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%
I've searched about a million times in 900 different threads, but I still can't find a fix to this issue.
I first noticed this when I flashed MIUI onto my phone. I would get cell standby and cell idle at about 40-50% of battery usage each. Display wouldn't even be shown on the usage! I then figured MIUI wasn't worth it to me, so I flashed CM7. I tried both morfic's and faux's many kernels, nothing seemed to fix the issue. If I would turn the airplane mode on, I'd get battery drain of only like 2%/hour.
So I figured there was something wrong with the CM7 port, so I tried g2xtreme and other GB ROMs, same thing. Finally, I just checked a froyo ROM, same thing again!
So at this point I'm clueless and thinking the phone is completely a POS, but anyways. I'm about to nandroid restore stock 2.2 firmware, and try updating through the LG Mobile Support Tool.
But I have my doubts that this will fix it. I'm curious though if maybe I'm getting this drain because I'm with WIND Mobile in Canada? And this is for the T-Mobile G2X (they're the same phone and both companies use the same radio frequencies). But maybe there's something written in these ROMs to tell the phone to look for the T-Mobile network? Which I obviously won't be able to find in Canada.
Can someone help me locate these settings, if they exist? Or can someone with a Wind phone maybe toss me the WIND stock firmware? Or let me know what ROM they're using without said issue?
Thanks guys!
Edit:: In low signal areas the phone drains like 15-20% per hour, in high signal areas the phone is still pulling like 8%-10% an hour and I'm not even using it! And the weird thing is it only shows 1% time without signal! Something is seriously wrong with this firmware.
Search for betterbatterystats on XDA, install it, enable battery monitoring in MIUI (if that's your daily rom), leave your phone alone for a few hours, then open BBS and look at the partial wakelocks under "since unplugged." There you'll see what's killing your battery.
Everyone experiences worse battery life when reception is bad, but you are still getting terrible drainage in good areas, which means there's something other than reception killing your battery.

I tried that before, and had a crapload of apps "frozen" with titanium backup.
I'm going to try this again, and I'll post a screenshot this time because I don't think I actually understood what betterbattery stats was trying to tell me last time.
If anyone can help me decode it later that would be great!
Just noticed that there's barely anything under partial wakelock that's noticeable.. RIJL Telephony is the highest with 1m 1s 15%.
But it's not increasing very much, only when I get a text message. However, I've dropped about 7% since my last message, and cell standby is increasing climbing up my battery usage from 33% to 42%. It went from 620uah to 657uah.
Edit:: I reset battery stats cause I was unsure if it was corrupted stats. I started at 17% 40 minutes later I'm at 12%. Phone was off 90% of the time. I made a 2.5 minute call and it used 41uah, while cell standby still dominated with 65uah.
However, I turned my phone on for 5 minutes, making total usage 45 minutes, but had the brightness set to max, and in that five minutes it only used 1uah.
Am I missing something here? At this point I don't know if my numbers are normal or not anymore... I'm going to try draining the battery, charging to full, wiping battery stats, and calibrating and see what happens but 65uah to 1uah is a huge difference, I would've thought display would use a bit more than that.
I noticed this morning that having the phone with airplane mode OFF, that my battery dropped 10% in 57 minutes, and after turning the airplane mode ON, the battery dropped 1% in the next hour and 30 minutes. I checked battery stats and nothing was waking up my phone. Anyone have any other suggestions?
I'm going to flash miui and leave it without any apps installed then try this experiment again.

I find these threads interesting because I am always looking for better battery life.
I am running EB 2.3.3
I uninstalled Set CPU and uninstalled Juice Defender. From my experience both hurt my battery life.
I never bothered to measure in airplane mode, because i use my phone to much.
My battery life improved dramatically during stand-by. 1% to 2% drop per hour with wifi on and a slightly bigger drop with wifi off.
I completely wiped the phone before installing EB and the used Titanium Backup to reinstall my apps without the data. I believe some of my previous battery life issues came from restoring data from certain apps.
I have the same phone/carrier. Do you leave 3G turned on? I feel it rapes my battery throughout the day. When I turned it off, it lasts pretty long.
Another problem I have though, is the drain when it is OFF. I went to bed with it at 90% juice and turned it off. I woke up 8 hours later, and it was at 65% when I turned it on. wtf. This only happens sometimes thou.. Other times it doesn't drop too much.

I experience the exact same issue. But for some reason my battery life is more or less the same with 3g off. So I feel like my phone is constantly searching for a different signal or something? I mean if airplane mode affects my battery life that drastically reducing consumption by like 9%/hour then there must be something up

Everyone who's been telling my phone is not sleeping is correct.
Only program is is that my phone's battery stats doesn't say which app is waking the phone? It lists Telephony as #1 with 1m 1s of awake time, and everything else is minuscule. There's gotta be something the phone isn't telling me :S Could it possibly be a hardware issue?
Or is there a better way I can narrow down this issue? I'm in the process of removing all apps.
Just curious, did you 'train' your battery?

Nope, but it's Li-Ion and my impression was these do not need to be trained.
I just emptied it to complete 0 yesterday, and charged it to complete 100% then calibrated it. Today though it was still horrible battery life until I completely wiped and flashed MIUI 1.9.23 then Trinity kernel brand new. I'm installing apps 1 by 1 to see which one caused me so much darn grief :S
All batteries are Li-ion nowadays, but I still feel after 'training' my battery for a week, they last substantially longer than new ones, fresh out the plastic.

Yes, battery drain is fixed. Also, I was on a completely different baseband for some reason, I was on the o2x baseband, fixed that JUST now, I think that was a part of the reason I was draining my battery like instantly. It was probably looking for a GSM signal!
Thank you for all your help

Yeah I set it to WCDMA Only. Battery life has been awesome lately.
I used to get great battery life with other roms on my galaxy but now since upgrading to the new ucla3 modem my battery dies extremely fast and the android system is always up around 48%! with the phone just sitting ill loose 30% over night when i used to lose 4% or 5% (about 9 hours). Any help would be great i just want to get back that amazing battery life

It definitely sounds like you have a background process running continously and you are not 'deep-sleeping'. Use CPU Spy and check to see if "time-in-state" clock cycles... you should be deep-sleeping 90% of the time during screen-off and know you have shutdown apps you normally use. My experience with UCLA3 modem is very favorable... faster data speeds and better reception coverage. I'm running it with the stock UCLA3 rom and UCLA kernel, and my Android system usage bounces around 1% to 5% CPU usage at any point in time. What rom/kernel are you running? Another suggestion is to use BetterBatteryStats app... great for checking which processes/apps generate wakups, partial wakelocks, and process times.
Ya i know what your talking about and i do have cpu spy and my phone is sleeping quite a bit but it seems that system_server just wakes it up and runs like crazy. im on nexus mod 4 and faux kernel undervolted. anything i could freeze to help with this?
BetterBatteryStats will tell you which processes ars generating wakeups and how many minutes /seconds they're actively using battery
OKay i think i found the problem with my battery drain just running a few trials to see if it really back to normal. will report back
Ya it was weird but i think that the battery drain was the ucla3 update on a rogers phone. not sure but when i went back to rogers radio and quikwiz rom my battery drain issues dissapeared :S oh well thank for your help though
CM10 battery life is pretty poor, anyone found a solution? I remember on defy someone improved by using stock battd folder in place of the original one, however desire s doesn't have this folder. Undervolted, full charge cycle, disabled auto brightness light to moderate use and only 8 hours. Display is main culprit according to system, maybe its getting too much voltage or something? I'm no dev its just a thought

Perhaps you should calibrate your battery with an app like battery calibration
"It's suggested, but not necessary, to let the phone fully discharge after calibration, then charged to 100% without break."
Make it twice or three time then you should see a difference.

Battery stats is a myth: http://www.xda-developers.com/andro...-battery-stats-does-not-improve-battery-life/
The difference seen is purely down to the full charge cycles done in this method, after about 5 days the battery stabilized anyway, thanks anyway

I have the same issue on Pacman (CM 10).
My - I hope temporary - solution is to disable 3G as much as I can. For everyday usage, 2G (Edge) is sufficient for me. At home I am on wifi anyway, so I perform the heavy tasks then.
I noticed a very big difference when using 2G only vs. mode "3G preferred". It seems that there is a 3G battery draining issue with CM.
3g is known to drain battery. Keep it at 2g for better battery life.

Hello, I'm currently running cm 9, however the battery life is just awful
When the phone is on sleep it loses like 1 percent every 5-10 minutes
I am using an extended battery as well, please tell me what to do I was on GB before and the battery was outstanding, I could go on one charge the whole day with heavy usage, now i dont think I can make it through the day with light usage on this
thank you
EDIT: This could be a sleep problem, because when the device is on, the battery is normal
If you flashed the Feb 27 cm9 you should flash proton kernel so you can watch videos. Battery life isn't as good as gb no matter what you do. Also give it some time to settle in. It takes more than a couple hours.
alright thank you... I just flashed the newest version of cm9 a few hours ago, I was flashing a bunch of roms and this one seemed the best... do you know how to force a device into deep sleep cause that seems to be the problem i believe
OK I was just on 20 percent, then i rebooted my phone, and now im on 2 percent... im seriously considering going back to gb
Sounds more like a battery thing? With CM9.? + Proton I'm getting at least a day* with light use. Maybe a bad app or combo of apps? What does BBS say is eating the charge?
* - I say at least a day because I can't not use it for that long.

just the screen and the android system... very interesting thing though is happening
I'm running a bunch of quadrants to get the battery down to 0, and the battery is all the way down to 1%, however it's been on 1% for like 6 quadrant tests... maybe its just a problem with the indicator, however another indicator also says it's at 1%... very interesting
If you are on CM9, I suggest you flash Hefe or Proton.
I use Hefe because according to the posts being made it puts your phone into deep sleep, which means longer battery life.

Definitely a battery problem. This happens to me on one of my batteries but not on another. Time to buy a new one. I haven't tested it fully but it does appear to be just a display issue. Sometimes the bad battery will make the phone display 1% but it will still act as if it had way more than 1% charge left. I haven't done any testing on that regard but that's what it appears to do.

I don't believe it to be a battery problem, because I've been on GB with absolutely no problems and exceptional battery... I just upgraded to ics not long ago, and the battery life instantly screwed up
Have you set the cpu governor to anything silly like performance?
Have you let it charge up fully at least once?
Search xda for "better battery stats" app, use it to see if you're getting deep sleep.
Flash hefe over release 8 and youll have a little better battery. Proton doesnt deep sleep
Sent from my SGH-T959V using Tapatalk 2
Proton DOES deep sleep. That was one of its major features.
Certain scheduler/governor combinations work better on different kernels, though. If the specific one you like most sleeps better on Hefe, great. If the one you like does best on Proton, great. Just be aware that most issues are either physical or user-inflicted...
In this case, your battery is almost certainly dying. The variance in power over a reboot is a definite tell that your battery is probably swollen. If you can spin it on a table, the cells are starting to die. This does not mean you can't keep using it, but it does mean that your battery life will be irregular. It also means that you'll have significantly "higher" battery levels if you reboot the phone with external power connected, but the battery will discharge very quickly if it hasn't actually reached whatever level it believes it should be at.
