Guys I need help. So my phone stuck on apple logo but when I plugged in charger, it became normal. So when I unplugged it started to restart itself and the apple logo started to show on my screen. It only happens when I unplugged my charger. Anyone know what is the problem. I tried using the same method as home and power button thing but it didnt work so please I need some help over here.

You should replace you battery.iPhone 6 Plus Battery

If it boots to home screen when plugged into a laptop, download 3utool an check the battery health

You’re stuck in the bootloop… The battery may have died, and is not being detected by the iPhone, which stops the device from booting all the way. If you have a laptop or desktop, download 3utool and check the battery health/state.
