Mi Band 4 Display
The Mi Band 4 has AMOLED 2.5 D display it’s pretty much the biggest upgrade. We get really punchy colors with a pre brightness of 400 nits so outdoor visibility even in direct sunlight is very good. It wasn’t a problem we get an option in the settings’ menu on the band itself to increase or decrease the brightness.
Jumping to back to prose, despite the relatively small screen size the touch response here was great. We didn’t face any missed ABS all the taps and swipes work flawlessly good job. Honestly, the display here is pretty good. And during our testing, we had almost all features turned on except idle alert the heart rate sensor had been set to monitor every 30 minutes. With all this, we still managed to get about 10 days on a single charge. Now yes, Xiaomi does promise up to 20 days, but they do say up to and if you aren’t really monitoring your heart rate every 30 minutes. If you don’t have all these features turned on which most people might not you should get better battery life.
The Mi Band 4 is rated to resist up to 5 ATM of water. Which basically means that Xiaomi says you can go swimming with it in case you walk out of range. The band shows up with a Bluetooth icon which means it is disconnected from the phone. You cannot take calls on the band. But you can mute or reject calls using the touch screen. In case you lose your phone, you can find it using to find my phone feature.
