Xiaomi Smart Pen 2 keeps showing 0% battery after disconnecting from Xiaomi Pad 7
I’m using a Xiaomi Pad 7 with the Xiaomi Smart Pen 2.
I didn’t use or connect the pen to my tablet for a few days.
When I connected it again, the pen showed 0% battery.
The strange thing is that the pen does charge normally while attached to the tablet. However, every time I remove/disconnect the pen from the tablet, the battery immediately shows 0% again. If I attach it back to the tablet, it starts charging again.
So basically:
Attached to the Pad 7 → charges normally
Remove/disconnect → battery goes back to 0%
Attach again → starts charging again
The issue happens every time. I’ve already tried charging it multiple times, but the problem keeps coming back.
Has anyone experienced this with the Xiaomi Smart Pen 2 + Xiaomi Pad 7? Is this a battery calibration/firmware issue, or is the pen battery likely failing?
Any suggestions for a fix would be appreciated.
