360 children's smart watch 3 How to take out the battery

Different models have different structures. If there is a screwdriver in the back, loosen it. Gently open the strap from the end with a flat and thin screwdriver. There is no screwdriver on the back.

Start at both ends of the strap, and then you can see four screwdrivers. If you loosen it, the back shell can be opened.
