OnePlus 15 Review
If you plan to buy a flagship phone in 2025, then this OnePlus 15 review will help you determine whether it’s really ahead of the rest. OnePlus has refined the design, increased the efficiency, and thrown in a huge battery but also made choices that are likely to polarize fans. This summarized 9-point review details aspects of the design, display, playability, camera, battery, software and overall value of the OnePlus 15/
Cleaner design but the Alert Slider is gone
The OnePlus 15 features a premium matte finish, flat frames, and a new square camera module. It’s both fresh yet familiar. The violet color looks classy without being too loud. However, fans might be a little disappointed to see the removal of the popular Alert Slider and its replacement by a Plus Key, which doesn’t feel as convenient. Still, the overall design carries modernity with polish.
Slim body, huge 7,300mAh battery
One of the biggest highlights in this OnePlus 15 review is the big 7,300mAh battery inside this slim 8.1mm body. Surprisingly, the weight is so well-balanced that it could be lighter than one would expect from the device. The only drawback: this slim frame combined with a powerful chipset means heating can, and will, happen during demanding tasks.
Snapdragon 8 Elite Gen 5: Record-breaking performance
The Snapdragon 8 Elite Gen 5 chipset places the OnePlus 15 among the very best flagship performers. Testing in Geekbench scored 9,629, while AnTuTu hit a high of 3.6 million — the highest we’ve seen in our testing of the OnePlus 15. It handles heavy apps and top-tier gaming without a stutter. Sustained performance isn’t perfect, but peak power is incredibly good.
Gaming is smooth, though the phone tends to warm up under stress
OxygenOS 16 makes everything feel super clean and responsive. Games like Genshin Impact and BGMI run smoothly, although hitting 60fps involves tinkering with graphics settings. Temperature crosses 50°C in long sessions, and battery drain increases accordingly. As with our review of the OnePlus 15, we found that long gaming will indeed affect sustained performance, but gaming for everyday use is still excellent.
1.5K AMOLED display: bright and smooth
The 6.7-inch AMOLED screen is sharp with great colours and a 165Hz refresh rate. In real usage, though, the phone mostly runs at 120Hz. The shift from QHD+ to 1.5K resolution feels like a downgrade on paper, even though real-world differences are minimal. HDR peak brightness has also dropped a bit. The display holds up well enough for movies, games, and general usage.
Battery life is one of the best in 2025
One of the major highlights in this review of the OnePlus 15 is its battery performance. It lasts for over 15 hours with use in Balanced mode without any problem. Heavy gaming or streaming brings down the backup, but 120W charging fills up the battery in about 25 minutes. This makes the OnePlus 15 one of the strongest battery performers this year.
Cameras are reliable but not flagship-leading
Its main camera clicks detailed, natural-looking photos with decent colours. Low-light results are decent, but not the best in this segment. The telephoto lens is where the phone doesn’t quite cut it because zoom shots aren’t as sharp as on some rivals. Summing it up, the camera system is good but it isn’t groundbreaking; hence, it’s an important thing to note in this OnePlus 15 review.
OxygenOS 16 is smooth but familiar
It also keeps the UI clean and minimal, free from heavy bloatware. Still, veteran users of OnePlus may find it is feeling more like iOS than classic OxygenOS. The subtraction of the Alert Slider has impacted the signature OnePlus experience in yet another way. Otherwise, the software is still fast, stable, and polished.
Stable flagship with emphasis on reliability, not risks
The final verdict of this review of the OnePlus 15 is straightforward: OnePlus played it safe. Strong performance, excellent battery life, quick charging, a high-end design, and seamless software are all features of the OnePlus 15. However, there are limitations, like noticeable thermals during stress, a 1.5K display instead of QHD+, and average telephoto performance.
The OnePlus 13 was a powerhouse built for gamers and tech lovers. Playing Call of Duty Mobile on this device feels ultra-smooth with zero lag, thanks to its advanced processor and sharp display. The new Ultra Violet color option looks stunning and gives the phone a bold identity. Even in tough environments like a sand storm, its durable build keeps performance strong.
Final words for OnePlus 15 review
The OnePlus 15 will undoubtedly be a capable and rapid flagship for average users. However, if you are an enthusiast expecting leaps in development, this OnePlus device was perhaps too conservative. Overall, however, the OnePlus 15’s review suggests this should be a well-rounded phone with exemplary day-to-day performance.
