If you’re in the market for a fitness tracker, you’re more than likely hoping to modify your health behavior — whether it’s remembering to walk more, tracking how often you work out or making sure you’re working out appropriately hard when you do. The wearable market is saturated with options, but you won’t find one that’s much more affordable than Xiaomi’s latest Mi Band 4. It’s packed with features for half the price of counterparts from Fitbit and Garmin. There’s a lot to like about the Mi Band 4. For $40, you get a fitness tracker that has waterproofing, a heart rate monitor, workout tracking, text and call notifications, sleep tracking, and an impressive battery life of up to three full weeks, depending on usage. Compared to the monochrome Mi Band 3, version 4 has a 0.95-inch full-color OLED touchscreen with a 400-nit peak brightness. The screen is colorful and vivid, responding quickly to up and down swipes to browse through menu options for music control, alarms, workout tracking modes, or settings. The raise to wake the screen option wasn’t always successful, but I do like that it allows you to only turn this feature on between certain hours of the day so it doesn’t suddenly turn on while you’re tossing and turning in bed.
