The OnePlus 15T is shaping up to be the compact flagship phone many users have been waiting for. A new leak out of China reveals it could pack serious hardware into a smaller form factor, plus one surprise: a monster-sized battery.
OnePlus 15T leak hints at flagship specs in a small shell
According to Weibo tipster Smart Pikachu, the OnePlus 15T (possibly sold as the OnePlus 15s globally) will feature a 6.3-inch display, putting it firmly in the “compact” category by today’s stretched standards.
Inside, it’s rumored to carry the Snapdragon 8 Gen 5 “Elite” chipset and a metal frame. The phone may also introduce multifunction buttons that double for AI features or camera controls, making it more versatile than expected.
7,000mAh battery could crush the competition
Here’s where it gets wild. The OnePlus 15T is reportedly going to pack a battery larger than 7,000mAh in a phone this size, which is almost unheard of.
For context:
- OnePlus 13s: 5,850mAh
- iPhone 17 (base model): unknown, but likely smaller
- Galaxy S26 Pro: expected under 5,500mAh
- Pixel 10: battery details still under wraps
If true, this battery gives the 15T an easy lead in the battery life department.
Ultrasonic fingerprint sensor adds premium touch
Another quiet upgrade could be in the fingerprint tech. The tipster claims the OnePlus 15T will feature an ultrasonic sensor, a clear jump over the optical reader used in the 13s. This would bring improved accuracy and unlock speed, even with wet or dirty fingers.
OnePlus 15T enters a crowded field, but with purpose
There’s no shortage of competition in this segment. Apple’s base iPhone 17 and Samsung’s Galaxy S26 Pro are both expected to target the same user base. But OnePlus seems to have found a niche by combining compact size with a huge battery, something no one else has really done well.
Big battery, small frame, OnePlus might have a winner
In an era of phones that feel more like tablets, the OnePlus 15T could hit a sweet spot: pocketable power, all-day battery, and high-end performance. That’s the kind of combo that turns heads and converts users.
It’s not official yet, but the wait might just be worth it.
