If the hair-cutting force of the clipper declines with its use, please refer to the following details:
1. Low battery: Try using a 5V/1A adapter that meets standards to recharge the clipper and see if the power issue persists;
2. Mode selection: The Xiaomi Hair Clipper 2 has two speed modes. When the powerful mode indicator is off, the clipper is in gentle mode, which provides less cutting force. You can switch to powerful mode by pressing and holding the power button;
3. Hair residue in the blade compartment: Hair residue can cause the blade to clog and affect cutting efficiency. Make sure to clean out any hair residue from the blade compartment regularly.
