iPhone Storage Guide: How Much Space Do You Actually Need?
Of all the specs on a phone listing, storage is the one that actually matters most day to day — and it's the one you can never add more of later. There's no SD card slot on an iPhone, no upgrading it in six months when things get tight. So it's worth thirty seconds of actual thought before you buy, rather than just picking whatever's cheapest.
What actually eats your storage
Apps themselves are usually small. What fills a phone up is photos and video — especially 4K video, which chews through gigabytes fast — plus the apps that cache huge amounts of data over time (think Instagram, TikTok, Spotify downloads, WhatsApp media). iOS itself also quietly takes up several gigabytes, so the number on the box is never quite the number you get to use.
64GB – fine for light, deliberate use
If you mostly use your phone for calls, messaging, maps and browsing, don't shoot much video, and you're disciplined about deleting old photos or backing them up elsewhere, 64GB is genuinely enough. It's also the cheapest way in — our $239.00 iPhone SE 64GB is a good example of what that tier looks like in practice. Where it goes wrong: if you're the type to take fifty photos of the same sunset and never clean out your camera roll, 64GB will feel small within a year.
128GB – the sensible default for most people
This is where most buyers land, and for good reason. It comfortably holds a few years of normal photo and video use, a full set of apps and games, and offline music or podcasts, without you having to think about it much. An iPhone 13 128GB, for example, sits around $539.00 in excellent condition — a small step up from 64GB for a meaningfully bigger buffer.
256GB – for heavier photo/video users
If you shoot a lot of video, use your phone as your main camera for a hobby or small business, download a lot of offline content (Netflix, Spotify, podcasts for flights), or just never delete anything, 256GB is worth the jump. An iPhone 12 Pro Max 256GB currently runs around $639.00.
512GB and 1TB – a smaller, specific audience
Realistically this tier is for people shooting a lot of 4K/ProRes video, running large offline music or film libraries, or who simply never want to think about storage again. We occasionally get 1TB models in, like an iPhone 13 Pro Max 1TB around $899.00 — worth it if you know you need it, overkill if you don't.
The cloud doesn't fully solve this
iCloud or Google Photos can offload your library and free up space, but you're then paying a monthly subscription indefinitely, and you still need local space for the apps and files you use daily — it delays the problem rather than removing it. Buying slightly more storage upfront is usually cheaper over two or three years than paying for cloud storage the whole time.
The simple rule
If you're unsure, buy one tier above what feels obviously enough — 64GB users are happier at 128GB, and 128GB users who do a lot of photo or video are happier at 256GB. Going bigger costs relatively little extra at the refurbished price point; going back for more later isn't an option at all.
