Chosen Solution
So I recently got a iPhone 8 plus from a family member free as they got a new phone.
Today ive tried just about everything from resetting it to charging it for 3+ hours but nothing happens. the home button is unresponsive and so is doing anything else with this phone..
Could it be the battery just needs to be replaced?
Hard to tell if a new battery will be all that’s needed, but that’s certainly the first step to be tried. iPhone 8 Plus Battery Replacement
First ask your family member if they were having any problems with it. Getting a history on a device can help solve a plethora of issues.
