What Reviewers Agree On

Grade-5 titanium frame drops weight to 187g (~19g lighter than 14 Pro) — most-praised in-hand feel of any small flagship
Same A17 Pro 3nm chip with hardware ray tracing, 8GB RAM, NVMe — same performance as the $200-more Pro Max
Same USB-C 3.0 (10Gbps), Action Button, ProMotion 120Hz, 2000-nit peak as the Pro Max — Pro features in a compact body
Same Apple Intelligence support on iOS 18+ — future-proofs through iOS 23+ in 2030s
Genuinely pocketable 6.1-inch flagship — increasingly rare in a 6.7"+ Pro-Max-dominant market
WIRED 8/10 — 'iPhone 15 Pro is the small Pro that finally tempts large-Pro owners'

Detailed Comparison

Performance

iPhone 15 Pro

Same A17 Pro 3nm chip with hardware ray tracing, 8GB RAM and NVMe storage as the Pro Max. Apple Intelligence on iOS 18+ requires this chip. Launch overheating issues real but largely fixed via iOS 17.0.3.

A17 Pro 3nm with 8GB RAM and NVMe storage — fastest mobile silicon at launch, identical to the Pro Max.
Apple Intelligence support on iOS 18.1+ — A17 Pro is the minimum chip required, future-proofs the phone.
Hardware ray tracing enables console-grade ports: Resident Evil 4, Death Stranding, Assassin's Creed Mirage run natively.
Launch overheating: A17 Pro ran hot in gaming and 4K shoots; iOS 17.0.3 mitigated but didn't fully eliminate — affects the smaller Pro slightly more due to thermal headroom.
In 2025, A17 Pro remains an absolute performer for everyday + intensive use — aged extremely well.

OnePlus 15T

What Reviewers Agree On

The 7,500 mAh silicon-carbon 'Glacier' battery is unprecedented in a 6.32-inch body and delivers roughly 1.5 days of real-world endurance — easily the longest battery life in the compact-flagship class.
Build quality is genuine flagship-grade: metal frame, IP66/IP68/IP69/IP69K dust + water resistance, ultrasonic in-display fingerprint sensor, and a 91% screen-to-body ratio with ~1.1 mm symmetric bezels.
The 6.32-inch 165 Hz 1.5K AMOLED reaches the advertised 1,800 nits in standard measurement and is marketed up to 3,600 nits peak — making it the only true 165 Hz compact-flagship display on the market.
Snapdragon 8 Elite Gen 5 + 16GB LPDDR5X Ultra Pro RAM hits Geekbench multi-core ~10,976 and 3DMark Wild Life Unlimited ~29,901 — top-tier flagship synthetic performance in a sub-200g chassis.
100W wired SuperVOOC and 50W wireless charging mean even the giant battery refills fast.
The new 3.5x periscope telephoto with OIS is a meaningful step up from the OnePlus 13T's limited 2x zoom and is well-suited to portraits at the classic 85 mm focal length.

Deal Breakers

China-only launch with no confirmed global release — ColorOS instead of OxygenOS, no eSIM support, no WearOS support, and missing European LTE band 20 and band 32 make it a compromise outside China.
Notebookcheck measured pronounced sustained-performance throttling of over 50% in 3DMark stress tests, with surface temperatures climbing past 46 °C; SuperSaf hit 50 °C on the back during Wildlife Extreme and saw scores drop from 6,990 to 3,743 inside a single loop.
No ultrawide camera at all — the 'triple camera' is just main + 16MP front + 3.5x periscope telephoto, which is a downgrade versus the OnePlus 15 for anyone who shoots landscapes, group photos or wide-angle video.
Charging port is still USB 2.0 in 2026, which SuperSaf calls 'a choice and not a good one' on a flagship-tier device at this price.
No built-in MagSafe-style magnets — wireless-charging accessories require a separate magnetic case to align properly.

OnePlus 15T

Snapdragon 8 Elite Gen 5 paired with 12-16GB LPDDR5X Ultra Pro RAM delivers flagship synthetic scores — Notebookcheck recorded Geekbench multi-core 10,976 and 3DMark Wild Life Unlimited 29,901, on par with the larger Xiaomi 17 and Honor Magic8 Pro Air. The problem is sustained: in the 3DMark Wild Life stress test the GPU drops over 50% and the back of the phone hits 50 °C, which both Notebookcheck and SuperSaf flag as a deal-breaker for long gaming sessions.

Geekbench 6 multi-core hits 10,976 — flagship-tier and within 1% of the average 8 Elite Gen 5 result, so there is no compromise on the chipset versus larger phones.
3DMark Wild Life Unlimited hits 29,901 — 5% above the 8 Elite Gen 5 average and ahead of the Xiaomi 17 with the same chip.
In the 3DMark stress tests the OnePlus 15T shows a sharp drop in performance of over 50%, which significantly lowers our rating.
Wildlife Extreme stress test scores swung from 6,990 best loop to 3,743 worst loop in a single run — the chart is 'quite a bit of a bumpy ride' and performance mode did nothing to stabilize it.
Surface temperatures hit 48.3 °C on the back during stress testing and continued climbing to 50 °C near the camera bump — about 45 °C internal — which seems to be the phone's thermal limit.
Genshin Impact averaged 60.3 fps over 30 minutes at just 3.2 W power draw, with the phone staying cool to the touch — and Peacekeeper Elite pushed 164.5 fps thanks to native 165 Hz support.
r/Android's reviewer thread flags the same thermal issue directly: 'Gets kinda hot, over 50 degrees in the corner. This is with its very heavy throttling.'
