Get battery state from command line:
Start xterminal and write: lshal|grep battery
after that you should get a lot’s of line about batter but line “battery.charge_level.percentage” is what you want to find.
Of course you could just write lshal|grep percentage
and then you get line “battery.charge_level.percentage = 40 (0x28) (int)” which means that my battery stat is 40%

Get rid of that “Nokia hands” video when you start your phone:
Edit file: /etc/hildon-welcome.d/default.conf and comment line:

away with # mark so that it will look like this:
#filename=Hands-v32-h264.avi
and save that file.
