OnePlus 15R review: A 165Hz display and big battery for $700

I know what you're thinking, didn't OnePlus release a new phone just last month? It did. A little over five weeks after the announcement of the OP15, the company is back with the OnePlus 15R, a more affordable version of its new flagship that starts at $700 (or $200 less than its sibling). Off the top, this will be a shorter review because most of what I said about the OnePlus 15 also applies to the OP15R. It's a great phone that asks you to make one pretty significant compromise.

Like the OnePlus 15, the 15R looks like the OnePlus 13s and 13T, a pair of smaller, 6.32-inch phones the company released in India and China this past spring. I said the design of the OP15 was boring and derivative of the iPhone 16 Pro. The 15R has done nothing to change that opinion. With one fewer camera, the OP15R doesn't look much different from the iPhone 12 I've been hanging on to since 2020. 

That said, I'm more fond of the 15R's mint breeze color (the phone is also available in charcoal black) than the sand storm shade of my OP15. We're big fans of minty phones here at Engadget, and OnePlus has gone with a particularly pleasing hue of the color with its new phone. With the redesign, OnePlus has also improved the phone's waterproofing, bringing it in line with the OP15. The new handset is IP69K-certified against moisture and dust, meaning it can withstand heated water shot at it at pressure. Like the OP15, the 15R trades OnePlus' old Alert Slider for a new Plus Key. It functions like the iPhone's Action button, allowing you to add a shortcut for a favorite feature. For example, you can configure it to open the camera app or act as a do not disturb toggle, among a few other options.  

One departure from the OP15 is that the 15R has a larger 6.83-inch display, making it slightly taller than its sibling. OnePlus is marketing this as one reason buyers might pick the 15R over the OP15, but holding the phones side by side, there's not much difference between the two. They're both big, and you'll either like that or won't.

On top of being big, the 15R's screen can refresh at a fast 165Hz in games. The two displays are also comparable in terms of resolution and brightness; both can push 1,800 nits of brightness. One difference I noticed is the OnePlus 15 has a warmer panel, even when the two phones are set to the same colorspace. I've reached out to OnePlus to find what might be causing the disparity, but for now it may be due to a quality control issue or oversight in the company's software.  

One last thing, OnePlus has upgraded the 15R to add an ultrasonic fingerprint sensor beneath the screen. This is placed in a nice spot toward the bottom third of the display, and it's fast and accurate.   

Performance and battery

The OnePlus 15R is the first phone in North America to arrive with Qualcomm's latest Snapdragon 8 Gen 5 chipset. Not to be confused with the Snapdragon Gen 5 Elite in the OP15, this new chipset is similar to Qualcomm's flagship system-on-a-chip but has a weaker CPU and GPU. This is reflected in benchmarks like Geekbench 6 where the OP15 handily outperforms the OP15R. It's not even close, either, with the OP15 delivering standout single- and multi-core scores of 3,773 and 11,293, while the 15R put up more modest results of 2,857 and 9,512. 

From that perspective, you're losing a fair amount of performance, but real-world use tells a different story. Outside of the handful of games such as Call of Duty: Mobile and PUBG that support the OP15 and 15R's 165Hz displays, the Snapdragon 8 Gen 5 offers more than enough muscle for the majority of applications. Even for most games (like the ones I like to play, including Diablo Immortal and League of Legends: Wild Rift), the Snapdragon 8 Gen 5 is a great match. 

OnePlus also hasn't skimped on the 15R's other internal components. You're still getting 12GB of LPDDR5X Ultra RAM and 256GB of UFS 4.1 storage. That's the same configuration as the base model of the OP15. This translates to a phone that doesn't miss a beat when switching between apps and loading files like images and videos.  

The 15R has a slightly bigger battery, coming in at 7,400mAh, up from 7,300mAh on the OP15. In practice, the two phones offer the same amount of battery life. Putting them through both Engadget's video rundown test, they both ran for 38 hours before their batteries died (which makes sense given the OP15R has a bigger screen). Like the OP15, the 15R comes with the OnePlus 55W SUPERVOOC charger in the box. The adapter can get the 15R from dead to 100 percent in less than an hour. If you hate charging your phone, the 15R makes that process as painless as possible, with a battery that both lasts long and won't be at the outlet for hours.            

Cameras

By this point you're probably wondering what OnePlus cut from the OP15 to make the 15R more affordable. The answer — quite literally — is an entire camera. The new phone is missing a telephoto camera, something you could find on its predecessor, the OnePlus 13R. And as far as I can tell, the two remaining cameras use the same 50-megapixel and 8MP sensors OnePlus shipped on last year's model. The company also hasn't upgraded the glass on either camera. That leaves the selfie camera as the only area to see some change in the form of a sharper 32MP sensor and the addition of autofocus.       

Unfortunately, none of the 15R's cameras stand out. As a whole, they suffer from the same set of problems that plague the OnePlus 15's cameras. They're fine out on a sunny day, but as soon as the light becomes a bit challenging, the 15R struggles with shadow details, resulting in muddy pictures. The more I've used both the OP15 and 15R, the more I've come to the conclusion that OnePlus needs to go back to the drawing board with its new Detail Max Engine. It feels like it's holding back what should, at least on paper, be solid hardware.

There's not much to say here other than the 15R ships with OxygenOS 16, just like the OP15. OnePlus has also promised to support the 15R for the same amount of time as the OP15: four years with software updates and six years with security patches. That's a shorter window than Google and Samsung, both of which promise seven years on all their latest phones. It's hopefully something that OnePlus decides to change starting with the OnePlus 16. The reason I bring that up is that the company’s version of Android is one I like a lot. OxygenOS is slick, with animations that highlight the speed of the 15R's processor and display. The fact the phone comes with the latest version of OxygenOS means you also get access to all of the company's newest AI features, including its Mind Space hub where you can save screenshots and notes for an on-device model to transcribe and summarize.    

 Wrap-up

In short, the OnePlus 15R is the phone for people who don't care about photos and videos. That's the same conclusion I came to with the OP15. If you're a OnePlus fan, the 15R excels in all the areas you would expect the company's devices to make a good showing: performance, battery life and display responsiveness. Given I wasn't too impressed with the OP15's camera, I would actually recommend the 15R over that model. For $200 off the starting price of the OP15, you're getting a device that has almost all of the same strengths of its more expensive sibling.  

Compared to other phones in its price range, such as the Pixel 10 and Galaxy S25 FE, the 15R is not as well-rounded, and can't compete with those devices in camera quality, but you're getting much better performance, battery life and a display they can't match.
