Quick Answer
iPhone Duo unlocks more slowly than iPad mini (A17 Pro) in Mediastorm's Touch ID comparison.
The review shows the difference without reporting a measured delay in milliseconds.
Duo uses Touch ID in its side button and does not have Face ID.
Apple Watch unlocking is another option if you find the fingerprint step inconvenient.
iPad mini Unlocks First
A surprisingly ordinary interaction exposes one of iPhone Duo's small frustrations: unlocking it. In the side-by-side comparison, the iPad mini (A17 Pro) finishes unlocking before Duo. The reviewer specifically calls out the iPad as the faster device.
Both use a fingerprint sensor built into a physical button: the side button on Duo and the top button on iPad mini. The comparison establishes the slower unlock experience, but does not identify its cause.
The practical annoyance: unlocking is something you repeat throughout the day. A short extra wait can stand out more often than a difference in a demanding benchmark. This is a separate part of the experience from Duo's CPU performance.
Apple Watch Gives Duo Another Unlock Option
If you already wear an Apple Watch, Duo supports unlocking through the watch. The reviewer recommends it as a more comfortable alternative to repeatedly using the fingerprint sensor.
That makes sense for someone who misses the convenience of Face ID: it gives you another way into the phone without relying on a fingerprint scan every time. Apple confirms Apple Watch unlocking in its iPhone Duo announcement.
