King's Kernel - Input Needed

So I basically have Stock 2.2 with a lot of the unnecessary apps removed. The other day I installed King's 4th Kernel hoping for better battery performance but in the end it's a little worse. I'm not blaming the kernel for my performance issues. But I'm looking for feedback to get better battery life.
Right now I am not using Set CPU. I just flashed the ROM, wiped the dalvik cache, and decided not to wipe the battery stats. I've been using the #4 kernel for two days now.
I work my phone pretty hard every day and have a good idea of when it's gonna die. I don't bother bump charging but rather replace the battery with a spare I have on hand.
Any recommendations to fix my problem?
Try a different kernel?
Get Set CPU? I'm not interested in overclocking but I realize other features are available.
Wipe the battery stats?
One thing I can say for certain is that I've been using this kernel with my current setup for 2 days now and battery performance is worse. Something definitely needs to be tweaked in my engine because I shouldn't have to use 3 batteries in one day.
Again, I want to reiterate that I know there are a lot of factors that affect battery life. I'm basing my opinion off of my past battery life throughout the day. It's probably not the kernel but how I have things setup. I'm just looking for some direction to extend the life a bit.

The biggest thing to do will be setcpu. Underclocking during screen off and using conservative governor will drastically improve battery life.

I haven't ever had good luck with the King kernels on my phone. Adrynaline's Custom kernel has worked awesome for me though. Took it off the charger at 11am yesterday, used it regularily and didn't charge until today at 3pm and still had 32% battery left. I use SetCPU for underclocking the phone when the screen is off and that seems to be the best way to save battery. I also don't have anything syncing throughout the day besides gmail accounts.

Ok, well I guess I will start with Set CPU. Sounds like it's worth the cash. Maybe I'll try a different kernel at the same time.
Thanks.

Setcpu is available for free to xda forum members. Do a bit of searching around and you'll find the link to the .apk

Setting CPU Max at 555 when screen is off took me from 9-14hours to 25-30hours.
Clearing battle stat seems important
I like interactive mode when it seems to be working right. I don't really know what Interactive mode is except that setcpu will show the CPU jumping to differant frequency instead of ramping up like with conservative.

I knew this and had forgotten. Fortunately, right before I dropped the cash the light bulb came on. I appreciate the heads up anyway.
Has anyone had luck with King's Kernels?
srt4mn, do you have a link to the kernel you are using?

The kernel comes with the Virtuous ROM and can be downloaded as a separate entity from ROM Manager in his area.

Ok, cool. I'll give it a shot. Is it tweaked to work just with the ROM or is it safe to install in Stock 2.2 as well?

Clambert11- Sounds as if you wrote your post for me. I haven't tried a custom rom or kernel yet but KK was the what I was considering. I do have setcpu running for a couple weeks now with underclocking for screen off, battery under 50%, and battery under 30%. Have noticed a modest improvement, mostly while phone is asleep at night. Not really much difference with day use. I carry a spare battery and charge at every opportunity.
I'll be watching this thread to see how the new kernel works for you. Sounds like it can be installed over the stock 2.2, yes? Does it require a full wipe?

I just installed Virtuous Custom Kernel - Version 2 without any issues. All I did was wipe the dalvik cache. I'm still not a firm believer that wiping the battery stats does anything. Now to setup SetCPU... I will report back in a couple days.

I tried bump charging with wiping battery stats a couple days ago. Didn't see any difference.
I be watching for your post. I'm happy with my rooted stock. This phone has more tricks than a $2000 hooker. The battery life is the big problem for me.

In regards to wiping battery stats, here's what I do and what seems to work good for me.
This is best to do when you have times when you wont need your phone to much.
1. Full charge phone while phone is on
2. Leave USB/power cord plugged in and turn power on phone off
3. Wait for the LED to change from orange to green while phone is off, this means you have a full charge.
4. Power on phone to get to recovery
5. Go to advanced > clear battery stats
6. Reboot phone
7. Pull out charge cable once your phone fully boots
8. Fully kill phone battery without plugging it in to USB or power the phone until it dies completely
9. Turn phone back on with charge plugged in after battery fully dies and phone shuts itself off, charge till 100%
I also keep my screen brightness down really low, this seems to help maintain good battery life too.

Those are good detailed directions. I had been wondering about when to plug and unplug. I also never fully discharged the battery. Li bats don't have memory issues so why fully discharge? Is the claim that this effects or resets something in the OS? If so where does this info come from? I wonder if someone pulled it out of his butt and it has become doctrine. Did you really see a difference? Did you try something else like lower screen brightness or setcpu at the same time?

i've been running bfs #4 on stock rooted 2.2 for about a week now. loaded the kernel through clockwork. it's working good for the most part and i've been keeping it mostly at stock speeds. however, i have noticed an occasional lag here and there (that i didn't noticed with the stock kernel) but no reboots or lock ups. i'm going to disable setcpu to see if that has any impact.

You pose a good question. I myself dont know the source of the battery stat information, and coming from apple products I've been conditioned to not asking questions, but I can claim from experience that wiping the battery stats help the OS more accurately report the battery percentage.
Since I recently reflashed a new rom and kernal, my discharge rates were rather wonky. The first 15% went pretty fast (as they usually do) since I didn't bump charge. Then it remained normal till 50% when it spiked till 20%, then remained normal till 15% where it took forever to diminish.
Wiping the battery stats will help this number be more consistent since (to me) it helps the OS learn about the battery in conjunction to the kernal being used. I'm assuming that this feature exists because we can swap batteries. Ever curious why apple locks their batteries in their devices? If I had to guess it would be to avoid this whole debacle. They only use one type of battery for each device and as such can report battery percentage more accurately. Plus its easier for them to design.
I've gotten sick of bump charging, so I reset my battery stats after charging to full and not bump charging. This should give me a more accurate drop in battery for the first 15%.
This is all information I've gathered through experience. I do not program these devices, so take it for what its worth. If any Li-ion engineers are around here, help!

Just an update. I've been running Virtuous for a few days now. I thought I installed Custom Kernel v2 but the System Settings say v1. I'll have to look into that. Kinda odd.
Anyway, I also am using SetCPU, which I think is responsible for most of the savings I have received. I've got the default scaling set to Conservative. Additionally, I have a Screen Off profile of 245 max / 245 min in Powersave and a Battery < 10% profile of 806 max / 245 min in Conservative.
I'm still playing the kernel / SetCPU game for the optimum settings but I've bought another 1.5 to 2 hours of life without feeling any real performance woes. I'm hard on the phone and use it a lot. That's what we have them for, right?
I had issues with King's Kernel #4. My phone, at times, would get real sluggish without even using SetCPU. I may try some of his older kernels or his next kernel (when it's released) to see how it behaves.
Just wanted to touch base. Thanks for the previous input and guidance.

Thanks for the update! I think my greatest savings so far has been from a screen off profile at about 460 max. I also have a 50% and a 30% profile.

Starburst ROM + Pershoot's 1.4ghz Kernel Stats

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.

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).
http://imageshack.us/photo/my-images/707/sc20110811003248.jpg/

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
*Stock Starburst kernel is showing my screen being off (when it is off) and my system as not awake when screen is off under battery usage in settings

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.

Hard battery drain could anyone help

I have written this thread about battery drain but it was deleted...
So problem is insane battery drain. I don't know what to do, because i tried everything. This bull**** appeared when I installed firedroid rom with alfs 7 ics kernel. Battery drain was very heavy, after 2 minutes writing sms battery drains 5 percents. it's very much!!! AND SCREEN BRIGHTNESS was lowest, wifi, BT, 3g, sync, all was off
cpu undervolted to 320 mhz. So fully charged battery drain in less than one day without phone using. Is it normal? noooooooooooooooo. I've tried calibration, wiping batt stats, battery saving apps, finally reflashing kernel and rom. But anything didn't help. Now I have x8droid rom with alfs v8 kernel, but battery drain is insane like in previous rom. So what to do? please help me. this **** really sucks... I can't live with this....

Install froyo. <--- Best solution.

but i don't like froyo, there isn't lithuanian language. Any other solutions?

Did you try to reinstall using stock ROM and stock Kernel?
If the problem still exist, i think that will be in your hardware (bad battery maybe)
or you can see your battery health by typing this code in phone dialer *#*#4636#*#* , and then select battery information

What a hell? I flashed ginger jh v5 and alfs v08 kernel, and battery drain is not fixed too!!! Could it be hardware problem? or maybe rom? But i don't think so because i have tried many roms (x8 droid, gingerjh, froyo v3, etc) but there's no difference.

Are you sure that
Data disabled
GPS off,
BLUETOOTH off
Disabled MOCK LOCATIONS
2G Networks
all the time

Make sure you have switched off "background data" and not ONLY " sync.
Switch off both of them.
Switching off both gave a boost to my battery life

if using the stock ROM and kernel you didn't face the problem, i think the problem came with the custom ROM/kernel. so you must tweak your phone to get the best setting for your battery life

yes everything is off 3g gps, all. I installed stock rom and kernel, but the problem exists. since charged to 100, only with sms writing, no internet wifi etc, battery drained to 48 percents in about 10 - 14 hours. Is it normal?
SO IS IT A HARDWARE PROBLEM?? NOT A BATTERY BECAUSE I'VE CHANGED BATTERY TO MY FRIEND ONE AND BATTERY DRAINED AS FAST AS WITH MY BATTERY

It really depends on the number of widgets you use... I seriously doubt if having multiple pages would lead to battery drain.

First don't use cpu at 320mhz it will make phone unstable . Second use Wifi and 3G networks when u really need , not 24/7 . Third look if you have enabled auto-sync(for me is using a lot of battery). Fourth my recommandation is to use Bitdefender Power Tune-up it helps a lot !

Battery drain

Hello!
I rooted my phone as of yesterday, I charged it all night and when I took it off today the battery went from completely full to dead withint 3 hours of no use. I did not use the phone at all.
Any ideas?

If you just rooted your phone, you should not have battery drain... Try to temporarily disable root (with Voodo OTA RootKeeper for exemple)

Use better battery stats to nail down which app is causing the drain

Did you try wiping your battery stats in CWM - advanced?
There's also an app, Battery Calibration, on the Play Store that may help with that.
Not uncommon to get weird battery readings after changing rom's or rooting.

This is soooo strange. Not a normal behavior!! Before you root your phone, how the battery lifes goes??? Are you in a stock or modified ROM? Wich kernel are you using?
I faced this issue a couple weeks ago. Android S.O was the culprit and it was driving me crazy. I was using a custom ROM (RemICS-UX). I solved the problem returning to stock and erasing everything, then i reflashed the ROM and the kernel, in my case Devil3 0.79. If you want to give it a try!!
After that my batterys life is pretty fine, during at least 2 days!
Feel free to ask anything you want! Cheers mate
Sent from my GT-I9000 using xda app-developers app

Go through a couple more full charge cycles, if android os usage isn't very high then, it should be fine.
Edit: on second thought, draining the battery without use in 3 hours is extreme, and would suggest that the CPU is running at max speed all the time. If it doesn't solve itself or improve a lot after a few more charge cycles, reflash everything.
Using GT-I9000 my sent Tapatalk 2 from.

Did you just root your phone or did you flash another ROM? Some ROMs have horrible battery life.

The stock battery usage monitor (Settings>Battery) should be enough to tell you what ate your battery. If it's a particular app you're running, try disabling that and see if it improves. If the usage is mostly "Android System", "Mobile standby", or something like that, then you have a tougher problem. The free app CPU spy will let you know if something is keeping your CPU usage high. Better battery stats is pretty cheap and will give you much more specific information.

+1s for BetterBatteryStats and waiting a few charge cycles before judging/debugging your battery drain, especially if you changed your kernel to root or flashed a rom.
I find that after flashing a new rom or kernel my phone, the battery level shown in recovery mode is higher than in the rom's settings, for a couple days. (You can see batt level in semaphore's recovery). I once dud a lazy search about this and found nothing, but I figure that's what is meant about waiting a few cycles gir your battery to calibrate.

There's no such thing as "calibrating your battery". It's a myth. Wiping your battery stats file doesn't do anything other than reset the tracking of what's using power. It doesn't magically fix your battery meter. Flashing a new ROM doesn't leave left over data, again a myth.
Battery life is never consistent after flashing because your ROM needs to "settle" for a day or two first and during that time your ram and cpu usage are all over the place.
The rest is a placebo effect.

I think I may know what is happening to you as of now. Try to bring up the Battery settings if you are on ICS and take a screenshot and post it here. If my 'spider' senses are correct, your phone did not go to 'sleep' and remained awake.
Since I can't put my signature for unknown reasons...(Maybe because I just created an account since I did not want my old one)

Currently I'm experiencing a huge battery drain too. I used both tools which where mentioned here in this thread and when the drain occours, CPU spy reports that my SGS didnt go in deep sleep at all with turned off display, it was at least at 100mhz all the time! I attached 2 logs from better battery stats and it seems like the NotificationService is causing it?
I'm using JW6 PDA JW4 Modem and JVC CSC in combination with the MNGB 0.5.8 Kernel.

Definitely, now you got to find out what is causing it!

really hoping we get some suggestions here, i'm interested in finding a good combo

ROM is pretty much irrelevant. Features you may enable within the ROM (pocket mode, active display, etc) will make a difference. Kernel tweaks might make a slight bit of difference. But the real culprits for battery drain are apps running in the background and checking for sync updates, screen brightness, and of course actually using the phone. If you have a ton of apps/games on your phone, Greenify combined with a wakelock detector can help you keep them from needlessly draining your battery.
FWIW, I've been using HellSore kernel. Mostly stock settings, although I change the GPU governor to on demand. When idling, I see very little battery drain. When using my phone, battery drains because I have brightness set at 100% and I use LTE. There's no miracle cure for battery life, short of using a bigger battery.

You should test L Android preview. And the best combo I get in kk was purity+ & hellscore kernel. I totally agree with @Planterz.
