Battery life is incredible. Post your results here.

This is with screen on full brightness, moderate use, all sensors, sync enabled, and on mobile data. Leaps and bounds over E4GT.
Edit: battery is at 57% still

What's your screen time?
My battery life actually hasn't been that great, almost equal to my S3 if not worse :/

3hrs 13mins. About 30 minutes of that was using the camera.

Agreed. Mine has blown my E4GT away in battery life, and I haven't even been using the little tricks like turning data off when I'm at work yet.
I normally would have to plug mine in by noon after being unplugged since 7am. And that was screen halfway dimmed and barely any use

I agree. Compared to my 3D, AMAZING. Walked out of work at 6PM, it had just dropped below 60% and my 3D would get to that point by 11:30AM.

I'm consistently getting 5 hours of screen time, which I'm pretty happy with. Haven't ever ran it all the way to zero, so could probably get a little more.

All phones have ****ty battery life when you're hacking and popping bursters everywhere. But my GS4 has done the best so far!
I'm excited to see it. I'll leave my house with a full charge, and streaming radio over 3G to my bluetooth headset for 2 hours and browsing the web for 20 minutes knocks my Evo 3D down to 30%.

How?? I only get 4 hrs of screen on time when I have wifi on, power saving mode on, and have brightness at the bare minimum.. Did you 5 hr screen timers do something else to your device like disable sprint bloatware or something?
Sent from my SPH-L720 using Tapatalk 2
Not doing anything special here. Haven't removed any bloat yet, not using power saving mode, using auto brightness.
Maybe I just have a strong signal. Weak signal can cause the radio to ramp up power and chew up a lot of battery...

This. Turning data off when I'm at work (in a thick building) makes a ton of difference.

Phone gets hot

Have you guys noticed that this phone gets hot fairly quickly during use? Also seems to suck the battery down pretty fast, too. By product of faster processor compare to the Note 2?
Sent from my SAMSUNG-SM-N900A using XDA Premium 4 mobile app
Haven't had any issues. Everything is comparable or better than note 2 with the same usage patterns so far. Going to try some games (like Nova 3) and asphalt to see how it does.

Mine certainly gets pretty warm with regular use. Battery also is not what I was hoping for. I am new to android and the note phones though so am trying to mess around with changing settings and such.

I have a thin case on mine. I notice no heat whatsoever. Also, I've never had better battery life. I use the hell out of it, too. My Note 1 and my Captivate were power hogs, though. That's all I have to compare it to.

Personally, i love the battery life on this phone. Thats coming from an S4. I used to have to put my S4 on the charger before the end of the day because it was in the yellow. Thats from around 740 in the morning til around 6 in the evening. Now, on the same usage, with the Note 3, by around 9 at night the battery is still sitting around 50%.
Wow, any special settings you are using? I am already charging my device today as I was bellow 50% with only a little over 2 hours of screen useage.

There has to be an app running amok, or you are in a bad signal area, or you have every possible setting on to be charging that often unless you have a bad battery. I usually get about 4 hours screen time over 24 hours and usually have 45 to 50% left. Just did 24 hours with 4 hours screen, 2 hours music listening while mowing my yard and downloaded 2.5 GB of data over LTE and had 39% left.

I have a lot of the extra settings turned off. I have power saver on for screen management. Wifi scanning for apps is off. Bluetooth on only when I need. Screen brightness set to auto. Phone is running stock ROM, no rooting. It often feels warm around the camera area. I have been consistently running out of juice by about 12 to 13 hours of use. I don't know....

Pretty much the same settings as mine. I leave GPS on always. Do not use the power saving management features.
Try going into developer options and limiting the number of background activities to 3 or 4 and see if this helps any.

Update. Got mine to 103 F using Skype whilst whilst video talking.
Talking of which the Skype app is ****e compared to IOS version . I couldn't even disable external speaker no option, also when I put the phone to my ear the external speaker is still engaged as is the front facing camera POOH!
No issue here either.....phone is alot faster...battery life is insane....i have never had battery like this with my note 2....i can run for days without charging....great device...highly recommended........you might have a bad unit....you figure they push these out so fast...your bound to get a few duds...i would return for new one.....just my 2 cents.....
I've had no issues with mine but my girlfriend has had a weird charging issue once. In the middle of charging it stopped and said that it was over heating. Thought that was pretty odd seeing as how she wasn't using it at all.

unbearably HOT
Today I was listening to mp3 music off the memory card and noticed the phone got unbearably HOT and battery drain was around 50% in less than 2 hours.
This is normal usage and it should never get warm for playing mp3 music.
I am curious to know how many have a heating issue.
Looks like mine is going to be replaced.
No heat what so ever.... Battery life amazing and that is with pretty much everything on!

There is most likely something running in the background causing this. I listen to mp3s for several hours nonstop off my SD card without any heating issues. Try killing all apps and clearing memory with the task manager then run the music app and see if the heating issue persists.

Well, for the last few days I was not happy with battery life and was getting a lot of warmth on the back as well around the camera. Last night I shutdown the phone totally and rebooted. Had a few updates pop up for some Samsung apps when the phone booted up. Today, battery has been quite stellar. No real warmth either. I am at 70% charge at end of the day with 11 hours on battery and 2 hours screen time. Interested to see if this continues tomorrow. I would recommend shutting down the phone and reboot to see how it goes.

How is your Battery Life? Please put in here

On my first charge so we will see. Please post your battery life stats and pics.
Six and a half hours and it's almost at 50%. I had an iPhone before this phone, and if I used it half as much as I have been using my phone today, it would probably be at around 10-20%. I love the battery life. Screen has been on half brightness, WiFi/Bluetooth off, no battery saving mode on.
Sent from my SAMSUNG-SM-G900A using XDA Premium 4 mobile app
Here is what I have so far. Going to let it get to the power save mode before I charge again (IF that actually happens before I sleep), so I will post again then. This is mostly on LTE, btw, as I've been away from home most of the day.

That's good to hear. I've been using a One M8 practically in place of my 5s all day today and with battery saver on (only decreasing CPU speeds) but Wi-Fi off the entire time (just 4G LTE), I'm only down to 48% after being unplugged for 13.5 hours. Looking forward to what my GS5 will deliver.
Coming from the iPhone 5 (had the 5S, but got damaged so I switched back to the 5 during the waiting period) the battery on the GS5 is incredible. I'm just now doing a full charge cycle, so I'll report back later with some battery results, but I can already tell I will be very happy with this.
I just plugged my phone in so I wasn't able to take a screen cap. I was at 32% battery left with 16 hours on battery with about 4 hours and 2 minutes of screen on use. Most of the day was on LTE, but I did not turn off the wifi radio. All background data options were left on along with location services.
not great..barely got through the day with fairly heavy use. 4 hours screen on time.
Not doing so good. It is the first full charge so I will judge it after it has a day or two to settle in.

Battery getting worse.

I feel like my battery keeps getting worse and worse. Used to last me a day and a half and now only about a day.
Sent from my SAMSUNG-SM-G900A using XDA Free mobile app
Hey mate, sorry to hear you are getting worse battery life. Are you using anything from your normal? Check out my guide and see if anything helps. Below are my stats currently. I can only see you still have your alarm on, this can cause a slight lose.
Mine hasn't ever lasted as long as your day and a half, maybe it is just leveling out? A few days ago I recalibrated my battery, maybe that would help?

Try shutting it off ( hold the off button on right side) the turning it back on . Reboot, I had an unexplained battery issue and this fixed it, I can get 3-4 days now.
Any update @gainstatom?

My battery is either good or bad. Right now it's fine and going good. But sometimes I think something makes my battery worse. I will keep updating with screenshot. I think 8% for only minute on screen time is not that good.

I had a battery problem similar to yours not long ago. One of the things that was running it down was in Settings> Wi-Fi> Always allow scanning. The phone would scan for Wi-Fi signal even when Wi-Fi was turned off. Unchecking that box helped a lot.
I also used a battery calibration app that clears the battery stats and that has pretty well fixed the problem.

Sharp battery drops. Problem with device, rom or battery?

I regularly have scenarios like this.
- phone is at 27% battery
- few minutes later it beeps and shows 14%
- 30 seconds later - 5%
- few more seconds and it shuts down.
I don't run anything special and through the day it lowers steady (although 100 to 27 in 12 hours is not that great).
I run official 5.0.1 rom and never unlocked bootloader.
So is it a problem with a phone, the battery or just OS that sucks?
Anyone else having the issue?

Most likely it's the battery. Have you looked to see what is using the battery in settings?

Nothing unusual running. I think Android OS was main battery user, may be with hour and half of screen time.
In this specific instance I was running Toyota app while driving.
But similar things happened before without those factors. And mostly it worked ok in the car as well.

Sorry I forgot that was in your OP. Did you look at the battery to see if it was hot or bulging even slightly? Personally for the $15 it takes to get a new battery, I would. Worst case scenario is you end up with a spare. I don't know how old your device (and this your battery) is, but it's not uncommon after 9+ months for them to start dying.
Sent from my SM-N910T using Tapatalk
Yes, it probably makes sense to get new battery. I got the phone last November or December but problem started early summer. Seems pretty short time for battery to go bad.
Thank you

It's not unheard of by any stretch. Heat will kill them fast as well. Does the phone ever get hot?
Sent from my SM-N910T using Tapatalk
I haven't noticed it being hotter than other phones I used. Yet I carry it in external pouch so would not always feel it.
It definitely wasn't hot when battery was dropping.
More over, last time I turned it off for 3 hours at 14% and when turned it on, drop just continued and it was 5% in 30 seconds.
Sent from my SM-N910T using XDA Free mobile app
I got not only a new battery but a new phone and have been experiencing a similar problem. Seriously might just jump ship to the N5. Any suggestions on what else to try? I really don't want to shell out $20 for yet another battery if it's not guaranteed to fix anything. I'm running PopRocks v14 with the stock kernel. Any suggestions?
I had the exact same issue. It was from letting the battery die too often. A new battery fixed the issue 100%
Sent from my SM-N910T using XDA Free mobile app
That's true. Running it down to 1% all the time definitely shortens the life. I'll try to find the article I read that interviewed battery scientists.
