Galaxy watch 4

I decided to charge my Galaxy watch 4 today and I put it on just before I went to work and it was at full charge, by the time I took the photo at time shown you can see it's gone down to 40%.

I decided to back to my cheaper watch and the battery will last nearly 2 weeks before charging and it's an Amazfit (Chinese) but it's a very good watch and does nearly all that the Galaxy watch does.
