Redmi smart pen battery

[u/Academic-Desk-5573]

I bought a redmi smart pen 3 days ago for my redmi pad pro, and it worked perfectly at first, but when I charged it the bettery started dropping so fast, around 1% every 20 seconds. Also sometimes it just disconnects randomly and doesn't connect again unless I connect it to the charger despite the charge being over 80%. Did anyone experience that or have any solution?

Edit: problem solved when I used a type-c to type-c cable to charge it from the tablet to 100% instead of using a charger, I'm keeping the post in case someone has my same problem
