I am using a friend's old Bionic as a backup after my GNex broke and I am seeing Android OS reported as being very high in the stock Android usage Battery Meter - I don't see any major wakelocks in BBS either.
Anything that might cause this or anything I can freeze, disable, etc to fix this? Any other information I can provide that would be helpful?
Thanks in advance.

normal for bionic since ICS and JB...go with a rom or de-odexed...plus even it being on the high end its not really soaking up that much battery juice. its an overall of all the apps you have that need constant updating.

Any recommendations on a ROM? Is there a stock Bionic ROM that is de-odexed?
Also do you see an increase in battery life by switching to a ROM?
Thanks in advance.
As far as battery increase.. you might get a little increase. Eclipse rom has always been good. And liquid smooth. Its all trial and error. Use safestrap so you have stock rom saved. Use the the other slots to try different roms. Im using stock rom that's been de-odexed and debloated. Also have OEM extended battery 2760 mah. I consider myself a medium user. Can get me through the day no problem. BTW if you use juice defender to name one.. I don't care what anyone says .. any battery saving app out there is a joke.

Hello all,
I have seen reports that because the source code for the captivate has not been fully released, some of the processes cannot be put to sleep when they are not being used, and therefore causes bad battery life. I am just about to flash CM 7.1 and am curious to know how the battery life is on the captivate.
All info is greatly appreciated!
LWt mw know what you find out! Just flashed it and my battery goes quicker than my bank account. Please let me know what I can do to help this I like the rom

Jaye,
This happens frequently when flashing a new ROM, you should try wiping the battery stats or giving the ROM a few days to calibrate with the battery.
Been a week for me and battery life is still horrible. I lose about 25% an hour

You should try a custom kernel like glitch or Neo to see if that will help. I get awesome battery life in miui which is bases of cm7. I find that neo gives me the best battery life.

What do you think about the Boog Kernel?

Also, some people must be getting solid battery life, or CM7 wouldn't be as popular as it is. Or is this a known thing with CM7?

Yeah that's pretty awful. Try doing a battery calibration to see if that helps. It should never go that quick (unless you're playing some serious games). I've never really had great battery life with cm7/miui I've had the best battery life with all the recent samsung gingerbread leaks. I think those are better than cm7. But that's my opinion.
I am in CM7.1 since Sunday. I had very awful battery in start. So I did battery calibration, manually. So I got very decent battery on wifi. But at work I use att data so again my battery life was horrible. But I am seeing improvement since I am using this app called green power to manage my data. Try that.

If you get good battery on WiFi but not with mobile data, try a different modem. Not only are some modems inherently better on battery, but if you find one that gives you a better signal you should see improvements in battery life as well.
Flashing the Glitch kernel seems to have improved my battery life.

Hi, Can you point me to a post that (a) has the Neo Kernel and (b) explains how to flash it on MIUI? I've had MIUI for a couple of months now and battery is to as good as expected. Would love to try to use another Kernel but I sincerely don't know how to do it.

Solid Battery Life w/ Stock Kernel
Hey Everyone,
Juts came to report that I have been getting great battery life using the stock kernel. I would say it is a little better than Serendipty VII Build 2 which I came from. Only issue, and this is something I know is inherently wrong with Cyanogenmod on the Captivate, when you fully charge the device, it only shows it is charged to 98%.
Other than that, all good!

Have you seen an improvement in this regards, I am having the same issues, the WiFi is draining my battery slower then my data is.
I have also done the battery calibration and it doesn't seem AS bad... still doesn't appear to be great though.
I am just coming back to this ROM after experiencing battery issues even though Glitch helped a little. I decided to try and tweak some more this go round.
I am experiencing much better results this time. Here are settings and other tweaks or modifications I have in place.
-sync is turned off
-using Launcher Pro with very few widgets (just 3GWatchdog and Power Control)
-auto brightness turn off manually adjust according to need
-gps, wifi, BT, and data turned off when not in use
-wifi notification and location detect off
-installed jk4 modem (may get better results with different modem depending on your area)
-installed Glitch v12 high leakage
-the biggest factor this time I think is UVing on the Freqs that are used while phone sleeps >>>>>100/200mhz (set for the lowest UV setting possible on these that do not result in a sleep death or reboot when phone is put to sleep)
Hi all
I've unlocked the bootloader on mine through the htcdev site and am currently running Niks latest rom.
However after flashing Nik's latest rom, I'm finding that my battery life has been horrible (i very much doubt its the rom, lots of people have commented on great battery life with his). Can just scrape through a full day's use of texting, some web browsing and music playing. After some browsing on the phone, it goes down from 100% to 90% in about 10mins I've tried increasing my battery life by following the method found in this thread http://forum.xda-developers.com/showthread.php?t=701567 but it still hasn't worked for me.
After reading the forums, I've heard that unity's kernel supposedly brings better battery life and am considering flashing it. However I'm not sure if i can flash it given that I haven't rooted my phone or done an s-off?? Can someone please give me an answer on that?
Also, is there anything else I can do to increase my battery life?? It's so annoying having to impose restrictions on myself to increase battery life when my friend's S2 drops to 98% after some browsing and 3 hours of standby...
Thanks so much guys
sometimes, a custom roms make your baterai drain fast.
why? so many tweaks and overclock at cpu.
so, you have other options to change your custom rom.
example, ARHD 2.1.3 make your baterai not drain fast.
If you don't have full s-off, then you are restricted to whatever kernel comes with your ROM. I'd recommend you look into SetCPU if you haven't already, which will improve battery life by regulating how your processor is used. Juice defender is an app worth looking into as well. Have you tried flashing an earlier version of the ROM? Sometimes you can get a build where the kernel just doesn't work well. You might find your battery life improve with an older version, with a different version of the kernel. You have nothing to lose by trying I guess.

Hey guys, just thought I'd poll and ask some questions?
So if looking for the best possible battery life (over peformance) which is recommended,
true official stock samsung ROM? or stock ROM e.g. Adrenaline ROM etc
I've tried Stocklite, Adrenaline and am currently using Thunderbolt. However my battery life never goes over a day, even with Juice Defender Ultimate and SetCPU profiles.
Any one else have any experiences with good roms? Battery calbiration tips? charging tips anything?
Thanks

1.The battery life depends more upon your baseband rather than the roms.
Ofcourse the roms do make a difference!
Eg. Earlier i was using Stocklite v7.1 on DDKQ8, and it used to last a day, now on XWKTM it lasts more than that.
2.The battery calliberation is said to be a myth as an official google android developer stated that it does not affect the battery in anyway. (Tried it personally too, no change in battery life!)
3.Underclock when you are not using heavy apps on your phone.
4.The way you use your phone makes a great difference, switch off the bluetooth,gps,data,wifi when not needed! Reduce the brightness, it saves the battery!
Hope all this would help you!

Charge completely and get a log using BetterBatteryStats. This will tell you, and us, what apps are eating your battery. If you can, take a screenshot of the Battery section in the settings too, with a screenshot of the details of the screen item in there too.
Have you tried changing ROMs? Or maybe it's time for you to get a new battery

Just bought one "original samsung", it;s worser than my old one, heating and low capacity.
FYI - picked this up about 2 months ago, and it's been working just as well as my original battery. The charger is really cheaply made, though!

I do so much work on my phone so need one that is smooth and quick with great battery. I have Pure Nexus now and it's fine but sometimes it seems to lag. Maybe they all do when jumping through lots of apps. Maybe I need to reboot daily to keep it smooth.

I don't think it should lag but you may give custom kernels a try.Lag sometimes happen due to throttling after heat.Custom kernel manage these issues at ease.

OK thank you. I have 3.10.40-PureKernel-Shamu-2.04 so it's a custom kernel meant to work fine with PureNexus I think. I'm sure it's just because I'm using nav, and other high usage apps.

IMO android uses a very smart way of managing stuff when multi-tasting to reduce lag.So it is still highly doubtable.
Why don't you try some other kernels and overclock possibly?

Right now the phone doesn't last till much past 6p so I don't want to clock even more in case it uses more battery. It used to last longer so maybe when updating to 7.1.1 with the newer Pure Nexus that took some more. Or maybe it's just a 2014 phone with high mileage =). I used to go to sleep and overnight it hardly used energy now I notice when it's just idle it can use 20% overnight, maybe more. It could be an app I downloaded is running.

Awesome thank you for that. I'll probably give it a try. I think it was in the top 5 custom roms on an article I read.
i finally switched to 7 on pure nexus...it's great...smooth...fast...had it running almost 300 hours without a reboot and it was still going strong...i haven't tried nitrogen...so can't say...but am happy with pn...i came from chroma rom...
Roms, Kernel, and Age are all irrelevant!
A phone will last as long as the battery allows, and that's based on your usage of the phone. Period!
You use a lot of apps, it's going to die quicker.
You stream a lot of music/YouTube, it's going to die quicker.
There is NO magic combination of Rom+Kernel that is going to magically make your battery last longer.
Your battery has X amount of usable stored electrical charge, and your phone will use it accordingly based on what you do on it.

I don't think he understands or maybe is oversimplifying what he means. The Rom and the Kernal which affect the amount of systems running will affect battery life. The age as in the amount of times you've discharged and charged your phone over months and years will affect the battery life. There are tons of variables that affect it. One can say the kernal and the rom if they are running more systems or less then that's what he means by saying if you use more apps then it uses more battery but that isn't magic that's just use. So if you put a certain kernal and rom then that is affecting what you do on it which affects battery life. The X amount of storage a battery has degrades over time. The first answer when googled is below. I probably have almost 1000 charge cycles now. Nothing I can do about that.
"Charging a battery forces ions from the cathode to the anode; using the battery reverses the flow. Over time, this process wears out the cathode, which results in reduced capacity. A high-end lithium-polymer battery can lose about 20 percent of its capacity after 1000 charge cycles."

You wanna know how i went from having 10% battery life at the end of a work day to having over 50% battery life???
I stopped installing **** on my phone that i didn't absolutely need.
And low and behold, my battery life "magically" increased itself.
