Why does my iPhone 8 Plus keep flashing the Apple logo?

My old iPhone 8 Plus doesn’t turn on when it’s not charged. when it is plugged in, it doesn’t turn on normally and it just flashes the Apple Logo on the screen on and off again. I’ve tried everything, forced reset, letting it charge, unplugging it, nothing. It just keeps flashing the same apple logo every time when I charge it.

Your battery has reached the end of its life, time to replace it.

Batteries degrade over time with usage due to chemical aging, that's just how they work.

You can expect about a 1% drop per month with average use on an iPhone. This is an approximation, that is why it may be plus or minus a few percent on a month to month basis.

Apple recommends replacing it when it reaches 80%. To check your battery health, go to Settings > Battery > Battery Health.
