Hi,
this is a common symptom of dying battery. Same for NiMH AA/AAA cells, battery packs etc. - simple chargers indicate fully charged state after much shorter time and the device also switches off after much shorter time of working. I remember this from the time Nokia 3310 was a brand new phone :-D
