Simple Fixes If iPhone Still Won’t Turn On(No data Loss)
Simple Fix– Solution 1:Charge Your iPhone Properly(Do Not Skip)
Charging your iPhone is the simplest way to fix an iPhone wonot turn on. Using a reliable charger and allowing 15–30 minutes of charging helps restore stable power and enables the system to turn on normally.
Note: If the iPhone still shows no response after 30 minutes of charging, try a different cable, adapter, or power source to rule out charging accessory issues.
Simple Fix– Solution 2: Force Restart(Most Effective Fix)
A force restart also works for an iPhone that won’t turn on; it is a free way to turn your iPhone on again without data loss.
For iPhone 17 / 16 / 15 / 14 and newer models to force restart：
Step1. Quickly press and release Volume Up

If your iPhone shuts off after Gaming or charging in the heat， letting an overheated iPhone cool down is a good way to fix an iPhone wonot turn on, because iOS automatically shuts the device off to prevent damage.

Advanced Fix – Solution 5:Use iPhone Recovery Mode （Data will be lost)
Recovery Mode can fix an iPhone that won’t turn on because it allows iTunes or Finder to reinstall or repair iOS when the system fails to boot normally, resolving severe software crashes that block startup.
How to Fix an iPhone that won’t turn on with iPhone Recovery Mode?
Step 1: Connect your iPhone to a computer using a USB cable and open Finder (Mac) or iTunes (Windows).
Step 2: Put your iPhone into Recovery Mode using the correct button combination for your model. When prompted, choose Update to reinstall iOS without erasing data.
Step 3: Wait for the system download and installation to complete. Once finished, your iPhone will restart and should turn on normally.
Note: Using iPhone Recovery Mode risks data loss if you select Restore instead of Update, as Restore erases all content on the device.
Advanced Fix– Solution 6: Enter iPhone DFU Mode (Data will be lost)
Use DFU Mode only if Recovery Mode fails. DFU Mode can fix an iPhone that won’t turn on because it completely reloads the firmware and iOS system, bypassing the normal boot process and resolving deep system corruption that prevents the device from starting.
Steps to fix iPhone won’t turn on with iPhone DFU mode:
Step 1: Connect your iPhone to a computer and open Finder (Mac) or iTunes (Windows).
Step 2: Put your iPhone into DFU Mode using the correct button combination for your model. The screen should stay black. When your computer detects the iPhone, choose Restore iPhone.
Step 3: Wait for the firmware and iOS installation to complete. After the process finishes, set up your iPhone and check if it turns on normally.
Note: Entering DFU Mode will erase all data on your iPhone and should be used only as a last resort. Make sure your device is sufficiently charged and connected to a stable computer, as interrupting the process may cause additional system issues.
Final Fix – Solution 7: Seek Professional Help for Hardware Repair
If your iPhone still won’t turn on after trying all software-based solutions, the issue is likely hardware-related—such as a damaged battery, charging port, logic board, or internal components. In this case, seek assistance from Apple Support or an authorized repair center for proper diagnosis and repair. Professional hardware service is the safest and most effective option when software fixes no longer work.
You likely need professional repair if:
- iPhone shows no response when charging
- The device overheats immediately
- Visible water or impact damage exists
Note: Before seeking hardware repair, make sure you have tried all software solutions and, if possible, backed up your data.
