It's got a 5ATM waterproof rating, which means it's safe for showering and a swim up to 50 meters' depth. For sleep, you're getting some pretty comprehensive data and insights. You can't view sleep data on the Band, so it's over to the app to see how well or badly you've slept.

For activities like running, pool swimming, indoor rowing, core metrics are on the whole reliable. Both devices are better suited to 20-30 minute workout time as opposed to running or cycling for hours if you crave optimum accuracy. You will of course get a bigger display on the Mi Band 6 to fit in more information on single screens and to make the watch faces at your disposal look a little nicer.

What should a sports strap have

The radio waves generated by the equipment may affect the normal operation of implanted medical equipment or personal medical equipment, such as pacemakers and hearing aids. If you use these devices, please consult their manufacturers for restrictions on using this device. Heavy usage scenario: Heart rate monitoring is always on and measures at 1-minute intervals, high-precision sleep and all-day stress monitoring are enabled; 200 pushed messages a day; receive 15 call notifications per day, vibrations last for 10 seconds each time; raise wrist to see device time 500 times; sync with the Zepp App once per day; test blood-oxygen 2 times per day; exercise data is recorded for 90 minutes per week. You're also getting those SpO2 readings carried out by the same sensor that delivers the heart rate data. We tested it against a dedicated pulse oximeter and found that readings were identical. The star here is the screen. It's a high quality AMOLED screen that's colorful, bright, vibrant and is superior to screens that cost more (we're looking at you Fitbit).

This product and the Zepp App are not medical devices and cannot be used for medical purposes, or as basis for diagnosis of any medical condition. Detection results are provided for reference only. Please consult professional medical institutions if you feel unwell. This feature is only supported by Android devices with Zepp App version 6.10.0 or higher version installed. Power Saving GPS Mode: Turn on heart rate monitoring and GPS exercise (single frequency, GPS low power consumption).

The straps of the Xiaomi Mi Band 5 are compatible

To get closer to double digit days of battery life, you're going to need to disable things like the sleep assistant, 24/7 heart rate monitoring and not keep the screen at max brightness. For the Mi Band 6, you're getting something with a similar sized polycarbonate case and plastic strap combo with the same style pin clasp that we can't say we absolutely love. That houses a larger 1.56-inch, 152 x 486 resolution AMOLED display. You're getting the same water resistant rating as the Amazfit Band 5 here too.
