I have buyed it three days ago and each night battery drains more or less a 20%.
For example, last night I went to bed with 34%, this morning it was only 15%.
Where are the 14 days of battery?.
Considering that I have also other issues, Activity rings don’t work and the poor support from CMF/Nothing, I am thinking to return it to Amazon.
Edit: This last night I activated Battery Safe mode with 30% of battery remaining and this morning the watch drains it all. Definitely it is something wrong with this unit, I charged again up to 70%, went for a walk for an hour with GPS active and it is still with 70%.
I definitely will return it to Amazon and maybe I will try again with a new unit instead of a warehouse unit as this one.
