Long Standby: Powered by a 2300mAh polymer lithium battery and a deeply optimized energy-saving system to minimize the need for frequent charging. Operates as a standalone system, similar to a mini smartphone, and therefore does not support app connectivity. The package does not include a SIM card. Note: The watch uses the MTK6762 chip, which offers fast performance but higher power consumption. When the battery is completely depleted or when charging via a computer USB port, it may take 0 to 25 minutes for the charging icon to appear. Please wait patiently. It is recommended to use a charger with a voltage of 5V and a current of 1A or higher
