using teamhacksung build 17 ROM + semaphore 0.9.5b and recently flashed KF1 modem, and wow the battery life is improved so much longer

opps forget to add that my phone now on 1850mAh battery as well.

Normally at Sleep(phone with data) takes around 20 minutes to drop 1%

after new modem, takes >30 minutes, one think I notice is when not using any data, it will fall back to normal 3g only when you use data it will switch on HSDPA, unlike last time the phone will always be on HSDPA

Btw, I started with KF1, tested ok with HSDPA,3g and 2g

when go to KB3, weird things happen at first HSDPA was working, then when force to 2g, it stays there forever even after reboot, reflash KB3 and I never got back HSDPA or even 3g.

So went back on KF1 and never look back
