| The OnePlus 13s. |
Following the global announcement of the OnePlus 15 and confirmation of the OnePlus 15R, the lineup seems poised for a third contender. Fresh leaks now point to an upcoming OnePlus 15s, a device that aims to blend high-end performance in a more compact frame, potentially succeeding the OnePlus 13s from earlier this year.
According to a detailed leak from the known source @OnePlusClub on X, the OnePlus 15s is shaping up to be anything but a "mini" compromise. For enthusiasts who prefer phones that fit comfortably in one hand without sacrificing power, this could be the 2026 release to watch.
The leak, which you can view here, provides a comprehensive early look at what OnePlus might be planning.
Display: Flagship Quality in a Compact Size
The leak suggests the OnePlus 15s will feature a 6.31-inch OLED panel, striking a balance between screen real estate and manageable size. Crucially, it’s rumored to boast a 1.5K resolution and an ultra-smooth 165Hz refresh rate. Even more impressive is the claimed use of the BOE X3 panel, the same technology found in the flagship OnePlus 15. This indicates that users won't have to settle for inferior display quality despite the smaller form factor.
Performance: No Compromise on Power
Under the hood, the OnePlus 15s is tipped to be an absolute beast. It’s expected to be powered by the Snapdragon 8 Elite Gen 5, Qualcomm's latest and greatest processor. This aligns it directly with the most powerful Android phones on the market, suggesting OnePlus is positioning the "s" model as a true compact flagship for performance purists, rather than a mid-tier option.
Camera: A Focused, High-Resolution Setup
The camera system appears to follow a distinct philosophy. The primary sensor could be either a 50MP Sony IMX906 or a massive 200MP Isocell HP5. For zoom capabilities, OnePlus may again utilize a 50MP Samsung JN5 sensor, touted to offer up to 50X digital zoom.
Notably, the leak indicates the OnePlus 15s might continue the trend set by its predecessor by omitting an ultrawide camera. The OnePlus 13s featured a dual-camera setup with a 50MP main and a 50MP telephoto, and the 15s could adopt a similar, focused approach prioritizing primary and zoom photography over an ultrawide lens.
Battery & Charging: Surprisingly Massive Capacity
Perhaps the most shocking leak is the battery specification. Despite its smaller size, the OnePlus 15s is rumored to pack an enormous approximately 7,500mAh battery. For context, the larger OnePlus 15 is said to house a 7,300mAh cell. This would be a monumental capacity for a compact phone, potentially offering exceptional battery life.
Supporting this large battery will be 100W or 120W wired fast charging. However, to possibly differentiate it from the Pro models or manage thermal constraints, wireless charging support might be absent.
Pro Tip: To fuel such rapid charging speeds, you'll need a powerful charger. A reliable option like the 145W Ugreen 25K power bank (currently on sale for $65 on Amazon) would be a perfect companion for on-the-go top-ups. Check it out here.
A Word of Caution & Expected Launch
It’s important to stress that these specifications are unofficial and based on early leaks. Final product details could vary as development continues. Given that the OnePlus 13s launched in June 2025, a logical timeline would place the OnePlus 15s debut around mid-2026.
If the leaks hold true, the OnePlus 15s could disrupt the compact phone market by offering a no-compromise spec sheet—flagship processor, elite display, huge battery, and super-fast charging—all in a hand-friendly size. It’s a formula that could appeal powerfully to users tired of ever-growing phones.
