I have tried both Eugene's and TeamWhiskey's ROM's.. Ginger Clone, OBSIDAN and ONYX. And all 3 have sucked down my battery in about 12 hours flat with me doing nothing to the phone but loading SystemPanel to monitor the CPU and battery. With all the ROM's the CPU usage has been between 3-10% while in idle. zero phone usage. I have refreshed the battery with every new ROM load.
I was previously using TeamWhiskey's 2.1 Bionix Fusion and was seeing between 1-3% CPU usage at idle and had the battery lasting well over 24 hours with minimal use(checking email, couple short phone calls)
Am I the only one having this issue?? Does anyone else use SystemPanel to monitor their CPU usage and can say what their CPU is using during idle??
Thank you for your time and any help/info you may have.
I don't use the modded versions of Froyo but Stock has awesome battery life from my experience. JL5 is looking great as well.
You or anyone else happen to know where I can find a copy of the stock 2.2 ROM/kernel?? I have an unlocked phone in Japan and it's not supported here, so I wont ever get any updates.
Yes the custom roms have terrible battery life. They always have. However, the stock roms have terrific battery life. After a long day of heavy usage I am at 50%

There isn't really a stock 2.2 Rom for Vibrant because it hasn't been released yet. We have leaked builds (JK2, JK6, JL1, JL4, JL5) that are candidates for release. When they actually release Froyo for Vibrant, that will be your stock froyo rom.
The key to great battery life is using the Stock kernel. Flash that kernel on any ROM and enjoy not having to watch your battery indicator all day.
yea, just read a thread about people complaining about that.
guess I'll just flash back to 2.1..
Thanks for all the help.
I flashed nero v2 w/ voodoo and i reset the battery stats, and now im having trouble draining the battery down to nothing.
Fear the beard...

I'll give it a try.. nothing to lose.
To drain the battery, I usually turn on Bluetooth, Wifi, GPS, all the good stuff. Then I downloaded this one Flashlight app from the Market which essentially displays one color full screen, default white. Crank up the brightness and run that app on white and it'll really put the hurt on your battery.
Edit: Today I learned that this may be potentially harmful information. Will someone give a good scientific explanation why though? I'm curious to learn more about batteries. However, this is how I've been draining my battery and it is a damn good method if that's what you want done.
Mine says 2.6.32.9 no matter what kernel i flash. Try flashing it just to be sure. I've tried all the ROMs and they all drain hard until I add the stock kernel to them. Though now a days a lot of ROMs include the stock kernel (Macnut and Axura for sure do). The problem with all the custom kernels is they dont seem to let the phone sleep so when your screen turns off the phone keeps draining as if you were using it. Stock fixes this so when your screen turns off barely any power is used. I
But like I said.. reflash it just to be sure.

Android is based on Linux and uses the Linux kernel as a base. The Linux kernel your phone's kernel is based off of is version 2.6.32.9
ok.. think I loaded the stock kernel up.. lol I'll let it run for about an hour and see what kind of CPU numbers I get in idle.
Thanks again for everyones help/input.
FYI.. just put it in flight mode for a bit and CPU usage dropped down to almost 0%.. I'm not understanding why it cant do that when the phone is idle.. ahh well.
Idle for an hour should lose no more than 1% battery depending on how much stuff you have polling and updating.

I want to start off by saying that I am a NOOB at this rooting and custom ROM stuff. I was getting ready to toss this Vibrant in the trash when I said to read up on rooting, follow the steps provided, and install a custom rom. XDA you have saved my phone. I want to thank all of you who provide all of the support here. I installed Bionix 1.3 and I am in shock at this phone now. GPS actually works in real time. The phone is superfast as well. The only issue I have is that I can't surf the web or check FB without my battery draining like 3-5% in a ten minute span. Its crazy. Battery does well in standby mode. Extremely well as a matter of fact. not sure why it drains so quickly when I actually use it. I have wiped the battery stats and done the battery cycle. Overall still love the new look. Keep em coming.
Glad you found a new appreciation for your phone through xda. As we all did.
Your issue is with the kernal used in 1.3. The OverStock kernel. I've had the same issue. Great life in standby 1% an hour vs on a vanilla kernel + voodoo 3-4% an hour drain. Whenever I have my screen on battery drain is insane. 30% increase with the screen on vs how it norally would be. I would recommend flashing ka7/kb1 + voodoo kernel. That should fix it right up.
2 things
Check and make sure there are not background apps engaged when using those apps (sounds like there may be)
Also if you want you can buy a 4g battery it is 1650 mah that will help. But I use my phone alot and Battery really not an issue anymore.
check your background apps see what is not necessary to run.
i believe Team Whiskey removed the OverStock kernel and replaced it with the regualar VooDoo kernel in Bionix-V 1.3.1....
Maybe you should try that....
I'm using Categorically Worthless kernel on Binix-V 1.3.1 and my battery life is great
I must say THANKS as well. Tried rooting yesterday but something went wrong, was on official 2.2 and couldn't get 3e-2e fix to work. Nearly bricked phone. Searched xda. Now rooted with Bionix v (not tw version). Loving this speed. Battery isn't an issue since I have a spare w/charger.

Go to team whiskey's website,register,go to forums look for shory's files near top of page download kb1+voodoo kernal and flash it w/clockwork ...that will overwrite the over clock kernal and give you much better battery life or you can just flash bionix 1.3.1,personaly i like 1.3 and i just switch back and forth between kb1 and overstock it only takes about 20 seconds to flash
Bionix-V 1.3 w/a Splash of Color
Thanks for the response everyone. Will flashing the kernel wipe everything? I will be doing a backup though clockwork anyway. I was just wondering..... Thanks.

No, it will just overwrite the kernal files, so your sd card and all that should be fine, but go ahead and get in the habit of making backups regularly. Trust me, it can happen.
Hi there. There seems to be a number of tweaked ROM's for the Aria and unfortunately, I'm not tech savvy enough to understand the different kernels. From your personal experience, which ROM gave good battery life on the Aria?
I'm currently running CM7.0.0 and usually gets a day with normal usage. I'm willing to drop down to froyo if it means more battery life. Any input would be awesome.
if you use setcpu just flash my kernel as it has lower cpu speeds and no need for a screen off profile

Can you flash the kernel on any ROM? Do you lose any data? SetCPU bottoms out at 246 for me right now, but I know I've seen others here at lower. I'm running FR008.

Just because it's gingerbread doesn't make it awesome. Still has its downsides. 2.2.2 and fr008 have been so refined its stupid. I get the best battery life out of those. Setcpu with 2.2.2 gives me a warm sensation.
Sent from my HTC Aria using XDA App
CM7's battery life, when the GPS libraries aren't forcing the CPU to 100%, is good. A day or so. Maybe more.
2.2.2 is a little over a day on average, and CM6.1.1 can go up to as much as two days. So CM6 is the winner with battery life. But it's Froyo.
I'm getting two days with moderate usage with FR008...

By 2.2.2 do you mean Gene Poole's hfr003b? Do I just flash that as a ROM or are there other kernel or settings things I need to flash? There seems to be a lot of zips on his post. Sorry for my noobness

Flashing the ROM is enough. It comes with a kernel that will let you overclock only while you're using SetCPU. If you don't use that app it will run like a stock kernel and will give you great battery life. That's my choice and I'm happy with it.
Cool. Thanks everyone.
Hello, Just thought I would post my stats using the new Starburst rom with Pershoot's Kernel. Getting great speed and the system runs very smooth but it feels like my battery is draining quite abit faster...
I have setcpu set as "OnDemand" 300mhz-1400, 256mhz when screen is off. Is this battery drain normal? Ran for 4 hours idle while working, then during break i used my tablet for about 15 min, idle another 4 hours and then after work I only got about 2 1/2 hours of use from my tablet before getting the 15% battery warning (79% to 15% in two and a half hours).
Before installing any TW rom and using Pershoot's older (non-TW) kernel with same settings I was getting atleast 4 hours after having the system idle all day while i work (10 hrs), this was with about 40%+ battery left to spare. Please take a look at my stats and feel free to give any suggestions to help me get more battery
The performance now is very good, but before TW i was getting about 150 less points in quadrant (2950ish)with the extra battery life. Also i dont let any apps run wild while idle and have gps,bluetooth,wifi turned off during working hours.
Quadrant Score, Starburst TW + Pershoot's Kernel Aug/9/2011 builds (score:3100).

Battery Stats, notice the steep drop at the end? Thats the only time I really used my tablet... about 2 1/2 hours, web surfing (14 hours 35min total on battery).

why is your screen on and awake bar completely full if you only used it for the last 2:30?
In GENERAL
Screen on time 8-10 hours
Standby time ~100-500 hours depending on whats on/apps installed.
No idea why it says the screen was on, it was not... And I had the unit on but as far as i know there isn't a sleep option so the unit was awake but not being used.
If you know of a sleep option please let me know, thanks for your reply
Yeah I'm still testing this exact rom/kernel combo and there is something up with it.
On a reboot, does the battery level go up? Does it stay up for a little while then drop back down?
Also have you done a battery calibration? If so, how?
I'm just trying to narrow down what could be causing the problem. I'm no dev by any stretch of the imagination, but for some reason I really want to find out what is causing this. It doesnt seem to affect all machines so in finding the simularities of those that are having this issue, we can squash this bug....
I was using this combo and my google music kept force closing.
Sent from my ADR6400L using XDA Premium App
it should goto sleep automatically, and if screen was off it should be indicated as off. maybe something is wrong. im currently on pershoot's kernel as well and have had some issues with battery calibration (reporting bogus stats).
i think pershoot is looking into the issues on his thread.
im using 10.1-Wifi, Touchwiz UX (OTA, GT-P7510)
It's a kernel problem. Try going back to stock or an older version of pershoots.
It'll be fixed today from what I've read.
Late last night reinstalled Starburst with its original rom, after my 10 hour work day it still has 95% battery left (after some galaxy on fire 2 during my break), hella lot better than it was yesterday.
I will wait for Pershoot's revised kernel and test it out again. And thanks again for all the devs making custom roms and kernels! Much love to ya! <3

From what I've read, he claims there is no problem with the kernel, the problem is with the user. We havent calibrated the battery correctly according to pershoot himself. Problem is, I cant figure out the secret to a correct calibration process....

Flash Starburst or stock rom then charge your tablet 100%, once your battery is fully charged flash Pershoot's kernel.
I have not tried this myself but from what I have read it works, right now im happy with the performance on stock Starburst kernel, quadrant is at 2300 compared to Pershoot's 3100 but its running so smooth I cannot notice the difference. Going to wait for Pershoot's reworked kernel and then flash it, I gots to have my voodoo!
Update:
Today I reset my battery, and installed Pershoot's kernel. I'm still getting battery drain, used for 5 min this morning and its down to 80% (just browsing web)... Also my clock got stuck at around 5:08am and my alarm did not work this morning until i turned my screen on. After I installed Pershoots kernel alot of apps were acting up and not running properly but after a reboot my clock and apps started working as normal.
And I have to hit/hold the power button like 5 times to turn on the unit now. Going back to original Starburst for now.

android system shows up after a call guys...Make a call and see what happens but that does not have to be the battery killer. It can show up on mine like crazy and I still get good battery life. Change kernels, drop processor speed delete apk's from system/app that you dont need and may be running. I mean there are a lot of things you can do expect panic.... Its ok give everything a shot you will work it out...
Oh yea change it from smartass to something else, you got choices what may be good for one person may not be right for you....
I just don't know what each scaling does or how it effects my evo. I just went with interactive for the time being.

So my N7 arrived two days ago, and I immediately unlocked, rooted, and flashed some things. Currently running Codename Android with Trinity Kernel.
My battery is absolute crap now though. Its been two days so I thought the battery more but have settled by now. All auto sync off, brightness at lowest setting, apps sync every 4 hours, still bad! Does calibrating still work? I read somewhere that it was debunked and it didn't work. I would appreciate any help. I mean, my Maxx is getting better battery life.
I uploaded some screenshots of the battery after only 1 and a half hours.

Go to the motley kernel thread in Original Development. He provides a mirror link for the stock kernel
I loved Trinity and the TKT app but for some reason im getting much better battery life with motley kernel. I originally did some troubleshooting and fixed some apps that were causing wakelocks. My battery life got a little better but not by enough (could only get 3 or 4 hrs screen on) so i switched kernels.
If you feel like experimenting do this:
Nandroid
Wipe Cache + Dalvik
Wipe System
Factory Reset
Flash CM10 nightly (any rom of your choice)
Flash GApps
Flash motley kernel (i used the 484 GPU version)
Fix permissions
Reboot
I get awesome battery life now and performance is great.
Your title should be something like this: "After rooting and installing battery draining rom and kernel I get bad battery life on my N7"
Stock JB and kernel should yield decent batter life.
With the proper rom and kernel the Nexus 7 easily match or better the googles battery life claim.

I wouldnt go as far as saying its a battery hog, but i ran the kernel at stock clocks and while performance was much better than stock i still had tons of drain that i now dont have with a different kernel.

Get off those custom Roms and kernels until you understand how the device is meant to perform.
You appear to have 87% after 1.5 hours, that equals about 10 hours, how is that bad? I get about 8 hours if I am intensely playing with screens, apps and games, 2 days if I'm not doing much. Loses 2% at night with wifi off. No root.
trinity kernel and the pure aosp rom, at 1150mhz. id say not bad at all..
Trinity Kernel is a good kernel. I went overboard by saying it was a battery hog. I did have it overclocked up to 1500hz on-demand and it ate up battery faster then I would like. But this is with the newest one, a few of the older ones worked out better for me though.
