2. A Massive Battery That Keeps Going And Going

Battery life is often the make-or-break factor when choosing a flagship. And here is where the OnePlus 15 truly shines. It packs a 7,300mAh battery, which is significantly larger than what you will find in most premium smartphones today.

For context, many flagship phones- like the Samsung Galaxy S25 Ultra– offer around 5,000mAh. Even the OnePlus 13 had a 6,000mAh battery. So, you are getting a serious upgrade here.

This means you can easily go a full day or more without needing to recharge, even if you are constantly streaming, gaming, or taking photos.

And when you do need to power up, the charging speeds are jaw-dropping. The phone supports 120W wired charging and 50W wireless charging. In practical terms, you can go from 0% to 100% in roughly 25 minutes with the wired charger. No more waiting around for your device to juice up before you head out.

The OnePlus 15 features are all about the perfect balance between endurance and convenience- something most phones still struggle to achieve.

3. OxygenOS 16: Smarter, Cleaner, And More Fun

Software is where OnePlus has always excelled, and OxygenOS 16 continues that tradition. While it is not a radical redesign, it brings several subtle improvements that make the experience smoother, smarter, and more enjoyable.

From the moment you unlock the phone, you will notice playful animations and cleaner transitions that make the interface feel polished. Navigation is easier too, thanks to the new Predictive Back Gesture, which shows you where you will land when swiping back- no more accidental exits from apps.

There is also a new AI section in the settings, where you can control features like AI Search and AI Writer, or adjust how the phone’s “Plus Key” interacts with Plus Mind, OnePlus’s personalized assistant feature.

Customization remains at the heart of OxygenOS. You can play around with dynamic Flux Themes, tweak colors, or personalize icons to make your phone feel uniquely yours.

Overall, OxygenOS 16 feature in the OnePlus 15 feels fast, intuitive, and thoughtfully designed. It is still one of the cleanest Android experiences out there- and now it is even better.

4. Gaming Like You’ve Never Experienced Before

If you are someone who loves gaming on your phone, the OnePlus 15 features take things to a whole new level. Thanks to the Snapdragon 8 Elite Gen 5 chip, it is capable of delivering outstanding performance.

This phone does not just run games- it optimizes them. OnePlus has introduced its own CPU Scheduler, which intelligently prioritizes resources depending on what you are doing. So, when you launch a demanding game, it ensures maximum performance without draining your battery unnecessarily.

Then there is OP Gaming Core, which maintains consistent frame rates and minimizes lag, even during long sessions. Combine that with the new OP FPS Max feature, and you can push frame rates up to a silky-smooth 165Hz in supported games like Call of Duty: Mobile.

To keep things cool, the phone’s advanced Glacier VC cooling system ensures it does not overheat- even during intense gameplay.

During testing, users have reported significantly improved stability and visual quality compared to previous OnePlus devices. If you enjoy competitive gaming or just want a buttery-smooth experience, the OnePlus 15 delivers like few others can.

5. The DetailMax Camera System: Photography Reinvented

Let us now talk about the next OnePlus 15 feature, i.e., the camera. It is one area where OnePlus has made a big shift this year. With the OnePlus 15, the brand introduces its very own DetailMax Engine, moving away from its long-standing partnership with Hasselblad. And honestly, it is an impressive transition.

The triple-camera setup- 50MP wide, 50MP ultra-wide, and 50MP telephoto (3.5x optical zoom)- works well to deliver photos that are crisp, colorful, and full of depth.

Compared to the OnePlus 13, the improvements are immediately noticeable. You get better contrast, wider dynamic range, and superior noise control, especially in low light. Colors look true to life without being overly saturated, and shadows are handled beautifully, giving images a more natural feel.

The 32MP front camera is equally capable, producing sharp selfies even in tricky lighting conditions.

On the video side, the OnePlus 15 supports high-resolution recording with advanced stabilization, making it a great choice for vloggers and content creators alike.

If you love capturing the world around you, the DetailMax system will make photography on the OnePlus 15 an absolute joy.

Bonus: A Fresh New Look

Of course, a flagship phone wouldn’t be complete without a stunning design- and the OnePlus 15 certainly delivers.

This year, OnePlus has moved away from the familiar circular camera bump and opted for a sleeker square module, giving the phone a more modern and balanced appearance.

It is available in Sand Dune, Misty Purple, and Absolute Black, each with a premium matte finish that resists fingerprints and feels smooth in the hand. Despite housing that huge battery, the phone manages to stay relatively slim and light at 161.4 x 76.7 x 8.1mm.

Additionally, with IP68 and IP69K ratings, the OnePlus 15 can handle everything from accidental splashes to high-pressure water jets- perfect if you are prone to the occasional coffee spill or rainy-day photo shoot.
