The OnePlus 15’s official global specifications list 256GB and 512GB UFS 4.1 storage. Choose based on how much you keep on the phone—not just the starting price—and check which configuration is actually sold in your country. For accessories, an exact-model case is optional; a faster charger is worth considering only after checking what comes with your regional version.
Which OnePlus 15 storage variant should you buy?
OnePlus lists two capacities globally: 256GB and 512GB, both using UFS 4.1 storage. The listing does not establish that both are available in every market, so confirm the local SKU and price before deciding. OnePlus global specifications

Choose 256GB if you keep a moderate amount of content locally
The 256GB version is the lower-capacity choice. It may suit you if you regularly stream media, remove downloads you have finished with, and move photos or videos elsewhere rather than keeping a large archive on your phone.
Do these 3 things before closing this tab:
1Clear out junk files and repair common Windows errors2Scan for outdated or missing drivers - takes under a minute3Repair Windows errors before they cause bigger problemsConsider 512GB if you keep more on the phone
The larger option may be a better fit if you store substantial video and photo libraries, download lots of media for offline use, or install several large games. That is a practical inference from the listed capacities, not a measured estimate of typical OnePlus 15 storage use. Compare the local price difference with the value you place on keeping those files available without offloading them.

Check the actual local configuration and price
The global specification page does not confirm local pricing or availability. Before ordering, check the OnePlus page or authorized retailer for your country, and verify both the capacity and the exact model in the listing. The inspected official pages do not establish whether storage is expandable, so do not assume a memory-card slot is available—or absent—without checking the local specifications or manual.
What accessories do you need?
For most buyers, the first decision is whether to protect the phone with a case. OnePlus’s US product page names three OnePlus 15 magnetic cases: Sandstone, Hole-Pattern, and Aramid Fiber. Treat them as official examples, not proof that each style is sold in every country. Check the product listing for local availability, exact model fit, price, and any confirmed details about feel or weight. OnePlus US product page

Charger: check the box before buying one
OnePlus says the phone supports up to 80W SUPERVOOC wired charging and 50W AIRVOOC wireless charging. Its US product page also mentions up to 100W with the OnePlus SUPERVOOC 100W Dual Ports GaN Power Adapter Lite. These are manufacturer specifications, not independent comparative test results.
