[Captivate Android Development] :
Thanks for the fast reply.

Is 'K' good, of should I stick with 'I' since a lot of people seem to like I and have been saying that I is good with battery?
[Captivate Android Development] q5ypdg9:
I'm currently using K12K, but I agree that battery life seemed to be better with K12I - I retained the zip file just in case I want to switch back.

I am running Phoenix 2.5; Modem JK4
[Captivate Android Development] hardcore:
There's no difference in the code between I, J and K that could affect the battery. So I think it's just the usual case of the battery meter being inaccurate after flashing.

It's best to use it for a few days to see if there's really any difference in battery life.
[Captivate Android Development] XGX5309:

I've been wondering if it's possible to bump up the output volume levels. After using AudioBoost, I know it's possible, but maybe with a custom kernel it's possible to do it without having it put such a strain on things. With AudioBoost it's quite noticeable, especially if you have a live wallpaper running.
[Captivate Android Development] :
Cool thanks. Do you feel that this Speed kernel is better than the Firebird kernel that came with Phoenix?

Ahh, thanks for the info. Ive used the Firebird kernel now for 4 days, hoping that it would straighten out for me, but its still killing my battery awfully fast. I think Ill try K and see what happens. Thanks.
[Captivate Android Development] bamonkey:
Never seen too much of a change in battery life between versions. Just put on "J" 500hz version the other day so heres my current.. 16 hours and down to 82% ...you wont see me complain:D.. and this is after the 98% percent full charge bug everyone is talking about in the 2.2.1 roms.

Going to move to K as things did feel a bit weird on the audio in J. Thanks Harcore for keeping it up over here for us captivate people:p
[Captivate Android Development] Majortom420:
The first thing I notice almost immediately is it's not as fast as Voodoo, however I'm going to test this and report back on the battery life, thanks.

Anyone experiencing non-restoring network connection in low-coverage areas with new K12K?
[Captivate Android Development] Clienterror:
I have noticed this as well, but the battery life is litterally 2x as good. IMO it runs smooth enough to not be an issue.

Bluetooth Headset Static

I Have Flashed This Kernel Over Cognition 2.3b8 And Have Tried Every I9000 Modem. I'm Now On JK4 And Still Have Static. I Have A Samsung WEP870. Is There A Fix For This??? :confused:
[Captivate Android Development] simulatordos:
You need to ref lash to stock and install a i9000 rom like perception. You cant use a captivate rom with an i9000 modem.
[Captivate Android Development] delugeofspam:
Have you tried the TLJL3 modem? Also see if the headset itself has a factory reset function, and use Titanium Backup or a similar program to wipe the user data from "Bluetooth Pairings," then reconnect it.

This simply isn't true. There are several people, myself included, using this kernel with the latest Cognition, a Captivate ROM. I can tell you that the JJ4 Captivate and T959TLJL3 modems both work well with this kernel/ROM combo. I can't speak to bluetooth functionality as I've only used the OEM headset thus far.

Posted from i897/Cognition 2.3b8/speedmod k12k/T959TLJL3 using XDA App.
[Captivate Android Development] eep2378:
Same here I experienced more idle drain on J. So I went back to I.
[Captivate Android Development] hardcore:
You should only make a final judgement on battery usage after a few days' use, because the better meter can be very inconsistent.

Anyway version K is significantly faster than any previous version because I stopped using the bfq scheduler.
[Captivate Android Development] ngochuy:
r u serious? My battery is only less than 1 day. Which rom are u using?
[Captivate Android Development] derechbennoach:
I looked did not see anyone with this issue.

I install using CWM, install rom menu selection. On the recovery install it fails with a verification issue.

I power off. I restart and it installs just fine on the reboot without intervention?

What am I doing wrong?

BTW great battery life. I have lagfix off and it is fast enough for me.

[Captivate Android Development] jaxf250:
Not sure if this is old news to anyone, but whenever I update my kernel (be it speedmod or others, but lately all I use is speedmod ;-) I have to go back into the WiFi settings and re-check the box that tells WiFi to goto sleep when the screen shuts off. For some reason, each time I update my kernel this gets reset to "Never" turn off and I have to re-tick it - no big deal, but thought I would mention it for those wanting to stay on the latest kernels (H, I, J, K) and ensure they are getting the best battery life they can after each update. HTH someone. :cool:
[Captivate Android Development] RonH54:
I am sure this is posted somewhere but hope you don't mind if I re ask. I am using "i" version and it the only Kernel I have Flashed. If I try "k" do I have to reset the 'Tweaks" and should I recalibrate battery and wipe battery stats?

Thanks
[Captivate Android Development] RonH54:
I am having a weird problem with the WiFi Sleep settings. I go to Spare Parts app and when I check the Wifi Sleep setting there it shows none of the 3 options checked at all. So I "check" the Android Default option and it Highlights to Green so it on. But if I Power Down the Phone or reboot and go check Sleep Option again nothing is checked and I have to redo. Does anyone else have this Problem? I am using Ported Darky 8.0 ROM on my Captivate and it may be a Darky issue and I will ask at that Forum also.

Thanks
[Captivate Android Development] delugeofspam:
If you're flashing at full charge then no to both questions.

If you don't flash at full charge you might get some unpredictable battery drain but it should even out anyway.

Recalibrating never hurts.
[Captivate Android Development] RonH54:
Thanks for reply. I know this a stupid question but does it hurt to Flash or do anything in Recovery with the Phone plugged in and charging?

Thanks
[Captivate Android Development] existz:
No, it doesn't hurt anything
[Captivate Android Development] Chillyw:
I flashed to doc's gingerbord edition yesterday, and decided to try the speedmod kernel today. I first flashed k12k 256, but when I held my phone straight up, it would autorotate my screen sideways. Then, when I held my phone sideways, it would rotate my screen to normal.

I reflashed to make sure it wasn't a bad flash, and the same thing happened.

I then flashed k12j 256, and my reorientation is now fine. Not sure if this is a known bug or anything, but wanted to let you know just in case.
[Captivate Android Development] :
Do you have to be at 100% battery to flash this kernel?
[Captivate Android Development] diablo009:
Not just this kernel, but any kernel for that matter. This helps avoid battery calibration issues.
[Captivate Android Development] diablo009:
Did u flash the i9000 version or the captivate version. This happens sometimes when u flash the wrong version.
[Captivate Android Development] silverslotcar:
You don't have to be at 100 percent to kernel flash. And Diablo's right, if your screen orientation is opposite then you went and DLed the i9000 version.
[Captivate Android Development] GTIVRon:
I have my phone flashed with stock 2.2 froyo and its rooted. I downloaded the cwm version and tried using cwr to install it. Booted into recovery fine, but when I went install packages I got a e-signature verification failed error and it aborted.

What happened?
[Captivate Android Development] diablo009:
If I am not wrong, these are for i9000 based captivate ROMs, not stock. Anyways, I could be wrong too.
[Captivate Android Development] double RL:
I don't flash kernels at 100% too often. I never have any calibration problems.
[Captivate Android Development] silverslotcar:
Your on froyo and this kernel is for reoriented roms. Stock 2.2 JI6 froyo for the captivate isn't gonna be very compatible with this. But that isn't even your biggest problem. Your trying to use reinstall packages in regular recovery. Thats NOT how to do it. You have to go in rom manager and FLASH CLOCKWORK RECOVERY (this puts the alternate recovery as an update.zip on the root of your SD) then boot into regular recovery then hit reinstall packages (might have to twice) then you should see CWM recovery (green text) then install zip from sd and navigate to whatever zip you want to install. Just bcuz ppl root with reinstalling packages they all think that this is how to install zips, well its not. Hope this helped.
[Captivate Android Development] erickgoldner:
Uhm, prob dumb question:

When you guys says that you have 36 to 48 hrs i suppose that you don't let the data plan (3G/H) or even Wi-fi on the all time, right?
[Captivate Android Development] silverslotcar:
Cell standby shows the data in the battery usage. And since wifi isn't on there, that means he isn't using it.
[Captivate Android Development] diablo009:
What theme/ROM are u using? I like the battery mod.

Good God this kernel is FAST! Ill have to test out the battery life, but even if its at the same, I just got faster.

I applied all of the reccomended tweaks and converted to ex4. So far, ex4 seems faster than voodoo. Thanks for an awesome kernel!!!
[Captivate Android Development] silverslotcar:
Voodoo also converts everything to ext4, so they are basically the same lagfix.

I'll have to search for help on using ADB/what it is. Thanks!

Also, is there any way to flash a new ROM using ClockWork ROM app? And will doing this make me not use 3e, but something better instead?

Thanks again!
[Captivate Android Development] existz:
Instead of using ADB, you can set /system RW with root explorer or download SGSTools, it will let u mount system RW..its easier..once u do the above, it replaces the 3e with a modded one so you can use rom manager to flash Clockwork recovery
[Captivate Android Development] joeshmoe08:
Does applying laGfix decrease battery life in any way? Just trying to get more juice. Would rather have more bat life than speed (to a certain level)
[Captivate Android Development] existz:
No, ext4 uses same amount of battery or possibly less, than RFS
[Captivate Android Development] delugeofspam:
Alright, I feel like I need to make a point here:

You don't need to use an i9000 ROM. You can use Cognition 2.3b8 with the T959TLJL3 Modem (HSUPA- high data speed/more battery drain) or the UCJJ4 Captivate modem (HSDPA- lower data speed/less battery drain). I've used both, and I'm currently running Cog v2.3b8/speedmod k12k/T959TLJL3.

What simulatordos said applies in MOST cases, but not this one.
[Captivate Android Development] localj:
Hi hardcore,

Thank you for your great work. Btw, can you tell me how to change the kernel boot image?

Thanks so much.
[Captivate Android Development] joeshmoe08:
I think you mean bootanimation and if so just put the bootanimation.zip file (containing the animation in system/media with your pfrefeted root file manager (I use root explorer). Most custom rooms come with one so if you flash this over the rom, the animation should stay.
[Captivate Android Development] joeshmoe08:
Thanks, Btw how much % on average do you lose in standby per hour? How about total bat life including usage?
[Captivate Android Development] existz:
In standby I lose 0-2% depending on modem, jk4 I lose 0% over 8hrs idel, jl2 is 2%... with K12I I had 30% left at 24hrs with moderate use, about 150 txt, had about 5-6hrs of data use, was basically on xda app all day + browser/twitter, had about 1.5hrs of music, about 2hrs ttl in talk time.... thats with 3G/sync=on, wifi/gps/bt=off ... but with K12K im still testing....

But take in to concederation that I have HSPA off cause in dmesg I noticed umts/hspa switching back and forth every 30sec, so turning hspa off solved this
[Captivate Android Development] joeshmoe08:
Alright thanks. I have Hspa off too. I am going to try the jk4 modem again, haunt used it in awhile.

Edit: was just reading your sig loled at "The software said "Install Windows 2000 or Better", so I installed Linux".

[Captivate Android Development] existz:
If you are just using Hardcores startup script speed tweaks, there is no need to use the scripts, you can enable them in CWM, does the same thing...they are actually intergrated in Hardcores kernels...

If you are using other startup scripts you can just name them, for example, S_enable_laptopmode, and put them in /etc/init.d/ ...then the scripts will be launched on startup.
[Captivate Android Development] hardcore:
The tweaks in speedmod are enabled by just going into the CWM menu. You don't have to make your own startup script.

But if u do want to do other things in your startup script, it has to start with a CAPITAL E or S.

You can check /data/user.log to see if the script was run. It might show something there.

Good to know. Sure, with the FASTER setting u get about 1700 Quadrant, but I've tested it and you can lose some data if u hard reboot the phone at a bad time (like when it's booting).

With the SAFER (default) setting you get about 1400 Quadrant, but I doubt there is any difference in real-world speed. And it's very robust - I tested it by hard rebooting a lot, and still didn't get data loss.
