Hey please don't tear my head off, Ive been looking through all the threads that I can, but haven't really found an answer.
So I got my g2 and left it stock for a couple of days and the battery did pretty good, meaning I didn't have to charge it during the day. I then rooted and flashed cm 6.1.1 stable and the battery was terrible it would drop about 1% every 5 min or worse if I was playing a game or using maps etc.
I tried switching to pershoot's cm_2632.28 012211 and it was just as bad. I then tried reverting to a back up of stock and it is still bad, I also tried RC4 and one of the nightlies, same problem. I tried wiping the battery stats with the instructions on cm's wiki, still terrible.
It is really frustrating to me and I have been looking around and it seems a lot of people are having trouble with battery life. I don't really want to buy another battery, and have tried removing anything on my phone that could use battery (widgets, apps, etc.) I also think it's odd that Cell Standby takes up the most battery.
So really what I want to know is does anyone have an idea of something for me to try? A mistake I might have made? Tip? Or am I just crazy in expecting my battery to last the day on stock?
Any help would be appreciated thanks
A lot of people who ran the cm rom seemed to have this problem I don't and I assume it only happened after cm and still occuring I think somethings wrong with cm's kernal idk but it seems like it shorts out the battery because I ran a wrong kernal on my stockrom and had terrible battery life.

The battery truly might be a dud... The fact that your Cell Standby consumes most of the power is probably normal because you said you stripped your phone of widgets, apps, etc.
My gf has a Wildfire and her first battery couldn't last more than a couple hours, and she's a fairly light user. She switched out the battery and now it's fine, goes for a couple days now..
I am running cm 6.1.1 oc to 1.2 I do not have this issue. Try a new battery maybe?
Which kernel are you using? And with what settings?
Kernel is toxygene #1, screen brightness auto, gps off, bluetooth off, Wifi only when I need it, "wcdma only" so I don't get any edge drop-offs, overclocked to 1.2ghz-368mhz screen on, 245mhz screen off. My battery will last 9-12 hours of normal use, that's a few calls, some txting, facebook, mp3s in the car on the drive home from work, and an hour or two of XDA. I unplug at for work at 10am, I let it die and charge from 0 every day..
Google sync every hour, weather widget sync 4 hours, facebook widget every hour. Those are all my widgets.
You should really upgrade to CM7 now. Pretty stable, and my battery life is SO MUCH BETTER. If I use my phone heavily I will lose about 30~40% during the ENTIRE DAY lol. So my battery with moderate usage will easily last 12 hours. Before I had the exact same battery life as yours.
Also, I'm using the UV kernel from pershoot.

I'm on Virtuous v0.9.0 and I routinely get 12-15 hours a day out of my phone. That's with brightness set full, WiFi running (and usually connected), Tweetdeck, gmail, gtalk, etc all running with constant updates, etc.
If I pull it off the charger at 7a, by 7p I'm typically still around 20%, depending on how much extra use I've done (sms, voice calls, etc)
Yes, the newer version of virtuous is great on battery life and doesn't even have to be oc. I just flashed back to cm today to get everything up to date (I'm ocd like that and have to have all my ROMs current) and I too am having the cell standby issue with 70% battery after 2 hrs and light use. Just flashed the newest pershoots and letting it fully charge before I clear batt stats... will report back.
Have setcpu set to lowest with screen off and oc 1.2-346mhz

synchronization
I am using Visionary 0.9.0 and I had lousy battery life too, and have now either turned off background synchronization or at least made it very infrequent for all my apps that use it (facebook, peep/twitter, HTC Sense, HTC Hub, News, Weather, etc. etc.)
This has made a very big difference!
The biggest difference of all came from turning off synch within the HTC Sense and HTC Hub apps. These were having trouble connecting to their servers, and were constantly tying up my 3G signal causing battery drain. This change alone has almost doubled my battery life.
I recommend you check what is using wifi/3G and how much before we assign blame to kernel or ROM.
Also, I can recommend GreenPower app which turns off connectivity automatically when it's not needed, greatly extending battery life. However after a long period of using this successfuly, I have turned it off as I started having trouble "waking" my 3G connection during the day. Hopefully future updates will help with that app.
I had the same problem with my first G2 and after complaining/convincing T-Mobile it was defective, they sent me a replacement and that problem never came up again.
Alright I feel stupid but I was charging my phone with my bluetooth charger (didn't even think about it) but now I'm using the stock charger and my battery is lasting way longer. Night and day difference. I don't exactly understand why this would make such a difference in technical terms but eitherway major facepalm.
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...
when i first installed the latest release i had amazing battery life. Now im at 70% an hour an a half after i unplug it and it prpbably wobt last me another 5 hours. I dont think i have any apps draining the battery. Ive wiped battery stats. What's going on?

If you used 30% in just over an hour, either you used it too much, or there is some app/process draining the battery. Download Spare Parts, go to Partial Wake Usage in the Battery History. See if anything stands out. If not, re-wipe everything and re-flash the rom. I'm running the same rom, and can go at least 3 days without charging.
battery usage history force closes spare parts...
Same here, it force closes when I look tap history. However I stopped using the changing photos lockscreen and my battery life seems to be improving.
World peace with no regard for human life.
standard wallpaper, and wallpaper lockscreen. I re-flashed the rom.
I had the same problem with an extended battery, only it would charge to 80%, then it power itself down and the battery would die. I took it to Sprint, they were awesome, the tech said that the modified scripting from the 3.0 Sense Roms is causing this problem on some phones, especially with extended batteries, rather flash my phone to stock, he gave me a differnt battery, wiped dalvik, said he did acouple things to it, and advised me to run a different ROM and see if that helps, preferrably a hybrid that the battery scripts have not been modified. I think alot of it was somewhat bs, but my phone holds a charge now, I am currently looking for a different rom...
It started out draining real fast, then it wouldnt charge after a few days
Hello all together
I'm browsing xda for a little more than a year now. You guys helped me a lot!
First I want to apology my english, I hope you understand what I want to say
Not a long time ago the battery of my WFS lasted up to 3 days (incredible if I think of it now).
That was with a self rooted stock rom and some changes (bravia, turboboost script, oc-kernel, etc.).
Out of nowhere I had problems with my calendar.sync.provider. Processes htc.bg and htc.bgp used the most of my battery (found out with Battery Mix).
I could watch the percent falling... Battery was getting very hot.
After i killed calendar.provider and calendar itself those bg-processes disappeared and all went back to normal.
Installed m1nd's rom, tried a lot of different settings, used calengoo instead of normal calendar (uninstalled the other)...
But battery life was never the same since then.
We also had a really rough winter and I was outside a lot. my battery began to drain faster. First I began to install apps like "auto wifi toggle" to stop that battery drain, after all I just bought a new battery this spring - 1500mAh.
But other than i expected - battery life did not increase. So I decided to install CM7.2 (wanted to do it anyway - great work btw!).
And guess what, nothing changed...
You will find some screenshots at the end... (did barely use the phone this 4 hours)
So what can I do? I'm desperate. The battery does not hold the whole day...
Please give me some tipps (if you have others than the general battery saving thread) or at least cheer me up
tl;dr: Phone works for 10h (mail,text, no phones, no games) - Changing battery & ROM does not fix battery drain...
Thank you in advance!
it happens to me too unfortunately, i charge it everyday or every 2 days
when i play a small mini game for a few minutes, battery drains like over 10% in a few minutes.
Have you tried calibrating the battery?

Hey scilax can you please tell me how to. Calibrate the battery.
Me too get a smaller backup when 3g is used for some 3 to 4 hours.
Please tell about that calibrating

Thing is, I charge my phone everyday. And I've been using CM7 or CM9, battery life never lasts more than a day. If it's only lasting 4-10 hours. Check your sync settings. Keep it only on 2G networks if using data. Get a battery saving application, in my opinion, it sounds like your using a lot of mobile data/wifi.
Hi,
This question is for anyone using the latest CleanRom on their Note II. Just wondering if your average battery drain is around 4-5%/h. I use BetteryBatteryStats. I also check the Battery section under Settings. The most battery life I have been able to get is 12 - 15 h with 1-2h screen time. At this point, the battery is at less than 10%. Is this normal ? I thought I remembered getting better life from older versions of CleanRom. I know these numbers are never achievable on any AOSP rom that I have tried. Just wanted to see what everyone's experience is with battery life. Just post any thoughts!
Thanks for your feedback! I appreciate your time!

Just like anyone else, it all depends on what kernel you're on and what apps you have wakelocking. I've been using Clean 5.0 as my daily for months and the battery life lasts me throughout the day until I need to sleep at which point I plug in... but sometimes, I'm running into fast battery drain due to some apps going nuts on me or when Bluetooth is trying to link from a long distance (where the phone would heat up and drain like mad... btw this only happened to me twice in many months). After a reboot, it usually clears up and after a recharge, I'm back to 14 hours with 20% left at night. I'm not one to be anal about my battery drain if it lasts me until I sleep (because I have NEVER had a smartphone that would last me that long without plugging in... in fact, barely half the day would be when my device would need to be fed).
I'm using Perseus' latest with a few screen tweaks, no CPU or power tweaks, using Facebook constantly, Pulse, SMS/MMS, camera throughout the day, Next 3D launcher with all the fun animations running, YouTube, Pandora when driving (so my Bluetooth is on constantly)... let's just say I'm a heavy user. When my kids get a hold of my device, they run a bunch of games and drain around 10% by the time I get it back.
I am happy with the battery life on my Clean Rom 5.0/Perseus Note II. I won't fuss about it as long as it lasts longer than half the day because that is what I was used before upgrading.
