It is advisable to charge the watch for one day and one night.

The endurance is relatively strong. Check whether the charging port is in good contact.

It is suitable to simulate the durability test in R6 continuous GPS state. In an environment where you can receive GPS, start the running mode, and the power starts from 100% until the power runs out. R6 should be allowed to have about 4% power, the operation will stop automatically, and the watch time function can still be used. Test results: The continuous GPS battery life is also 16 hours and 48 minutes.

The GPS core chip of Yishun sports watch adopts the positioning IC made by Sony in Japan, which supports the three positioning systems of GPS+ Beidou +GLONASS and has the ability of fast positioning. In addition, Yi Zhun Watch integrates sensors from Philips, which can measure the dynamic heart rate every second, and the measurement accuracy is comparable to that of professional heart rate belt equipment, and it is not subject to any constraints, whether it is running, squatting, push-ups, yoga, badminton, etc. The intervention of dynamic optical heart rate chip can detect and warn potential risk factors in advance, help us to better monitor data and manage health, and provide scientific basis for making reasonable exercise plans.
