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.

Detailed Comparison

Design & Build

OnePlus 15T

OnePlus inherits the design language of the OnePlus 15 — metal frame, glass back, micro-arc oxidation finish on the rails — and shrinks it into a 6.32-inch, 194g body that's roughly iPhone 17-sized but with more than twice the battery capacity. IP66/IP68/IP69/IP69K rating, ultrasonic fingerprint sensor and ~1.1mm symmetric bezels are unambiguous flagship moves. Reviewers debate whether 6.32-inch genuinely counts as compact in 2026.

Same premium design as the OnePlus 15 — metal frame, glass back, IP69 water resistance — feels high-quality in the hand at just 194g.
Dimensions and weight are similar to an iPhone 17, but the 15T packs more than twice the battery capacity with a ~91% screen-to-body ratio.
Full-level water resistance and a fast ultrasonic fingerprint sensor make the 15T noticeably more confident outdoors than the OnePlus 13T was.
The metal frame uses a micro-arc oxidation process with a 50/50 weight distribution — it doesn't feel top-heavy and one-handed use is genuinely comfortable.

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.
Software-support window is uncertain: OnePlus has not committed to a specific update timeline for the Chinese-market 15T, and the global OnePlus 15 already commits to only 4 years of major Android upgrades — well behind Samsung and Google's 7-year promises.

Poco X7 Pro

What Reviewers Agree On

Flagship-adjacent performance for the money — the Dimensity 8400-Ultra makes it the best-performing phone in its price bracket, beating the Moto Edge 50 and OnePlus Nord 4 (TechRadar, Notebookcheck, Linus Tech Tips, The Tech Chap).
A genuine flagship IP68 water/dust rating despite a sub-£250 starting price — rare at this tier (The Verge, r/Android).
A bright 6.67-inch 1.5K AMOLED, 120Hz, Dolby Vision, ~3,200-nit peak (measured ~1,300 nits auto) with Gorilla Glass 7i — repeatedly called a standout (Linus Tech Tips, The Tech Chap, GSMArena).
A roomy 6,000mAh battery (6,550mAh in India) with 90W charging and the adapter in the box — full charge in ~47–52 minutes (GSMArena, _LExk-yv48I).
A dependable 50MP Sony IMX882 main camera with excellent video stabilization — better than expected for a performance-first phone (r/Android, 38a01oIaeL8).

Deal Breakers

POCO doesn't unlock high frame rates in key games — BGMI is still capped at 60fps nine months on (it could do 120fps), and Asphalt is restricted to 60fps.
The camera system is only adequate beyond the main lens: the 8MP ultrawide and selfie max out at 1080p30 and zoomed/portrait detail drops sharply on digital zoom.
HyperOS is divisive and POCO/Xiaomi aggressively kill background apps to stretch battery — and the active-use battery score is only 'alright, not great' for a 6,000mAh cell.

Display

OnePlus 15T

The 6.32-inch 165 Hz 1.5K AMOLED panel is the only true 165 Hz compact-flagship display on the market and pairs that refresh rate with a measured 1,800 nits brightness, 460 ppi pixel density, Crystal Shield Glass, and HDR10+/Dolby Vision support. Native 165 Hz support in popular FPS games is a real differentiator. Notebookcheck flags 120.7 Hz PWM dimming that can cause eyestrain for sensitive users.

The 6.32-inch 165 Hz AMOLED panel achieves a very good 460 ppi pixel density and the advertised maximum brightness of 1,800 nits in standard measurement.
Display sharpness is plenty competent — sharp, smooth, and easily one of the strongest spec sheets you can get on a compact phone.
Native 165 Hz support in COD, Delta Force and Peacekeeper Elite makes this the only small-screen flagship pushing a full 165 Hz gaming experience.
OnePlus claims up to 3,600 nits peak brightness — even on a playground in direct sunlight you can still see everything clearly, no squinting required.
Specifications confirm a 6.32-inch 1.5K (1216 × 2640) resolution with 165 Hz refresh — a configuration unique to the 15T in the compact class.
Display backlight flickers at just 120.7 Hz under PWM dimming — low enough that the flickering may cause eyestrain and headaches for sensitive users after extended use.

Poco X7 Pro

A 6.67-inch 1.5K AMOLED that punches well above its price on brightness and smoothness.

The 6.67-inch 1.5K AMOLED with 120Hz adaptive refresh and ~3,200-nit peak is one of the X7 Pro's standout features — crisp visuals and smooth scrolling.
Measured ~700 nits at manual brightness and over 1,300 nits with auto-brightness, with 4K 60fps HDR video playing perfectly.
Official panel specs: 700 nits typical, 1,400 nits maximum, 3,200 nits peak, 120Hz, Dolby Vision and HDR10+.

Battery & Charging

OnePlus 15T

This is the section the OnePlus 15T was built to win. The 7,500 mAh silicon-carbon 'Glacier' cell is the largest ever fitted to a true compact phone — 50% bigger than the iPhone 17's pack in a similar footprint. Notebookcheck measured roughly 1.5 days of real-world endurance at 150 cd/m². Wired charging tops out at 100 W, wireless at 50 W. The only friction points are the missing built-in magnets for MagSafe-style alignment and the still-USB-2.0 port.

OnePlus relies on a silicon-carbon-based battery with a large capacity of 7,500 mAh for its mini flagship — in our practical battery test at 150 cd/m² brightness, the 15T achieved an excellent battery life of nearly 1.5 days.
9to5Google's preview confirms the 7,500 mAh cell carries the same 'Glacier' moniker as the OnePlus 15's battery, so the silicon-carbon structure is here too — 200 mAh more than the larger sibling.
Even though the phone keeps the same compact size, it now packs a massive 7,500 mAh battery — to put that into perspective, the iPhone 17 Pro Max only has around 5,000 mAh, and this is a 6.32-inch phone.
Battery life is wild for a phone this size and is actually a hair bigger than the one in the OnePlus 15, which has a noticeably larger footprint.
100W SuperVOOC wired charging and 50W wireless mean even the huge cell refills fast — getting through two full days on a single charge feels totally realistic.
There is no native magnetic Qi alignment — wireless charging works, but accessories require a separate magnetic case for MagSafe-style snap-on functionality.
r/Android's reaction to the battery is unambiguous — 'Incredible battery life makes the compact smartphone competition pale in comparison' is the actual review-thread headline.

Poco X7 Pro

A roomy 6,000mAh cell (6,550mAh in India) with fast 90W charging and the brick in the box — endurance that's good in daily use but debated under heavy load.

Real-world daily use returns 9–11 hours of screen-on-time and ending the day with 20–30% left, plus 15+ hours of video playback.
90W charging (adapter in box; any 90W+ USB-PD works) reaches 50% in ~18–22 minutes and a full charge in ~47–52 minutes.
GSMArena's active-use score of 12h43m is described as 'alright, but not great, considering the battery capacity.'
POCO/Xiaomi aggressively kill background apps to extend battery life — a long-standing annoyance that still affects background-running apps even with optimisation off.
Fast charging measured as not degrading battery health — a phone tracked at 4 months / 132 cycles still showed 99% battery health.
