iPhone 8 turns off abruptly

  1. Fully charged, unplugged and then abruptly turn off within 2 minutes while using. Can't turn on unless plug in charger. Updated to iOS 14.5.1. Already tried reset, and restored using Mac. Battery health 80%.
  2. This above is the latest issue in my phone, besides other issues since I purchased in 2018; screen turn off while using, can unlock screen without needing finger print sometimes.

I already checked Serial Number several times for replacement program and it says not eligible.

Here is the link that you requested iPhone Battery and Performance. Ensure that you read through the whole and thing and I would like to draw your attention to the Your battery's maximum capacity section. There is also a section on Preventing Unexpected Shutdowns.
