How much phone storage do I actually need?
Work it out from what you currently use rather than guessing — and why underspending here is the expensive mistake.

Short answer
Look at what you are using now and roughly double it for a phone you will keep three or four years. Storage cannot be upgraded later, so underspending is the one specification mistake you cannot correct.
Storage is the specification most likely to be regretted, because it is the one that cannot be changed afterwards. The good news is that your current phone tells you exactly what you need.
Step by step
- Check what you are actually using now.Settings, storage. It breaks down by category. This number, not a guess, is the basis for the decision.
- Look at what is using it.Photos and video are usually the majority. If you take a lot of video, storage requirements rise sharply — video is many times larger than photographs.
- Double your current usage as a rule of thumb.For a phone kept three or four years. Usage grows: apps get bigger, cameras record at higher resolution, and photo libraries only ever increase.
- Remember the system takes a share.A phone advertised as 128GB has noticeably less available. Do not plan to the advertised figure.
- Decide honestly about cloud storage.It genuinely reduces the need if you use it properly and pay for enough of it. But it needs a connection, and "optimise storage" settings still keep recent files locally.
- Check whether the phone takes a memory card.Many no longer do. Where it is available it is a cheap way to extend media storage, though apps usually still need internal space.
- Weigh the upgrade cost against the alternative.The jump to more storage is often less than a few years of cloud subscription. Compare the two properly rather than assuming the cheaper phone is cheaper.
- Err upward.Storage is the one thing you cannot add later. Running out means deleting things you wanted or replacing the phone early.
Tips
- If you take a lot of video, jump a tier. A few minutes of high-resolution video is larger than hundreds of photographs.
- The base storage tier is frequently too small for a phone kept several years. The middle tier is the sensible default for most people.
- Before buying more storage, check how much of your current usage is cached data and unused apps. It is sometimes a third.
Questions people ask
How much storage do I need on a phone?
Roughly double what you use now, for a phone you will keep three or four years. Check the actual figure in settings rather than guessing.
Can I add storage later?
Almost never on a modern phone. A memory card slot is rare now, and internal storage cannot be upgraded — which is why erring upward matters.
