OnePlus 13 vs Xiaomi 15: In July 2025, both OnePlus 13 and Xiaomi 15 are present in the market with their great features and strong performance. Both have the same latest Qualcomm Snapdragon 8 Elite processor, which is great for gaming and multitasking. The camera setup is also almost the same in both—three 50MP sensors that can please photography enthusiasts from every angle. But still there are many big differences between these two phones—from design to display, battery to charging and price. So if you are also confused whether to buy OnePlus or Xiaomi, then let’s understand everything one by one in easy language.
Design & Style:
The look of OnePlus 13 is more premium this time than before. Its size is slightly bigger and the weight is also slightly more, about 210 grams. Its new “quad-curved” screen design gives it a different feel when held in hand, and it also has an in-display ultrasonic fingerprint sensor. On the other hand, Xiaomi 15 is light and compact, weighing just 191 grams. Its body is thin and there are very thin bezels around the screen, which makes this phone look very stylish and handy. If you like to use the phone with one hand, then Xiaomi 15 will be easy to use.
Display & Visuals:
OnePlus 13 has a large 6.82-inch QHD + LTPO AMOLED screen, which gives brightness up to 4500 nits. That is, whether it is outside in the sun or in low light at night, you will see everything clearly. Apart from this, its picture quality and color reproduction are also great. On the other hand, Xiaomi 15 has a 6.36-inch LTPO OLED screen, which gives 1.5K resolution and its brightness goes up to 3200 nits. The screen is small but looks clear and bright. If you like a bigger screen and more details, then OnePlus 13 will look better, but if you are a fan of a compact phone, then Xiaomi 15 is also very good.
Performance & Processor:
In terms of performance, both the phones are second to none. Both have Qualcomm Snapdragon 8 Elite chipset, which is the fastest and most powerful processor of the moment. Gaming, video editing, multitasking—every task runs smoothly on these phones. Also, OxygenOS 15 (OnePlus) and HyperOS 2 (Xiaomi) based on Android 15 also make the user experience of both quite fresh and customizable.
Camera Setup:
Both the phones have something special for camera lovers as well. The color tuning in OnePlus 13 looks very natural and professional due to the partnership with Hasselblad. It has triple 50MP cameras, with a periscope telephoto lens that gives 3x optical zoom. On the other hand, Xiaomi 15 has been given tuning by Leica, which gives a different feel and deep color tone in the photos. Its telephoto lens supports 2.6x optical zoom. Overall, if you want zoom and color tuning in detail, then OnePlus is slightly ahead, but Xiaomi is also not behind in photography.
Features & Tech:
Talking about connectivity, both the phones support new standards like 5G, Wi-Fi 7 and Bluetooth 5.4. OnePlus 13 has an extra advantage of IP69 certification, which protects this phone from high pressure water jets as well as IP68. Xiaomi 15 only has IP68 certification, which provides a lot of protection from water and dust, but not as much as OnePlus 13.
Battery & Charging:
OnePlus 13 has a big 6000mAh battery, which comes with silicon-carbon technology. Because of this the battery lasts longer. It also has 100W fast charging, 50W wireless charging and a special magnetic wireless charging support. On the other hand, Xiaomi 15 has a 5240mAh battery, which supports 90W fast charging and 50W wireless charging. That is, charging is quite fast in both the phones, but the battery backup of OnePlus 13 can be considered slightly better.
Price & Variants:
Now let’s come to the most important thing – price. The starting price of OnePlus 13 has been kept at around ₹ 69,999 in India, in which you get more RAM and storage options. At the same time, the starting price of Xiaomi 15 is around ₹ 64,998, and its base variant gets a little more storage but a little less RAM. Meaning if you want to save a little budget and want a sleek phone, then Xiaomi 15 is a good option. But if you want more battery, bigger screen and extra features, then OnePlus 13 can be the perfect choice.
Final Verdict:
So now let’s talk about the conclusion. If you are looking for a phone with a big screen, powerful battery, high performance and more resistance, then OnePlus 13 is made for you. On the other hand, if you want a phone that is lightweight, compact and has premium features at a slightly lower price, then Xiaomi 15 is also not far behind.
Everyone has different needs—some want a bigger display, some want less weight of the phone. Both the phones are top class, now the decision is in your hands that what you like more.
