While most smartphone brands have moved on from compact flagships, OnePlus seems keen on keeping the category alive. The company introduced the OnePlus 13T last year as a smaller alternative to its flagship OnePlus 13, packing top-tier specs into a more compact form factor. Now, a new leak suggests OnePlus is gearing up to launch its successor.

According to a recent post from reputed tipster Digital Chat Station on Weibo (via Playfuldroid), OnePlus may announce the OnePlus 15T in April, around the same time the company unveiled the OnePlus 13T last year. Although the company has yet to make anything official, the leaker has already shared a few key details about the device.

Like its predecessor, the OnePlus 15T is tipped to pack a 6.3-inch display with a 1.5K resolution, but with support for a higher peak refresh rate of 165Hz. The device could also get an upgraded 3D ultrasonic fingerprint sensor for faster, more accurate unlocks.

The leak further adds that the OnePlus 15T will retain the same 50MP JN5 telephoto camera as last year’s model, though details about the main and selfie camera remain unclear. The battery is expected to see the biggest upgrade, jumping from 6,260mAh on the OnePlus 13T to over 7,000mAh, with OnePlus reportedly aiming to go as high as 7,500mAh.

The OnePlus 15T is expected to feature Qualcomm’s latest flagship Snapdragon chipset. However, it isn’t clear whether OnePlus will equip the device with the Snapdragon 8 Elite Gen 5 or opt for the non-Elite Gen 5 SoC.

There’s no word on international availability at this point, but it’s safe to assume that OnePlus may not offer the device in all markets. That’s because the company only launched its predecessor in China, and released a slightly downgraded version in India, dubbed the OnePlus 13s, with a smaller battery and weaker selfie camera.

Apple’s new Upgrade program launches on Tuesday with major changes

Apple's new leasing program might drop AppleCare coverage from the bundle.

iPhone 17 Pro Max

Buying your next Apple device could soon look like leasing a car. Apple is launching its new Apple Upgrade program on Tuesday, July 28, replacing new enrollments in the long-running iPhone Upgrade Program with a lease-based option that covers iPhones, iPads, Macs, and Apple Watches.

Backed by Klarna, the program is designed to lower the upfront cost of Apple's premium devices, but it is also raising questions about whether you'll actually own what you're paying for.

Setting up your dorm desk? These are the phone stands I’d actually spend my money on

From a $2 folding stand to a three-in-one Apple charging dock, these are the phone stands worth setting up this semester.

A phone stand is one of the smallest purchases on any back-to-school list, but it's also one of the easiest to get wrong, especially since there are dozens of options available on Amazon. A good phone stand is one that does its job well and, more importantly, doesn't put much of a dent in your budget.

This is one of those product categories where you don’t need to spend big, unless a MagSafe dock or a multi-device charging stand is genuinely useful for your desk or dorm setup. That is why this list begins with the most affordable options and works its way up to the more expensive ones. From a two-pack that costs about as much as a coffee to a three-in-one Apple charging station, I picked eight of Amazon's best-reviewed phone stands worth considering this back-to-school season.

I picked four wireless chargers so you can stop making your iPhone, AirPods, and Apple Watch fight over one dorm outlet

The best back-to-school wireless chargers for dorm desks, study spaces, and travel

Computer, Electronics, Laptop

A dorm-room desk can disappear surprisingly quickly beneath a laptop charger, phone cable, Apple Watch puck, and the growing collection of adapters required to power them all. Add textbooks and other academic materials, and finding enough room to study becomes the first assignment of the semester.

A wireless charging stand can consolidate several of those cables into one station. It also gives your phone a dedicated place to sit, which helps when you are checking the time or watching a lecture. Every charger here still needs one connection to the wall. So finding a peripheral that works with all of your gadgets isn't just convenient, it's smart. I picked four models ranging from an inexpensive two-device stand to a fast 25W wireless charger capable of powering an entire Apple setup.
