iQOO 15T launches May 20 with a dedicated ray-tracing chip and an 8000mAh battery
iQOO confirms its 15T gaming flagship will debut on May 20, pairing MediaTek's Dimensity 9500 Monster chipset with a dedicated Q3 e-sports co-processor that the company says is the first mobile chip to support full-scene ray tracing. The phone also packs an 8000mAh battery into an 8.25mm frame — a combination that's unusual even among gaming-focused handsets. The catch: it's launching in China only, with no confirmed US or UK availability.
The Q3 chip claim
The Q3 is a self-developed gaming co-processor that runs independently of the main SoC, handling graphics tasks without leaning on the Dimensity 9500 Monster's GPU. iQOO says the combination delivers 34% better frame stability than its predecessor, and reports TechRadar note the "full-scene ray tracing" claim as a first in mobile. In a controlled benchmark, the phone held 60.2fps for 30 minutes on Genshin Impact at extreme settings while drawing just 4.99W — specific numbers worth treating cautiously until independent testing catches up.
It's worth noting that hardware ray tracing already exists on Snapdragon 8 Elite and Apple's A-series chips. iQOO's "full-scene" qualifier hasn't been tested against those platforms yet, and real gains will ultimately depend on whether game studios optimize for the Q3.
The rest of the spec sheet
The display is a flat 6.82-inch 2K OLED running at up to 144Hz — a direct contrast to competitors like Asus ROG Phone 9 Pro and RedMagic 11 Pro, which have shifted toward 1.5K panels to manage power draw. At 216g and 8.25mm, the 15T is relatively slim for a phone with an 8000mAh cell, though it relies on passive cooling where the ROG Phone and RedMagic use active fans.
The iQOO 15T features a flat 6.82-inch 2K OLED display capable of running select games at 144fps.
Charging tops out at 100W wired. The camera setup includes a 200MP main sensor alongside a 50MP secondary — more substantial than most gaming phones bother with.
What this means outside China
iQOO has no official US or UK distribution channel. If the 15T reaches Western markets at all, it will be through importers and grey-market sellers, likely at £700–800 or $850–950 with no manufacturer warranty. That pricing would undercut the Samsung Galaxy S25 Ultra and iPhone 17 Pro significantly, but those phones come with proven retail support and established ray-tracing implementations. The iQOO 15 (predecessor) was available in Europe through third-party importers at around €646, so the 15T will almost certainly follow the same path — for buyers willing to accept the trade-offs.
