I had the Flex 2 for about 4 months now and the battery usually lasts 3 or 4 days. But since last week the battery barely lasts 5 hrs. So I thought the tracker gave away and bought a new one a few days back. With same result! When the tracker shows battery below 10% I hooked it to the charger and reset it, battery goes up to where it should be (e.g 70%). I’ve tried reinstalling the app and the tracker but no luck. Anyone?
