I bought a used Galaxy S3 just a few days ago and have had pretty crappy battery life, or at least crappy when compared to what I read in some reviews. This guy claims that a 90 minute video with sync going on in background drained the battery to only 82%. I'm seeing much worse numbers. Leaving the screen on for one hour drained the battery to 75%. Other than occasionally touching the screen, I didn't use the phone for anything else during this time. Screen brightness was set to about 60% and wifi was off. The phone is rooted but still on stock UVLH2. Screenshots of the battery usage screen are attached. Does it sound like I have a bad battery?
Most people are getting about 5 hours of screen on time per battery charge.
At that rate you get 4 hours thats what I average with 2 different batteries.

But I'm not using the device for anything. There is nothing running. You can see in the screenshot that the only two things using the battery are the screen and the system process, which is at 2%. Is the number cited in the review I linked to in the original post simply BS?

I don't understand what you are trying to say. I left the screen on as a mean of draining the battery that can be easily and consistently reproduced. Browsing the web, playing a video, or running some app introduces additional variables that I can't easily control for. If, as dkmlb says, most people are getting about 5 hours of screen time while also using the phone (browsing the web, playing a game, etc.) and I'm getting only 4hrs while not using power for anything but the screen, then there is possibly something wrong with my battery.
you need to use the phone more for the battery to adjust itself. I set the brightness at 50, wifi on (when outside, 4G on), GPS on. My daily usage includes checking email, reading news on Pulse, check google play,etc yesterday the total screen time on was 3 hours. All of that last over a day (24h) and I still had 10%. (I dont play video, music, games, etc..)
What you said was true I didn't even think about it, but give it a couple days and cycle the battery normally (don't let it go past 3% with out plugging it in) and use it as a daily use and see if its good for you.

Im so impressed! did have a s3, and I thought the battery wasnt very good with heavy usage. Fully charged it once, so its on its first cycle, and its lasting as if it will withstand heavy usage for most of the day

The battery is simply phenomenal.
I'm getting a full day of heavy usage on mine, around 7 hours screen time!!! I take it off charge around 7-8am and by the time I'm in bed at 1am it's ready to go on charge again. :good:
Does anyone stream their music? I take my OneS off the charger at 7 and the battery is pretty much dead by 1:30 pm with about 3-4 hours of streaming SiriusXM radio and some web browsing.

WiFi always on
about 1 hour bluetooth handsfree
14% battery left
brightness about 50% + automatic
Very, very impressed!
I could not do even half of this with my One X.
Nothing different tbh.
Added more apps, thats about it.
Anything I can use to monitor?

I do a lot of gaming, web surfing, fb, txting, listening to music and it usually lasts almost 24h. It's quite good compared to the old phones I used. If you dont do as much as I do, it might last 2 days.
I actually love how long the battery last..

Note2.. yep
This is my first day using the phone
4hrs of screen on
Lots of net surfing, youtube so on
All on 3G pretty happy with battery and it should get better after a few battery cycles

Dude, I totally see this happening on mine... I had mine since launch the N7100 version. Today I was just monitoring the battery, taken 2 calls and one of them was a voip. No data, all wifi but my battery draining stats are very similar to yours...
Started to get paranoid...

Yeah the battery is awesome! I'm shocked every time I look in the corner and the battery always seems to be a solid block of green!
I've had the Gnex, One X, LG 4X HD and S3 and the battery on this is probably twice as good as the best of them which was the S3

Lucky you! I've been working on tweaks to my stock rooted system to get past 7 hours with data on. I'm going to test tomorrow or Monday.
Looks almost exactly like mine.
Man what are you guys doing? Here is mine over the past few days.
Mind you this is about 15-30 of minecraft and Epic Pirate Story during lunch. Full data and sync on with 4G/3G but mostly WiFi. About 30-40 min of web browsing. Tons of google talk and feedly news reader. Tons of pictures and about 5 min of video taken for each of those days.
Only mod to the phone is the camera mod.
pictures may be out of order but I think you get the just of it.
it all comes down to screen on time. less than 4 hours of screen time between charges is not very good.
Seeing a little over 4 hours of screen on time while using the AOSP roms.

I already hit a 5h 15m mark once letting the kiddos watch a movie off the internal and then Netflix. The movie was hour and forty and Netflix took it down the rest of the way streaming on 4G.
on average I get roughly 2.5 to 3.5 hours in each charge which I'm fine with considering I could barely hit 8 hours before a dead battery with 2 hours screen on with my old Epic 4G Touch.
I'm sure I could get 4 hours screen on time if my phone wasn't the on sprints horrible network. I'm constantly searching for a data signal in Arizona. I do usually get just over 3 hours screen on and about 18-21 hours total between charges.

Sounds like you have an app in the background doing something. Even my Epic 4G Touch wasn't that bad. Maybe a weak WiFi and or cell signal causing the battery to drain faster.
An update was this weekend.
Unplugged phone at 908am saturday morning. Plugged it in Sunday night at 1145 with 5% battery.
during the weekend I played Epic Pirate story for 25 min. Shot 150+pictures. Shot about 18 min of video. Wifi coverage was 50% of that at home and the rest was 3G/4G. Oh and streamed two episodes of revolution VIA FTP from my home Android server on 4G. Other than that I cruised the web and used feedly for news feeds.
At work I generally drop 3% in an hour and half without touching the phone with 50% cell signal and corp WiFi at 25% signal strength. At home I have an Airave and pull from WiFi(I have to access points in the house for solid coverage so signal never drops below 50%) and I drop around 1% per hour. Signal really matters when it comes to battery life.
I believe my screen on was around 3h40m.
So all in all I am impressed and love this phone!! Just wish the camera wasn't so crappy.
im at 7.5 hours with 66% left.
Light to moderate use including web browsing and about 15 min of angry birds star wars. Rooted Stock Rom with Loki's IA tweaks as my daily.
Sigh. 35 percent.

I tried that for two days in a row and didn't see any difference in battery life. Performance was untouched as well so I think that maybe it's already on and/or the app is broken.

Yep that is about what I get with screen on less than 2 hours.
So yesterday I played Epic Pirate story with 50% brightness for 45 min and dropped 25% in battery. Then about 10 min after I stopped playing my battery jumped up 7% LOL. I am seeing this a lot with this phone as it seems that the way the battery is read throws lower % than what is actually there. Odd thing...

For me I don't see any real drop when texting or anything like that it's only when I run a game or something that really pushes the phone. When I stop playing I'll be at say 50% and then when I look at my phone 10-15 min later it's up to 55-59%. It's like the app reading and watching the battery miss reads it during an intense usage period.
Here's me.
Unrooted.
seems like battery dies sooo fast when listening music.

What sort of battery life are you all seeing with this years note? come from the ipad 3 where i usually saw 10-11 hours screen time and 2-3d standby, today is the first time ive had it from 100% and i only lasted 6 hours screentime with 7 hours overall on time, i still havent run it down completely yet but surely i should be getting more than this?
Its such a shame because i love it so much, but i cant deal with this short battery life
It's much better than that. I found it better after a couple of charges. I rooted mine and deleted or froze b.oatware and I get 13 hours heavy use

I came from an ipad 3 as well and had the same problem until I disabled several apps, turned off GPS, etc and over the long weekend I was getting ~12 hours of web surfing.
I haven't rooted yet so that should be a number that can improve. I'm sorta trying to wait for a root that doesn't trip knox. I don't want a custom rom so no reason to install a bootloader and lose my warranty if I can be patient. Tried Cydia Impactor but I had already upgraded to MK1. I'm wondering if the shipping rom (P600XXUAMIE) might have the 4.3 vulnerabilities unpatched.

I thought it was more, but looking at the list.. go to settings, General, Application Manager, select the prinstalled apps you don't want running all the time and click Turn Off. I've turned off BlurbCheckout, Businessweek+, NYTimes, Polaris Office, Screen Saver and Twitter. I think more important was turning off GPS, Screen Rotation, Bluetooth, Reading Mode, Smart Stay, Smart Pause, Smart Scroll, Auto Brightness then adjusting the screen brightness to something a bit less retina searing than the default.

I've had mine since Saturday soooo, 5 days now. I get easily 10-11 hours of screen time. I loose about 1% per 8-9 hours in stand by and i loose about 9% per hour of video streaming from either my Netflix, HBO GO, or Slingbox account and that's with brightness about or just above 50%. I'm also NOT rooted yet. Totally stock with just certain apps turned off and i restrict a lot of the background data on individual apps that i don't need running background data
Have you guys try using this damn thing at 100% while indoors? It hurts the eyes with a white screen.

Hmm, I think I misspoke about the background data on this tablet. I do that religious with my phones (Bionic, GS4) but I went to look at what i did and there is no option to turn off background data. I would normally go to settings>data usage and tap whatever app and the check "restrict background data". I must have thought I did that on this tablet but obviously not.
i think the battery life is great on my tablet - i dont game with it - today it has been running for 13 hours 48 minutes with 5 hours and 48 minutes of screen on time and battery is at 52% - not rooted yet - i have everything i dont use turned off ( ie. smart stay/scroll, air view ) and running nova laucher prime and dont use power savings mode

I dunno, doing pretty good over here. Rooted, but have no froze anything. Only rooted to get gameCIH installed screen is between 25% and 50% brightness depending on what im doing or where i am. I mostly just use it for playing a few games here and there, taking notes during lectures.. etc. This is about typical, sometimes I get a little less, screen brightness seems to play a huge role in battery drain (obviously) but ive never run it dead during the day.. ever. I start every day with 100% charge and dont usually plug it in till I go to bed. If I have a charger around and im not doing anything ill plug it in (I mean.. why not) but I don't ever have to "worry" about it going dead on me.
I'm currently on 9 hours of battery time, probably at least 4-5 hours of that is screen on time reading comics or doing sketchbook pro pictures.
Battery is on 46%.
So yeh, battery is fine. Brightness is about 30%.

Right... It's better then an IPad. I doubt the IPads beat 11-12 hours of screen time at roughly 50% brightness and an IPad has a smaller screen and less pixels to power.

Dude, just turn it on and use it. The days of cycling a batter (let it drain and then charge to full) were over in the 90's with Ni-Cad batteries.. these do not develop a memory. From dead, the tab will take 5-6 hours to charge with supplied charger and in the wall. Using it while charging will still cause it to lose battery but a a much slower rate.
So after purchasing the Nexus 7 (2013) 16gb WIFI edition I noticed a problem with the battery that is really bugging me. Im on stock non rooted 4.4.2 and the battery is HORRIBLE. Moderate use finds me having to charge the thing almost twice a day. Its especially bad when im watching a youtube video or streaming a movie on netflix (Non GPU intensive gaming also), it will go down about 1% every 3 minutes not exaggerating. I have heard stories on here of Nexus 7 owners getting like a day or two out of the battery. Is there some kind of ROM or kernel out there that is good battery life? Is my tablet just a defect?
p.s. I have my brightness medium, GPS off, and i keep my WIFI always on.
Battery isn't intended to go a day or two and haven't heard of anyone's doing that. I use elementalx kernel, slightly over clocked, get about 10 hours with moderate use. Hard to tell now because I keep mine on a wireless charger when I set it down.
Netflix does drain the battery a lot. If you watch it all day you're gonna have to charge it. Can try out any of the Roms and kernels, see what works for you.

My nexus battery isn't that different from yours so i'd say it's not a defect from your tablet but it's our battery that isn't that good. I use sinless rom with elementalx kernel with cpu at 1.8 ghz and if i play need for speed for a couple hours and watch 1 or 2 movies drains really fast. the battery is the only thing i hate on this tablet, that and the fact that there's no sd card slot..
my nexus 7 also does not make much more, usually 7 hours screen time. it is often enough to look at a video on google play, and surf a little with wifi

Standby time is where the battery lasts for days, actual usage will dictate how often you need to charge. I usually only charge every 4-6 days with about 7 hours screen time. Naturally if you use the tablet several hours worth a day you will have to charge more frequently. The battery is perfectly acceptable, better than the 2012 N7 even though it's smaller.

The 2013 nexus 7 has an incredibly bright screen.... when turned down, it uses very little power, but if you turn it up all the way, it will drain battery like mad. What are you keeping your screen level at? If you keep it in the middle like you say, maybe turn it down a bit. The middle is like max brightness on other devices.... so watch your brightness and you will net much better battery life... also disable any sync/ wifi/bluetooth if you arent currently using them. that will help.
I flashed back to 4.3 to get good battery life again but I did that mainly cause 4.4 and up gave me touch screen issues I didn't have with 4.3

Follow the steps below.
1. Apps like Facebook, Instagram, Mail apps drain more battery even though if you are not using it. So configure them to sync occasionally at 3 hours or more to save your battery. You can also manually turn off sync in the Quick settings & turn On only when you need it.
2. Use apps like Greenify to limit apps like Facebook, Netflix to running on the background.
3. Set your brightness to auto. If you wanna configure your brightness more, use Lux Auto brightness app.
4. Install the following apps to monitor your battery like Battery Stats Plus, Cpu spy, Battery widget & note the values.
5.Also give a few days to analyse battery behaviour & reply if you found changes in the battery.
