I think that hardcore just heard you ;-)

As Test10 seems to be very promising as being good for battery life on my phone, I will keep testing it, although something inside of my says: "Flash Test11 ... flash Test11 !!!"

No, I ... at least try to ... wait for some hours to have a representative impression of Test10's battery savings, before I flash the next SpeedMod kernel.

My current battery stats (after a "normal" day usage):

After 6h 14m 20s => 84% battery power.

Wifi on: 5h 57m 55s

Awake: 1h 9m 38s

Screen on: 25m 24s

(about 81% of deep sleep)

I will post my night results ... tomorrow.

[Galaxy S II Original Android Development] reand86:
someone know why after boot the battery drain is -2ma (only boot, without touching anything) and after a 3G connection (about 20 seconds, only turn on connection and turn off) the phone drains -47ma (screen off, all off) until next reboot?

it's a rom problem??or kernel related?

kernel: speedmod k2 v18test8 (drain also with siyah 2.1.1)

ROM: simple & clean v2.0

Hi hardcore, I follow your work in custom kernels since the i9000.

I'm testing the new kernels for the i9100 now. I don't know if this thing can be related to the kernel modifications, but the GPS performance was way better with the stock one, I think... :confused:

Updating from K2-16 to K2-18 Test 11.

Every day I plug in my phone to charge on USB while using the phone to listen to mp3s. With K2-18 T11, it says:

Info: Charging paused. Battery temperature too high or too low. (Ok).

This didnt happen with K2-16, and when you acknowledge it on K2-18 Test 11, it pops up about 50 seconds later, and will keep doing it. (and I had K2-16 on right before... which was running for about 7 hours, no apps open except music app, no apps syncing in the background, turned all of them off too.)

The battery is at 66 degrees, so its not that hot.

I used the phone the same way even up to K2-18 Test 6, but then decided to go back to K2-16 until a final K2-18 came out. I couldn't resist and tried the K2-18 Test 11, and that info msg keeps popping up every minute or so. Just letting you guys know....

--EDIT--

Weird thing, I go back to K2-16, and the temperature went down to 36 degrees. Flash back to 18-T11, the temperature goes to 66-67 degrees....

I knew it wasn't really 66 degrees, cause its not warm when I put my hand on it.
[Galaxy S II Original Android Development] dzontra11:
For me test 11...10 min of browsing lose 2%..nice.
[Galaxy S II Original Android Development] AMDPOWERFIST:
Yeah i have, that could also be the cause of there being more kernel wakelocks than the previous versions.

Here you go. I didnt get a chance to test 10, but i personally believe PREEMPT makes a different in battery life for me. There was a strange battery drain in test 9 i couldn't locate. Was losing about 2% per 30minute blocks... so was glad to get off that one and onto test 11.

Also just for Hardcore's info - there is a newer version of CWM v5.0.2.7 out, might be worth a look - i believe test11 currently has 5.0.2.3 - not sure what the differences are, but might have fixed some issues the older versions had....?

Benchmarks below:

Test results so far:

Testing is done in the same location each day a new kernel is released. Proceedure is as follows:

COPY NEW KERNEL ZIP TO SDCARD > BOOT TO RECOVERY > WIPE CACHE / DAVLIK > REBOOT RECOVERY > INSTALL NEW KERNEL ZIP > REBOOT RECOVERY > WIPE CACHE / DAVLIK > REBOOT

Battery Monitor Widget app info located here:

http://xdaforums.com/showpost.php?p=19416214&postcount=4418

K2-18

test3 had a 104mA drain

test5 has a 87mA drain

test6 has a 43mA drain

test7 has a 44mA drain

test8 has a 41mA drain

test9 has a 40mA drain

test11 has a 34 mA drain

Quadrant Scoring? :-

Conditions: Fully charged / reboot / record 3rd attempt

*note* - Quadrant scores are NOT a measure of real life speed, they are behind the scenes speed and scores should only be used as a guideline for serious issues rather than how the unit functions. E.g. a score difference of 1000 – 1500+ can show some serious faults or flaws in ROM / Kernel Combinations or hardware faults.

K2-18

test 3 had a 4307 score

test 5 had a 4723 score

These are however only tests done by my individual unit, every unit is different. Tests WILL vary from person to person / phone to phone.

________________

ill be away at a music festival for the next few days, so it will give me a bit of time to actually test out test11 kernel properly and give some proper feedback when i return. No doubt upon my return there will be another 4 or 5 revisions of the K2-18 or maybe a new K2-19 from which i will post some more results.

Cheers

Test 10 is not going into deep sleep again. Had to reboot to get deep sleep again.

woooow So far Test 11 perfect for me

Thanks Again bro :) u'r compairing very very usefull

i'm Totaly Agree With u, i believe too, that PREEMPT Mode is better than PREEMPT_VOLUNTARY for battery,it's not tu much but i Think PREEMPT mode does Guaranty ur Battery For Reasonable proceed (Something Like that ) :D My English isn't well (Actually it's Terrible :D), I hope ,you understand that what i mean About "Battery Reasonable proceed"
[Galaxy S II Original Android Development] planetf1:
Comparing idle with 10/11 I'd say it's too close to call.voluntary should reduce kernel latency so could be better for responsiveness buy can't point to any proven examples
[Galaxy S II Original Android Development] shahulvm:
4% drain for 8hrs should be fine with 3g and sync on. Not sure abt your overnight hours though
[Galaxy S II Original Android Development] shahulvm:
Am getting excellent battery life again in test11. Am sure preempt seems more battery friendly than preempt_voluntary. Though in theory voluntary should give better battery life.. This is called reality gap.....
[Galaxy S II Original Android Development] Hacre:
Er...

You're gonna start getting people complaining of random reboots.

Note: kernel-orig is the original EUR source we had from like, KD* 2.3.3. kernel-update2 is the "Rebuilt from Samsung 2.3.4 source code GT-I9100_CHN_CHN / I9100ZCKG4".

ninpo@titan samsung $ diff -crBN kernel-orig kernel-update2 > samsung-kernel-update2-test.patch
ninpo@titan samsung $ cat samsung-kernel-update2-test.patch | wc -l
0
ninpo@titan samsung $

It's exactly the same. You've downgraded. Always check your source, don't assume it's an upgrade because Samsung say it is (or peons on here for that matter).

EDIT: To make doubly sure:

ninpo@titan samsung $ md5sum GT-I9100_Kernel_Gingerbread-EUR.tar.gz

Hmm I was previously using i9100_opensource_update1 which is very different from this zckg4 version.

So you're saying that this zckg4 source is the same as the older GT-I9100_Opensource.zip kernel source? I've never used that so I can't compare it.
[Galaxy S II Original Android Development] Hacre:
Of course it's very different, update1 is an update to this source. It's exactly the same as GT-I9100_Opensource.zip. Which has a nice gift of random reboots.
[Galaxy S II Original Android Development] cr0wnest:
Just flashed the latest kernel (My first time using speedmod) and setcpu crashes at startup? It cant detect my phone's speeds properly at all so i'll have to do away with setcpu. Is this normal for this kernel?

Also i just realised that system panel is showing that the max clock speed is only 1000 MHz on this kernel. Is that normal as well?

Alright thanks. Just downloaded that package and checked.

[Galaxy S II Original Android Development] It_ler:
I am still running on SpeedMod K2-18-test10.

Over night (about 8h) I lost 8% with about 1h of time awake.

This was with synch/wifi/Talk and Skype on.

Compared to other SpeedMod kernels I have tested so far, this is a good value.

With Test5 I had about 5% battery loss over night under same conditions, but with other kernels, I always had more than 10%.

Here are my current battery stats after 1 day use and 1 night use (19h 7m 21s):

Battery power: 60%

Wifi on: 18h 51m 19s

Awake: 3h 18m 47s

Screen on: 1h 5m 8s

Deep sleep: 15h 49m 39s (82%)

Overall Test10 has got similar results to battery life than Test9 for me (my phone and my "normal" usage), although the drain over night was a little bit better.

Now going to flash Test11.
[Galaxy S II Original Android Development] FrenchSparda:
on my wife's sgs2, i had the same message few days ago with k2-16...it seems the phone was too cold ^^

Lost 2% overnight (8hours) with test11...no sync, 3g off on KitchenRom KI8
[Galaxy S II Original Android Development] It_ler:
And again ... I flashed SpeedMod K2-18-test11 and all my app folders were empty.

This time I have done: Recovery => wipe cache+Dalvik cache => reboot recovery => Flash new kernel zip file => reboot recovery => wipe cache+Dalvik cache again => reboot phone.

Hmm ... I will have to try something different next time - maybe without wiping cache at all?!

---------- Post added at 08:32 AM ---------- Previous post was at 08:17 AM ----------

I had one FC (social hub) on first boot. On second boot it was gone.

So, nothing dramatic.

Here are my first results of SpeedMod K2-18-test11 in benchmarks:

Quadrant Standard (3rd run):

4344 points (a little bit less than most other SpeedMod kernels so far)

CF-Bench (3rd run):

A little bit more native and java score (and as consequence a bit more overall score too) - compared to both, other SpeedMod and stock kernels.

NenaMark2:

slightly lower fps result than Test9 and Test10, which are still my highscorers.

All other benchmarks show similar results for all SpeedMod K2-18 kernels so far.

Over all I would say that Test11 is not as fast as Test10/Test9/Test2, but still faster than the latest stock kernels.
[Galaxy S II Original Android Development] Vahidmoby:
it's too Soon to Judge About Battery

But i think test 11 is the best kernel so far (For me)

According to Battery Widget,Cpu Spy,Better Battery Stats and Battery Percentage :D

Bsides,Realy Smooth and Snappy

I Don't Believe Benchmark's Scores (i believe These Scores Just Numbers)

VIVA PREEMPT Mode :D

@Hardcore. I am a serious SIP user on both my SGS1 and SGS2 and always had a problem with the process phone fc on answering. Basically from the release of 2.3.4 but after installing test 8, the fc on the SGS2 were gone. SIP working basically perfect.

I have installed test 11 and the fc are back. Reverted back to test 8 and the fc is gone.

This is the first time ever with all the roms and kernels that I have tested that I could pinpoint the problem to maybe something in the kernel and that I found a combination that works.

Is it possible to shed some light on what could be different in test 8 that is not in the other kernels that could have contribute to the fact that test 8 is working and not test 11

I would prefer to use test 11 as the combination between speed and battery life is excellent.
[Galaxy S II Original Android Development] aqualeris:
#5000 post awesome!

I'm on 18 test 1 honestly and I am very satisfied with the battery so I don't see the need to change anytime soon unless there is a release with really good rave reviews. So far everyone seems to have different opinions on the recent releases so Just gonna stick with test 1 and be happy.

Great job hardcore. :p

Oh ... it must be "voodoo magic".

Someone is remotely controlling all of your phones ;)

Ok, although all of you have already tried it - for sure, but ...

... does it help to clear app data via Settings menu => Applications => Manage applications => ... (search for your voodoo app) => Clear data?

Then wipe cache partition (and Dalvik cache too) in recovery mode.

As I am sure that you have already tried this before and nothing could help, I feel sorry and recommend to use another kernel.

Maybe it is in deed a kernel issue ... as I do not use the voodoo app, I really don't know.

With test 11, I've lost all the smoothness and the reactivity that I had with test 8 wich is, until then, the best for me. I'm on Batista rom and with test 8, my phone react at the speed of light ! My battery life is about 35~40 hours, with full screen light, seven desks (launcher pro) and a lot of widget. Test 1 was also very good. I had Jeffrey Speedfrey kernel before, but this one makes my phone fast and smooth ;)
