The verdict

Across 19 reviews from 16 outlets, the OnePlus 15 comes out as a strong flagship, with battery life, charging speed and raw performance praised most consistently. Camera, software and sustained-load heat divide reviewers, and published scores run from Android Authority’s 6/10 to full marks at TechRadar and T3. Confidence in this consensus is medium.

Best for: Anyone who puts battery life, fast charging and a bright, smooth screen ahead of having the best camera.
Skip it if: You want a class-leading camera, the longest software support, or a phone that stays cool through long gaming sessions.

In detail

Camera: 7.4/10

Reviewers agree the main camera and 4K 120fps video are strengths, while telephoto and ultrawide low-light shots and zoom processing are weaker. Trusted Reviews found detailed images in bright and low light, and NotebookCheck praised a detailed, color-accurate main camera. Android Central called the results surprisingly good despite hardware downgrades. Android Authority and 9to5Google judged the cameras worse than the OnePlus 13’s, and Engadget said photos trail Apple, Google and Samsung flagships, with weak shadows and low light. 91mobiles found its stills came out at 12MP rather than the claimed 26MP. Outlets are split, so expect a good camera rather than a class-leading one.

Battery life: 9.8/10

Outlets agree battery life is excellent. TechRadar recorded 26 hours 25 minutes in its rundown test, the longest it has tested, and the phone was still running after three days. Android Central measured 25 hours 13 minutes, ahead of the Galaxy S25 Ultra’s 17 hours 14 minutes, and Engadget’s video rundown lasted 38 hours 30 minutes, eight hours longer than the OnePlus 13. Android Police said it lasts through a second day and often a third, and Smartprix Bytes ended heavy days with 35-40% left. Android Authority and Trusted Reviews gave only mild verdicts without measurements.

Performance: 8.5/10

Everyone agrees raw speed is top-tier, with multi-core Geekbench results of roughly 10,600 to 11,200. Android Central’s result beat the iPhone 17 Pro Max, and TechRadar said gaming exceeded every other phone it has tested. Sustained load divides reviewers. Android Authority’s GPU stress test stopped after 15 of 20 runs because of heat, NotebookCheck reported significant throttling and possible shutdowns, and MySmartPrice Gear and Beebom also reported heat and throttling. Android Police, TechPP and Smartprix Bytes found it cool and steady in heavy gaming. If you play demanding games for long stretches, weigh the heat reports.

Display: 9.1/10

Outlets agree the screen is bright, smooth and vivid, with 165Hz limited to select games. Digit measured a 3120 nit peak with accurate color, and Android Central called it best-in-class and found no low-frequency PWM. NotebookCheck warned that PWM flicker may bother sensitive users. The drop to a lower resolution than the OnePlus 13 split opinion: Android Authority called it a step backward, while 9to5Google and Smartprix Bytes said it was not noticeable. TechRadar noted the Pixel 10 Pro is brighter, and 91mobiles said the lack of an anti-reflective coating makes angled sunlight viewing harder.

Software: 7.9/10

OxygenOS 16 divides reviewers. TechRadar called it polished and elegant, MySmartPrice Gear found it clean with practical AI features, and T3 praised its smoothness and customization while noting some features lack joined-up thinking. Android Central reported annoying bugs that made the phone feel unfinished at launch, and 9to5Google called the interface an iOS imitation with buried, uninspired AI. Engadget and T3 noted that the pledge of four OS upgrades and six years of security patches is worse than Google and Samsung offer. Smartprix Bytes liked the battery controls.

Charging: 9.4/10

Charging is consistently fast. Trusted Reviews measured a full charge in 45 minutes and 50% in 19 minutes on the 120W charger, and Android Police also found just under 45 minutes. Gizbot measured 30-35 minutes and Engadget about 40. Android Central found it added far more charge in 30 minutes than the Galaxy S25 Ultra, and Smartprix Bytes said the 50W wireless and reverse charging beat Samsung and Google. Engadget noted that wireless charging needs a proprietary puck, and Gizbot said it needs a magnetic case because the phone has no built-in magnet. Several outlets only listed the specs.

Design & build: 8.6/10

Reviewers agree on durability. TechRadar, Trusted Reviews and Smartprix Bytes praised the tough frame and IP69K-level protection, and T3, TechPP and Smartprix Bytes noted the 8.1mm body despite the big battery. Looks divide them. T3 and 91mobiles liked the finish and flat grip, while 9to5Google, Engadget, Beebom and Android Central called the design generic or iPhone-like. Android Authority and Android Central regretted the lost alert slider. Android Police said the matte back picks up scuffs easily, and NotebookCheck heard a faint creak when twisting the chassis.

Value: 8.7/10

This category rests on fewer outlets. TechRadar called it the best phone at full price, and Trusted Reviews said £849 in the UK is significantly cheaper than rival flagships. T3 also saw it as keenly priced against the Galaxy S25 Ultra and Pixel 10 Pro XL. Android Police compared the $900 US price favorably with the S25 Ultra but expected limited US carrier support to keep it niche, and reported FCC delays that held back the US launch. 9to5Google later noted FCC approval. Gizbot said the base price in India rose to ₹72,999, and 9to5Google noted ₹5,000 price hikes in India.
