The OnePlus 15 arrives just ten months after the OnePlus 13, and after using it as my daily driver for a month, I can confidently say the battery life alone makes it worth considering. Spoiler alert: three-day battery life is genuinely transformative.
Design & Build Quality
The OnePlus 15 represents a clear design departure from the OnePlus 13. The circular camera bump is gone, replaced by a square module that’s clearly inspired by Google’s Pixel 9 and 10 series. Despite the similarity, it retains its own OnePlus identity.
I received the Sand Storm finish, which features aerospace-grade Micro-Arc Oxidation treatment — a ceramic-like coating over the aluminum frame that OnePlus claims is extremely scratch-resistant. After a month of use, the frame remains pristine.
Here’s the catch: without a case, this phone is extremely slippery. Only the flat, angular edges provide enough grip to maintain control. If you plan to go caseless, be prepared for some careful handling.



The phone is almost identical in size to the OnePlus 13, and the bezels are impressively thin at just 1.15mm all around. The comprehensive protection with IP66, IP68, IP69, and IP69K ratings means this phone can handle just about anything.
One change I particularly appreciate is the completely flat 6.78-inch AMOLED display. I prefer this over the OnePlus 13’s slightly curved screen — it makes screen protectors easier to apply and eliminates accidental edge touches.
Performance
Performance is great. The Snapdragon 8 Elite Gen 5 processor paired with 16GB RAM and 512GB storage in my review unit delivers buttery smooth performance. Apps launch instantly, multitasking is seamless, and I haven’t experienced any stutters or lag.
I haven’t done any gaming on the phone, so I can’t speak to thermal performance under sustained heavy loads. However, during normal usage — browsing, social media, navigation, podcast listening, and camera use — I’ve experienced no overheating issues. The phone stays comfortably cool.
The display supports up to 165Hz for gaming and is protected by Corning Gorilla Glass Victus 2.
Battery Life: The Star of the Show
This is where the OnePlus 15 truly shines. The massive 7,300mAh battery is exceptional. After a typical day, I have around 70% battery remaining. More impressively, I can use the phone for three full days on a single charge.
The claimed 60-hour battery life is absolutely realistic. For context, my usage includes emails, social media, podcast listening during runs, photography, and web browsing. The battery barely drains.
OnePlus claims the silicon-carbon battery will retain at least 80% capacity after four years — meaning 5,840mAh even after four years of use.
Charging is impressively fast with my 100W USB Power Delivery charger (OnePlus includes a 120W SuperVOOC charger in most markets).
The Qi2 Question
OnePlus chose not to include Qi2 with built-in magnets, citing weight concerns. I think this is a missed opportunity — Qi2 is genuinely useful. However, OnePlus offers cases with built-in magnets that enable 50W AirVOOC wireless charging. Without the magnetic case, you’re limited to standard Qi speeds.
Camera System
OnePlus ended its Hasselblad partnership and introduced the DetailMax Engine. All three 50MP sensors are physically smaller than the OnePlus 13’s cameras. Despite the downgrades on paper, I find the cameras comparable to the OnePlus 13 in real-world use. Both phones produce great results for my needs.



The camera app is fast and responsive. Double-press the power button to launch instantly. Night mode delivers impressive results, and the 3.5x telephoto provides a natural focal length for portraits.
The Plus Key (Action Button)
The beloved Alert Slider is gone, replaced by the Plus Key — similar to Apple’s Action Button. I do miss the slider, mostly for nostalgic reasons (I rarely used it since I keep my phone on silent).
The Plus Key is more versatile. I have mine set to save screenshots to Mind Space, but you can configure it for camera, flashlight, translation, or sound settings. Functionally, it’s better because it can do more.
Software & Features
Running OxygenOS 16, the phone stays close to stock Android while adding thoughtful enhancements. The standout feature is Mind Space, accessible via the Plus Key. It can record and transcribe audio, capture and interpret screenshots, and organize notes. I find it really useful for notes on the go.
The familiar split-screen apps, floating windows, and Open Canvas features all work flawlessly. Everything feels stable with no bugs in my month of testing.
OnePlus commits to four years of OS updates and six years of security patches — respectable, though behind Samsung and Google’s seven years.
Value & Verdict
At 11,990 SEK for 12GB/256GB and 12,490 SEK for 16GB/512GB, the OnePlus 15 is positioned as a premium flagship. The OnePlus 13 now costs 9,395 SEK (256GB) and 9,600 SEK (512GB).
After a month with the OnePlus 15, I feel it is really great. The three-day battery life is transformative — you stop worrying about battery entirely. The flat display, improved durability, and premium build quality all contribute to an excellent experience.
What I love most: The incredible three-day battery life, flat display, premium build quality, and fast performance.
Room for improvement: Very slippery without a case, Qi2 should be built-in, and software support should match the seven-year commitment from competitors.
Who Should Buy It?
If you’re in the market for a flagship phone with a monster battery and a great camera, the OnePlus 15 is a really great option. It delivers excellent performance, outstanding battery life, solid cameras, and premium design.
However, if you don’t mind missing out on the extra battery and new design, the OnePlus 13 is still a solid option at a better price.
Final Verdict: Highly Recommended
The OnePlus 15 continues OnePlus’s tradition of delivering flagship performance at competitive prices. If battery life is a priority — and it should be — the three-day endurance is genuinely game-changing. Combined with fast charging, excellent performance, and refined design, it earns its place among the best Android flagships of 2025.
