iPhone Won’t Turn On
The Problem: Your iPhone won’t turn on or it’s stuck on the logo screen.
The Fix: Try a force restart (anchor link). If that doesn’t work, try charging it for an hour – making sure you check that the USB cable and plug are working, as well as ensuring there’s no dust or debris in the phone’s charging port.
If it still won’t turn on, try taking it to an Apple store as it might be a hardware related issue, such as a completely failed battery.
