I've had my new refurb MBA (2.13/128SSD) for 2 days. I really love it!!! The battery charged up pretty fast the first day. This evening is the first time that I'm using the MBA for any length of time on battery power and it's going well. I've had it on for over 2 hours and it shows 2:45 battery time left. Is there any special routine for using the battery and charging right now? Thanks!
