The average smartphone shipped in 2025 carries 194 gigabytes of storage. That’s nearly double the figure from just five years ago. And most of it sits empty.
This is the quiet absurdity of the modern mobile device market: manufacturers are locked in a storage arms race that most consumers never asked for, don’t fully understand, and increasingly don’t need — at least not in the way they once did. Cloud services have changed the calculus. Streaming has changed it further. Yet every product cycle, the baseline storage tier creeps upward, and the premium tier pushes into territory once reserved for laptop hard drives.
According to detailed data compiled by Android Authority, average smartphone storage capacity has climbed steadily and dramatically since the dawn of the iPhone era. In 2007, the first iPhone shipped with either 4 or 8 GB. By 2012, the average had reached about 24 GB. By 2020, it hit roughly 110 GB. Now, in 2025, the industry average sits at 194 GB — with flagship devices routinely offering 256 GB as a starting point and 1 TB as a top-end option.
The trajectory is unmistakable. But the question the numbers raise is more interesting than the numbers themselves: Why does the storage ceiling keep rising when actual usage patterns suggest diminishing returns?
The Supply-Side Logic Behind Ever-Expanding Gigabytes
To understand the relentless upward march, you have to understand NAND flash memory economics. The cost per gigabyte of NAND flash has plummeted over the past two decades. In the mid-2000s, a gigabyte of flash storage cost roughly $8 to $10. Today that figure is closer to $0.05 to $0.08, depending on the type and volume. For phone makers, adding more storage costs almost nothing at the margin — but it gives marketing teams a bigger number to print on the spec sheet.
This isn’t cynical. It’s rational. Consumers comparison-shop on specs, and storage is one of the easiest numbers to compare. When Samsung offers 256 GB as its base Galaxy S25 configuration, Apple can’t afford to look stingy at 128 GB. So Apple moved its iPhone 16 Pro lineup to 256 GB minimum. And so the ratchet turns.
The Android Authority analysis shows that Apple’s average storage per device has grown from about 15 GB in 2010 to approximately 200 GB today. Samsung’s trajectory is similar. Chinese manufacturers like Xiaomi and OnePlus have been even more aggressive, frequently offering 256 GB and 512 GB options in mid-range devices where Western brands might still default to 128 GB.
There’s also a structural incentive at play. Higher storage tiers carry disproportionately high margins. The cost difference between a 256 GB and 512 GB NAND chip might be $8 to $15 for the manufacturer. The retail price difference? Often $100 or more. This is one of the most profitable upsells in consumer electronics — a tradition Apple essentially perfected with the iPod and has carried forward ever since.
So manufacturers want you to buy more storage. They want you to believe you need it. And to some degree, they’re creating the conditions that make it feel necessary.
App sizes have ballooned. The average top-100 iOS app now exceeds 200 MB, according to data tracked by app analytics firms. Games routinely consume 2 to 5 GB. Genshin Impact, one of the most popular mobile games globally, requires over 20 GB. Operating systems themselves have grown: a fresh iOS 18 installation consumes roughly 12 to 15 GB, and Android 15 is comparable. System partitions, cached data, pre-installed apps — all of it eats into the advertised number before a user even opens the box.
Photos and video remain the biggest consumer of storage for most users. A single 4K video clip shot at 60 frames per second on an iPhone 16 Pro Max burns through roughly 400 MB per minute. ProRes video — a feature Apple prominently advertises — devours approximately 6 GB per minute. Shoot a child’s soccer game in ProRes and you’ve consumed more storage than an entire early iPhone had to offer.
But here’s the twist. Most people don’t shoot ProRes. Most people don’t play Genshin Impact. Most people, according to multiple surveys over the years, use a fraction of their available storage.
A 2023 analysis by Counterpoint Research found that the median smartphone user consumed between 64 and 80 GB of their device’s storage. Power users — the kind who keep large local music libraries, shoot extensive video, or maintain hefty game collections — might push past 200 GB. But they represent a minority. The median user, the one who takes photos, runs social media apps, stores some downloaded Spotify playlists, and maybe keeps a few seasons of a Netflix show cached for a flight — that person doesn’t need 256 GB. They probably don’t even need 128 GB.
And cloud services keep compressing the need further. Google Photos offers 15 GB free and automatically backs up images. Apple’s iCloud provides tight integration that offloads older photos from device storage. Spotify and Apple Music have made large local music libraries obsolete for most listeners. Even offline viewing on Netflix and YouTube compresses content aggressively enough that a few hours of downloaded video might only consume 3 to 5 GB.
The On-Device AI Argument — and Its Limits
The newest justification for ever-larger storage comes from artificial intelligence. Apple, Google, and Samsung have all begun running AI models locally on their devices. Apple Intelligence, announced in 2024 and expanded through 2025, keeps certain language and image models on-device for privacy and speed. Google’s Gemini Nano runs directly on Pixel hardware. Samsung’s Galaxy AI suite processes some tasks locally.
These models do consume storage. Apple Intelligence requires roughly 4 to 7 GB of on-device model data, depending on which features are active. Google’s implementation is similar. And as these models grow more capable, their storage footprint will increase.
But even aggressive projections don’t justify the leap from 256 GB to 1 TB for the average user. On-device AI models in their current form add single-digit gigabytes of overhead. Even if that triples or quadruples over the next few product cycles, we’re talking about 20 to 30 GB — significant, but not transformative relative to total available storage.
The more honest explanation is simpler. Storage is cheap. Consumers like big numbers. And nobody ever got criticized for offering too much.
There is, however, a less discussed consequence of this dynamic. As base storage tiers climb, the entry price of flagship phones climbs with them — or at least resists downward pressure. When Apple moved the iPhone 15 Pro from a 128 GB base to 256 GB, the starting price held at $999. The consumer got more storage. Apple protected its margin. Both sides could claim a win. But the consumer who would have been perfectly happy with 128 GB at $899 didn’t get that option.
This is particularly visible in developing markets, where storage costs still represent a meaningful portion of a device’s bill of materials. Android Authority’s data shows that budget Android phones — devices in the $100 to $200 range — have also seen storage increases, moving from 16 or 32 GB a few years ago to 64 or 128 GB today. For these consumers, the upgrade is more meaningful. A phone with 32 GB of usable storage after accounting for the OS genuinely runs out of space. A phone with 128 GB rarely does.
The mid-range sweet spot, for most global consumers, appears to be 128 GB. It’s enough for a generous photo library, a dozen apps, some cached media, and room to breathe. But the industry has little incentive to tell people that 128 GB is plenty. The incentive runs in exactly the opposite direction.
Samsung’s latest Galaxy S25 Ultra ships with 256 GB, 512 GB, and 1 TB options. The 1 TB model costs $1,419. That’s a lot of money for storage most buyers won’t fill. But Samsung knows that a certain type of buyer — the spec-maximizer, the future-proofer, the person who simply wants the best — will pay it. And the margin on that NAND upgrade is extraordinary.
Apple plays the same game with the iPhone 16 Pro Max. The jump from 256 GB to 1 TB adds $400 to the price. The actual hardware cost difference? Industry analysts estimate it’s somewhere between $30 and $50.
Not a bad business.
Where This Goes Next
The storage escalation shows no signs of slowing. Industry roadmaps from NAND manufacturers like Samsung Semiconductor, SK Hynix, and Kioxia point toward continued cost reductions as layer counts in 3D NAND increase. Samsung has already demonstrated 300-plus layer NAND, and the industry is pushing toward 400 and beyond. Each generation brings lower cost per bit.
That means 512 GB will likely become the new flagship default within two to three years. And 2 TB phones — which would have sounded absurd five years ago — are technically feasible today and will become commercially viable soon. Whether anyone needs 2 TB in their pocket is another matter entirely.
The counterargument from manufacturers is that storage needs always grow to fill available capacity. They said 16 GB was enough once. Then 32 GB. Then 64 GB. Each time, usage expanded. Apps got bigger. Cameras got better. Media got richer. The assumption is that this pattern will continue indefinitely — that 8K video, ever-larger AI models, augmented reality content, and applications we haven’t imagined yet will eventually make 1 TB feel tight.
Maybe. But the rate of consumption growth has slowed even as the rate of capacity growth has accelerated. The gap between what phones offer and what people use is widening, not narrowing. Cloud infrastructure continues to improve. 5G networks make streaming and cloud access faster and more reliable, reducing the need to store content locally.
And there’s an environmental angle that rarely enters the marketing conversation. More NAND per phone means more silicon, more energy in fabrication, and more material that eventually enters the waste stream. When a significant portion of that silicon goes unused for the life of the device, the inefficiency is real — even if it’s small per unit.
None of this will change the industry’s direction. The economics are too favorable, the marketing too compelling, the competitive dynamics too entrenched. Storage numbers will keep climbing. Consumers will keep buying. And most of those gigabytes will sit quietly in the dark, waiting for data that never arrives.
The smartphone storage race isn’t about what users need. It never was. It’s about what manufacturers can profitably offer, what competitors force each other to match, and what consumers can be persuaded to want. By those measures, the race is working exactly as designed.
