OnePlus appears to be preparing a big battery upgrade for its next T-series phone. Leaks suggest the OnePlus 15T will arrive in early Q2 with dramatic boosts to battery capacity and display speed, while keeping much of the formula users liked in the 13T line.
What the leaks say: battery, screen and core specs
According to reliable tipster reports, the OnePlus 15T will jump to a massive 7,000mAh battery — and OnePlus reportedly wants to push that number as high as 7,500mAh in some variants. That’s a notable step up from last year’s 13T/13s models and would give the phone a clear endurance advantage in its class.
- Display: flat 6.3-inch LTPS OLED, 1.5K resolution, 165Hz refresh rate
- Processor: Snapdragon 8 Elite Gen 5 (full Elite version, not the lower-binned Gen 5)
- Battery: ~7,000mAh (possible 7,500mAh target)
- Biometrics: ultrasonic in-display fingerprint reader
- Build: IP68 dust/water resistance and a magnetic snap-on case option
Display upgrades are especially interesting: the 15T reportedly moves from last year’s 120Hz LTPO panel to a faster 165Hz 1.5K LTPS screen. Gamers and heavy users should notice snappier motion and touch responsiveness.
Camera expectations — tweaks over revolutions
On the imaging front, the leaks are less exciting. The telephoto unit is said to reuse the 50MP JN5 sensor from the previous model, and there’s no clear confirmation of an upgraded main sensor or the addition of a new third camera. In short: expect iterative improvements rather than a camera revolution.
OnePlus has used slightly different hardware for China and India before — the 13T and 13s were nearly identical but diverged in battery size and selfie specs — so the final camera lineup could vary by market.
Release timing and availability questions
The 13T landed in April, and the leak points to a similar early-Q2 schedule for the 15T in China. The big unanswered question is global availability: will OnePlus release the 15T (or a regional variant) in India, Europe, and North America, or will it remain a China-focused model like some recent mini handsets?

If it reaches multiple markets, the 15T will face direct competition from the Xiaomi 17 Pro, vivo X300 and likely the Oppo Find X9s. The rumored battery and chipset choices could give OnePlus a competitive edge on stamina and raw performance.
Why this leak matters
Imagine a OnePlus phone that matches flagship performance with multi-day battery life — that’s the promise here. Paired with an ultrasonic fingerprint sensor, IP68 protection and a high-refresh 1.5K display, the 15T could appeal to users who want flagship chops without paying for the most expensive camera hardware.
For now, take the details with a pinch of salt: these are leaks and plans can change before an official launch. Still, early-Q2 timing and the emphasis on battery and display improvements make the OnePlus 15T one of the more intriguing mid-cycle flagships to watch.
