How are people getting 4 hours screen on time with stock? I usually end up with about 1 hour screen on, 1-1.5 hours phone call and texting throughout the day in about 15-17 hours. Shouldn't phone calls and texts be using less battery than screen on?

Im using stock lja with deviant kernel just moved to morfic trinity kernel to see a difference.
[T-Mobile, Samsung Galaxy SIII] g2uzer:
Phone calls uses more Battery,
[T-Mobile, Samsung Galaxy SIII] Negativezeroxxxx:
Why is my battery so poor compared to others... Running liquid smooth, gps and sync off at 50% brightness, feel like my screen uses a much higher percentage than nearly everyone else.
[T-Mobile, Samsung Galaxy SIII] crazexr7:
Seems pretty normal to me. But if you want to check if there are any wake locks keeping your phone awake check out betterbatterystats in the play store
[T-Mobile, Samsung Galaxy SIII] aamir123:
Also is everybody who's getting these great numbers using power save mode or can it be acheived without? I'm sorry for all of these questions but I am just trying to understand if I am doing anything wrong or if theres anyway to increase battery life just a little. I seem to make it to about 10-11 pm with the battery about to die however, I need like 20-25% leftover at that time.

Ps. Am I asking for too much?
[T-Mobile, Samsung Galaxy SIII] falcons2:
I don't use powersave. Just wicked v7 with Trinity kernel underclocked to 1284. Ive been averaging about 4-5 hours of screen time with about 14 hours up time. Use better battery stats to see if you have any wake locks using battery.
[T-Mobile, Samsung Galaxy SIII] aamir123:
Well I'm using trinity kernel now was using deviant earlier. Also whats funny is I thought I was using trinity while I was on Deviant. Also You underclocked to 1.2ghz which is what powersaving mode does. So if you run your clock back to stock 1.5 ghz and turn on powersaving you will be in the same setup as you are now. I confirmed this with setcpu.

Does anyone else's battery drop to 98% almost immediately after unplugging from the charger?
[T-Mobile, Samsung Galaxy SIII] elracing21:
Most times. I usually turn off after I hit 100% it usually charges for a few more minutes this way and lasts on 100 longer.

[T-Mobile, Samsung Galaxy SIII] saldebot:
Yep, except for today. Today it took about 25 minutes to get to 99%. Almost had a heart attack cuz I installed CWM touch last night before going to sleep so I thought something happened to the phone, but started draining normally after that.

[T-Mobile, Samsung Galaxy SIII] falcons2:
So far the battery seems pretty good. Topped it off to 100 when it got here then used it a ton the next few hours. I had 5hr 30 mins of uptime with 2hr 15 mins of screen time and still had about 55% left before plugging it in over night

I am getting the best battery life with the stock rom. Last all day easy with moderate to heavy use. Plus I ordered the 2 qcell batteries off amazon so I never run out of battery. Always have one at home charging and carry the other 2 with me.
[T-Mobile, Samsung Galaxy SIII] bbowman:
i was getting pretty crappy battery life (12 hours with moderate use) until I changed my MS Exchange email account from push to 15 minutes. Now my phone will last about 18 hours which is enough for me.

I'd rather keep the email syncing automatically like I did with my old WP7 phone but this will have to do.
[T-Mobile, Samsung Galaxy SIII] g2uzer:
Not sure if I got a bad battery or if this is normal. I'm completely stock, what you think?

Pretty normal. Anything above 3 hours screen time is good in my book.

[T-Mobile, Samsung Galaxy SIII] mt3g:
I average 3.5 hours on screen and about 18 overall.... that or 30 hours with 1.5 screen use. It depends on what day it is and if I'm bored and sitting on my phone or out being social and hardly using my phone.

Here's mine. I had a few issues with the first GS3 I bought, including battery life, so I returned it. The replacement has great battery life, not to mention the other issues I had (wifi disconnecting, buzzing in headphones) are gone.
[T-Mobile, Samsung Galaxy SIII] falcons2:
I didn't think of that. But back on freegs3 and Trinity I would average 4 hours screen time with about 15 hours up time clocked at 1.6. But that was on ics.
[T-Mobile, Samsung Galaxy SIII] aamir123:
Yea I've noticed that trinity is smoother and better on battery at least on my phone. Thats what made me check what kernel I was running and was I surprised to have deviant kernel, not to say that it's a bad kernel. I just want something simple and I feel like stock is the best kernel. But you should clock back to 1.5 and turn on power saving this way if you ever need an extra bit of power you can just turn power saving off instead of messing with settings!

I'm not a power user but my old phone would of needed charged twelve hours ago.
[T-Mobile, Samsung Galaxy SIII] falcons2:
I would but I like keeping my phone under clocked a bit so it saves battery the whole time my phone is running not just when I turn power save on. I've been using liquid smooth rc1 a lot with ktoonsez kernel and get outstanding battery life. Like 16 hours with 5-6 hours of screen time
[T-Mobile, Samsung Galaxy SIII] aamir123:
wow 5-6 hours seems amazing, but isn't liquid smooth an aosp rom? I've been itching to try an aosp on the S3 but twiz has me hooked. Honestly twiz and its features were the main reason I chose the gs3 over the n4.

Any suggestions?

What font is that? O.o
[T-Mobile, Samsung Galaxy SIII] tmjohnsonfse:
What app are you using to set clock? What clock frequencies do you have your phone set at? Have you used CPUSpy or similar to see if your phone is going into deep sleep when idle. I've been testing my phone the last couple of days for standby battery life and I'm using about 1/2 to 1% per hour battery loss. That includes the occasional text and email reply. That was through 70% of battery life, plus I verified to make sure it was accurate. I'm using clock speeds of 1512/394. For your screen on time there are a lot of factors. Brightness, talking on phone, game playing all will kill battery at different rates. 3 1/2 - 4 hours on time from the posts I've read doesn't seem all that bad. But, 10% when not in use seems high based on my results.
[T-Mobile, Samsung Galaxy SIII] EtherealRemnant:
I've used the stock kernel, Deviant kernel, and Xone kernel. Deviant had the worst battery life (but a max 1944MHz clock speed) followed by stock which is followed by Xone. Xone runs at like 1.6 and doesn't really seem to impact battery life much. My battery could be bad. I have a second one since I called T-Mobile about the battery life but figured that it was just par for the course with the S3 until I started seeing the figures on here.

I can't check my settings right now because I've turned my GS3 into a development platform for Ubuntu Touch for the time being but I believe I had it at 192 min/1600 max using smartassv2 and sio?

Dear lord, what are all your clock settings?/Brightness, governor and i/o, sync on/off, etc. I'm running liquid RC2 with the stock kernel and am only getting about 2.5-3 hours screen time...

I went back to rc1 because rc2 didn't run as good on my phone. Those insane battery times are from using the 2/8 version of ktoonsez with rc1. I'm currently testing out the latest build of ktoonsez right now

Not sure how you managed to get such insane life, here's my first cycle results using liquid RC1, ktoonservative and row i/o and under clocked to 1134, what's the point of a governor that scales if all it runs in really is the max/min?
[T-Mobile, Samsung Galaxy SIII] falcons2:
Its only the first cycle. It will get better. I forgot to take a screen shot last night but I got 14 hrs with 4 hrs 30 mins of screen time and still had 23% left. And that was with an hour of listening to music
[T-Mobile, Samsung Galaxy SIII] EtherealRemnant:
I highly recommend that you use the Ktoon kernel if you want stability and amazing battery life. I am going to run it down and post my GSAM. I heavily undervolted the chip. We are talking 1050mv at 1512. And the way its working, it seems it might go lower. Dropped my temps too!

3.5 hrs is what I get as well.
[T-Mobile, Samsung Galaxy SIII] EtherealRemnant:
This is what I got under heavy browsing, WiFi on, watched the hour and a half YouTube launch event for S4, auto brightness.

Wicked v8 with a highly undervolted ktoonsez kernel on ktoonservative 96/1512 with 384 max screen off. I have to figure out what is draining it so fast in sleep. Either way, this is the highest I've ever seen. Not just on this device but any Qualcomm device... I usually get 3 to 3 1/2 onscreen.

I still have a lot of tweaking to do but considering I usually get a lot less with brightness locked on the lowest setting (no auto), I don't think it will get much better.

Also, I am testing out the Qualcomm Battery Guru app which I think actually makes my battery life worse so I'm going to freeze it and run another cycle and repost.

To give you guys an idea how much I have undervolted, my voltage is only 1050mv at 1512 and 850 from 384 down. I don't think most 8960s will go that low so if you mess with it, don't set it to load on boot.

Happy tweaking!

This is a myth. A Google engineer came out a while back and explained that wiping battery stats does nothing for battery life. Which is what this app essentially does.
[T-Mobile, Samsung Galaxy SIII] ZDeuce2:
I was under the understanding that you are always supposed to wipe battery stats after a rom switch, due to that fact that kernels all have slight differences. And google doesn't want you to mod your phone anyway... so they wouldn't see a need to wipe battery stats. I always seem to get better battery life after a wipe anyway, but to each his own. I'll continues to use it. If y'all don't want to, fine by me.

It's been proven that it does absolutely nothing. I'm not telling you what to do, you can wipe away. I'm just saying that there's no argument about whether it helps or not. It just doesn't.

Although that will take a little more time since they usually need time to settle.
[T-Mobile, Samsung Galaxy SIII] ZDeuce2:
I stand corrected, it ,according to many, doesn't help battery life, it does, improve the reporting accuracy of the battery to the system, so while it may not help battery "life", it does do something, according to google engineers.

Oh, also, Google's official stance on rooting and modding your phone is that they have no stance... meaning, while it is open source, and anyone can contribute, they feel that custom roms open you to huge security risks, and deny Support of many of their apps tun rooted users. Wallet, movies ect.

[T-Mobile, Samsung Galaxy SIII] EtherealRemnant:
Sort of off topic but since its been derailed anyway, is there a battery that fits the stock case (I love my Incipio case and refuse to give it up) that exchanges NFC for extra battery life? Its been really hard coming from a MAXX and getting 30+ hours of battery life - even my Captivate got better battery life than my S III does (and that was stock, not rooted).

I honestly think I have a defective S III because it will lose 15-20% in 8 hours of standby with -90dBm and wifi, GPS, and Bluetooth off... Something doesn't seem right about that...

What are you running? Rom, kernel? And have you checked your wakelocks for drain?

Sent from my Infamous powered Galaxy SIII
[T-Mobile, Samsung Galaxy SIII] EtherealRemnant:
I was running Wicked v8 with ktoonservative with serious undervolt (we're talking 1500 being 1000mV) and still wasn't gettin it... I *THINK* I was using noop but its gone now so I can't tell you for sure. I saw some posts about ktservative and row... never tried that but I don't think it would make a huge diff. I was either noop or zen. I just am not remembering.

I just moved over to Hellybean and we'll see how it does... I can already tell you that the kernel doesn't heat the battery (biggest problem with LiIon is heat - completely opposite of LiPo which ... those bastards got hot... You *HAVE* to have a case unless you want to get burned if you have a MAXX... GSAM said 110 on average.

As for wake locks... I've looked and haven't found any rogue apps but maybe you can tell me something I'm missing. GSAM said I had wakelocks but they were all from the kernel. If you have an app that can read further than that, I'm all ears.

I KNOW this thing is supposed to be 2-3 on standby and I can't even get through 24 hours with NO use. It dies. Two different batteries. *sigh* I have the equipment protection and T-Mo said they would be more than happy to send me a refurb... but even the rep I was talking to confirmed my concerns that the new one would be worse than the old one and that if I had issues with the replacement, it wouldn't be easy to get a second replacement. Meaning... they would ship me a device and let me keep mine but once I got it, I would HAVE to send the other one back. Unless I wanted to go through the headaches of explaining that I sent back the one they sent me because of "X" issue...

Basically, I just flashed Hellybean... and I'm gonna see how that works. I wasn't overclocking either so ktoonz could have been causing issues. Since our device is an official CM 10.1 device, maybe this kernel will just work better.

I will tell you though, and I know that's for another thread, but I miss the Samsung app killer on any AOSP/AOKP/CM ROM. It comes in handy.
[T-Mobile, Samsung Galaxy SIII] ZDeuce2:
Better battery stats is a good app as far as being able to check out what your battery is doing and the drain causing it, it does cost around 3 bucks on the app store, but it may just ad worth it to you

For around 3 bucks on app store, better battery stats may be worth it to try and fine your problem. It is very comprehensive, and has helped me out in the past.

Other than that I can't really compare what I'm running. Been running infamous 4.x now for a while, with the kernel in it, and have had plenty of life.

So far Hellybean is performing very well, the phone doesn't get hot at all, and the battery life is much better. Plus the GPS locks on indoors now, something it never did when I was running ktoon's kernel.

I haven't tweaked it at all as of yet... one thing that I found that was draining the hell out of my battery - NFC was on and I didn't know it...

As for the battery app, unfortunately I can't even afford 3 dollars at the moment, that's how broke I am. I will keep it in mind though - I love GSAM.
