Phone Comparisons: OnePlus 15 vs OnePlus 13
OnePlus announced its new flagship smartphone, the OnePlus 15, in China, its homeland. It is coming to global markets, but we’ll have to wait a bit before that happens. Therefore, at this point in time, we still haven’t reviewed the phone, but we can compare it to its predecessor. For more information, however, you’ll have to wait for our review, which will come after the global launch. For the time being, we’ll stick to the facts. In this article, we’ll compare the OnePlus 15 vs OnePlus 13.
As per usual, we’ll kick things off with the spec sheets of both phones and work our way from there. We’ll be comparing their designs, displays, performance-related details, battery setups, camera offerings, and the last is the audio section. Let’s get to it, shall we?

OnePlus 15 vs OnePlus 13: Design
The OnePlus 15 does look notably different than its predecessor, that’s hard to deny. Still, there are a lot of similarities between the two phones. From the front, they do look very similar. The corner curvature is a bit more pronounced on the new model. Both smartphones have flat displays, but the OnePlus 15 does not have the quad-curved glass approach of the OnePlus 13. It’s flat flat now. Both devices have a centered display camera hole up top, and thin, uniform bezels around the display. The thing is, those bezels are thinner on the OnePlus 15, they’re only 1.15mm thick.
Both devices have flat frames, but still different. The OnePlus 13 includes chamfered edges, and a smaller flat surface. The OnePlus 15’s frame does curve towards the edges, but only slightly. The power/lock and volume up and down buttons sit on the right-hand side of both smartphones. The OnePlus 13 also has an alert slider on the left. Well, that slider has been replaced by a customizable button on the OnePlus 15, even though it sits in the same spot as the slider.
If we flip them two phones around, you’ll see notably different backplates. The OnePlus 13’s backplate does curve on all sides, the same as the glass on the front. The OnePlus 15’s is flat, and it only curves slightly towards the very edges. The camera islands are also different, OnePlus went from a circular one, to a squarish one. They also look notably different. The OnePlus 15 also doesn’t come in an eco leather variant, unlike the OnePlus 13. All models of the OnePlus 15 have glass on the back.
The new model is slightly shorter, slightly wider, and slightly thinner. The weight of the two phones is basically the same, there’s only a slight difference. Both devices also offer outstanding water and dust resistance ratings, though the OnePlus 15 has the upper hand in that area as well.
OnePlus 15 vs OnePlus 13: Display
The OnePlus 15 features a 6.78-inch LTPO AMOLED display, which is flat. It can project up to 1 billion colors, and its refresh rate goes up to 165Hz, but only during gaming. Dolby Vision is supported, as is HDR10+ content, and HDR Vivid. High-frequency PWM dimming is also a feature here, while the display can get immensely bright when needed. The screen-to-body ratio is at around 91% here, while the resolution is 2772 x 1272. The display aspect ratio is 19.5:9, while we still don’t have any information regarding display protection.

The OnePlus 13, on the other hand, has a 6.82-inch LTPO AMOLED display, which is flat with a curved glass on top of it. This display can also project up to 1 billion colors, and it has an adaptive refresh rate (1-120Hz). It has high-frequency PWM dimming, Dolby Vision, HDR10+, and HDR Vivid support. The peak brightness is immensely high, while the screen-to-body ratio is at around 90%. The resolution here is 3168 x 1440, while the Ceramic Guard glass protects the display.
There’s really not much to complain about here, if anything. Both displays are large, vivid, offer great viewing angles, and have good touch response. Both of them are also very sharp and can get very bright when you need them to. The OnePlus 13’s is a bit sharper, but that’s not something you’ll notice at all. The OnePlus 15’s display allows you to utilize a higher refresh rate in games. You’ll be fine with either of these two panels, in all honesty. Just note that we still didn’t test out the OnePlus 15’s display at this point, more info is coming in our review. On paper, though, it looks great.
OnePlus 15 vs OnePlus 13: Performance
The OnePlus 15 is fueled by the Snapdragon 8 Elite Gen 5 processor, Qualcomm’s latest and greatest chip. That processor is boosted by 12GB or 16GB of LPDDR5X RAM and UFS 4.1 flash storage. The OnePlus 13, on the flip side, utilizes the Snapdragon 8 Elite chip, along with LPDDR5X RAM and UFS 4.0 flash storage. Neither phone supports storage expansion, in case you were wondering.
The OnePlus 13 didn’t really slow down over time. The phone still offers outstanding performance, though, granted, it launched back in January (global version). We’re expecting something similar from the OnePlus 15, too. That phone offers an extremely powerful spec sheet, even more powerful than the OnePlus 15. Not only is the SoC more powerful, but the storage is faster. We’ll have to test it out to be sure.
The OnePlus 13 did great with gaming, as it is not only immensely powerful, but it also has proper cooling. Based on the specs, the OnePlus 15 should be able not only to match that, but do even better than the OnePlus 13. Once again, we’ll have to wait and see, but based on past models, we’re not expecting problems in the gaming department, not at all.
OnePlus 15 vs OnePlus 13: Battery
The OnePlus 15 features a 7,300mAh battery on the inside, while the OnePlus 13 includes a 6,000mAh battery. To put things into perspective, the OnePlus 13 already has a large battery for its size, let alone the OnePlus 15. Both of those battery packs are silicon-carbon batteries, too, by the way. The OnePlus 13 offers great battery life, so we do have high hopes for the OnePlus 15, too.
We still didn’t get around to testing its battery, as the global model is not official yet at this point, but it has a more power-efficient SoC, storage, and a notably larger battery. The OnePlus 15 should be able to beat the OnePlus 13 in the battery life department, easily. Whether that will happen, we’ll see, but that’s what we expect to happen. That’s the only scenario that makes sense based on everything. Either way, you shouldn’t really worry about battery life on either phone, OnePlus made sure it’s all good in that department.
The OnePlus 15 does support slightly faster charging than its predecessor, 120W vs 100W wired charging. If we had to guess, we’d say that they’ll charge in about the same time. Larger battery and faster charging in the OnePlus 15 should even things out. Do note that users in the US will get 80W wired charging, almost certainly, just like they did with the OnePlus 13. Both smartphones also support 50W wireless charging and 5W reverse wired charging.
OnePlus 15 vs OnePlus 13: Cameras
The OnePlus 15 has three 50-megapixel cameras on the back, just like the OnePlus 13. The thing is, all three of those cameras have smaller sensors, not to mention that Hasselblad is not a part of the picture anymore. We still didn’t do our full-fledged camera test on the OnePlus 15, but on paper, things are not looking great. In fact, the OnePlus 13 does seem to have a better camera setup than the OnePlus 15.

The OnePlus 15 features a 50-megapixel main camera (1/1.56-inch sensor size), along with a 50-megapixel ultrawide unit (1/2.88-inch sensor size, 116-degree FoV). The third camera on the back is a 50-megapixel periscope telephoto camera (1/2.76-inch sensor size, 3.5x optical zoom).
The OnePlus 13, on the other hand, uses a 50-megapixel main camera (1/1.43-inch sensor size), a 50-megapixel ultrawide camera (1/2.75-inch sensor size, 120-degree FoV), and a 50-megapixel periscope telephoto camera (1/1.95-inch sensor size, 3x optical zoom). On top of that, Hasselblad is a part of the picture, not to mention that the aperture on the main and periscope telephoto cameras is wider on the OnePlus 13.
We do already have some camera samples of the OnePlus 15 out there, in case you’d like to check those out. As things stand at the moment, the OnePlus 13 could take the win in that department, we’ll see.
Audio
Both of these phones include stereo speakers. The ones on the OnePlus 13 are actually really good. They’re not only plenty loud, but offer good quality output as well. We’re hoping to get something similar out of the OnePlus 15.
Neither phone has an audio jack, but you can connect your headphones via their Type-C ports. The newer phone includes Bluetooth 6.0 for wireless audio connectivity, while the OnePlus 13 supports Bluetooth 5.4.
