Recently my TicWatch S has started force shutting down with 70-100% still remaining. The first time it happened I was finishing a run and it powered off but since then it only lasts about 5 minutes powered on before shutting down even when at 100%. It then won't power on again until I connect to power and then it turns back on and says 90ish % so clearly has enough battery.
I have tried factory resetting but didn't help. Any suggestions or has my watch given up on me?
