I am running CM7 on a D2 and i am experiencing pretty short battery life. I went from Liberty 2.0 rom on froyo last week, and upgraded to GB and flashed CM7.
I have barely used it much today for example. Took it off the charger at 6:30am have done nothing more than sent a few texts and browsed a website for about 10 mins. It is 10:30 and i am already at 70%
I did a proper battery stat reset this past weekend also.
(i have also been getting a lot of random force closes)
since i cannot post pics here's relevant info...
Android version - 2.3.5
Kernel Version - 2.6.32.9-gca08d89
Mem Info - 214/475
Mod version - CyanogenMod-7.1.0-RC0-DROID2-KANG
Build Number - GRH78C
Battery info...
Display - 42%
Phone Idle - 18%
Cell Standby - 15%
everything else is under 8%, Android OS and System at 2%
CM7 GB Battery Issues
I am having this problem as well. Ever since I rooted and installed Rev's CM7 GB build a few days ago battery life has been much worse. I tried installing Jake's Mods V13 but if it is helping it is not helping alot. Yesterday, made 2 short phone calls, sent 3-4 texts, browsed web for maybe 10 minutes total, and was on tweetdeck for maybe 15 minutes. By end of the day was down to 30% battery. Pre-root and CMY probably would have been about 60% - 70%. Here are the battery stats when plugged it in at bed time last night:
15h 16m 23s on battery
Cell Standby 55%
Phone Idle 19%
Display 13%
Voice Calls 9%
Android OS 2%
TweetDeck 2%
Has anyone figured out a solution to this? Really liking CM7 but I am afraid to play a game or something on the phone because I'm afraid I will run out of juice!
CM7 does have a shorter battery life than stock and some other ROMs. It's still the best ROM and it will eventually be back to better battery life. I use SetCPU and JuiceDefender.
Should I go into the CPU settings on my phone to find ways to increase my battery life? If so, which setting should I alter?
I have been using the 1Ghz/undervolt option in Jakebitesmod along with Juice Defender and it seems to be helping. Battery will usually last me all day with moderate use.
You might want to try SBFing back and starting from scratch. I was on Liquid 3.0 and has atrocious battery life due to the 'Idle' process and was seeing 10-15% battery life drop each hour when there was absolutely no use.
I switched to CM7 and things were much happier. Maybe 10% loss after 4 hours idle. FB app did drain the battery once but I think I backed out of it while it was loading so it was trying to load GPS or something but outside of that no battery life problems what so ever.

I've also noticed that with the latest CM's battery life is an issue for me. Ive got KoR roms to last almost two full days but cm is dead within 20 hours.
My battery life has changed as well and I now have to keep my travel charger and car charger with me at all times or suffer with a dead phone.
i had been running rc3 with the 8-19 kernel, and my battery life was similar to stock, but the combination of latest CM and wildmonks are just killing me... i think im going to go back to rc3 with the 8-19 kernel.
Check the active processes. You can't drain the battery in 8 hours unless you have a process stuck, using 100% CPU constantly (possibly Exchange?).
good thought, but im not an exchange user... i cant seem to isolate the issue. im going to do a full wipe and try stock to see if maybe i have a bad battery.
People with battery life issues should try Enom's ROM with a wildmonks kernel. I'm 18 hours in of a full charge and I'm at 76%. That's normal use with full screen brightness, wifi and gps, quite a few background updating apps, etc.
Over 50% of power usage should be the display under even moderate usage.
With wifi, push, and poll active, the battery drop per hour with the screen off should be less than 1%.
If it's higher than that, you need to find the rogue process or get rid of an automatic task killer.

Display is most of my usage with over 50% every time. I have one app that auto updates in the background, Twitter, and thats every half hour. I do have 3g on but with wireless on most of the time. GPS, Autosync, and Auto-Brightness is on. I play one game twice a day, World War, once in the morning, once at night, but both times are usually on the charger.
Now that I think about it, Im a part of latitude but maps/latitude never consume battery according the about>battery.
Either way CM6 full charge starting at 4am, with light-moderate use, will be dead at like 5pm. I can go almost 2 days on a single charge of KoR rom. Enoms rom I have tried and lasts a full day +some...

I have the same issue and have had it since RC2. I can deal with it since I have the desktop dock at work, the car dock, and two wall chargers at home. The drain is pretty noticeable -- after about 30 minutes of the phone being off the charger and left alone with screen off, the battery charge is at 94% with "Display" using 65% of that. Wifi/BT/GPS off.
Like I said, it's not a big deal right now because I have chargers everywhere, but it's really annoying. I'm still searching for the fix, but if I can't find it, back to MCR for me.
I tried CM for 1 week and I must say the extra glitters is not worth the poor battery life., only lasted 1 day if used moderately. I just switched back to FRF91 Stock Rom today, lasts me 2days if used moderately. Longivity of the battery is another long term concern people should think about. I still miss my modded dialpad with big buttons, cool trackball colors and many more, CM is such a TEASE!
What kind of battery life are people getting with Pershoot's latest? It's undervolted, so it should do pretty well.

Tried Enom? I've seen zero difference in battery life, perhaps slightly better, since switching to it from stock Froyo on my N1.
In the battery use screen, what's draining the battery with the screen off? Let the phone drain like 10% with the screen off the entire time after unplugging.
several recent nighties and cm6.0.0 seem to have something broken.. Four hours of standby after full charge and the battery level already @ 83%.
cell standby 32%; idle 29%; display (wtf was turned off all the time) 28%.
Drains twice as fast compared to older CM roms..
The LEDs are also considered the Display by the battery meter.
Still, 17% in four hours is enormous. I guess I'll have to hold off on CM6 until they sort this out.
Dicks! 4% battery drain in one hour with almost no use, and that's after flashing pershoot's undervolted kernel. No way.
I'm going to try wildmonk's kernel now. :/
I get 4 hours tops.
I was getting almost 18 on j2.
What did i or need to do?
Did you installed another kernel?
I get great battery life...
I installed the stock jk6 that som posted.

Oh the post with the words and the zip file?
Lol we need more than that to help.... what post?
I get anywhere from 10-16 hours on Macnut 13 with JK6, depending on usage
4 hours with what?
Sent from my SGH-T959 using XDA App
I get great battery life with jk6. 5 hours idle and didn't drop even one percent, but it drains fast if I use wifi.
What if you delete MediaHub and DRMua?
I seem to get much better battery without those.
I also enable WIFI during sleep... it's in the advanced settings under wifi.
And of course I remove all of the other bloat apps.
JK6 with all the crap removed and I average 18-24 hours with moderate use. The lowest I've seen is 12 hours and I had the screen on for almost 7 of those.
Looking forward to when we get source code and can run an undervolted kernel.
I get really great battery with JK6. I suggest you to do battery conditioning.
JK6 has great idle battery life for me but as soon as i start to use the phone for low activities it drain faster. By "low activities" i mean as in making call, use map, navigation, changing settings.....
Here is my usage report:
3h since unplugged from over night charge
73% left
Display on for 45m 19s (lowest setting w/ auto brightness turn off)
Voice call 45m 21s
Cell standby 3h
Phone idle 2h 15m
To me this was worst than when i was running JI6. Also i lost 3G every now and then in the same area that i travel everyday.

Using maps and navigation are some of the most power-consuming tasks you can do with this phone. Navigation in particular killed my Vibrant dead in a few hours.
The kswap process eats a upon of battery when in use on the jk2 roms. I thought jk6 had this fixed, but it may just be better on the custom roms. I get great battery life on my jk6 rom.

Are you running stock jk6 or custom jk6 rom?
Getting excellent battery life, 1+ day with 30% left when I last charged it last night. I moderately use it too, some browsing/gaming, along with heavy texting and occassional GPS use.

I had similar battery life using various custom kernels. Installed Aux. 2.1 with stock. With heavy use I am running around 8 hours. Normal use around 12-16. Those other kernels will eat your battery alive. Try a stock kernel. Conditioning doesn't do crap.

noticed this also, doesn't really make a difference to me.
Most of these problems are user error. I woke up today with around 70% this mourning at 7am. Its 12 hrs later and im at 42%.
My Day:
combined 45min of calls
atleast 30 txt message
Ton of emails and they sync all day
Started my music player at 9 and didnt pause until 5pm. playing out of speaker
Browse the internet off and on all day
downloaded a 100mb mixtape torrent through 3g
screen brightness at about 60%
Probably a couple other things but app called Battery Left is telling me I have 10hrs left.
I really suggest running all stock. I need no lagfix/special kernal or anything with the newest leaked samsung firmware. Havent had a single issue since I switched to this rom.
I'm sorry, but I have a very hard time believing that, ALL THAT, only took 28% battery.
17%after a couple more torrents. Not wirth trying to prove but the stock rom made my extended battery worthless besides special occasions.

Thanks for the help. My battery died after four hours as expected. Plugged in and reconditioned and let it charge till it was full. Now It's been about five hours unplugged and I'm down to ninety six percent.
However as some of you have posted my battery drains VERY fast once I use it sparsely. It dropped almost 5 percent after a few mins of browsing the market. Weird. But whatever standby is amazing.
After using UOT kitchen to change the look of the status icons, mainly battery icon, has anyone recognized an increase rate of battery drainage?
Im rooted with fr008, LP, no ATK, gps off, Bluetooth off, WiFi off...blah blah blah. Standard battery saving stuff. Haven't changed usage habits, but noticed battery drops quicker.
In a matter of updating my status on Facebook mobile site, liking a friend's status, and writing this post...my battery went from 98% to currently 92%.
Phone has been on 1hr 46 mins and is at 92%
I wouldn't base battery drainage in the first 10 percent.

Just pay attention from 85 and on.
eh i flashed back to FR001. saw no real speed increase, no use for OC kernel and saw no real difference in HK kernel, on FR008.
battery just seems to last longer on FR001. able to hold 100% while no use, backlight off..for 2 hrs. when it would drain 4-6% after an hour on the same condition on FR008. for me personally, it matters.

After running it for a couple of days, I've noticed the same thing the others said. I notice a sharp drop from 100 - 85, but it seems to stabilize and drain much more slowly after that. I hit 35% at 10 p.m. last night after extremely heavy usage (four reboots, email, texting, phone calls, web browsing, etc.).
Glad to know it wasn't just my phone.
I manage to get 20-30% by the end of the day on fr001. I'd get that or lower by 8pm on fr008.
I hear constant griping about battery life since EB01. So I was curious what amount of time are people getting on their full charge? I am getting about 13hours. Definitely less than before but tolerable. Have done all the battery wiping techniques. Why is there such a different between users?
I get about 15 hours of good use out of it since updating to EB01. this is with moderate use.
After about 18 hours, I'm generally ~1/3rd the battery left. I'd say a large part of the variance is how we actually use it. I think it'd be good if at the end of the day, you wrote down the unplugged time, the % remaining, the % of the top several items in battery use, as WELL as the actually amount of time for each of them. Right now 'display' has used 41% of my battery, but only been on for 11m45s (the phone has been unplugged for 6h45m, with 72% remaining).
Without the full context, it's extremely hard to actually have any idea what's going on (terms like 'light'/'heavy' use are totally meaningless). One person that regularly gets 2 days (depending on my use I can easily), vs a person that can barely make it through a day... that doesn't mean that the latter person's phone is messed up, they might stream LOTS of music & videos, while the other leaves theirs in airplane mode half the time.
Edit: I'm on SC 2.1, with GPS, all location services, WiFi, and auto rotate off. I leave sync on always, and I'm nearly to 9 hours now... with still 72% remaining... and just dropped to 71%!
Horrible... with vanilla froyo v5 it was amazing, but every other has been almost intolerable. Sc2.4,blackhole,gingerbread... I've tried all of them, for several batt cycles. On second day of miui, ill report in a few days. I've always flashed at full battle, never have GPS or wifi on, turn sync off a lot, and always have my screen turned down. I'm at around 10 ta 13% drain an hour

I know I said I was getting 12-13 hours. Well I did the battery script download and am now at 63% after 12 hours. I would highly recommend giving it a try. It didn't seem to do anything the first day. More the second day couldn't be happier.

SC2.2 nonvoodoo with no power management apps. Overnight off charger for 8 hours battery loss is about 3%. My typical numbers starting from a full charge averaged below.
Screen 3.5 hours.
Calls 45min.
Gmail sync avg. 20 emails.
SMS avg. 30
TWS +/- 4%
BW weather updates hourly.
Those numbers usually get me to about 15-20% battery. So with that usage it can be done in one day or I have also stretched that usage over 2 days.
good day.
Anybody try any of the battery saver apps like super power or juice defender? I have tried juice defender but it wasn't toggling data so now I'm trying superpower & it toggles fine but keeps the phone in partial wake according to spare parts so I wonder if there's any real benefit... I'm now down to 11% after 10 hrs off the charge.

After trying the battery wipe script, and several battery cycles, I'm about 1/3 less battery life than I was on DL09. I'm hoping once we get source, we can get a LV optimized kernel to get it back to where it was.

I used Juice Defender back on DL05, but found that it made my battery run down faster AND it'd cause many of my apps to update inconsistently (using both the default setting, as well as others). Even after disabling, and then uninstalling it, my sync settings were screwed up until I flashed EB01.
I'm not going to trust any of those apps again... thinks work better if you just find apps that aren't power hogs (such as constantly polling the network!).
Back on DL09 SC 0.9, with Adrynalyne's undervolted Voodoo kernel, I could get two days with light usage without trying very hard. Now on EB01 SC 2.4, I struggle to make a full day. Not sure if the drain can be fixed with working kernel source code or not, but I imagine it will help a lot. Until then, I can't bring myself to go back to Eclair again, so for the moment I'm putting up with the poorer battery life and lack of Voodoo sound.

Well I decide to start this thread for us, to have a guide about wich ROM are we using and the battery average drain. Feel free to post you battery screenshots, and of course your information.
ROM
Average time
Percentage
Any tweaks.
Thanks!! Lets build some usefull information.
Hi,
I can only report bat usage on two ROM's since only used two till now.
JELLYTIME by Randomblame
Average time: about 13 hours
Wifi constantly on, mobile data also, average calls time between 3-4 hours, average of 1 hour of internet browsing, no gaming at all
Although it is a very good ROM, for me battery up time was a half that has with a stock ROM. It drains about 4-5 % per hour on standby
Any tweaks: No tweaks
CyanogenMod 10.1 Nightlies / M-Series by Mustaavalkosta
Average time: about 20 hours
Wifi constantly on, mobile data also, average calls time between 3-4 hours, average of 1 hour of internet browsing, no gaming at all
Battery time for this ROM is superb, I think it's a far better than a stock ROM. If I don't use phone much it can go 24+ hours on standby (Actuly I'm planing to do little experiment, to see how much will last on stand by only)
Any tweaks: No tweaks
Sorry I don't have screenshots
P.S. I think you should change thread title, since this is comparison between ROM's it's not guide for anything
If you guys are going to do this, it may be good to set more factors in. I.e.: age of battery, if on data, reception strenght and so forth.

Ok I 've got one of those 2450 mAh Gold battery's for my desire HD not sure if its the real thing or that high as it was only £7 on ebay but its better than my stock battery for sure.
I'm running AOKP 9/13 build with Sync on, Gmail push, some SMS ,Maps, internet, calls and running Android pro widgets for facebook and Greenify to kill Maps.
Today I have 57% battery after 9hrs 56m on battery
40 % screen
25% calls
15% standby
11% idle
6 % Maps
3% Android System
2% akmd (what's that?)
I think those stats are great and as good if not better than when I was running Mike's Android revolution HD 7.3.
Really pleased with AOKP very stable and no FC. Only thing is the proximity sensor works but sometimes must switch back on in a call, but I've heard this is a common problem with JB roms. I can live with that and I've heard of a recalibration app that might work.
BTW I use android pro widgets for facebook as I prefer it to facebook app and I'm sure it's better on battery life. Also less is more don't download to many apps, they bleed that battery with background maps and internet.
