[Samsung Galaxy S7 Edge Questions and Answers] Spewed:
The specs and camera were what attracted me as well. Most of all the battery attracted me. I feel deceived lol. It has in fact cemented the fact that I will never purchase a Samsung phone again. I'm not entirely ruled out on Android. HTC or a Nexus might be my next stop.
[Samsung Galaxy S7 Edge Questions and Answers] Symphony0fLife:
I almost went Nexus. I just really couldn't get over the camera and battery of the S7 Edge. Here's hoping an update or something is released that remedies all this. Though from what I hear about Samsung and updates...
[Samsung Galaxy S7 Edge Questions and Answers] Spewed:
Exactly and that's the problem. It shouldn't be dependent on Samsung to release an update. We should all have google software exclusively and rely on Google exclusive to give us an update. With that, Android would be more accountable and updates would be more widespread. Sure you can make a phone running google software but you better be doing just that, running google software. Not your own and not bloat. Google really needs to get a handle on his. Samsung is the largest problem too. HTC moves with haste now days. And Samsung says "oh whatever if you we give you an update you won't buy the next phone we release. Just shut up and keep buying our TVs, phones. Microwaves and refrigerators. THAT is the problem.
[Samsung Galaxy S7 Edge Questions and Answers] Theandroidfan:
This is just bloody ridiculous that battery life of this phone is so ****. I have the Exynos version and it drains so quickly in Standby. My Xperia Z2 never had this problem.
[Samsung Galaxy S7 Edge Questions and Answers] cavags5:
The bad signal you have its the worst thing for drain the battery when im in places no signal i have to turn off the 4G.
[Samsung Galaxy S7 Edge Questions and Answers] Symphony0fLife:
This. We have ****ty 4G/LTE coverage where I live. It's fine at work or in the city, but at home I have to turn off cellular data and use wifi. The same was true with every phone I've ever had. ****ty signals keep your phone active and searching for a better one and it zaps your battery like nothing else.

So after a full 24 hour period and following all the steps and recommendations of this thread I only was able to achieve 3 1/2 SOT yesterday, which I I'd like to reiterate is pathetic. After having exhausted all my resources I am considering flashing the old firmware. Fist I'd like to know if that is possible on the American versions. Secondly is it possible to use Odin on a Mac without some crazy work around?
[Samsung Galaxy S7 Edge Questions and Answers] Gentei0075:
Goddamn Android system anyone know how you get to the old first firmware??
[Samsung Galaxy S7 Edge Questions and Answers] cavags5:
Sammobile you will find what you need.
[Samsung Galaxy S7 Edge Questions and Answers] Spewed:
So we able to downgrade even on snapdragon?
[Samsung Galaxy S7 Edge Questions and Answers] cavags5:
Search for your model you will find it.
[Samsung Galaxy S7 Edge Questions and Answers] Spewed:
I've already downloaded APC8 I'm just wondering if it will cause harm to flash it.
[Samsung Galaxy S7 Edge Questions and Answers] cavags5:
If you flash any firmware for your model it will be ok. But only for your model.
[Samsung Galaxy S7 Edge Questions and Answers] Spewed:
Alright awesome. As soon as I have a chance to figure out Odin on the mac I'll give it a whirl and report back.
[Samsung Galaxy S7 Edge Questions and Answers] Spewed:
Okay, so I hooked up my old Windows PC, downloaded the firmware, and Odin. Soft bricked my phone, but fixed it in Smart Switch Emergency recovery mode. The error I get in Odin after attempting to flash it was SW rev Failed aboot fused 3

What does this mean, and is there any simple method of solving this error so that I can downgrade my firmware to APC 8 or am I forever stuck with APD8?
[Samsung Galaxy S7 Edge Questions and Answers] cavags5:
I see you have 935T, i think APC8 its only for exynos version.

Beware what you are doing, read more.

What firmware you downloaded?
[Samsung Galaxy S7 Edge Questions and Answers] Spewed:
It's a Tmobile firmware. It was a US Tmobile firmware. As per Sammobile
[Samsung Galaxy S7 Edge Questions and Answers] Spewed:
Does anyone know if it is actually possible to downgrade?
[Samsung Galaxy S7 Edge Questions and Answers] Symphony0fLife:
From what I have read you can if it doesn't downgrade anything in terms of security patches. Outside of that it seems you need root. Though I can't say firsthand as nothing is available for my S7 Edge on that site.
[Samsung Galaxy S7 Edge Questions and Answers] Spewed:
Well. It seems the June update has fixed battery drain for many. However. I'm on T Mobile and it would appear we haven't gotten that update yet.
[Samsung Galaxy S7 Edge Questions and Answers] Symphony0fLife:
Which June update? I mean, from which carrier?
[Samsung Galaxy S7 Edge Questions and Answers] Spewed:
Apparently Verizon and ATT have already received.
[Samsung Galaxy S7 Edge Questions and Answers] Symphony0fLife:
Oh, yeah I had an update from AT&T yesterday but it seemed to have mostly just been security fixes from what I read. Didn't alter my battery life at all (at least not yet) for better or worse. Still the same.

Edit: Yeah, AT&T is showing it was only a security patch. Hopefully Verizon and you guys get something useful!
[Samsung Galaxy S7 Edge Questions and Answers] Spewed:
Interesting those with Verizon are reporting better battery life. It'll be interesting to see what happens when I get it.
[Samsung Galaxy S7 Edge Questions and Answers] Symphony0fLife:
I'll have a look at what theirs was! Here's what AT&T posted about it - https://www.att.com/esupport/article.html#!/wireless/KM1086930
[Samsung Galaxy S7 Edge Questions and Answers] gettinwicked:
I'm on Verizon and mine has been the same. The update that fixed Android system and helped with battery drain was the early May update. The June update was only security patches.
[Samsung Galaxy S7 Edge Questions and Answers] Spewed:
So basically what we are looking at here is a line of essentially defective devices based upon a string of IMEIs ? Seems like maybe instead of exhausting all this time to fix an obvious problem I should just request a new device.
[Samsung Galaxy S7 Edge Questions and Answers] gettinwicked:
Not sure about that?

I've been getting 30-40+ hours of battery life on my phone almost since I got it. I changed some settings and such, most are the same as outlined in the OP, and my battery life is awesome. I don't think it's defective phones so much as bad software. And it's not ALL Samsung either, the biggest battery boost I got was from disabling the Google usage and reporting from the Google app, and even more from their keyboard app. Samsung seems to be playing around with their software. Hopefully they get it right soon and stick with it, although the snapdragon version seems to be good to go and has been. Exynos seems to be all over the place...
[Samsung Galaxy S7 Edge Questions and Answers] Spewed:
Well I've done everything including disabling background reporting. Turning off location services,etc. Still only can manage close to 4 hours SOT. Doesnt matter what I've tried. It's just terrible all around.
[Samsung Galaxy S7 Edge Questions and Answers] gettinwicked:
Well, I've never cared to see what my SOT is. All I care about is getting through an entire day and then some on my battery for my use. So, my stats might not matter next to yours. Just in case I've done some things you haven't, here is what I did:

Disabled usage and background reporting for all Google apps

Disabled Samsung security reporting as well as turned off auto updates for security.

I also check any apps I install for reporting. Plex was a big data/battery eater too.

Denied location permissions to a ton of apps I didn't feel needed it. As you are doing this, you'll get a popup saying it might need it to work for any apps that require it. I dropped from 35+ to about 15.

Restricted background data, again for apps I didn't feel needed it. Facebook and Messenger are big ones here.

Turned WiFi to off while sleeping except while charging.

Disabled nearby device scanning, Bluetooth and WiFi scanning.

Disabled some bloat in app manager.

I also installed Greenify for aggressive doze.

Turned off Google data backup. (This hasn't changed much though)

I use AOD, location to high accuracy, Bluetooth is always on (and connected to a smartwatch, and my car for an hour a day), Exchange services setup with push, Google accounts syncing whenever, etc.

Anyway, hope this helps. If not, you might try reflashing firmware. For T-Mobile, the battery/AS fix was the April update.
[Samsung Galaxy S7 Edge Questions and Answers] Spewed:
Thanks. I'll see what else I can do. I attempted to flash the APC8 firmware to no avail. Received SW REV fail aboot fused 3 binary 2 error in Odin and had to use emergency recovery on smart switch.
[Samsung Galaxy S7 Edge Questions and Answers] Spewed:
Pathetic. Everything disabled Facebook removed, Haptic feedback turned off. Location turned off. Google back up turned off. What the fkkkkk
[Samsung Galaxy S7 Edge Questions and Answers] tuk1maar:
Try redownloading APC8. It might have been a bad download.

Also, backup your data to a computer/harddrive and do not use Smart Switch. After succesfully installing APC8, just copy all your data back. IF your WhatsApp folder is HUGE (mine is about 11GB) then I recommend you to zip it first with an file manager before moving it to your computer (saved me 2-3 hours of waiting!!). Unzip it when it's back to your phone again ;)

I am on APC8 (stock) + root (for Zubi SoundMod). I refuse to ever update because with this firmware, my phone lasts insanely long. No mods needed! Just using it as is, without disabling a single thing. I'm getting continuously ~5 -6H SOT with ~35% battery left with ~15H - 16H standby. Autobrightness, 4G+, GPS & bluetooth are always enabled. WiFi is only enabled early in the morning and when I'm back at home after work at night.

I have tried multiple newer firmwares than APC8, but none made my phone last 2 full days when I needed it to. With APC8, on days when I'm at home, it actually lasts me 2 full days of heavy usage (indoors, only wifi, autobrightness never goes above ~50%) with 9 - 10 hours of SOT. APC8 also does about 1H SOT per 6-7% with light usage (WhatsApp/webbrowsing (easy sites)) at ~10% brightness for me at night.
[Samsung Galaxy S7 Edge Questions and Answers] Sartre:
I had to exchange my S7E (Exynos) two weeks ago, it was on APD1 when new and on APF2 at the time of the exchange and I was never able to get more than about 4 hours screen on time and 14-15 hours standby, even after disabling a lot of apps and services with Package disabler. Then I got my exchange, it came with APBF, which is a really early version with a build date in February and even older than APC8. I declined updating the software, set it up as my former S7E, and I´ve been getting minimum of 6 hours and often more screen on time consistently and 18-24 hours standby without even trying (4G on, Volte, sync, gps, bluetooth occasionally and wifi when available). All stock, nothing deactivated except a few apps I never use as seeing the icons annoy me (Google Drive, Flipboard etc).

I will as you just keep it on the old firmware as it works great, has been stable and gives me great battery life. I don´t understand how Samsung were able to make the battery life worse with it´s later updates, it´s not like they´ve given us new functionality which could explain it.
[Samsung Galaxy S7 Edge Questions and Answers] tuk1maar:
Great to hear that your problem has been resolved!

Making the batterylife worse... They did the same thing with the Galaxy S6 too! I had to keep using one of the first firmware released to have that device to last me an entire day with ~6 hours of SOT (also without disabling a single thing!)

I think that Samsung is doing this intentionally...
[Samsung Galaxy S7 Edge Questions and Answers] Theandroidfan:
How do I find out what's keeping my phone awake without rooting it?
[Samsung Galaxy S7 Edge Questions and Answers] Spewed:
I honestly don't think that my phone is capable of downgrading using Odin. Too many issues with this device in general. I'm fixing to claim it as a defective device
[Samsung Galaxy S7 Edge Questions and Answers] Gentei0075:
I actually tried it but used the FM of S7 instead of S7Edge.

Now the flashing failed in downloadmode. But since then my battery got better.

Android system was here allways between 35-45%

Now it's at 15-16%

Aggreed it's still high but still far better then before.

I also aggree that the stock FM was the best don't understand how samsung ****ed it up...
[Samsung Galaxy S7 Edge Questions and Answers] Theandroidfan:
Anyone?
[Samsung Galaxy S7 Edge Questions and Answers] kuuga1116:
My S7 edge(HK goods) drops 1% battery per half hour when it is standing by.

15% battery was dropped a night when I sleep (around 7 hours).

Is any other S7 edege battery dropping like mine?
[Samsung Galaxy S7 Edge Questions and Answers] Gentei0075:
Is your screen always on?

If yes turn it off. Mine dropped battery like that too i turned it off and it's good now.
[Samsung Galaxy S7 Edge Questions and Answers] naryraza:
My battery drain got way better after disabling google data backup (settigns > Backup and reset > Google > Back up my data). I get a bit less than 1% drain per hour at night (night clock on) and about 1% when leaving my phone in daytime with AOD on (although i didn't do anything to precisely measure it, but it should be more or less accurate)
[Samsung Galaxy S7 Edge Questions and Answers] kuuga1116:
I am afraid the screen will burn in,

so I have never turned it on.

2 years ago, I tried to use google backup for my LG G3.

When I restored my phone from google backup, nothing happened:eek:

So google backup must be disabled from the beginning when I get a new phone or restore OS.
[Samsung Galaxy S7 Edge Questions and Answers] Theandroidfan:
No bloody answer then. Cheers.
[Samsung Galaxy S7 Edge Questions and Answers] meyerweb:
Without seeing the rest of your battery stats this is meaningless.
[Samsung Galaxy S7 Edge Questions and Answers] cavags5:
Google back up only work if the sync is on.

I already try it to disable it and dont notice any difference.

All firmwares i try it the drain with all connections off its around 0.5% per hour.

And don't use airplane mode.

If want less than that its airplane mode or ultra power saving mode.

The battery life on this device is a joke
[Samsung Galaxy S7 Edge Questions and Answers] Ricardo_G:
i recommend you to try Force Doze, really it´s the only app that i know that enhance the battery life. Very use if you root, inclusive, very easy to enable using PC with adb without root. In my experience this app can be extend the battery life by 10 to 15%
[Samsung Galaxy S7 Edge Questions and Answers] nickrule1896:
Try wake lock detector light!(works for unrooted phones) I'm gonna try it now to save this joke of a battery.
[Samsung Galaxy S7 Edge Questions and Answers] cuezaireekaa:
Wakelock detector is awesome for non rooters. Only option out there. Plus it reminds me everyday why I hate Google services always bothering my device. Little bugger.

This is ridiculous. It shouldn't be heating up that much.
[Samsung Galaxy S7 Edge Questions and Answers] utkinpol:
struggle with this marshmallow version on S7 seems to be very similar to what i had to go over with shield k1 tablet when it got moved to 6.0.1. symptoms are same - damn thing does not go to sleep and keeps some internal stuff going on listening to wi-fi, sending stuff out, etc. so, on shield it was draining 5000mah battery 20% overnight.

this phone - sm-g930v, as i just got it setup, it went into sleep mode fully charged, in 3 hours i checked it and it shows me that estimated time to full discharge was 10 hours - it was very active instead of sleeping and i had all common issues attended - no feedbacks, screen off - all that stuff that OP posted on the first page.

yes, it was setup after factory reset. so, with little hope last night i did a full reset again, installed just a handful apps, nothing updated for samsung or verizon apps - left it overnight and after 9 hours or so it went from 100% to 97% showing 13 days of max time to discharge - means something in the marshmallow`s brains clicked and it went into proper full deep sleep mode.

i would LOVE to know what comtrols this non-sense as if you think it is galaxy s7 issue - trust me, it is not.

my s7 has 64gb PNY SD card on board, location services turned on, screen off, wi-fi turned off whie sleeping, google play games installed. more or less standard minimal setup.
[Samsung Galaxy S7 Edge Questions and Answers] Theandroidfan:
Help.
[Samsung Galaxy S7 Edge Questions and Answers] cuezaireekaa:
Go to settings /applications and tap on the right top corner and you'll see "apps that can draw over each other" in there you can toggle on or off which apps can get that permission. Or you can reset it in the corner also.

Hope that helps.

do you have a fix or just a complaint. I came to fix my phone and am very grateful for all the thing to try. They may not all work for every phone but it's worth a try and you can always set them back.

Can't say for sure, but it looks like it is based on how it flattens out when not in use. GSAM has a chart that will show you when the phone is dozing.

Is my phone faulty?

It's on full brightness btw
[Samsung Galaxy S7 Edge Questions and Answers] Theandroidfan:
This is the last straw lol. First the HTC Wildfire S, then the Galaxy S3, then the Xperia Z2 and now this phone... Android never changes. Their phones always lag and the battery life is poor. Unfortunately I've had enough after waiting years for this to change and I'm switching to ios. Maybe some day the Android lag will be gone completely and the battery life will be good without having to fiddle with your phone.
[Samsung Galaxy S7 Edge Questions and Answers] mjs2011:
Yikes! Yep, I did the same. The iPhone 6s Plus can last days at a time and you never have to worry about idle drain. Good choice.
[Samsung Galaxy S7 Edge Questions and Answers] Theandroidfan:
It's annoying though because I love Android but those issues I mentioned should of been fixed. It's 2016 ffs.
[Samsung Galaxy S7 Edge Questions and Answers] mjs2011:
Yeah luckily iOS is starting to become much closer to the android platform where it's not as bland as it used to be. Definitely check out the iOS 10 features. Looks awesome!
[Samsung Galaxy S7 Edge Questions and Answers] Theandroidfan:
Yeah and apparently the kernel in IOS 10 is unencrypted which means there's a performance increase.
