Our 2007 X3 would each a battery every year. Turns out that the TCU (telephone ? unit) was not disconnecting from the mobile phone properly when the car was turned off. This ran the battery down and then issues like moving the power seats while the car was off would not function properly. This would not explain your condition unless the battery was just about dead. If you don't see green on the battery eye then its time for a new battery. If the battery is OK, then you have some other intermitent electrical issue going on.
