Hi @Preti It's entirely possible that your Alta has reached the end of it's life. If multiple restarts won't revive it, it's close to dying. Try restarting it a few times and see if it helps. I've had this happen before when I couldn't get my Flex to hold a charge for very long and it ultimately died. Mother's Day sales ought to be announced soon, so take a look at what could be your new Fitbit.
