This rom is really kicking. Everything seems more fluid compared to stock+xionia I was using. I get way more memory out of this, too. With all my apps installed on stock+xionia I had about 21MB free. Here, I have 69MB.
I'm currently clocked at stock 600mhz. Compared to the stock+xionia rom, this uses way more battery. Well, unless my SetCPU froze at 600max, 245min, ondemand, even while the screen was off (which the profile is supposed to be 245max, 125min, conservative) because the widget never refreshed, which I assume means it's still clocking at that speed. If the clocking speeds did freeze then that's why my battery drained so much (100-68% in about 7hrs while I was sleeping).
How are your battery lives?
Edit: I notice when receiving a call, ringtones don't repeat. So the built-in short 1 second ringtones will only ring once.
