One of the biggest complaints with smartwatches is the need to recharge them as often as a smartphone. The best smartwatches you can get typically don’t last longer than two days, and most require daily charging. The new Amazfit Bip, which is available in the US starting today, provides up to a promised 45 days of battery life, putting even the venerable Pebble (RIP) to shame.

The Bip is not a hybrid watch or a stripped down device, either: it has a 1.28-inch touchscreen display, an optical heart rate sensor, true GPS for location tracking, a 3-axis accelerometer, IP68-rated water resistance, and notification support from both Android and iOS devices. The company says that the watch can reach 30 days on a single charge, and up to 45 days with “minimal notifications.”
