[Q] Battery calibration messed up my battery

view story

http://forum.xda-developers.com – Hi. I used Battery Calibration from google play exactly as instructed. Since then, my battery is charging REALLY slow, or not at all. When I use my fully charged galaxy after its charged overnight(connected to a charger) it shows 100%, and when I disconnect it, the battery drops... To lets say 92%. What can I do to fix this? Thanks in advance. (HowTos)
