Android phone question

[SHRED]

My Galaxy S8 all of the sudden shows 3% battery charge.
I shut it off, plug in the charge cable, and 10 minutes later it shows 100%.

It'll also show 100% for too long during use.

What's happening?

Going to Device care in the settings. After it runs click the battery setting at the bottom to see if you see anything unusual.

I have an S8, but haven't seen your issue.

It's free. You may have stuck cells and this will fix it.
