Why did my battery percentage go from 90% to 0?

[Android Central Question]

In my phone, my battery often goes from a high percentage to 0% suddenly.

When I plug it in, the battery charges up from 0%.

But, if I would wait for 1 or 2 hours, without charging the phone, and then restart the phone, the battery will go back to its original high percentage.

What is this happening?

It sounds like the battery is no beuno. Do you have a battery health function in your phone? What phone is it, and have you done any troubleshooting?
