H120 charging problem!
My rockboxed H120 just got a charging problem! When i plug in the charger, the battery level indicator raise to 100% quickly. And after i plug off the charger when the charging light went out, the indicator drop from 100% quickly and after a while it raise up again but did not reach 100%. Before this strange thing happened, the charging light was blinking the last time i charged my H120. Anyone knows where is the problem? Is this problem with the battery or with the charging circuit THX in advance!
