I seem to have the same problem.
Ubuntu ver: Ubuntu 10.04.1 LTS UNR i686 upower ver: daemon-version: 0.9.1-1 kernel ver: 2.6.32-30-generic system info: Dell Mini 9 (Inspiron 910); BIOS v. A04; 32WHR 4C Lithium Simplo battery
Went from 100% charged on AC power to 87% in about 3 minutes. Plugged it back in and it went from 85% to 100% in about a minute.
