Whats the main benefit of using the TS sensitivity to 0, does it make it more jittery ?
[Galaxy S II Original Android Development] hardcore:
Hmm. Setting the touchscreen sensitivity to 0 makes the touch very jittery.

I'm going to put up a K1-T15 with it set to 10.
[Galaxy S II Original Android Development] EarlZ:
I found that 5 is the best, Maybe you could look into the touch threshold it self, the S2 feels more of a resistive screen at times requiring greater finger contact for it to register movement, I miss the threshold level of the Galaxy S1 when it was still with andriod 2.1 maybe you could look it up ?

Got 3% drain overnight with 18test1.

7 hours deep sleep

1 hours 200MHz

I Did not touch the phone overnight.
[Galaxy S II Original Android Development] eranyanay:
I left the phone with K18-test1 overnight plugged to power,

And I noticed with cpuspy that instead of sitting at 200MHz its at 500MHz.

Could it be its causing charging to be slower?

And for me Android os has very high % too.
[Galaxy S II Original Android Development] lrcquest:
The higher Android usage % can be due to the AOS bug as mentioned in the earlier posts.

As for the 500 Mhz, can u check which all processes are consuming the resources?? On K-17 test1 i did get deep sleep when on charging, however, was on 200 Mhz when i was on k-16. Will check out the same on the 2nd charging cycle & post!

Also, pls do the battery calibration prior to using in full swing as this helps to set things right.

- post installing new kernel, full charge with phone switched off.

- when fully charged, pull out the battery, wait for 2 minutes, reinsert the battery.

- restart the phone & use.

Battery calibrated!!

Is there a way to lock the phone to deep sleep or 200 Mhz when the music player is on ? Can't the phone deep sleep when music player is on and screen is turned off? Coz I noticed wakelocks while it was on and it drains battery like crazy. I lose almost 4% under 30 mins .

thats why i wonted to check if any one uses it

HC: can we use his without any problems ?
[Galaxy S II Original Android Development] lrcquest:
Trust so. But since we are already on the Speedmod & knowing that Hardcore has a no-go policy on the unstable changes front, it wouldn't be required. The update chain is from the same developer & are incremental in nature.

I think this will be of use for those switching kernels from different sources.

The S2 battery does NOT need to be calibrated. Plenty of info on xda about that. Thanks to Entropy512
[Galaxy S II Original Android Development] It_ler:
Just for those who are interested in:

I recognized that SpeedMod K2-18 test3 has a little bit lower results in some benchmarks, such as:

a) Quadrant Standard: about 4100 points against test2 with about 4600 points, and

b) NenaMark2 (OpenGL): About 38,8 points against test2 with about 48 points.

(I repeated the tests several times.)

Other benchmarks show nearly the same results, or at least no significant difference between test2 and test3.

Anyway, for me the battery life is more important. That's what I am curious about.
[Galaxy S II Original Android Development] :
I did three test in a row with test3 and got the better score of 4750+ with quadrant.

Using checkrom 3 kj3 based.

My phone is simply flying with normal every day usage :))

Hey KennyLegend

There is actually a lot of info regarding gs2 battery not to be calibrated. However i had a strange phenomenon today. Today was my first day on k2-18test1. The battery was working superbly since morning. Generally my battery gets drained within 8 hours as my daily calls are about 2 to 2.5 hours and i think that takes a lot of battery. But today in 7 hrs and 20 minutes my baytery consuned was only 52 percent and the total talk time till then was 2 hrs and 11 mins. I was ecstatic. But then suddenly my gs2 started behaving strangely and the voice in the calls stopped getting thru. So i restarted the phone and the battery which was at 40 % dropped down to 12% after restarting the phone. The battery usage is still showing about 40% balance as per the graph. Then i checked cpuspy. 1200mhz and 1000mhz which was at one % each since morning had jumped to 7% for 1200 mhz and 4% for 1000mhz. Any ideas why this happened and how to prevent this. All my happiness over the greAt battery life was finished. Pls help somebody.

Regards

Edit: i am also posting two screenshots of the battery usage.

Bascially, I was using the phone, then switch off, then immediately I want to turn phone on again....but the phone doesn't respond to both power and home buttons. Basically it cannot wake up....the phone remained in this SOD stage until about 10 - 20s before it comes back to life.

Bit offtopic

When I am flashing this kernel using Hc-ktools app available on market. I m not getting yellow triangle warning. In about phone I m getting correct kernel info as well. phone working absolutely fine.
[Galaxy S II Original Android Development] It_ler:
Alternatively you can use CWM Manager app from one of Chainfire's CF-Root kernels to flash just the zImage as new kernel, and you will also get the SpeedMod kernel flashed without a yellow triangle (and without incrementing the binary counter).

P.S.:

If you had once flashed a CF-Root kernel, the included CWM Manger app will stay installed, even if you are running another kernel afterwards.

There are many restrictions in CWM Manager app as it is designed to work with a corresponding CF-Root kernel, but the feature to flash a kernel (zImage file) from the internal sd card will still work fine.

Using k18 test 2 since its been available. Not noticing any excessive battery drain, strange cpu behaviour or any strange behaviour at all for that matter. What were the tweaks to the ondemand governor just out of interest and what were they implemented to do? Cheers for sharing it all with us hardcore!
[Galaxy S II Original Android Development] amitoberoi:
Another strange thing. The battery is not getting reduced even though in the last hour and half i have clocked a talk time of more than half an hour but the battery is still at 12%. Does this mean that tha juice in the battery is available but it is not being displayed correctly.

Guys can anybody pls explain whats happening.
[Galaxy S II Original Android Development] Mustoura:
I had this happen to me only once i do same voice usage as yourself . It never came back thank god and i never found out what caused it.

18 test 2 does drain battery a little bit more than 18-1 and it makes scenes as it hits 1200 more often ,which means it needs more juice so i am stuck i find 18.1 lasts a little bit more and 18.2 more snappier grrr time to test 3

Hardcore great work

Hi,

I try my question, do you plan to propose an underclocked kernel (limited to 1Ghz for example).

I think it is not incompatible with speedmod spirit ;) => it is stable and battery efficient :confused:

In all cases, thank's for thie very good kernel.
[Galaxy S II Original Android Development] ithehappy:
I really don't understand why some people purchased GSII knowing that it had a 1.2 GHz CPU! Didn't you guys find a device with 1 GHz CPU on first place? or even with that you'd have needed 800 MHz?

Maybee because I did not bought SGS II for the CPU, but for the screen/Size/weight :p

And I think that 1ghz is enough for my usage ! (at the beginning SGS was announced @1Ghz)

Which point ? Overclocking ? Undervolting ?

I don't see point on underclocking... As I explained, I don't think it is a problem for stability or battery life...

If 1ghz speedmod can be as fast as stock kernel@1,2Ghz, it can be a good deal !

[Galaxy S II Original Android Development] BrandoHD:
You should also check out better battery stats, that app will tell you what app/apps are causing the wakelocks, without it, flashing different kernels to eliminate wake locks is a guessing game

If you consider the improvements modest and don't like the color tuning, I am confused as to why you use the kernel in the first place :confused:

Newer is not always better, KI3 has always performed better than KI4 for me, radio performance is dependent mostly on location and not date...

[Galaxy S II Original Android Development] ewokuk:
why not? because its pointless. the cpu frequency is adjusted according to what it needs right? so if something NEEDS 1200 to at its best, itll use it......and if it doesnt then it wont. so capping it at 1ghz will do absolutely nothing for battery life unless you constantly use things that push the speed to 1.2.

i checked today, after 24 hours uptime, playing music, web browsing and a fair bit if angry birds, it spent a grand total of 2 minutes at 1200, 8 mins at 1ghz, 26 mins at 800 and the rest at 500 or below.......capping it to 1ghz would save me nothing what so ever in battery life. even capping it at 500 would be a very minimal impact and not worth it. obviously if you constantly run things that use 1.2ghz it may help restricting it to 1ghz but i seriously doubt itll make much difference, the whole point is the thing is designed to use the speed it needs to use in the first place.

where you might get something worthwhile is undervolting it depending on how good your cpu is and how low you can go on it, but since hardcore doesnt want to add this you may as well forget about doing anything with the cpu, you wont save much, if anything.
[Galaxy S II Original Android Development] SupraN0va:
For Your usage, not for my. For me 1200 have same usage time as 800. However I calculated, I will save battery life.
