I'm sure others have this issue: battery battery battery.
I'm on CM9 nightly (3-02-2012) with francos M1 kernel. Have not changed anything of the settings. have a pretty lean app collection. The problem is not the phone not going to deep sleep. The phone uses very little battery when screen off. My problem with this phone is when you have the screen on!!! As soon as I start using the phone for anything, the battery starts draining fast.
For example I unplugged the phone at 7 Am at 100% this morning and by 7:15 I had 91%. Turn the screen off and at 9:15 I have 89%. Is this some kind of battery programming thing or does this phone just eats battery when in use. I have the OEM extended battery.
CM7 did the same thing to my Nexus One. I lack the knowledge to know what in the stack was causing the problem. I'd guess something was tuned more for responsiveness than battery efficiency.
Or the fact that it's BETA.

I have poor battery life on my desire, it barely lasts 7 hours. I have tried wiping battery stats etc, and have the screen brightness at 50%. I have read that some kernels can greatly improve battery life, is this true? If so, which would you recommend, and do I just flash it like I would a rom? I am using the latest miui.
Cheers,
Steve

They can but finding the underlying app causing the phone not to sleep would be what I'd be looking at. Remove all installed apps and add them 1 at a time and see how the battery goes

Yeah i've tried this, there's nothing draining the battery.
Not at all
Such battery drainage can only be induced by either heavy usage, or phone not being able to go to sleep.
The differences between kernels in custom roms are merely a shades since all of them are pretty much battery efficient. You won't miraculously jump from battery life of 7 hours to 30 hours. Concentrate on your apps or even better, third party Widgets.

Probably a hardware fault then - the OS on it's own with no apps installed shouldn't drain a battery that quickly. Did you also turn off the sync options to test that theory?
Personally sounds like a knackered battery/phone
If it isn't apps/widgets (they are the culprit for heavy usage) then it would prob be a faulty battery. I did a little test last month to see how much battery I could lose in 24 hours. I lost 8%. I guess it could be a baseline to start off with.
Last straw was last night. Had 13% battery life left before softball last night and knowing I wouldn't use my phone during the games, but having been burned by my battery before, I shut my phone down before the games. Played softball for two hours then turned my phone on. Booted up long enough to see that I had 0% battery before it shut down again.
What am I doing that's causing this? I get maybe 10 hours out of a Seido 1750mAh battery. I have no apps that do background updates. I keep my display on "dim" most of the day. I go most days without even making or receiving a single phone call!
Ideas? Thanks for any help. This is really frustrating.
Cyanogen Mod 7.0.3
Kernel: 2.6.37.4-cyanogenmod+ [email protected] #27
Baseband: 2.05.00.06.11
Seido 1750 mAh battery
I'm not sure, but there have been claims that Seidio inflates their numbers and their 1750 mah battery isn't actually that much. Has this been something that has been happening gradually? Like your battery life is degrading over time and now it's at an unbearable point?
Try a different Kernel or Baseband. I'm using MIUI w/ incredikernel and get great battery life w/ stock battery. I'm also using 2.15.00.07.28 Baseband. I use SetCPU to set a screen off profile of 245min 245max, havn't noticed any lag while having that set. If you wish to update your radio easily you could download "Inc Bits" from the market. Great app has all of our phone radios, all you need to do is rename it and move to SDcard.
Agree with tcberg2010 here. Try incredikernal with Smartass governor. Check out vipermod. I was having intense battery issues which i posted about a week back. My suggestion would be to get spare parts app and check partial wakelock to see if anything is keeping your phone up. I use maps occasionally and it turns out that it was causing partial wakelock constantly. After disabling a locations and gps i am back to standard battery life. Looking forward to next cyanogenmod update, hope there is a fix...
If your phone died while it was turned off, then I would either have battery tested or get another one it could have an internal problem.
Yeah unless the phone some how got turned on in your pocket (I'm not sure how, but it has happened to me), There should be minute if not no drain on the bat at all. I'm not sure where you can get it tested, but I would certainly be wary about that bat. Do you still have the stock 1300? I'd check to see if it looses charge while the phone is off. Maybe there's a short in the phone.
Thanks for all the suggestions. I'm at about 10.5 hours right now and 7% left with the only thing I've changed being the battery. I went back to my stock battery. Going to try a new radio first, then vipermod.
try the "battery moniter widget" from the market. it keeps perfect tabs on your battery, can tell you the REAL mA of your battery, temp, usage stats, all kinds of stuff. it's really a good app to use to watch your battery...you could also use MIUI, and watch your battery life almost double. it's superior to CM7 in so many ways. and the people that have used both, i think pretty much agree...
I switched to jellybean (android 4.1) recently. The system is great. However it drains the battery much more than cm7. During a night the battery can reduce from 80 to 60. Is it normal? If not is there solution to extend battery usage?
Unfortunately, that is normal. Turning the fire off can save the battery, but I just charge it everyday. Compared to rooted stock, battery usage increases between 10 and 20 percent for me under normal use.

According to Better battery stats, most of the drain on my Kindle is caused by AudioOut2 wakelock. I failed to resolve the issue and i'm not sure what is causing it. I would like to know if anyone else experienced similar issues.
IMHO, it must be sort of a bug since JB is fairly new and devs need time to resolve all the issues.

Same exact issues here. And I agree that it will (hopefully) get ironed out over time.

I don't seem to seem that terrible of battery life with mine. I'm running twa_priv's cm10 and during the night it might go down about 7-10 percent. I do have Wi-Fi off while in sleep which helps.

That's not normal for a standby... it should be <5% ...not the mention that device does not have to communicate with 2G/3G networks (unlike smartphones), and on my smartphone i get average of about 3days (medium usage, light on wifi) without recharging
It's a bug - some process prevents device to go to sleep (aka. wakelock) which causes drain. I expected at least 2-3 days on a single battery charge, and tbh, recharging it daily is little bit disappointing Something tells me it's a kernel bug since i encountered it on every CM10 rom so far :S

Well coming from an previous ICS build it's a major improvement. Typically the battery life from ICS builds(That I used, Energyrom, AOKP Kindle Edition, GedeRom) would drain 20-30% nightly like the OP said, so coming from there it seems like JB fixed whatever was killing the battery. I can probably go a week with light usage on my kindle before I recharge it. ICS in general drains the battery on any device. I used to get 5 days on my Droid 1 running CM7. With ICS I'll go through 3, though I never want to go back to Gingerbread, hahahaha.

My record for battery on a smartphone is 6 days... using ICS
Anything that drains battery more than 1% in 1.5/2 hours in standby is bad, no matter what OS version...
I also have the impression that on a fully working Jellybean ROM, battery usage is more intense than on a stock ROM. I still prefer the advantages of the new ROM, and also charge daily. Being mobile, I use the XTPower MP-10000 Powerbank, which gives more than enough battery life and charges the kindle while in use to 100% full. This has resolved the issue of battery drainage for me.
I don't know what is causing this issue in my Samsung Galaxy Nexus, it's a kernel problem? Any ideas? Suggestions? How to extend a bit more my battery since it drains in 2 or 3 hours as maximum (see the attached images for more info)
Is your device supposed to be idle during this period of time? If so, then perhaps you have the USB port issue, which one of it's symptoms could be phantom charging. Phantom charging basically means that the device thinks it is charging which turns the screen on and also keeps the device awake.

Maybe but I'm not so sure since phone screen is off, maybe another things, any application or CM issue?

It seems its awake most of the time.. I think there is an app waking your device..

same issue
I have the same issue. I was on the stable release and the battery drain was terrible. I went from all day battery life to about 6 hours or so. I updated to the nightly builds hoping it would fix it. Still terrible battery life. I have pretty idle usage too. Any ideas?
I was having issues with the battery life on nightlies until the snapshot hit at the end of last month. Then it drastically jumped to better battery life for me. It's been much better since then on the nightlies.
I do have a battery-chugging app (pedometer), but even with that, the battery life went dramatically up after the snapshot.
magical fix
Gave it a full charge and updated and the issue is gone. got great battery life the other day.
I barely got this tablet yesterday and already seeing fast battery drain. I don't have that much apps/games. I rooted it today in the afternoon but I don't think it will drain the battery.... What's the deal here?
This is my 10.1

There's always an initial drain that is rather fast due to the fact that the charging is not perfectly optimized, notably while it's new. Even though it says 100% it's most likely not the fact. On the other hand due to the large screen the screen uses a lot of power. When using Cyanogen for maybe 20-30 min/day I'm still at 97% the next morning w/o charging. But, I use a lot of mods and settings trying to optimize battery usage. Once you get used to the device and start experimenting with ROM's, settings, mods I'm sure you will find a way to optimize it to your flavor.
The tablet has to scan all directories for media.
Here are some really good tips. You can also shut off a lot of samsung bloatware. I have probably 50 things shut off along with below tips I get amazing battery life and never any lag. Not a fan of magazine touchwiz so using nova and couldn't be happier.

For a new device, you need to cycle the battery to about 10%, then fully charge, to set the battery meter "high" and "low" flags (some call this "calibrating the battery meter"), before you can expect the battery meter readings to be anywhere accurate.
