Detailed Comparison

Design & Build

Oppo Find X9 Pro

Premium flat-sided slab design with a perfectly flat screen and back, slim at 8.25mm despite the massive 7,500mAh battery. IP68/IP69 water resistance and Gorilla Glass Victus 2 protection. Some reviewers find the design "safe" and lacking personality, especially with conservative color options.

Impressively slim at 8.25mm despite housing a class-leading 7,500mAh battery
IP68/IP69 water resistance with Gorilla Glass Victus 2 — genuinely durable build
Symmetrical narrow bezels create an immersive, modern look
Design described as "safe" and "boring" with conservative color options lacking personality

Samsung Galaxy S25+

The S25+ features a sleek, refined design with flat edges and Gorilla Glass Victus 2 on both sides. While not dramatically different from the S24+, it's slightly thinner and lighter, earning praise for its premium feel.

The flat-edge design gives it a more modern, premium look compared to previous generations

Battery Life

Oppo Find X9 Pro

Record-breaking battery life. The 7,500mAh silicon-carbon battery delivered the highest endurance score GSMArena has ever recorded — nearly 22 hours of active use. PhoneArena called it the best battery life tested in two years. This is easily a 2-day phone that can approach 3 days with conservative use. 80W wired and 50W wireless charging complete the package.

GSMArena Active Use Score of 21:57 hours — the highest ever recorded by the publication
PhoneArena: best battery life tested in the past two years — 25.5 hours web browsing, easily a 2-3 day phone
80W wired charging fills 0-100% in approximately 45 minutes with 50W wireless charging support

Samsung Galaxy S25+

The 4,900mAh battery comfortably lasts a full day for most users, with the Snapdragon 8 Elite's efficiency helping extend endurance. Charging speeds remain adequate but not class-leading.

Battery easily lasts a full day with moderate to heavy use — a noticeable improvement over the S24+
45W wired charging gets you to 65% in 30 minutes, which is competitive but not the fastest
15W wireless charging and reverse wireless charging round out the charging options
