Disabling stylus to prevent worn tip performance degradation and screen damage

A method comprising:

• tracking a parameter representative of an amount of tip wear of a tip portion of an active stylus, the parameter updated based on an input received from the active stylus;
• in accordance with a determination that the parameter does not exceed a first threshold, performing an action associated with the input from the active stylus;
• and
• in accordance with a determination that the parameter exceeds the first threshold, rejecting the input from the active stylus.

A non-transitory computer readable storage medium storing instructions, which when executed by a processor, cause the processor to:

• track a parameter representative of an amount of tip wear of a tip portion of an active stylus, the parameter updated based on an input received from the active stylus;
• in accordance with a determination that the parameter does not exceed a first threshold, perform an action associated with the input from the active stylus;
• and
• in accordance with a determination that the parameter exceeds the first threshold, reject the input from the active stylus.

An electronic device for use with a stylus comprising:

• a touch screen;
• and
• a processor coupled to the touch screen and capable of:
• estimating a level of wear of a stylus tip;
• and
• in accordance with a determination that the level of wear of the stylus tip exceeds a first threshold, disabling stylus input functionality of the electronic device.
