Heavy battery drain on Gingerbread

Hey Guys,
I've been trying out many roms in the last time and I've noticed that on every Gingerbread rom, the battery drain is much higher than on Froyo roms. That's weird, because I constantly hear of people's battery life getting better after switching to Gingerbread.
On Froyo, the standby consumption is at 5 mA. On Gingerbread it's 75 mA. On Froyo, I can surf the internet for 10 minutes and nothing changes, on Gingerbread the battery would lose 5%. With regular use, when the phone is full in the morning, it's almost every day empty 8 hours later.
I just want to have a Gingerbread Wildfire with decent battery life. I tried many roms, and even on CM7, battery life is horrible. Even on a clean install without any apps. What is going on there? Is it maybe the radio? Or the kernel? Do you experience similar drain?

Maybe CPU?
I dont know if this will help but Gingerbread roms often have overclock settings, have you used the overclock feature because this would most definatly reduce your battery life but otherwise im not too sure but i must say i was using Oxygen (Gingerbread) on my wildfire and the battery life was very bad compared to stock ruu roms, sorry if i didnt help :S

Any idea? Im about to upgrade to the gingerbread.

I know about that, but I don't overclocked my Wildfire. Just because the battery drain is heavy enough on regular CPU speed.

Just upgrade and see yourself, I heard about many Wildfire users with Gingerbread who got better battery performance than on Froyo. Unfortunately, I ain't one of these

After a new flash it's usual to have battery drain. After a few charges it will buff out.

underclocking ur cpu is a propable way to go. actually using conservative governor in cpu settings, may help your battery efficiency. but before doing this, search for a thread concerning this matter. u can always give it a shot and see for yourself, decide later if you want to keep gingerbread or not.

Is stock ROM less battery drain??

Which rom is the best [for battery life] between these one??
- cyanogenmod
- miui
- stock ics
All with the ultima kernel from riyal.

For me its KA21 with Arcknight 3.3 Stock Kernel.
Really smooth, better battery than i experienced stockwise...

try ICS_anzu_KTG tuned_V1.41: governor interactiv

actually battery drain more depends on the kernels..for best battery life stock kernel is the best

Guys note that lad has Pro not Arc. Stock is usually the worst, or better - default gauge for custom ROMs. I've been watching cyanogenmod discussion for a while, usually users feedback on battery life varied from version to version; for tweaked versions can be said that battery life is the same as in stock while the performance is 20% better. I don't know about MIUI.
(Out of your question, the best for battery life are Ultima ROM and Buttermilk ROM which are optimized for battery life and battery life is notably better there; with Buttermilk and low usage you can do as much as 4 days without charging - worth for outdoor trips. Ultima ROM when idle eats like 0,6% per hour.)

Stock rom with stock kernal had the best battery life... but also lags the most.
I recomend arconium ICS with stock kernal for a balaced experiance...!!!

Well if you game a lot compared to someone who doesn't then obviously ones battery will last longer than the other, so there's a few factors that can be taken into account in regards to battery life.

well my method of testing battery drain(i guess everybody tests the same way) is only on standby..how much time does it take to move 1% down when the phone is not touched for an hr or 2...in exceptional cases battery will drain fast while using 3G in one kernel but lil slow on other kernel..
again my point is kernel is more responsible for battery life of the phone rather than a ROM..

Then you need to take syncing into account, if yours is on and mine is off on the same kernel then yours may drian a bit quicker than mine, which goes back to my point of how a user uses their Phone. I don't think it's a black and white issue.

yea dude.. i get it..my point was simple..people were talking about best roms for battery life.. i just said kernel plays an important role in deciding that..that was my only point..i wasnt arguing with anyone..and testing of battery drain at standby means with data off,bluetooth off, gps off..hence syncing of account wont come into picture

I'm not arguing, just trying to make a point also.

As u can see [in my signature] im using ultima KERNEL. Is there also a ROM [for ICS}?? And is it possible to downgrade like on the iPhone??

Yes I know and sorry, the last two ROMs I was refering to are GB. However, Riyal is working on Ultima ICS ROM and it already exists in alpha version! See this post with download link Hopefully the ROM will have similar advantages as has GB Ultima ROM over GB stock ROM, which means better battery life, better wi-fi reception, improved camera and so on.

I did that when I had iPhone 4.

im using cm7.2 latest release alvays, i also have an app set cpu and i set my governor to scary, min freq 145 mhz, and max 1024, and im using profiles for apps that im using most of time (underclock cpu while using that apps)
with that i have at least 40% better battery life
and, yes, u can downgrade using flashtool

So far Arcknight kernel has quite the reputation for good battery life. IMO, for roms i find CM9 from FreeXperia project quite awesome but then there's an issue with the battery stats and brightness for now so wait for the next release i guess. for GB try arconium 8.2. still mostly its based on kernel and also the governor.

Hey friend, how do you do that? I dont ahve that option.
I remember i had on my other phone.
Im running the newest version. Should I change my device??

What option are you referring to?

Battery Life in ROMs

Hello all,
I was looking for input as to which ROMs others have found gave them the best battery life, whether it be from a custom kernel, or battery saving features packed into the ROM itself. I am definitely open to opinions too, doesn't really need to be statistically backed.
Just and F.Y.I, I currently use the last Miui.us official supported ROM for the G2 (Just before v4).. For a long time I've had held to the belief that it offered the best degree of battery life for features provided; a trade off, as one might say. I've tried the older Cyanogenmod (back in 8-9ish lol, actually had worse battery life experience than MIUI) and virtuous (urgh, not too much luck, looked nice, buttery smooth...when it finally loaded..G2 doesn't seem to have enough RAM to have any kind of app running without reloading that pesky Rosie launcher) and a few other less-than-well-known ROMs.
I would also like to add that I have steered clear of ICS ROMs, mainly for the fact I can't seem to find a clear superior version that's stable, that also goes for recent sense ROMs, i.e Sense 4.
Any and all advice/opinions are appreciated
Regards,

MIUI
So far I've had best battery life with MIUI, without any tweaks. I think its beacaue most of other custom roms, specialy ICS and sense 3+ roms are overclocked for better performance. Overclocking=Less Battery Life.
From my experience CM7/9 also have a good battery life. If you want more you can reduce max-cpu-speed and min_cpu_speed for lower values. 245Mhz and 800Mhz. this should do the trick. and use some app like Juice Defender. it helps a bit.

I run one of the older AOKP builds and while off for a few days and very light use, had ~20% at 44 hours. During normal days I run quite heavy with BT and wifi hotspot, I can drain it very very quickly.

Elitemod cm7 was the best for me. 10-12 hrs easy heavy use and is real smooth.

Yeah i used elite mod at some point also.. I think I may go back to it now.

I'm getting about 80 hours of light usage (~20 sms and 2 calls, maybe little data, per day) on latest official Miui GB (2.3.23). But with heavy usage (games, wifi, music) i can get it down to 12 hours.

That sounds about the same for me on miui...anyone use juice defender or undervolting? I actually still get like 12 hours moderate/heavy usage clocked to 1587mhz smartassv2.
That 512mb ram optimized Sense4 is looking pretty nice right now though..

Speed and batttery life

Hi there Gio users. I want to install a new rom on my girlfriends phone and I would like to know wich one is the best in terms of speed and battery life. She uses Phiexz's CM7 now and the battery life is awful so she wants something new. I have studied the market to say so and from what I've seen she has to choose from these 3 options: LightOrange, Enhanced236 and DebianDroid so I would like to ask you which one do you think is the best?Or do you have better alternatives? Thank you so much, have a nice day!

enhanced 2.3.6 ... its with aroma so you can shoose ur add-ons and good baterry because stock based .. before flashing charge the phone 100% and do a battery wipe @
advanced then wipe battery stats

Battery Wipe = Placebo stuff.

use the last cm7 release by marcin1147.

[Q] Rom or Kernel

I know alot of people ask which is the best combi, but i dont care about that.
im wondering which one really affects the battery more, the rom or the kernel?
im looking for more battery life and i constantly try many roms and kernels to find the best, but its all very erratic so im wondering which one i should change and look for increase in battery life more
tks

99% of the time it'll be the kernel that changes your battery life (exception being if you're running a poorly written ROM, which is unlikely). Kernels give you the ability to tweak your phone for better performance or better battery or any combination of the two, whereas ROMs more or less just change the user interface. I have gotten pretty good battery life on Tiny's kernel, so you could try that, but you could ask 20 people, and you'll get 20 different answers for the best kernel haha

Yep its said kernel affects battery. My experience over a multitude of android devices says neither have a noticeable effect on battery life. I flash kernels for other reasons, not battery life. I've always gotten similar battery life on stock setup vs any combination of ROM/kernel. Maybe SLIGHTLY less battery if the kernel was geared for performance, but never have I seen a noticeable increase in life.

Xenon and Trinity kernel !
Sent from my Galaxy Nexus using xda app-developers app

Biggest battery draw is going to be the one you didn't mention. Apps. Specifically the ones that run in background syncing data all the time. Try a little experiment by going to your mobile data usage, setting a limit and then disabling background data and auto sync. You'd be surprised how much battery Google now sucks down

i was using AK kernel and my battery was dying in a matter of hours. Ive been using Trinity and I've had great battery life.
