A GUIDE TO DECIDING
The right iPhone capacity depends on what you keep and how you manage it. Before choosing 128 GB or 256 GB, inspect the space used on your current phone. Separate content you need available at all times from files you can download or keep elsewhere.
Start with your current usage and allow room for growth. More storage may be useful, but it does not replace checking the condition of the actual used phone.

Check iPhone storage in Settings and identify the contribution of photos and video, applications, downloads and other data. If you are near the limit, decide what you would retain and what you could manage differently before comparing listings.
Usable space is lower than nominal capacity because the system and other data also take up room. Avoid assuming that your storage use will remain unchanged for the entire time you own the next phone.
128 GB may be worth evaluating if your existing usage is modest and you manage downloads. Compare 256 GB if you record video, use large applications or need content offline. Frequent access to a computer can change your approach compared with keeping everything on the phone.
A cloud service may be part of your file organisation, but it does not physically turn a 128 GB iPhone into a 256 GB device. Consider connectivity, settings and any service cost if your plan relies on accessing content remotely.
Filter the used iPhone catalogue by capacity, then compare model, battery and condition. A better-kept 128 GB phone and a faulty 256 GB phone are different purchases; ask for the complete details before deciding.
It provides more storage headroom, but value depends on your usage and the individual phone. Compare battery, condition, model and total price too.
No. Device and cloud storage are different. Consider how you would use each and what you need available without an internet connection.
Review current usage, the files you want to retain and likely growth. The number of installed applications alone is not a useful capacity estimate.
Listings describe individual devices. Price, condition and availability can change.
Stock changes; if the configuration you want is missing, ask about alternatives.
