Can the battery be replase with longer lasting one

@kennethmil87767 there really are no larger capacity batteries for those. You may find some advertised but reality is, that you can only "squeeze" so much storage into that size of battery. If you find that the performance of your watch has decreased, and the battery just does not seem to last as long, check all of your settings and minimize others "apps" and uses. After that, you may need to consider a new battery, but there won't be much difference between a standard one and "high-capacity" advertised batteries (other than price).
