Hi, It seems to happen too and a known bug in CM7 roms. The charging led turns green when battery is charged to 90%, but keeps on charging to 100%. Its just the notification ( green led) that doesn't match with the charge status ( 100%). Clearing battery stats and removing them doesn't solve issue. Also when i updated to 1.4.15 i did a setup from scratch and i should have a clear battery stats file. I updated to 1.4.22 and the bug persists. Its not a big deal though, because the battery charge to full and on switch pro widget icon i can see its fully charged. Anyway if it could be solved in future Roms it would be nice.
