You know that feeling. You're trying to capture a perfect, candid moment—maybe your kid’s first steps or a sunset that actually looks good on camera—and that dreaded "Storage Almost Full" notification pops up. It’s infuriating. Honestly, it feels like a personal betrayal by a device you paid a thousand dollars for. Most people think their only options are to pay Apple $9.99 a month forever or start a digital massacre of their favorite memories.
They're wrong.
Getting more space isn't just about deleting apps. It's about understanding the weird, bloated way iOS handles data. Your iPhone is a packrat. It keeps things you didn't even know existed, from "System Data" ghosts to redundant photo copies. If you've been wondering how to get more storage on iPhone, you need a strategy that targets the invisible weight, not just your camera roll.
The Invisible Culprit: Why Your iPhone Thinks It's Full
Before you start trashing apps, look at the "Other" or "System Data" bar in your storage settings. You'll find this by heading to Settings > General > iPhone Storage. Sometimes that grey bar takes up 20GB or more. It’s infuriating because Apple doesn't give you a "Delete" button for it.
This category is basically a graveyard of caches. It's Netflix movies you "deleted" but the phone is still holding onto the temporary files. It's Safari history from three years ago. It's the Siri voices you downloaded and forgot about. To clear this, you often have to trick the phone. One weirdly effective method is simply syncing your phone to a computer (Mac or PC). It sounds archaic, but the handshake between the iPhone and a computer often triggers a cleanup of these log files.
Photos are Usually the Real Problem
Let's talk about the elephant in the room. Photos. Specifically, the fact that you probably have 400 photos of your cat that all look identical. But wait. Before you go on a deleting spree, check your High Efficiency settings. If you go to Settings > Camera > Formats, make sure "High Efficiency" is checked. This uses the HEIF/HEVC format. It literally cuts file sizes in half without losing quality. If you’ve been shooting in "Most Compatible," you’ve been wasting 50% of your storage for years.
Then there’s the "Optimize iPhone Storage" trick. This is the single most important setting for anyone struggling with space.
- Go to Settings.
- Tap your name.
- Hit iCloud > Photos.
- Ensure Optimize iPhone Storage is toggled on.
What this does is clever: it keeps the full-resolution versions in the cloud and leaves a tiny, low-res thumbnail on your phone. When you click the photo, it downloads the high-res version instantly. It’s seamless. You can keep 50,000 photos on a 64GB phone this way. Seriously.
The "Offload" Secret vs. Deleting
Most people just delete apps. That's a mistake. When you delete an app, you lose your data, your logins, and your progress. Instead, use Offload Unused Apps. This is tucked away in the App Store settings or the Storage menu.
Offloading removes the app itself (the "code") but keeps your "Documents & Data." The icon stays on your home screen with a little cloud symbol. When you need it, you tap it, it redownloads in seconds, and you’re right back where you left off. It’s perfect for that airline app you only use twice a year or that game you’re currently bored with but don't want to lose your level 100 save file on.
Messages: The Silent Storage Killer
We don't think about texts as taking up space. But if you've been texting for five years and sending videos, memes, and GIFs, your Messages app is likely a multi-gigabyte monster.
Go to Settings > Messages > Keep Messages. Is it set to "Forever"? Change it. Set it to 1 year or 30 days. Your phone will automatically prune the ancient stuff. If you can't bear to lose the texts, at least go to the iPhone Storage menu, tap "Messages," and look at "Top Conversations." You'll likely see a few group chats where people have been sending 100MB video clips of their dogs. Delete those specific videos within the storage menu, and you'll claw back gigabytes in seconds.
The Safari Cache Cleanout
Safari is a hog. Every website you visit stores a little bit of data to "load faster" next time. Over months, this adds up. Go to Settings > Safari > Clear History and Website Data.
Warning: This will log you out of most websites. It's a minor pain, but it's a quick way to find an extra 500MB to 1GB of space when you’re in a pinch. Also, check your "Reading List." If you’ve been saving articles for offline reading, they’re sitting on your hard drive. Swipe left on them in Safari to get rid of the offline versions.
Stop Downloading Music and Podcasts Automatically
Streaming is your friend when you're low on space. Apple Music and Spotify have settings that "Optimise Storage." In Settings > Music, you can set a limit (like 4GB). Once you hit that limit, the phone will automatically delete the songs you haven't listened to in a while to make room for new stuff.
Podcasts are even worse. If you subscribe to five shows that post daily, you could be downloading 500MB of audio every single day. Go into your Podcast app settings and turn off "Enable Downloads." Just stream them. We have 5G now; you don't need to carry the files around like it's 2005.
Reinstalling Social Media Apps
This is a pro tip. Apps like Instagram, Facebook, and TikTok are notorious for "cache bloating." They don't have a "Clear Cache" button in the settings. The only way to fix it is to delete the app entirely and reinstall it.
Try it. Check how much space TikTok is taking up right now. It might be 2GB. Delete it. Reinstall it. Suddenly, it’s only 300MB. Do this once every few months for your most-used social apps to keep the bloat under control.
Dealing with "System Data" once and for all
If you’ve tried everything and that "System Data" bar is still huge, there is one "nuclear" option that actually works. It's the Backup and Restore.
Basically, you back up your phone to iCloud or a computer, then go to Settings > General > Transfer or Reset iPhone > Erase All Content and Settings. Once the phone is blank, you restore it from your backup. This forced "re-indexing" clears out the junk files that the OS refuses to delete on its own. It's a hassle. It takes an hour. But it’s the only way to truly "reset" your storage health.
Actionable Steps to Take Right Now
Stop reading and do these three things immediately. They take less than two minutes and will likely give you at least 2GB back.

- Check for "Large Attachments" in Messages: Go to Settings > General > iPhone Storage > Messages > Review Large Attachments. Delete the videos you've already seen.
- Offload your "Zombie" Apps: Scroll down that same Storage list. See an app you haven't opened since 2023? Tap it and hit "Offload App."
- Empty the "Recently Deleted" Album: Photos you delete stay on your phone for 30 days. They still take up space! Go to your Photos app, scroll to the bottom, tap "Recently Deleted," and nuked them all.
Following these steps ensures you don't have to keep playing the "delete one photo to take one photo" game. Your iPhone should work for you, not the other way around. Keep your storage lean, and you'll notice the whole phone actually runs faster too.
