I have a Samsung Vibrant and it's running CM7 7.1.0.1 with the following kernel
2.6.35.12-gdf10700
My problem is that the process "cell standby" has been killing my battery for the past few weeks or so. I'm looking for a new kernel that won't drain my battery so quickly.
Thanks in advance.
Im also noticing cell standby drains my battery pretty bad. Even with Ultimate defender
Have you tried Bali-CM, 99Problemz, or Streamline?
I installed Bali, but I'm not sure how to configure Voodoo Image.
Have you tried rebooting your phone after taking it off the charger? That has fixed my drain issues and lets the phone go into deep sleep properly.

For me the stock CM7 kernel works best. I am on the latest nightly.

What are u doing to get this kind of bat use? Is it just the latest build? What modem are you running?
Including 8 - 9hrs sleep (periodically waking to fiddle with World of War), I get 24hrs or slightly more on a single charge with MIUI (same backbone as CM7). I simply freeze or uninstall any apps that use battery that I don't need, such as Gallery, Music, File Explorer, etc. I'm also using an Epic 4G Touch 1800mah battery ($20 from Mobilecityonline) and am using the Glitch ML kernel for some ridiculous undervolting (in my signature).

Can anyone confirm that the Epic 4G Touch 1800mah battery works on the Vibrant?

hey guys, I have both the Flyer 3g, and the EVO View TAB. And i noticed the battery life on my Flyer sucks. it will not last half as much as the view. I think the View has a 4000mah battery, does anyone know if its the same for the Flyer 3G?
if not does anyone know if i can maybe buy a replacement battery for my view and solder it on my Flyer(assuming its soldered on)?
I haven't really had a problem with battery life... 8+ hours of work use (you know, youtube, note taking, checking email every 5 minutes...)
I don't know if anyone would bother creating an extended battery for this, since the battery is not removable... not saying it's impossible, but I haven't found anything...

I wish i had 8plus hours. I wonder if its the phone calling thats been draining my battery.
Well ... i use battery monitor all the time. What I found out is that with 3g disabled notetaking plus audio recording consumes an average of 600 mah. With 3g enabled it jumps up to 850. With 3g enabled i get 4h 30m display enabled. Without 3g but still using wifi i get 6 hours of display enabled
Think about getting a battery pack like the treckstor dual port. It can charge the flyer up to 80% battery life.

Thanks, I'll give it a try.
Let try custom ROM.
The official rom make me unhappy with poor battery life.
I try many custom rom.
Custom Honeycomb still no good in battery life.
Now,i use i00 GB 2.3.4,it 's good battery life for me

at the late morning,i read the pdf paper for awhile
afternoon,i play the online game with WIFI
alway on 3G internet and bluetooth headset.
it's good for me.
as the title says. I am looking for ways to get my battery to perform like it did before.
I was using villain rom with SPEEDMOD kernel.and I had very good battery life. one night I noticed my battery getting really really hot while charging. then the battery life went down hill. I tried wiping battery stats, removed battery for 5min after full charge, changed to cm based rom(it was even worse). i upgraded my modem to KI4. Now I am in villain rom with SPEEDMOD, (17) kernel and the battery life is still ****.
any suggestions####. yes I could blame Android os bug. its a 2.3.5 rom and I turned off all the sync as well I have absolutely no idea how to solve this issue.

it is with minimal use. theme is not the culprit as I have tested without theme and got a similar results.

update
I did not want to change the ROM but I gave 'HyperDroid-Androidmeda' a try. to my surprise the battery drain was gone. then i installed ics theme 'the battery was still good'. then I set up google account and restored K9 mail via titanium backup. THEN AGAIN the BATTERY started to deain heavily.i uninstalled K9,but the battery drain had not gone, uninstalled titanium backup no LUCK. still investigating......but i know i am close
The batteries used in the SGS2 do not need (and therefor not offer) calibration.
Your problem is something else and there is about a million threads about how find'n'fix the issue.
Out of the blue, I'd blame some app you're running.

I am aware of all the other threads. I've faced battery life problems before as well but it was usually resolved by flashing a different kernel or rom. you may be right about the rouge application.

can anybody help me make sense of what is killing my battery. btw I did ude the audio recording software for an hour and also the circuits app but they are not the culprit. main problem is that the phone does not go to sleep.... and battery drains rapidly.
i for first 50% of charge i was on speed mod kernel ... there was battery drain. and then i flased the rom again, the battery life got worse.
Sent from my GT-I9100 using XDA App
UPDATE....wifi was preventing my phone from going to sleep(still dont know what the real cause is)..... AFTER several ROMS and a DEAD SD card... my problem seem to be gone...for now at least. i basically flashed official firmware and flashed speedmod for root and clockwork mod. then flashed checkROM with speedmod again. fingers crossed the problem is gone.
My rate of battery loss is insane. I can sometimes lose more than 14% an hour while using it. That's with cm7 and the extended/fat battery! Is this normal for heavy use or is there something inherently wrong with my phone.

what apps and hardware (bluetooth, etc) are you using? what is your birightness set at? are you using 4G?
No bluetooth. Mostly baconreader for reddit. 4g strangely makes no difference. Normally it is off, but I have found that the angle of descent is not impacted by switching. Brightness always sub 40%

Something else has to be running. I get better than that with stock battery and heavy use.

Is that an antivirus in the first screen?
My brightness (in a profile) is set to 15% and I run that 24/7 unless I'm outside making a phone call or something to see the screen . . .
Could be the antivirus. Have you tried battery calibration by nema? (In market) I'm running infected and using the same battery (OEM right?) And I get about 5% drain an hour with 4g on and screen on about half the time. Sometimes more or less depending on usage.

Doesn't that just clear the batterystats file on the Sd card? That doesn't affect use unfortunately.
Sent from my ADR6400L using Tapatalk
I could be wrong, but isnt juicedefender an app constantly running? Have you tested your battery without that app?
Sent from my ADR6400L using XDA
First off thanks, I now feel better about my battery life. in my opinion battery life depends on a lot of things. Juice defender didn't seem to play well with my phone. I only turn on wifi when I need it. Also I would charge to phone to 100% and reboot into recovery and clear the battery stats. Not sure if any of that would help, but it can't hurt to try.
I've noticed a bit more accurate readings when resetting battery stats, which is why I suggested it.
Otherwise, you could try a complete backup of all your apps and trying a different rom?
My battery lasts about 14 hrs with regular to heavy use. 11 hrs on the fat battery seems like its way too low. Have you rooted and unclocked?
I would unistall juice defender. You can set up the phone just as well without it and have one less app running (which uses battery)
I have an avg of about 12 hrs fully cycle since i bought my phone over a year ago. I have to make sure that all the setting (i.e. GPS off, wifi off, screen turned all the way down) are always correct to push anything past the 12 hr mark.
Your best bet is do like the rest of us and make sure you have a charger always ready if you are ALWAYS using it.
I'm loosing my mind! Almost every ROM/Kernel i've tried so far is seeing some serious battery drain due to the Android OS service @ 50%+.
Is this normal?!?! I don't use my phone much but I keep having to charge it twice daily. I've also calibrated the battery using the unlimited amount of guides and apps, but no go.
So far i'm trying all the AOKP ROMs and they all do the same thing, even with different kernels, different CPU scaling governor like ondemand, smartassv2 and hydra.
I think i'm going crazy,

Your phone isnt going into deep sleep. You see it on the blue line under the discharging graph.
Are you using live wallpaper?
Sent from my GT-I9100 using Tapatalk 2
I bought batterystats and just not sure how to read it. I've created a dump file from it and attached here.
I'm not using any live wallpapers, and have downloaded very few programs such as doubletwist, chrome beta, battery calibration, dropbox, fasterfix, go launcher, team viewer and titanium backup. But even without those apps I was still seeing battery drain.
Delete all contents on usb storage except for music and videos.Wipe cache and dalvik.Restart phone.Let it settle for a couple of minutes.Should be ok.
I did that and now I wait. I'll report back tomorrow hopefully with good news.
I noticed that with CPU Spy shows that one of the Unused CPU states is Deep Sleep before so I'll check that out after this.

You have got same crazy apps running in the background. If your not hitting deep sleep you have a serious problem. Another thing to clear is media storage .

After running the kernel cleaner script, wiping data/cache/dalvik etc, I installed Wanam's newest ROM JHLP9, and now no more Android OS keeping the phone up from deep sleep.
It seems to me that all of the AOKP ROMs have some serious battery drain issues, or just bad luck.
Hi, this is the battery life on my RAZR, is this normal or I need to replace the battery already? (had the phone for a year now)

If you have the root try use a battery caliber from play store...
if not full discharge the battery 1% ok too
turn off the phone and full charge for 3 hours
this will increase the battery life

This was after battery calibration, I have done the fully drain and charge a few times before trying to fix this issue but still happening. Don't know if the power spike drops are because a wrongly calibrated battery or a bad battery, this happens on any rom btw, currently running Slimbean 2.2

That seems pretty bad...I would suggest that you may need a new battery. However, my phone is older than yours and is still doing well so idk.
This is my battery life after fresh install of slimkat 2.3 with jbx kernel 2.1.5 have you tried to use a charging app such as DU battery saver? link here: https://play.google.com/store/apps/details?id=com.dianxinos.dxbs

Problem doesn't seem to be the battery life, is the spike drops that bother me, if those didn't existed battery would last 1/3 more.
Already tried DU before, spikes still happen and battery saving are minimal since this apps help when the phone is no in use.
