As i said.. on idle @ min gpu 400Mhz .. the GPU freq is half due to APE 50% = 400 / 2 = 200Mhz ..

We have 200Mhz of GPU freq when CPU is min = 400Mhz, and also actually CPU is 400Mhz .. when CPU is 600Mhz or higher then GPU is min. 400Mhz or even the high boost if enough GPU load is there..

By display off the GPU is not working .. just 0Mhz ;) .. also it's running then at very low voltage = 1,00V ;)

Believe me, i don't do such things for the first time.. there is really nothing to optimize.. already lowest power consumptions.. than means lower CPU / GPU for min. won't save more power.. but just makes the phone slow and laggy .. ;)

[Galaxy Ace II Android Development] nikolas1274:
well i am using only your kernel with darkcyanogen and i have NT app too, i have to say that:

1. whan i am using 200-800Mhz all is good without reboots, above that freq i have too much reboots.

2. Bln notification working fine with buttonLed as mention someone some posts before but you have to disable bln from NT.

So the NT app causing problem only when oc cpu
[Galaxy Ace II Android Development] mej69:
I'm using poppmensas last build. With the inbuild kernel, I have no reboots.

When I use your kernel, there are 3 reboots at one day. The screen freezes and after some seconds the device reboots...not nice!!
[Galaxy Ace II Android Development] nikolas1274:
Ace, I think that minimum CPU frequency goes 400MHz when screen goes off, go at CPU setting lock your screen and unlock to see it
[Galaxy Ace II Android Development] ace2nutzer:
On wich kernel ? And wich Governor ??
[Galaxy Ace II Android Development] MarquesYOLO:
Correct, the problem was a freeze system app, solved. I have better battery life, but when screen on down faster.

The problem with the minimum frequency is here too, I set it to 200 but it change almost automatically to 400. Interactive + Sioplus.
[Galaxy Ace II Android Development] ace2nutzer:
Battery

So u guys... I really don't know what is wrong with your Battery.. or Phone usage..

This is my actually Battery stats:
[Galaxy Ace II Android Development] monstro78:
Come on... 3 days and 5 hours screen????

Are you good at Photoshop too as with kernels???

:D:D
[Galaxy Ace II Android Development] ace2nutzer:
hahahahah Nope !! It's really 100% org. !! No Tricks !!

Probably u don't read my Changelogs ;)

I wrote improved Battery Life or so.. but a bit too much :D Next Build will have a little less Battery Life.. because it's safely for the Battery Cycle Life !!!!

@ Min freq 400Mhz Bug:

Can u guys please take a look into this:

/sys/devices/pri_lcd_XXX what do u see ??? The first 3 things is enough ...
[Galaxy Ace II Android Development] nikolas1274:
20141101_p1 & interactive
[Galaxy Ace II Android Development] MarquesYOLO:

How old is your battery? I've heard that battery with more than 1 year and a half loses duration.
[Galaxy Ace II Android Development] nikolas1274:

Subsystem (shortcut)
[Galaxy Ace II Android Development] monstro78:
OK :D:D:D

I just flash your kernel and I use interactive sioplus and 1200oc and I'm going to fully charge.
[Galaxy Ace II Android Development] ace2nutzer:
1,5 Yeahrs... Yeah that's right... but 1,5 Yeahrs is not soo much for a good Li-ion Battery..

Noo, pls check again what i wrote.. u will see_ ws24 or s6d ... That's it ! - Then i will release new Kernel... even with new LiveOPP 2.2 - more stability.. and even New Voltage Table.. because i think it's too inaccurate.. ---> not linear .... :p Also i'll update default Voltages ... thanks to all to provide the AVS File... with this Files we can can write now new Live_OPP Driver with an "default" CPU Voltages that can be run 100% stable with all devices......

Well, but do this not too often... because as i said.. it's not optimal to charge Li-ion batterys nearly to 98% ... The new Driver will charge the batt. only to 92% .. but it shows fine 100% .. this is the 10% Rule of termination current for Li-ion.. to improve Battery cycle Lifetime.

And another thing, The Results in my Screenshot are maked this Way: Brightness, very low.. max: 20% .. Signal + Wifi all the time full signal (that improve battery lifetime) .. and with interactive + sioplus and 200/800 for CPU !!

1200Mhz consumes much more Battery....
[Galaxy Ace II Android Development] nikolas1274:
ws24 for me
[Galaxy Ace II Android Development] MarquesYOLO:
ws24 too.
[Galaxy Ace II Android Development] supachris:
ws24 too.
[Galaxy Ace II Android Development] ace2nutzer:
Thank u guys.. i'll check this Driver... because I've the ws24 too :)

I don't know if it has been asked before. How can I disable BLN without Novathor?
[Galaxy Ace II Android Development] Alex_Gamer:
For now you have more extra ram :D
[Galaxy Ace II Android Development] Maev Maxx Damage:
[MENTION=5840412]ace2nutzer[/MENTION], that settings for novathor app in the third post still available to apply ? I'm talking for Mali boost delay, multicore powersave and mali memory. Thanks for latest build , awesome work!
[Galaxy Ace II Android Development] ace2nutzer:
Already kernel default ;)

U just need (if needed) to oc cpu and gpu..

For gaming set also in nt-app the mali pre.allocated size @ 32 mb.. For non gaming phone: 16mb ;)

Btw i forgot to say in all other builds than codinap f2fs, have always more ram because of disabled f2fs + nfc ! That's why some users have now already 631mb ..

Btw2: next build 631 + maybe 632 mb available :D

network filesystems

Is it still possibly in newest build to access smb network shares?

---------- Post added at 04:48 PM ---------- Previous post was at 04:23 PM ----------

found out: it is (at least with es file explorer, did not test other file explorers)
[Galaxy Ace II Android Development] pablo.see:
ace2nutzer could You add cifs.ko for next build? It's useful for mounting NAS shares on phone and watching movies for example.
[Galaxy Ace II Android Development] ace2nutzer:
Well, i didn't know that somebody need that feature... i've disabled it to making kernel smaller and also to shorten compilation time ... :D

@ smb shares .. + cifs.ko

it's enough if i enable CIFS Filesystem ? or just NFS Filesystem is better ?? don't know ...
[Galaxy Ace II Android Development] snatch_bill:
Great work Ace2nutzer!

by the way I have a weird thing happening!Everytime I end a call(regular call through GSM) when I hit the back button to exit the dialer, facebook auto launches as if it was active and waiting

in the background.Also while using spirit FM radio ,facebook drains 40-45 % of my battery for no reason at all.I have wifi and cell data didabled and I am also on flight mode while this happens.

Any ideas?
[Galaxy Ace II Android Development] ace2nutzer:
@ up

look some latest pages here in the thread.. i've described a way how to disable all receivers from messenger / facebook .. it's actually bug from the apps itselfs, not kernel bug. after that both apps will nor more draining the battery.. also follow and search here how to fix battery drain for google play services.. it's very effective !

Basically i suggest to all users to install betterbatterystats ... with that app u'll find every problem what is causing battery drain.. also u can see wich app/service/receiver is waking up the Phone too much !! (for me it was facebook, messenger, and google play services) ;)
[Galaxy Ace II Android Development] snatch_bill:
Thanks ace.I already have betterbattery stats installed and I already

Disabled facebook autostart - keep awake through app ops.That did not help.I will try

Your method.Thanks again!

I got bootloop with the 0302 codinap f2fs version. Tried 2 times after wipe cache and dalvik. Don't know if the problem comes from me or from the kernel...

Does anyone notice that multitasking weird? I mean when im open aide and open rootex its like aide killed so when i go back to aide its like re open the app and not to last activity saved :( tia
[Galaxy Ace II Android Development] soko3:
I can confirm this...

kernel is smooth, but ram is just a bit better, more free ram, but many apps are killed and i can't switch back to app

i have problems in opera mini when multiple tabs are opened. app is killed and i need to dig in history to reopen them

problem is that system uses too much ram

active apps and cahed apps arent problem...

system is using ram that can't be freed by killing user apps
[Galaxy Ace II Android Development] aish8la:
I flashed 3/02 build last night and changed minfree values to the android default value and used for about 3 hrs and had not encountered any problems ram problems. But when i woke up this morning i saw that battery was dropped from 98 last night to 23 this morning. When i checked android system kept my phone awake for 6 hrs. Don't know if this is kernel problem but other than that everything else is fine.

[Galaxy Ace II Android Development] Vexylle:
Well i found maybe a solution for the Facebook stuff without modifying anything, Facebook Lite, is a lightweight app for facebook and messenger. I'll see if it drains the same ammount of battery as the other 2 app
[Galaxy Ace II Android Development] xo.en:
Erm, am i blind? I am unable to find latest version...everything I can see is old, hm..

Can someone lead me to new version? For 4.4.4, not f2fs version, please..

[Galaxy Ace II Android Development] miryn:
On android 4.3 i had a little more than 3 hours of 'screen on' @25% brightness. On KitKat i have a little more than 2 hours at 25%.

How the situation looks like on Your roms? I'm on crDroid and no, i don't have battery drain by anything.
[Galaxy Ace II Android Development] ace2nutzer:
Check my signature.. i don't have battery draining .. if u're able to use your Android Phone correct...then u'll never had problems, the really best app is betterbatterystats.. u can found every problem for battery draining ... i've only 1% lost for every night (8 hours) by keeping the phone in offline mode.. ( everything off, wlan, BT, sync, nfc, etc..) ;)
[Galaxy Ace II Android Development] miryn:
Yeah but like I said, i don't have battery drain, i have batterystats. On 4.3 i had 1-2% lost per night but in "normal mode" with 3g.. In my opinion, good interpretation of battery is how long it standing with SCREEN ON and how many percents lossing in deep sleep (at night for example).

How many hours of 'screen on' do You usually have?

Btw. Last kernel seems more friendly for battery and pretty much more free ram.
[Galaxy Ace II Android Development] ace2nutzer:
OK .. this is usually not useful question, because every user use different app, have different signal quality on 3G / wifi, and also different Brightness, and to don't forget different ages of batterys .. also different powers for battery like 1500mA (org.) 1700mA , 3200mA etc .. (just approxx)

I hope everybody understand this, and see now this is really useless to ask such questions...

But i tell u anyway my stats: after charging the batt. @ 100%, using the Phone at home @ 2G / wifi and outdoor: 3G / mobile data:

4 hours screen on and inclusive nearly 2 Hours of internet surfing with the stock Browser.. ---> @ home !

Battery is org. SAMSUNG with 1500mA and exactly 2 Years old now :)

Yeah i know :D this is due to disabled much things in kernel.. the less functions enabled, the longer is the battery life :D

But this is not all, next build have "max reduced kernel size" then it should be faster, smoother and again more powersaving ;)

Actually i'm trying to fix sound problems (lock-unlock) what is only present on some phones.. and only after turning the screen on after playing music for 40 - 60 minutes ...

Also i'll optimize more the multitasking without fill the full ram ...

[Galaxy Ace II Android Development] Maev Maxx Damage:
simple report and simple question :3

Yesterday I flashed Paranoid Android beta 5 (6th of August version, from Shine) , your latest and greatest kernel ext4 aaaaand I got slight boost in battery life.

So, ze question - When I install your CM version , latest pico aospa GApps , your kernel, I clean everything I found to be not usefull (cm account, dsp man, email, wallpapers, live wallpapers, appollo , stock gallery, etc) , disable reporting to cm, disable animations and still I got more or less 2 hours screen on. With same usage on Aospa 4.5 I got more than 2½ hours and still 25% remaining. So I thing I do something veeeery very wrong, my batt isnt that bad, just with CM I mess up something. What? :D

One more thing if somebody from Bulgaria reads this thread - Честит празник , земляци!
[Galaxy Ace II Android Development] ace2nutzer:
@up

i think the problem is by deleting all that system apps.. it's really not needed. Most of them cause problems ...
[Galaxy Ace II Android Development] Souffre:
I found the problem : I use link2sd and the latest kernel can't find/mount my ext2 partition.

Nova launcher was linked on it so I got bootloop. Any idea how to fix it?
[Galaxy Ace II Android Development] matthias1976:
"screen on time" is one of the MOST important values to check battery life.

u need complete battery time, the value of "deep sleep", the "screen on time" and the difference between "screen on time" and "awake" to check if maybe an app prevent ur phone from "deep sleep"

i think "screen on time" is very important to check ur battery because its the most battery drainer.

and when the screen is the most drainer u have to reduce brightness to get longer lasting battery.

if isnt screen maybe an app drains or bad siganl quality or rubbish old battery.
[Galaxy Ace II Android Development] ace2nutzer:
Ahh now it's clearly ! ;)

I've disabled ext2 support.. .. Can u just make a backup of that ext2 partition And format in ext4 ? (And copy back the files) ext4 is better than ext2 :)
[Galaxy Ace II Android Development] Souffre:
I'll try it thanks!
[Galaxy Ace II Android Development] xkvegans:
Woohoo... Thank you so much

f2fs + art combined with CWM reparted

Now, no more reason to throw Codina and move to another new device.

Now my codina is close enough to completely perfect for being my soulmate.

Good bye expensive device :cool:

*but, it would be fine if only rely 10MB for sdcard0?
[Galaxy Ace II Android Development] ace2nutzer:
Great ! :o

I use it for months .. and still no problems.. still over 9MB free on sdcard0 .. :)

If there will coming problems in future, we can every time do an repart with bigger sdcard0 .. for ex. 100MB ;)
[Galaxy Ace II Android Development] xkvegans:
9MB free on sdcard0?

But in my case the opposite, 9.99MB used 0.00 Available :confused:
[Galaxy Ace II Android Development] ace2nutzer:
Yeah, format it over settings ---> storages .. but make sure that u don't have swapped storages before trying to format !
[Galaxy Ace II Android Development] xo.en:
You better check what you are installing then :)

btw, you may wany to use disableservice apk to trim working, unused services from installed apps.

IT REALLY CAN CHANGE a lot.

And of course - biggest drainer of battery is usually 3g(that is usually not needed by most people). stick to 2g, if you can.

Is it normal that battery indicator drops to 95-92% in first 30 minutes and down to 85-82 in next 30 minutes? Phone reaches 2 days battery life with no problem. It's normal or something wrong with battery? Or is it maybe battery percentage scale problem?

Yeah it's added in next build again.. sorry i thought nobody need that. :o

U've problem with google play services.. take a look here some pages before.. u'll find a link with a thread how to disable wakelock for google play services ... (very simple.. works without to install an app like disable.services)

com.google.android.gms (): Wakeups: 295 (6,2 / hr.)

EDIT:

delete also that Clean Master App.. that cause also too much wakelocks..

AlarmManager (com.cleanmaster.mguard.Clean Master): 12 m 37 s Count:211 0,4%

To clean the cache, simply under Settings, storages and tap on "cache" that will delete all caches from all apps.

and if u like additionally in cwm: wipe cache ! That's it !
[Galaxy Ace II Android Development] xkvegans:
OK thanks

Another question, I have issue with gps locking location (didn't want to lock my location) :eek:
[Galaxy Ace II Android Development] sercik:
Please some instruction on how to install your kernel and your f2fs rom?

I start from cm11 team canjaca.

1- install kernel

2- reboot to recovery

3- format ssystem, data and cache to fsf2

4- install zip from sd and install your rom.

Is right??

You shouldn't use xtra.bin files, try first remove everything from /data/gps. Than include in system/etc/gps.conf only this:

and save with 644 permissions (rw-r-r). Reboot phone.

Now first toggle GPS to high accuracy and enable mobile data or wifi, you will see now in /data/gps are newest files (Info's about satellites positions). Try now any GPS app.

battery drain

Hi.

I just made clean installation. Wiped data and cache mount, then also dalvik cache.

I installed CM11 rom "cm-11-20141118-UNOFFICIAL-codina_f2fs.zip" and your kernel "codina_kernel_cm11_20150216_f2fs_ace2nutzer.zip".

I have a battery drain after. Battery drained during the night. I have WiFi connection enabled, but I had before too and it wasn't like now.

I checked battery information and I got:

With full battery 11h 57m on battery

Android OS take 41% from battery.

Mobile standby 34%

Phone idle 17%

Screen 3%

Wi-Fi 3%

Android System 3%

What can cause battery drain?

edit (6.3.2015): I flashed the newest kernel in few seconds ago "codina_kernel_cm11_20150302_f2fs_ace2nutzer". Will see if battery drain will persist...
