How to connect to bluetooth? I tried to connect via phone setting but failed.

Hello, attached is a video to show you the detailed steps. If you still can't connect it to your phone, please let us know the OS and model of your phone so that we might check your issue further. Any further questions, feel free to contact us.

Can i get instant results after pressing test?

Hello, please wait a few seconds after pressing the Test button, and the corresponding Battery Voltage Indicator (FULL / MEDIUM / LOW) and Battery Health Indicator (GOOD / MEDIUM / BAD) will light up to show the test result. Please note that once the Bluetooth is connected, the Test Button on the battery tester will no longer work. In this case, you can only test batteries via the APP.
