I have used the watch of Withings / Nokia for four weeks now and some of my experiences I share in this video. Especially this week it also causes some problems, the change into Nokia.....
About battery: After full charge I used it 24 days and watch shows me then 'low battery'.

The fog-issue is probably common and I have contacted Nokia by e-mail and eventually I have a good agreement. I will get a new watch when the new Nokia HR Steel is presented. And as comfort I got a Nokia Body for free. So they have a good service. Also the issues with problems with the app are merely fixed now.
