1. The data on battery life was taken from testing conducted by the Huami Technology Laboratory using the following parameters: using factory default settings, receiving and displaying 50 message per day, having one alarm vibrate for 5 seconds, touching the button to display the time 10 times, spending 2 minutes on other operations, checking your measured heart rate 3 times, exercising for 1 hour per week (and activating the running function to monitor heart rate in real time and turning off heart rate notifications), and opening the Mi Fit App one a day to synchronize testing for data usage methods. During actual use, factors such as settings, operations, and the usage environment will have an impact on the battery life. These factors may cause results obtained during actual use to differ from lab data.
2. Data sources: IP rating of 5 ATM (equivalent to a water depth of 50 meters) is based on testing conducted by the National Quality Supervision Clock Inspection Center in accordance with GB/T 30106-2013, Report No. QT1803032. It can be worn in the shower, in the pool, or while swimming near the shore. It is not suitable, however, for saunas or diving.
