Display
When you spend hours looking at your phone, the display becomes a key factor. The Poco X8 Pro Max comes with a 6.83-inch 1.5K ultra-bright AMOLED display with a 120Hz refresh rate, which makes scrolling and animations feel smooth and responsive. It’s particularly easy to see outdoors thanks to the extra brightness.
The OnePlus 15R also has a 6.83-inch 1.5K AMOLED screen but with a variable refresh rate from 60Hz to 165Hz. This adaptive feature helps save battery during simple tasks while delivering buttery-smooth motion when gaming or scrolling. The OnePlus screen also includes 3840Hz PWM + DC dimming to reduce eye strain and is protected with Gorilla Glass 7i.
If you prioritize extreme smoothness and adaptive refresh, the OnePlus 15R pulls ahead, but the Poco X8 Pro Max’s brightness makes it excellent for outdoor use.

Performance
Time to talk about the processor of the Poco X8 Pro Max vs OnePlus 15R. Performance determines how snappy your phone feels in daily life and how well it handles demanding apps. The Poco X8 Pro Max runs on the MediaTek Dimensity 9500s processor paired with 12GB of LPDDR5X RAM at 9600Mbps. It’s fast enough for gaming, multitasking, and streaming. The OnePlus 15R, however, is powered by the Snapdragon 8 Gen 5 with Adreno 840 graphics and UFS 4.1 storage.
This combination gives you slightly faster app load times, smoother high-end gaming, and future-proof performance for the next few years. In everyday use, both phones handle apps effortlessly, but if you want the top-of-the-line power for gaming or heavy multitasking, the OnePlus 15R is the better choice.
Battery
Let us now compare the battery between the Poxo X8 Pro Max vs OnePlus 15R. The Poco X8 Pro Max boasts a massive 8500mAh battery, which is one of the largest on the market in 2026. It easily lasts a full day and beyond, even if you game or watch videos for hours. It also supports 100W HyperCharge, which can fill up the battery quickly when needed.
The OnePlus 15R has a smaller but still very capable 7400mAh battery with 80W SuperVOOC charging. You’ll comfortably get through a full day, but the Poco X8 Pro Max will give you extra hours before needing a charge. If battery life is your top priority, the Poco is the clear winner.
Camera
Your phone’s camera plays a big role in capturing memories. The Poco X8 Pro Max comes with a 50MP main camera and an 8MP ultra-wide lens, while the front-facing camera is 20MP with autofocus, capable of recording 4K video.
The OnePlus 15R has a 50MP main camera with optical image stabilization (OIS), an 8MP ultra-wide, and a 32MP front camera capable of 4K 30fps video. OIS makes the OnePlus 15R especially better for low-light photography and steady video capture.
If you take a lot of selfies or videos, the higher-resolution front camera and OIS give the OnePlus 15R a slight edge over the Poco X8 Pro Max.

Software
Software shapes your daily experience with a phone. The Poco X8 Pro Max runs Android 16 with Xiaomi’s HyperOS 3, offering customization, themes, and extra features. OnePlus 15R also runs Android 16 but with OxygenOS 16, which focuses on clean design, smooth animations, and minimal bloatware.
If you enjoy tweaking settings and themes, HyperOS is appealing, but if you want a sleek and simple interface that “just works,” OxygenOS is more user-friendly. Many users find OxygenOS slightly more refined, giving the OnePlus 15R a small advantage.
Connectivity
Modern smartphones rely on connectivity features to stay connected and versatile. Both the Poco X8 Pro Max and OnePlus 15R support 5G, Wi-Fi 7, and Bluetooth 6.0. The Poco supports dual-band GPS and USB-C 2.0, while the OnePlus adds multi-GNSS support and NFC, which is handy for contactless payments and public transit.
If you use NFC or travel frequently, the OnePlus 15R offers slightly better connectivity options.
