Hi!
I have installed CM10 nightly (ROM and kernel) from the CM website onto my wife's phone. Everything is fine except the battery consumption. I've purchased an absolutely fresh battery, and being removed from the socket around 08:00 the phone has to be charged already around 16:00.
Can someone recommend a ROM/kernel combo that will give a longer battery life?
I'm not asking which one is best, I just need one based on 4.1 which is stable and has a long battery life.

You have to try out yourself, because every person uses phone differently and thereby every phone uses battery juice differently.
On the phone off my girlfriend exactly the same problem....
Cyanogenmod the phone socks around 6% without being used. Also with fusion kernel or fax kernel
With CM10 and Fusion 5.4 I had excellent battery life...
Have you tried "wakelock detector" in order to find out if something keeps your phone awake? On my phone the only thing draining was Maps/Google Now, so if you want this feature it will drain battery at any JB Rom. Without it, I had battery for 1-2 days with 4h screen on time!

Dear all,
I have a EURO Desire Z.
When I use a Sense based ROMs (in fact, stock or Virtuous) I have a fairly nice battery life, that is, in the 30 hours range.
However, with any kind of CM6 or CM7 (or even Vilain ROMs), the battery life is really reduced. Like 12-15h max (almost without any use).
The battery monitor will show that most power is eaten by Cell Standby, Wifi and Bluetooth. I tried different radios, but the result is still the same. I also tried various CPU governor settings, but it didn't change the big picture.
Any idea on what may be wrong ?
I found that CM6.1.1 did that to me too, but reverting to 6.1 got me very good battery life. While I like the Sense widgets, I much prefer vanilla for everything else so i have't lived with a Sense rom long enough to see if it gets better battery life than CM6.1

I have the exact same issue as you with CM6 (retarded <12 hr battery life with light-moderate use). After seeing your post, I've decided to try a sense rom for myself. Will post results tonight or in a day.
Nope. Still drains like ****.
This may be teaching you to suck eggs, but are you recalibrating your battery after flashing a new ROM?
I found my battery life was immediately atrocious after flashing, until I completely drained the battery til phone wouldn't switch, then charge while switched off, until green light + a couple of hours. Then wipe battery stats in ClockworkMod.
After this, I found my battery life on CM 6 was really good.

No, I never did that. I'm not really familiar with the "battery calibration" stuff, but it sounds like something that will help to get good linearity in battery capacity estimation over time.
What I'm pretty sure, though, is that at some point (like 10-12h), the phone turns itself off. I believe that it has to do with insufficient voltage at battery terminals, rather than some sort of estimation of remaining capacity.
Or am I totally off ?
Hey guys, I am on cm 7 nightly #11. I am on radio 09.01 and have experimented with Chad's and the stock kernel.
I have background data, auto-sync, wifi, bluetooth, gps all off. I dont have facebook or anything pushing either. Screen brightness is on about 60%.
With the seido 1750 mah battery, I am getting around 7-8 hours of battery. That is to the bone dead .
That is making maybe 1 call a day, a couple dozen texts, browsing the web a bit and listening to an hour or so of music/pandora.
In spare parts it says under 'other usage'. Running 42.7%, screen on 23.8%. 'Partial wake' only ones on here are really music and pandora, but they are relatively small slivers.
Under settings it is 68% display, 8% cell standby, 7% voicecalls, 4% android, 4% idle.
I have tried wiping battery stats, doing the drain all the way technique, etc.
Anyone have any suggestion on what to do here?
Thanks.
I'h suggest moving to Cymod 7 RC1 (unless you mean the new nightly, then I'm not sure) I have been running cyanogenmod since before the nightlies hit and I've never had battery that bad. I get about 3 days of standby out of my phone on RC1 and the incredikernel. I listen to pandora on 3G (charging only in that time) about an hour a day and never charge otherwise unless I'm using it heavily. I text semi often, but don't really listen to music or call.
Seems wildly different that my experience. I take it this is specific to this rom, and your battery is better on others, ie battery itself not going south? With pretty similar usage and syncs to yours, I make it about 10 hours to use 50% of batt while at work. That's with stock battery. Only new nightly #8 with stock cm7 kernel.
1) change to 2.15 radio
2) did you buy the battery off ebay for $10? If so its really a 1250mAh or so. Either way OEM batteries are better than the aftermarket (ie Siedio)
3) Is the battery really old? If so it may be wearing down
4) Kernels are all decent, they should all get better than what you are getting...
5) Don't overclock to 1300+ it should run smooth at 998 or whatever it is.
I get 12+ hours of moderate use out of my OEM 1500mAh battery.
When I first started on the nightlies and flashing different kernels, I was having the same issue.
I stopped flashing other kernels and started using the stock cm7 kernel, now I am getting awesome battery life. Also, after flashing, several people recommend immediate rebooting to improve battery life.
Thanks guys.
Few questions.
1.) Radio 2.15? I am on 2.15.00.09.01 currently. Is that the same?
2.) Mine is an authentic Seido. But should I start using the OEM 1300mah battery?
Oh, I should mention. I don't overclock at all.
I was using the stock battery and got ~6 hours even with UC to ~850 most of the time and ~200 while screen off. Turns out my battery was defective and even now OCing to ~1100 most of the time I'm getting 4x the battery. Of course I couldn't be sure that my battery was defective until after I bought the new one but if the battery life just doesn't make sense then you might want to try going back to stock (assuming that's fine) and comparing.
try a different battery maybe
i currently have the stock battery which was only used a couple days
a HTC 1500 battery
a seido 1750 battery but i havent tried any of the other batteries in awhile but i also use CM7 nightlies on #11 because it seems to have best battery life
maybe ill try my other battiers and see my findings
I've had a similar experience and I'm fairly certain it was not my battery. The battery worked great with other ROM's; Normal usage of my phone would yield roughly 40% remaining battery life at the end of the day.
After going to CM7 (I started at #38) my battery has been lousy. I can't get through a day at all.
Two days ago I flashed incredikernel 2272011 as well as CM7 build #11. I'm using the default smartass governor and my battery performance is back where it used to be. Going through an entire day for me is no problem with normal usage.
Not sure if that helps but I've had good luck with this kernel thus far. Oh... and phone has been rock solid!
I'm on CM7 Nightly 11 right now with stock kernel. Seidio 1750 that I've had since last June. I've recently been comparing Tiamat's 3.14 to stock. If I'm on any kernel that has Smartass I'll use that as my governor. If I'm on the stock kernel then I use SetCPU with the kernel set to ondemand and a screen off profile set to 245. Either scenario seems to give me pretty good battery life, but I think Tiamat's with smartass may be a little better. With any kernel I've had it overclocked to 1.03.
Also, the brightness settings based off of HTC's ROM that were posted in the cm nightly thread in the development section have worked great. I've definitely noticed an increase in battery life.
I use advanced task manager with the shortcut on the desktop. I leave essentials running in the background but try to make sure everything else is killed.
All in all with the current setup I have I can get roughly 12-14 hours with heavy texting, 4-5 phone calls, internet and games scattered throughout the day.
Hi,
like the titel said, i experience huge batterydrain on CM7.2 RC2/133.
I am using the stock CM7 kernel that comes with the rom. I reflashed it several times but not much changed!
At first my device didn't go into deep sleep, but since the last reflash it does.
Over night i loose ~10% ... flightmode is activated.
After 1,5 day's the battery is empty... even if i dont use the phone. Wifi/3G/bluetooth etc. are allways OFF.
I also untervolted the device but nothing changed.
I am charging my battery at the moment, so i can't post any betterbatterystats log's. But i will in some hours!!
Basically my question is, which kernel do you use? What kernel can i use on CM7.2? Are there any better ROM's when it comes to batterylife/performace?
PS: i never flashed baseband or wifi modules etc. when i installed CM7.2... just did as it said in the "how to install CM7.2".
Try this.
1. Empty your battery.
2. Charge your battery for 6 - 8 hours.
3. After that remove battery stats.
I tried this as I'm having battery drain on NXT ROM. Before that my battery can only stand for one day then need to recharge. After doing this, my battery still have 50% after a day of usage.
Just saying, it has been confirmed that removing the battery stats does absolutely nothing.
so should i try another kernel? Which fits for CM7.2 best?

My friend taught me this lol. He even showed me a YouTube video.
Somehow it worked.

You really should upgrade to CM9 unless there is a reason you're holding back.
So im using cm10 nightlies and my epic 4g battery goes dead in a day with the phone off.
Ive done a cache wipe and flashed different nightlies and this still happens.
Is my battery borked?
Sounds like it.... while the battery will drain with the phone off it should be SUPER minimal, not dead without even turning the phone off... time for a new battery...
Yea Replace the battery and see what happens. You should be fine after
It's not the battery.
I reverted back to cm9 and the battery is fine when the phone is off.
The new kernel in cm9.1 and cm10 is screwy.

I hate to revive an old thread, but this is rather interesting. I bought an Epic 4G to use as a PMP/media device (Unified Remote rocks) and the battery life has always been rather dismal. Right now, I'm running CM10 stable and with the phone in Airplane mode and wifi off, the battery will drain 20% in 12 hours. The phone goes into deep sleep while the screen is off, but the battery still drains. In addition to all that, I've got a brand new battery in it.
The first ROM I flashed on the Epic? CM9.1. I'm starting to think that the issue lies there. Looks like I'm going to have to reflash and see what gives.

If u want good battery life, flash a gb rom... cm7 or tpr or any gb rom really... ics and jb roms are battery suckers...

I have the same issue. Just updated to CM10 release from CM9 release a couple days ago... battery life when the phone is on is about the same, maybe a bit worse, but...
The phone completely drains overnight after being turned off (powered down). Fully charged, off for 7-8 hours, completely discharged.
Would a later CM10 nightly or a CM10.1 preview be likely to fix this, or should I just return to CM9? Please advise.
Thanks,
khilts

This 1 million times! If you don't want a stock look or don't like TW go with CM7 the battery life ROCKS. If you like stock TPR ROCKS the battery as well. Don't forget this phone is NOT meant to run anything pass GB the fact it does is amazing but it will not be optimal for this device.
The issue for me isn't battery life when ON, it's the fact that the battery is drained when the phone is shut OFF.
Flashed the 12/21 experimental CM10.1 - problem gone, back to typical on/off battery drain rates.
A few months ago I had paranoid rom that was great on batt life. 3% loss from midnight till 6am.
I was blown away that I could use this phone so much and it hardly ever drain batt.
Kept telling me there was an update so I did and battery life went to hell...
Tried some others, Aokp and now liquid smooth. LOVE the Liquid smooth, but 25% over night is un-acceptable. this thing on the last few roms is constantly needing charged.
I tried restoring that one version of paranoid, but just wasnt the same.
so curious on suggestions on a better ROM or something.
There is no answer to this question. Different people have different preferences and experiences. If there was a ROM that was clearly better than the others, almost everyone would likely be running it.
Your best bet is to find out why your battery is draining. Use something like Better Battery Stats to figure out what apps may be draining your battery. Perhaps it is an app or two that is synchronizing a lot. Perhaps there are wakelocks.
Alternatively, it could also be hardware. Perhaps the battery is dying. Perhaps the USB port is having issues, and it wakes the device/screen up from time to time.
thanks cup... i just wiped and put that old one back on... will check it tonight. then ill put that better batts stats on.

You may want to start with trying a different kernel and see if that helps.
