Many thanks hardcore! U're amazingly hard working and uncompromising :P

I've tried K1-5, K2-1, K2-2, and K2-3, and it seems to me that K1-5 is by far the most battery-efficient (giving rise to the longest battery use) (but have to point out that all of them are very battery efficient compared with stock, CF, and franco kernels). Do u think it's possible?

I'm using KingDroid ROM v5.4 (ie. LB1). Could u tell us if K2-X is more compatible with LC1, or is it not relevant?

Thx :)

Power cycled the kernel for three times now, but unfortunately battery life is horrible on my device. Apps take most life. It drains battery in stand by mode. I have to move on and try another one. Thanks for sharing though.

Concrete figures to compare battery consumption btwn K1-5 & K2-3

Now, I have concrete figures to show that the battery consumption rate of K2-3 is indeed a lot more than that of K1-5:

With K1-5:

First, I reset my battery stat when my 2,500 mA battery is fully charged.

When the battery level is 74% (Fig. 1), the battery stats are as followed ---

Deep Sleep: 15h 22m 55s, 90%

200Mhz: 1h 13m 21s, 7%

etc.

To calculate the rate of consumption (in mA/sec), C(DS), when device is in Deep Sleep:

Amount of battery used = 2,500 mA * (100 - 74)% * 90% = 585 mA

= C(DS)*(15*60 *60 + 22*60 +55)sec

Thus, C(DS) = 0.0106 mA/sec ---------------------------------------(1a)

Similarly, C(200Mhz) = 0.0103 mA/sec --------------------------------(2a)

When battery level is at 47% (Fig. 2):

Deep Sleep: 19h 29m 27s, 81%

200Mhz : 3h 15m 1s, 13%

etc.

Thus, C(DS) = 0.0153 mA/sec ----------------------------------------(1b)

C(200Mhz) = 0.0147 mA/sec -----------------------------------(2b)

Hence, with K1-5, the rate of battery consumption is around 0.015 mA/sec

With K2-3:

Refer to Fig. 3

C"(DS) = 0.0354 mA/sec ---------------------------------------------(1"a)

C"(200Mhz) = 0.0332 mA/sec -----------------------------------------(2"a)

Hence, with K2-3, the rate of battery consumption is around 0.034 mA/sec

It shows that the rate of battery consumption of my SGN (KingDroid v5.4, LB1) is about 126% more when it is installed with SpeedMod K2-3 than when it is installed with K1-5 ! ! !

Isn't it surprising??! I'm truly surprised, but the figures are solid.

With K1-5, my SGN can survive a little bit more than 2 days of normal use (online at leisure, offline reading during commuting); with K2-3, a tiny tiny bit more than 1 day (Figs. 4 & 5)

is the kernel compatible with DarkyRom Note v3.3 ICED?
[Galaxy Note GT-N7000 Android Development] betoNL:
Hey...I missed the K2-4;)

Anyhow, choosing zips from recovery is still mixed up..internal go to external and otherwise...

But it have been told tons of times before....

I guess we gonna have to learn how to live with this minor mistake :D

...
[Galaxy Note GT-N7000 Android Development] hardcore:
Thanks for your efforts, but I'd say that in deep sleep mode, the kernel doesn't make too much of a difference. With a difference on that level, it is probably due to the GSM/3G radio or WiFi that is making a much bigger difference. Even a slight difference in 3G signal can make a huge difference in battery usage.

My gut feel is that the battery life is similar. I'd say, use it for a week or several days to average out your usage pattern.
[Galaxy Note GT-N7000 Android Development] macky1730:
same here sd card internal and external are interchanged in recovery mode
[Galaxy Note GT-N7000 Android Development] kwokshsee:
Thx buddy :)

What u say of coz is possible. But there are two clues that suggest otherwise.

First, the rates at Deep Sleep with the two versions are significantly different.

Second, the rate of battery depletion of K2-3 shown in Fig 5 is much nearer to a straight line than that of K1-5 (Fig 4), which means that with K2-3 the battery depletion is more a constant phenomenon, rather than a on-demand/task-related one (the clear steps-like depletion chart of K1-5 is more typical of a on-demand/task-related depletion with each step).

So, I still tend to believe that sth with K2-X constantly depletes the battery at a higher rate.

However, I am still happy to test K2-5 more thoroughly as u suggested :)

Cheers!

Just flashed the latest K2-5 through CWM. Buttery smooth! Very tangible!

Was looking for a kernel along the same philosophy - no undervolting/overclocking and with performance optimisations.

Now I am hoping the battery lasts long too - afterall, that was the primary reason I switched to Note! Otherwise will downgrade to the K1-5 kernel that some people have verified above as having good battery life!

Thanks!
[Galaxy Note GT-N7000 Android Development] thoriig:
Very strange. I made some benches with speedmod and francos. Francos got 7800 in cf bench. Speedmod 7300. But speedmod got 1390 sunspider benchmark and 98000 rightmark. Around 6k more than francos. After a detail look francos seems to be a bit faster with io related things.

Batterylife seems almost the same: around 25-30% a day with umts.wlan.bt and pushmail/rss news/facebook and alot of music over bt. Full usage :)

Very good. Unreachable with stock kernel.

Now the userfeeling: speedmod feels more responsive, special wake up from deep sleep. Hard to explain. Note seems to react faster.

Tested francos beta kernel and speedmod k2-5. both tests with full wipe and jbroid cleaning.

I will stay with speedmod.

Didnt found any gaming related differences with mc3.deathspace and shadowgun.
[Galaxy Note GT-N7000 Android Development] jermitano:
why the need for a full wipe??? just clearing cache and wiping dalvik does the trick...well jbroid (assuming some fixes have been made)...

[Galaxy Note GT-N7000 Android Development] travis82:
why put the gpu clock back down? Also I looked all over the op post and the webpage you have. Where are your kernel sources? I can't find them.
[Galaxy Note GT-N7000 Android Development] hardcore:
You didn't look hard enough. Sources are in the 2nd post, right below the OP.

I put the GPU base clock back to stock because I decided to try a more aggressive GPU DVFS policy, which should compensate for the performance while giving better battery life.
[Galaxy Note GT-N7000 Android Development] betoNL:
With Tegrak Overclock Ultimate app (which is compatible with Speedmod) you can adjust the GPU as well....

I am having some problems with deep sleep with K2-6. My guess is that it's caused by the PREEMPT RCU, so I'm going to revert that and test again.
[Galaxy Note GT-N7000 Android Development] FiremakerP:
Did not have any trouble with deep sleep. The phone drains almost no battery when in stand by mode.

In addition to that the 160mhz stock speed is not noticeable! When playing games the gpu will go up to 267mhz so no reason for 200mhz.

Hmm.. Any chance to disable the Colour tuning.. I'm too used to the colours on stock Kernels, others just makes things look washed out to me.

Had no problem with deep sleep. As in previous versions overnight drop was 2% with auto sync on.

Hardcore, all the versions are battery efficient but I managed to get 4 hours of screen on time with v 1-5 with heavy usage (heavy - continues gaming and internet). Can't say v1-5 is better than newer versions as I used it only for a day.
[Galaxy Note GT-N7000 Android Development] kwokshsee:
K2-5 preliminary result

With K2-5, my battery consumption is 2% for an overnight sleep with near-zero activity (airplane mode, alarm on).

C.f. with K1-5: 0% with zero activity (airplane mode, no alarm set).

(Will have more accurate figures in due course :) )

what is that about CWM version?

Hi guys,

I am reading quite often about the wrong CWM version. What do you mean, what´s the problem about, can you please explain? Will it cause a problem for me when using that Kernel?

BTW: I am using the latest version of that Kernel and I think it is very good!
[Galaxy Note GT-N7000 Android Development] kwokshsee:
The fuss about CWM is, in my opinion, unwarranted. It is about the fact that Speedmod Kernel is not totally compatible with CWM Manager, which is an app that enables you to, among other things, initiate ROM backup and restore after ur phone is fully booted up. Becoz of the imperfect compatibility, the ROM backup and restore functions of CWM Manager are not supported, so u cannot use CWM Manager to backup or restore ur ROM when u're fully booted up.

HOWEVER!!! U still can backup and restore ur ROM thru CWM Recovery thru the Recovery Mode!!! That is to say, to backup and restore ur ROM with Speedmod in-situ, all u have to do is to reboot in the Recovery Mode, then u can do so from the CWM Recovery console there.

So, the fuss has all to do with, I'd say, an obsession ppl have with CWM Manager, which just automates the process of rebooting into recovery and choosing backup/restore for you after u're fully booted up. You can really do without it as long as CWM Recovery is there, which very much is with Speedmod Kernel.

I hope this helps :P (click "thanks" if it does :) )

Hi Hardcore

I am using rooted ddkb2 and want to flash your kernel. I am currently running stock kernel. I saw your instructions on flagging using odin but it will increase the counter which will void the warranty. Can i use mobile odin or chain fire tool to flash the kernel?
[Galaxy Note GT-N7000 Android Development] M3TALLICA:
Yes, you can use mobile odin or CWM application. It does not change custom binary counter.

Good luck.

---------- Post added at 11:18 PM ---------- Previous post was at 11:16 PM ----------

If you do not have clockwork recovery, extract 2-7 zip, and flash the zimage using CWM application. If you have clockwork recovery flash the zip directly.
[Galaxy Note GT-N7000 Android Development] jaskiratsingh:
I don't have a cwm application. Can you share it?
[Galaxy Note GT-N7000 Android Development] M3TALLICA:
You can use mobile odin as well. In mobile odin kernel>browse to 2-7 zimage>select flash firmware

Or

Download HC-kTool from the market and flash the zimage.
[Galaxy Note GT-N7000 Android Development] M3TALLICA:
Here you go.
[Galaxy Note GT-N7000 Android Development] betoNL:
I dont think the fuss is only about the lack of full compability with CF's CWM Manager app.

It is also about errors present within the built-in cwm recovery such as:

- SD cards cannot be mounted from recovery

- installing zip from recovery is mixed up when choosing them (internal and external SD are mixed up) what can be confusing and annoying for those trying speedmod for the first time.

- maybe even more errors

I think that a optimized kernel of the Caliber of Speedmod, should have a better built-in CWM...

Why not make what's good, even better?

It's just a shot in the dark cause I am no developer, but is it possible to use CF's version of CWM5 which is fully functional?

Sometimes it's handy to mount sd card from recovery, for instance...
