Here are the settings I'm running on CM7 to get amazingly bananas battery life (with the display being on for about 5 hours!)..
1. Conservative governor: 245mhz - 1017mhz in CM7 settings
2. Install the 'BatteryCalibration' app from the market. This app caused the single biggest improvement for me after having flashed so many roms and never calibrating the battery. If you've calibrated it before though, I don't think it'll be very useful for you.
3. Install 'NoBars' from the market to automatically turn on airplane mode when you have no service. (This might be useless to some of you if you always have a signal; Very useful in NYC subway though)
4. Use a 2G toggle widget to have the phone only use the Edge connection when you only need it to receive calls/ texts and don't need the high speeds. I use the toggle widget in the CM7 notification bar. HUGE battery saver.
Give these a shot and let us know how they work for you
I've reached the end of my day and here are my final stats..
Mmy display has been on on over 5 hours now and I have 5% of the battery left. Seems more than good enough for me. Hopefully it will be for some of you too
Edit - Updated with more recent stats

Question: It's cool that your display was on for 3 hours, but what did you do as far as app usage??
If you did use your phone "a heck of a lot" wouldn't some apps like "internet" "maps" or something show up on the battery use %'s???
For example, currently, other than phone idle, cell standby, voice calls and android, there's also internet, mail, maps, and other apps that I used today alot.
Good observation. I have no idea how android chooses which apps to show on there, but I think it depends on the ROM? I remember on Iced Glacier cell standby would barely use 5% of the battery and on CM7 it uses >40% consistently. Idk.
Maybe what those apps used up here was nothing compared to the display, wifi and phone idle time.. Just a guess.. But I did use the browser and xda app and listened to music via the Rdio app running in the background several times throughout the day, and sent multiple texts and have had my wifi on for about 5 hours now. I can't really find a menu that would show these statistics except in the Spare Parts app, and here you go..
I got 17 hours just yesterday with 9% left with moderate to heavy use (texting, web browsing and ps1 emulation).
I didn't do anything besides use faux's kernel with the smartass govenor. I have the max speed overclocked to 1.8 as well...
Nice. I just got over flashing new kernels for a while since the stock CM7 one has everything functioning perfectly and new kernels would improve on something but mess up something else in my experience.
I can't seem to find a 2g toggle widget that works with Royal Glacier. (one touch, I've found a few that take you to settings) When I was running Royal Ginger I would always use the one that came in the notification bar.
Wifi status is also a good app to remind the forgetful to turn off wifi when they leave the Area.

This is GREAT battery life... i wonder what word i'd use to describe mine.
i Pulled my Phone off the Charger this morning @ 7:20pm EST. Now it is 3:13 EST. and i've got ~50% left. So thats what like. 7 hours
neidlinger tap that 'screen on' tab and lets see how long your screen was actually on for?
Either way congrats, and it's good to see ppl are over the battery issues.

since my last boot. 8:10AM when i loaded the new CM7. 1h 1m 59s.
Unless I'm missing something, the 'BatteryCalibration' app won't increase your battery life. It will just help to get a more accurate reading of your battery level.
I've played around with different roms and kernels. And yes, they do have a small effect on battery life, but not all that much.
Here's my tip for battery life. Get on ebay and buy one the of the cheap packages from Hong Kong with 3 batteries and a standalone charger. Like this:
http://cgi.ebay.com/3x-New-1500mAh-Battery-Charger-HTC-Mytouch-4G-Merge-/290556738794?pt=PDA_Accessories&hash=item43a687fcea
I bought a similar package a few months ago and now I never have battery problems. Nor do I have to take a chance on wearing out my micro-usb jack like I've seen happen on a lot of other phones.
Maybe. All I know is my battery increased dramatically after running that app once.
I measure battery life by how many hours I am able to keep my display on before it dies rather than how long after it comes off the charger (like nedilinger does). My battery used to die after about 3 hours of the display being on. Now it consistently lasts 5 hours.
Anyway, I was just trying to let others know what I did to get a really good battery life on my phone thinking it might be helpful. Apparently that's not appreciated. Thanks tho.

simple way to get awesome battery life without any extra steps is to install RoyalGlacier 1.6, that's all. A couple days ago I ran my phone for one and a half days before charging it again, and it still had 14% battery left. RG is pretty much a polished version of CM7, runs blazing fast and smooth.

Better than what's reported under CM7. The battery life I posted above was on RG.
you say you don't sacrifice 4g but you admit you have a 2g/edge widget?
To me "not sacrificing 4g" means not ever turning it off, maybe i'm mistaken
I had battery issues, I'd have to charge it mid day else it would die. Juicedefender helped a bit (claimed to do 1.7x battery life) but I uninstalled it, rooted the phone, and uninstalled a bunch of stock apps
For some reason now my battery lasts a very very long time, don't know how or why that is. I also admit I don't use it as heavily as some people, but my habits have not changed and I did have to charge it mid day (like i said) even with little usage

Obviously, it's hard to say without describing how I use my phone, but I get probably 10-15 hours of medium-high usage. I probably get about 4-5 hours of talk time. I'd say the Chinese ebay batteries probably last 80-90% as long as the OEM battery. Quite decent considering the price.
My earlier thoughts about the BatteryCalibration app could be wrong. I don't really know all the details about how Android battery calibration works. I just assumed that it simply learns about all the bad spots in your battery so that your phone doesn't instantly jump from 80% to 30%. I also assumed that the phone would die when the battery had no power left, as opposed to when it says 0%, but maybe that's not the case. Regardless, if it helps you, more power to you and I appreciate you sharing the app. I didn't mean to come off as an unappreciative ****. If I did, sorry bout that.
I am loving this rom, but also having HORRID battery life, I am literally dropping 10% every 90 minutes with an extended battery.
27% Cell Standbye
26% Bluetooth
19% Display
Now I keep reading that these might be false readings, but I keep reading this as a response to those having **** for battery life... so maybe they are not false?
Anyone having good battery life show readings like this? Those with bad battery life, what are your readings?
I'm running the CM7 w/the 2.5 radio - I'm in a 100% full time 4G area, but seem to have worse battery life when the 4G radio is on, so I just keep the phone on 3G - if I need the faster data I can always turn it on and off.
I'm running the stock kernal, no overclocking or setcpu type stuff going on.
Would like to hear from folks running this ROM w/killer battery life, what are your settings, tweaks, etc. Please specify if you're running an MR1 or Mr2/2.5 version and/or running the latest OTA 2 radio that just came out like yesterday.
I just turned off my FB sync (I forgot about that). I don't have gmail set up to sync automatically either.
I'm going to do this procedure a little later today and see if it helps, this is for the EVO, but, ya know....
34. "Calibrate" battery - (1) Turn device ON, charge it for 8 hours (or until LED turns green), (2) unplug and turn it OFF, plug it back in and charge for 1 hour (or until LED turns green), (3) unplug and turn it ON, wait 2 minutes, turn it OFF, plug it back in, and charge for 1 hour (or until LED turns green), (4) unplug it, turn it ON, and use normally.
Anybody else try this?
today will be my first full day of work use w/this ROM so we'll see what happens.
Best to keep 4g off if not using it. Also, turn Bluetooth off when not in use.

i had horrible battery life the first day - then it got better. then i flashed mr2 official and battery life is really solid. getting like 15-20 hrs with 4g always on, bluetooth on sometimes. one important thing is having a custom lighting table which i will post later.

I have never, nor do I intend to ever do this. I got an extended battery for a reason. I can go all day and then some on the official roms, and all of the Sense roms.
I am not new to CM7, I have run it on both an Eris, and an Incredible. Both devices got FAR better battery life on CM7.
I am not complaining about this rom, or Slayhers hard work. I simply want to gather information so that we may help him trouble shoot.

This is exactly what I did lol, I had lost 10% in the first 90 minutes, now I am at 58% at 5 hours. I have been streaming google music for 2 hours of that 5 though. I would guess I should have seen an increase in battery usage, but have not.
The battery readings are wrong, I get a full day on 4G with my stock battery and see those numbers for cell standby etc. I use lean kernel though
Sent from my ThunderBolt using XDA Premium App
do you see those numbers for BLUE TOOTH though? We know good and well some numbers are fake, but that does not mean all.
FYI I am now at 37% and 7 hours and 7 minutes... I have not used google music since the last post and I am seeing the exact same battery drain as when I was using it.
I have absolutely horrible battery life when I'm at work (which is basically a bunker). On a normal day, my battery will be dead within 6 hours just sitting there on my desk.
However, when I am at home (great 4G signal), I see my device getting upwards of 16 hours with moderate use.
I will also say that since I upgraded to the most recent radio, I have been having much better battery life at home. Additionally, my phone has stayed much cooler with the most recent RC + new radio combination.
I heard if you change the render fx to n1 calibrated, then you will get like 1 hour extra of battery life. You can change the render fx by going to cyanogenmod settings.
11h32m11s on extended battery 69% left
The other numbers have to be wrong. Theres no way cell standby is the number one battery user.
my cell standby is also showing 30% with the new OTA 2 radio.
I switched to dream kernel (have not wiped battery stats) and am now at 88% after two hours, that puts me at 6% per hour verses yesterdays 10.

only works for AMOLED screens.
edit: to be clear, it only saves battery on AMOLED.
so what i have found is that after installing dream kernel and messing with the governor settings... along with being connected to wifi. my battery life has improved tremendously. i wiped battery stats this morning after a full charge and didnt notice any change.. then i flashed the kernel and messed with gov. settings... after rebooting ive noticed a huge huge difference.. just my 2 cents for anyone who had battery issues like me
Yesterday I was able to choke out 20 hours while in a 4G area the entire time.
Running RC 1.2, Imoseyon's leanKernel extreme mode (extremely undervolted and OCd to 1.4GHz) and using the InteractiveX governor.
Also, I just happened to reboot and surprisingly it only took away 1% of my battery. Amazing considering whenever I did that on a Sense ROM, I'd experience a battery loss ranging from 7%-10%.

What settings did you land on as best?
cpu is set max to 368 mhz(very low) but i can crank it up if im doing somethign like playing games or downloading and want speed. brightness is at about 15-20 percent. the dream kernel and mr2.0 radio have made a big diff too. the dream kernel made the biggest. usually when id power off or reboot id lose 6-10 percent same as someone else i saw post. now i lose maybe 1 percent which is a huuuuge difference considering you lose 10 percent just because you reboot. also i try to stay on wifi wherever i go. on 3g i def notice it drain quicker, but i am no expert and there are a lot of people on here who by far outexperience and outknowledge me(my new 2 words) so im sure other people have some suggestions

That is strange I am also using CM7 with an extended battery and still have 41% left after 14:56 on battery.
battery use does show
cell standby 31%
phone idle 19%
android system 19%
wifi 11%
dialer 10%
display 6%
voice calls 3%
So here's a screen grab of my phone's battery. I work 9-5. Started the day with fully charged battery, and end of work day it's almost dead. Honestly, I never thought it would be this bad. I don't play games or watch endless videos on youtube. I've sent about 15 texts messages max, used the phone to make about 4 calls for a max talk time of 6min. And browsed the net for no longer than 5min. I have wifi always off, GPS off, my screen is always set right down to absolute minimum all the time. I have never used live wallpaper, and have a black wallpaper. All I've done to this phone is root it and remove a lot of bloatware. Nothing else. I've read through the forum and came upon this thread:
http://forum.xda-developers.com/showthread.php?t=1092249
So without running the Bali kernel or running any specific rom, Is this the expected battery life for the average person who just leaves the phone completely stock.
*UPDATE*
JuiceDefender works!!! Battery now last much longer. Thanks goes to jager555 for the great suggestion.
Most high end ones are. because android runs things in the background and allows you to customize many settings, Battery life usually looks like that when you first get your phone. That said once you get familiar with your phone you will start to recognize things that run in the background that serve you no purpose and you can stop them or get rid of that app. You can also get custom roms that have great modifications to enhance your battery's life. It takes some experimentation but gone are the days of getting 4 days out of you Razr. Try searching "battery saver" in the market, too.
It could look like this...
Well I have to say that's quite shocking. The average person just has no clue on how to flash roms or anything like it. They just charge their phone and go. It really makes me wonder why Google or the phone manufacturers wouldn't think battery life to be a priority. The battery life isn't just bad, its unacceptably bad.
Thanks for the input though.
Yeah no thats not normal. When i first got this phone i could go up to twelve hours non stop with regular use text here and make some phone calls, watch one or two videos... And i still had battery left probably like 40% maybe less. Well at least for me i dont know if i was a special case or not.

if you are on stock and do not use the bali kernel, get Juice Defender from the market. try it out for 2 days and get back to me on how it works. if you want the best battery life, especially since you take off gps and wifi, set it to aggressive. that should make the battery last MUCH longer with your type of usage. but once again, use it for 2-3 days for it to settle in properly

yea, my dad is on stock with this phone and it wouldnt last from 7am to 2pm. now it lasts from 7am to at least 8pm with the same type of usage. its a neat program. i hope it works well for you.
I'll second juice defender. Even the free beta version has helped my phone last a long time. but if you aren't using your phone much, you should really get a lot better battery life than that. if it's brand new, it can take the battery a couple of charges from a full drain to get up to snuff.
With light use, I can get well over 2 days, and have even gotten over 3. Here's a screenshot I took a couple of weeks ago.
mike-y was the one who introduced me to juice defender, btw. great find, man
Wow, Tempott, that's very short battery life. I actually had pretty decent battery life on stock. I lasted about 12 hours on moderate use. Then again, it's funny that I last 18 hours on very heavy use now with ICBINB with 4G on, first level brightness, and sync always on (no JuiceDefender, etc.).
i am using Audiophile ROM. i get 10-15h of battery life.
Im using black ice with bali 3.1uv dsexton's build.prop and im getting round 12-15 with heavy use(mobile AP, pandora, calls)

Sorry for the late reply, but I just wanted to give the app a thorough usage. I'm happy to say it really makes a difference. I was so disappointed with the battery life that I had a serious bout of buyer's remorse. This App made a world of difference. Thanks for the suggestion! Glad to have this phone now. Check out the screen shot!
Nice!! that's great. I liked the beta app so much I went ahead and paid for the "plus" version. "Plus" gives JD control over wifi, and lets you set a "night mode" that turns off data/wifi/gps/bluetooth during the night when you sleep. There is also app control, which I played with, but ended up just disabling it (makes things a lot simpler).
Honestly, if the beta is working for you, there isn't much need for the paid versions. especially if you put your phone in airplane mode when you got to sleep (or just turn it off).
btw, current uptime = 40 hours, 45 mins, and I still have 70% battery left.
It seems to me Battery Calibration doesn't work...however, this phone lasts longer than the Sensation, which personally sucks.
battery calibration works fine. make sure your phone is charged to 100%. check spare parts amd make sure it is at 4200mV. sometimes, if it is not calibrated properly, it will show 100% and not 4200. unplug the phone and immediately plug it back in and you will notice a fluctuation in the numbers. usually, it is a big fluctuation. once you are as close to 4200 as you think you are going to get while the phone is plugged in, open the battery calibration app and click calibrate. then immediately unplug the phone. use it until it is completely dead (i do it until i shuts down). once this is done, charge the phone until it is 100%. do no unplug the phone until it is at 100%. then drain it again. and charge it to 100% again. after that, use it normally for 2 to 3 days and you will notice the difference in efficiency.

I would like to add that the first charge drains amazingly fast. You can be idling your phone the whole day, and it'll still be gone.
After you go through a few charges, it'll be omgwtfbbqhax battery life.
Btw, I'm betting Bali 3.3UV + JD is pretty beast battery life compared to Bali 3.3 + JD, right?
Juice defender works great for me as well! Very noticeable difference
What do you guys do to maximize your battery life? I just can't seem to get decent life. Average is probably 5 hours with heavy usage.
Any recommendations?

The usual - brightness as low as you can stand, radios not in use turned off, screen timeout 15 seconds, 200-1400 conservative governor in SetCPU.
Search AutoKiller in the market -- choose "optimal" profile, so far has given me an extra two hours today over what I got yesterday.
5h of heavy use is good already.
You can tweak your idle batt life, 2g-only, undervolted kernel, avoiding power hungry rom.
Idle battery life is just amazing with stock... just test it over night, 6hrs get 2/3% for me.
I can get 30hrs with 4hrs with screen on, the screen is the key here, i can get 5hrs with 4hrs with screen on too. ;o)

How would you define "heavy" usage?
Also, what does your "battery use" stats say? (Settings - About Phone - Battery Use)
5 hours of truly heavy usage (online gaming, for instance) is actually to be expected.

You can create a custom prl setting. Turn wifi to never sleep when you're at home... Have the prl to auto *CDMA or GSM* Which ever your network is on. (This goes to all Nexus S. users). So you have wifi on with a signal and 3g off. The phone stays in 2g for calls and uses wifi for data. Turn off google location services while your at home, turn off roaming, turn all of that off. I get about 13 hours of battery life with heavy usage. People think wifi drains your battery but it doesn't if you have mobile data turned off. When you have 3g turned on it's constantly searching for a better connection. If you have wifi on and a strong connection it isn't constantly polling.
are there any charging habits that would help prolong battery life? I usually just charge my phone every night cause, if I remember correctly, these batteries don't have a memory or anything. anyone know if that is the smartest thing to do?

I hope you don't mean overnight. I don't know if phones have auto-cutoff feature (a la laptops), but it's safer just not to charge overnight.
I personally use an extension that has a timer built-in. Nifty. Set the timer, plug the phone in, it will automatically start and stop the charging at the predetermined times. I usually time the charging to end right before I wake up, so the battery doesn't stay fully charged for too long. I heard batteries corrode faster when they're fully charged.
When my battery life starts getting shorter than usual, I let them drain until the phone turns off automatically (well I actually try not to get to that point, but seldom succeeded ), and as soon as possible charge it until full.
Usually the battery holds longer then. It has something to do with teaching the battery about the true empty and true full.. or something.....
AFAIK. CMIIW.
doesn't the nexus s have a built in cut-off feature so it will only charge to 95% though? I figure that would take care of the full charge issue. i'm also not sure if lithium ion batteries have a memory, but you could always reset the battery stats if you're on root to compensate for the whole draining and fully charging thing.

I don't know what would happen when the cut-off feature kicks up. My Nexus S still shows a charging icon even a while after full, so I don't wanna risk it.
The best way is by touching the charger unit after a while and see if it's warm/hot. If it is, it's still charging. But you gotta give it time to cool down first (after it's finished charging) Haven't gotten around to it, though. Always forgot to check the charger

lol, I know that my phone for sure won't charge to 100% from watching it, so even after a night of charging it's still at 95%. I've read a few explanations on this forum about the whole not fully charging thing too, so i'm pretty sure that it's like that on purpose.
my lg g2x drains my battery when turned off
the most previous experience was last night when i had my battery at 39 percent when i turned it off the next morning when i turned it on it was at 19%...
At first i thought it was the faux's DebouchedSloth (the one with the funky readings) so i paid no mind to it. (i just left it on during the night in airplane mode, which actually gave me better battery life) Later, i flashed the trinity kernel, only to find out the same thing happens
what do i do?
im running the latest cm7 kang build from baldwinguy77 with trinity kernel T15max 20122011 if thats any help.
thanks in advance
try a "battery calibration"
let it drain out completely and then let it charge 1 to 2 hours extra after it has reached 100%. worth a shot but i doubt it will help
or try wiping battery status in recovery
also, set up setCPU with profiles
Hmm.. I wonder how the battery drains even though it is off? o_o
Did you try turning it off, than remove the battery and put it back in? And see if it drains.
For me, my battery drains 0% overnight on airplane mode.

I just want to make sure when you say you turned your phone off you mean you shut it down right? I'm just trying to get a answer out of the way because I have seen so many post go a long way only to find out the original post misinterpreted a phrase. If it was in sleep mode a 20% battery drain isn't terrible. I've seen better and worse. If it's draining while it's shut off then I ask are you using the stock battery? It seems to be a big issue and I could easily see it leaking energy while off or giving misread.

there was an article on the xda homepage posted not that long ago. it was about how battery calabration doesnt effect battery life, but only the battery graph found under settings. basicaly it said that the batterystats.bin file only has to do with that battery graph, it tells the phone whats been eating the battery. here it the link if you want to read the article:
http://www.xda-developers.com/andro...-battery-stats-does-not-improve-battery-life/
anyways back to the point. nope i calibrated my battery a few days ago, so it didnt help

i dont know... and i used to leave it on overnight in airplane mode too with faux's kernel, it drained alot less leaving it on over night then turning it off. but the thing is, leaving you phone on for too long makes it sluggish, so i want to turn it off once in a while to help make it more snappy. I wanted to try that with trinity kernel, but ya thats not really working lool

I don't know what that has to do with anything and I would suggest trinity
Anyone?

I would suggest trying a new battery first. I purchased a couple of 3rd party batteries for $20. If it still drains while the phone is OFF, you have some sort of internal hardware problem.

sometimes it's the ROM, i've tried EaglesBlood, PheonixBlood and i get above then norm battery life. I'm on Xboard's OTA and my battery life is sweet
i'm having the same issue as well even when using 2 different batteries and an external charger (for the battery itself).
'normal' drain on the eaglesblood AOSP is about 20% an hour and when I turn off the phone, remove the battery, put it back in, and turn it back on after an hour, the battery drains till it's almost empty!
maxesxp, did the new batteries work? or was it some combination of rom + kernel that did the trick for you?
Weird I just thoughts about looking for this cause I had this happen for the first time. I was at 40% had no charger around so turned the phone off, turned it on the next morning and was at 2% effing weird!

My phone does this too. Some days it will drain only a percent or two and others it will drain like 20-30%. From what I can tell the kernel or something is not turning everything off on the phone. Try turning your phone off the next time you do and remove the battery and then when you go to turn it on put the battery back in and see if it drained then. If it did then it is a problem with the battery and if not it is a problem with the phone. If it is the phone there is not much you can do about that, sorry.
