I'm currently using Captivate MIUI 1.6.3. I have been using MIUI ROM from the version 1.5.13 (2011/05/13) And I was disappointed by the fact that not one have reported this bug or have fixed this bug... Anyway, for what I have observed... Battery drown really fast from 100~80%, and noticeably slow down afterward... Please fix it, so it's showing up almost exact percentage of the battery~~~~!!! P.S. Sometimes, battery only charges up to 98/96%!
