no i guess i really don't abuse data too much...just had a kid, post about it from my phone with wifi (on the whole time btw, sleep when screen off policy) about 3-4 times a day and post a few pics of him....

i honestly don't use that much data....i would consider myself an average/moderate user, no where near a heavy user....

right now i'm at 23 hours and 54% - i guess thats an average of about 2% an hour...

again, lookin at the graph from when i was using the GPS/Navi it is a pretty steep drop of juice....
[Galaxy S II Original Android Development] glenncain:
2% per hour with your navi and calls accounted seems quite sick.

but i could say you did not use 3g at all or switch it on to standby, all on just wifi eh?

guess that explains abit of difference~

but its all good news~
[Galaxy S II Original Android Development] bunnybash:
Everytime I flash your kernal my phone no longer finds a phone signal, as if no IMEA exists, I flash back to another kernal and it's all good again... very very strange and annoying!!

But my phone uses WAY less battery on your kernal too... sigh...

EDIT: If I go into download mode after flashing your kernal and then reflash my modem, then my phone can see my sim card again.
[Galaxy S II Original Android Development] joezy07:
hi !

is this kernel support boot animation ?

Thanks !
[Galaxy S II Original Android Development] Thedonk13:
I have my data on all times...I'm even roaming because my company doesn't have coverage here....small Alaska company

battery life comparison

Has somebody tested both speedmod kernel and void.charlie...

Any comments on battery life...
[Galaxy S II Original Android Development] malavan:
thanks that was easy
[Galaxy S II Original Android Development] Seifer1975:
I just switched from speedmod. Charlie gives alot better deep sleep for me.
[Galaxy S II Original Android Development] shahulvm:
How about the battery life when the phone is being used?
[Galaxy S II Original Android Development] Urokinase:
I flashed the kernel yesterday. In the last 13 hours (overnight) it uses 15% of battery with WiFi on and sync on.

MfG Uro
[Galaxy S II Original Android Development] shahulvm:
I feel this is almost on-par with speedmod kernel or little more battery draining than speedmod kernel...for now I shall stick with that..anyways thanks..
[Galaxy S II Original Android Development] Talvathir:
I like the idea of this kernel, but the drain when using the phone is just too high, I'm at 71% after 13h with just under 1h screen-on, and during that hour I haven't done anything besides use tapatalk with the black background. Yes, deepsleep is good but unfortunately not good enough when compared to Siyah so I'm back to RC2 until a new version of void is released.

thnx for your hard work thus far knzo :)
[Galaxy S II Original Android Development] :
I have to quote you although my results are a bit better :)

What about a shorter latch for the lion mate? We would lose a little bit of performance maybe, but since it's so high I'd be glad to exchange more than a little to get more battery life, which has always been the unique little flaw of this phone :)

I flashed charlie just now through odin..but the phone got stuck at yellow triangle and didnt boot up...waited for 10 mins..and i even was unable to boot into recoverry and to flash another kernel...plz see 2 the problem..

p.s i m on criskelo kj3 rom and was previously using siyah 2.2 rc2...
[Galaxy S II Original Android Development] lilbrat:
Well this looks promising as I'm an average but I like the ideas that have been posted here so this afternoon I'll load your charlie version and give it a try as I'm curious about the battery life as I average about 2 days without needing a charge as I'm currently running Siyah v2.1 rc3 so I wish to see if there is a big difference as I don't use half the things included in it like bln and oc and such..included my benchmarks so I'll have a reference.. sorry for the long post..

[Galaxy S II Original Android Development] SupraN0va:
Charlie is pretty good. Standby drain until now is about 4,5/4h for 1%. Performance is also good as always with an dual core.

Can't wait for UC feature.

Worksreally done fine for me.

Thx

Testing the V.charlie WITHIN Check Rom 3.1.1, battery drain upon heavy usage (5min>1%), excellent performance, fixed deep sleep problem, plus a strange fact, i'cant factory reset trough phones dialer (*2767*3855#) ! I believe this kernel have a bright future !
[Galaxy S II Original Android Development] ephraim:
This kernel is great no doubt but one thing i noticed is it spends alot more time on higher frequencies than speed mod.. other than that this is great.. will wait for delta update..
[Galaxy S II Original Android Development] SupraN0va:
Sry but I cannot agree. See my stats.
[Galaxy S II Original Android Development] ephraim:
Maybe for your usage it stays down.. will test again..
[Galaxy S II Original Android Development] devilkin:
500 is definitely the minimum with the screen on. Voltage control from the market also shows this.

Interesting, will download and report back:)
[Galaxy S II Original Android Development] downesey:
The kernels deeps sleep mode is fantastic and saved my 20% battery for over 12 hours. however when in use it does deplete on par with other kernels, but id expect that. I will play around with the best frequencies to run with and see what i can get

thanks
[Galaxy S II Original Android Development] paulyluca:
After the right balance between speed and battery saving is found, this will be the most awesome kernel.

When will be next uptade ready? Cant wait to test it... :)
[Galaxy S II Original Android Development] Skimi:
I have installed on top of Cognition 777 r2 and so far so good, Thanks.

Força aí!
[Galaxy S II Original Android Development] haieb:
Is the siyah kernel using some hacks to achieve this result? Oo

the deepsleep is very good on this kernel. After 21h i have 50%. The problem is the drain when using the phone.

BTW: first cycle and OS-bug...
[Galaxy S II Original Android Development] hacksome:
I could get some more juice out during the 'usage period' by :-

1) Disabling auto brightness

2) Disabling Auto adjust screen power

3) Keeping the brightness to the lowest readable level

4) Using Screen-Filter app to reduce the brightness further.

:D I still could read inside the house.
[Galaxy S II Original Android Development] gokhanmoral:
this question is for me I guess. no, there is no hacks for anything other than quadrant which is already old and gives fluctuated results.

those antutu scores are real and in fact I always get >6000 with stock frequencies for a long time.

The only thing missing from this amazing kernel is the ability to alter the charging voltage. So It's back to Siyah for me...

Siyah later... ;-)
[Galaxy S II Original Android Development] mustafahusain:
Great Kernel. Small Issue

Superb kernel. Smooth and good battery. However I have noticed a weird issue since I installed this kernel. I get a crackling noise while playing any sound on my phone (including music, video, notifications and ring tone)> Anyone else noticed this?
[Galaxy S II Original Android Development] sebarkh:
+1 about the sound quality...
[Galaxy S II Original Android Development] mustafahusain:
Fixed

I did 2 things -

1) Ran the Kernel Cleaning Script (Link on OP) and reinstalled this kernel again

2) Disabled CM7 DSP Manager

not sure which one fixed it.

Alls good!
[Galaxy S II Original Android Development] qureyoon:
Here's some test results. This kernel is indeed blazing fast. Performance is very good. This cause a bit of battery drain.

A lot of manga reading (screen on always), 3g all the time, poll email every hour from 5pm to 8am, regular use of xda apps as well.

I like the speed. Hopefully this could have more potential on battery as well :-)

Can't wait for stable release!
[Galaxy S II Original Android Development] knzo:
void.delta released, read the changelog for kernel/initramfs and check the new section of void interface settings - many important information there.

Still light as a feather of course.

In comparison:

void: 4.7 MB

Speedmod: 6.4 MB

Lulz: 6.4 MB

Siyah: 7.4 MB.

Even with the discount of the initramfs size, you can see how crap-free this kernel is.

As for these benchmark talks, remember one thing I already wrote in the past: there are some void features such as the granularity values of CFS that even though they increase smoothness, they will decrease benchmarks. I find the obtained results very good taking this into account. If I just wanted to pop, I would've gone for BFS 413, different granularity, different sysctl values and so on.
[Galaxy S II Original Android Development] snailmale:
Thanks, will test this right away!

Any special reason why you chose 1000mhz as your cap instead of the standard 1200? (besides saving battery of course)
[Galaxy S II Original Android Development] knzo:
It's nearly as smooth and saves more battery.
[Galaxy S II Original Android Development] bervin:
Is there any wat that i can undervolt even more? can i put in scripts in init/d to UV it even further?
[Galaxy S II Original Android Development] antt00:
I think you can. Setcpu also working well with delta. So far its very very smooth. :D
[Galaxy S II Original Android Development] spirt:
in void settings interface i can see twice NFS option (numbers 3 and 5).

as i understood under 3 it might be CIFS option?
[Galaxy S II Original Android Development] snailmale:
Each time I reach the 3D part of Quadrant (the globe part), my screen locks up on me and the phone stops responding. Had to force reboot once, and it's happening on the 2nd time too. I ran the ROM cleaning script before flashing this but still ran into problems. Will try running the script again and re-flashing. on Delta, btw.

Ran script again, reflashed, still having the same problem. Anyone else having the issue? The kernel is blazing fast though.

EDIT: Removed the stock UV, problem fixed. I guess my CPU/GPU is more sensitive than normal
[Galaxy S II Original Android Development] shahulvm:
Did you undervolt, if yes then one of the undervolted frequencies isnt enough and the cpu is freezing
[Galaxy S II Original Android Development] snailmale:
No undervolt applied, other than what was already standard. Shall try changing back to stock voltage with the user interface to test.
[Galaxy S II Original Android Development] -ph-:
1 SOD here!

When I lock the phone and it get's into deep sleep he doesn't wake up again...
[Galaxy S II Original Android Development] spirt:
strange, but default freq range for me is 100 Mhz - 1200 Mhz by default.

init.d is empty, no UV/OC, no SetCPU or other apps.
[Galaxy S II Original Android Development] snailmale:
I have deleted setcpu (since i moved to speedmod), but CPU spy does tell me mine is going to 1200 as well. I suppose knzo left it at stock after all.

I'm on stock XXKI4, btw.
[Galaxy S II Original Android Development] shahulvm:
I think knzo undervolted the kernel by 50mv as he said ref fenomeno...

So I suggest to increase +50mv and it should be fine for you..
[Galaxy S II Original Android Development] :
Great can't wait to test it!!! :))

Time to re enable setcpu to under - over clock then? :)

Sent from my SGS2 - Checkrom Revo 3.1.1 | Speedmod k18 | Vertumus ICS Theme |
[Galaxy S II Original Android Development] knzo:
Correct, it will be fixed in the next version.

Yeah, it was stock UV.

No need, he just needs to disable the auto UV on void settings interface. It's a more elegant solution.

My beta-tester who had SOD before didn't report any on this version.

It's probably a one time thing or something in conflict with the kernel.

I must have forgotten to change the value, great.

I will correct it in the next version; meanwhile you can always force 100 - 1000 Mhz with an app though.
[Galaxy S II Original Android Development] haieb:
i got SOD, installed voltage control and saw that 500mhz had 850mv. i know that my cpu doesn´t support this value, so i set 900mv and its working now ;)

edit: another sod,i think i have to disable UV^^
[Galaxy S II Original Android Development] joezy07:
hi, just tested this kernel today when it's still void.charlie.

very good at preserving battery, but when I play a game (Baseball Superstars II) I found it a bit laggy.

I never found this problem with the previous kernel (speedmod).

is it fixed with void.delta ?

Thanks ! :)
[Galaxy S II Original Android Development] gasmias:
Battery life isnt the strongest point of this kernel..when phone is awake (screen on, etc internet),kernel uses more power than others kernels..

Display is taking the lion's share of battery life

All, I feel display is taking lion-share of battery life when the phone is being used. I suggest to use superdim or chainfire-3d to lower the brightness...ie to lower it beyond the OS defaults to a level which you think is fine for you...

THis could give slightly better battery life

---------- Post added at 11:40 PM ---------- Previous post was at 11:33 PM ----------

using void, i getting the following options only

# void

~ void settings interface ~

Pick your option:

(check the FAQ if you have doubts)

1. Disable CPU/GPU UV

2. Disable fsync()

3. Download modules

Enter your choice: ^C

Can you please add an option to exist the menu. Thanks
[Galaxy S II Original Android Development] :
Smoothness is incredible indeed as well as speed, but delta lowered my max quadrant at about 5000 5100 Charlie had peaks at 5700. Using default settings @1200 with uv enabled.

Did a go @1600 out of curiosity but got a sudden reboot. Nevermind :)

We'll see battery life, but it looks to me that it still eats power pretty fast while using the phone...I don't want to uc to 1000, since I paid for my 1200 ;)

[Galaxy S II Original Android Development] Seifer1975:
Can anyone enlighten me?

What is the benefit of having the 100 cpu step when the voltage is the same as 200? So theoretically it will take twice as long to complete a task at 100 than 200, and hence twice the battery consumption as well, since voltage is same. isn't that worse for battery life?
[Galaxy S II Original Android Development] grisha1:
Frequenzy * voltage(2) makes power consumption. So theoretically this means half.
[Galaxy S II Original Android Development] Seifer1975:
But assuming that time taken to complete the same task is twice as long at 100 than 200, isn't the net result then the same?
[Galaxy S II Original Android Development] goodsmile:
Wooooow flashed new delta no problem whats so ever. Quadrant on kernel base stock sti getting 5500+ and with oc to 1600mhz i'm getting 7500++
[Galaxy S II Original Android Development] grisha1:
Time is not part of the equation :-)

SGS2 via Tapatalk
[Galaxy S II Original Android Development] snailmale:
of course it is. frequency = 1/t

I'm no expert but if frequency * voltage^2 = power consumption (e.g. in Watts)

then frequency * time * voltage^2 = power consumed (e.g. in Watt hours)

Edit: but of course, voltage^2 is not equal to power. its more like its a relationship. more of P = V * I, where the main variable we are changing would be resistance R. Since V = I * R, then P = V^2/R or P = I^2 * R.

So,

e = P * t = V^2/R

Where e = energy, P = power (watts), t = time, f = frequency, V = voltage, I = current (amperes), R = resistance (ohms)

Sorry, can't resist recalling my secondary school physics! my favourite subject at one point!

[Galaxy S II Original Android Development] Bushido76:
Hey knzo,

thanks for integrating the OC/UV option in your kernel. I experience some problems with void.delta which did not occur in void.charlie.

Situation:

- just void delta on a clean rom

- no other tweaks and scripts

- no UV or OC

- auto UV is disabled

- just using default values

Problem:

- I cannot complete a full quadrant run (I don't use for benchmarking but for stressing the cpu).

- I get artefacts and freezes during the planet scenario.

Unsuccesful tests:

- enabling and disabling the auto UV-feature (with reboot ;-) )

- reflashing the kernel

- cleaning cache and dalvik cache

As mentioned before I never experienced such a problem with charly. It seems to come with the new OC/UV code - even when not used (disabled). Maybe the GPU undervolting algorithm is responsible for.

Thx in advance,

Bushido
[Galaxy S II Original Android Development] knzo:
Yes, I know of the issues.

I'm already beta-testing echo which should be more stable:

- Ext4 journalism removal can now be reverted on void settings interface

- No more GPU clock/vdd support

- Min frequency raised to 200 Mhz (can be reduced to those who can handle it)

- Auto UV disabled by default (can be enabled by those who can handle it)

- Added AOSP support (still experimental)

- filesync() and ext4 no-journalism disabled by default

- Some wifi patches to see if it consumes less power

- Some void settings interface fixes and corrected typos

- Updater-script will now clean cache, dalvik-cache, init.d, modules and previous void traces to minimize problems

I think you can expect it today.

If there are still problems, then I will remove altogether the OC support.
[Galaxy S II Original Android Development] ferreinf:
Use SetCpu 4 example, and change your UV settings, not all CPU are the same, mine is working fine, add 25mV on each freq. and see what happens ;)

I'm currently on void.charlie and it works brilliantly. My battery life is certainly improved, although not long to judge exactly the improvement I'd say it is about one third greater battery life.

I'm looking forward to trying void.echo but please keep the kernel to its original aims of being simple, lean and smooth. It's exactly the reason I chose this kernel over the others in the forum, which require a PHd in computer science and a choice of tens kernel varieties.

Overall fantastic, keep up the excellent work!

I wonder if it's a bug, i have this app homeMyhome, it's suppose to open another app, which i assigned to when i double click home button.. there were a few times when i press the home key once, system responded so fast, it actually activated homeMyHome..

another possible bug i noticed was, i had my Tiny Tower running in the background, then i return to home screen and locked my phone.. when i unlocked my phone, other than keying in the pattern to unlock my phone, i did not press any other button, but somehow when i return to the game, the game menu kept flashing, though it stopped when i pressed the menu button again.. it never happen in the past when i haven't yet flash this kernel..
