I've recently changed to a Fitbit Versa 2 after having a Huawei Android Wear for years until it literally fell apart. The Huawei never lasted more than a day, but I can get 2-3 with the Versa, which means I can use it for sleep tracking. Charging up only takes 30 minutes or so, so every few days I just pop it in for a bit. I ended up never using most of the features of the Android, so the Fitbit does me fine. The only thing I miss is the "now playing", but I can live with that.
