When the smart jewelry is connected to the phone through the app, the phone needs to constantly communicate with the jewelry to ensure its normal use. Therefore, relevant permissions need to be enabled in the settings, and the app needs to be kept running in the background. This may increase the power consumption of the phone, but not by much. The power consumption is similar to that of other apps under normal circumstances. If you still think that the power consumption is too fast, you can consider closing the app and turning off background location and Bluetooth permissions when not using the jewelry. You can then open them again when needed.
