OnePlus is cooking up something big—literally. Leaks suggest that the next OnePlus Ace smartphone, likely named the OnePlus Ace 5S, will come with a huge 6.83-inch display, the upcoming Dimensity 9400+ chip, and a massive battery that could reach 7,500mAh. If true, this could be one of the most power-packed phones of 2025.
Big, bright & smooth: 6.83-inch OLED display
The OnePlus Ace 5S is rumored to feature a 6.83-inch flat LTPS OLED display with a 1.5K resolution and a 120Hz refresh rate. That means sharp visuals, deep blacks, and buttery-smooth scrolling—all the good stuff we expect from a high-end OnePlus screen.
Dimensity 9400+—Next-level performance incoming?
Under the hood, this beast could debut MediaTek’s Dimensity 9400+, a slightly overclocked version of the Dimensity 9400, expected to launch on April 11. If these rumors hold up, we’re looking at a serious upgrade in AI-driven performance, gaming capabilities, and overall efficiency. Expect faster app launches, better multitasking, and top-tier gaming performance.
First in its class
Here’s where things get wild. Early reports suggest the Ace 5S could pack a 7,000mAh battery, but some sources claim OnePlus is still debating whether to push it to 7,500mAh. If that happens, this would be one of the largest batteries ever in a mainstream phone.
But there’s a catch. Instead of the 100W or 120W fast charging we’ve seen on some previous OnePlus devices, this model might cap out at 80W charging. Still fast, but a step down. It seems like OnePlus is prioritizing battery life over crazy-fast charging speeds.
Less is better?
The camera setup is said to feature a 50MP primary sensor, but don’t expect a telephoto lens. This suggests OnePlus is focusing on quality rather than unnecessary extra sensors.
As for the design, leaks indicate that OnePlus might ditch the circular camera module from previous models and go for something more minimalist and clean. Another possible shake-up? The beloved Alert Slider might be gone, replaced by a new ‘Magic Cube’ button—a customizable shortcut for various functions.
OnePlus Ace 5S poised to be the new battery king?
If these leaks are accurate, the OnePlus Ace 5S could be a battery champion, giving power users and gamers a phone that lasts far longer than most flagships. The Dimensity 9400+ and massive display make it a performance beast, though we’ll have to wait and see how OnePlus balances weight, thickness, and charging speeds.
The big question: Would you trade ultra-fast charging for a monster battery?
