for battery life,
-keep your brightness low when indoors.
-shift to custom rom+kernel(if on stock rom)
-switch off background data
-switch off sync when not needed
-keep ur overclock within acceptable limits. Using smartass instead of performance governor. It gives better benchmarks and throttles down the freq when load is less or on standby
-avoid google maps. It runs in the background unknowingly at times. Ive uninstalled it for good
-if still not getting acceptable battery backup, make sure u calibrate ur battery. First wipe battery stats from the recovery and reinstall kernel and again wipe the battery stats. Then charge the battery completely and use. Else use battery calibration app from the market
ppl looking to get a new phone in the mid range shud wait a little. Im hoping the xiaomi MIUI phone will release here. It will drive prices down of other phones too.
Optimus one was and still is a very good phone....
Andy's Rom will be the ultimate ROM and a worthy ROM to this phone. If andy's word is to be believed(which I do) this rom has been tweaked as much as possible. So I dont think there will be any other GB ROM to compete. I doubt tht development will be as fierce as it was before. O1 XDA forum has gone thanda after dr.notors issue. Hopefully ICS will revive some enthusiasm.
