Part 1: Why Is My New iPhone 15/14 Not Turning On?

Only when you get a full picture of why the iPhone 15 or iPhone 14 won't turn on can you find the appropriate solution. So, before getting started, let's explore some possible reasons behind it:

1: Battery Depletion – It is possible that the new iPhone has run out of power, leading to an unresponsive iPhone screen.

2: Damaged Charging Cable and Adapter – Sometimes the problem is with the charging accessory, not the iPhone itself.

3: System Bugs and Glitches – It is not uncommon that an iPhone won't turn on in the event of an iOS system failure, especially after updating iOS, which prevents the iPhone from booting.

4: Jailbreak Failure – If you haven't succeeded in jailbreaking a device, it can cause a black or frozen screen.

5: Hardware Damage – Besides software factors, hardware factors need to be considered, including water damage, battery problems, and malfunctioning buttons, among others.

Part 2: How to Fix iPhone 15/14 Won't Turn?

Based on the previously mentioned causes, this section will show you how to fix that the iPhone won't turn on issue.

Solution 1: Force Restart iPhone

Try force restarting your iPhone 15/14 by following these steps:

• 1: Press and quickly release the Volume Up button.
• 2: Press and quickly release the Volume Down button.
• 3: keep holding the Side button until the Apple logo appears (this takes around 10 seconds).

Solution 2: Fix iPhone Won't Turn on by Charging iPhone

If a force restart does not resolve the issue, it is possible that the iPhone may have completely run out of battery or encountered a more serious problem. In such cases, try connecting it to a power source and allow it to charge for a while before attempting to power it on again.

After charging for a few minutes, you should see a red battery icon displayed on the screen, indicating that a low battery is preventing the iPhone from turning on.

Solution 3: Check Device Hardware and Accessories

What if the battery icon does not appear on the screen? If this happens, you need to check if the charging cable or adapter is damaged. For example, charge your iPhone with another power source and if the screen remains black, replace the charging cable and adapter with new ones. However, if the problem persists even with new accessories, it is necessary to delve into potential hardware issues.
