Amazefit Bip - pro: transflective display with backlight, supreme battery life (weeks), virtually indistructible (although I had massive doubts at the start), all the features I need. con: replaced the wristband almost immediately - really cheap.
MrrdrrBip here. Bought 2018. Have been charging it literally only once a month.
It relieved me from the battery anxiety of my previous sony smartwatch that ran the full googles smartwatch OS. That thing lasted usually a day. Less if i did anything meaningful on it. It made me seriously think if it needed a watch that would do everything, but ended up doing nothing anyway because of the battery life.
unomarExactly this. It’s nice to go on vacation and not even worry about packing a charger.
