Apple developed an internal prototype of a stubby Apple Pencil designed specifically for its upcoming foldable iPhone Ultra, though hardware hurdles will likely keep the accessory out of the first-generation release, according to Bloomberg’s Mark Gurman.
Apple Engineers a Shorter Stylus for Unreleased Foldable Hardware
Compact Proportions and Magnetic Attachment Mechanics
According to Bloomberg’s Mark Gurman, Apple engineers built and tested a shortened version of the Apple Pencil tailored to the proportions of the unannounced iPhone Ultra. Unlike traditional styluses built for larger iPad displays, this prototype featured a compact body designed to match the shorter height of the foldable device. The concept included magnetic side attachment for storage and induction charging, mirroring how styluses attach to current iPad models.
Bulk Interference and Flexible Display Vulnerabilities
Despite completing internal testing, the project faces structural obstacles that threaten its commercial debut. Gurman reports that the magnetic side placement creates physical bulk that interferes with opening the foldable phone smoothly. Furthermore, engineers encountered durability concerns regarding the fragile nature of flexible internal screens. Unlike rigid glass panels found on iPads, foldable displays risk developing permanent pressure marks or scratches from repeated stylus use.
Reversing Jobs Era Dogma and Precedents from Samsung
The potential inclusion of a stylus directly challenges the historical design philosophy established by Steve Jobs during the introduction of the original iPhone in 2007, where he famously dismissed the need for a stylus. However, Apple later abandoned that stance by releasing the Apple Pencil for iPad lineups. Samsung previously navigated similar engineering hurdles with its Galaxy Z Fold series by introducing retractable pen tips designed to limit screen pressure, though newer iterations have altered compatibility.

Autumn Production Timelines and Material Science Bottlenecks
While an iPhone Ultra stylus would provide distinct advantages for hand-written notes, document signing, precision drawing, and mobile photo editing on its expansive 7.8-inch internal display, Apple prioritizes overall structural integrity for the inaugural foldable hardware. Current supply chain reports indicate the iPhone Ultra remains on track for production and a scheduled autumn launch, while the specialized stylus stays confined to testing labs until material science advances enough to prevent pressure damage.
