We have done extensive research on the current smartphone market, based on benchmarks, to find more powerful devices than the OnePlus 15. You can read more about our selection process at the end of the article in the methodology section for more details.

Marketed as a gaming phone, the RedMagic 11 Pro was launched in 2025, featuring premium components for fast performance. Like the OnePlus 15, this phone features Qualcomm’s latest high-end Snapdragon 8 Elite Gen 5 chip. However, RedMagic offers a more robust 24GB memory variant along with 12GB and 16GB memory options. For storage, the RedMagic 11 Pro has the same UFS 4.1 storage as the OnePlus 15. According to Antutu benchmarks, the RedMagic 11 Pro beats the OnePlus 15 with a total score of 3,981,427 points compared to 3,621,671.

Based on these numbers, the RedMagic 11 Pro is almost 10% faster, which is huge considering these devices use the same chip. And it’s not just in the total score; The RedMagic beats the OnePlus 15 in every individual category, from CPU to GPU, memory and user experience, and currently tops the Antutu benchmarks as the fastest phone overall. Aside from its fast performance, the RedMagic 11 Pro has a one-of-a-kind liquid cooling system to help the device stay cool at all times.

Other specs include a larger 6.85-inch AMOLED display (with a 144Hz refresh rate, 1,800 nits peak brightness, and 1,216 x 2,688 pixel resolution) and a 7,500mAh silicon-carbon battery with support for 80W wired and 80W wireless fast charging. This phone launched at a starting price of $749, making it even cheaper than the OnePlus 15.

As another phone powered by the Snapdragon 8 Elite Gen 5, the iQOO 15 also stands out for its faster speed than the OnePlus 15. Based on Antutu benchmarks, this phone ranks second overall as the fastest Android phone on the market, beaten only by the RedMagic 11 Pro. With a total score of 3,740,528, the iQOO 15 edges out the OnePlus 15 by over 100,000 points. In Geekbench 6 tests, the iQOO 15 also beats the OnePlus in single-core and multi-core performance despite sharing the same chip.

The iQOO 15 scored 3,477 points in Geekbench’s single-core test and 10,335 in the multi-core test, compared to 3,448 and 10,164 for the OnePlus 15, respectively. It also edges out the OnePlus in Geekbench’s OpenCL and Vulkan tests. This phone pairs the Snapdragon chip with 12GB or 16GB of memory and up to 1TB of UFS 4.1 storage.

On the front of the device is a 6.85-inch 144Hz LTPO AMOLED display with a resolution of 1,440 x 3,168 pixels, which is sharper due to a higher pixel density of 508 compared to the OnePlus 15’s 450 ppi. Additionally, it is also brighter with a peak brightness of 6,000 nits compared to the 1,800 nits from OnePlus. Inside is a 7,000mAh silicon-carbon battery with support for 100W wired and 40W wireless charging. The iQOO 15 has been launched in India starting at Rs 72,999, which is equivalent to around $765.

As you have probably guessed at this point, this is another phone powered by the Snapdragon 8 Elite Gen 5 chip. The Poco F8 Ultra only sells in two variants, one with 12GB memory and 256GB storage and another with 16GB memory and 512GB storage. In terms of performance, the Poco F8 Ultra sits directly above the OnePlus 15 in the Antutu benchmark at the time of writing. The F8 Ultra edges out the OnePlus 15 by scoring an additional 18,680 points, for a total of 3,640,351.

It’s not a huge margin like the RedMagic 11 Pro’s score compared to the OnePlus 15, but it still deserves the bragging rights of offering snappier performance. Interestingly, the OnePlus beats the F8 Ultra in half of the categories (CPU and user experience), but the Poco performs better overall by scoring better in GPU and memory tests.

The Poco F8 Ultra is a flagship phone with a 6.9-inch 120Hz AMOLED display with a peak brightness of 3,500 nits and a resolution of 1,200 x 2,608 pixels. On top of that, you get a triple rear camera setup (a 50 MP wide telephoto lens, 50 MP with 5x optical zoom, and 50 MP ultra-wide), a 32 MP selfie camera, and a 6,500 mAh battery with fast charging support (100W wired and 50W wireless). Poco launched it in the UK in 2025, starting at an MSRP of £749, or around $1,006.

The Realme GT8 Pro is among the few Chinese smartphones more powerful than the iPhone 17. Moreover, this phone also beats the OnePlus 15 in terms of performance. Powered by the Snapdragon 8 Elite Gen 5, the GT8 Pro has solid specs on paper, offering between 12 and 16 GB of memory with a variety of storage options ranging from 256 GB to 1 TB. According to benchmark tests conducted by GSMArena, the GT8 Pro is faster than the OnePlus, having scored 3,666 points in single-core performance in Geekbench 6, slightly higher than the OnePlus’ 3,618 15.

It also came top in GSMArena’s Antutu tests, with 3,873,902 points in version 11, compared to 3,688,274 points for the OnePlus 15. The only test where the OnePlus 15 beats the GT8 Pro is Geekbench’s multi-core test. However, in Antutu v10 as well as 3DMark tests, the Realme GT8 Pro is the faster device. The GT8 Pro sports a 6.79-inch 144Hz AMOLED display (1,440 x 3,136 pixel resolution and 7,000 nits peak brightness), a triple rear camera setup (50 MP wide, 200 MP telephoto, and 50 MP ultra-wide), and a 32 MP selfie camera.

Under the hood, it comes with a 7,000mAh battery supporting 120W wired and up to 50W wireless fast charging speeds. The GT8 Pro was launched in India at a starting price of Rs 72,999 (equivalent to around $765 based on current exchange rate), similar to the iQOO 15.

The OnePlus 15 is a flagship phone with Qualcomm’s latest high-end processor, which makes it powerful. Although many phones are powered by the Snapdragon 8 Elite Gen 5 chipset, not all of them can actually beat the OnePlus 15 in terms of raw performance. Unfortunately, if you’re a buyer looking for the most powerful phone on the market, it’s hard to tell whether a given phone would perform better just by looking at the spec sheet.

Even for our experts whose job it is to keep an eye on these devices, it’s hard to tell some things from specs alone. Fortunately, benchmarks like Antutu and Geekbench provide a standard way to measure the performance of a given device against other smartphones. With that in mind, we relied on Geekbench and Antutu benchmark scores to determine which phones are more powerful than the OnePlus 15.

Price was a secondary factor in our selection process and we have highlighted the MSRP of all devices on the list. When it comes to price, we looked for devices launching with starting MSRPs no more than $200 more or less than the OnePlus 15. Some of these phones aren’t sold in the US, like the Poco F8 Ultra, so you’ll need to expand your search beyond big retailers like Best Buy and Walmart if you want to get your hands on one.
