If you've owned your iPhone for a long time, you know the f when you're about to snap a photo, download an app or update your phone, when suddenly a notification pops up warning you that your iPhone storage is almost full. Maybe you've frantically tried to figure out how to free up as much space as possible without just nuking everything. 

But don't panic. There are several ways to regain storage space from your iPhone that don't involve starting from scratch. From offloading apps to using the cloud, we've compiled a helpful list of ways to help you make more room on your iPhone and manage your storage in a smarter, more efficient way. 

How to check what's taking up the most storage

Before you do any serious iPhone excavation, it's best to find out just what is taking up so much space in it. To do so, go to Settings, then General and then select iPhone Storage. You'll then see a colored bar chart breaking down the types of files and media that are on your phone. This is a great starting point because it'll tell you which type of storage is taking up the most space and you can choose to tackle that first. 

Additionally, Apple also makes recommendations in this section to help you free up more space, such as reviewing downloaded media or removing automatic downloads in podcast apps. 

Deleting or offloading apps you don't use much

The aforementioned iPhone Storage page will also list apps according to how much space they take up in your phone. It'll also tell you the last time you used it. You can scroll through this list to see if you should be deleting any of the apps that you haven't used in a while. You can delete them manually and redownload them later if you change your mind. 

An easier way to handle this, however, is to have your iPhone automatically remove unused apps. On that iPhone Storage page, you can tap Enable next to Offload Unused Apps. Those unused apps will live on iCloud Drive (you can find them in the Files app). If you want to use them again, simply tap them (they'll be marked with a cloud symbol) and they'll be redownloaded. 

Optimize photo storage by using the cloud

If the bulk of your storage issues lies in your photo library, you're certainly not alone. Fortunately, you can mitigate this by using iCloud to automatically upload and store your photos and videos. You can then choose to store the original, full-resolution version of them in iCloud while keeping just smaller versions of them locally. To enable this, go to Settings, then scroll down and tap Apps, then scroll down and select Photos. Be sure that iCloud Photos is enabled and then select Optimize iPhone Storage. You are always free to download the full-resolution versions of your files at any time. 

You could also consider using a third-party cloud storage service like Google Photos as a backup solution. Since deleting photos from your iPhone also removes them from iCloud, this is a smart idea if you plan on deleting some photos from your device but still want them in storage. 

Transfer files off your phone and onto an external drive

Another way to free up space on your phone is to transfer files to an external storage solution like a USB drive or SD card. Simply connect the external storage to your iPhone via a cable and you can use a supported app like Files or Pages to copy files directly to the storage device. You may then transfer the files from your external drive to anywhere you like, such as your laptop or computer. If those files are important to you, it's a good idea to back them up on cloud services like Box or Dropbox as well. 

Clear out data from within apps

Sometimes the biggest data hog lies within other apps. If you've downloaded videos and music to consume offline for example, they might still be taking up valuable space in your phone. One easy way to go through these is to go to that iPhone Storage page mentioned earlier (you get there by launching Settings, then tapping General and then selecting iPhone Storage). 

From there, you can scroll through the list of apps to find one that you've downloaded content from, like Netflix. Tap on that app's name and at the bottom of the page (below the Delete App link) you will see a list of downloaded content, which you may then swipe to delete. Alternatively, sometimes you might get a "Review Downloaded Media" recommendation on the iPhone Storage page. If you select that, you'll see downloaded media from across several apps so you can delete them with ease. 

It's important to note, however, that this method doesn't work with all media apps. YouTube, for example, doesn't display downloaded media in the iPhone Storage page, and neither does Apple's Podcasts app. However, you'll still know if those apps hold a lot of data if they rank high on the list of the amount of space the app takes up. On my phone, for example, YouTube stores a whopping 33.82GB worth of Documents & Data and is therefore the biggest data hog on my phone. If you know which app has a lot of data stored in it, you can go to that app directly to delete any unnecessary media. 

If you like downloading maps to your phone for offline viewing, that could be another reason your phone storage is full. In order to remove them, go to Maps on your iPhone, select your profile photo, and then select Offline Maps. You can either then manually remove a map by swiping and deleting, or simply select Optimize Storage to automatically delete unused maps. 

Steps You Can Take Right Now to Avoid an Overheated Phone

We're barely into summer and already the US has seen a devastating heat dome pushing temperatures to uncomfortable heights. And if you're hot, know that your phone is even hotter, which can make it turn off abruptly or potentially damage the battery.But there's no need to get hot and bothered, especially when you know these easy ways to keep your iPhone or Android phone from overheating.See also: What else can you do to keep cool? Here are more practical tips for your phone, plus ways to stay cool indoors.

Manufacturers like to boast about how bright their phone screens can get, allowing you to see your display clearly even in direct sunlight. Pushing the intensity of those pixels to 1,000 or 2,000 nits of peak brightness is great for reading what's on the screen, but sustaining that level uses more power and generates more heat than when you're inside or in the shade.Plus, direct sunlight delivers radiant heat to items like metal and glass, increasing the temperature of your device. If you need to use your phone for an extended period of time during sunny, hot days, find some shade to protect both it and you.

If you don't want to expose the phone to the sun, what about keeping it in a car while you're frolicking on the beach? Setting aside the risk of having it nabbed in a break-in, cars turn into hotboxes on sunny days, which can easily push past the recommended operating temperatures. It's better to take the phone with you.Which reminds me: I know you'd never leave a pet in a hot car, but they can get overheated elsewhere. Here's how to take care of your vulnerable furry friends.

It's normal for a phone to heat up while it's charging -- the phone's surface dissipates that heat away from the inside by design. But if you're using a bulky case, the heat could get trapped. If the phone seems to be heating up too much when plugged in, remove the case before charging.

Heat doesn't just come from the outside environment.Your phone's processor has to work a lot harder when you do something like play graphics-intensive games, which can generate more heat than usual from within your device.And playing these games can also drain your battery quickly, so it's natural to want to plug into power.However, this combination of high processing and charging increases the heat generation even more, leading to overheating.

Video recording is resource-intensive, capturing and storing multiple megabytes of data per second and usually processing that footage at the same time. Even expensive mirrorless cameras capable of shooting high-quality video hit thermal ceilings (or have add-on fans to dissipate the heat). If you're recording lengthy clips, you may need to pause for a few minutes between them to allow the phone to cool down.

It's just a power charger, so why not get the cheapest one? Be wary of amazingly low prices, because they're often attached to knock-off products that don't include safety electronics for regulating power throughput and preventing overheating. It's better to pay slightly more and get a recommended USB-C charger or power bank that you know you can trust.

It sounds like the worst sort of overly general advice: Make sure your device's software is up to date. And yet it's usually good advice, especially in this case. For example, a bug in iOS 17, plus a problem with some apps, including Instagram and Uber, caused many iPhone 15 Pro phones to overheating. Apple soon released an update to fix the problem.Note that it's normal for a phone to warm up during and after a system update as the software optimizes data in the background. However, this is a temporary temperature elevation.Also, if you're running prerelease software such as the iOS 26 beta or the latest Android 16 beta, it's not uncommon for phones to run a little hot because the software usually doesn't get optimized for battery life until just before launch.

If you can't avoid the heat and often find yourself waiting for the phone to cool, consider buying an inexpensive thermal phone pouch to store it in. Using materials designed to protect astronauts from temperature extremes, a pouch will reflect direct sunlight and heat away from the phone. Thermal pouches also work at the other end of the spectrum, protecting your phone from cold weather, such as when you're skiing.

If overheating becomes a frequent problem -- and the phone isn't exposed to the other situations mentioned in this gallery -- a faulty or failing battery might be the cause.First, see what the phone is telling you: on the iPhone, go to Settings > Battery and check Battery Health. On Android, go to Settings > Battery > Battery Diagnostics (Pixel) or Settings > Battery information (Samsung). If the functionality is degraded, it might be time to schedule a battery replacement.And if the phone is bulging, cracked or shows other signs of a swollen battery, turn it off and contact the company's support programs immediately. That's a less likely circumstance, but with lithium-ion batteries, you don't want to mess around with safety.
