What should I expect for battery life? - T-Mobile, Samsung Galaxy SIII

I feel like my battery life is just bad. About 12 hours of use I will get tops 2 hours of screen time, with no gaming. I think it may be that my battery is just defective. My friend's S3 on Verizon gets about 10 hours of use with about 2.5 hours of screen time and is only at around 65 percent and that's with LTE enabled, which should drain the battery more than HSPA+. Mostly I think it's standby that drains my battery. I have looked for rogue apps found nothing. the phone does go into deep sleep, I would say I lose about 2-3 percent per hour, which shouldn't be normal.

Doubtful.

Greatly depends..
If you're on Stock, you're draining will be completely different than on a ROM and it really depends on what you use it for. I am on PA and get about 24 hours with 2 hours of screen time, but some people on the same mod get 34 hours easy but they use it for different stuff.

On screen time

I was wondering what's the most on screen time you guys have had before you phone dies? I feel like after 3 hours ish my phone's pretty much almost dead. How about you guys?
Oh and this is just like browsing on wifi, texting, facebook, not like intense games or anything like that.
Right now I'm at around 4hr 27mins with 20% battery remaining but the highest I have ever been able to have it on for was roughly 6 hours, I do believe. On average though, I get around 5 - 5 1/2 hours screen on time before I need to charge it.
I've been testing out random games for the past 45 mins which caused a quick drop in battery and Words With Friends also didn't help with how much of a battery hog it is. Bleh!

Thanks for answering. Actually got to 4 hours screen on time right now with 18 percent left. Phones been on a total of 20 hours. Does that sound about right to you?

Wow, i get about 2 1/2 hours only! Though i use a ton of 3g data during the day. Overall the battery last longer than it did on my Evo 3D.

Yeah, that sounds about right.
It seems the battery life for this phone is directly proportional to screen-on time. When it's in standby and not connected to 3G, 4G, or wifi; it uses almost no battery. Even when connected to something and in standby, it still barely uses anything.

Yeah, 3G in a low coverage (or almost any coverage) area puts one hell of a damper on battery life, from what I've noticed. I try and keep it off unless I'm using it or needing an app to do background updates or downloads of some sort.

Epic battery life! :D

Ive been trying to get my battery life to 24 hours! i am so close
anyone getting over 24 hours of battery life? share how ya did it!
what kernels are you using? Different Roms? are you over clocked or under-volting?
lets see some screen shots!
There are so many battery threads already out there..

special in that it's less useful because you did not post screen time?
you probably didn't get much past 4 hours screen time if you even got that far so it's not like it's an achievement.
I see very little screen on time. I have done 18 hours stock with 3.5-4 hours screen on but it's on it's last leg at that point. Lol

Why is there so much awake time even though your screen is not on? And unless you got really high screen time, 24 hours isn't that all impressive.

I got 3 hours of streaming music over 3G with 30 minutes of screen time today until i hit 15%.........
Forgot to add, my tbolt with extended battery would take me from NY to Philly using navigation the entire way and streaming music and at the end of 3 hours drive with the screen on I was down to 75%......
It's extremely easy with Juice Defender: Ultimate and the Extended Battery..
GSM, Apex ROM, ORIGINAL 1750mah battery.
1 day 4hours
3hrs 13minutes screen ON time.
I forgot to screen cap the other pic of the huge graph.
This is only on WIFI though during the weekend when I was home all weekend long.
I can't get this high if I was using cell data/wifi during workdays.
Wow. I think I won. I took out the battery and waited 2 days and then I put it back in the phone. I got 2 days and 16 hours out of that.
Try to top that.

Some of us have corporate email, does juice put the device to sleep? I need push email.
I can get 3 days quite easily if im busy and dont get much use out of it.
This state was with about 3 hours screen time.
The main point to take about battery life is that you can make it use all during screen off with Franco kernal and AOKP for example but if your gonna be playing games/watching films the battery will hollow out in no time (notice the 2 big dips on the pic that was while playing GTA3 on full brightness)
So the best you can do is minimise the battery drain when you are not using it. Otherwise its all about screen-on time and a bit to do with how much junk you have running
Setup as detailed in my sig
Another "I get amazing battery life but barely use it" type of thread. Seriously we all know how long the battery can last based on the usage.

I'm on lean kernel and quite frankly, I couldn't tell you the last time I didn't get at least a day. You want better battery life? That is the kernel you want to be using.

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.

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.

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.

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.

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'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.
