is clear.
[Samsung Galaxy S7 Edge Questions and Answers] Cst79:
The sad thing is, Facebook will remove the messaging capability from the mobile web interface over the next weeks.
[Samsung Galaxy S7 Edge Questions and Answers] naryraza:
I used to have about 5h30 to 5h30 SOT (which is actually great) and about 20h before having to charge the phone. I just disabled the google data backup (settings > Backup and reset > back up my data) and i am now up to 6h30-7h30 SOT. I see some of you guys here have +8 or +9 SOT, but 6h30 combined with a total charge of +22h is more than OK for me. That's with a mixed usage between wifi and 4g, i get more than 24h with wifi only and a bit more SOT.

I'd probably gain more battery time if i uninstall fb, snapchat or instagram, but again 6-7h is fine with me, and i'm not quite okay about using less things on a device that costs that much.

That being said, i use black material theme, twidere instead of official twitter app, facebook, instagram, some web browsing (medium usage i think), location is turned off when i don't use it, AOD on (yeah, i'd probably gain some % if it was disabled but i juste like it lol), some gaming (nothing very hardcore though), a lot of messaging (telegram mostly).

I also installed good lock if it can be relevant to anyone, but created a "everywhere routine" setting instead of just using the default one (this one caused me about 15% System UI draining).

I generally got these draining infos within GSam : Android system 10%., android OS 5%, google services 3%, System UI less than 1%

If you go to settings in chrome and use desktop version you can access your messages without the app
[Samsung Galaxy S7 Edge Questions and Answers] kitch9:
Messenger with permanent power saving doesn't seem to affect battery, I'm going to try both ways though and see which I prefer.

Is there any way to get chrome to request desktop site on a specific page instead of that option affecting every page until it's turned off?

[Samsung Galaxy S7 Edge Questions and Answers] kitch9:
Thanks,

I'm literally blown away at the difference from removing Facebook apps. 10 hours off charger, 80 minutes sot with 70 minutes of calls today and I'm still sitting with 74% battery, I'd have had 50-60% at best before.

Definitely something dark and shady happening over at Facebook.
[Samsung Galaxy S7 Edge Questions and Answers] Naemion:
It is constantly connected and searching for new content...of course it's going to to drain battery.
[Samsung Galaxy S7 Edge Questions and Answers] C0derbear:
It's not dark and shady - it's known they continuously send data Home, and you can't stop it (much). I discovered how much back with my GS5 and have refused to install their apps since then, at all (ok, almost, I still haven't purged the Oculus stuff from my SG7e). I used to disable the MQTT services they use, which may be possible with Package Disabler, but that would not solve the issue for me that it's insulting they want two phat apps on my device. *forget it*

Some felt it was keeping their Android system usage very high. I'm not sure it's the reason but YMMV
[Samsung Galaxy S7 Edge Questions and Answers] cavags5:
Doesn't notice any difference, and is a useful feature.

Android System is about apps,

I did in my note 4 a reset , just don't install any apps., and use only wifi when i came at night , and Android system is 1%. The phone has sim card , disabled Google apps and a few more.
[Samsung Galaxy S7 Edge Questions and Answers] leonguerrer0:
guys i just downgraded my firmware to apd1, how can i prevent the system update? even if i turned off the automatic update its still showing , thanks
[Samsung Galaxy S7 Edge Questions and Answers] Cst79:
Why did you do this ? You should have downgraded to APC8 or lower. APD1 has the worst of both worlds: poor battery life and not up the date security-wise.

If the system update icon appears on the upper left of the notification bar, you can't stop it unless you reflash.

When you reflash, you must remove the SIM and do not enable Wi-Fi until you disable automatic updates. Then enable Wi-Fi and mobile data. When the update screen appears from time to time (it will appear less and less) you must press the "later" button.

Hi.. Wiping your cache partition, did you lose anything apps wise on the phone?
[Samsung Galaxy S7 Edge Questions and Answers] bluemu:
Has anyone else installed the latest security update from T-Mobile (appeared in the last couple of days) and noticed a difference? I installed it last night and there seems to be a very noticeable difference in my battery life, but it's also too early to be sure. I noticed that my battery drain decreased big time right after installing the update last night and is still going strong today. However, I'm concerned that the performance may go down over time for whatever reason. I feel like this has been a pattern for me in the past. Hoping this is not the case, since I'm loving my battery life right now.
[Samsung Galaxy S7 Edge Questions and Answers] anibalhuneeus:
Which security update? July?
[Samsung Galaxy S7 Edge Questions and Answers] bluemu:

[Samsung Galaxy S7 Edge Questions and Answers] quarintus:
So could someone try this out.

Yesterday I disabled: google services framework, google play store, and google play services. (if i couldn't disable them, I would delete al storage). Then I would activate them again. The apps are now back to their first versions.

Last night, I only lost 2% battery in 8 hours. So I need some other people to try this out en see if their standby drain goes away.

NOTE: android system and android OS are still high, because when not in sleep, they are still draining...
[Samsung Galaxy S7 Edge Questions and Answers] cavags5:
Android system and OS drain if you have conection on.

And if you have good signal wifi and 4G drain less.

But with ACP8 with wifi is android system is always low.
[Samsung Galaxy S7 Edge Questions and Answers] quarintus:
I know! but how is that a reaction to my post. I am considering a partial fix to the problem.

I dont like ACP8 because there are no DPI settings. Also, you don't have he latest security patches.

Also, I am saying that it doesn't change anything with android OS and system, but does let your phone go to Doze much better.

Third: I have wifi and 4g enabled. Switching between both. Still get a good result now :)

Now on my second day with the fix, and batterylife has much improved. Mobile standby is high on the list. Really happy :)

Also I would like to note that there is a new update rolling out. APG :)

So second day after disabling and then enabling google: play, services and framework, my battery life is still improved! Mobile standby actually is in the battery usage (meaning it's dozing off :D)

Give it a try :)
[Samsung Galaxy S7 Edge Questions and Answers] Cst79:
Well, everybody has his own definition for "improved". For me, disabling core features does not mean "improved". How about some battery life screenshots ?
[Samsung Galaxy S7 Edge Questions and Answers] dynospectrum:
When you have battery drain, whats in your Running Services list?

Developer Settings/Running Services
[Samsung Galaxy S7 Edge Questions and Answers] quarintus:
You are not disabling anything! You are just resetting the services. You turn them off, back to factory settings, then turn them on again, and they update to the newest versions. There is no loss.

Screenshot:

First day: setting everything up after reset, trying out this pokemon go :P, then appling fix. Charge (not even full) flat part: me sleeping. Then some usage, little peak: navigating in my car while on charger. Then some usage. Then sleeping again. There is a little bit more drain, but that is because I now have no wifi, and the phone is on 4g.

As you can see: mobile standby is in the top 3 :) So since 10-7 I never charged to 100% yet. Like 80%. And at this moment I still have 47% left

So total if you remove the first part let's say 14 hours, I'm am now on my phone with 1 D and 4 hours with almost 50% battery left.

EDIT: adding photo's from services running. Doesn't show anything though.
[Samsung Galaxy S7 Edge Questions and Answers] cavags5:
If you never charge to 100 you never know what consumes for every charge.

And i don't really care about security patches.

For now ACP8 can use 3rd party apps.

With firmware after we can't.

Doze in my phone never works because if isn't a call is a messege.

I think i did that once in my s6 and doesn't notice anything disabled Google play and services.

But i will give it a try just to see in s7-edge.
[Samsung Galaxy S7 Edge Questions and Answers] quarintus:
Don't forget framework. But if you have no drain a.t.m. you won't see any improvement?
[Samsung Galaxy S7 Edge Questions and Answers] dynospectrum:

[Samsung Galaxy S7 Edge Questions and Answers] Cst79:
I am a standby time junkie. Here is my latest standby time of 2.5 days (61h) with APC8 firmware. SOT is also over 4h, 100% web browsing so Chrome also consumes quite a bit of battery. A mix of 20% 4G and 80% Wi-Fi. Nothing disabled, even Bluetooth is enabled (I have a smartwatch connected). No battery saving applications used.

What I did since last time:

- Enabled fingerprint unlock (I didn't have it enabled until now)

- Disabled usage data access for all applications minus Google Play Services in Settings->Lock Screen and Security->Other Security Settings->Usage Data Access (one user on the forum recommended this and I tried it - it does seem to have an effect).
[Samsung Galaxy S7 Edge Questions and Answers] kitch9:
I have a theory, on the later firmwares I think mobile radio active reporting has got moved/hidden to Android System. I've just moved back to APC8 and although Android System has dropped dramatically, Chrome has moved to the top of battery stats with a similar time of mobile radio active reporting to what Android System was reporting in the newer firmware.

Could Chrome be the problem, could someone on the new firmware disable it and see if Android System improves?
[Samsung Galaxy S7 Edge Questions and Answers] cavags5:
Chrome is not the problem.

Could be google services but no chrome.

Never use chrome and flash all roms .

ACP8 is that have lowest android system.
[Samsung Galaxy S7 Edge Questions and Answers] quarintus:
it's not chrome, It's still there with chrome disabled :) If chrome is taking battery, disable it, and enable it again for a fresh install. Usually removes the problem.

In APC8, there should not be any drain.

Ok, so please read this thread. I'm already got a lot of positive feedback regarding improved batterylife. NO Consessions! :) Fixes your drain in standby.. Not when in use. (only got feedback yet from exynos users, so need other to try this too :) )

Actually Chrome is more efficient than the Samsung browser, battery-wise. But the Samsung browser is much faster and has ad blocking support. I am now using Chrome and there is a significant difference in battery life (I use the browser a lot).

I have an S7 edge from Bell Canada (SM-G935W8) running the latest software available (6.0.1 security patch April 2).

I don't have any real issue with use or SoT, rather it's simply battery discharge over night. I keep it off the charger while I sleep, with it being at 100% when I go to bed. I generally get about 7 hours of sleep, and my battery hovers around the 85% mark when I wake up. 15% drainage over 7 hours seems incredibly excessive.

When I first got the phone, it would usually drain about 3% overnight. I've tried resetting the device twice, but my 15% overnight battery loss remains fairly consistent. There is no noticeable change if I use Power Saving overnight. If I use Ultra Power Saving, the battery drain hovers around 10-11%.

Have you checked if something is keeping it awake all night ? That looks like a steep incline and definitely not normal drainage over night.

Youll want either wake lock detector, or better battery stats.

Thanks for the tip! My device isn't rooted though. I don't really have an issue rooting it, but it seems like an extreme level of action needed to get decent battery life.

I tried grabbing Package Disabler Pro and then basically disabling *everything* that wasn't needed, and last night my battery only drained 5% overnight. I have a sneaking suspicion that it's either some piece of Samsung software, bundled bloatware or carrier bloatware that could be the issue. I don't know why that package wouldn't show up in the battery stats though...

One night doesn't mean a ton though, so I'll need to test this over a longer period of time. Ultimately, it's an irritant more than anything else, as my battery still more than gets me through the course of the day. It's just the sort of thing that bugs me, as a flagship device in 2016 really shouldn't exhibit this sort of behaviour.
