In case your iPhone is not turning on, the problem could be due to both software and hardware related issues. You will find below some of the methods to fix an iPhone or iPad which is Not Turning ON.
iPhone Is Not Turning ON
In case your iPhone is not turning on due to software related issues, what is actually happening is that your iPhone is displaying a black screen due to a crashed software program.
In many cases, this problem can be fixed by hard resetting your device. If this does not help, you may have to go for a Factory Reset using iTunes or perform a DFU Restore.
In comparison, hardware related problems causing the iPhone not to start are difficult to fix and may require help from a certified technician.
1. Check For Physical Damage
If your iPhone is not Turning ON, perform a visual inspection of the iPhone and see if it has suffered any damage to the screen or the body.
If your iPhone is still under warranty and there is no evidence of physical or liquid damage, Apple should cover the cost of repairing your iPhone at no charge.
2. Charge iPhone
It is possible that your iPhone has lost all its charge. This can happen if the iPhone charger or the charging cable has become faulty.
Try to charge your iPhone for at least an hour by attaching it to a wall power outlet. You can try a different charger and charging cable, in case you have reason to believe that they may not be working properly.
3. Check For Water or Liquid Damage
While iPhones can resist shocks and survive after being dropped, they are very fragile when they are exposed to water.
1. Take a close look inside the SIM Tray opening of your iPhone. You should be able to see a white circular sticker. If the sticker is all white or silver, your iPhone is free from Liquid/Water damage.
2. In case you see a Red dot in the middle of the white sticker, it confirms that your iPhone has come into contact with Water.
If you see the Red dot, do not try to start or charge your iPhone. It can take up to 48 hours for the water to dry out. Unfortunately, water and liquid damage is not covered, unless you have Apple Care.
Note: If your device is wet, do not try to power it on. Powering ON a device while it is wet can cause serious internal damage to electrical components of iPhone.
4. Hard Reset iPhone
As mentioned above, it is possible that your iPhone is actually ON, but it is displaying a black screen due to software related problems. In most cases, this problem can be fixed by Hard Resetting iPhone.
The steps to Hard Reset iPhone depend on the model of your iPhone and the steps as provided below.
iPhone 6s and below: Press and hold both Power and Home buttons at the same time, until you see an Apple Logo appearing on the screen of your iPhone.

1. Connect your iPhone to computer using its supplied lighting to USB cable.
2. Open iTunes on your Computer and see if iTunes is able to recognize your iPhone. If your iPhone is appearing in iTunes, try to make a backup of your iPhone using iTunes.
