Hi all! I was going to run with the Nike Run Club app (strong recommendation for anyone who wants to start running) on my watch without my phone (I own a Series 4 mobile). My watch played music through my Airpods pro.
About 5 minutes into the race, the clock ran out completely. black screen, no music. and then shortly after start-up (indicating that it had lost power). Then it is displayed with “critical” battery (10%). I gave up music and NRC and did just the built-in training runner.
Annoyingly, it continued to say that it had 10% battery for about 4 hours after driving, and now that I have connected it to the charger, it very quickly jumped back to 60% battery (makes me think it was absolutely not flat! )
