There's more to this flagship killer than its humongous 7,300 mAh battery.
Just before the launch, the OnePlus Club posted the anticipated specs of the new device in comparison to the previous model on X:

Let's examine the details to determine the advantages and disadvantages.
Processing Prowess
The Snapdragon 8 Elite Gen 5 powers the OnePlus 15, which should make it a performance leader among Android phones by the end of 2025. The OnePlus 13, with its Snapdragon 8 Elite, was also impressive, but the updated chipset should make the new phone faster and more power efficient.
Large Battery Capacity
A substantial 7,300 mAh battery powers the OnePlus 15.
This is a notable spec. With such a large battery, users should get extensive usage for videos, gaming, and demanding applications without being concerned about power drain.
Rapid Charging Capabilities
The OnePlus 15 boasts 120W fast charging, a boost from its predecessor's 100W. While some may view this as a minor improvement, OnePlus should be recognized for increasing charging speed by 20% over the already fast 100W.
Slightly Smaller, Faster Display
The OnePlus 15 features a 6.78-inch display, which is slightly smaller than the 6.82-inch screen of the previous model. However, the refresh rate is increased to 165Hz. While some believe anything above 120Hz is unnecessary, gamers are likely to appreciate this upgrade. Note that the display resolution decreases from 2K to 1.5K.
Next-Gen Display Technology
According to the OnePlus Club, the OnePlus 15 uses BOE X3 display material, a change from the BOE X2. As a result, the OnePlus 15 has extremely thin 1.15 mm bezels for a more engaging experience. The custom BOE X3 panel is expected to provide 30% greater durability, lower power consumption, and enhanced brightness and color accuracy compared to its forerunner. OnePlus' custom Display P3 chipset will manage consistent brightness and can dim to 1-nit for comfortable nighttime viewing.
Flat Display Design
Users who dislike curved screens will enjoy using the OnePlus 15. The latest model abandons the OnePlus 13's quad-curved display in favor of a flat, stylish, and robust design.
Larger Main Camera Sensor
The OnePlus 15 should appeal to photographers who frequently use the primary camera, due to its larger 50 MP sensor, increasing from 1/1.56" to 1/1.4".
A larger sensor gathers additional light, improving image quality, especially in dim environments. It also provides enhanced depth of field control, giving images a more professional appearance with blurred backgrounds. Larger sensors typically produce clearer, more detailed images with less noise.
Improved Telephoto Lens
The updated 50 MP 3x telephoto lens now offers a 3.5x magnification. The OnePlus 13 had a 73 mm equivalent focal length, whereas the OnePlus 15 has an 85mm equivalent.
This lets users get closer to their subjects while preserving clarity, making it ideal for portraits or capturing distant objects. The longer focal length also offers better background compression for more visually appealing photos. The enhanced telephoto lens adds versatility, allowing users to capture high-quality zoomed shots without sacrificing sharpness or image quality.
End of Hasselblad Partnership
The OnePlus 13 is likely the last OnePlus flagship to feature a camera system co-developed with Hasselblad, as the OnePlus 15 introduces the DetailMax Engine.
The main question is whether DetailMax can surpass the performance of the Hasselblad collaborations and impress mobile photography enthusiasts. Its success depends on its ability to combine technical precision with real-world usability, producing professional-quality images that are easily achievable on a smartphone. If successful, DetailMax could redefine expectations for flagship mobile cameras.
Alert Slider Removed
The removal of the signature Alert Slider may be seen negatively by some longtime OnePlus fans. The OnePlus 15 replaces it with the new Plus Key, which users can customize to carry out different functions. However, many people loved the slider.
Pricing and Availability
We will update this post as soon as OnePlus releases the details, so check back often.
Overall, the OnePlus 15 appears to be an excellent flagship phone. Will you buy this smartphone?
