0% drain overnight with 18test.

Had 31% battery when i went to sleep.

8 hours later i still had 31%.

Will see tomorrow if its the same when fully charged.

18test feels snappier also.

Thanks!
[Galaxy S II Original Android Development] Mustoura:
18 seems snappier it looks to behave a little bit better lcd dencity works nicer with 18 deep sleep works instantly all cpu values working when needed now to test endurance of the battery life with 18 .

Hardcore you never cease to amaze me. Fantastic work.

if you're flashing a kernel , then no , you dont need to wipe your phone, neither will your phone be wiped.

but if you're flashing a ROM , then you should follow the instructions from the ROM thread and then flash SpeedMod.

Installed 18 test last night.

Left my sgs2 charging off ac last night. Just woke up and noticed screen was on. Unplugged it

Phone otherwise working normally. Timeout at 15s. Auto brightness. Official uk vodafone kj3 rom.

hitting lock does turn screen off, and menu reactivates it, but then it still doesn't auto dim or go off

never seen this behaviour before

Couldn't notice anything unusual.

K2-18-test2:

- Small patch to ondemand governor

- Updated to CWM5
[Galaxy S II Original Android Development] milan188:
Since making the switch from Siyah I have enjoyed this kernal a lot. With Siyah you need to keep monitoring whats happening all the time. This gives you peace of mind.

A few things I have noticed so far are:

A lot of the kernals I have tried including this one prefer to use the 1200mhz frequency to the 1000mhz frequency. I used the phone for a day with and I did not use apps with high cpu usage. Im sure at 1000mhz the cpu can cope with the load.

I have noticed when looking at battery usage I saw my phone was awake for a large amount of time when the screen was off. When I looked at better battery stats I did not see anything over 5min in wakelocks. I have read somewhere that this happens when there is a Kernal wakelock which BBS does not pick up or the kernal just doesnt go into deep sleep. If it happens again I will take a screenshot.

These small things dont bother me much and I will be interested to know if anyone experienced similar situations.

I went straight from k2-17 to 18 test2 will charge to 100% and report back

What's this patch to ondemand hardcore?
[Galaxy S II Original Android Development] punshkin:
hi

very nice kernel!

over night (8hrs) i had only a 3% drain and this kernel is fluid as i wish!

quadrant 4500 (yeah i know... but Siyah was laggy and gave 1800....)

gonna test daytime use now :D
[Galaxy S II Original Android Development] ukdtweak:
damn, only just flashed 18 test 1 and now there is a test 2 lol...

Going well so far.
[Galaxy S II Original Android Development] :

Good to see such a fast but not rushed development!! Thank you!!
[Galaxy S II Original Android Development] It_ler:
Just flashed SpeedMod K2-18 test2.

And it is definitely faster than K2-17 test1.

Quadrant Standard is now about 4700 points. With K2-17 test1 it was about 4100.

Now testing performance of battery life.

EDIT:

CWM5 recovery now shows the correct progress bar when backing up.

And I can restore my system backups directly from my external sd card.

Thanks hardcore !

[Galaxy S II Original Android Development] AndroidGX:
18-test1 is much more efficient than 17-test1 about cpu idle management, I can clearly see a difference.

On 17-test1 when I wasn't using my phone after clearing all apps on background and leaving the phone at 93%, and when I wake it up after 20 mins, 90% left. Now on 18-test1 when I leave it and wake up it's same percentage even after some apps on background. Great improvement over K2-16-17, clearly :)

Just downloaded 18-test2, gonna flash it on the way and report if t's better then 18-test1 which seems the real winner atm. :cool:
[Galaxy S II Original Android Development] akbarhash:

[Galaxy S II Original Android Development] AndroidGX:
Hmm 18-test2 seems pretty more battery eater than 18-test1, I did almost nothing for 10 mins (downloaded test2 via 3G, rebooting twice, and took a look at Market for 10 secs) and I lost 8%.

CPU idle seems much better in 18-test1 clearly aswell, time for me to revert into 18-test1 which is the best about battery life. I guess that modification (patch ondemand) thing has crashed something about this.

K2-18 test 2 seems to hit 1200mhz whenever opening an app and then drops to 200mhz and K2-18 test 1 will hit 500mhz when opening an app and then drops to 200mhz.

I have tested K2-18 test 1 for one day and I can see the battery saving efficiency is there as it seldom hits 1000mhz and 1200mhz it will only use it when needed. Most of the time it will stay at 200,500 and 800mhz.

I think on K2-18 test 2 the tweak for the ondemand governor makes it open an app faster by hitting 1200mhz but not too sure whether battery saving efficiency will be better than K2-18 test 1 as 1200mhz will use more mv.

I can feel K2-18 test 2 is much faster and K2-18 test 1 but not too sure about battery saving efficiency.

Yes, CWM5 is able to manage and restore CWM4 backups.

Backups seem to be the same, but in CWM5 you have additional options, such as saving the backup to external sd card.

Theoretically, it should be possible to restore a CWM5 backup with CWM4, if it is stored on internal sd card.

Hi guys, I'm using Senstyle rom by Dynamic. its been two days in using speedmod on the rom and Android OS is sucking up my battery! I after following the rom I haven't yet installed most of my applications and still Android OS is taking over 40% on light normal usage! You can see on my photos the major user usage was on music playback of about 2 hours only and facebook,gmail and justreader synced. Note that about 60% time was 3g on, 15% data off rest on wifi. Any idea why Android OS is so hungry and how to improve it?

[Galaxy S II Original Android Development] milan188:
I went straight from k2-17 to k2-18 test 2... I noticed the cpu spent more time at higher frequencies causing more battery drain while using the phone. I switched to test1 and the cpu times are are lower. From 100% to 90% took almost 1 hour of on screen time. With k2-17 I was getting 45min. I did not test that with 18 test2. Between the latest 3 kernals deep sleep drain is quite similar

Couple of questions:

How can one actually make use of the external backup and restore options in CWM5?

I have only found that it defaults to internal for both and I don't see an external sd option.

Is it possible to use a CWM app with this similar to the one Chainfire includes with his CF-Root kernel? I tried useing his CWM app and it doesn't properly perform backups and restores. I made a backup using it to test (twice) and it rebooted into CWM went through the procedure, rebooted, but the backup wasn't there... however the space was used, because the available space was smaller each time!

Not sure how I can recover that space, really, because the CWM recovery backups aren't in the folder on the sd card.

Day 1 usage from 100% charge, test 2 of build 18:

Initial thoughts, battery does drain faster compared to earlier versions and siyah whilst screen is on as usually I can get closer to 5 hours with around 13-14 hours, but will let this discharge to 0 and monitor performance tomorrow as I know what my normal day usage is like on working days so will get a good idea of how well it idles and such.

Seems to be spending more time in 1200mhz compared to earlier versions and other kernels and nothing I've used today should need that frequency for that time.

Fast and smooth as usual, no reboots, freezes and issues that other users are reporting.

ROM used Checkrom 3.1.1, and modem KI1. Kernel left on stock nothing touched.

Unusually high cpu usage by Android OS

Hi hardcore, i had used k16, then k17-test1 and k18-test2 kernels. Both k17 and k18 test kernels showed high battery consumption by "Android OS".

I lost only 4% over 8hours when the phone was left untouched overnight. With k17 and k18, i had lost more than 12% when left idle. Checking the usage monitor shows "Android OS" to be top cpu consumer.

Hope this helps...

That's true. There is something wrong with the CWM4 initramfs that causes factory reset to fail. The workaround now is to flash a stock kernel (or the old SpeedMod version without CWM) and do the factory reset using that kernel, then flash back SpeedMod.
