As an ornament for human beings, in recent years, major manufacturers have launched smart bracelets. From the initial step counting, call prompt, alarm clock, etc., they have gradually evolved into heart rate testing, which can be used as a watch, increase heart rate testing, and increase the display screen. From the initial thousands of dollars to hundreds of dollars, you may spend tens of dollars on a treasure to buy a smart bracelet, There are so many manufacturers, but even Apple has not been able to do a good job in terms of the endurance of the bracelet. How to make a bracelet with a large screen and strong endurance has always puzzled the major bracelet manufacturers.

Xiao Bian has also used many bracelets, Xiaomi bracelet, Tuman second-generation bracelet, The fii watch bracelet, except for the Xiaomi bracelet, is not enough in endurance. I have to say that the bracelet without a screen has a high endurance. Recently, Xiaobian was lucky to get the trial of the i7 intelligent heart rate bracelet on the Lei Feng trial website. Except for the basic screen, the endurance is 7 days when the heart rate is turned on, and 20 days when the heart rate is not turned on, In terms of endurance, it can be said that it is comparable to the Xiaomi bracelet.

Heart rate test:

In fact, there is no good software for heart rate testing, but the Xiaomi bracelet light sensing version is edited and the Evi i7 smart heart rate bracelet is used for heart rate testing at the same time. The Evi i7 smart heart rate bracelet is 56 and the Xiaomi bracelet light sensing version is 65.

Waterproof test:

The waterproof grade of Evian i7 intelligent heart rate bracelet is IP65, which belongs to life waterproof. However, the surface of the metal body personally feels that the general life waterproof is to remove the handle in the case of bathing and swimming. The small knitting machine uses a shower to test and place it for five minutes, then wipe it dry and use it to reach the waterproof grade.

By downloading the official APP, binding the bracelet, pairing, etc., the bracelet can be controlled normally through the mobile phone APP. It is worth noting that the i7 smart heart rate bracelet can provide information support such as steps through Apple's built-in health software.
