Ok as promised my report back, firstly like previous versions this ROM is very fast and smooth,absolute no problems there, battery life though appears to have sadly gotten worse with the last 2 updates.

On version 1.15 i managed to get 26 hours 58 minutes which i was delighted with, this is with medium to heavy Internet usage,about an hour of music, about 5 calls,10/15 texts (battery was at 100% when i started)

On version 1.20 i managed to get 23 hours 28 minutes, usage was slightly lighter than 1.15, however i did have 2 widgets on my screen Engadget and goal.com so i suspect they might have have something to do with the lesser battery life.(battery was at 100% when i started)

I've just tested version 1.30 i actually froze more Samsung apps in Titanium Backup too so had high hopes battery life would be even better, you can see from the screenshots i got 22 hours 10 minutes, this is with low to medium Internet usage, 45 minutes music, 1 call and about 15 texts, i also booted into recovery 4 times as i was flashing different boot animations so i know that obviously took away some battery life,again the 2 widgets were there Engadget and goal.com but overall it's a little disappointing, ive lost nearly 4 hours from 1.15 to 1.30,as i said the widgets might have something to do with it but i don't think they are the root cause, a look into system panel doesn't reveal much from what i seen on previous versions the same apps are there, the Android OS however has gone down but not by a great deal, so in my last "test" im going to restore 1.15 and put the 2 widgets Engadget and goal.com on my screen and ill leave the phone on overnight and have medium to heavy internet usage and then ill know for sure if that version really is better as regards battery life or not.(Battery was at 98% when i started this test)

Sorry for the long post but i believe it's important that people do tests like this as it benefits most people and of course DG as regards going forward and improving.:)

2 Questions:

1) I like the new market, and I REALLY like how when you go to update an app it lists the changes at the top of the page instead of needing to scroll down through the entire description...but I swear it takes much longer to navigate and search and I keep getting connection errors vs. the old market. Anyone else notice this?

2) Is there a way to update Samsung Apps like AllShare, Music, Email, Internet Browser, etc...? Cuz I still use several of the stock apps Samsung included that aren't available on the marketplace, so I can't update them the way other apps are updated, and it seems the 'Samsung Apps' app has been removed from the ROM, so is there another way, because I find it hard to believe that these apps wouldn't have ANY updates...
[Galaxy S II Android Development] Guitarfreak26:
Wouldn't any battery issues be more to do with the kernel update? I'm doing a calibration so can't comment yet

1.31 Phone FC after call!

*I did full wipe/cache/data... before installing 1.31
[Galaxy S II Android Development] jonny68:
It's a possibility sure but having read some comments on the Ninphetamine Kernel thread some people are saying that battery life has gotten better (i dunno what ROM they are running) so not exactly sure.

I am going to restore 1.15 and put the 2 widgets on my screen and have about the same usage as i did last week with 1.15,medium to heavy Internet usage,etc and leave the phone on until battery dies so i can know for sure but it does look like that battery life on 1.15 is superior.
[Galaxy S II Android Development] Rich_RH:
Hey Johnny, have you made comparisons with 1.13? Personally I feel that while my phone idles it drains pretty quickly with 1.2 and 1.3 but with 1.13 its pretty steady.
[Galaxy S II Android Development] Gawis:
wauw, that's helpfull

DG will be very happy with your input...

Mine works fine btw...
[Galaxy S II Android Development] jonny68:
I didn't make a backup of 1.13 i should have really i don't recall testing the battery life properly on that version.

GingerCocoTheme compatible with Cognition 1.31!!

-CallRec added in the theme.

-Another order for the notification toggles.

Because of my bad english i dont post it in XDA.

[Galaxy S II Android Development] BuzzFuzz:
Helpfull or not, we are here to exchange opinions...

This has also happened before two or three versions. Im not sure now.

I did full wipe/cache/data... before installing 1.31, like always.

Interesting, phone worked all day without any FC, now after last call FC.

+ GPS , can't find satellite

I will once again wipe and we will see
[Galaxy S II Android Development] budco2000:
i been using this ROM on my SGS2 since the release. But with 1.31 I can't get no satellite lock. 1.30 worked fine. Hell, every version has worked flawless. I done 2 complete full wipes and re-flashed 1.31 3 times and still after 15 minutes no lock. It sees 11 satellites with good strength. GPS Status, GPS Test Plus, Maps, Navigation, or my 40 dollar navigon app where maps are stored on phone and does not require a data connection all cannot get a lock. Tried CM7 and got a 10 satellite lock in 8 seconds, but i don't like cm7, i like what i have. Cognition. As a taxi driver, GPS is a must

Update. 1.20 worked, 1.31 still does not, which leads me to believe its the kernel
[Galaxy S II Android Development] andyiacovou:
Hi everyone

I need some help, im really stuck.

I flashed the latest Cognition 1.31 and all was working perfectly. I then went back into recovery and the phone is now stuck with a symbol with a hat on it and an arrow. I can see the CWM menu with all the options but what ever I choose sends me back to the symbol. Tried powering off and on and removing battery no luck.

Any suggestions would be really appreciated
[Galaxy S II Android Development] fgvalle:
What are you using to select in the cwm menu? For some reason it changed on me from the power button (now its 'back') to the menu button. Give it a try and let me know if that helps.
[Galaxy S II Android Development] deimos86:
I think this it..

If you have CW Version 4.0.0.2 something like that the power key will do that insted of selecting the option. use the back softkey until you get to rebot the system and use the "Home Button" the one in the middle to select the option.

In other versions of the recovery the power buttown does work as enter the option.
[Galaxy S II Android Development] jonny68:
DG a request, i seen this on the latest chagelog on Baptista ROM and i think it would be a great addition to Cognition.;)

Does someone has this, will the KG2 broser fix would work in this build?:confused:
[Galaxy S II Android Development] andyiacovou:
Thanks guys, that was the problem, I was getting really worried there for a minute :)
[Galaxy S II Android Development] kbiz90:
1.) I think it's called SamsungWidget_News.apk and it's in the removed apps link in post 1.

2.) I don't think you can toggle GPS in Tasker on Gingerbread. Sucks. It's possible CM7 may be able to do it, but there is no RC for it yet.

[Galaxy S II Android Development] jonny68:
Just flashed SpeedMod SGS2 [K1-T9]Kernel so will test out 1.30 battery life with this see it makes any difference.

edit - Might not work properly with SetCPU ive asked the question in that thread, seen on the OP though

So SetCPU might not actually be needed??

[Galaxy S II Android Development] amadablam:
Flashed 1.30 yesterday and all good. Flashed Ninphetamine version 2.0.2 shortly afterwards.

Everything is going really well. The market is quicker for me than on 1.20.

Since a full charge, I have the phone on 11 hours 32 minutes and its still at 76% battery . This is with data all day with some wifi connectivity, push email, gtalk, 20+sms messages and over an hour of calls so far.

Android OS is at 18% and Android System is 13%

By the graph, the biggest drain on the battery was when I was on Wifi.

Very happy with it so far and will report back but unless the battery plummets, every seems really great so far and I am really glad of the upgrade and it works well with the kernel for me. I am not over clocked either so maybe thats helping.

Keep up the good work DG!
[Galaxy S II Android Development] jonny68:
That does seem like exceptional battery life have you freezed all Samsung apps, do you not have any widgets,do you use Juice defender,etc?
[Galaxy S II Android Development] amadablam:
Thanks Jonny.

I have not frozen anything but I free up RAM with task manager a few times a day (closes about 18-21 applications each time). The only widgets I use is Fancy Widget clock/weather with refresh disabled, Google Search and Power saving widget.

dont have GPS enabled unless to update weather quickly but I get a signal indoors in under 10 seconds. also I am using Go launcher Ex and Go sms over the standard sms package and I use Maildroid for email and Boat mini browser for surfing.
[Galaxy S II Android Development] jonny68:
Sounds good i don't use a task killer myself but i have Juice Defender Plus and it has worked but im going to get Juice Defender Ultimate,not cheap at €4.99 but i hear it's brilliant for battery life.

Also on a separate note ive gone back to Ninphetamine Kernel for now as the other one Speed Mod K1-T9 doesn't appear to work with SepCPU and no recovery is included with this Kernel.

I better get to bed soon ive a very early flight tomorrow morning:o;)
[Galaxy S II Android Development] amadablam:
Yeah I am very impressed with the battery life and the ROM is a joy to use.

Its unfortunate that some people are having issues with GPS and other items but I am luckily only having good experiences from this rom and kernel combo.

Will be interested to hear how you get on with JD ultimate. :)

Thanks for sharing your experience with the Kernel too.
[Galaxy S II Android Development] y0.o!:
bug report maybe?

When I make a call and the line is busy the phone tells me so, hangs then the screen goes off. The screen only goes off if I don't touch the screen before it ends the call. To stop the screen turning off you have to touch it some where before it hangs up other wise it will turn off.

It's annoying if your having to keep redialling the same number over and over to get through to some one (was making a doctors appointment, we have to ring at 8am only for some reason). Would be better if it didn't turn the screen off at all after a busy line, just put you back to the dialler and that's it. You screen time out settings are still in place.

I hope I've explained it well... if not just ask I'll have another go. My screen off is set to 10 mins so it isn't this function, I did many tests turned the screen off then on and made the call etc, it's not that.

Thank you for your efforts yet again, great work so far :-)

JD Ultimate is worth the money if you are concerned about battery life and has a lot of options. I keep it on balanced settings and have never run out of battery and I have an extra Samsung battery and dock/charger. Never needed it.
[Galaxy S II Android Development] codington:
1.30 is still rooted. What is missing is the superuser apk from Chainfire. You could install superuser from the market - reboot and all is back to normal.
[Galaxy S II Android Development] knightnz:
Here's another possibly useful bluetooth A2DP fix thread:

http://xdaforums.com/showthread.php?t=708685&page=10

Looks like the issue is fixed in current Gingerbread AOSP, and hence in CM7, but the Samsung kernel still uses a fixed bitpool resulting in poorer quality A2DP audio.

Any chance of implementing the fix in Cognition? Looks like it'd involve replacing the whole bluetooth stack with either the AOSP standard version, or preferably the CM7 BlueZ stack which would likely be a major job though. :(
[Galaxy S II Android Development] yiannisthegreek:
This is what I did but... After I reinstalled Superuser from the market, it kept "forceclosing" on me when trying to access apps that require root (titanium backup, root explorer, etc). I rebooted and then tried Titanium Backup again and it searched for "root rights" and then told me that my phone was NOT rooted.

I then reinstalled v1.30 again and the exact same thing happened to me and so I went back to v1.20 and now everything is working like it should.
[Galaxy S II Android Development] synxx:
someone has already posted this workaround so i take no credit. but if u copy the superuser.apk from system/apps while on v1.20 to ur pc, then update ur phone rom to v1.30. then copy the superuser.apk back to system/apps on your phone you will have superuser back. thats another way round it. also the force close issue. i also have that problem but it doesnt deny me root. just when i open superuser app it says it was force closed but still opens superuser anyway!? dont quiet get it really but its no biggie as it still works. try what i said and report back :D

[Galaxy S II Android Development] knightnz:
Works fine here.

As always when you have problems, wipe the data+cache for the application via Settings --> Applications --> All, then boot to recovery and wipe cache + dalvik, then reboot and try again. If possible, also re-install the Maps application if you're running a market updated version.
[Galaxy S II Android Development] Guitarfreak26:
What does balanced do? Update your apps every 15 min or something
[Galaxy S II Android Development] knightnz:
I just noticed that 1.31 has a largely default /etc/bluetooth/audio.conf file which doesn't have HFP enabled. Is this intentional or is it now using a .conf from elsewhere in the filesystem?
[Galaxy S II Android Development] kbiz90:
Love the end of your sig. :D

You can try this after you flash:

http://xdaforums.com/showpost.php?p=15973860&postcount=4977

Personally, I moved SU and CWM to my internal storage before I flashed and moved it back after. No problems.

Others have done a bunch of other things. Lots of different success stories since 1.30/1.31 was available.

You could also wait for designgears to fix the problem. However, who wants to wait??? :D
[Galaxy S II Android Development] KLoNe1:
I've found a bug (which was also present in 1.30) - when unlocking the device and returning from the lockscreen, the screen doesn't 'fade' back down into the homescreen anymore, it seems to 'shrink'.

I've made a video to explain better. Very annoying: http://www.youtube.com/watch?v=ih87J0PiR4g

I have noticed lately that when I push the home button it goes to the desk clock app and I have no way to get back to the homescreen until I reboot it. Starts doing this after a couple days. Just a random bug..?
[Galaxy S II Android Development] AllanJacques:
From infos I couldn't figure out if browser is laggy or not...

So, is it?
[Galaxy S II Android Development] DarkDvr:
Strange...

I used a custom Email.apk (from one of the devs here) on Cognition 1.15 that has bypassed Exchange security.. and it worked fine.

Now, on 1.31 I've tried 2 different ones and it seems bypass no longer works. It requires me to set up a password and refuses to sync.

Any idea what changed?

EDIT: FIXED. Weird though - when renaming Email.apk in Root Explorer to Email_Orig.apk, it kept the reference to it, and when setting up account, it didn't use the new Email.apk, but still used Email_Orig.apk (even after reboot).

Complete uninstall of Email.apk, reboot, copy new Email.apk, then setup the account - worked.
[Galaxy S II Android Development] designgears:
Probably to do with your theming / launcher choice. It is not like that stock. (very likely the launcher)

Be sure to check on a stock Cognition setup before reporting to reduce clutter.

Sure you aren't at the lock screen? lol

I can't reproduce it..

are you clearing dalvik-cache and data on the email app after doing that?
[Galaxy S II Android Development] knightnz:
Seeing as it's De-Odexed, yes.

Use Dolphin-HD instead, it's far superior in both speed and functionality.

My logcat shows this on every boot, I guess these apps/packages are quite useless since packagemanager keeps ignoring them (not installing them) due to missing signatures...?

I did a battery calibration and let the battery run out over night and i noticed, that the idle battery consumption dropped considerably while going below ~12% (see screenshot! all of the last hours where with screen off, all syncs etc on)

there seems to be some additional power saving mode kicking in (no, i didnt enable the "power save mode" in the settings).

maybe this could be used to improve the battery life in idle mode? has anyone experienced this behavior?

Hope this battery drain will be solved soon.

As for now . my old HTC Legend lasts longer on one charge.

go back to your HTC then. use some apps and track the rogue app that is producing the drain. also dont expect dual core device with huge screen last 3 days! and if u r not satisfied go find out how is HTC performing in terms of battery. 12h or less!

And can u share with us how to set up the 1hour update interval? thanks
