Smartphones serve a wide variety of functions that improve your quality of life, but all of these functions need adequate phone storage, and every phone is different with how much space it gives.
Knowing how you use your phone and what you use it for the most helps you figure out how much phone storage you need, depending on what fits in your budget.
It will also be helpful to know what features on your phone are taking up space and how much space they need. Photos, videos, apps, messages, and other pieces of data take up your phone’s storage capacity faster. For example, a single quality photo can take up 3-8MB. But 4K video footage can take as much as 400MB per minute. The average smartphone user accumulates roughly 2-5GB of storage each month through photos, app updates, and cached data alone.
It’s also worth mentioning that phones usually need 10-15% of total storage to remain free just to work properly, which further limits the usable space you actually have. And while the average smartphone user has around 80 apps installed, research from YourNavi suggests that users actively use only about 9 of them on a regular basis – meaning a portion of storage is usually tied up in apps that don’t get opened.
Fortunately, there are ways to manage this. Cloud storage plans usually cost just $1-$3 per month for 100-200GB of space, which makes them an affordable option for offloading photos and files. If you’d like a physical upgrade, expanding your storage tier at the time of purchase usually runs $50-$200 more depending on the device. According to Ofcom’s Communications Market Report 2025, the average person used 10.6GB of mobile data per month in 2024, which is a helpful benchmark when looking at how much local storage you actually need versus what you can use the cloud to manage.
What Is Internal Phone Storage?
Modern smartphones have internal storage installed by the manufacturer, which holds the operating system, pre-installed apps, and other system software. It’s also where your downloaded data lives, like apps, messages, photos, music, and more. As of 2026, most new smartphones ship with a baseline of 128GB of internal storage, with higher-end models giving 256GB, 512GB, or 1TB. The days of 16GB or 32GB as standard are largely behind us, though older or budget devices may still carry those limitations.
The storage capacity advertised on a phone is never fully available to you. The operating system and pre-installed apps take up a portion right out of the box, and phones usually need 10-15% of total storage to remain free just to work. So a “128GB phone” may only give you around 100-110GB of usable space in practice.
Some Android phones still support a microSD card slot, which lets users expand their storage externally. However, this feature has become increasingly rare, as manufacturers – like most flagship Android brands and Apple across all iPhone models – have moved away from it in favor of cloud-based services and higher built-in storage tiers.
To put storage needs in perspective, a single quality photo takes roughly 3-8MB. But 4K video can take around 400MB per minute. The average smartphone user can add roughly 2-5GB of data per month through photos, app updates, and cached data alone. With the average person using 10.6GB of mobile data per month according to Ofcom’s Communications Market Report 2025, picking the right amount of internal storage from the start matters more than ever.
How Does Phone Storage Differ From Memory and Random Access Memory (RAM)?
RAM and phone memory are not interchangeable terms. That distinction matters. RAM (Random Access Memory) is short-term memory your phone uses to manage active tasks. But internal phone storage is where your photos, apps, videos, and files live permanently. When you open a web browser, your camera app, a ride-sharing app, or anything similar, your phone loads that data into RAM to process it faster. When your device restarts or powers off, everything in RAM clears out. Internal storage, on the other hand, retains your data indefinitely until you delete it.
RAM operates much faster than internal phone storage, which is why it exists – to speed up your system by taking care of quick, temporary bursts of data without burdening your long-term storage. However, your smartphone has less RAM than it does internal storage, and unlike external storage options, RAM can’t be expanded after purchase.
Internal phone storage is where the capacity decisions come into play. A single quality photo can take up 3-8MB. But 4K video can take around 400MB per minute. The average smartphone user goes through roughly 2-5GB of storage per month through photos, app updates, and cached data alone – it’s also worth keeping in mind that phones usually need 10-15% of total storage to remain free just to work, so your usable space is always a little less than the advertised number.
What Are My Phone Storage Options?
You have a few options concerning your phone’s storage capacity. With an intangible measurement like gigabytes, it can be hard to know how much storage to get for your phone. Here is an overview of what your options are and what you’ll get out of each one.
64GB
A 64GB phone sits at the lower end of what most modern smartphones give you in 2026. While it can work for light users, you’ll need to be strategic about what you store locally. Remember that phones usually need 10-15% of total storage to remain free just to work properly, which immediately eats into your usable space. Cloud storage services can help offset this – plans usually run just $1-$3 per month for 100-200GB – but you’ll need a reliable connection to make the most of them.
If you primarily stream music and video instead of downloading them and you don’t shoot photos or 4K video, 64GB may be manageable. However, most users will find themselves bumping up against this limit sooner than expected.
128-256GB
For the average smartphone user in 2026, 128GB is usually considered the sweet spot. The average person uses around 2-5GB of storage per month through photos, app updates, and cached data, which means 128GB gives most users a few years of comfortable breathing room. It also accommodates the reality that a single 4K video can take as much as 400MB per minute, and even a standard quality photo takes 3-8MB.
256GB is the best choice if you shoot video, travel frequently without reliable cloud access, or simply like not having to think about storage management.
512GB+
High-end flagship phones now give you 512GB and even 1TB of internal storage. These are a good choice for content creators, heavy mobile gamers, or anyone who records large volumes of 4K or high-resolution footage directly to their device. Stepping up to this tier usually costs an extra $50-$200 over the base storage model, so it’s worth assessing your habits before paying the premium.
That said, if you’ve ever deleted photos to free up space or felt nervous about a low-storage warning, upgrading to 512GB or more will probably be worth every penny for the security alone.
What Takes up My Phone Storage?
We know that apps, messages, photos, videos and other types of data take up space on a phone. There are also other things you should know about that you might not have thought about in the past.
Your screen resolution takes up space on your phone. If you’re looking to buy a phone with very high resolution, you might want to invest in more storage.
If you are into playing video games on your phone, that alone should cause you to invest in more storage. Remember that your game’s graphics quality can also be affected by the amount of storage available on your device.
Using your email on your phone can also need storage, and that’s also the case if emails you send and receive hold attachments.
It’s also worth mentioning that phones usually need 10-15% of total storage to remain free in order to work. So even if your phone isn’t full, you might start to see performance problems as you approach that threshold.
Here are breakdowns of how much storage tasks take up.
Photos
A single quality photo usually takes up anywhere from 3-8MB, depending on your camera settings and resolution. As a general rule of thumb, budgeting around 16GB for every 2,000-5,000 photos is a basic estimate depending on the quality you’re shooting in. Photos are one of the most common sources of storage problems. But learning about roughly how much space your photography habits need can save you a headache later.
On iPhones, you can turn on a setting called “Optimize iPhone Storage,” which will save your full-size media to iCloud and replace it on your device with smaller, optimized versions. Using this feature can cut back on how much internal storage your photo library occupies.
Videos
As phone cameras continue to improve, the storage demand for videos has grown substantially. An hour-long video recorded at 1080p will take up roughly 1.5GB. But the same length filmed at 4K can take far more – 4K footage can use as much as 400MB per minute, which means a single hour could occupy over 20GB. Video files are bigger than image files, so being mindful of how you record and at what resolution matters in how quickly your storage fills up.
Music
Music you stream on your phone doesn’t take up space past the app’s data and cache. Downloading music is where storage starts to disappear. On Spotify, premium users can choose the quality at which they download songs. A quality downloaded song can take up around 10MB. But a lower-quality version may only need around 3MB.
If you are never without Wi-Fi or a mobile data connection, there isn’t much reason to download music, as streaming it on demand is a helpful alternative that keeps your local storage free.
Apps
Apps can vary widely in how much storage they occupy, and their sizes grow over time as you use them and accumulate data. This is especially true of social media apps. The average smartphone user has around 80 apps installed but only actively uses about 9 of them on a daily basis. Periodically auditing and deleting apps you no longer use is one of the easiest ways to reclaim storage space.
Downloads
If you like having access to movies and shows without needing a connection, then you’ll need to set aside a significant chunk of storage for offline downloads. On Netflix, a one-hour episode at standard definition consumes around 280MB. But a high-definition episode is going to need approximately 440MB. These numbers stack on top of the space the app itself already takes up, so it adds up faster if you download content before traveling or commuting.
How Do I Choose Phone Storage?
Using the numbers above can be helpful if you know the types of data you normally store on your device. If you run out of storage on your latest phone, consider increasing the amount based on how much more data you would store if you were able to.
The best way to start picking the right phone storage is by looking at your mobile device habits. What are a few things that relate to your phone? Are you the photographer of your friend group, or do you love capturing videos of life’s moments? Are you a big-time gamer, a lover of movies, an avid traveler or all of the above?
To put storage consumption into perspective, a single quality photo takes up 3-8MB. But 4K video footage can take as much as 400MB per minute. The average smartphone user accumulates roughly 2-5GB of data per month through photos, app updates and cached data alone. According to Ofcom’s Communications Market Report 2025, the average person also used 10.6GB of mobile data per month in 2024, which gives you a strong baseline for estimating what works.
Traveling, in particular, is usually going to require you to use different apps — like navigation apps like Google Maps and Waze, alongside photo and video apps that can fill up storage faster during a trip.
Another factor to consider is whether you have another phone. If you use a work phone or some type of secondary device, your main phone will have more space, as you won’t have to use it for emails or other work responsibilities.
It’s also worth knowing that your phone usually needs 10-15% of its total storage to remain free just to work. So if you buy a 128GB phone, you realistically have closer to 108-115GB of usable space after accounting for the operating system. That is your performance buffer.
Research from YourNavi found that the average smartphone user has around 80 apps installed but only actively uses 9 of them. Auditing your apps and removing ones you don’t open is one of the simplest ways to keep storage under control.
A rule of thumb for the casual smartphone user is to choose a phone with at least 128GB of storage. With app sizes growing, cameras improving and 4K video becoming standard, 64GB is increasingly tight for everyday use.
If you are working with a small budget and can’t afford the amount of storage you need on your device, you can use some helpful tools and take steps when your phone runs out of storage.
Use a MicroSD Card
If your phone lets you, you can add a microSD card, which functions as external storage that doesn’t affect your phone’s internal storage. A microSD card lets you move data on the card to other devices. If you have an iPhone, this will sadly not be an option. But this option is available for Android phones. Physical storage upgrades usually cost $50-$200 per tier, so it’s worth comparing that cost against a cloud storage subscription depending on your preferences.
Take Advantage of Cloud Storage
Cloud storage is a great way to keep your data safely backed up even if you’re not out of storage. If you don’t have enough storage space, backing up your data on the cloud lets you delete that same information off your device. In turn, getting rid of some of this data will bring you closer to your base storage and free up your device for other things.
Apple devices connect to iCloud, though you could also use other cloud storage services like Google Drive. Since Apple devices don’t have a microSD card slot, a cloud solution is an especially helpful option. Cloud storage is also quite affordable, usually costing just $1-$3 per month for 100GB-200GB of space, which makes it an affordable alternative to buying a higher-storage device outright.
Android devices have options like Google Drive, Dropbox and OneDrive for cloud storage. Similar to iCloud, these services allow you to access your data from multiple devices without it taking up much internal storage on any of them.
Free up Space Manually
In your phone’s settings, you’ll see an overview of how much storage different types of data use. You can then go through your device and delete what you no longer need – this could be photos, videos, messages, apps or other types of data.
You can also free up space by deleting the cache data on apps and browsers. Keep in mind that deleting information in your cache will clear your internet files. But it might not make a big enough change in your storage capacity for you to notice. Deleting your cache data is usually as easy as clearing your internet history. Check the settings on the apps you use to see if they have an option to clear their data.
