Best battery life ROM?

I'm trying to deal with cm7 but little things are killing me (battery life stinks even with extended battery, I watch my battery fall with the screen on, it's good when it's not though. Constant problems with my lock screen freezing, etc). I'd like to find a rom thats 100% stable, aosp is preferred, but not a must. Any recommendations?
Thanks

I alway found CM6 and Miui 2.2 roms to give great battery. Not sure if you were looking to stay with gingerbread though...

Cm7 just isn't as good as cm6 that's all I will say. My battery life on cm7 was not so great. I switched to miui for the first time yesterday and my 10hrs turned into 15hrs already with 50% left. Usually in about 10hrs my cm7 is on about 10% left. I actually have a pic to prove it lol.

With CM7, I usually get 12 hours to 50%, 18-20 hrs to 20%. If your battery life is that bad, I would try calibrating that battery and checking for wakelocks.
Also, try decks gingerbread which is based on CM7, but gets better battery life. You can find it under the thread "yet another AOSP ginger ROM."

+1 to this, I get great battery life with Deck's

I installed cm6.1.2 and so far all is well. I don't really have any reasons to stay with ginger bread, the only thing I even noticed from it was the screen off animation. I rarely use 4g, so its not a big loss on that. Any recommended kernels for cm6.1.2?

I'm all about Tiamat

Destroyer v 2 with savage zen kernal and I can make it two full days with mild-moderate use. Heavy use will still make it all day. By far this is the best battery life I've gotten.

When I switched to Tiamat I started getting great battery life on CM7. I can get 18+ hours on it, easy.

can you still use CM7 themes with decks?

I get 15 hours with cm7 SZ kernel with moderate use
When I check the batt stats in settings, "phone standby " always has over 50% someone knows why?

This has been looking good and it was just updated this morning with no issues..
http://forum.ppcgeeks.com/cdma-htc-evo-4g-development/141521-4-15-11-rom-gingerbread-evo-deck-pre2-1-0-a.html

Buy 5 batteries then you will never be out of power.

CM7 (every nightly) and latest Tiamat. I leave BT and WIFI on always, without *trying* to preserve battery, and I easily last from 7AM to 7PM with no charging... running pandora for at least an hour in the morning off WIFI, and some in-car BT Pandora streaming... no 4G use, and tons and tons of texts and internet browsing. Same use on other kernels would have killed my phone in 4 hours easily. I used to be able to watch the battery indicator drop. Sense ROMS were pretty bad too.

Whats wakelocks?

Deck's + Tiamat = win

I suggest finding a kernal for your rom. Tiamat is a great choice.
Also, are you coming from sense? If so, resetting your battery stats might help.

I've had great luck with Vaelpak 3.2 rc1 and rc2, both with there stock kernel and 4.3.2 CFS SBC HAVS MORE. I mainly use my phone for texting and Facebook. On a typical day of moderate texting, Facebook and a few hours of calls I'm getting roughly 16 hours. If I use juicedefender and setcpu I can stretch it out even more. Vaelpak 3.2 is a non-sense rom and is very stable. Out of 4 or 5 roms that I have used this is the most complete and full Rom were everything works. Been using vaelpak for over a month now and haven't found anything better...
Evo 4g
Vaelpak 3.2 RC2

This has been my biggest struggle so far as well. Finding a rom that is both useful and does not kill my battery...I just rooted last weekend and so far have tried at least 5 roms looking for the one that I really get along with and like the looks of, etc. All I cal say so far about roms and such is trial and error...keep flashing till you find one that fits.

Battery drain by ANDROID OS

Battery drain by ANDROID OS
5hours 50% battery gone..
now using simply honey 3.3
how to fix it?
>.<

heard a lot abt battery drain in GB ROMS.. but i m on darkys v10rc6(2.3.3).. and i felt the battery was better than v9.5(i.e the 2.2.1 based rom)

last nite after a call..then i slept
wake up saw my fon battery gone >.<

any way to fix it?
is it the problem of TWEAKS and EXT MGR setting?

I tried Tweaky Rom after using Stock JVH and i like the whole Rom and lock screens and etc , but my battery wouldnt last more then 10 hours , flashed back to Stock JVH , rooted , flashed KC1 modem and getting 2 days easy with moderate use , on Tweaky it would drain about 15% every few hours , to bad as i like his ROM a lot
Hitec

u means TWEAKS and EXT4 will cause the problem?

Android OS battery drain issue is explained here.

although people argue wether it works or make sence the following sorted it out for me on dakry v10RC6:
using Titanium Backup
:delete data of
-Samsung Account
-Software Update
and freezing Software update
Afterwards I didn't face the drain agan I no negative sideeffect yet

thanks..
so my phone drained all battery also will solve the problem itself,lol..

just try to wipe batt stats from CWM make sure you full drained battery first and charged to 100% then go to cwm wipe batt stats remove charger and reboot.
**disclaimer some what related
as per codeworkx
Why my phone only charges to 94%/96%?
The Android OS wont ever let you actually charge to 100%, because charging it to 100% would wear-out the battery alot faster then charging it just under maximum.
On Sammy Roms it just usually tells you its at 100%, when its really at 94%/96%

No as you're more or less forced to do a clean install maybe you'll be luckily afterwards having well working system

problem also appear again =(

get systempanel from market so you can get more details about exactly what process under the system is using the cpu.. but my guess is it is the std suspend bug in gingerbread... that is why i am still running froyo.

I did not found solution too, now I am staying away from gingerbread as far as it is possible.
I could add that my 4 month old micro sd kingston class 4 suddenly got 8 bad sectors maybe ginger was on it for too long...

jbdroid's link helped me alot on this issue. I'm running Tweaky's and almost did what Hitec did, because the rom would deplete the battery in 6-8 hours occasionally. Stock JVB would last 36 hours on average. So every once in a while I'll pull the battery, sd card and SIM wait a few minutes and re-boot. It's not much of a problem because I have a mix of batteries with different capacities (3500,3000 & 1950 mAh) and I charge them on external chargers exclusively. I also wiped the batt stats and calibrated. I installed a program called Autostart, which kills some services like updates and maps after start-up. Now I get about 20-24 hours use, not as good as stock JVB but acceptable enough to stay for a while on Tweaky's. And the speed is a good trade off over stock.

You are not worried about your nice phone slowly dying ?
Things you did have absolutely no impact on this HUGE GINGER BUG. On darkys 9.5 i have 72 hours standby or more that i have never recorded because of course some usage in the meantime always happens.

battery life

Just thought I'd give a quick review of Cyanogen Mod 7 battery life and performance.
Standby battery drain of about 1.5%/hr with 3G, backround data on, auto-sync on, wifi on, GPS on.
I've never obtained such great battery life on any stock rom or stock-modified rom (I've tried a few different ones over the last year or so)
The performance is also much better than any of the stock-based roms (no lags).

No need to create new topic for that information.

fan/zombie boys everywhere
aple has ones so why not android ;]

Which nightly are you using? Which kernel?

After a night my Galaxy S is always dead. I solved the problem disabling 3g connection and sync. Stock rom 2.3.3 and semaphore kernel.

Sorry to say but useless thread. Just keep the damn charger always near you and battery life wont matter.
Btw did cyanogen pay you for posting this?or........

haha I had the same thought

I used to always hear about CM7 having god-awful battery life. I don't know if people were lying or if they fixed some major bugs, but I certainly have no complaints about my phone's battery life (running CM7, of course). I get through way more than a day.

That's my current battery stats. Haven't used the phone too much the last little while, but getting over 24 hours is not uncommon—I actually very rarely see my phone last for under 24 hours, and that's usually because of 5+ hours of screen on time. For that battery, I'd say about 75 texts, 30 minutes of phone calls, and about 30-60 minutes of web browsing. Fairly light use, but nevertheless, the battery life on CM7 is nothing to complain about.
EDIT: Looks like something was causing a wakelock the last ~6-8 hours while I was asleep, causing my phone not to deep sleep. If that hadn't of happened, it would still have quite a bit more battery (when I went to bed it was 44%, so it shouldn't have dropped to 27%—it should have dropped to ~40%). This just proves my point even more: battery life on CM7 is not bad at all.

seriusly?
do you see any battery change in that period compared to one earlier ))
when it was awake on your funny screenshot it was discharging with the same when the phone was not awake acordding to that stats so no impact registered

Thanks to share that information...

Best battery life that I've seen, using cm7.1 stable.
Currently at 2 days 1hr 15 mins with 14% remaining.
Wipes the floor with friends phones on stock roms charging every night. I only switched toCM7 after darkyrom barely lasting 12 hours at times

This sounds fantastic, Cm7.1 is my next choice, on XXJVT battery life is only 12h

thats using juicedefender to activate the data connection when screen turns on, emails still push to phone straight away with gmail so it is fine for me.
WIFI seems to drain the battery a bit quicker but not enough for me to bother flashing different kernels

I saw someone who did 2 WEEKS without charging. Normal using with black wallpaper on 2g network.

seems to be even better on ics... the best i had was ~2% per 8 hours...

3G + WiFi + email max 1 day

ICS battery life

Getting some great battery life on evervolv's ICS rom. Anyone else getting similar performance?
EDIT: Today im at 50% with 12 hours use... some tiny tower, about 20 mins of phone calls, gmail, google voice, and facebook sync

wow.. good for u.. my nexus one only last for about 15 hours.. btw, i'm using the medroidmod ics 1.4.0..

That's good. Might be a glitch though if your battery is not calibrated. I had an issue when my N1 was showing over 20% and then shut off. When I turned it back on, it showed 0% and turned itself off. Try to discharge it all the way and see it if will shut off before it hits 0%. I would do it as a precautionary measure just to make sure that your phone doesn't die unexpectedly when you need it most.

nice battery life mate

I have calibrated battery and it lasts around 12 hours with fairly good usage.
But my mobile shuts down when battery at 15 %.
Do I need to calibrate it again?

This will not help. I have calibratet again and again. I'm using the medroidmod ics 1.4.0.
My phone shuts down on 15%.

what are you guys using to calibrate for your battery? Mine used to turn off around 20-25% remaining but after I reset the battery stats its been more accurate. I get nowhere near the same amount of battery life that the OP has but I also am in a bad reception area.

I'm on the MeDroid HWA Mod and I cannot believe thatmy battery lasts for about two days now.
Do you really recalibrate or do you use the function out of your recovery, which function is busted meanwhile?!

Would like to find out about this battery calibration as well. Battery life on my N1 hasn't aged well, and I wonder if the batt's showin its age or something.

Mine isn't that good
I'm on latest MedroidMod but my battery drops fast with screen on and wifi but data off. It's like 20% each 25mins. But ICS is so sweet and cool that I don't wanna go back to the buttersmooth GB.
P/s: Which home launcher are you using/do you recommend to run on ICS?

My battery life seems to have improved slightly as well. I guess the complete redesign Google did, has done some good

wow its amazing

I'm running medroidmod remix and I'm happy when I make the day with one charge.
When my screen is on you can almost see my battery discharge.

With texice i had a huge drain (10% per hour), with medroid it was a little bit better but not nearly as good as with cm7.2RC1 now.
I've also finally updated radio to 5.08 yet.

58% at 12 hr's moderate usage on dk's rom (u5).

10.5 hours off power and at 63% on dk's ICS ROM. Screen time on is just over 1 hour.

Normally Ive never had a problem with the battery, ive lasted about a day and a half on moderate use, but with the latest version of BCM U5, when my phone goes idle for a while it starts to drop significantly, i'm not sure why its staying on other than I might have gotten a notification and it decided to stay awake

DK ICS latest update has a really awesome battery life, as well as a very good performance. recommended ROM 100% =)

Battery issues

Getting a bit fed with battery and thought I would see if anyone has any brainwaves on here, or whether my usage sounds about right.
I've been a bit stupid this morning and actually USED my phone. Been on battery for 38m. In car for 20mins with bluetooth connected, quick 2 min phone call. about half a dozen texts sent and facebook status updated with friendstream.
display = 54%
bluetooth = 11%
voice = 8%
wifi = 5% - although not connecting
android sys = 5%
dialer = 5%
android os = 3%
Idle = 3%
MessageCS = 2%
handscent SMS = 2%
Calendar 2%
Battery currently sat on 78% and regretting not bringing charger with me.
My missus Desire S in comparison, noticed last weekend on Saturday she was on 95% left. Asked when she last charged it and apparently it was Thursday!!! I lose 5% in 5mins if I try and do anything. She can sit there all night playing solitaire and use hardly any battery, mine would be dead if I tried the same.
So frustrating. Great phone just such bad bad battery unless just something on mine.

You can search in the DHD developpemnt thread there is some tips to get great battery

Would that be rooted though?

Yeah You Have To Root Your Phone

I rooted my phone, installed LeeDroid HD V5.1.1, still i just got 8 hours on the battery till it dropped to 10% .. i had an always ON EDGE connection with a few calls. Any suggestions?

You Should calibrate Your battery
install current widget from Market and battery calibration
once installed put on a screen the current widget and charge your phone and wait till the widget shows U 0ma then open battery calibration and calibrate your phone then unplug. try it the if the problem stills the same tell me

Just had quick look and I see there are 2 battery calibration apps, one by Nema and one by Professionals.
Which one are you suggesting?

the one for Nema

ah installed and says has to be rooted

Please charge your battery to 100%, boot your device in ClockworkMod Recovery and go to Advanced ---> Wipe Battery Stats.

ok does this mean needs to be rooted again?

Just did a Wipe battery stat and is waiting to see a diffrence.

It not always necessarily calibrating issue... You could try out different ROM or Radios...
I have seen good battery life with RCMix Blue energized edition... While sleep it gives you amazingly low battery drain.

Flashing radios involves a bit more risk I've read?
I checked on the terminal emulator, my ril does not match my radio.. can i flash the matching ril? Is the risk less as compared to flashing a new radio?

Just be careful, follow the instruction as explained in threads... I have done it a few times... They even say flashing is risky but that can't stop me, doing it in every 2-3 days.
Or you can go for AOSP ROM...

Pull the battery after shutting off the phone and then go do something else for a minute or two, put the battery back in.
I'd also advise getting better battery stats to check for partial wakelocks.

I'm sorry to say but you're wasting your time and effort. Root your DHD, surely its not still under warranty. With a root install an AOSP rom and run Juice Defender from market. Best thing id did.
Proof of concept.
