Setting up a new iPhone can be annoying, and it's not because there's something wrong while setting up a new one. But moving data from one iPhone to another can be a bothersome process - especially if users have a lot of data in their previous phone. Then there's the hassle of reinstalling apps, and all the other essentials users might have on their previous devices.

However, this gets even more irritating when users face the issue that the iPhone won't transfer to the new iPhone because of not enough space. But that doesn't mean there's no fix for this issue because that's what this article will demonstrate. Let's dive right into it and explore some of the best solutions for this problem.

What to do When Not Enough Space to Transfer Data?

There are numerous ways to tackle this issue, and all of these solutions require one to do a few things. This section will show users four of the best methods to fix this problem in iPhones today. So let's explore the four primary techniques users can try to fix if their iPhone won't transfer to a new iPhone.

Fix Effectiveness Speed Difficulty
1️⃣iPhone Storage Cleaning Probable Slow High
2️⃣Managing Photos & Videos Guaranteed Rapid Very Easy
3️⃣Removing Unused Apps Highly Likely Slow High
4️⃣Resetting iPhone Guaranteed Very Quick High
5️⃣EaseUS MobiMover Guaranteed Rapid Very Easy
6️⃣iTunes/iCloud Highly Likely Slowest Moderate

Fix 1. Check iPhone Storage

The first thing users should do is check their iPhone's storage. It's possible that the new iPhone doesn't have enough storage to accumulate the data from the previous iPhone. The files won't transfer if data from the preceding iPhone is 80+GB and the new iPhone only has 64GB storage.

Here's what the users should do to check that's not the case:

Step 1. Head into Settings.

Step 2. Then open General and find the iPhone Storage option.

Step 3. Check the storage situation.

It's not the storage issue if there's ample storage available in the new iPhone. Then it's likely something else is causing the issue, so move on to the next fix.

Fix 2. Manage iPhone Photos and Videos

Users may have too many photos and videos that prevent that transfer on their iPhones. Therefore, it's essential to manage iPhone photos and videos. But that process can be full of hassle unless you use a proper third-party iPhone data management tool, EaseUS MobiMover, one of the best iPhone users can try.


With it, you can do the following to manage your iOS content easily:

Fix 3. Remove Unused Software

There are many apps on iPhones that take up a lot of space. They don't only take space of their own, but their junk data and downloaded files occupy a lot of storage in iPhones too. Uninstalling these unused software/apps will also free up space, and here's how to do that:

Step 1. Tap and hold the icon of an unused app.

Step 2. Select the Remove App option.

Step 3. Confirm by tapping on the Delete App prompt.

Repeat this method until there are no more unwanted or unused apps on the iPhone.

Fix 4. Reset New iPhone

Resetting the new iPhone might also fix iPhone not having enough space issue to continue the iPhone transfer from the previous one. There are times when secondhand iPhones download files from previous iCloud backups. That's why users aren't able to use the storage freely and transfer new data.

To avoid that, it's essential to factory reset iPhone and free up some space. Here are the steps that iPhone users should take carefully to reset the new iPhone:

Step 1. Head into Settings > General > Transfer or Reset iPhone option at the bottom.

Step 2. Now select Erase All Content and Settings option.

iPhone Won't Transfer to New iPhone Not Enough Space FAQs

Here are some FAQs that'll help users a bit more with this issue:

1. Can you transfer to an iPhone with less storage?

There are cases when this is possible. Let's say an old iPhone with 128GB storage only used 30GB for data. Then a user will be able to transfer all their files to a 64GB iPhone as 30GB will take only around 50% of the storage in the new iPhone.

2. Why is my iPhone saying I had no storage when I bought storage?

Apple's iPhone has physical storage like all phones. So, users are buying online storage when they buy more storage. That means it won't replace or expand their existing storage; it'll just help them get more space on iCloud. The only way to gain more space in the iPhone will be by uploading these images or videos to iCloud or by deleting unused apps.

3. Why won't my data transfer from the old iPhone to the new iPhone?

There are a few problems that might thwart old iPhone data from transferring into the new one. The most palpable and usual reason behind this is when a new iPhone doesn't have enough space to house the old iPhone's data.

Then, it could be a minor glitch that could be fixed by simply restarting both iPhones. If none of this works, then users should try alternative methods of transferring, like using a third-party transfer tool like EaseUS MobiMover.
