I have not changed anything... I was getting 16+hours and still having between 15 and 20% left but the last two days I'm hardly getting 10 hours! WTF!
What is a good program for seeing what apps are open when they don't need to be? Would that just be like a tast killer?
Just a little rant... sorry. When I complain to my friends they just call me a nerd... I need to vent to people that understand, haha.
does your ranting require a new thread?
Wow people, how on earth do you guys get battery life of 16hrs. I can hardly get 3 hours on my phone...

Yeah, Its as pointless and useless as your post. Yet we both wanted to say something... so here we both are... wasting space.

you using the phone for straight 3 hours? if yes that's normal.
To the OP check the new apps you've downloaded.

Nope.. I use it moderately. listening to music for maybe an hour brings down my battery levels from 90 to 58% and this thing is draining 1% every 2 mins on standby...
Btw while I was charging my phone and it magically jumped from 8 to 34% in jus 10mins or so(I had switched it off before charging and after few mins of charging, I switched it on to find it on 34%). Is this a factor??
that's ridiculous, that must be an application eating up type battery

jumping percentage means your battery stats is ruined. wipe it, but the battery drain on idle mode isn't about the stats.

If you're charging via USB, you may wish to connect to AC. USB doesn't charge as fast and your phone (apps running, etc) may using power faster than the USB can replenish it.
If you're on AC, turn the phone off and charge it that way. If it continues to decrease this way, there is something seriously weird with your device.
I re-flashed bionix but the battery drain still continues.. Should I change back to toxic darky 9.5 and see how the battery on that thing is working?

So I have seen a couple users asking about creating a new thread for battery life on CM7 only, so here it is. I am getting ok battery life, but nothing near where it should be.
Here is where you can suggest, try, try again, and submit findings pertaining to the battery life. So let's get this started!!

I've found that turning off the radio saves battery life so I def. think that the radio is the problem for it
Thanks for starting this. It should be interesting to see where this thread goes.....
You mean flight mode? I don't think that is a viable solution, well at least if you need to use the phone. I can't even get xda super power installed for some reason

I get better battery life with KB5 too.
I can confirm that data use is probably part of the issue. I live in the sticks, there is no 3G at my house. My battery life is actually descent, no where near what I had with Froyo, but it doesn't seem to be anywhere near as bad as other people are claiming.
turn off background data when you don't need it, don't use auto brightness.

Personally, I've just read from some ROM thread here, that you need to calibrate your battery if you flash custom ROMS. So far, it has worked out quite nicely.

Yes, also doing that. I recommend to go to the Android Market and search for Battery Calibration by NeMa. It's a great, free application as well to make sure that your battery is calibrated on top of the instruction from the quote.
Using spare parts app change wifi sleep policy to never. Known bug in gingerbread. New wifi drivers were just released for stock builds but I don't know if theyll work on cm7 or if they will be implemented.

Ya battery calibration app works quite well, that is something I haven't done yet with this ROM 0_o
I was having terrible, absolutely terrible battery life with CM7 and I decided to do some investigating. On my initial installation I used Titanium backup and Google Backup to restore settings and applications. I could not manage 4-6 hours on a single charge, with calibration.
I decided to do a fresh CM7 install to test things out. I simply booted into recovery and wiped data, cache, and system. I reinstalled the initial package provided on the CM forums and let CM7 boot. After letting the new installation settle down for 10 minutes, I rebooted into recovery, flashed gapps, and then the newest nightly. Again, I let it boot and sit for 10 minutes before performing anything. After settling down, I charged up to 100%, rebooted into recovery again, and wiped battery stats.
I should note that through this I declined google's offer to use backup services and declines google's offer to restore any old backups. I also decided to not restore any apps through titanium backup.
With my screen brightness set to 100%, wifi enabled, bluetooth enabled, and using the phone at amoderate to heavy amount, I have gone 12 hours and am at 5%. I am certain that after the battery stats can calibrate fully and run through a few more charges I will easily hit 15 hours on moderate to heavy usage.

if you have rom manager pro the nightlies are available for download.
here's a few tips for you guys:
1. turn off 3G, stick to GSM only. Found in settings > wifi and network > mobile network> gsm only
2. use some black themes, anything than the normal grey and stuff should help
3. If you have data, use that instead of wifi, from what I see wifi eats more battery
4. if you're using wifi, go into wifi settings > *menu button* > advanced wifi settings > wifi sleep policy to: when screen turns off or never when plugged in.
hope that helps
This thread has been very helpful. Thanks

Hmm what if I'm flashing total stock, no cwm/cf root or anything?
Without root you can't use the battery calibration app as well, so you can't wipe
May be the battery will calibrate itself after a couple of charge\discharge cycles.

i wipe stats after a rom flash i am sure the devs and community didnt make it up for no reason
Not much point unless your battery stats file is full of inaccurate information. No worry since you can't do it on a non-rooted phone anyway. Give enough charge cycles, the information in the battery stats file eventually works out to be something reasonable even if it started out with inaccurate stats.
how to wipe that battery stats...plz some info
U generally don't have to wipe the battery stats....n never let ur phone full dischared, charge ur phone whenever u get the time.
Fully charge and discharge it once in like 2-3 months to recaliberate it.

Nope, I dont see the point in wiping the battery history, contrary to the popular belief that battery stats is the current running calibration data
its there for a reason.. you think the devs are dumb?
flashing it makes it much more accurate.
I always wipe the battery stats after flashing a new custom rom.
I think this is especially important if you don't flash at 100% battery.

Hi there,
You haven't given much detail on your upgrade
But assuming you flashed a ROM, did you also flash the recommended radio?
If you did do both, give it a couple of days to settle down (try to resist the temptation to fill the phone back up with apps), then compare again.

What type of battery performance are you getting?
Check this. It helped me out alot. Improved my battery life alot.
Just go by instructions on how to flash the ROM properly (recommended). When you boot up the ROM for the first time just install "Current Widget" from market and "Battery Calibration". Plug the phone into the wall or computer and leave it to charge till 100%. Then just open the "Battery Calibration" app and calibrate the battery. Read more in the thread.

OK take a look at what your battery info says is killing your battery. There are alot of things that can effect the battery. When you did the update did you do a factory reset? What apps do you have running? Social networking Widgets updating?
this thread is stupid. you say you have crap battery, yet you fail to deliver any statitic, screenshots, usage etc.
4 hours what? standby? screen on time?

Dear 6696,
Pls go easy on me. Since the upgrade i did not do the reset for fear of loosing my settings and Apps. Simply said prior to the upgrade i spent 8 to 10 hrs with my phone doing everything and that includes listening to radio, surfing the net and making calls but after the upgrade it takes only four hrs doing same to finish the battery. Thanks.

Google Maps was a massive battery drain for me. Try using the Sense Task Manager to kill the app for the time being and see if that helps at all.
Also Twitter (the official app) seems to be using a lot of battery too.
Whenever I leave my phone charged overnight, I wake up to around 70% charged. It's as though once it reaches 100%, it stops "charging" and it starts using the battery's energy, rather than the AC. Any help?

go here http://forum.xda-developers.com/showthread.php?t=1238070 and follow step 2, then go to http://forum.xda-developers.com/showthread.php?t=1459905 readthrough the first part on TW kernels, choose one of the 3 custom kernels (not the stock one), best advice is to read the op of each one and find one you think will work for you. they are all three well written kernels. one is already oc'd to 1200, which means no need for voltage control if you plan to oc your phone. most phones are stable at 1200 but thats just from doing alot of messing around and odining. the second post is the instructions for flashing the kernel. the first post just explains all of them to the best i could w/o kanging any information from the op. i just ran what i knew off memory. links to each kernel's op are at the bottom of post 1. i did links to the op's instead of posting dropbox files due to the fact that I want people to make sure they know what features each kernel has before they download it.

They are essentially the same thing. Battery Calibration is wiping the battery stats and running the phone dead than fully recharging.
I have been having a very similar issue. A buddy of mine (captivate) and I found that the phone wont charge past 98% on CyanogenMod with the Glitch kernel. I set the phone to not lock and keep the screen on while charging and the problem went away. The phone also would not stay on A/C power after reaching 98%. This issue was fixed too.
I think its an inherent problem with the batteries on the phones, since the issue occurs on many different roms/kernels/phones.
whether it's caused by the phone, ROM, or kennel, battery calibrator is a simple app that is at least worth a try in my opinion
