How to spot wear on an Apple Pencil tip
A rough or jagged tip, extra friction, exposed metal or lost connectivity may signal that an Apple Pencil tip needs replacing, according to Engadget.

Apple Pencil tips wear with use, and Engadget’s guide lists several signs to watch for: a tip that has become jagged or rough, more friction while writing or drawing, and declining connectivity.
Visible metal beneath the tip is a clear sign to replace it, Engadget says. Replacing a worn tip before then may also help avoid scratching the screen.
Engadget gives about two years as a general replacement estimate, with heavy users potentially needing a new tip in less than a year. Actual wear depends on use.
Apple sells replacement tips in four-packs for $19, according to Engadget. The guide also notes third-party options from brands including PenTips and Delidigi, which market tips for different drawing and writing feels.
