CDMA/LTE or GSM?

Im with sprint so cdma/lte. sorry lol

Franco Kernel is generally pretty good. You can also try CM9 for a stock ish rom.

do you have the extended battery? how long are you getting currently/how much screen time?

CM9 nightlies with either the kernel it comes with or trinity, (for extra features and performance). With that setup I get superb battery life!

I have the Verizon Galaxy Nexus, and I've tried pretty much every combination of roms and kernels. I've had good luck with Lean, Jame Bond, and Franco's kernels. As far as roms AOKP, Liquid Smooth, and Slim ICS are great. Right now I'm on Slim ICS 3.9 using the kernel that came with it, and my phone LOVES it. I just checked and I have 30% left of battery, it's been on for 12h 44m, and the screen has been on for 2h 44m. That's wifi with a little 3g thrown in, and mostly web browsing. YMMV though, as all phones are not created equal.

make sure to turn off LTE if you don't have it in your area

Doesn't make a difference. It only drains battery if there is poor LTE signal. Not if there is none.

I'm not questioning your response because I really don't know, but wouldn't it be reasonable to select cdma only if there is no 4g in your area. Doesn't the phone "look" for 4g signal and if there isn't any, wouldn't that cause a VERY slight battery drop?
But like I said, I don't know.

I believe, and don't quote me on this, that it communicates with the towers of course to determine if there is even an LTS signal to look for. That way if the tower responds as there isn't, it won't search.
I probably just made that up but if you don't have LTE your battery won't be effected by "looking" for it

That's when you get a different battery because you clearly have a hardware problem.

I agree , CM9+trinity=Best combo for battery life
CM9 kang powered by TRINITY

Something that I noticed helps is turning of Location Service. I mean, this icon that you have between Bluetooth and Sync (on Stock Rom 4.0.4). This turns off the GPS and I've noticed it made a noticeable difference. Can't precise exactly how much, but it's a lot better for sure. If you guys could try and give your feedback about it, it would be nice.

Rooted Galaxy S3, Now what?

OK, I just rooted my Sprint Galaxy S3 today so now I have a question.
I want to also see what i can do to extend the battery life. Any suggestions?
My main reason for wanting to root was so I could tether it with my new ASUS Transformer Infinity. I've got that worked out and it's great.

Have a look in the roms section. Many of these roms will increase battery life. I'm using Blazer and I'm quite happy with it. Though I'm looking to get into jellybean soon. Flash at your own risk! Though if you got through rooting I'm sure you will be fine .
Other things you can do is switch off anything you arent using. GPS, BT also have a look in accounts and sync in your phones settings. Don't sync anything you don't want synced. Anyways thats all I usually do.

If I am not using them I toggle GPS and WIFI off, that helps me extend battery life. As previously posted check out some ROMs I'm particularly found of clark44's FreeGS3, for me it provides the best battery life so far

OK, I'm a total newb to all this rooting & flashing ROM stuff. Yesterday's S3 and the TF700 was my very first time ever.
Question about the different ROMs - Do you lose any functionality like WiFi or anything else when flashing these different ROM's?
If so, I'll just live with what I have.
Thks for the help~

Just start looking through them. Usually in the OP you will find all the information about what is different, what works and what doesn't

Going with the most popular roms you should be fine, everything should work and you might even find that your phone is faster. Roms like Blazer or FreeGS3 are a good place to start imo.

[Q] Which JB ROM works with PDroid?

I'm a NOOB when it comes to Android development, so, when I try to run the "Autopatcher" and it fails then it's time for me to give up and ask for help...
Has anybody gotten PDroid to work on Galaxy S3 w/a JB ROM?
If not, I guess I'll have to see if I can figure out how to fix the errors. Need to learn how to make a COMPLETE backup of my phone first so I don't have to re-install apps next time I soft-brick/boot loop my phone - need my phone to run solid as my "Daily Driver" (don't have a second GS3 for testing purposes...)

I'm assuming you're using cm10 or aosp?
I'm not aware of anyone ever getting it to work on non-aosp roms since the original was written for GB. Unless there's been a breakthrough in the last month or so, I wouldn't expect to see it on TW anytime soon.
Hope I'm wrong though! I've wanted this for a long time! But if no one could get it on ICS, well, JB is a bit more....finicky....

Well I was on Liquid Smooth and that was good, but, I missed some of the Touch Wiz "enhancements" - but - most of all I read this statement regarding any non-TW ROMs: "are missing the Qualcom Optimizations which" which make a substantial difference in performance.
AFAIK none of the CM10/AOSP ROMs have those optimizations - greater efficiency = greater battery life.
So I recently switched to FreeGS3 R7.1 "Resurrection" and when I look at my Battery and see that I've been on for 22 hours with SIXTY percent left - WOW, I don't want to go back.
But every day, several times a day, I'm thinking to myself how much it SUCKS that I can't control app permissions on my own stinking phone! ARGH!!! I miss being a teenager without the combination of work/school/kids/wife that has a list of things for me to do 'cause I don't have time to spend hours every day on software development for my phone (I must admit though, I do sneak into these forums whenever work is not busy, so maybe I could do some but I hardly know where to start in terms of getting PDroid working...)
I've asked several places, but don't know yet - is there ANY stable Jelly Bean ROM that works with PDroid for T-Mobile (T999) Galaxy S3?
EDIT: I feel like choosing between "Qualcom Optimizations" and PDroid (not being able to have both) on Jelly Bean is like buying a car and having to choose from either not having the engine, or not having the wheels - ie: not a good choice to have to make.

OK, my friend at work finally found one for me: galaxymod (port from Verizon).
Here's the link: http://forum.xda-developers.com/showthread.php?t=2089801
I'm still looking to see if SynergyROM has been ported?

Jelly Thunder

Just wanted to post a huge thanks on the jelly thunder port. I flashed this morning and have not had any issues that I can recall, or any FC's. Im on Telus, and LTE is working perfect. GPS is also working excellent, it took a little while longer to fix its position initially but it has been great since. I hate cluttering up the dev section. So for anyone wondering about the Jelly Thunder. So far its perfect. Excellent Port.

+1 on this..... This is the smoothest rom I have used to date, the eye candy makes it all the more better. :good: :good:

I agree with you all. The eye candy does make it even nicer that's for sure. The only thing else I would like to see is the stock samsung keyboard or at least get the symbols back.

Wait till this theme im making for this rom is finished..muhahaha

+1...I've been flashing a bunch...and this one works perfect.
Follow the directions...and Let the Thunder roll
Mac

Wish it had the stock icons

Love the rom. Great work. Im having issues with 4glte. At work I always have 4g lte speeds but with this rom it swiches from 3g to HSPA+ and 4G (When I have 4G it does to to lte speeds).
Is there a setting i can change?

As far as I remember reading it does the switch to conserve battery power. I live in a city and I get lte at work, but not at home. I don't think all towers support lte

Im also running this...flashed last night,looks and runs great!
Im also not getting the lte speeds when I have lte.

Ohhhh weeee! I have only seen awsomeness and giggles when you tinker Wish777. Well except that time the phone became self aware and stalked you for a month. Still awsome! lol

Personally I think Jelly Thunder is the most stable - smoothest - Most complete and themed - simply the best ROM that Note 2 has had to date. In my opinion anyway - I have not seen or used a better rom since I got this phone - and I purchased it on Day 1 of the official release at ATT.
I personally like the ICONS - and as for SPEED - my LTE speeds are just as good with this ROM as they been with any other I have used. I flashed the Note2Core EX kernel - and it seems totally complete. Fast and smooth - Antutu benchmark scores consisttently around 195000. simply awesome.

H+ showing instead of LTE
I just flashed the JellyThunder Blackout rom to my Galaxy Note 2(i317 AT&T). Now it appears that I am getting H+ speeds instead of the LTE speeds I was getting 10 minutes ago before I flashed this rom. Does anyone have a solution to this? It will be much appreciated.

[Q] Wholly Bleeding Battery Batman!

Hi!! I was just wondering which ROM has the best battery calibration so the battery will last longer! I know it is a powerful phone so it is expected to drain faster! Just need a good suggestion for the best ROM that will address this issue. ThAnKs!

This is a hard question to answer because battery life is very different from phone to phone but from what I've seen stock based roms like lifeless usually give the best battery life.

On Lifeless I was able to get full day usage regularly... CM10.2 8/20 build is also giving me good battery life
Sent from my LG-LS970 using xda app-developers app

I had good luck with Lifeless, but am really enjoying CM 10.2
I have underclocked to 1134 and my battery is quite good all things considered. I play Ingress for about 2 hours a day at full brightness with WiFi scanning constantly, and I have to recharge after about an hour of that. But everybody that plays Ingress knows how big a drain it is on battery. When I don't play, the battery is good for 10 hours + for me.

Better make sure you get the invite in order to play. It is, hands down... the... best... game... I have ever played on a mobile phone.

Ingress looks really fun and I started playing recently, but I don't have a plan with a carrier (I'm waiting for FreedomPop to come out). It's so hard to play on only wifi!

Where did you download the CM ROM? I looked on their site but the only model LGOG they list is the GSM model (Verizon, AT&T) and not the Sprint model. I loved the CM mod on my previous phones and wouldn't mind giving it a try on LGOG. Thanks in advanced for your help.
EDIT: NVM. I think I found it. I take it your using the "Unofficial" CM ROM which was ported over to the LS970? Had to do some digging over at the dev side but found the thread.

Installed the Unofficial CM 10.2 ROM latest version as of yesterday) and it works pretty damn good. Although battery life seems to be a little weak. But then again, I ran Eco Mode on the Stock ROM. Still, my phone sits in a security locker all day at work and not really being used and as of this moment (3PM EST) battery is at 61%. Whereas on Stock with Eco Mode it would be around +85%.
Not sure what is considered standard battery drain not using Eco Mode. However, that will drop sharply in an hour and a half when I get off work and start actively using it again. I'll be interested in seeing how long it will last. Normally I can go the rest of the evening up until bed time on Stock ROM without having to plug it back in until I go to bed. Somehow I don't think it's going to make it that far while running on the CM ROM.
