Only works via Bluetooth, the cable is only for charging.

The mouse usually connects directly via Bluetooth. If there are other connections such as a wireless keyboard and wireless mouse, I would unplug the wireless mouse. Depending on the PC, it is possible that if a Bluetooth headset is also used, jerky bottlenecks may occur. As a rule, however, these were very rare for me. It could also be that two devices are interfering with each other, in which case it would be advisable to pair the mouse again via Bluetooth.
