Background: Apple’s Shift from Qualcomm
For most of the iPhone’s history Apple relied on Qualcomm (and briefly Intel) for cellular modems. Starting with the iPhone 16e in February, Apple began shipping devices with its own C1 modem, followed by the iPhone Air with the C1X modem and the M5 iPad Pro.
Why In‑House Modems Matter
Beyond the well‑known legal battles—Apple sued Qualcomm for $1 billion in 2017 and settled in 2019—owning the modem gives Apple full control over hardware design, integration timelines, and power‑efficiency strategies.
- Tighter hardware‑software integration
- Reduced dependence on external supply‑chain constraints
- Potential for custom features unavailable on third‑party chips
The “Limit Precise Location” Feature in iOS 26.3
iOS 26.3 introduces a user‑facing setting that lets you restrict how accurately your device reports its location to carriers and apps. While any privacy‑enhancing option is welcome, this is the first feature that directly leverages Apple’s own modem.
Immediate Benefits for Users
- Improved privacy: less precise cell‑tower data shared with carriers.
- Battery savings: the in‑house modem can manage power more efficiently.
- Better connectivity: tighter integration can lead to faster hand‑offs and more stable signal.
Future Outlook
When Apple’s entire iPhone lineup runs on its own modems, we can expect a wave of new capabilities—ranging from advanced network‑optimisation algorithms to novel privacy controls—plus incremental gains in battery life and signal reliability.
In short, the “limit precise location” toggle is a glimpse of what’s to come as Apple fully embraces its modem strategy.
