No way in hell you can judge battery performance 3 hours after flashing. That being said, I have been using this kernel for a couple days now and I average 5% battery loss per hour with moderate use (calls, email, music player, web.) I think that is pretty good.
[Vibrant Android Development] phrozenflame:
You are absolutely right, I'll test longer :) and i'll modify the post.
[Vibrant Android Development] Globespy:
Yes, ANOTHER battery related comment....

I know there are differing opinions on battery life, with many stating that it's a smart phone and should be expected to use battery quite heavily...however it's crystal clear from using previous ROM/Kernel combinations that the Vibrant can actually be very conservative on battery consumption whilst still doing all the things it was intended to do. I recall on ROM's such as Nero5 (superb life!), Bionix-V and M-Flagship that with a stock voodoo (not voodoo sound) kernel, I had seen my phone stay off the charger for 2+ days with light/moderate use.

For those that say 12-16 hours is acceptable, I say check the history and see that this kind of battery level pales in comparison. Not my opinion, not here-say, there's plenty of documented cases of excellent battery life well beyond the 24 hour mark. And sure, I could always go back to those ROM's but the question remains, if we know more about the system and it's code now than we did back then, why hasn't the battery life gotten better instead of worse? It doesn't make sense unless froyo is itself the culprit and not as nicely coded as it's predecessors?

That being said, I've been running this Kernel (V1.3) on Bionix 1.3 with KB1 modem (by far the most accurate GPS for me) for a few days and still think that it is kinda heavy on the battery. I followed usual guidelines and reconditioned battery stats after allowing the phone to perform at least one full discharge cycle.

I am using a slightly larger 1800mah battery (20% more capacity than the stock battery)

I have SetCPU set as follows:

CPU: 1000/400 (on-demand)

Screen Off Profile: 800/200

Additionally I have full version of Total Screen Control which I use to seriously dim my displays brightness (universally across all apps including web), and run on an almost totally black wallpaper to further conserve battery.

I unplugged this morning (after charging all night) at 8am and used the phone fairly heavily for about 4 hours - I would say I spent around 2 hours on web, and maybe 15 minutes of phone calls plus 15 minutes of Google Navigation

Battery was at 44% - that's kinda harsh especially when I'm working on a screen that is significantly dimmer than even the lowest stock brightness settings.

In my opinion the Overstock Kernel is better than the Dragon kernels, but it's still a lot heavier on the battery than say stock KB1+voodoo kernel.

I love the Voodoo sound, although it's tricky to justify sticking with this kernel when Galaxy Tuner does a pretty decent job of improving the sound, although of course not on par with voodoo sound. Additionally Galaxy Tuner has some nice memory management settings that further increase battery longevity.

I thought the drop of the official froyo source would provide developers with a way to engage the sound capabilities of the Vibrant without all of the negative battery constraints of the i9000 kernel source that plagued the Dragon ROM's in terms of battery life.

All good food for thought, and there are some very smart minds working on this stuff.
[Vibrant Android Development] EricDET:
I've been using this with Bionix 1.2.1, 1.3, and now 1.3.1.... In terms of battery life I would put it a notch above stellar... Especially when compared to any other non-stock kernal. My battery lasts forever.
[Vibrant Android Development] Globespy:
More info please......define "stellar" and describe your average use.

I'm assuming that you are finding that your battery lasts a lot longer than what I detailed, but specifics would be nice to justify your experience.

Cheers.
[Vibrant Android Development] OldeCrow:
I would say the battery life with this is much better than the stock kernel, you really can't do much without the setcpu app from the market but with the app you can setup profiles so for example a screen off profile with the cpu running at 400 instead of 1k should save a lot of battery and a normal profile at max speed of 1k So far it appears to be be a huge improvement over stock. and it still scores nicely on the benchmark.
[Vibrant Android Development] Globespy:
Interesting.....seems that I'm using the same SetCPU settings but as you can see from my post on the previous page, not quite enjoying the same battery life as you seem to be, despite having a 20% larger battery!

Can I ask what ROM you are using?

Thanks.
[Vibrant Android Development] cmenard:
I had a calendar widget that I updated via the market over the weekend that was causing all my problems. Once I removed that app my battery life was back to normal. Both my phone and my fiance's are running with BLN and only last ~1% per hour overnight. That's exactly where our phones usually are. Once she saw BLN in action last night she wanted it too ;).

I wish Sammy would hurry up and return my other Vibrant so I'm not doing so much testing on my daily.
[Vibrant Android Development] Globespy:
Thanks for the update.

Can I ask if this would essentially be the same as me renaming the BLN system/lib file with .bak at the end? I saw this posted and was the first thing I did after flashing the kernel to ensure that BLN was disabled. Yet, still iffy battery life...unless using a browser on a very dim display for 2 hours is expected to use almost 50% of a fully charged 1800mah battery?
[Vibrant Android Development] kcp877:
Best post I read all day. Shoot me a link ill test with you! I've been waiting for this since sonique removed hers without the blind battery drainer
[Vibrant Android Development] MINUS Stl:
FWIW, I had 39 1/2 hours on 1.2.x the other day before my phone turned off. That's with BLN enabled. Definitely interested to know the results of the non-bln kernel test.
[Vibrant Android Development] Globespy:
39.5 hours with overstock kernel and BLN? SERIOUSLY?

What ROM are you using?

Did you have your phone completely unused running in a cryogenic time-warp?

Or perhaps you have a hydrogen powered battery you haven't mentioned?

2 hours of web browsing plus some calls and light nav use killed over 50% of my battery with BLN disabled.....so excuse my surprise in what you just posted.
[Vibrant Android Development] OldeCrow:
I was running Bionix 1.3+ fix with the ka6 modem and the 1.2.1 kernel with setcpu. This morning I flashed to Bionix 1.3.1 with the ka6 modem and the 1.3 kernel with setcpu, still seems to have the long standby time as my battery is still on 97% after disconnecting from the charger and hour and a half ago and 97% is where it dropped to when I unplugged it.

I have noticed with the latest rom and kernel my home button is stubborn to long press for the task manager, I suspect this has something to do with bln but it may just be coincidence!

@cmenard

I don't usue BLN myself so I will be just as happy with your kernel either way!

oldecrow goes looking for the thanks button.......
[Vibrant Android Development] MINUS Stl:
I was running Trigger 2.6.3 (now on 2.7). IMO, OverStock and Trigger make an amazing combo. Usage (I'd consider light) was over the weekend with texting, calls, Twitter (Plume) and some puzzle games. Didn't do much web browsing since I can just jump on my netbook while at home.

On a side note: I do use Juice Defender to turn off data/wifi while the screen is off due to my connection while at work. Battery would tank due to the phone constantly trying to connect.....but that's at work. :)
[Vibrant Android Development] Globespy:
That makes more sense now......I'll assume that your phone is not accessing data at all for 8-9 hours per day...that makes a heck off a difference to battery life :)

Interesting about Trigger...heard a few folks say that Overstock+Trigger is a good combination....I'll give it a try.
[Vibrant Android Development] kcp877:
I vote for a release tonight! Love this kernel hate the bln drain.
[Vibrant Android Development] defconoi:
I get 30+ hours with lots of usage as well after recalibrating

Sounds like your battery sucks or your using allot of cpu with high brightness, mine is set to 0
[Vibrant Android Development] Globespy:
thanks for your reply. I suspect its down to individual versions of what is light/heavy use.

Can you try (time permitting) using your browser continually for at least an hour and tell me what happens to your battery? I'd be interested to see the results....

As far as brightness, I use a program that had my display dimmed quite a bit below what the minimum is on the vibrant stock brightness control.
[Vibrant Android Development] mystycs:
Is the battery better than KB1 Stock? And do i need to use setcpu for this? Or is setcpu only if i want to overclock it?
[Vibrant Android Development] mystycs:
Avatar does not work with overstock kernel yet kb1 does. Fyi
[Vibrant Android Development] Globespy:
No, KB1 Stock or any other stock Voodoo kernel will be better battery.

There's debate that this is not the case and some newer voodoo sound kernels are on par with stock battery, but there are a lot more folks saying the opposite to this than those who are sticking with this story.

I change ROMS on average once a week (sometimes more if there's new stuff available) and have noticed a much larger drain on battery using a voodoo sound/OC kernel than a stock one.

I use my phone a lot....like using the browser for hours at a time, so I get to see what heavy use looks like on battery level.
[Vibrant Android Development] InversedTech:
I flashed Bionix 1.3.1.

About two hours later, I flashed Overstock 1.3.

I'm stuck at the Overstock boot screen.

Yes, I flashed through Red Recovery.

Anything else I could have done wrong?

I have to Odin back to stock now, ugh.
[Vibrant Android Development] lolcopter:
Did you clear cache / fix permissions before rebooting with the new kernel?
[Vibrant Android Development] InversedTech:
I'm a noob to flashing kernels.

So, I did not.

Was I supposed to?
[Vibrant Android Development] xtone:
heh.. i just flash and reboot. no issues.
[Vibrant Android Development] InversedTech:
Yeah, that's what I thought was going to happen.

But I guess not.
[Vibrant Android Development] jaetm83:
cmenard,

My battery life with OS 1.1 was not bad at all although I didn't have it on my phone long enough to measure how battery life looks like.

But when Bionix-V 1.3 was released, I re-packaged it with OS 1.3. I also replaced lights.s5pc110.so included in your kernel with much older ~10kb file found in Bionix-V 1. And I excluded BLN app to begin with.

I am getting ~1.8% drain per hour in sleep with wifi on 100% of the time. I have a few apps set to update every half or a quarter of an hour.

Hope this helps knock down where the excessive drain others are seeing is.

EDIT: Just wanted to add, I am enjoying Voodoo Sound with no other things to worry about because you made this kernel. Thank you so much for your work!
[Vibrant Android Development] BuLLeT_PrOOf_wAlleTz:
Awesome battery life!! Unplugged at 8am, at 1:45am was at 49 %

That's with bln
[Vibrant Android Development] cmenard:
It seems the issue is with the included liblights.so file and the noled application.

All the phones in the house are BLN enabled now and seeing normal battery drain. Last night both lost ~1% per hour like normal. My problem was a calendar widget that worked well in the past, after I updated it from the market over the weekend it was constantly refreshing my calendar. Removed it and all is well again.
[Vibrant Android Development] domtru:
Download last night. I will check back later with battery report. BTW, this is fast!
[Vibrant Android Development] kcp877:
So no update to a liblights free kernel ?
[Vibrant Android Development] thechadhall:
flashed this yesterday with bionix-v 1.3.1 with xtone's blue overkill theme. seems to be running great. will update as the day goes about battery life.
[Vibrant Android Development] reddragon72:
Uninstall WIFI calling. Install the latest kernel here and then boot. let the phone set for 15 min then reboot. Now using the bloater app reinstall WIFI calling.

On Trigger 2.7 WC(WIFI calling) worked fine. When I installed the latest kernel from here it FC's when receiving calls. So I rebooted, no change. uninstalled WC and reinstalled, no change. Finally just uninstalled WC and the OS kernel and rebooted, waited reboot, reinstalled OS kernel then wit 15min reboot install WC(via bloater) then it all worked. No more FC's, at least for today.

I cannot do without WC so I had to get it working some how.
[Vibrant Android Development] reddragon72:
I'm throwing this in a separate post because it needs it.

This kernel tied to Trigger 1.7 is stupid fast!! I have been running the KA6+Voodoo with the stock KA6 Kies download and thought that was doing well. This is incredible! Even the battery is WAY better then before. I have all my old apps loaded and running and it is snappier and way quicker running them all. With my old ROM, KA6 stock+voodoo, I would hit 60% battery from 8AM-noon with WIFI on and WIFI calling running and maybe 2 5min calls and 3-6 txt messages no games no app usage, just the phone setting there. So far today I have hit 80% in the same time frame. I say that is not bad. It used to be that by the time I got home at 5:30 or so I would be down to 25% even with a battery conditioning.
[Vibrant Android Development] crunkhead18:
does this kernel works on Trigger 2.7?
[Vibrant Android Development] Romanbb:
yes it does :)

Okay guys, so I tested it again, after a complete charge.

I went from 100% to ~34% in 26 Hours. During this time, It was normal office usage, calls, a few msgs, gaming for like ~20 mins in between, however, I kept WiFi on deliberately (did not connect tho) through out this time period. I kept Data network off as I usually dont need to use it at work.

My Quadrant score: 1816. (Screen sometime later)

Im on 2.2 KA6 Vodoo stock.
[Vibrant Android Development] mr.haqeem:
me too..for the 1st time i got this problem. it must be something with this kernel. didnt want to wake up (sleepofdeath). :mad:
[Vibrant Android Development] z3NN9:
I thought I was stuck and just let it sit and it eventually went to the trigger boot for me.

I've also had a couple of random reboots and one camera lock up on the 341mb version.

Just flashed trigger 2.7 and will see how it goes..
[Vibrant Android Development] mike216:
im running bionix 1.3.1 and this kernel is very good for me after a couple reboots and a overnight charge it will get better give it a chance i noticed that if you give kernels a little time sometimes things smoothen out some hope it works out for you
[Vibrant Android Development] z3NN9:
I had been running 121 before and had been having good luck until today. Updated to 1.3 and trigger 2.7 after this stuff started happening.

At this point I'm still not ruling out that my refurb replacement is junk lol.
[Vibrant Android Development] domtru:
I flashed it, is very fast but battery life drains fast. I thought nothing changed on my "about phone". It says overstock on startup and the quadrant definitely reflects that I made the change. Can someone confirm that this is the kernel/baseband that is supposed to say? Thanks!
[Vibrant Android Development] parmijo11:
All I can say is DAMN. 1953 is impressive on a non OC'd kernal. I average between 1825 - 1875. Running on Bionix 1.3.1. Well done!
[Vibrant Android Development] takato23:
how do you reaconditionate your battery?

i'm only getting 4 hours of battery with darky 9.3 and this kernel.

The way i reaconditonate battery is wait until battery gets to 0, charge to 100%, turn on in recovery mode, wipe battery, reboot, unnplug
[Vibrant Android Development] copter105:
How come when I click to download this it goes to a blank screen and does not download? Where can I get it? Is there a mirror site somewhere?

[Vibrant Android Development] mike216:
Just go in recovery/advance/wipbattery stats/confirm/teboot
[Vibrant Android Development] mike216:
Go get setcpu from the market and set a profile on it so when the phone sleeps you can set the cpu to throttle down you will get you better battery life
[Vibrant Android Development] z3NN9:
battery life has been excellent, its the camera lock up and random reboots that worried me ;)

[Vibrant Android Development] crowlaw:
So I have never used OverStock kernels, or any other for that fact before.

Currently have Bionix v1.3.1.

Will OverStock v 1.3.1 put any additional strain on my phone's hardware? In Bionix's OP he mentions the use of OC kernals do that.

I have always wanted to try out OverStock, but I am just worried if it does in fact put additional strain on my phone, if that is even the case. If not, I really want to try this out.
[Vibrant Android Development] GTOJim:
OverStock isn't for overclocking your phones CPU, it's

based on a stock kernel with some extra features added. It's not going to put additional strain on your phone.

OC (overclocking) kernels are another matter. OverStock is not a OC type kernel.

Hey ppl here, how is the voodoo sound working for you? Whatever I did voodoo control app makes no difference to my music listening experience (on stock music player). I had read rave reviews about voodoo sound, not sure if I am doing something wrong. What settings are the best for overall sound quality?
[Vibrant Android Development] Danielpc:
I think it is awesome. I use it with all music apps. I'm going to assume you have this kernel flashed. I do not bother with the force analog vol key option. I set the media volume to 100% and manually set the headphone amp as needed. I also have anti-jitter and hi-fi play/record selected. In case you did not know, it only works with the 3.5mm jack at the top of the phone. There will be no difference with Bluetooth or the Samsung charging dock.

Update on Battery

Ok, so I posted a couple of days ago that the phone pretty much used 50% battery after I had been using the browser for 2+ hours plus a few calls.

I've done some more testing, and the interesting thing is that the battery life when the phone is not being used is INCREDIBLE. I happened to not use it much these last couple of days and it would have gone 2+ days (after 1 day 12 hours it was still at 29%) if I didn't stick it on the charger to make sure I had juice for today. Clearly the coding of the kernel plus addition of setcpu settings and disabling of BLN creates an amazingly conservative kernel while the phone is idle!

However, under use it seems to chew through the battery quite a bit quicker than previous kernels.

Before anyone flames with a smart ass comment about how it's obvious the phone should use battery faster when being used, please consider that I'm testing it's effectiveness under use. None of us want a phone that is never used, so the usage part is where I'm keen to find out why it burns through so fast. I'm wondering if it could be Bionix 1.3 and this combination that is voracious on battery life under use, as I did read that folks on Trigger seem to be very happy with the battery life.

Just some observations, has anyone else experiences this?
[Vibrant Android Development] xsteven77x:
After the catastrophe of trying dead horse this morning on my bionix 1.3 ( flashing the ****ing KERNEL wiped my phone AND the sd card so could not even restore from backup), it makes it even more clear to me that this is by far the best kernel for the vibrant right now.

It does that evertime you reboot your phone by design. Supercurio plans to change that sometime in the future I believe

Overstock v1.3

i don't use BLN though, because i hate that it comes on for emails. so i just leave it off.

battery life seems sufficient, dare i say -- really good?

thanks!
[Vibrant Android Development] GreggoryD502:
Im happy to report that I flashed this kernel for the second time today. The first time I flashed it I think I didn't let it settle in before using it. I was giddy what can I say. This time I waited about 20 minutes after flashing then I rebooted and waited another 15 or so. All is well on my phone. Very snappy. Bench marks are higher. Thanks for this kernel.

[Vibrant Android Development] chadhoard:
Would just rebooting into recovery be ok?
[Vibrant Android Development] GreggoryD502:
You don't have to turn off voodoo. Download and place on your internal sd card. Then long press the power button and go to recovery. Select install zip from sd card. Then choose zip. Then select the overstock file. Choose yes. Then after it flashes select go back from the menu that pops up. Then select reboot. Then wait a good 15 minutes then reboot again.
