Early buyer reactions and the most discussed problems so far

The OnePlus 15 arrived with huge expectations, and while many buyers praise its speed and design, day-one complaints have already started surfacing across early adopters and communities. UK users in particular are sharing similar patterns of issues, giving a clearer picture of where the phone may need refinement through software updates.

One of the most discussed complaints is overheating under heavy load. Users who tested long gaming sessions, high-resolution video recording, and benchmarking have reported noticeable heat buildup near the camera area and frame. Although performance remains strong, the temperature increase has surprised many who expected stronger thermal management from a flagship.

The second area of concern relates to the camera. On paper, the triple 50MP system is powerful, but early feedback points to inconsistency rather than failure. Buyers have mentioned that daylight photos are excellent, but high-zoom performance and very low-light scenes can produce softer results than anticipated. Some owners believe that future firmware optimisations will be needed before the camera reaches full potential.

Software behaviour has also become a talking point. A number of users mention occasional micro-stuttering during animations and app switching despite the strong processor. Others say that the removal of the classic alert slider and the introduction of the new programmable key feel more like a change in layout than a functional improvement. The resolution drop from 2K to 1.5K has also disappointed a section of loyal users.

Battery life has generated mixed first impressions. Many users are satisfied with all-day backup, but there are scattered reports of fast draining during early setup, camera use, and 5G streaming. Some believe the phone may need a few charging cycles or an update before battery consumption stabilises, which is common in first-day usage of new flagships.

Design opinions show a clear split. A majority compliment the slim bezels and large edge-to-edge display, calling it one of the most premium front designs OnePlus has made. However, the flat frame receives mixed reviews: some find it modern and bold, but others say it feels sharp in hand compared to curved-edge competitors. A few customers also note that the rear glass finish on specific colour options feels slippery without a case.

A smaller but recurring complaint is related to connectivity. A limited number of users report fluctuating Wi-Fi performance when switching between access points and occasional Bluetooth drops with wireless earphones. These issues are not universal but have appeared often enough to be noticeable among early adopter feedback.

Day-one gaming feedback is also divided. While the phone runs popular titles at high settings, some players mention occasional frame dips during extended matches. Most point again to the heating concern, suggesting that temperature buildup may be influencing performance throttling in specific gameplay scenarios.

Another common request from buyers has been a longer software support lifespan. The phone offers multiple years of Android upgrades and security patches, but some users believe that a premium flagship in 2025 should match the longest support policies in the market rather than fall slightly short.

Despite these complaints, most early owners agree that the OnePlus 15 remains a powerful and premium device. The majority of issues relate to tuning rather than hardware failure, and many users expect future software updates to improve temperature control, camera consistency, and minor system bugs. The strong display quality, battery efficiency for everyday usage, and overall performance keep buyer satisfaction relatively high.

In summary, day-one feedback shows that overheating, camera tuning, software movement, and ergonomics are the most discussed complaints so far. None of these appear to be deal-breakers for most UK buyers, but they highlight the areas where OnePlus may need to make improvements in the coming months to deliver a fully polished flagship experience.
