Second charge to 15% 20.5hr with 2hr SOT, 6hr Spotify streaming and 1hr call (both via BT).

Android System taking up 24%, Android OS taking 13%.

Still kinda meh life. Gonna test with Always-On turned off.

This with WiFi turned off when not connected, turned off the ability to always scan, and restricted location to cellular network.

How many with so-so life using Always-On? I am almost wondering if they did their "should only take 1%/hr" testing on the screen itself measuring it's draw over an hour, and not the actual drain on a full phone during that time....

I can't remember what I uninstalled but it was basically anything that can be uninstalled in the T-Mobile and Samsung folders in the app drawer. Disabled apps are as follows:

Android Pay

Device Unlock

Google App (not necessary unless you use Now or open the app for search instead of your browser)

Google Play Movies

S Voice

Samsung Billing

Samsung Galaxy

Samsung Gear

Samsung +

T-mobile Name ID

T-Mobile TV

Voice Service

There are still a ton of apps and services that we are not allowed to disable but are clearly bloat. Waiting patiently for root.
[Samsung Galaxy S7 Questions and Answers] Th3Bill:
One thing I hadn't really noticed too much of previously was that on screen 2, there is a widget for T-Mobile TV that seems to auto-update content every so often. At first glance, I thought it was a static widget just showing that you could use it and you would have to click on it. Today I noticed after a few wakings that what was being showed was different each time, so it's gotta be holding system awake to some extent. Anyone with bad battery delete this widget? I'm just trying to narrow down things I can do that doesn't involve freezing tons of apps.

Oh geez, mine is arriving today. Now I'm wondering if I should hold off on opening the box to make returning it easier. I guess rooting will fix the issue, but battery life is a huge issue for me.

Thoughts?
[Samsung Galaxy S7 Questions and Answers] zcubed:
Honestly I haven't had any major issues with battery. Even before disabling apps I got a full days worth of battery. That's a full day of installing and configuring over 75 apps without charging even once. Over 4 hours screen on time.
[Samsung Galaxy S7 Questions and Answers] Tekogremista:
Even with this issues I'm having more then 4 hours soc. I will get better probably 5 hours soc after figure this thing out. So no worries
[Samsung Galaxy S7 Questions and Answers] fzfrank:
Thanks. I think I'll unbox it. I'd hate to have to look at that box for a few days.
[Samsung Galaxy S7 Questions and Answers] Th3Bill:
It's not earth-shatteringly terrible per-se. It's just not what I was expecting with a "bigger battery" and a "more efficient processor". I use my phone a lot...streaming music, phone calls, txts, etc. I'm still getting enough that if I was to take my phone off the charger at 6am with a full charge, I would be able to get through until after 10pm before I'd be in line for a charge.

To compare:

My G4 would have gone 24+hrs. However, that's only a 6 core processor and was no where near as slick as this phone is. I loved that phone, but it definitely had its lags.

My iPhone 6sPlus would last 30+hrs. However, that phone with a case is SIGNIFICANTLY more bulky in my pocket and the camera doesn't compare....not to mention on recent updates, it became HIGHLY buggy.

Also have to take into consideration that it charges really fast, so even if you're able to plug it into the wall w/quick charger or to car with a 2.1A charger, you can get 20%+ battery in a few minutes.

Go ahead and open it and use it. If you got it from T-Mobile, you have 21 days to send it back if ordered by phone or on-line....and that's 21 days to have it in the hands of the shipping agent (UPS/FedEx), not fully back to T-Mob.
[Samsung Galaxy S7 Questions and Answers] fzfrank:
Great point!

People with this phone literally only being in the hands of us for a day or so *****ing about battery life is premature
[Samsung Galaxy S7 Questions and Answers] Th3Bill:
That came in handy when I switched over to TMob and got the Z3 then realized after 14 days that my friends weren't pissed at me, the messaging app didn't like playing with WiFi calling. :)

Go ahead, dive in, and play with it for a week or so. Believe me, I'm an HTC fan at heart...they just haven't made anything worth buying in the last 23 months since the M8, and I fear that the M10 will be another M9-like disappointment. So far, the S7 is definitely making me not miss HTC quite as much. Especially like that it has some of the Sense-like bits(like the Zoe-like short video picture feature and where the gallery makes little slideshows of your pics from days/events. Having kids, these features are awesome for me to share with my family). Sorry to hijack...just inserting my $0.02 on the device.
[Samsung Galaxy S7 Questions and Answers] cepheid46e2:
I feel the same way, the M8 was awesome and Sense is by far the best launcher but HTC dropped the ball on the M9.

3 hours SoT still 41% battery. I think I can break the 5 hours barrier. For me this is perfect. 12 hours of battery, 3 SoT, still 41%

You could be getting a lot more if Android System was not chewing 500mah per day. The battery under use from this guy is best I've ever seen. It's the stupid standby time killing us cause of that bug

Other than the overheating cpu and crap camera how did they drop the ball?
[Samsung Galaxy S7 Questions and Answers] misiokicio:
Well boys... maybe the drain will differ with Exynos... so far obviously all devices here are SD, the phone itself need at least few days to settle itself down too, can you guys also state whether is edge or flat.. as the difference might be huge between them too, thanks

Ok not seeing this. Forgot to put mine on charge last night at 33.woke up with 32 percent
[Samsung Galaxy S7 Questions and Answers] kash20:
Getting my S7 next week, I'd actually be quite content with 4 hours SoT, I only get around 3.2 with my HTC M9 and feel I'll get a lot more with the S7, seen threads on the Android subreddit where people are posting up to 6/7 hours easily. Sure there are numerous factors involved, but I think the average user won't face too many problems

did anyone tried to disable the always on screen to see if there is a change in the android os drain?

One of the first things I turned off but still drains
[Samsung Galaxy S7 Questions and Answers] tifosi256:
^^ This.

My current phone (S7 on preorder) is a MotoX (2014). For the first week or so the battery was absolutely terrible. It would come off charge at 6am, and be dead by 7pm. After a couple of weeks and full charges/discharges, was getting a day and a half on a single charge. These batteries just need some bedding in. It might even be a calibration thing and when the phone thinks it's 0%, it's actually got another 20% in it.

So yeah, I wouldn't worry just yet. If it's doing this after 2 weeks, then worry.
[Samsung Galaxy S7 Questions and Answers] Th3Bill:
I agree. Also, gonna have some updates over next couple weeks as more carriers release device.

Standby on mine was much better last night. Only dropped 3% in 6hr (always on turned off). Up from 10-12% last couple nights

Hi guys, anyone try 4G with s7 all day.

Just to compare to my s6 to see if worth the upgrade.

Thanks in advance
[Samsung Galaxy S7 Questions and Answers] omeryounos:
I'm getting this with XEF on Galaxy S6. Probably you guys can try the same on your S7. And without package disabler and without removing smart manager. Seems like doze is working perfectly.

What i have done.

1. Restored (reflashed) phone to XEF factory firmware with Smart Switch. Google and Samsung accounts signed in. Around 56 GB data including Apps, Games, Movies, music etc.

2. Didn't run the smart manager. Didn't enabled any permission in smart manager for security or disk cleaning etc. In summary don't run it ever.

3. Wifi setting to turn off on sleep except on Charger.

4. Google app, music and movies, playstand disabled.

5. Gmail sync off. Rest of sync on

6. S voice disabled.

7. Rest of everything stock.

What u mean by this? I had my phone on LTE 12 hours yesterday (work WiFi sucks) and it was rock solid. Battery didn't drain more on the cellular network than it had on wifi.
[Samsung Galaxy S7 Questions and Answers] cavags5:
Im usually not in the same place every day, i already test with good and bad signal, bad signal i make less half an hour.

But is always around 4h sot.

Stock with package disabler.

I assume that s7 makes 5 or 6h sot in 4G.
[Samsung Galaxy S7 Questions and Answers] km8j:
Ok a few things all....

1) This is not related to "calibration" or anything with it being the first week. We know this because 'android system' is using huge amounts of battery.

2) I noticed that if I leave the phone for an extended period of time, Doze kicks in and standby time is fine. I.e., lost 2% in 5 hours overnight. As soon as I pickup the phone though and start using it, thats it. I picked it up, used it for 10 minutes, battery dropped 1% and then I put it down. 5 minutes later of screen being off, I lost another 2% - all android system.

Just used Greenify to enable aggressive doze, lets see what it does.
[Samsung Galaxy S7 Questions and Answers] Zethmir:
I am doing a full day (820 version) with 4G on - just because someone asked for it. This will be a heavily used device in a real world environment so don't expect 20 hours of phone time but I will do my best to ensure that it isn't a terrible number. Everything will be enabled - wifi nfc location bt sync even outlook with 4 emails..... and AOD. I use llama to disable wifi and put the volume in the car up to 15 so that is the only time WIFI will be off.

I'll post the numbers at the end of day. Already put in 40m of screen on time with Pandora streaming over BT on the drive into work lol.

Has anyone tried a version of the Google Play Services that is designed for Marshmallow, like the most recent 8.7.02? We have a version for lollipop installed 8.4.89.

EDIT: I know google play services isn't the one being reported as the battery drainer but it does change A LOT in the background and could still be the culprit.

[Samsung Galaxy S7 Questions and Answers] JDM9499:
My S6 had Google Play Services draining a significant amount of battery usage, right under Cell Standby. It's non-existent on my S7 and actually says 0% battery consumption since last charge. Last charge was 8 hours ago.

So, for my device, it's not the culprit. But good idea to update the play services nevertheless. :good:
[Samsung Galaxy S7 Questions and Answers] km8j:
What is android system use?
[Samsung Galaxy S7 Questions and Answers] mklpickle:
Did you update? My battery life isn't where it should be, but I just turned off 'Always On' feature. According to BetterBatteryStats, I'm now actually going into deep sleep alot longer than I was. (from 5% to 75%). Battery usage is reflecting that, so I'm hoping, in my case that was the cause, but really want to use the 'Always On' functionality.
[Samsung Galaxy S7 Questions and Answers] PunishedSnake:
Around 790mah
[Samsung Galaxy S7 Questions and Answers] km8j:
Yea.... There is the issue. How long were you off the charger? I could hit 6hr SOT also over 7 hours. Over 20 hours, no shot.
[Samsung Galaxy S7 Questions and Answers] PunishedSnake:
12hr
[Samsung Galaxy S7 Questions and Answers] Pneumatic:
That's been my findings too. I uninstalled all the apps I don't need and am also trying Greenify to get some of the background stuff to settle down.

I wish there was a way to pinpoint what's actually triggering the Android OS and Android System since they include a LOT of various things. At least then we would know where to start.
[Samsung Galaxy S7 Questions and Answers] se1000:
FYI, for T-Mobile folks (I think that's everyone so far), try disabling VoLTE. Seems to have reduced my battery usage but I'm still testing today.
[Samsung Galaxy S7 Questions and Answers] Pneumatic:
Where's that located? I must be missing it in the settings.
[Samsung Galaxy S7 Questions and Answers] km8j:
Yup. Remember without root, regular Greenify isnt useful - it is the new aggressive doze piece that is.

Killing VoLTE is a huge loss IMHO. Quick connect times, high speed data while on calls and more. Someone else can try it hah
[Samsung Galaxy S7 Questions and Answers] se1000:
Open the dialer, more, settings

I bet a good chunk of that 'Android System' is probably Facebook. They hide a lot of their stats.

I think we all agree this phone gets good battery life but there is no excuse for Android System to use 600 - 800mah per day.
[Samsung Galaxy S7 Questions and Answers] Zer0_:
I'm a little confused with all the replies in here.

Some of the screenshots that have been shown seem fine to me (I think 12-15 hours of battery life is pretty decent).

Are you guys getting much less?

How much of an effect is the Android System Services having on the battery?
[Samsung Galaxy S7 Questions and Answers] vash429:
What does factory reseting it do? Does it get rid of any of the bloated t-mobile apps... my battery has been really bad but I got it last night and have not changed any settings
[Samsung Galaxy S7 Questions and Answers] Zethmir:
Alright - I agree battery life is great. Much better than what I would get from my Nexus 6. But if they could explain the high "Android System" drain with a reasonable explanation I would be fine with that. I think most of the complaints are more "what if" it didn't drain - imagine how much more on time we would get.

BTW this is with 4G not LTE as someone asked for it. Also everything else on (AOD - BT - WiFi - Location - NFC - EVERYTHING). Samsung pay used two or three times. 2 hours of Pandora streaming via BT in the car. 40 minutes of Milk Music streaming via BT in the car. 50 minute work phone calls with full bars and HD voice. 40 minutes of FF Record Keeper with an RNJesus roll on a 50 mythril (had 100 first one was ****ing 2 gold rest white). Also Outlook with full notifications on 4 email accounts.

Ok so 2 days in a row the first bit drops fast & then levels off... Im currently at 14hr 39m on this charge & it says I have 11h 12m remaining...

Comparing this to my G4 this time of day I was normally in the 15-30% range & currently I am at 48%.

The only tweak or change to anything I did is I have changed the launcher to google now & installed the google messages app to use instead of stock. Oh & swype instead of the crap ass samsung keyboard.

[Samsung Galaxy S7 Questions and Answers] cavags5:
Thanks friend.

Android OS its a lot of apps and bloatware pushing the system, and in 4G is more.

In 6.0.1 you can see what apps drain the battery.

And if is bloatware you can remove it.

You can in 4G lock data background like Google play services and others you don't need.
[Samsung Galaxy S7 Questions and Answers] Andromendous:
I was just thinkin. You know, I notice that some things seem a little weird. For instance, when I got the notification to update google play services, it LITERALLY took 10 mins for it to install it. I can tell when i install an app, its pretty slow. It makes me wonder, could the people getting good battery life have cpu's that are somehow stuck with the slower power friendly cores on, and the people with poor battery stuck with the stronger cores on? It just seems weird, that some things are super slow and some things seem normal. I dunno. But here is another screenie of my batt stats. Im just mind blown.

Great suggestion, I've actually gone through and disabled everything I don't use or plan to use, in general my phone is running pretty lean.

Regardless of what it shows on the usage monitor, I'm of the opinion that I can confidently get 5+ hrs of SOT consistently. I don't really care where it goes, that's great battery life IMO.

5 hours SOT over 10 hours way different than 5 hours SOT over 30 hours

No clue but so far better sot from 100 to 75% got 2hr sot
[Samsung Galaxy S7 Questions and Answers] ElBeaner:
Sadly I think it still does, which is why I have a Tmobile Cell Spot for my home to help boost cell performance at home (this way I don't have to rely on wifi calling at home - stupid radiant heat barrier). When I go to friends house and if I have signal issues, I'll usually turn on Wifi calling only when I need to(or if we've left the kiddo with a baby sitter).

It causes the phone to constantly be connected to signal in stand by and you'll notice Standby start to be a large percentage of battery use.

That's pretty good. From 7am until now, I've used 58% - 2h8m SOT and streaming iheartradio(screen off)
[Samsung Galaxy S7 Questions and Answers] PunishedSnake:
Turned off volte and WiFi calling got this. However it was on lte for about 2hr45 before switching on wifi.

With them on I would be at 3hr at the 50% mark

Two apps I find using lots of battery on my device and contributing to the Android System battery drain are Knox and Help. In application manager, look those two apps up and see what they are reporting for battery usage for you.
[Samsung Galaxy S7 Questions and Answers] km8j:
What you probably aren't realizing is that every package is bundled together for reporting. If you look, every single package in Android system will show the same value
