It only looks like it’s “charging” when your battery is not yet totally empty. But during that process, your battery will eventually drain out... and... when you try to re-charge it... it never does... and you don't hear the usual “beep” that you hear on a “working” n80i. Luckily, my cousin has the n80 silver edition and i tried charging “my” batteries thru his phone and the battery would work fine once i put it in my n80i phone. i also waited till my cousin’s n80 battery drained off to test on my n80i... and... the same problem happened... it just does “not” charge. tried different chargers... including an “authentic” NOKIA N80/N80i chargers... still no luck... the Nokia Care stores in Manila, Philippines seemed to have lost their way about this issue... and when i ask them what’s wrong, they kept on saying “it’s the battery!” or “it’s the charger!”... well, i think it’s the “phone” itself... i troubleshot so i must be right.
