Yes, secril_fd-interface wakelock is the main wakelock to look for.

But IMO its influence to you battery life might be "compensated" by other wakelocks.

So I would mainly check the overall influence/difference for your battery life ... and the deep sleep ratio.

1. Test run (idle or usage) for a dedicated period of time with FD disabled > check battery loss and deep sleep ratio.

2. Test run (idle or usage) for the same duration and without changing anything except enabling FD > check battery loss and deep sleep ratio.

Then compare if you can recognize a significant difference of battery loss and/or deep sleep ratio in the two tests.

Keep on mind to enable mobile data connection ;)

I once have done a similar test (I think it was on the first, leaked JB ROM) ... and I had a significantly higher battery loss and lower deep sleep ratio with FD enabled.

But I haven't tested it again on later ROM versions.

Can you please share your governer settings?
[Galaxy S II General] It_ler:
I'm on kernel default settings ... cfq / ondemand.
[Galaxy S II General] championc:
On Apolo v4.9 regular, I was getting decent battery on the default zzmoove / cfg but I changed to try pegasusq / sio which is so much better. However, Pegasusq / noop is looking like it could be even better. Maybe It_ler you could try and confirm for all of your followers
[Galaxy S II General] It_ler:
IMO scheduler and governor can have influence to your battery life related to your usage.

As everyone has a different usage, a battery friendly scheduler/governor for one user may lead to worse battery life for another user.

I don't want to test all available scheduler/governor combinations. And the best combination for you may be better on my phone ... but it could also be worse on my phone.

If many kernel users report better battery life on a special combination, I surly will test it too.
[Galaxy S II General] championc:
I was possibly incorrect in that I think noop is not any better.

I would suggest that some others try Pegasusq / sio for maybe 24 hrs.
[Galaxy S II General] hawkdown77:
Try sio or noop?
[Galaxy S II General] championc:
I already said that I found Pegasusq / sio to be better than the default ....... MUCH better !!
[Galaxy S II General] bobdoblo:
Pegasusq + sio here too.

But all my best battery times have been on Ondemand + Noop;)

Edit, why am i on Pegasusq + sio then? :rolleyes:

[Galaxy S II General] bogdan1980:
I test for long time gov and iq, plus overclocking.

100% stable is ondemand/hyper, sio/row iq for awake. Pegasus for me is not stable.

For sleep, ondemand plus noop.

Noop is the best at battery but sio is faster.

If i use sio for example in gta3 i see 22 fps minimum. With cfq 15fps.

Ps i use fps meter for frame rates, it's like Fraps on PC.

[Galaxy S II General] -Dzony-:
First of all I want to say hello to all of you. I installed Apolo 4.9 regular, first course, I used hawkerpaul's kernel wipe script and at the end wipe cache and dalvik. After that I installed the CRTOFF mod, but then it started to behave crazy :) . When the screen is turned off and when I just want to see what time it is (press home or power button), and when I want to lock it again, sometimes the screen flashes a couple of times and then I have to unlock it and lock again or to leave it for a few seconds and the screen will shut itself off. This is my first apolo kernel, I was always on Philz. Sorry for writing this in your thread, I wanted to ask in apolo's but I can't (new members with fewer than 10 posts). I'm using NeatRom Lite 4.8
[Galaxy S II General] bodomfan:
I use apolo 4.9 regular and don't get that sort of behavior works spot on like it should
[Galaxy S II General] It_ler:
Restore your last nandroid backup if available.

If not, just reflash the ROM.

Try Apolo light to check if it is UV issue.

Does the mod work fine on PhilZ kernel?
[Galaxy S II General] -Dzony-:
My last nand backup contains PhilZ kernel. I should probably once again use hawkerpaul's script and install Apolo light? CRTOFF on PhilZ only works when wifi is on. I will try to do what you told me and report back.
[Galaxy S II General] It_ler:
Maybe you should try to flash Apolo kernel without wipe first.
[Galaxy S II General] -Dzony-:
Should I first restore my backup and then flash lite kernel (without hawkerpaul's script), or just to flash lite over regular?
[Galaxy S II General] It_ler:
Restore your last nandroid backup, ensure that CRT ON/OFF mod works fine and then flash Apolo light non-wipe.
[Galaxy S II General] It_ler:
Oh wait ... just got a new idea.

Have you enabled CRT OFF in recovery?

Apolo kernel has this option in Kernel Extras.

Then reboot and try again.
[Galaxy S II General] -Dzony-:
I have already restored my backup. :) I enabled CRT OFF in Apolo recovery, but I also installed XWLSW_CRTOff mod. Maybe I shouldn't install that mod, but just to turn CRT OFF in Apolo recovery...
[Galaxy S II General] It_ler:
I think that only enabling the CRT OFF option in recovery isn't enough.

At least it could not bring the CRT OFF effect to my phone.

So I assume that the mod has to be flashed additionally.

Does it work on your phone now?
[Galaxy S II General] -Dzony-:
I also tried to enable CRT OFF option in recovery but as you said, it isn't enough. I had to install CRT OFF mode and tried it on apolo light, but the screen flashing is still there, but not as often as in the regular version. Don't know what else I can try, maybe I should wait for 4.10 version... :)
[Galaxy S II General] Downisthenewup:
Brilliant! been looking for something like this.

Surely Dzony that 5.0 is after 4.9. The other option could of course be 4.91

Test for test for NeatROM Lite 4.9 and Superlite NeatROM v1

Will test for NeatROM Lite 4.9 and Superlite NeatROM v1? (Battery and benchmark)

Thank you for answer!
[Galaxy S II General] It_ler:
1. I'm very busy ATM ... traveling for the company. So less time to flash and test new ROM versions.

2. AFAIK new NeatROM version is still the same base stock ROM ... only new/more mods ... and maybe more/other pre-removed apps. So I don't expect significant differences for performance and battery life. Maybe with more removed apps ... but this can also be achieved on v4.8 by manually removed those apps.

Just my 2 cents.

I am more keen on testing new kernels/kernel versions.

Will continue my tests as soon as I have a little bit more time ... and when back home.
[Galaxy S II General] It_ler:
Sorry for the "break".

Very busy and traveling ATM.

So I cannot test under same conditions.

But I flashed Apolo kernel v4.10 regular.

It's stable on my phone.

Everything seems to work fine.

Nice brightness configuration settings in New Apolo Configurator :thumbup:

I am very curious about its battery life.

Not really mate, i noticed more wakelocks with fd in them that aren't usually there so i turned it off again.

I could probably do a better test now as i don't use my S2 much now.

Watch this space....

I do know one thing, noop is definitely better for sleep. I always thought it was and now this basically confirms it.

I changed my S4 to noop (ondemand + noop) yesterday and this morning i woke up to 6 hours @ 100% still just like i could do on S2.

i use the same rom and kernel but i do face a serious problem with wifi

it drains battery like hell , doesn't let the phone to fall in deep sleep it stays at 200Mhz when wifi is connected and i cant find why this happens

keep up the good work proving that there is always room for improvement
[Galaxy S II General] It_ler:
That's why I am using Better Wifi On Off app. It turns off wifi when phone is running on battery and screen is off.

(Works better than advanced wifi settings in system's menu IMO.)

But if your phone keeps running on 200 MHz, there might be another culprit.

Check your wakelocks and alarms in BBS and post an IDLE dump.

P.S.:

I have very light usage. On heavy usage, my battery life is worse too.

EDIT:

Added some screenshots:
[Galaxy S II General] It_ler:
Nearly no deep sleep (2,3%).

That's really bad.

Biggest wakelock is:

"wlan_rx_wake" (): 7 h 41 m 3 s (27663 s) Cnt:(c/wc/ec)10864/0/10863 83,2%

So something is using your wifi connection nearly all the time.

Try again with wifi turned off ... 4 hours of doing nothing is enough to get reliable results.

If your battery life is significantly better with wifi turned off, you should use Better Wifi On Off app to turn wifi off as soon as the screen turns off.

But there could be another issue in your wifi settings/network.

To find this, you may have to check your battery life when using another wifi network. If it's better, then it seems to be an issue in your wifi network.

There are some methods to search for very communicative wifi devices (Wireshark or Shark from Play store).

For more detailed information you can post in BBS thread. There are more "experts" on this matter.

Have a look at BBS thread => http://xdaforums.com/showthread.php?t=1179809

If you look at "Other" and the phone was in deep sleep, BBS will show you the deep sleep time and ratio.

If you want to test for a short period of time, go to app menu More > Set Custom Ref.

Then turn off the screen, let the phone "sleep" for a while.

Afterwards open BBS again, switch to "Since Custom Ref." and "Other" and have a lok at the deep sleep time.

Kernel plays a major role on battery life and wake locks. Since you put same old lq5 kernel on the new 4.0.4 Roms, your results are biased. Also, lq5 is very bad on battery. Until chainfire updates again the i9100, you should flash stock kernel before your tests
[Galaxy S II General] It_ler:
I know ... will flash corresponding CF-Root kernel as soon as Chainfire will release them.

But for XWLPM, I have already re-done the tests with pre-rooted stock kernel (from LiquidPerfection@XDA), had had nearly the same results as before ... with CF-Root for XXLQ5.
