I asked about the one with the best battery life, not the one that "nice to look at".

Hi,
During the time I tried plenty of kernels and roms, I was very impressed by the galaxy EE kernel for the battery life. With normal usage (phone, sms, download, games) but without 3g, my battery lasted around 4 days.
http://forum.xda-developers.com/showthread.php?t=1137595
About the rom, I did not test myself, but heared a lot of positive feedback for GingerReal2, which is very stable and smooth http://forum.xda-developers.com/showthread.php?t=1155623
If the rom is very responsive and does not have plenty of candy and shiny fireworks, this would mean you can tune your cpu with lower speed, which will lower the battery consumption (which is possible with galaxian kernel)
I hope it helped you ;-)
Have fun !
P.S. I am surprised that you have bad battery life with CM7, because it is a very good one for that point if I remember well... Did you try to tweak the system when you installed it ?

I have had cyanogenmod 7 and miui and try a lot of kernels!
Cm7 is very good also with stock kernel, but I think that Cyanofortomorrow v1.2 is very good! You can dwl it with stock kernel or with platypus kernel.
Miui is very nice but battery life is not the best! I have a mintberry rom with glitch kernel v13.
The best kernel in my opinion are glith kernel V13 HL (smartassv2, sleep governov powersave) and platipus neo 18 didle (deep idle). For less battery drain it's very important understand wich modem phone is better for your geographic area and operator.

Best Rom for battery life?

Hello Guys,
I'd like to know your favorite Rom ever for battery life, I don't care if it ugly or with bugs, I just want the best Rom for my battery.
thx
(and sorry for my bad english)

you might wanna look more at a kernel that's is what makes the battery life better also reset battery stats in cwm recovery

I find stock roms have the best battery life. If you really want to push it, get a basic rooted kernel w/ clock speeds (semaphore), and underclock your phone to maybe 800mhz.

try using a stock rom and a good root (semaphore/galaxian) and use low light display and underclock the cpu

Thx guys, I'm gonna try that, (sorry to respond 1month later lol)

can you please explain more about underclock your phone to maybe 800mhz

I use simplicity with special configurations in the semaphore kernel:
- Underclocking to 800MHz
- Simple-IO
- batterysave Governor
- autobrightness to dark
- darker-Voodoo Color
I also switch off Network and Auto-Sync with help of widgetsoid (see market) when not in use.

Hey, sindalf, what version are you running, I was on 2.11 using fugu(I think) kernel v3189, and my battery is not very good.

any rom with removed bloatware such as CM7 and others

try gamerz rom that is brilliant for bat life and removed bloatware

Back in the day that I didn't used MIUI ROM's I used Darky's and that battery life was great! Also the ROM was blazing fast.
Last version I used from Darky's was 10.2 or something like that (V10 for sure). Had about 2 till 3 days battery life. With slightly less usage than normal. And i must tell you that when I flashed that ROM i jys had a new battery.

battery life ... nothing more

hi there ...
since I'm using my p970 mainly as a wifi xbmc remote control, as a "fritz.box-phone" and sometimes some gps stuff only, I am searching for battery life as much as I can get.
I don't use mobile options cause I even don't have a sim card inserted. And I don't need performance or a snappy interface cause I just use barley a hand full of apps.
So I need ur advice which config is best for me. which kernel, gov ,launcher and Rom I should use.

get zeus v7
underclock your cpu, undervolt the cpu, change the screen brightness, use adw launcher or a lighter one, change the options of wifi in zeus tweaker allowing better battery consumption

How to undervolt cpu?

Zeus App/Tweaker

Ok, but if I use CM7?

Cm7 is known to suck quite a lot of juice.. better for you to switch to Zeus

I would, but I love sound in CM and switching songs with volume rockers

well a price for everything
battery life for music
is the sound really better on cm?
(i mean compared to power amp in stock roms)
does it sound louder and have a richer bass?

Yup. I tried everything (CiCi, Mercurified, Zeus, Nova), tried to apply fixes to switch music with volume rockers (it's sth necessary for me - i failed ) and cm is the best in my opinion.
It would be nice if I could change voltage...

So, use boype's cm7 and underclock and undervolt it

AFAIK does DVFS (feature of LG) already undervolt your CPU as far as possible, according to safe values of course. I think anything lower causes SoDs and other errors... You should take boype's kang, if you want to have CM7. I just made a test and got 1day 18 hours with normal use, so you can definitly get more out of it

Well I'm using boyope's cm7 and its sort of same as zeus v7 in battery life, just try boyope's then see for yourself since u want a cm rom

[Q] Battery-friendly ROM

Hi guys, maybe you read this question a lot of times...
In your opinion which is the best battery friendly ROM for our device atm? I don't really care about performance aspects because I'm not a gamer

I get +/- 1 day on stock JB (GPS always ON, data always On). Last time i tried CM (RC2) i didn't get 6h...

I'm currently getting a decent ammount of battery life with CM Nightly 20130613 + Idoak v6 kernel.
Also Stock ROM with Idoak kernel is good aswell. Just have my Governor set to Interactive and seems to do a pretty well job.

From what I've read/heard around. The CM RC version are alot more buggy and problematic than the Nightlies. I haven't tried the RCs myself tho the Nightly does feel pretty smooth and stable.

Which firmware?
Sent from my LG-P880 using xda premium

ROM has little to nothing to do with battery life, aside from the obvious settings you can select to turn opn or off features. what does influence battery life is how you use the phone and in particular 3 key elements
1) Kernel - Stock kernel is pretty limited, using alternative kernels will allow different governor and scheduler options along with frequency and voltage control
2) Tweaks - many unsuspectable little things can change the way your phone drains, probably the best way to start is getting pimp my rom from the plauy store
3) Apps - You will need apps to help managing and scheduling when and how the phone drains. LBE security master or any other task manager will prevent unwanted app startings and others like juice defender or other battery saving programs help with which interfaces are on and when.
Also keep in mind that if your phone is new the battery in the first 3-4 days need to settle and will change drastically behaviour.
Hope this helps
In any case a catania sto telefono te lo fanno prima della terza ricarica quindi non mi starei a preoccupar troppo

Grazie XD
In this case which kernel and governor do you suggest me?
Sent from my LG-P880 using xda premium

Stock rom, remove LG MLT and Google Backup Service and you should be good.
I can leave my phone for 2 days without worrying about charging it. However, with screen set to 50 or 100% brightness, the battery drains very fast.
Otherwise, keep your screen brigthness low and get a governor that lets you throttle the CPU. At 800 MHz,you should be fine. Also, dont use auto brightness, it will not help.

Thank you which firmware?

EuroOpen V20A if stock or CM, some nightly between RC2 and RC 3(Thats the last ones I tested that used to be good)

Could someone help on what r the steps for install custom ROMS and Wich one is the best for battery life I'm having very very huge battery problem. The battery it's long for about 3 hours tops and I need to keep charging always and also the overheat is extremely. I will appreciate ur help

Sorry but you should write a new topic for this problem... Anyway there are several guides in this section that revolve about how to install custom roms. Try looking there... However generally after installed a recovery you should do a full wipe (data/cache/dalvik) -> install zip from sd card -> choose zip from internal/external sd card -> [file directory] -> choose file -> yes

Im using iodak 6.0 and latest CM nightly builds. Battery is much better then on stock ROM and kernel.

I dont know if iodak improves battery life, but I do not think that battery improved with CM. It actually got worse for me,

XenonHD + iodak v06 has been very smooth and battery friendly. A day and a half of moderate use and I'm sitting at 18%

[Q] Lower quadrant scores with cm 10.1?

Try different kernel and different combination of scheduler and governor. Every kernel have a "performance" governor.
Btw don't forget that the benchmark are not really representative of the true performance of a device.
It is always good to have some big numbers, but some benchmark apps can be hacked easily to show to incredible scores (and in particular Quadrant).

same for me. closest i got to stock was running pure aosp.

But without looking at the scores, how the performance of your phone in games with cm10.1, isn't the global interface smoother, aren't the games faster?

I heard this rom has an amazing battery life so maybe you should stay on pure AOSP and try a different kernel

CM sucks. Seriously. Some games do run better, but sadly some run worse too. Seems to be the more complex ones that depend more on I/O performance than the cpu/gpu

Did you install CM nightlies? I heard they are more bug-free and has better performance than RC versions.By the way, don't expect any custom ROMs to be faster than stock ROM for the moment, most of them has a lot of bugs or performance issues, stock ROM is the best choice for now.

The screen dim can be disabled by renaming or deleting /system/bin/thermald. Which kernel are you using? I find CM to be laggy in my games, there are exceptions though, NFS MW is very smooth, but NOVA 3 and modern combat are very laggy
