I’ve had my Sony SWR10 Smart Band for some time now and it’s been great and so useful, especially the ‘Smart Wake Up’ alarm feature which I use all the time.
A couple of times I have run into an issue where the smart band stops tracking activity data including when asleep, which prevents the smart alarm feature from working.
I did contact Sony about this some time ago and arranged to return it for repair/replacement but I never got round to sending it off, a few weeks back I found it again and thought I would give it another go and surprisingly I found that it was working fine again so I started using it.
After about two weeks the same happened again and it stopped tracking activity data. After various troubleshooting methods I have worked out that the battery within it needs to be totally discharged to force it to turn off completely, then once recharged, it will work again just fine. There’s no easy way to discharge the battery sadly and it’s very much a waiting game, I tend to leave it for a week without using or charging it which in my case is usually enough to resolve the issue. It’s very much an inconvenience being stuck without it for such a long time when this happens but it’s the only way I know of.
This may not work in all situations but for me, it has worked perfectly 3 times now to resolve the issue of not tracking activity data.
