OnePlus has delivered in 2025 with other products such as the OnePlus 14 and 14 Pro and therefore, expectations were high in its latest flagship, the OnePlus 15. It is an impressive product right at the start, with its combination of state-of-the-art performance and high-end design and functionality. 

The OnePlus 15 does not only target pure speed but also offers an excellent display, multi-purpose cameras and a huge battery capable of serving a full day of intensive use. Such high-end features as the Snapdragon 8 Elite Gen 5 and 165Hz LTPO AMOLED display are not a question of whether it is powerful or not, but whether it can actually distinguish itself in the congested flagship market.

An In-Depth Review on OnePlus 15

OnePlus has introduced the OnePlus 15 which is a flagship that offers a balance between the extreme performance and the sophisticated design and features. It has a huge 7,300 mAh, 120W wired and 50W wireless charging, a versatile triple 50 MP rear camera system and a 6.78-inch 165Hz LTPO AMOLED display. The phone provides the highest Snapdragon 8 Elite Gen 5 performance, as well as, IP68/IP69K water and dust resistance. The OnePlus 15 price in Bangladesh, real-life performance, and the quality of the building are also discussed in the review to enable the user make a well-informed choice.

Box Content

This is what you get inside the OnePlus 15 box:

• OnePlus 15 Smartphone
• 120W Charger
• USB Type-C cable
• Protective Case
• SIM ejector tool
• User manual

OnePlus 15 is packed in a well-designed box with all the necessary items to start using it. The phone itself, a 120W fast charging adapter, a USB-C to USB-C cable, a pre-installed screen protector, and a protective case are also included inside. The box also consists of a SIM ejector tool, documentation, and warranty. OnePlus has made the packaging to be functional, whereby the user is provided with all the necessary accessories immediately upon purchase and thus there is no need to purchase additional parts to begin using the device safely and effectively.

Design & Build Quality

Similar to the OnePlus 14 and 14 Pro of last year, the OnePlus 15 does not revolutionize the design, but it perfects what the previous models were attractive. OnePlus has a pair of colour choices, which have their personality. The black variant that I tested is smooth and subtle, whereas the Pearl White one provides a more vibrant and high-quality touch. Both are very classy, but a brighter colour would have brought a more glamorous appearance to those who want something to stand out.

The phone has a glass back and front and is made out of aluminum, which makes it have a solid and high-end feel in the hands. It has a weight of 215 grams, a bit heavier than the competition but the weight adds to the feeling of longevity. The rounded edges allow one-hand usage, despite the huge 6.78-inch screen.

The water and dust protection (IP68/IP69K) also increases its durability because now the user does not have to fear spills or even the rain. Although the phone is a bit taller than compact-device upgraders, its ergonomic design allows one to scroll, read, and play games comfortably. On the whole, the OnePlus 15 is a product that balances the three principles of elegance, durability, and daily usability, continuing the well-developed design aesthetic of OnePlus flagships that the company offers its customers.

Display

The OnePlus 15 has a beautiful 6.78-inch LTPO AMOLED screen with a 165Hz refresh rate, providing an extremely smooth and fluid experience, and in particular, gaming. The refresh rate is dynamically adjusted in everyday use, and therefore you may not always realize when it reaches its maximum, but when using a high-frame-rate game or scrolling through animations, the difference is unbelievable. The panel also accommodates HDR10 + and Dolby Vision which brings depth and vibrancy to the video content.

In the testing, the display reached a peak brightness of approximately 1,800 nits when in high-brightness mode, which allowed it to be read with ease in broad daylight. The colours are vivid and balanced, and blacks are dark and have a great contrast with AMOLED technology. The experience of watching movies or streaming content on OTT platforms is immersive and the experience of reading e-books or browsing is comfortable over long periods of time.

There are also dual stereo speakers in the OnePlus 15 that are used to accompany the display with clear and loud sounds. When you are playing games, watching videos, or just browsing social media, the screen will provide you with a clear picture and bright colours. On the whole, it is a fast, bright, and clear panel, which is among the highlights of OnePlus 15.

Camera

OnePlus is using a versatile and high-end strategy with the camera configuration of the OnePlus 15. The hardware has three 50mp rear cameras, one of them a wide sensor, another one an ultra-wide lens, and a periscope telephoto with 3.5x optical zoom. The 32 megapixel selfie camera has a front facing and can capture 4K videos at 60fps, which is suitable in terms of capturing high-quality selfies and video calls.

Daylight Photo:

Practically, the OnePlus 15 provides an impressive performance under all types of lighting. The shots during the day are crisp and the natural colours and high dynamic range. Photos have a vibrant, lively feel that is not overly saturated with greens and blues. The ultra-wide lens is colour matched to the main sensor, and creates wide shots, which still have a reasonable amount of detail throughout the frame. The periscope telephoto lens is best used in shooting subjects that are far as it gives a clear zoomed-in image without any perceivable softness.

Low-light Photo:

The performance in low-light conditions is good, owing to the optical image stabilization and the Nightscape algorithms. Noise is also kept down to a minimum, although very dark surroundings can cause some fine details to be a little blurred. The portrait mode gives natural skin color and background blur, but very thin edges can sometimes be missed in the difficult shots.

One of the features of the OnePlus 15 is video recording. The rear cameras are up to 8K at 30fps, 4K at 60fps, and have the following features: gyro-EIS stabilization, HDR support, and Dolby Vision recording. The video quality is usually stable and the colours are correct and stabilization assists in diminishing the shaking when using hands to record. The background capture is also good and selfie videos are bright and detailed.

Altogether, the camera system on the OnePlus 15 is a compromise of functionality and quality. It does better in daylight, copes with low-light scenarios effectively and has powerful video features, which makes it a good option when one is an avid photographer and does not need to compromise on a flagship-level of performance.

Performance & Software

The OnePlus 15 still relies on performance, and it does not fail. The phone is equipped with the Snapdragon 8 Elite Gen 5 SoC engine that provides the speed and efficiency of flagships. Combined with 12GB LPDDR5X RAM and UFS 4.1 storage, it provides an experience of smooth multitasking, fast applications opening, and switching between heavy applications. The system files and pre-installed applications do not mean that the user is left without much storage capacity where they can store games, media and productivity files.

When it comes to gaming, OnePlus 15 can easily cope with such demanding games as Genshin Impact, Call of Duty Mobile, and Asphalt 9. Frame rates are not reduced when playing longer and when playing longer the Adreno 840 graphics is able to maintain similar performance without throttling. The 165 ⁻ Hz LTPO AMOLED display and optimized software make animations, scrolling and daily usage of apps incredibly smooth.

The phone is based on Android 16 and OxygenOS 16, which has a simple, clean interface and little bloatware. Although there are the performance mode and display settings that can be adjusted by the advanced users, the novices will find it simple and easy to use. Productivity is increased with the help of AI-driven tools, including fast note-taking, intelligent reminders, and built-in search, but they are less dramatic and disruptive than competitors.

In general, the OnePlus 15 is a version that puts both footloose power and a refined software experience. It is also equally suitable in intense gaming, multimedia or daily chores, so it is one of the most competent and versatile smart phones in the market.

AnTuTu Benchmark & GeekBench Score

The OnePlus 15 really fits in synthetic performance tests. It has a score of about32,96,866 points on the benchmark databases in AnTuTu v10 (CPU: 968,900; GPU: 1.23 million; memory: 489,800 and UX: 740,700). 
The device has a one-core score of approximately 3,700-1,709 and a multi-core score of approximately 11,000-11,236, depending on the test, on GeekBench 6.

These figures indicate the strength of the Snapdragon 8 Elite Gen 5 in the hood, as it demonstrates that the OnePlus 15 is competing in the very high end of the flagship performance category. Meanwhile, sustained load (such as in long loops of AnTuTu) does cause the phone to heat up to a degree and lose some battery, which is something to consider with the intense gaming or benchmarking. 

Battery & Charger

Oneplus 15 has a huge 7,300mAh battery that is aimed at providing all-day power without being bulky. The phone is fairly compact in its size, even though its interior design is efficient, and it can operate both 120W wired and 50W wireless fast charging, the latter of which is provided as the boxed accessory.

In the real world, the OnePlus 15 could comfortably last all day when used under the heaviest conditions, such as playing games, streaming, social media, and shooting with the camera now and then. The battery may safely last almost 1.5 days in moderate usage e.g. a combination of browsing, calls, and limited multimedia, which is why it is one of the longest-lasting flagship devices on the market at present.

Speeds of charging are also impressive. The phone charged to 100% in an approximate of 25-30 minutes using the 120W charger included in it and this means that the phone can be charged up within a short period between tasks. Wireless charging is also quick and convenient, which is flexible to people who want to be cable-free in charging.

Altogether, the battery life and charging options of the OnePlus 15 are outstanding, as it provides both long-lasting performance and one of the quickest charging options on the market, which guarantees a minimum of downtime and maximum productivity all day.
