Post your battery life

I don't see a thread like this for the T-mobile variant so I figured we can have our own. It would be nice if you included the following with your posts:
screenshots including on screen time, information about your rom, kernel, etc. and estimated talk, text, browsing, and gaming time, and what brightness you had your screen on (auto, full, etc.). If you use something like SetCpu with profiles list your profiles and settings here too.
I'll start:
This is only my second cycle charge on this device. I only got it 2 days ago now which means it still has room for improvement
My sig has my rom info and I basically did a lot of twitter browsing, about 100 texts a few short minute phone calls including an hour long call when it was at around 10%, a lot of XDA reading, and no gaming today.
I have the device overclocked to 1.89ghz with this kernel with min set at 384mhz ondemand governor. I have a profile that clocks down to 1.5ghz at 50% battery life and another that clocks down to 1ghz at less than 10%.
I've never had a device give me 4h on screen time especially with the abuse I give this device. I can't wait to try out other kernels and roms to see these numbers rise.

I could get a day and a half with no tweaking and low usage, on an average day I'm getting ~15 hours before it starts whining about the battery

Yeah but what's your on screen time?

Right?! That's what it comes down to. It doesn't matter if your battery life is amazing if the reason why is because you barely if ever use your phone...

I'll post tonight just got my new anker battery.

Considering your screen was barely on during those 18 hours I can see you didn't use the device much. This is barely average.

This is first charge on anker 2200 mAh testing them out. Will report what stock gives me. I had WiFi on from about 95% to about 50ish.

Worked 12 hrs that day. But yea, it was idle quite a while.

This what i get

Throwing bricks since 2008.....and proud of it.

I could make it 24 hours easily with light usage. With moderate to heavy usage, probably around 20 hours. It really depends on how long the screen is on though. This phone has amazing battery life. My HTC Amaze probably only lasted half as long.

I agree, best battery life I have had out of all of my previous smartphones. I am still testing roms and kernel combinations to figure out what works best for how I use my device. I'm in the middle of testing FSG3 rom with trinity kernel. Will post up battery usage within the next 2 days to compare to my previous Stock rom with Adama 003 kernel battery life.

My Screen
Pretty Good so far, Stock Rom - Rooted - Still 40% left.

This is with the fsg3 rom and trinity kernel. First and only cycle so far. Brightness 100% wifi on most of the time, and data and gps always on. Played music for about half an hour and browsed xda for half an hour.
Edit: screen on time was just over 4 hours deleted the ss by accident.
Will post up the 2nd cycle when it's done.

New screen shots after a few cycles. Again fsg3 rom with trinity alpha 36 kernel. Brightness 100% wifi on most of the time, and and auto sync also on.
Look at screen time on not just total battery time. This is what determines good battery life not letting your device sleep on your desk for 2 days and saying you get amazing battery life.

Battery life expectations?

I just got my s3 a couple days ago and am just wondering what I should expect for battery life from a stock, unrooted phone? I keep auto bright on, keep wifi on, and only have google mail auto syncing. In 2.5 hours it is at 92% with 15 mins of screen on time. I've never had a Samsung before, my last phone was a sensation so I can't really compare the two. Is this pretty standard and would rooting and a custom rom make much difference?

I used to get 10 hours with very heavy usage I'm on frosty jb v3 now I get up to 14-17 hours moderate use. Not sure for everyone else but my battery life has been amazing with this phone.
Make sure u have power saver on
Sent from my SGH-T999 using xda app-developers app

Thanks, I noticed the power saver setting but haven't tried it yet. It doesn't slow the phone down too much?

With heavy use I usually get around 12 hours with over 3 hours of screen time. I'm running freegs3 with the newest Trinity kernel and no powersaving options on
Sent from my SGH-T999 using xda app-developers app

It depends on what your usage is, if you game alot and stream alot I have seen some people get between 8-12 and with moderate usage I have seen between 12-15 hours and with minimal usage I have seen some go over 24 hours.

Is my battery life normal?

Hi All I just got the Galaxy Note 2 like a month ago and I've been loving it the only thing that I've been question mean if the battery life right now I'm getting like 4 hours of screen time and that's basically what I use to get with my Galaxy Nexus.
I just wonder if this is normal because I hear people a lot saying that they get several days of battery in for me I just feel like I have to charge it every day I also been monitoring the apps that I have and the background usage of them and nothing seems to be draining it.
I'm using android HD 6.0 with Perseus kernel

On really heavy use, that is pretty normal. But for normal use or moderate ones, certainly not. Based on your screenshots, you have a lot of wakelocks, these are the number 1 culprits for unexpected battery drain, go get better battery stats and use the phone exactly as how you used it when you took those screenshots, then after a day or two, checkout better battery stats and find which app was actually causing those wakelocks.

[Q] kernel for best battery?

Hello all I was wondering if anyone had any suggestions on which kernel helps save the most battery. I am a high school student and by the time I get out at 2:15 my batter is at like 30 or 40 percent (even know I don't get that good of service and shouldn't be using my phone In school anyway lol) but im using the infamous 3.9.2 rom... Any suggestions would be great!
Sent from my SGH-T999 using xda premium

Well to be honest no kernel is gong to be the "best" is more like you need to be conscious what you have on. You have to give more info like what percentage you have brightness on, how often you have data on or gps. Also syncing takes battery away so having those on will take big chunks. Really battery shouldn't be that bad because technically I would guess your not using it as much in school.

I normally have the brightness the lowest it can go. I never have gps on.. I use juice defender to turn off my data when I'm in rooms that get no 4G and im assuming synching is off when my data is off to.

What's your typical usage - the screen on time ?
If it's average use and nothing is wrong, you might want to consider buying either an extra battery or an external battery to charge with. Or an extended battery. Battery battery battery.

Sent from my SGH-T999 using xda premium

use one of the several methods to find out what is using the battery...i use betterbatterystats then i find out whats waking my cpu and go from there...
after that i use titanium to freeze the problem...I do this for several phones and normally can get way better battery life from them

Just make sure you don't freeze something important that's going to cause problems. If it's a app you can always uninstall..I'd your screen time is about 4 to to 6 hours expect like 9 to 10 hours max of battery life. Extended battery will make the phone look bulkier and having a case is a issue. If anything get an external battery possibly with charger too.

Try Lean Kernel its the best for battery life.

Battery life.

I've got to say, battery life is pretty bad with this phone. I bought it brand new yesterday so not sure if it needs to condition itself or not but I came from a LG G2 which has a 3000mah battery, which is slightly smaller than this but battery life was far better. Granted the screen was slightly smaller but still. Is there any Roms that improve battery life but still relatively stock?

Have you disabled all the smart scroll and air gesture stuff? Its useless and hogs battery life. Auto brightness and juicedefender and I can rock it for 2 or 3 days straight.

How long is it lasting for you?
Sent from my SM-N900T using Tapatalk 2

Ya, this sounds bizarre.. I've found this battery to be amazing. How long is it lasting? I've had mine for less than a week and I've used it heavily everyday. I have not even had to worry about charging during the day. 24 hours no problem.

Same here. The first week it was lasting all day but with only 3 hours of screen on time. After some tweaking, I'm currently getting still 20ish hours with 5-6 hours screen on time.
Sent from my SM-N900T using Tapatalk 2

I just don't get it. A lady I know has the sprint variant and I looked at her settings and she had 15 and a half hours off the charger with 5.5 hours screen on and had gps and all the air features on as she's not tech smart so her phone was like out of the box and her brightness was up. I have a custom ROM with GPS, NFC and all the air gesture **** off with the screen at like 35% brightness and I get no where near that.

Also what tweaks did you make? I should rephrase that I get good battery life with the screen off, it lasts all day but screen on time is horrible.
In this pics android os and google play services is destroying battery. The screen time was only like 1 hour and 15 minutes at that time.

I downloaded that we'll see how it works. Like I said the battery easily last 24 hours with medium to little use but it dies fast while using the screen on, I'm seeing others with everything on like GPS, NFC and al the touchwiz things with their brightness up getting far better on screen time than me with everything off and brightness dimmed

Any suggestions appreciated. Anyone try an extended battery yet ?

Stock rooted, I was getting about 24 hours per charge with about 6-8 hours of screen time.
I just recently installed Faux123's kernel and enabled the Intelliplug and Intellithermal drivers, now I'm getting about 60 hours per charge.

Well my actual battery just must not of been created equal with other phones because after tweaks I'm getting better battery life but only about 5 hours screen time and I have everything turned off with screen on 35% so I don't know :/. I'll check that kernel out.

Well if that is the case your battery life isn't terrible. 24h with 5h SOT and 24% life isn't bad at all. Its not great but it is far from terrible.

I'm just using the stock ROM, rooted with the Kingo Root app. Installed TWRP and then Faux Kernel (hltetmo-faux123-003u)
Be warned, TWRP did trip the Knox counter to 0x1. I had to install Knox Disabler so it would stop complaining.
I was getting about 24 hours per charge, until remembered about the FauxClock app and enabled the Intelliplug driver and Intellithermal manager. About this time, I also installed Advanced Task Killer after going without it for a few years.
Screen brightness is on auto, WiFi and mobile data are both on constantly. I have not had to make many calls though, so I'm not sure how this may affect battery life...
So far, I haven't noticed any decrease in performance. Right now I've been on battery for 30 hours and I have 45% left.

Because of adjustments... Custom ROM and kernel, Screen is at 35%, gps and all location services off, NFC off, all the phones extras like air gestures multi window etc are off, I use greenify to freeze apps and I have most Google syncs off and I'm only able to achieve this. I know a lady who knows nothing about phones and has everything/feature on the phone turned on with full brightness and gets 15.5 off charge with 5.5 screen on time by the time she's at 30%. I don't get it.
Edit- I should note I made this post while stock. Because I heard phenomenal things about this phones battery and was quite disappointed.

Signal strength and the binning of your CPU could be differentiating factor. Reading into other people's experience too much can lead to disappointment.
