I’m running out of space on my iPhone and keep seeing mixed information about upgrading iPhone storage capacity. I’m not sure if a repair shop can safely replace the storage chip or if it’s better to use iCloud, offload apps, or buy a higher-capacity model. Has anyone tried this, and what were the risks, cost, or results?
The short answer is: you can’t upgrade an iPhone’s built-in storage after you buy it. Whatever capacity you picked is what the phone has.
There are repair videos and shops that claim they can swap the storage chip for a bigger one, but that’s not a normal upgrade. It means desoldering the memory chip, soldering in another one, and messing with firmware. That’s the kind of job where one small mistake can kill the phone completely. And even if it boots afterward, your warranty is gone, and Apple is very unlikely to help with that device later.
So the safer move is to clear out the space that’s already being wasted. A lot of iPhones have way more junk sitting around than people realize.
- Start with Settings > General > iPhone Storage. Don’t guess. That storage bar will show you what’s actually eating the space, usually photos, videos, apps, or Messages.
- If apps are taking up too much room, try Offload Unused Apps instead of deleting everything. It removes the app itself, but keeps the app’s documents and data. Later, if you tap the app again, it downloads back and your stuff should still be there.
- Check Messages too. Years of old group chats can hide a ridiculous amount of videos, GIFs, memes, and attachments. You can also set messages to delete automatically after 30 days or 1 year so it doesn’t keep building up forever.
- Photos and videos are usually the big one. Apple’s Duplicates folder helps a little, but it mostly catches exact copies. An app like Clever Cleaner can be more useful if your camera roll is full of near-identical shots. Its “Similars” tool looks for photos that are basically the same, picks a “Best Shot,” and lets you remove the extras together. The “Heavies” section is also worth checking because it sorts large videos by size. A few 500MB clips can burn through storage fast. It can also turn Live Photos into regular still images, which saves space if you don’t care about the motion part.
- If you’ve cleaned things up and still don’t have enough room, use cloud storage. iCloud is the easiest fit for an iPhone. With Optimize iPhone Storage turned on, your phone keeps smaller versions locally and stores the full-size photos and videos in iCloud. You still see them in Photos, but they take up much less room on the device. If you don’t want to pay for iCloud, Google Drive gives you 15GB free, and Dropbox has a free tier too, though you’ll have to manage uploads and files more manually.
- External storage is another option people forget about. There are flash drives made to plug straight into an iPhone, Lightning for older models and USB-C for iPhone 15, 16, and 17. Some can even record video directly to the drive, so the file never fills your internal storage first. Just make sure the drive is formatted in a supported format like exFAT or APFS.
It’s annoying that you have to manage it this way, but it’s still a lot safer than gambling on a hardware storage swap.

The sneaky downside with iCloud Photos is that it’s sync, not a separate backup, so if you delete photos from the phone to “make space,” they can disappear from iCloud too. I agree with avoiding storage-chip swaps, but before any cleanup spree, copy the important stuff to a computer or external drive first.
Expect the “upgrade” route to cost more in stress than it saves in storage. Even if a shop can do the NAND swap, you’re trusting them with the whole phone and your data, and future iOS updates or repairs can get weird. Before paying anyone, I’d do a full encrypted backup to a computer, erase the phone, then restore it, because sometimes the mystery “System Data” bloat shrinks a lot after that. It’s not a magic fix and it won’t turn 64GB into 256GB, but it’s cheaper than surgery and less annoying than finding out the repair guy turned your iPhone into a paperweight.
