OnePlus 15T vs Poco F7 Ultra

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 F7 Ultra

A 6.67-inch 2K 120Hz AMOLED that's bright, color-accurate and a clear generational upgrade.

• GSMArena measured 1,506 nits under standard test conditions — plenty bright and a clear improvement over the F6 Pro.
• A 2K 120Hz AMOLED with 3,200-nit peak brightness — r/Android calls it 'excellent, bright, Dolby Vision-compliant.'
• Independent testing logged ~3,200-nit peak and ~1,800 nits in high-brightness mode, with a 1.91-nit minimum and 3,840Hz PWM dimming for night use.
• In a side-by-side it was visibly brighter than a Samsung flagship in harsh outdoor light, despite costing half as much.

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 F7 Ultra

A modest 5,300mAh cell offset by the fastest charging in its class — 120W wired and Ultra-exclusive 50W wireless.

• 120W wired charging fully refills the 5,300mAh battery in ~30 minutes (60% at the 15-minute mark); a 90W adapter is only marginally slower.
• Adds 120W wired plus 50W wireless charging — faster than anything out there including the S25 Ultra, and wireless charging is exclusive to the Ultra in the F7 line.
• The F7 Pro carries a larger 6,000mAh battery vs the Ultra's 5,300mAh, but real-world battery-life difference between them is minor.
• Endurance results vary widely by test — one rundown hit an 'insane' 35h27m, while a standardized 1440p test got only ~14h22m, behind a smaller-battery S25 Ultra.
• In a six-flagship drain test it lasted 6h18m of active screen-on time — mid-pack, behind the iPhone, OnePlus and Vivo X200 Pro but ahead of the Xiaomi 15.
