My Zip has had a problem with battery icon flashing. I had one battery last nearly 11 weeks, a record, well done, thought I. The next one only lasted a few hours. What's wrong? And now the icon was flashing again, on the new Duracell that I put in yesterday. I took it out and replaced it, it was still flashing. I waved it around, the flashing stopped, and then synced it, losing about 2k paces, and the dashboard said low battery. I synced it again five minutes later, and the dashboard said medium battery. Why?
