I'm REALLY enjoying Cognition 1.31 on my Bell SGS2.
Charged my phone to full, unplugged it, went to bed and woke up 6 hours later to 100% battery. This would have been 96% on stock ROM. Using Juice Defender pro on stock balanced profile, ATK app killer set to kill on screen off and undervolting my CPU. Also using GO-Launcher which some claim drains the battery, I just don't see it tho. I was at 73% battery after 18 hours of light use yesterday. 1 hour 34 mins screen time with 15 mins worth of calls and about 1 hour of browsing via 3g + about 12 text messages.
Anyway it's actually extremely easy to install Cognition 1.31 now that u have the phone rooted...
here is the link: http://forum.xda-developers.com/show....php?t=1124396
follow the instructions to the dot.
Esssentially u take the ROM file... transfer it from your computer to your phone and u install it from your phone using CWM.
That ROM however doesnt come with social hub (I love to have facebook update my callendar with events/ people's birthdays so they dont think im a douchebag for not saying HBD) but u can reinstall it as the dev was kind enough to include packages of all the apps he stripped down from that OS.Edited by Scorpion667 - 8/4/11 at 11:53am
