Damager: not sure whether being a 9100T makes a difference. The stock modem was KH1.
nzgeek:joker97: i think my phone is unable to use wifi properly. i have nailed down why my battery now drains at up to 10% per hour!!! wifi!!!
i have to manually turn off wifi when turning screen off otherwise in a few hours the batt is drained. (note: calibrated)
there is no option to set turn off wifi on sleep. this kernel does not allow reporting sleep state - so i have no idea if the phone even sleeps. but probably does, as if i turn off wifi and data (ie 3g) after leaving overnight still 100%.
can it be programs? well i have frozen everything and rebooted so it's most likely wifi ... (or the android OS itself - remember i didnt' clean install, but chose no wipe)
it could be "wifi at work". but why? very strong signal although it has security password - maybe that prevents it sleeping? (forgot to mention overnight with wifi + 3g drains 7-8%)
tried cognition 1.5 and 1.42 ... both are the same in terms of battery use. feels like 1.5 gives me a better modem.
this may or may not help someone ....
Which kernel are you using, and what's your WiFi sleep policy setting?
I'm currently running Hardcore's SpeedMod T40 w/ Cognition 1.5.1 (radio XXKH3), WiFi isn't set to sleep when the screen is turned off, and I'm getting excellent battery life. After a day at work (WiFi connected), an evening at home (WiFi again), and using LightningBug to play sleep music through the speaker for 90 minutes, I still have around 65% battery the next day.
The other thing to check (if you haven't already) is the expanded view of the built-in battery graph (Settings > About phone > Battery usage > tap on the graph at the top). This will show you how often the phone was awake when the screen was off. If you're seeing this, tools like BetterBatteryStats will help track down which process is keeping the phone awake.

wow i still learn new things about my phone! anyway, i've restored back to stock, and haven't reflashed cognition. the only difference i notice is the modem KH3 being superior.
how do i obtain the kh3 modem and flash that on its own? will it work with a 2.3.3 rom/kernel?
Brendan:Damager: not sure whether being a 9100T makes a difference. The stock modem was KH1.
It can.
The i9100T has a less powerful radio in it for some reason, not all modem code takes account of that I guess...

Interesting as i always had full bars with stock KH1 and KH3, but KG6 gives me just 3 or 4 at anytime.. Very strange

Not strange at all lol.
The KH3 modem must have been programmed with the i9100T in mind.
Some of these other modems may never have been intended for the i9100T, and would normally never get it (I presume). But when they have people manually hacking and flashing modems outside of the official update system....
Well, we take our chances. Usually we win; sometimes we don't.
And the best you can hope for is to Download Mode before you sleep...
(Whispers of Kenny Rogers The Gambler float in off the wind lol)...
Kelem: Awesome guide Brendan and the many others involved.
Thank you.
Kelem: Hello,
In the process of upgrading my SGS2, to a newer rom and having forgotten how i did it last time, i managed to completely factory reset my phone, that i consider good news. it could have been alot worse.
I will take the opportunity to redo root, get rid of that yellow triangle, and install a much newer custom rom that's stable, and possibly better bluetooth support.
Just checked and still have root on my phone so , does that mean i just need a custom rom?
I will read the howto to check
I also have CWM installed.
