Better battery life out of an extended battery?????

I have an extended battery (2600). I was wondering, what does everyone do to get the most out of their extended battery if you have one? I'm hoping to get tips and or tricks from my fellow EVO users. If you have nothing positive to say, please don't post.. Any help is appreciated.

Are you rooted?
I use the stock battery on my rooted Evo and it lasts all day.

It really does depend on weather your rooted or not cuz on my stock battery I can go about a day in a half maybe a couple hours less MAYBE but then I have a Seidio 3500 mAh that can go exactly 2 days 1 hour and 38 minutes with heavy heavy use and also on a charge of 93 percent
So again are you rooted?

http://forum.xda-developers.com/showthread.php?t=712990 check that thread, ever since i followed the steps my battery life is so much better. its been off the charger since midnight and i browsed fb for like 30 minutes, texted my wife n browsed the market for a bit and its only down to 89%. btw im using the stock battery.

Not really lol I think that's pretty good I'm guessing that you got that with moderate/heavy use?
You may wanna give another ROM a shot and see cuz battery life may very between them. As well as kernels.

Will give that one a go. I dled it a few days ago but i accidentally deactivated my EVO lol luckily i unrooted it and got it back to root just now so im going to give that one a go

Any stock kernel will not charge any extended battert correctly. I experimented with this for the last month.
I found an app called boot manager and now have 4 roms installed on my phone. At night I boot into a Froyo ROM with a SBC kernel and charge it, then in the am, boot into my Gingerbread ROM.

Yep. If I don't use my phone it will last all day and lose about 1.5% every two hours. I just recently switched to my current setup and am still not used to it. I'll unplug my phone at ~95% and head out the door. I'll pull it out of my pocket a number of hours later and see that it's only down to about 93% - 92%. Before I switched my setup I would've been down the low 80's if not lower. When I use it my battery depends on what I am doing with it and what I have my scaling set to. Using my phone for things like texting, facebook, email, and some web browsing on Skyfire, which is what I would consider heavy use, it goes down about 3.5% per hour. Yesterday I went to my little niece's dance class and I used my phone to record video of her entire 60 minute dance class. Battery went down about 30% percent from that but that's to be expected. I remained out of the house for another 8 hours after her class and my phone still had 50% battery left by the time I got home. Wireless tether eats up my battery. But Thats because I am usually tethering while texting and testing launchers and such on my phone.
I do all of this on a stock battery. So I can only imagine how much I'd be able to do with an extended battery.

I get 30+ hours on my extended battery 2600 from sprint. LOL on warm 2.2

No oc or uving, this is complete stock KL1 kernel they way it came with the phone. I actually had great battery life (about 17 hours) on stock, but I switched to other custom kernels and didnt have so great battery life. So, I was looking for a stock kernel and in the end made this one and flashed today. So battery life should be like stock.

Quick Q, I can ODIN this over Juggernaut 4.1? Without a wipe/reset?

Thanks. I am getting ****ty battery life also. I have tried everything, faux's, bullet, synergy's different versions, Gideon's UV scripts, underclocking, undervolting, with complete wipe, different roms, you name it. I still I lose 20+% battery per hour while I read on my phone. 10-11% if its idle. Completely ridiculous. Just tonight I thought of trying the stock kernel. Plus anytime my phone is awake, the top portion of my phone gets hot. I'm hoping its a kernel issue.

That sounds really bad. I was getting horrible battery life on other kernels but not that bad (i got around an average of 7-8 hours on custom kernels). However, one thing about stock kernel is that once you flash it, you have to give it 2-3 days -sometimes more- to get full capacity battery life (around 17 hours heavy use for me).

I'll test it out. My only concern was that the phone would warm up for no reason. The only time my phone can save battery is in flight mode. 7 hours in flight mode take about 5-8% battery. So the issue is most likely radio/kernel related IMO. Even having sync/data off didn't help much. I also average 7-8 hours. It's just that when I have the phone on to a dark screen with white text on it (opera mini, it has no fancy stuff, good reader browser) I would lose at least 15% in about 45 minutes. This is with no music, no data activity at the lowest brightness setting.

So this is my battery life after the first day. I would say today was lots of heavy use for me. Usually around this time im charging from dead, but with this kernel I still have 30 percent left to go. So about 15-16 hours on one charge with heavy use .I've tried all the custom kernels and this is the best I've ever gotten....

This one helped lots. I unplugged my phone at 1AM (100% charged) and then put it in flight mode. At 7AM I turned off flight mode and had used up 1% in 6 hours. From then till 3:30 I went down to 50%.

shehrammajid,
Thanks for the stock kernel. I am also trying to learn how to build a stock kernel. I have made a post here: http://forum.xda-developers.com/showthread.php?p=22845175
Can you please take a look at my steps and see where I am going wrong? Also can you post the guide you followed by bubby323?
Thanks.

Horrible Battery Life for me

My phone has TERRIBLE battery life. In about one hour (on stanby with wifi or data on) my phone loses 10% battery without use.. Which is a 10 hour battery on stanby. I can BARELY make it through one day without my phone dying either. By the time i get home from school, my phone is down from 100% to 65-70% with VERY minimal usage. Then by 9:30pm my battery is down to 20% with moderate usage on wifi. I am running Beastmod 4.2 REMASTERED with whatever Kernal comes with it.. I have tried Juggernaut, Beastmod, Beastmod Remastered, Stock, unrooted, domination with no luck. Ive tried underclocking, over clocking, changing settings, brightness, different launchers and so forth. Still, i have no luck. Yes, i have calibrated my battery, and this is my second phone from T-Mobile (and 3rd battery) that has a short battery life. Can someone PLEASE help me with this. Thanks!
EDIT: Just typing this message i have lost 3% of my battery on wifi...

I really dont know what the general view on this is....but if you are flashing a lot you wont know the difference. You need to get through atleast a few full cycles to figure out if something has decent battery life. No ones phone is going to put out the same results. I have had a lot of bad results with ROMs people claim to be the best. Just try a rom + kernal combo, give it a week, see if things start improving, else flash something new the next weekend. Do proper wipes, restart your phone when its charged at 100% and go from there.

You leave GPS on? GPS is a drain even if you're not actively using it. Also try charging the phone to 100%, then drain the battery completely, then charge it back up to 100% with the phone off. I've found that usually greatly improves battery life.

Do a full wipe and flash macnut r1. I had similar problem as you until i flashed this rom, i think his kernel has the best batt life of them all and most stable for me. Worth a try

Check Battery info. Is your phone awake even when the screen is off?

I leave it on lionheart governer with max 1,512 and min 192 and it works very well for me

Try this wipe your rom clean and dont install any apps just your emails and try it for a whole day maybe an app is eating your battery in the background.

Click the graph.
There should be a "Screen on" section and an "Awake" section. The two should be pretty similar. If you see a lot of Awake time even though the screen isn't on, it means you have a wakelock.

Blazer ROM - Running Hot???

Hi guys,
Rooted my GS3 today and flashed the Blazer ROM. I've read that sometimes it takes people a few days before this ROM runs smooth...
Seems to be draining battery quicker than my stock root, and it has occasionally been running extremely hot.
Should I be concerned or should I just let it play out for a few days?

I think this phone just runs hot in general. I know mine did - both on stock and on a custom ROM.

Stock didn't seem to run hot for me. Seems to be OK unless I'm using 3G. That's when I seem to notice a drastic increase in the phone temps...

Also my phone has been off the charger for 7 hours, and under light use the battery is at 42% - which also seems low to me...
Thoughts guys?

Try to reflash the rom, and let it settle for 2-3 days and see if you get better results.

*sigh* i just got all my apps/widgets where i wanted them...
do i need to rewipe everything?

Well hello there sir, I am sorry to hear about your overheating/heating up problem and I can assure you, it is somewhat normal. Depending on how hot the phone is really getting.
I wish you had given us/me more information to help better assist your question and maybe solve it for you.
Download battery solo widget, which comes with a widget to install on your home screen, once you have installed it, press it and it will tell you the temperature of your current phone.
I will say, I did just get my Galaxy S3 about five days ago, and Rooted it two days ago. Same exact Rom also, blazin fast.
I will tell you, I installed Battery Solo Widget and my phone with use usually stays around 94 degrees with the house being 70 degrees.
My old OG EVO 4G heated up to 102.65 then shut off. I haven't gotten my S3 past 95 which is totally normal.
To be on the safe side, PLEASE re-install your current Rom, remember to backup your current Rom/SetUp, remember to factory reset/clear cache & dalvik cache then flash the Rom again. I let the phone sit for about 15 or so minutes after flashing before I turn on the screen and set the phone up.
Please let me know how hot your phone is really getting and maybe its not a concern.
Please let us know how the outcome comes along, I am curious and here to help. Thank you!

The only way I make my phone hot is by using Wave, app for GPS and live reports. I know is the app. Is the only way I could make my phone think I guess. Between the 3g and gps that app seems to drain and make this an Oven..

Give it about a day or 2 and the battery should be good. About the overheating, for whatever the s3 runs a bit hotter than other phones.

I'm at 77%. Took it off the charger at 6:58a.m. and it's 10: 29p.m. That is with light use. Let's say around 20 texts an hour, give or take.
Do the math.
Don't worry about your battery the first 72 hours. Your phone is basically "warming" up to all the new settings etc etc.
If the problem is still there after hour 80, there is a problem, and most likely with either the download or your phone is really screwed up (which probably isn't the case).
Thank you. That is all.

Hey guys I'm kind of new to the rom world and let me say i LOVE IT. So much stuff you can do with the android. I'm on a i747 galaxy s3 and I've just downloaded the Pacman rom.I've downloaded other roms so i know i flashed this one correctly. I even re flashed it again last night. Both yesterday and tonight my battery went to 100%-%50 in one hour. After i charged it up it would decline 20 percent in one hour. I look at the time screen time on and to see if anything is waking up my phone excessively. And all sings say to no. Any tips? I feel like I'm back in pre ics days haha.

when you flash a new ROM it is recommended to wipe Cache, Dalvik, Factory Reset and System. If you've done that you should be okay with the installation portion.
Have you modified the kernel at all, have you over clocked anything?
Go to the play store and download BetterBatteryStats. This will help you determine the cause.

Yeah i have. When i installed i did the whole wipe thing. And I'm useing gsm batter monitor. All the readings are normal which is the weird part to me. And no i haven't over clocked (No need to imo) and haven't modified the kernel. I know that on previous androids you would have to do a wipe batter stats. I actually tried looking for that in CMW but i wasn't able to find it. Would you have to wipe the battery stats using "batter calibration" or wiping it manually in CMW? Or is that even necessary for galaxy s3s?

I would also recommend using Better Battery Stats as it is the best one I think. I always use the battery calibration app after I flash a new ROM. It usually takes a couple days or so anyways to have the new ROM settle in and everything. After a couple days you should see your battery life where it should be and not draining so fast depending on what your settings are.

Battery calibration is a myth and has been confirmed by Google themselves. Its all over the forum and wholly unnecessary. Those apps are useless. The only way to truly let your battery stats "calibrate" is to let the ROM and kernel settle into the phone after a few charge cycles.
Here's the Google+ discussion by one of Google's people: https://plus.google.com/u/0/105051985738280261832/posts/FV3LVtdVxPT
If you want to keep "calibrating" your battery for the warm and fuzzies, its your time and device.

Wow thats interesting. Everywhere i go people say that battery calibration is a necessary part when switching roms. Just out of curiosity what do you do for better battery life ? Basically what you use and not use settings wise.

Everyone's battery life varies. Honestly, it doesn't matter the ROM. The kernel does play a part in it but its how YOU use the phone, display brightness, sync, etc. Way too many factors.
As for me, I get about the same life on most ROM's I use after letting the phone settle for a few days. The only constant I have is the kernel I use which is in my signature. Lately, I've settled on one ROM as the dev is on top of his game with this device. That ROM is also in my sig.
