The battery percentage of my iPhone 12 jump to 10% in 1 minute. This bug happens multiple times.
The Battery Health 100%
After restart the iPhone, the number back to normal.
Is it a software bug or a hardware issue?

iPhone 12, iOS 17
Somethings clearly not right with the phone. I'm going to guess you didn't buy it from the Apple Refurbished Store? Buying a refurbished phone from other refurbisher's can be an issue. Can you return the phone for refund from whoever you bought it from?
How long have you owned this phone and have you had the battery replaced? I find it unusual that an iPhone 12, which was released in 2020, would still have 100% Battery Health at this point. On average battery health declines about 1% per month of ownership.
I just bought it as a refurbished iPhone.
Thanks. I am going to return it.
How do I fix my iPhone battery drain?
