The capacitor pen can be used for 3 days without charging. Long-term use of capacitive pen will certainly make the screen damaged, and even lead to failure, which is a very normal phenomenon. Because any electronic screen, such as a smart phone, or a handwritten computer notebook, touching the screen for a long time will cause the screen to fail and affect normal use. So the best way is to usually maintain more maintenance, regular inspection, update and refresh the software.
