im not sure if this is good or not. but 10 plus hours of battery and 3 and a half hours of screen time. near the end all the way to two percent i was tangoling with my girlfriend for an hour or so. CRAZY BATTERY LIFE ANYONE？

Yeah I am getting crazy good battery life too...Almost 22 hours off charger, 2 hours of screen time, and almost 50% of my battery remaining. This device is a beast, the battery is awesome.

Are you both using the same rom? Can this be the same with stock? My experience so far has been no where near that....unfortunately. Haha. Maybe I need to root and get this thing cranking!!!

No with stock I was getting much less.
I was running Gummy when that screen shot was taken. I have since moved to AOKP m3 but I don't find the battery as good so I am switching back to Gummy.

I consistently get atleast 15+ hours of battery with 4 hours of screen time on stock everything including battery. My brightness is around 25-30% percent though. I also keep my gps, bluetooth, auto sync off. Only use 2 widgets that refreshes automatically at a set time interval. Standby time is outstanding on this phone, it's just the screen that kills the battery. I can easily get through a week on standby.

Excellent! with heavy use of ~ 200 emails a day 1h on internet and about 30min looking up news and 1-2h of calls i get 12-16h.

I tried the best I knew how and I couldnt kill the battery for 2 days. I ran everything at once (not truly everything) and it just wouldn't die.

Battery is ridiculous. After diagnosing my wifi wakelock issue and installing jedi rom I get 4 hoursish per 1% when it goes into sleep, and that's in a basement mostly with horrible reception.

im getting worse battery life ever since the multiwindow update. not sure if anyone else has the same issue, but it seems like tmobile users are complaining about the same thing. it might be due to lack of battery calibration.

Well, here's a visual. Just achieved this impressive feat. 81 HOURS on pure battery! Almost 3.5 hours of screen-on time. I choose to not utilize my phone much over the holiday weekend, so that explains the low screen-on time. Regardless, I think these results are more than impressive. Nothing was restricted on my device. Live wallpaper going the whole time, auto screen brightness (usually a high setting), WiFi going, auto-syncing from emails to Facebook to Twitter, watched a bit of "The Dark Knight Rises" in full-1080p HD, made a bunch of miscellaneous phone calls. I am more than amazed at this phone and its battery. Haven't seen anything close to this in more than five years or so. These results are after updating to 4.1.2 with multi-window, and these are the best results I've ever gotten on this device.
On a side note, if anyone is getting results like the first poster with 8+ hours of screen-on time, it would really help if you described what you typically do with your phone and what you may have done to your phone. Just posting a screenshot tells nothing. You could be web browsing all day with your screen set to 20% brightness, and nothing more. What are you doing? Watching movies? Listening to music? Emailing? Texting? And if you're rooted that makes a ton of difference, so the results wouldn't be exactly truthful or accurate I should say.

Sorry for the lack of detail, I should have included that. I was browsing the net on wifi, playing Words, emailing/texting, various phone calls, watching youtube videos, and spending time on the XDA app. (of course)
I'm rooted and using clean rom 3.5. Auto brightness is on and I'm about 50% on the slider.
Here is where I sit today: (not much youtube though)

^^^ Thanks. So, that does change things, since you're rooted. The reason why I'm making a big deal about it, is because your results (and anyone else rooted) aren't typical results of someone stock. So a person not knowing any better would assuming they'd get your battery results from stock.

How is that possible? I use my note for about 5hrs of screen time and it's at like 3%. I am on an international rom and I undervolted along with perseus 1.8ghz kernel. Even when I did not have perse us, I never got above 6hrs? What settings do you use? I'm on wifi all day with the brightness All the way down. Please let me know! I really want to get that 8hrs of screen on time!

Clean Rom 3.5, I also make sure and close out of anything I'm not using. I also use the ES Task Manager widget to clear my ram before I power down for any period of time.
That's about it, besides not having a ton of widgets running.
I didn't get much over six hours of screen time with my Jedi Rom, but in fairness to it, it was my first rom and I don't think I did it quite right, installing other things with it that probably weren't compatible.

Like Dr. Evo points out, one of the great things about custom roms is they get rid of all the bloatware from ATT and other carriers. Stock I was lucky to have 1gb of free ram at any time, now I'm always around 1.1-1.2gb free without much effort on my part.

[Q] What is the typical battery life on a stock/unrooted One?

First off, I would like to say that I have searched several times for this answer to no avail.
I just came from a Maxx HD (XT926) which obviously had phenomenal battery life. So I'm not terribly surprised by the reduced battery life moving to the One. However, I'm currently only getting about 8 hours off of the charger with 2.5 hours screen time. Via GSam, there do not appear to be any terrible wake locks or rampant apps running in the background. I typically observe a wake time of +/- 10 minutes from my screen on time.
My typical usage right now is some heavy texting, light Facebook browsing, a GroupMe thread, and that's about it.
System settings are generally screen brightness on one bar (from the notification pull down, not sure what the actual percentage is), wifi/bluetooth/gps OFF, NFC and mobile data on all the time.
I have disabled the location via wifi options, so that's not currently a factor either.
What is the typical off charger and screen time for you folks? I love the phone, but a bit frustrated with the ~10% per hour battery drain at idle...
Thanks in advance for any input!

unrooted this seems to be the norm. there's a slew of VZW bloat apps that will check to see if you are using them once an a while, also blink feed refreshing often will have this impact.
right now on rooted Ecliptic rom i can get about 12 hours up time with 3.5 hours screen and still have 45% battery left. This is mainly on 4g some WiFi. this a 4.4 rom and has the options to turn things off the stock system cant like blinkfeed.
-wait till the offical comes out ( rummored to be at the end of this month) it should help-

Thanks, Synisterwolf.
That definitely helps put to bed some of the concerns I was having.
I'm definitely not opposed to rooting, but if I remember correctly, build 2.10.605.1 doesn't yet have an exploit, correct?
Again, thanks for the input.

That seems low to me, even for stock. Granted I debloated even when I was running stock, since I was rooted. I was getting closer to 3.75 hours of screen time for that amount of time off charger. But like I said, I was debloated.
Edit: I also don't use NFC, so that was off too. Not sure how much NFC affects the battery, as I've never really used it on any phone I've had.

there are a lot of things that can make the battery not last. i know the bloat the try to see ya is one of them
@ op no exploit as of yet. but on 4.4 you can go settngs > apps > all apps and click the ones you want to disable. its almost like uninstalling them for the non rooted devices.

I think there's a disable option option in 4.3 as well, so I'll give that a try.

With the help of Green Power Premium, my phone lasts 14 hours with moderate use and 8 hours with constant/heavy use. I don't use NFC or Bluetooth and turn off gps when I'm not using Google Maps. Honestly this phone is a god send coming from an Incredible 4G LTE

You can range between 8 and 16 unrooted stock. Depends on the use age and what you use. I do know with viper ROM and elemental x kernel its has superior deep sleep and hardly uses the battery at all. To give you an example of stock and other ROMs/ kernels I use to get about 14 while at work and finish with about 14% battery life at the end of my 12 hr shift. With my current setup I can go the 14 hr run and have between 75 to 65 percent battery life left and this is with sync active for mail Facebook and so on. So that's just an example of stock vs rooted.

With moderate use I drain about 40-50% of the battery throughout a 15 hour day. I'm running a battery saving script though which disables 2 minutes after screen off for cellular and 7 for wifi with interval updates. I also disabled a bunch of permissions for apps that I know I'll never need but for apps I frequent. On average I use my GPS for about 20-30 minutes of the day playing Ingress.
If I'm at work I only lose about 35% battery throughout the entire day. I only send/receive a total of about 100 text a day, and don't game other than Ingress. Very light Facebook use, browsing, and such.
Unrooted/Stock

Those usage times are pretty good for stock. I would be happy with anything over 12 hours right now.
I did notice bit better battery life after freezing/disabling some of the stock bloatware, but now I'm trying out an old fallback: JuiceDefender.
So far, it seems to be helping substantially (although it obviously only helps during idle times as it shuts off mobile data until the screen is on/unlocked), but I'll wait until I've had a full cycle before passing any final judgement.

run this:
https://play.google.com/store/apps/details?id=com.xiam.snapdragon.app
for 2 days and it will start controlling things in the background based off of how you use your phone. It will manage gps, wifi, data and not allow apps that you don't use regularly run in the background.

I had heard of this app, never installed it till now though. Would you suggest ditching the JuiceDefender app, or leave it running in conjunction with Battery Guru?

I would try just that and see if it helps. It just monitors your usage for the first 48 hours so if you are running other battery savers it might not work as well.

I'm totally stock and I regularly get 30 or more hours of battery. And I don't just keep my phone on the desk all day. I get 3.5-4 hours screen on time. 10% drain when not using your phone seems like an awful lot.
I have everything off that I don't need or use. That's pretty much it. I'm also on WiFi pretty much all the time too at home and at work. Don't know if that has anything to do with it
Sent from my HTC6500LVW using Tapatalk

Yeah, WiFi doesn't kill the battery nearly as much as the CDMA/LTE radio does. Unfortunately, I have both poor signal, AND lack of WiFi at work. Haha. Oh well.
30/3.5 would be fantastic. I'm jealous.

So question, where are you finding these screen on numbers? I looked under battery and the usage part shows apps but not screen on. The graph shows when the screen is on at what point during the day but no durations are given.

What could cause Android OS to consume so much battery?

This was after a day of using the phone for my normal usage I've used it from 7 am to 9:04 pm can anyone help me with this?

THIS. I was about to post the same question here in XDA. I have some screenshots attached if they can help you guys see the "extent" of the problem.

I didn't run a full-scale test, but 30 minutes of screen-on with only ~3% battery drain..... was superior to what I get right now, with all of my apps installed. If somebody else can test this I would be grateful.

Probably related to location tracking and Google now unfortunately.

It's the location tracking and Google cards and always scan for WiFi. I'm a delivery driver and phone was never going to sleep it was always tracking me. I don't use any of that anyway

I don't use Locations (but just about every other software feature is enabled) and I'm seeing great battery life. 3+ hours SoT is the lowest I get and that's on terrible signal mobile data, and 6 hours SoT on mostly WiFi usage. I will do a test with Locations enabled (with location based GNow cards) and see how much difference it makes.

Screen on time

It's amazing how much we actually use our phones in a given day, especially when we watch "videos"! Rate this thread to express how many hours of screen-on time you can get on the Samsung Galaxy S7 before depleting the battery.
Then, drop a comment if you have anything to add!

I've ran package disabler pro and disabled ALL but two or three bloatware apps.

My new S7 had a reasonable day I guess. Not too impressive but ok.
5Hr SOT fully drained.
A bit of GearVR and a bit of nav via google maps and the rest browsing.
I thought it might be better but im glad its not worse.
Happy enough.

4+ sot with auto brightness. About 1.5 hrs of deezer and 1hr of hearthstone.
Rest is twitch and a bit of browsing.
Also 1hr+ calls

I heard that Exynos has better scores on running browsers.
So the Snapdragon may not last as long as Exynos when browsing? Did I interpret it.correctly?
I use my phone very heavy on web browsing and I am on Verizon network using S6 currently. The rooted S5 runs smoother than unrooted S6 and lasts longer.
