David Porter <time itemprop="datePublished" datetime="2020-12-13 09:25:14Z">12/13/2020 9:25 AM</time> Got one of these given to me. Battery is garbage. Hope I can get it replaced. Otherwise its amazing
Construction King <time itemprop="datePublished" datetime="2021-05-09 17:46:54Z">5/9/2021 5:46 PM</time> If you choose a watch face that is basic and not using GPS and data a bunch I can get 4 days out of a charge. If I use it a lot It still lasts a full day. I bought a good wireless charger for mine, I get full charge in around an hour. I've Han my 805u for about 2 yrs. LOVE IT!!! Never has stopped working. Bought it used.
