Why does the battery run out so quickly
Usually, the battery will last 3-7 days, but the standby time will be different under different conditions. For example, it will be reduced if you often use Sport Mode or tap the screen from time to time. If you want the device to run longer, please go to the APP page to turn off a few of the functions that you seldom use
Why the fitness tracker always reset
Please note that the fitness tracker will reset under the following situations: 1) The watch steps will reset when a new day begins; 2) The bracelet will be off automatically if there is no power, and it will be on once you put it to charge, then the time will reset. So you need to connect the watch with your phone again to sync the time.
Can I use the seperately without connecting the phone
It has to be connected with a smart phone by the application "BIGGERFIVE" before initial use. Because the date and time of the fitness tracker can only changed by connecting with a smart phone. After connected with a smart phone once, it can used alone to check the steps, calories, heart rate, moving distance, and active minutes. The activity data can be showed on the display of the fitness tracker. But for the information of sleep quality, it only records in the application.
Is it water proof
Yes, it is waterproof. It supports sweat-proof, rain-proof and splashed water proof etc. It is no problem to wash you hands or doing some washing/cooking by wearing it. But it can not be kept under the water for a long time, so we would not recommend you to swim with it. And for any wearable devices, it will be better for its using life to keep it dry and clean.
