Faux or CM?
Sent from my LG-P999 using XDA Premium App
The stock CM kernel is probably going to give you better battery life but it depends on how you use your phone.
Are you asking about roms or kernels? Your post is vague.

Talking about roms, sry. I'm running cm rc1 and I don't get the best battery life. stock kernel with cm
Battery will last much longer if you remove it from your phone and store it in a cool dry place.
I have tried both of these ROMs and get good battery life with either, make sure you do a battery calibration after changing ROMs, this has improved battery life for me from 8 hours to 1.5 days with the same ROM.
ok so i got my charge 2 days ago and am rooted with Gingerbread leak,
so i have some questions.
First: is there roms for gingerbread? because i couldn't find any.
Second: what kernels are there for GB? can i use PBJ?
Third: now ever since i got the phone it drains batter pretty quick with everything off. and hardly using it maybe about 20% per hour. i tried undervolting with Setcpu but wasn't successful, so what app do you guys recommend to undervolt the charge? or any guides to do so?
thanks,
Check out the development section. Gummy Charged GBE is great

I did, thanks for the reply. now i have voodoo and on the recovery sais enable 100mhv something like that. is that so i would get more battery?
You can't undervolt on gb because its a leak meaning no kernel source.
I think setcpu will let you underclock which would give better battery life but reduce performance considerably.

Whenever you change roms, you should calibrate your battery. It works wonders

You need to return to stock, then fresh Odin GummyCharged GBE 1.9RC2.3 if you want Gingerbread as it's really the only modified Gingerbread rom. Eclipse is available, but i'm not sure if the dev still supports it or not. The quick battery drain is something that goes along with the fact Gingerbread is a leak. GummyCharged team has done a wonderful job with minimizing this drain. I have found it actually has better battery life than Froyo. That's just my personal experience.
Which one would have the best battery life? Or if it's a multi-step process (pick a certain rom then change kernals or something) could you link me/tell me also ?
I'm using Octane v2, and it worked good for the first day, but now it's draining my battery so quickly, even after the battery calibration. I'll lose 2% battery while watching a video for a minute or two.
airfluip1's KJ6 AOSP Style
I haven't done much testing but for the last few days I've been using airfluip1's KJ6 AOSP Style and the phone's battery just died after being off the charger since late Sunday. That's almost two days of juice on one charge.
I also have had excellent battery life with the MIUI ROM variants around the forum, but they are still works in progress and aren't feature-complete yet.

I don't think battery life will differ much between the roms we currently have available, as they all have a stock kernel.
Though under-clocking and juice defender work well for me, I am a heavy user, I've not been able to get more then 14 hours of use.

How can I under volt it? I am using icbin's kj6 add on
Sent from my SGH-T959V using xda premium
to undervolt, pay for tegrak ultimate from the market. then input dsexton's undervolt values from icbinb threads.
I found a way to not pay and u/v but thank you !

Hey xda, Ive got this rarely used g2x. Don't even got a simcard for mainly using it for fun I guess but I am gonna get it in service soon. Thing is I am getting terrible battery life on all recent roms, eb gb and ics and Hellfire gb and ics, I got stock battery, even with kernals my battery's terrible, looking for reccomended roms and kernals and any tricks/mods to improve battery life, and remember this is even without any data usage and am still getting this amount of battery life.

You never told us what you have tried, or what kinda battery life you are getting. Also did you put the phone in airplane mode so it isn't looking for service?
Sent from my LG-P999 using xda premium
For example I just turned the phone on from after being in the charge for 7 hours, i then immediately went to xda app and then checked the battery and found it at 96%.

I dont remember which kernels specifically but I did say which roms, I've flashed all.of them atleast twice but am willing to do so again.
Sent from my LG-P999 using XDA
I've found that ICS roms are horrible on battery life. Also, like mt3g said, put it in airplane mode since you aren't on a mobile network. Take a look at this thread too http://forum.xda-developers.com/showthread.php?t=1054420
Should I use Hellfire or eb gb, I've heard that eb is better but hellfire's gb was updated more recently, and which suggested kernal to go with it. I understand that it all depends in your phone but what in.your experience / opinion is the best combo.

The rom I'm using right now is Eaglesblood build 2.8 which is GB 2.3.7. I get pretty decent battery life just using the kernal that is built into it normally. I was having a few problems with HFP 2.1 so I switched to this and haven't looked back. Even though it isn't the most recent I still feel like its the best, just my opinion though.
I have got the best battery life so far with Eagles blood GB as well. HFS v1.5 is giving me ok battery life but EGB gave me double time as this ROM

Most recommended kernal with eb, looking for optimal performance with good battery life

Try them out, read the threads to see common issues and things that work well. Stop asking everyone here to do that little bit of work for you.
XDA is not your personal slave, we should not, and will not spoon feed you. Look around, spend more then 2 minutes looking at the first post. If you put in a good effort, people will be willing to help you, but just constantly asking for which ROM is just lazy.
You did not answer the question of whether you put the phone in airplane mode, you have not said any of the ROMs you've tried (other than all of them, which I doubt). At least pretend to give a ****...
Search!!!! there are tons of threads on how to increase battery life

? I don't think you give a **** because if you read my post you would of known that I'd have tried eb ics and gb, and hellfire ics and gb rom, and i've actually spent hours reading pages in the roms topic and other places, and I forgot to answer that question, my answer is no I don't even have a simcard in the phone for it to be searching for service and enabling it would stop wifi which is what I do use.
You can put the phone into Airplane mode and then enable WiFi. Even though you don't have a Sim install it can still try to search for a network and drain the battery. It will need a network without a Sim to be able to call 911 if needed.

I flashed Trinity's elp and now I cannot get a battery reading, I have a question mark at the symbol thing at top of the screen and every battery reading is 100%. Any fixes? I also am getting a slower start up from screen off, but ill try v6 supercharger.

Just go back to the kernal you had before and it should be fine
@ctowne... I would love to know what you are doing that makes your battery life that good with a stock kernel. I'm running cm 7.0.2 and I've charged my phone a couple times through heavy use. I have cut a lot of the processes down and did all the troubleshooting to get better battery life and its still draining like **** during heavy ( or what I would call heavy) use

I don't think its necessarily the stock kernal. It's the one that is built in to Eaglesblood GB. Also try to follow this guide, it seemed to help my battery life. http://forum.xda-developers.com/showthread.php?t=1054420 I did get around 30 hours on that charge but it varies quite a bit depending on usage. I always get a full day of moderate use though. Try switching to Eaglesblood GB and follow that guide to 20 hour battery life and see if it helps. If not, your battery could just be old/bad. Hope this helps!
Yeah i tried the eaglesblood rom and wasn't too impressed. Im sure that it was good for performance, however i immediately missed the customization with cm7 (adw launcher) and the themes that came with it. after i have flashed the faux123 kernel on here with cm7, im happy to say my battery life is incredible. i fished all day yesterday and listened to music while texting a bit and making a few phone calls. was out for about 10 hours and had only used 40% of my battery. so for anyone looking for a good cm7 kernel, the faux has been the best i have found yet
I was pretty pleased with my results here, so I thought I'd share. This is done with both OC and UV and making use of the the 3500mah batt and with moderate/normal use.
I can get that on stock battery, you must play some games and leave your phone on full brightness at all times or something.

No, I play one game in particular, and I spend more time on the web on my phone than most people do on their computer. I could get that on a stock battery too, if I never actually used my phone Before the the changes I made, I was getting significantly less life. Especially with OC.
It looks like the moment you turn your screen on your battery life plummets.

Thats from Oc'ing to 1560 lol
It's more useful to post test results on a standard battery and standard voltages and clock speeds so others can compare. I've gotten 3 days on stock CM7 nightly before, it really depends on how much one uses their phone. The biggest clue to how a ROM or kernel affects battery is to look at the idle drain (maybe with data off too). It should be flat or with < 0.5%/hr drain.
Where'd you get the 3500 Mah battery you are using? I've been trying to find a decent maker for one.
