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.
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.

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.

Darn. I was just about to give this a try. Oh well I'll try it anyways, nothing to lose. Just remember all the issues that may or may not be caused by the kernel is actually user error

Did anyone try the newest version of the kernel? Posted 19/aug/2011.

I'm using it now & it's a very good finish product. His last version gave me battery issues like no other. I believe he withdrew it after numerous complaints over battery issues.

Working great.
I always wipe Dalvik and Cache before flashing the new kernel.

I will post it once it is 8-10 hrs used...right now only 6 hours...I couldn't sleep much last night lol
edit: argh I just jinxed it, it is now 99% at 7 hours. Will post once I reach 8 hours.

Alright so 8 hours at 98%. I did use the phone a bit while waiting, the display suppose to be 3rd place, after phone idle, normally. Anyways, that is a lot better than 94-92% from before.
My friend who is on same firmware, said that he used music for a hour and web browse for 30 minutes, only used 5%.

Looks promising, thx!

Did you wipe cache and dalvik cache after flash?

could you give an update on your battery stats ?

im not root
stock firmware updated via KIES
no extra wipe
Battery is ok 1d 1h 2m 36s by normal use still 36% left
But Battery Temp seems for me to be higher than in 2.3.3
34°C in 2.3.4 even in idle

my battery temp is 25°C idle, AndroidOS is still present, first charge since the update and my phone lost 7% in 4 hours using it for like 10 minutes.
Not sure if I'll stick with the stock kernel, despite that no major improvements so far, at least none that are worth mentioning (yes, video chat is an option now ...)

Hey,
Can anyone post his build.prop of XWKI4 - DBT
Problem is that my market only shows half of the apps.
I tried clearing cache and data, didn't help. Now I've read about a htc desire user who fixed the market by turning his build.prop to original state (I've modified mine too) - so I wanna give this a try.
Edit: ok i extracted the file myself, but didn't help to fix the problem
Sent from my GT-I9100 using Tapatalk

Somehow this new firmware feels a lot choppier than the last one, for example when moving between desktops.
I wiped /cache and dalvik-cache, didn't help. I really don't want to wipe the data partition.
Can anyone confirm this?
Edit: wiped, still staggering.

Extremely high Android OS use

When I first got my note, the Android OS was listing about 50% usage in the battery consumption. in the last two weeks I have seen that spike from 50% to 70% then 80% and now today almost 91%
I have many of the apps I never use frozen with Titanium and I am very diligent in killing anything that remains when not in use.
The phone is rooted but I have yet to go to a new kernel or new rom. KK1 is my current Kernel and I am on 2.6.35.7
any ideas

Do you mind trying to disable auto sync under Settings/Accounts and Sync? If that doesn't help try do disable background sync too. I suspect the problem lies there.

If you don't charge the phone and then the first think you do is to play a game or a movie then this is normal. I charged my yesterday 100% I did unplugged it and did go to bed at morning, 6 hours later, battery was at 80-85% with wifi on. I did go to work with the bus 1 hour way exact and was watching Dr.house s1e04 after that 10 min of music on speakers and I check battery the os had 71% with 9+ hours out of charger.
Sent from my GT-N7000 using XDA App

not sure what that has to do with Android os usage being so hi. I have turned off sync, makes no difference. Pegged at 91%

I had the same problem in the first firmware. After flashing this kernel the problem has gone.

thank you. I assume if I have CF and rooted, I can simply drop that 1.4 file into drop box and use CWM to flash safely?

No, you need Odin or MobileOdin for this.

well I jumped the gun and did it with CWM. All seems good? indicated its updated. OS use is now in the 30% !!!!

Battery Life BUG in ICS based ROMS

I've done a little research and there is a bug in the 4.0.3 AOSP release. You can see a link to this issue here: http://code.google.com/p/android/issues/detail?id=22878#makechanges
Attached is a screenshot of the problem ocuring in ICS Passion 13.1
I am curious is anyone NOT having this issue?

Yeah, mine started couple of days ago with the same problem. Android System shows 75% battery usage.
I wonder if there is a fix for this bug. I read whatever is on the link but there is all king of possible solutions.

I'm on MIUI and this is happening quite a bit too

Yeah, My battery will be 80% I reboot and it 10% or it's10% and I reboot then it's 80%...lol

I think, 84% is the culprit. Read my post here --> http://forum.xda-developers.com/showpost.php?p=23766036&postcount=2223

I used to have that issue on CM7 many moons ago. Did a bunch of searches and someone mentioned a process call GOOGLEBACKUPTRANSPORT.APK somewhere on XDA, that constantly runs even after you do not choose to backup to google (at least thats what I think its for).
I used root explorer to go into /system/apps and delete the GOOGLEBACKUPTRANSPORT.APK. I have never had any negative effect from doing it. It fixed the Android OS sucking up battery problem. Now I make it a point to delete it after flashing a rom regardless of whether batter drain is there or not. Never had that issue since.
Try it and see what happens. You can always just move it or rename it so you can put it back if it does not solve your problem.

Post to the Google Code bug

Just wondering if there have been any discoveries or new info on this problem.
I was experiencing this bug for a long time and I thought it was a bad battery. After replacing my battery it was still happening.

Battery life is the sole reason I went from ICS Passion (4.0.3) to Slim ICS (4.0.4).
I think battery life is better now, but I've also been incrementally restoring all my apps, ensuring battery drain isn't unreasonably affected with each restore.

I have this same issue! My battery lasted up to a day yesterday and today I had to charge my phone twice. Lasted only 4 hours. Pretty ridiculous I would say! I did try removing googletransport.apk and it reduced my android os to 25% or so from 60% that's about it.

Try using any of the ROMs on Android 4.0.4
EXROM
SLIM ICS
ZenWick
I too was on ICS Passion. I noticed a huge battery improvement when moving to the ROMs listed above (4.0.4 based)

Wow, this worked beautifully, thanks a mil illego.
Installed ICS Passion v13.1 a few days ago and had severe battery drainage, from 100% to 0% in 8 hours after calibration.
Looking at the battery stats I realized that the phone was always in AWAKE mode, with ANDROID SYSTEM sapping like 80%.
After renaming GOOGLEBACKUPTRANSPORT.APK the phone finally went into much needed sleep mode.
In hindsight, I enabled Google "Backup this Phone" during first ICS setup, and this must've tried to connect to the internet the whole time or had a process keeping the phone awake.
Brilliant fix, you made my day, thx.

I was using ICSSGS's 4.0.3 and noticing that my battery was draining pretty quick with little or no use.
I decided to try the Dark Knight 4.0.4 rom and my battery life has pretty much doubled.
No lock screen issues now either!

SlimICS!
I have been using SlimICS and have never had any batt drain issues. Googlebackup.apk is removed by default from this ROM.

I never get good battery life on a ics rom, tried on 3 different phones with 6 different roms. It looks nice but isn't battery friendly from my experience.

You must have one or more apps draining your battery.
User betterbatteryStats or "BadAss battery monitor" to check where battery is being used and whether any app is keeping the phone awake.

I agree
I have to agree. When I use a Froyo Rom my phone loses .5% per hour in idle. At times it loses a max of 1% per hour. However, with ICS ROMs I lose around 1.7% per hour. I have tried just about all ICS Roms, and all Kernels. While some are better than others, 1.7% per hour is pretty standard with any ICS. Trust me, I have no deep sleep issues, and no abnormal wakelocks. I've read all the post of saving battery life, and done them all. Roughly 1.7% per hour is what I get with any ICS Rom.
Personally, I like the look and feel of ICS so I just take the good with the bad. Can anyone shed some light on this. Why does ICS drain battery so quickly in idle vs older android versions. Or, is it just the Vibrant? Im stumped.

[BATTERY/CHARGING] Nexus 4 Issue

Hey XDA,
I am contact you all concerning a issue I've been having with my Nexus 4, The issue resolves around charging and the battery from what I have gather( well affects ),
I have had the phone since the 15th of November 2012, It has never lasted long on its battery even with a stock ROM, I am currently using Paranoid Android ( 4.4 AOSP ),
The ROM is working flawlessly yet, I don't believe that is causing the battery or charging issue, The issue which I am experiencing is extremely slow charging and rapidly depleting charge.
The first think I decided to check was the battery stats/log in the settings, I came across a very odd result.
Here is a screenshot of what a saw.
Can't post links:[ If a moderator could image tag them it would be great:]

puu<dot>sh/5k5sh.jpg
As you can see there is a very wierd spike, I don't know what this is yet I believe it may have caused the condition of my battery to be affected dramatically,
I then decided to check the hidden diagnostics for info on my battery
puu<dot>sh/5k5KO.jpg
As you can see that all seems fine, Hence why I have came to ask the geniuses of XDA for any advice, suggestions or ideas to what the issue is or was.

I'm experiencing exactly the same thing, only just started last night. I'm still on 4.2.2 (CRDroid) so can't be rom/kernel related. Maybe app/play store related?

Maybe, Yet If it was a app it would show up in the battery stats:l

Man why does Google always kill the older Gen. Like tons of people had huge problems with the Nexus S when the 4 came out the phone just died like 100s of people's nexus S didn't even power on. I think Google does so shady things behind the scenes...
