Terrible battery life help

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?

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.

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

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.

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

Which from do you get the best battery life??

I'm trying to hunt around for the best battery life so let me know your opinions. Thanks

Best battery life would come from one of the debloated stock roms most likely...but it also keep in mind not every phone reacts the same way as others do to a Rom...one person may get amazing life on one...while another gets terrible life on that same exact one...

I've been running legend rom for the past 2 weeks, been great.
before that I was running the unofficial cm9, that was awesome-only problem was no bluetooth.

that's what I was on before this. I am actually thinking of switching to something that has Bluetooth for the time being until they get a patch on RemICS. Its the only downfall!

Although development had stopped, Zeus had the best battery life for me.

erytherm cisa).
Zues was pretty good,except I had SOD issues several times a day, wiped, reinstalled, re-downloaded, went back to stock, rooted again, reinstalled, nothing seemed to fix the issue

For me most of the bigger gb roms all had good battery life. (legend, aeon, zues, emacipation).
One of the best roms ive used as far as battery was actually dman's catyrom. With pretty heavy usage.
But ive found out that using better battery stats to track down battery hogs is a must for any rom.

For me, cm10 gives better battery life than stock Sense. I think it depends on how you use your phone.

I'm using Baked too, but for me battery life is just great! Actually on 57% with 8h 27m and almost 1.5h screen...

Of course rooting for battery is a good idea. Undervolted & underclocked kernels, delete bloatware that's constantly running, etc. And as far as best battery life, baked has been very kind to my phone.
A typical day for me (7am on phone for 2-3 hours reading the news before work, music to/from work, light usage on breaks, then hotspot at home for internet, and all the calls/texts in between and countless downloads) will leave me with 20-30% battery when I go to bed around midnight

Currently on slimbean 4.2.2. have gotten a few random reboots..not enough to make me change though. Video player doesnt work, kinda of a bummer. If you love your GPS and wifi, then stay off this one for a while. Battery life is great but he random reboots tend to kill it off prematurely,

Talking about SlimBean 4.2.2 or the 4cyl script? If you're talking about the base SlimBean... irrelevant to the usage of the 4cyl script.
Regarding the 4cyl, the 0.4.2 seems to be decent with the 1.4 NOS entropy script.

Yes,it's work fine ı dont have reboots and everything stable.I have 1500mAh battery and ı always have 3g, the battery life is %19 11 hour on battery.:good:

Working stable for me. Switched to using 4cyl (0.4.2) for standard bits and Crossbreeder for entropy/adblock, based on what people were saying in the thread. Which means installing 4cyl, running the entropy uninstaller, and then the CB install.
With mostly light usage, phone is at 78% battery after 5h41m57s. 16% Android OS, 13% Wi-fi, 12% Android System, 12% Cell standby, 9% Screen. So you can tell that it's still the JB battery burn due to GPS, but overall? Not too shabby. And I could save a bunch of battery if I wasn't lazy and left Wi-fi on all the time.

Good lookin

[Q] stable ROM with good battery life?

So my wife has an LG G2X on stock android 2.3.4 and she complains that after a while it will move so slowly that it is almost unusable. I have told her to restart the phone whenever that happens and she is having to do that about once a week, but that clears up the problem for a while. Aside from that, everything works as it should. It is using the march 2012 baseband.
Since it is not my phone, I do not know exactly what all she is doing on her phone, but I assume it is mostly facebook, watching videos, texting, and calls. I'm looking for a stable ROM where everything works like stock and has at least the same (if not better) battery life as stock.
And yes, I have searched but a lot of the info seems outdated. I am thinking that I might just run a rooted stock ROM with a custom kernel (leaning towards faux's here: http://forum.xda-developers.com/showthread.php?t=1102720 )... or maybe the stable cm-7.2.0-p999
summary: wife's G2X becomes VERY laggy after ~1 week use, suggest a fix
thanks :good:

Having to restart once a week is not problem, if anything that's a good thing lol. I had to restart my stock unrooted g2x multiple times a week.......if you move to a custom rom your wife will probably have to restart about the same if not more. I'm on cm7 and i restart about once a day just because i like to, not out of necessity. If your wife isn't huge into customization than a stock rooted rom will work just fine. Faux makes a great kernel but it was a little harsher on battery for my liking. I'm running Trinity oc right now and love it. If i were you, i would look at mazouts latest kernel build. He makes AWESOME kernels and ill be moving over to his latest release whenever it comes out tonight or tomorrow.

i had her on a cm7 build with her previous phone (motorola defy) and she seemed to like it OK. didn't customize it too much, just used all the default settings.
after i posted this thread, i actually started to look at, and downloaded mazout's kernel... so now i'm thinking of trying out the 3/1 "nightly" build of cm7 with mazout's 0323 kernel. i can't seem to find a known bugs list for cm7 on this phone. are there any known bugs?
does this build of cm7 have a "restart" option in the power menu? that is one of my pet peeves with the stock ROM. the only way i have found to restart the phone is to "power off" and then "power on". i think she would be more willing to restart the phone if it was an automated restart

Yes there is aa "reboot" option that comes up from holding the power button. Maz's 0323oc kernel is awesome. I wouldn't put the Max over 1015 and keep the minimum at 216. Known bugs.....for me the only bug i had was the phone would heat up pretty bad overnight while charging. It was instantly fixed by going into my development settings under applications and selecting the "keep awake" option while charging.

threw "fast reboot" on there to see how she likes it since it doesn't require root, works more like an app killer, but kills all in one press.
now, would i see any noticeable gains by using a custom kernel (stock voltage, no overclock)?

Yes, not an extreme amount but a definite yes. I know by experience with CM7 that mazout's stock voltage beta kernel was much better than the stock CM7 kernel. Those kernels are only for CM7 though. I do not have any experience with an upgraded kernel on my g2x while it was stock as I flashed CM7 and mazouts kernel right after.

^ those stats are kind of irrelevant considering he's asking for a decent play out on battery while using performance. [All around use.] You just showed us what a phone with no data signals and almost no use other then the odd screen wake [possibly texts/calls] the op explained he needed a ROM that takes minimal battery with most use, and being a girl I would imagine she's using social networking which requires WiFi or 3G/4G Please don't take what I'm saying as offensive, your information is very handy however it steers the op in the wrong direction as I'm sure his wife likes to use her phone as much as possible without being stuck to a charger. My girlfriend is currently using my old g2x and so far we've had the best luck with cm7 stable and the trinity kernel with slight under volt. What I would suggest the op do is maybe take a little research nightly on her battery drain, find out what she's using the most and go from there. Unfortunately because its not HIS phone, he's not going to witness distinction first hand and won't be able come to a easy conclusion, and it doesn't help that the g2x devs are stuck on GB, too many ports to keep interest and the search could take forever.
LETS KEEP PRAYING TMOBILE HASNT FORGOT US!
PS spawne32, when you did have your phone like the picture did that include battery apps or task killers? Or just straight up OS? Whenever I tried the ROM you suggested [it has been a while, maybe since updated.] I get screen wake issues and all kinds of battery drain.

To the op, also recommend to your wife the app called "screen filter" it has an option to lower the key brightness, there are a few of those apps out there but I only remember using that, one of the g2x sad but true battery drainers.

Similar issue - frequent reboots - please suggest ROMs, kernels, other solutions!
I have an LG Optimus G2X (P-999) running the original, unrooted, stock OS (android 2.3.4 "gingerbread", with the "old" bootloader and the baseband from March 2012).
Similar to the OP's wife's phone, mine is running slower and slower, frequently locks up, sometimes so badly that I need to remove the battery to restart it, and sometimes it just restarts itself. I've already tried uninstalling unused apps, clearing caches, moving apps to the SD card, etc. None of that seemed to noticeably help, and lately I need to restart it at least once every 24 hours.
(There are other annoyances too, like the way the GPS hangs and drops, and the battery life isn't great - although the battery may just be too old.)
I'm planning to root it and uninstall the bloatware as a first step, using the instructions I found here: http://forum.xda-developers.com/showthread.php?t=1050534
Then, I'm considering installing a custom ROM and/or kernel. (Most up-to-date list, I believe, is here: http://forum.xda-developers.com/showthread.php?t=1975934 )
Given the problems I'm having, do you think one or both will help? (If yes, do you have any specific recommendations for a ROM and/or kernel, or tips, or possible pitfalls I should avoid?) Are there other ideas I should consider?
Thanks in advance!
