my DHD currently on MIUI 1.2.11 latest version (ts please update in rom developement

).. a bit review about this rom..
- MIUI bootloader screen are very nice, i like their bootloader screen and their UI.
- i found out sliding from one page to another are not smooth (a bit lag) like other ROM.. i.e Leedroid / RevoHD.. (my previous ROM)
- when scrolling up / down page also not smooth..
- bluetooth headset not functioning, but transfer data via b/tooth was ok..
-
FOR BATTERY USAGE STATISTIC: (Important) * after done flashing ROM, battery got 94%
* set to GSM mode, on wi-fi to download few apps, sync google acc, update FB status, surfing internet a bit, update album cover art etc etc
* within 30minutes, battery drop 86%..

(for me, not as good as Leedroid / revoHD)
- so i flash custom kernel LeeDroid V2.0.2, just thought maybe can improve battery a bit.. and......~ i'm disappointed b'coz battery dropped fast..
- even i cannot turn on bluetooth at all when on leedroid kernel.. so i decided to flash another kernel.. it's Buzz kernel 1.2.3 OC/UV
- same result, cannot turn on b/tooth at all, battery also not improve..
- in idle mode / screen off, i tried to monitor battery usage.. started from 81% from 12.14am until 12.54am, on screen and battery 78%..
- but never mind, just want to monitor MIUI rom for about 2days and see got improvement or not..
