Unable to Move Data from Your Previous iPhone to iPhone 16/15? 10 Handy Fixes!

So, what could be hindering the data transfer process between your iPhones? To me, it’s the sluggish internet connection that tends to either slow down the data migration process or interrupt it frequently. Therefore, we will first look for ways to fix the ill-functioning interment connection. That aside, there are other usual suspects which we will take into account in order to resolve the problem.

1. Make Sure to Place Your Old iPhone and iPhone 16/15 Close Together 

To begin with, be sure to keep both your old iPhone and the new one close together. As this is a must-have requirement, make sure to check it off without fail.

2. Ensure That Both Bluetooth and Wi-Fi Are Enabled 

Another must-have requirement that you need to keep in mind is that the “Quick Transfer” process requires your iPhone to have both Wi-Fi and Bluetooth enabled. Head into the Settings app -> Wi-Fi/Bluetooth and ensure that they are enabled. 

After that, go through the on-screen instructions to complete the data transfer process. If you don’t see the prompt to set up the new iPhone or if the prompt goes away, you will need to restart both iPhones.

Bear in mind that if your iPhone 15 is enrolled in Apple School Manager or Apple Business Manager, you won’t be allowed to use Quick Start to transfer data from your previous device.

3. Turn Off/ON Airplane Mode

If your Wi-Fi or cellular connection is below par, it could be preventing the data transfer process.

  • On your iPhone, swipe down from the top right corner of the screen > tap on the airplane mode icon to turn it on/off.

4. Hard Reset Your iPhone

If a minor software glitch is behind the problem, force restart could come in handy in troubleshooting it.

  • On your previous iPhone, press and release the volume up button > Next, press the volume down button and release it. 
  • After that, be sure to hold down the Side button until you see the Apple logo on the screen. 

5. Disable Low Data Mode on Your Old iPhone

“Low Power Mode” aka built-in power-saving mode is designed to help your iPhone boost the battery life by either pausing all the power-hungry features including background activity like downloads or completely turning them off. If this power-hungry feature is enabled, it could be throttling the data transfer process between your iPhones.

  • Navigate to the Settings app on your iPhone -> Battery -> turn off the toggle next to Low Power Mode.

6. Keep Both Your iPhones Plugged Into a Power Source

Even if your iPhones have sufficient power, I would recommend you connect them to a power source. It helps devices deliver peak performance, which would help speed up the data migration process.

7. Enable Wi-Fi Assist 

Wi-Fi Assist prevents unwanted interruptions by allowing your iPhone to seamlessly switch to mobile data when the Wi-Fi connection is poor. 

  • Head over to the Settings app on your iPhone -> Cellular -> Scroll down to the bottom of the screen of the screen and then turn on the toggle next to Wi-Fi Assist.

8. Allow More Data on 5G

If you have enough cellular data, why not allow your iPhone to make the best use of 5G? Slightly hidden inside the cellular settings exists an option to allow more data on 5G, which comes in handy during software updates, automatic iCloud backups, and other power-intensive tasks. 

  • On your old iPhone, go to the Settings app -> Cellular -> Cellular Data Options -> Data Mode -> Allow More Data on 5G.

9. Reset Network Settings 

If you haven’t been able to fix the data transfer issue, reset the network settings. 

  • On your iPhone, go to the Settings app -> General -> Transfer or Reset iPhone -> Reset -> Reset Network Settings -> enter your device passcode and confirm.

10. Exercise Some Patience While Your Data is Being Transferred 

It’s important to point out that if you choose to download your data from iCloud, your apps and data will effortlessly be downloaded in the background. Thus, you can start using your new iPhone without having to wait for the download process to complete.

But if you decide to transfer your data directly from your previous iPhone to the iPhone 15, you will have to wait for the data transfer to complete on both devices. While the data is being directly transferred to the new iPhone, you can’t use your devices.

Talking about the transfer times, they can vary depending on many factors such as the amount of data being transferred and your network speed. Therefore, sit tightly while the “Quick Start” is in action and allow the whole process to complete without any obstruction at all.

There you go! I hope you have successfully migrated your data from the previous iPhone to the new one. Feel free to share your feedback and the tip that has come to your rescue.
