Iphone not turning on

Leave the charger connected to the iPhone for at least 2-3 hours and then check again. If the battery is charging, leave the charger connected and fully charge the battery up to 100%.

Of course, here we are assuming that the charger and cable are working correctly. Good idea to try another charger and cable if available.

If the battery simply will not charge, it is defective and will need to be replaced at the Apple Store / Genius Bar or an Authorized Apple Service Provider (AASP).

Did your iPhone "die" because the battery went to zero, or were things running normally and the iPhone suddenly lost power?

Have you tried another power supply and cable?

If a Forced Restart does not help, that indicates that there is a hardware issue on the iPhone that will require attention at the Apple Store / Genius Bar or an Authorized Apple Service Shop (AASP).
