You're trying to take a video of your kid's first steps or maybe just a shot of a really good taco, and there it is. That annoying "Storage Almost Full" popup. It’s the digital equivalent of stubbing your toe. Most people think they have to go on a scorched-earth mission, deleting every photo from 2022 just to breathe. Honestly? You probably don't. Knowing how to make space on my iPhone isn't about getting rid of memories; it's about clearing out the "digital exhaust" that Apple hides in the corners of iOS.
Let's be real. iPhones are basically high-end cameras that happen to make phone calls. High-resolution photos and 4K video clips eat gigabytes for breakfast. If you've got a 128GB model, you're living on the edge. Even the 256GB versions fill up faster than you’d expect once you start downloading Netflix episodes for a flight or hoarding "Maybe" shots in your camera roll.

The "Other" storage mystery and why your phone lied to you
Ever looked at that colorful bar in your settings and seen a massive gray chunk labeled "System Data" or "Other"? It’s frustrating. This is where your iPhone stores caches, logs, and temporary resources that the system thinks it needs. It’s not just one thing. It's a mess of Safari history, Siri voices, and streaming buffers.
To see the damage, go to Settings, then General, and tap iPhone Storage. Wait for it to load. It takes a minute because the phone has to index every single file. You’ll likely see "Photos" or "Messages" at the top, but scroll all the way to the bottom. If "System Data" is over 10GB or 15GB, your phone is being a packrat.
One of the weirdest but most effective ways to shrink this is simply to plug your phone into a computer and open iTunes (on Windows) or Finder (on Mac). You don't even have to sync it. Just letting the computer "handshake" with the iPhone often triggers a cleanup script where the phone realizes it doesn't need those temporary cache files anymore. It’s like the phone tidies up because company is coming over.
Offloading: The genius feature nobody uses
If you’re wondering how to make space on my iPhone without losing your game progress or app settings, "Offload Unused Apps" is your best friend. There is a huge difference between deleting an app and offloading it. Deleting wipes everything. Offloading removes the app’s "brain" (the heavy code) but keeps the "soul" (your data and documents).
Go to Settings > General > iPhone Storage. You can enable this automatically. When your space gets tight, iOS will quietly remove that airline app you used once six months ago. The icon stays on your home screen with a little cloud symbol. When you need it again, tap it, it redownloads, and your login info is still there. It’s seamless.
The hidden weight of your Messages app
We talk a lot about photos, but "Messages" is often the secret storage killer. Think about every meme, Every video, and every "Live Photo" your friends have sent you over the last three years. If you’ve never changed your settings, your iPhone is likely keeping every single one of them forever.

- Go to Settings.
- Tap Messages.
- Look for "Keep Messages."
- If it's set to "Forever," change it to "1 Year" or even "30 Days" if you’re brave.
The moment you toggle this, your iPhone will ask if you want to delete older messages. Doing this can instantly reclaim 5GB to 20GB of space if you're a heavy texter. Also, inside the iPhone Storage menu, you can actually tap on "Messages" and see a list of "Large Attachments." It ranks them by size. You'll probably find a 200MB video of a random birthday party from 2019 that you definitely don't need to carry around anymore.
Photos: Stop hoarding duplicates and "bursts"
Apple’s "Duplicates" folder in the Photos app (introduced in iOS 16) is a godsend. Scroll down to "Utilities" in your Albums tab. Tap Duplicates. Merge them. It keeps the highest quality version and tosses the rest. It’s satisfying.
But let’s talk about the "Optimise iPhone Storage" setting. This is the single most important toggle for anyone struggling with space. If you have iCloud Photos turned on, go to Settings > Photos and make sure "Optimise iPhone Storage" is checked instead of "Download and Keep Originals."
What this does is clever: it keeps tiny, low-resolution thumbnails on your phone so you can still scroll through your life, but the massive, multi-megabyte original files stay in the cloud. When you tap a photo to look at it, it downloads instantly. You just saved 80% of your photo storage space. It’s basically magic, though it does mean you need a bit of data or Wi-Fi to see your old photos in full crispness.
The Safari "Rabbit Hole"
Safari is a silent hoarder. Every website you visit stores "cookies" and "cache" data so it loads faster next time. Over months, this adds up. Go to Settings > Safari > Clear History and Website Data.
Wait.
Before you nuked everything, did you know you can just delete the data for specific sites? Go to Safari > Advanced > Website Data. You might find that a random news site you visited once is holding onto 500MB of data for no reason. Swipe left to kill the heavy hitters individually.
Music and Podcasts: The accidental bloat
Streaming is great until you realize you’ve "downloaded" three seasons of a true-crime podcast you already finished. Podcasts are notorious for this. They download in the background, you listen, and they just sit there.
Check your TV app, too. Downloaded movies in 4K are massive—around 4GB to 6GB per film. If you downloaded Dune to watch on a train last month, it’s still there, eating a massive hole in your storage. Delete it. You can always download it again later since you own the license.
ProRAW and 4K60: The luxury tax
If you have a Pro model iPhone, you might be shooting in ProRAW or ProRes. These formats are for professional editors. A single ProRAW photo can be 75MB. A normal photo is 2MB. If you aren't planning on color-grading your photos in Lightroom, turn off ProRAW in your camera settings.

The same goes for video. 4K at 60 frames per second looks amazing, but it's a storage nightmare. For most people, 1080p at 60fps or 4K at 30fps is more than enough for Instagram or family memories. You can change this in Settings > Camera > Record Video.
Actionable Steps to Reclaim Your Phone
Don't try to do everything at once. Start with the "big wins" and work your way down.
- The 30-Second Fix: Go to Settings > General > iPhone Storage. Look at the "Recommendations" section. Apple usually suggests "Review Large Attachments" or "Empty Recently Deleted Album." Do what it says.
- The Cloud Shift: Ensure "Optimise iPhone Storage" is on in your Photo settings. This is usually the "silver bullet" for 90% of users.
- The App Purge: Look at the list of apps in that same Storage menu. If you see an app taking up 1GB that you haven't opened in 12 weeks, offload it.
- The Message Cleanse: Set your message history to delete after one year. It feels scary, but honestly, if you haven't looked at a text from 14 months ago, you probably never will.
- The Ghost Cache: If your "System Data" is still huge, back up your phone to iCloud, do a "Erase All Content and Settings," and then restore from that backup. It sounds extreme, but it's the only way to truly "deep clean" the iOS file system and get rid of stubborn cache files that won't leave.
Making space isn't a one-time chore; it's more like keeping a kitchen clean. You don't have to be a minimalist, but occasionally clearing out the digital "junk drawer" makes the whole experience of using an iPhone feel faster and less stressful. Start with the Duplicates folder in Photos—it’s the easiest win you’ll get today.
