iQOO is set to launch the iQOO 15 Ultra in early February, and the company has started sharing details about what sets it apart from other flagship phones.
According to iQOO’s product manager, the iQOO 15 Ultra will be the first smartphone to feature what the company calls “Super-Sensitive Touch Shoulder Buttons.”
As the name suggests, these are touch-based shoulder controls placed on the left and right sides near the main button area. So when the phone is held horizontally, fingers naturally rest on these zones.
iQOO says that popular FPS games will support built-in adaptive presets for the shoulder buttons. The controls also offer advanced mapping options, including combo actions and shortcut functions, allowing users to go beyond basic tap inputs.
iQOO 15 Ultra shoulder buttons has leading sampling rate
On the hardware side, the shoulder buttons operate with a 600Hz touch sampling rate, which iQOO describes as industry-leading. The system uses dual independent control chips, enabling each shoulder button to send inputs separately. This design is intended to minimize input delay and improve accuracy.
The company has also added a new anti-sweat algorithm to address issues that commonly appear during longer gaming sessions.
Unlike traditional press-type shoulder buttons, the iQOO 15 Ultra’s implementation avoids mechanical components altogether. Paired with a linear motor, the phone simulates tactile feedback that remains consistent over extended use.
Since there are no physical moving parts, iQOO says the buttons do not suffer from mechanical wear. Great, and it also means a virtually unlimited lifespan. The flush design also helps improve resistance to sweat and water while reducing the chances of dust and dirt buildup. Another advantage is the lack of reset delays, which helps keep latency low and allows for smoother continuous inputs.
