I have had my Elemnt for about 18 months. In the last week, it was going from 100% battery to flat in about 2.5hrs. I have done a factory reset and charged it up to 100%. It's been sat on the dustbin outside in auto-pause mode or about 2.5hrs and battery has dropped to 19%. What sort of battery life do others get ? I use the Elemnt about 4 times per week and would expect better battery life than 18 months.
