New leaks suggest that upcoming OnePlus Ace 6 might outperform even its flagship sibling, the OnePlus 15, in certain areas. With massive batteries, record-breaking displays, and contrasting priorities, these two smartphones are shaping up to redefine OnePlus’s 2025 strategy.
OnePlus 15 vs Ace 6 Design Comparison
OnePlus is unifying its 2025 design language across models. Both the OnePlus 15 and Ace 6 sport flat OLED panels and a new corner camera island that replaces the older circular module. The Alert Slider, a OnePlus hallmark, is gone replaced by a Plus Key on the 15 and removed entirely on the Ace 6.
The OnePlus 15 embraces premium materials. It features a nano-ceramic coated metal frame and a fiberglass back on the “Sand Storm” edition, combining a luxury look with better durability. The Ace 6 (expected to launch globally as the OnePlus 15R) trades luxury for toughness it’s IP66, IP68, and even IP69K certified, the highest water-resistance rating ever seen on a OnePlus phone.
