Hi, My 10-year old Garmin Forerunner 305 has a dying battery. it can no longer hold a charge for more than 28 minutes or so before coming up with a battery low warning. Not very handy as my regular run is about 38 minutes duration. The battery cannot be replaced. Any ides for extending its life? Would regularly deleting historic data after upload reduce the normal current consumption and allow it to keep going for a bit longer? Perhaps it is time to say farewell faithful friend.
