Compact battery champion

The best small Android flagship

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.

Samsung Galaxy S24
A compact, flat-sided 6.2-inch body with rounded corners and an aluminium frame — easy to use one-handed and still feels sturdy years later.
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.
Samsung Galaxy S24
A 6.2-inch FHD+ Dynamic LTPO AMOLED 2X at 120Hz, jumping to a 2,600-nit peak (up from the S23's 1,750). Small but excellent.
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.
Samsung Galaxy S24
A 4,000mAh cell (up from the S23's 3,900) with markedly better endurance — but charging is still capped at an unchanged 25W.
