There’s a strange sense of calm that comes with a big phone upgrade. One minute you’re squeezing the last breath out of an ageing device, the next you’re smugly swiping through a shiny new flagship that does everything faster, smoother, and louder. That was me with the OnePlus 15, jumping from the 11 and bagging a deal so good it made me question whether I’d clicked the wrong model.
Thanks to a flurry of discounts, trade-in offers, and a cheeky blue light code (cheers to the other half), I walked away with the phone, a OnePlus Watch 3, and a case for just over £500. And no, that’s not a typo, I saved over £690 in total. So, financially speaking? Off to a flying start. But deals aside, how does the OnePlus 15 actually perform day-to-day?
Before we jump into the review, though, let’s check out our quick unboxing:
Slick, snappy, and built to last
First off, it’s fast. Stupidly fast. Powered by the Snapdragon 8 Gen 5, it loads everything with that blink-and-you-miss-it vibe. The 165Hz refresh rate? Silky smooth. Apps open in a flash. Multitasking is effortless. And it stays cool under pressure, even when I’m juggling emails, socials, football scores, and fantasy league heartbreaks all at once.
The 7300mAh battery is an absolute unit. I’m usually glued to my phone, but even with heavy daily use, it comfortably lasts two full days. Combine that with 120W fast charging and the optional 50W wireless AirVOOC, and it’s one of the best battery experiences I’ve had in years. Even just a short drive with it sat on the wireless charger in my car is enough to keep it topped up.
Gaming on the OnePlus 15: Serious firepower
Let’s not forget we’re a gaming site. And yes, the OnePlus 15 pulls its weight in that department. Out of the box, it’s ready to go with Game Assistant, OnePlus’s own built-in gaming toolkit. Fire it up during a session, and you’ll get a neat overlay with tools to block notifications, monitor performance, and tweak settings on the fly.
You can choose between Performance, Balanced, or Battery Saver modes depending on whether you want to max out frame rates, keep things cool, or stretch your battery. It’s a small thing, but it gives the OnePlus 15 a sense of gamer-focused polish. There’s also a “mistouch prevention” feature for edge detection, screen recording tools, and a voice modulator if you want to mess with your mates in voice chat.
Games like Call of Duty: Mobile, PUBG, and Diablo Immortal ran buttery smooth, consistently delivering 120FPS gameplay in supported titles, with no real sign of thermal throttling or slowdown. Just bear in mind, you won’t get console-level sound. The speakers are crisp enough for casual gaming, but if you want that proper bassy boom, grab a headset or some decent earbuds.
Camera controversy: Upgrade or compromise?
Now, let’s talk camera. Some reviewers reckon the OnePlus 15 is a step back from the 13, maybe. But skipping a few generations meant this was a noticeable upgrade for me. It takes crisp, vibrant shots, and the new AI features for enhancing photos can work wonders… unless you’re snapping something with fine text. That’s when the AI sometimes throws a strop, replacing letters with weird blocks or squashing detail into mush.
That said, the triple 50MP camera system is more than capable for everyday use. You get a wide-angle shooter with shake-free OIS, a periscope telephoto for zooming without turning images into pixel soup, and a 112° ultra-wide that’s perfect for those dramatic outdoor shots. It’s not quite pixel-perfect, but it’s solid – and easily handled all my daily snaps, from pets to tech unboxings.
OxygenOS, audio and everyday annoyances
Post-launch, I had a few signal issues, which I initially pinned on my service provider. But since the latest OxygenOS update, things have smoothed out massively. The new outdoor signal booster widget is genuinely handy, letting you toggle enhanced reception with a tap, especially when you’re somewhere that makes you question whether Wi-Fi ever existed.
Audio is decent overall. The treble is sharp, vocals stand out, and podcasts or spoken-word videos sound clean and clear. But bass? It feels like a slight step back from the OnePlus 11. Not a deal-breaker, but noticeable if you’re listening to heavier tracks or want punch in your music.
Final thoughts on the OnePlus 15
The OnePlus 15 might not be the most hyped phone of the year, but it’s one of the smartest upgrades I’ve made. With its rock-solid performance, brilliant battery life, gaming tools, and premium design, it feels every bit a flagship device, especially at the price I paid.
Sure, it’s not perfect. The AI-enhanced camera needs refinement when it comes to reading text, the audio lacks a little warmth, and the occasional UI hiccup reminds you you’re not holding a Pixel or iPhone. But that doesn’t matter. For most people, especially those into gaming, productivity and all-around solid performance, the OnePlus 15 is absolutely worth a look.
