OnePlus is set to expand its latest smartphone lineup with the introduction of the OnePlus 13T, confirmed for launch later this month in China. Positioned as a brand-new mid-range offering within the OnePlus 13 family, this device is already generating buzz, particularly for its compact design paired with an impressively large battery exceeding 6,000 mAh. Adding to the anticipation, OnePlus has officially confirmed a significant design change: the signature Alert Slider, a long-standing feature cherished by users, will be replaced by an entirely new button dubbed the 'Quick Key'. This shift was revealed by OnePlus China president Li Jie Louis via the Chinese social media platform Weibo, signaling a potential new direction for the brand's physical controls. The newly introduced Quick Key, showcased in a teaser poster shared by Mr. Louis, is a small button situated on the left side of the OnePlus 13T (when viewed from the front). This move seems to echo Apple's recent replacement of the Ring/Silent switch with a programmable Action Button on newer iPhone models. Mr. Louis positions the Quick Key as a distinct upgrade over the traditional Alert Slider. Its functionality is expected to encompass the core features of its predecessor while adding enhanced capabilities. Specifically, the Quick Key will allow users to seamlessly switch between different alert modes, including:MuteVibrationRingingBeyond replicating the Alert Slider's primary function, the Quick Key introduces a layer of customization. It features a custom function designed to "facilitate easy switching of choices in a series of operations." Mr. Louis described this as "very practical" and hinted at an "interesting function" integrated into the button, promising more details will be unveiled during the official launch event. This suggests users might be able to assign specific shortcuts or actions to the Quick Key, enhancing the phone's usability. Further details shared by the OnePlus executive shed light on the phone's overall design philosophy and internal hardware. The OnePlus 13T is confirmed to feature a small, flat screen, a choice driven by company research focused on optimizing the in-hand feel and user comfort for a more compact device. Despite its smaller stature, the phone doesn't compromise on battery life. It incorporates a battery with a capacity exceeding 6000mAh, leveraging OnePlus' advanced Glacier battery technology. This technology utilizes a silicon-carbon anode and a sophisticated design to achieve a high-density battery that remains compact, offers superior thermal management, and promotes longevity. While OnePlus confirms 6000+ mAh, leaks suggest the specific capacity might be 6,200mAh, complemented by rapid 80W fast charging capabilities. Rounding out the anticipated specifications, the OnePlus 13T is tipped to be a powerhouse in a small package. Rumors point towards the inclusion of the potent Snapdragon 8 Elite System-on-Chip, ensuring flagship-level performance. The display is expected to be a 6.31-inch AMOLED panel featuring a sharp 1.5K resolution and a smooth 120Hz refresh rate. For photography, the device could sport a capable camera system comprising a 50MP main rear sensor paired with a 50MP telephoto lens offering 2x optical zoom. As the launch approaches, the OnePlus 13T is shaping up to be a compelling option for users seeking a high-performance, long-lasting smartphone experience in a more manageable, compact form factor, albeit with a notable departure from the familiar Alert Slider.
