Name: OnePlus 15
Brand: OnePlus

A battery percentage changes how you use a phone. If you usually turn off navigation, save a video for later or hunt for a socket at dinner, the OnePlus 15 makes a stronger case than a phone that only looks faster on a specifications sheet. Its unusually large battery comes with a few decisions about charging, storage and games.

Battery & Charging

7,300mAh typical
Up to 80W SUPERVOOC with the included US charger
Up to 100W with the optional OnePlus SUPERVOOC 100W Dual Ports GaN Power Adapter Lite

Tom’s Guide recorded 25 hours and 13 minutes in its battery drain test and reached 81 percent from empty in half an hour with the included SUPERVOOC charger. ¹ Navigation, camera recording and games will change how long a charge lasts. The practical benefit is the margin it gives you when an errand turns into a full day out. For fast top-ups, pay attention to the charger and cable you pack.

Gaming Performance & Storage

Up to 165Hz in supported games
12GB/256GB or 16GB/512GB

A panel that can refresh 165 times a second helps when the game supports the mode and can deliver those frames. It won’t speed up a video or turn a capped game into a high-frame-rate one. If you install several large games, the extra storage is an easier reason to pick the larger configuration than a promise of better play in every title. OnePlus pairs each memory amount with a specific capacity.

Cameras

50MP main
50MP ultrawide
50MP 3.5× telephoto

The stabilized 3.5× telephoto gives you a tighter view of a performer on a stage, while the ultrawide makes it easier to fit a group into a small room. All three rear cameras carry a 50MP label, but sensor, lens and light still affect the result. For video, the rear system supports up to 4K at 120 frames per second and the front up to 4K at 60.

Software & Service

OxygenOS 16 at launch
Four Android OS upgrades
Six years of security support

OnePlus ended new product rollouts in North America in 2026. Its notice says software updates and security patches continue for existing devices. Eligible devices can still get repairs, and warranty coverage follows the terms for your device. ³ For a US marketplace purchase, keep the receipt and check that the seller and model qualify for the warranty you expect.

Display

6.78-inch AMOLED
2772 × 1272
1–120Hz adaptive

The 6.78-inch AMOLED has 2772 × 1272 pixels and adapts between 1Hz and 120Hz in ordinary use. The separate 165Hz ceiling applies in supported games. If you mainly read, browse and watch video, the screen area and normal refresh range describe your experience better than the gaming maximum.

Connectivity

Dual nano-SIM slots and eSIM
USB 3.2 Gen 1
Wi-Fi 7

OnePlus equips the US 15 with two nano-SIM slots and eSIM support, useful when choosing a work line or a local travel plan. USB 3.2 Gen 1 gives the phone a faster wired path for offloading recorded video than USB 2.0. It also supports Wi-Fi 7 when paired with a compatible access point.

Alternatives

Keep a phone you like if a small power bank can cover an occasional trip. For someone who needs that power bank most afternoons, the extra battery built into the OnePlus is a benefit they can use every day.

Verdict

The OnePlus 15 earns its place on endurance. I’d buy the 256GB model for someone who streams and offloads photos, and put the extra money toward 512GB only if games or video regularly fill their phone.
