Two-day battery and the fastest chip in Android, for hundreds less.

OnePlus 15

OnePlus

A 7,300 mAh battery, an 80W brick in the box, and Snapdragon 8 Elite Gen 5 make this the endurance-and-speed champion — at $899, hundreds under the S26 Ultra. The camera is good-not-great post-Hasselblad and updates lag rivals. Buy it for battery and power, not photos.

The OnePlus 15 is built around two numbers: 7,300 and 8 Elite Gen 5. The battery is the first 7,000-plus mAh cell in a global flagship — a silicon-carbon pack that genuinely stretches to two days of normal use — and it refills at 80W from the included charger, something Samsung and Apple still make you pay extra for. The chip is Qualcomm's fastest; in Techsponential's benchmarks it matched the iPhone 17 Pro on single-core and beat it on multi-core, with a hand-tearable steel vapor chamber keeping it cool through long gaming sessions at a locked 120fps on a 165Hz screen. The camera is where the compromise lives. With the Hasselblad partnership over, OnePlus leans on its own DetailMax processing across a triple 50MP array. Daylight shots are sharp with natural color and the new autofocus selfie camera is a real upgrade, but low-light realism still trails Apple, Samsung, and Pixel. The display also drops to a 1.5K panel — fast and bright, but less crisp than the 2K screens on pricier rivals. Two more things to weigh: software updates don't match Samsung's or Google's seven-year commitments, and a recent OxygenOS update was pulled after bricking some phones. It's also direct-purchase only in the US, with no carrier deals. None of that changes the core proposition — nothing else near $899 lasts this long or runs this fast.
