OK.. My Idle battery life has been better over the last couple days. Phone is actually going into doze now (as reported by GSAM).

Android System Usage still seems high (25-30%), but the actual drain doesnt seem as bad.

Verizon S7 Edge

Auto Brightness

GPS, Wifi, BT, Data: ON

AOD: OFF

EDGE Clock: OFF

OK Google from any screen: OFF

I also turned off features in Google Now that rely on location.. like location based cards or how it tries to remember your parking location. I never use that stuff anyway. Also standard stuff turned off like twitter and facebook sync. Never understood why those apps need to sync when you see everything when you open them up anyway..

you can see where it levels off is when I was sleeping..

This is from another night and you can see that the idle usage was down to .07% ... still not on the level of my iphone6s+, but tolerable i guess.
[Samsung Galaxy S7 Edge Questions and Answers] berfles:
My usage is still high, but last night I only lost 2% while I slept. I'm on day two again, started the day with 50% battery and 3hrs screen time. I have zero issues making it through two full work days on a single charge, and probably two full days total.
[Samsung Galaxy S7 Edge Questions and Answers] Nan Da Man:
Same here. Two full work days, about 6 hours of sot.
[Samsung Galaxy S7 Edge Questions and Answers] NemesisHunter:
Tested my Galaxy S7 Edge's doze mode last night (Exynos model) by fully charging it to 100%, then unplugging it before going to bed.

Enabled Settings:

GPS enabled

Bluetooth enabled

Wifi enabled

Data enabled

Do Not Disturb enabled

Disabled Settings:

OK Google (from any screen)

Ambient Screen Display disabled

Here are my results:

To summarize, it drained 9% over a 7h14m period, or 1.2%/hour, when left idle.

I feel it's draining too fast for a device that was left untouched overnight (considering all the modes I've left enabled).
[Samsung Galaxy S7 Edge Questions and Answers] shineyads:
Same here - my Exynos drains about 10-12% overnight, so people need to get over the snapdragon thing because it does happen on Exynos too!

Two things... My battery got AMAZINGLY better yesterday.....

I've narrowed down a potential culprit...curious if anyone else can test.

SO .... I have a Gear S2. Back when I was on a Note 4 the only way hangouts would work on the S2 was by installing Android Wear.

On Wednesday night I uninstalled Android Wear. Subsequently I didn't notice until this morning that I wasn't able to reply to hangouts messages from the S2 anymore....so I reinstalled Android Wear. ... My battery has been dropping like a rock ever since.

I'm going to uninstall Android wear again tonight....go all weekend...then reinstall.

My Note 4 battery had been horrible ever since I got the S2...which is primarily what pushed me to upgrade to the S7.... now i'm wondering if Android wear was the issue then too....
[Samsung Galaxy S7 Edge Questions and Answers] dmrnhs:
Verizon may have fixed the android system issue!!!!!! I just installed the newest update they pushed today and I know I've only had it installed for 30 minutes, my top battery drain in poweramp. I've been listening to music since I unplugged. I'll update later to see if my android system drain is down. Gsam is only reporting android system at 3%

Edit: I lied. Android system is slowing creeping back up to what it used to be
[Samsung Galaxy S7 Edge Questions and Answers] vineet381:
AT&T pushed an update today which I installed, anybody knows if it makes any difference to battery life?
[Samsung Galaxy S7 Edge Questions and Answers] km8j:
Man... I thought you were onto something. I have a S2 as well and had Android Wear installed but on my warranty replacement I never installed it. I have cruddy battery as well :(
[Samsung Galaxy S7 Edge Questions and Answers] fluidj:
Make sure though...I don't remember actively installing Android Wear...so I assume it came pre-installed...OR it just installed from my Google apps backup in the background.
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
I think I got rid of my Android System drain but I can't know for sure yet since my phone has only been unplugged since 10AM this morning.

Last night I did another Factory Reset and this time I opted out of the Google scanning for security issues and I opted out of uploading data to Google to "IMPROVE" our experience. Those are the only things I did differently this time.

Maybe this was the reason our phones weren't really dozing/deep sleeping as much as they should have. Maybe the device was just uploading more statistics in the background than it should be. Maybe the Google servers were connecting to our phones more than they should have been?

I'll know for sure tonight but my Android System usage has read 9% ever since this morning at 10AM. Mind you it hasn't gone below 30% for the past week.

Today, I also drove around for 2 hours while eating lunch and going to a couple stores. My battery stayed at 90% the entire time. Before, it would have gone down at least 2% during this time.
[Samsung Galaxy S7 Edge Questions and Answers] km8j:
yea i checked, but thanx. definitely not here. i have the gear plugin though. went and added some more. I'm up to 95 things disabled. cant do much more than this.... if i keep disabling stuff, ill be stuck with a nokia 3390.

2 hours off the charger. 111 mah from android system, 20 min of voice calls and 22 m of screen time. down 10% :(

Done and done. Sent them a pretty long email basically saying, "look, we all know how to do factory resets, tweak sync schedules, etc. We dont need help with that. We need you to look at the software of the phone and see if there's something wrong on that end."

The Galaxy S7 model number isnt in the drop down list.. it appears you can just type it in though.

[Samsung Galaxy S7 Edge Questions and Answers] zathus:
It's all a matter of what you use to divide for. Like on your screen shot I notice youtube is your top app . YouTube is pretty friendly to the battery. If people like to game, the results are going to differ greatly from yours. If someone spends most their time using the browser and that's it they're going to get excellent battery life compared to someone who plays nothing but Grand Theft Auto.

Posting battery results in this thread is pointless. The only time it's relevant in this thread would be, I had high android system drain, then I did xxx and now this is the result.

It's not a debate whether there is or isn't higher drain then stock Android or exynos version while idol. There is. How it effects you is all about your usage. its still there..sitting pretty at number 1.

My results are pretty good and I'm pretty happy with them. Doesn't mean I don't see that it could be better.
[Samsung Galaxy S7 Edge Questions and Answers] laureanop:
Exactly! I can go 24 hrs with 7 hrs of sot pretty much everyday . But that's not the point !! With a much bigger battery and a smaller screen than my previous Note 5 battery life is marginally better in my SD S7E, when it should be considerably better given the supposedly more efficient CPU! And this is due to the excessive Android System/OS consumption!

Please stop denying there's a problem! The stats are very clear from SD and Exynos!!
[Samsung Galaxy S7 Edge Questions and Answers] mdewyer:
Very interested to hear if this makes a difference!
[Samsung Galaxy S7 Edge Questions and Answers] LuigiBull23:
Nope, not for me. Android system is number 1 but do I care? No because it affects my usage in ZERO way. I manage just well over 2 days with 7hrs screen time nearly every single cycle. These kind of results have already exceeded my expectations. Therefore, I along with others with similar results have absolutely nothing to complain about. This is as good as it gets. Sorry others aren't as fortune but it is what it is. The stats speak for themselves. Enough said.
[Samsung Galaxy S7 Edge Questions and Answers] laureanop:
You have great battery life and so do I , as I did with the Note 5 and yes the s6! But you can't ignore 90% of the reviews that describe the S7 SD battery life as good enough to last through the day but not all that impressive!

Brother keep in mind that we're dealing with a 3600 mha battery and perhaps the most efficient display ever! I understand you're more than happy with your battery, but don't deny what the numbers are showing!

With the Note 5 And the Exynos 7420 I had virtually 0 idle drain and the battery graph would show several flat lines throughout the day. The only flat line I get with this phone is after a couple of hours of going to bed!! That's unacceptable !! My deep sleep time averages 70% for the day while the Note 5 was always above 85% ( Luigi you're no rookie, you know how important that is). Another fact you can't deny is the CPU usage time ( it's 50 to 60 % higher than it should be)

So both of our battery lives are very good, but they could be great and Samsung shortchanged us with a lesser CPU ( bear in mind the reports that side by side the Exynos is smoother and faster than the SD and that the Exynos kills the SD in RAM speed)
[Samsung Galaxy S7 Edge Questions and Answers] LuigiBull23:
You make very valid points.
[Samsung Galaxy S7 Edge Questions and Answers] meblah741:
Hello everyone,

I thought I would chime in here after reading everyone's posts. I too was having the same problem. My battery was draining 5%/hr on idle. I went to bed with an 86% charge and woke up around 68%. My wake time was showing almost 9 hours. All this happened Thursday night. After reading the posts here I downloaded the package pro disabler app, turned off ok Google from all screens.

I first noticed an improvement when I disabled the setup process. I went from 5% to 2.5%/hr. So after that I decided to disable gear and I don't know if that's the reason why I got better battery life last night or not. I also went into safe mode for an hour or so yesterday before I disabled gear. Maybe going into safe mode disabled other processes??

BTW, I have the SD820. Hope this helps some of you.

Also forgot to mention I disabled wifi scanning, wifi was off and overnight I had so not disturb on. I should note though that had no impact to battery life. I tested it before and after and was still getting 4-5% battery drain. My Bluetooth and NFC are always on.
[Samsung Galaxy S7 Edge Questions and Answers] zathus:
You have something else going on. Cell standby is killing you. Disable all the T-Mobile apps with package disabler see if that improves that. That might at least get rid of the high cell standby.
[Samsung Galaxy S7 Edge Questions and Answers] Pilz:
After my last update from T-Mobile here's my horrible battery life:

2% battery loss overnight- 6hrs. Beginning to think android system is not a battery drain or even if it is I can live with it. My main issue is reboots after installing tmobile update. As you can see in the graph
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
My S7 Edge is now getting great standby drain ever since disabling what I mentioned.

If others want to know what I disabled you can check out my post from yesterday.

By the way, I have not disabled any packages. I haven't even downloaded a package remover. I did disable a couple apps in the systems application manager but that's about it.

As of right now, my phone has been off the charger since 5AM this morning (Eastern Time) and am sitting at 96% battery life. I have about 10 minutes of talk time (VOLTE) and sent/exchanged roughly 15 test messages. Also WiFi is not longer making my device get hot nor is it draining the battery.
[Samsung Galaxy S7 Edge Questions and Answers] msage:
Extremely interesting. Is there a way to change these settings without factory reset?
[Samsung Galaxy S7 Edge Questions and Answers] viking2.0:
I did disable Google app scanning and as I just posted above had 2% drain overnight. But I feel even with that enabled I would have got very less drain
[Samsung Galaxy S7 Edge Questions and Answers] squallz506:
I got my android system drain from 25-28% down to 17% by disabling the improve Google setting after a factory reset. Now to break my battery records.

Edit: it appears to be slowly climbing back up, now it's at 19%
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
My phone is no longer reporting Android System as the highest drainer of battery. Cell Standby is at the top for me and then Facebook. I only browsed Facebook for roughly 5 minutes too.

My phone is sitting at 95% battery with 11 hours of use. It's telling me I have another 47 hours to go before it dies.

If everything stays this way then I'd say the battery life on my phone is stellar.

Again, I have not disabled any packages. I only disabled a few apps through the application settings.
[Samsung Galaxy S7 Edge Questions and Answers] Juuls:

[Samsung Galaxy S7 Edge Questions and Answers] Juuls:
No, power save on, sync. off, wifi off, data on, DND on, AOD off.

I also just installed DU Battery Saver so wonder if it can get better, I did a lot with the phone today cause I had to solve a problem with my Google Contacts not syncing. If i didn't solve this I could have easily pulled thru the night, I started fiddling around 40% juice left.

Oooooh. Thank you! Mine was already off so that doesn't seem to be the fix for my android system drain
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
There is actually two different settings that requires your phone to upload statistics to Google's servers.

One is for security and one is to improve Android along with user experience. Then Samsung has one too.

I don't know where they are at in the settings though.

Also, if you're planning on doing a factory reset, make sure you clear the cache first. I also did this.
[Samsung Galaxy S7 Edge Questions and Answers] nyt:
I already had google usage and diagnostics off. I was still getting android system drain. Disabling app scanning now and testing again.

I don't know about anyone else but I received my Edge update (AT&T) and standby time is significantly better. My location challenges all my phones (high rise, near highway/bridge/river, concrete walls, etc) but standby time is finally ~2.2%/hr. I'm also connected to a Moto 360 via BT all day. I only updated yesterday so I'll know more in a few days but looking better right now.

Mine if I remember is high too. On my nvidia shield tablet i got 1% Android system drain lol.

I'll check what the s7 has tomorrow but I can tell you I was 100% at 12:04 and now 94% at 01:29. Doze did kick in AFAIK because I sent 2 emails to myself (Gmail and Samung email) and there was no notification for neither.

Curious what Android OS will show in the morning. AOD is on.
[Samsung Galaxy S7 Edge Questions and Answers] Willyman:
It's so bizarre this whole thing.

Yesterday I had the worst case of drainage yet. Took it off the charge after a quick top up from 40% to full. After an hour of casual usage(some browsing, some YouTube,...) it had dropped to 80%. Phone feeling warm throughout.

Checked the stats... Android System 45%, Android OS 20%... That's nuts.

Rebooted the phone and things reverted back to the "normal" 20-25% Android System and 10% Android OS.
[Samsung Galaxy S7 Edge Questions and Answers] Juuls:
3% battery loss overnight in 8 hrs: this time I left data on all night, wiffi off, AOD off, DND on, Power Save on and Sync was on.

I also installed DU Battery Saver + DU Speed Booster before i went to sleep. I only used the Optimize & Boost function and did not set a default schedule.

- When I first got the phone it would drain 6% over the night with above settings but without DU Apps.

- If I also turn off Data and Sync the drain is 2%/8hrs and if I only leave on Wifi it's 2%/6hrs.

- My phone signal at home is pretty weak (mostly 1 or 2 bars, sometimes 3) where the phone sits but calls rarely don't get thru.

- While testing the above settings in the past week I managed 4 days of use (just short) with 8:33 hours SOT and Doze only worked 33% of the time.

So, there you have it, these values should be just about same for a

'good'

functioning SD820 version as opposed to my Exynos.

I now hope my own battery OCD calms down a bit cause I'm starting to irritate myself with this obsessive battery monitoring :cyclops:
[Samsung Galaxy S7 Edge Questions and Answers] razorseal:
Here are my results overnight. Don't think this is very impressive
[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
They aren't the only thing draining the battery and at this point, I don't even know if they are at all.

I was sucking down a lot of power even with the gear and Knox packages disabled.

I then cleared my cache and did a factory reset and my battery life is better than its ever been. I went to bed last night at 11:45pm with 74% battery life remaining. It was removed from the charger at 5am and I had almost 3 hours on screen time.

FYI....after the factory reset I haven't disabled a single package. I only disabled a few apps under the application settings. The only thing I did different this time is turn off Google statistic reporting.

So if Knox was really draining the battery then it would be on mine considering I haven't disabled it.

What's my best way of doing a factory reset? I read Google can lock you out for three days or am I crazy? Lol I'd be willing to do this as I'm used to flashing Roms so it wouldn't be a big deal to me to lose everything if I can achieve a better battery life.

[Samsung Galaxy S7 Edge Questions and Answers] jrwingate6:
Because, it's the system apps draining the battery. I was still getting battery drain with no apps installed so it has nothing to do with an app we downloaded.

Now after clearing the cache and doing a factory reset my phone is magically getting great battery life with about 30 apps downloaded and ZERO packages disabled.
[Samsung Galaxy S7 Edge Questions and Answers] Ghstudent:
So what I'm seeing is that system reset is actually helping the majority of the people doing it.. Is there anyone who did a reset that did not experience less drain?

Found this good review that shows the battery difference between the exynos and snapdragon processors. The snapdragon battery life isn't bad by any means but is clearly not on the level of the exynos for some reason.
[Samsung Galaxy S7 Edge Questions and Answers] Beefheart:
Exynos version here. I've performed a lot of optimisations using Amplify, Greenify and Titanium Backup, removing and cutting back on a lot of unused services. I'm getting a good battery life now, but it still doesn't seem to be any better than my old Note 3. I'm sure things will improve though as updates come out and custom ROMs that contain them.
