OnePlus 15 (256GB): problems, parts and running costs

Checked: 2026-10-07

Summary

The OnePlus 15 (256GB) is a Snapdragon 8 Elite Gen 5 flagship with a 7,300mAh battery and 80W charging, sold in the US only in Infinite Black. The recurring complaints are cameras that trail the OnePlus 13, occasional heating under gaming or at 165Hz, and uncertainty after OnePlus left the US market in July 2026. It was strong value at its $899.99 launch price, but it is no longer sold through official US channels.

Common problems and fixes

Cameras trail the OnePlus 13 — the most common complaint: smaller sensors, no Hasselblad color science, and softer low-light or over-processed output. The telephoto does step up to 3.5x optical zoom. There is no fix beyond waiting for software updates; buyers who put cameras first should look at Google or Samsung instead. [8][9][5]
Heating under load — some owners report the phone heating after 10-15 minutes of heavy gaming, and one says enabling 165Hz made it heat up during normal use. Others praise the vapor chamber and report no overheating during emulation below 38°C, so results vary by unit and workload. [13][14][12]
No mmWave 5G — the phone does not support mmWave, which can limit 5G performance on some US carriers. [7]
Wireless charging is standard Qi only — there is no Qi2 magnetic support; OnePlus sells magnetic cases as an accessory, but the phone itself is not Qi2 Ready. [6]
Short software-support window — some owners call the 4-year update policy disappointing for hardware this capable. [11]
Uncertain long-term service after the US exit — OnePlus confirmed it is leaving the US and European markets on July 16, 2026 and promised continued support, with existing devices moving from OxygenOS to ColorOS via the Android 17 update; US stock sold out by early August 2026, so parts and service-center access are unclear. [3][4][10]
Green-line display faults — a GSMArena user opinion reports the green-line problem across multiple OnePlus devices in one family; prevalence on the OnePlus 15 specifically is not known. [15]
Slippery Sand Storm finish — WIRED describes the Sand Storm color as incredibly slippery, though the 256GB model is Infinite Black only. [6]

Parts and consumables

No replaceable parts or consumables reported.

Yearly running cost

Not enough data to state a typical yearly figure; the sources report no subscription or consumable cost, and the US box includes the 80W SUPERVOOC charger. A wireless charger is an optional extra.

When it is a good buy

At the $899.99 launch price for 12GB/256GB, the OnePlus 15 undercut the iPhone 17 Pro Max and Samsung Galaxy S25 Ultra by $100-200 while matching or beating them on battery life and charging speed; the 512GB model launched at $999.99 (OnePlus, November 2025). The value is strongest for buyers who prioritize battery life and gaming over cameras. It is no longer available through official US channels as of August 2026, so it now depends on third-party stock. Buyers who prioritize cameras should consider Google or Samsung at similar or slightly higher prices, and the iPhone 17 Pro Max and Galaxy S25 Ultra are the direct alternatives if battery life is not the priority.
