samsung galaxy s2 never charges fully!!

[johnny_claude2002]

Hi,
when I try to charge my samsung galaxy s2, it starts charging. However charging stops randomly at different percentages (never reaching 100%) with the phone telling me "charged". does anyone know what is that ?
Thank you,

Welcome to the forums.
I would guess you have a bad battery, especially if that one is the original.
