Design & Display
When comparing OnePlus 15 vs Samsung Galaxy S25 in design, the OnePlus 15 is set to adopt a square camera module (moving away from circular), along with a nano-ceramic metal frame for enhanced durability. Rumors hint at a flat front and back, giving it a bold and premium feel.
On the other hand, the Galaxy S25 retains a more compact form factor with an aluminum frame and classic triple camera arrangement. Its 6.2-inch Dynamic AMOLED display offers vivid colors and the smoothness of 120 Hz refresh rate, though the OnePlus 15’s rumored 165 Hz panel could raise the bar.

Camera Performance
Camera systems are among the most scrutinized features. In this face-off of OnePlus 15 vs Samsung Galaxy S25, OnePlus appears to wager heavily on optics:
- OnePlus 15 may employ a tri-lens setup with equal 50 MP sensors (main, ultra-wide, periscope). That promises consistency in output across focal lengths.
- Galaxy S25 uses a more traditional layout: 50 MP main, 12 MP ultra-wide, and 10 MP telephoto for 3× zoom. The lower MP values for secondary lenses may mean less detail in certain scenarios.
In selfie capture, the OnePlus 15 vs Samsung Galaxy S25 contrast is stark: OnePlus is rumored to push 32 MP upfront, while Samsung offers only 12 MP. If real, OnePlus could dominate the self-portrait arena.
However, real-world performance will depend heavily on image processing, software optimization, and sensor hardware beyond MP counts.
Performance & Battery
In the showdown OnePlus 15 vs Samsung Galaxy S25, performance and battery life are critical differentiators.
- Processor & Memory: The OnePlus 15 is expected to be equipped with the Snapdragon 8 Elite Gen 5 paired with up to 16 GB RAM, providing future-proof muscle. The Galaxy S25 uses a previous-generation Snapdragon 8 Elite plus 12 GB RAM — still powerful, but potentially a step behind.
- Battery & Charging: The OnePlus 15 is rumored to include a massive ~7,300 mAh battery supporting 120 W fast charging. In contrast, the Galaxy S25 has just a 4,000 mAh cell and supports only 25 W charging. The OnePlus 15 vs Samsung Galaxy S25 contrast favors OnePlus heavily in endurance and recharge speed.
From a long-session usage perspective—gaming, streaming, multitasking—OnePlus likely holds the advantage in this metric.
Price & Value
One of the most important axes in OnePlus 15 vs Samsung Galaxy S25 is value. The rumored starting price of the OnePlus 15 in India is ~Rs. 75,000, whereas the Galaxy S25 begins at ~Rs. 80,999. That gives OnePlus a pricing edge even before factoring in promotions and discounts.
Given its specs and features, if the OnePlus 15 stays near that price range, it could deliver better bang for buck compared to the Galaxy S25.
