I flashed Cleanrom 6R2, and my battery life has been draining pretty badly on idle. I've had this happen to me a lot after flashing ROMs. I've tried wiping battery stats in the past, and that didn't work, plus the version of CWM recovery I'm using right now doesn't even have that option any more. Any suggestions on how to stop this drain? Thanks in advance.

I'm very new to Clockworkmod, so I'm hoping someone can maybe will in the blanks for me. My D2G's battery life is getting worse by the day, and I've been reading about wiping battery stats using CDM. From what I can find on the forum, it appears D2G can't reboot into recovery, and I have to use Droid 2 Bootstrap? Before I do that, I wanted to first make sure that this is correct, and also see if anyone's had any battery performance increase by deleting battery stats?
I have a question about battery calibration.
After I deleted batterystats.bin, the meter seems to be working fine (prior to deletion, battery meter was not correct - for example, only 50% battery was remaining, but battery meter would be around 70%.
Anyway, do I have to calibrate battery each time I flash new/upgrade ROM?
I've been changing to different ROMs frequently nowadays to find best battery ROM. So I was wondering if I have to calibrate battery each time I flash new ROM.
Thank you!
Honestly I dont think it matters much. I've heard arguments both ways but what I do is I calibrate when I first get me phone (or a new battery) and thats it. I get great battery like even going between roms

You MUST delete the battery stats.bin everytime you flash a new rom

I don't agree with the word must. It would be a good thing after a few flashes but EVERY time is not needed.

Um.. no. theres a proper way to caliberate the battery.
If that was the case then I'd be wiping my battery stats everyday because of CM7 nightlies
But yeah, I'd probably say just do it if you feel that your battery life is awful. Maybe once every 3-5 months? I've had the NS since it first came out and I haven't wiped my battery stats. Battery life is still amazing, so I don't know.
I have updated to the official ICS (AT&T) and now I'm no longer getting much battery life. I had some issues with the update, so I wiped my phone and I have little to no apps.
I used to get 10+ hours of battery life, and now I don't even get 8 idle hours (so now it doesn't even last the work day). I checked Battery Usage after it was down to 20% and cell standby took up 90% of battery life.
I used to run JuiceDefender, but I reinstalled it on ICS.
Why have I lost so much battery life; how can I fix this?

I have noticed the same thing on the stock ICS. Also noticed very slow charge times using USB (possibly true with A/C charging but I am normally asleep when I charge with A/C).
Is this just caused by the bloat that they put in? I want to flash a custom ROM just for battery life at this point.

Im also seeing Cell Standby as a higher % than I used to.
install sky ics rom , this is the best battery . you can easy use more than 15hours . nexus mod 5.04 is also good . and much easier for noob to install . stock sucks .
Try Instigators Kernel. Does wonders for your SR battery....

Instigator's kernel is for AOSP (CM9/AOKP) so for ICS based official or roms you will need a different one such as mohan's kernel:

As for battery loss, there are some cases where if the flash wasnt done with 100% battery it could be reading the battery wrong and some people have had success with recalibrating their battery (look up battery calibration on play store). Now it was said that it really doesnt do anything for battery improvements and was just for stats use or whatever but for some people it helped their devices read the right battery stats.
Hi, noob here.
I'm in fact happy to upgrade from my horrible and outdated firmware (2.2) of my LG p500 to Cyanogenmod 10. there is only one (major) problem: my battery life fell to roughly 12 hours even when the screen is mostly off and the battery statistics tells me that it is mostly drained by the screen (50-70%, which does not make sense). I tried installing Easy Battery Saver only to see that it gives me the same stats and does nothing I can't do via the settings.
I don't want to disable wi-fi or mobile networks when the phone is sleeping, I need them. I don't want to deep sleep it. I just want to know what causes this sharp fall in battery life.
Is it because of the updated OS, kernel, whatever? Is it another service that I didn't have in the old firmware? Or is it just my battery being worn out when I was struggling with it trying to install a custom rom for the first time?
Thanks in advance for all the replies.
Think its the kernel, try reflashing it

Go to Settings > Battery, and it tells you what's consuming most of your battery.
If the battery usage doesn't seem to reflect your actual usage pattern, you can try re-flashing.

thanks for the replies. by re-flashing, do you mean I have to flash the rom all over again or just the kernel? and how can I do it?
Make sure that your phone is able to go into deep sleep. If not, your battery will be drained as well.

i have samsung 9001 and it was stock GB rom. after installing JB on it my battery time was reduced by around 10-20%. i think ICS and JB need little more battery than GB. or am i wrong?
I've tried stock 5.2 and different roms. Even in TWRP I find the battery is draining insanely quick. I charged it up to 100% and when I went into TWRP, wiped everything and installed Lineage OS and gapps, it dropped about 5%. At this point I'm not sure if the battery is just basically on its last legs from being on 5.3 for so long. Does anyone have any suggestions? Something else I can try flashing to see if it fixes the insane battery drain? I'm considering just selling the thing off and buying something else, but would want to try and salvage this thing if I can.

Flashing a ROM and starting it up (and installing apps) uses a lot of processor power, and therefore a lot of battery. A 5% drop flashing a ROM and starting it the first time would be completely expected. After flashing a new ROM I would recommend you use it for a day or so(drain battery to almost empty) and recharge; to let the ROM "settle in" and the battery meter to calibrate. Do this before passing any judgment on battery.
Severe battery drain has been a consistent issue on all stock Nougat builds. But I can't speak for Lineage, as I only run stock ROM (rooted). But it's an OS issue, not a battery issue. The worst case, if downgrade to Marshmallow, and it should fix the battery drain.
