Xiaomi graphics tablets — like the Xiaomi Pad 6, Pad 5 Pro or Mi Pad 4 — have long ceased to be just devices for viewing content. 2nd Gen, they're now tools for artists, designers and students, but even the most advanced pen is useless when it's discharged. And that's where the questions start: how do you charge the pen properly? Can you charge the tablet and the stylus at the same time? Why doesn't the pen hold the charge? In this article, we will analyze all the nuances - from basic instructions to solving common problems.
It's important to understand that charging a graphic pen is different than charging a tablet. If it's simple with a tablet, plugging a cable into a power bank, the stylus has its own intricacies: special connectors, magnetic mounts, and even the risk of damaging contacts if you handle it sloppy, and some Xiaomi feather models support wireless charging right on the tablet case, while others require a separate cable. We'll go through each case in detail.
This article will be useful not only for beginners, but also for advanced users. For example, did you know that the Xiaomi Smart Pen 2 pen can be charged up to 100% in just 60 minutes, but its battery will last longer if you do not maximize the charge? Or that some cases block the magnetic mount of the pen, which causes it to not charge? These and other life hacks you will find below.
Types of Xiaomi styluses and their charging features
Before you talk about charging, you need to understand what kind of pen you're holding. Xiaomi has several generations of styluses, and each has its own charging method:
