OnePlus 13 vs. Samsung Galaxy S25 Ultra: The Verdict
When two flagship smartphones go head-to-head, the decision comes down to what matters most to you. Is it the camera? Battery life? Or maybe the display? Let’s break it down quickly so you can decide whether the OnePlus 13 or Samsung Galaxy S25 Ultra fits your needs.
Battery Life
The OnePlus 13 offers blazing-fast 150W charging, fully juicing up its 5,000mAh battery in under 20 minutes. On the other hand, Samsung’s Galaxy S25 Ultra takes it slow at 45W but makes up for it with stellar power efficiency, lasting slightly longer on a single charge.
Winner: OnePlus 13 (for its unbeatable charging speed)
Camera
Samsung takes the crown here with its 200MP main sensor and jaw-dropping 100x Space Zoom. If photography is your thing, the S25 Ultra won’t disappoint. The OnePlus 13, while solid, doesn’t quite match the same level of versatility.
Winner: Samsung Galaxy S25 Ultra
Display
Both phones boast top-notch screens. The OnePlus 13’s 6.7-inch OLED display is stunning and responsive, but Samsung’s 6.9-inch Dynamic AMOLED 2X edges it out with brighter colors, better HDR, and adaptive refresh rates for efficiency.
Winner: Samsung Galaxy S25 Ultra

Design & Build Quality
The OnePlus 13 screams minimalism with its sleek, no-nonsense design. Its aluminum frame and matte finish feel modern and durable. Meanwhile, Samsung’s S25 Ultra takes the “go big or go home” approach. Its bold, slightly boxy design might not suit everyone, but the Gorilla Glass Victus 3 protection adds a sense of indestructibility. Both phones feel premium, but the Galaxy S25 Ultra’s curved edges and heft may be divisive—you either love it or you don’t.
Winner: OnePlus 13 (for its simpler, more universally appealing design)
Display
The OnePlus 13 features a stunning 6.7-inch OLED screen with a 2K resolution and a buttery-smooth 120Hz refresh rate. It’s a joy to watch Netflix or scroll endlessly on TikTok. However, Samsung has doubled down with its monstrous 6.9-inch Dynamic AMOLED 2X display. It’s brighter, more vibrant, and offers a slight edge when it comes to HDR content. Plus, Samsung’s adaptive refresh rate tech can drop down to 1Hz, which means better efficiency.
Winner: Samsung Galaxy S25 Ultra
Camera
This category is where the Galaxy S25 Ultra flexes its muscles. With its 200MP main sensor and jaw-dropping zoom capabilities (up to 100x!), it’s the phone for anyone obsessed with photography. Whether you’re snapping cityscapes or trying to capture the moon, Samsung delivers.
The OnePlus 13, on the other hand, focuses on consistency. Its 50MP main sensor takes vibrant, true-to-life shots, and its Hasselblad partnership shines in color science. But it doesn’t quite match Samsung’s versatility, especially in low-light or zoom performance.
Winner: Samsung Galaxy S25 Ultra
Battery Life
Both phones offer impressive battery performance. The OnePlus 13 packs a 5,000mAh battery with lightning-fast 150W charging, meaning you can go from 0 to 100% in under 20 minutes. Samsung also equips the S25 Ultra with a 5,000mAh battery, but its charging speed maxes out at 45W. It does, however, boast slightly better optimization, squeezing out an extra hour or two of screen-on time.
Winner: OnePlus 13 (if charging speed matters)
Performance
Powered by the Snapdragon 8 Gen 4 chipset, both devices are insanely fast. Whether you’re gaming, multitasking, or editing videos, they won’t let you down. The S25 Ultra edges out slightly with its heat management, which keeps performance consistent even under heavy loads.
Winner: Samsung Galaxy S25 Ultra (barely)
Price
Price might just be the deciding factor for many. The OnePlus 13 starts at $899, making it a flagship that doesn’t break the bank. Samsung’s S25 Ultra starts at $1,299, which might feel steep unless you need all the extra bells and whistles.
Winner: OnePlus 13
