Overview

When Apple introduced the original 12.9-inch iPad Pro (A1584/A1652) in late 2015, it established a new category for large-format iOS tablets. Driven by the dual-core A9X processor and M9 coprocessor, it paired a high-resolution 2732 x 2048 Retina panel with a four-speaker audio setup, Smart Connector, and active stylus support via the first-generation Apple Pencil. If you are examining this model on our dedicated device page, it remains an intriguing secondary device, provided you understand its physical repair hurdles and performance boundaries.

Design and build

The original 12.9-inch iPad Pro features a slim aluminum unibody chassis that feels remarkably rigid despite its expansive footprint. Framed by classic bezels, it houses a physical Home button with integrated Touch ID. The quad-speaker configuration intelligently redirects audio orientation based on how you hold the device, filling small rooms with sound performance that outclasses many current entry-level slates.

However, the massive display uses a laminated design where the front glass digitizer, touch layer, and liquid crystal panel are fused into a single fused assembly. While this eliminates air gaps and improves Apple Pencil accuracy, it means a minor hairline glass crack usually requires replacing the entire screen panel stack.

Everyday performance

For basic daily duties—such as reading sheet music, watching streaming video, browsing desktop-class web pages, or running lightweight drawing apps—the A9X chip handles workloads well enough. The massive 12.9-inch screen estate is its primary selling point, offering comfortable split-screen viewable space for dual documents or reference images.

Where it shows its age is in heavy modern multitasking and intensive creative software. Modern iPadOS software builds demand higher memory bandwidth and multi-core performance than the A9X architecture can provide. Expect occasional frame drops, app reloads when switching contexts, and elevated chassis warmth when running graphics-heavy tools.

Battery, durability, and longevity

The large dual-cell battery inside this chassis was designed to push both the dense 2732 x 2048 display panel and the active audio drivers. Over years of charge-discharge cycles, original batteries inevitably experience reduced capacity, shortened runtimes, and unexpected power cutoffs under high system load.

Swapping the battery requires heating the perimeter adhesive to carefully pry open the fused screen. Because the display cables and home button ribbon cable sit close to the edge, opening the chassis demands patience to avoid tearing sensitive interconnects.

Common issues owners hit

Several specific hardware bottlenecks frequently affect long-term owners:

• Fused Screen Damage: Dropping the tablet often results in cracked glass. Replacing it requires a full fused display assembly.
• Paired Home Button / Touch ID: The Home button flex cable is cryptographically linked to the logic board. Tearing this cable during a screen teardown permanently disables Touch ID biometric authentication.
• Charging Port Wear: Repeated cable insertion wears down the Lightning port contacts over time, leading to intermittent charging behavior.
• Swollen Battery Strain: Heavily aged cells can swell internally, placing dangerous upward pressure against the back of the LCD display.

Who it's for

This 1st Gen 12.9-inch iPad Pro is best suited for users who want a large display on a budget for narrow, specialized tasks: displaying sheet music on a stand, casual media playback, or using it as a secondary desktop reference monitor. It is less ideal for power users who require fast processing for heavy multi-layer illustration or complex mobile video editing.

Bottom line

The original 12.9-inch iPad Pro remains a notable hardware landmark. While its gorgeous screen and four-speaker audio setup give it lingering appeal, its complex display assembly and glued internal layout mean long-term maintenance requires a delicate touch.
