I have swam with my Fitbit charge 5 on many occasions before and it has been fine. Swam in Spain (in a Poole) last week and it just stopped working mid way through. Left it for a couple of days and put it on to charge and it charged fine. It then kept loosing charge very quickly, which I thought might be something to do with the hot weather…. Since I got home yesterday I charged it yesterday evening to 100%, by this morning it was down to 30%. I charged it for 30 minutes and got it up to 50% from 14. I then had to charge it again in the afternoon it was a full charge around 4.00pm and had already dropped to 76 at nearly 6.30pm
