The Action Button retired the iPhone’s oldest surviving control, the mute switch, and replaced it with a question: what do you want this button to do? Camera, torch, voice memo, a Shortcut that texts your ETA home, silent mode for the traditionalists. Introduced on the 15 Pro generation and spreading across the lineup since, it is the most personal piece of hardware on the phone, and the used market now offers it at a decidedly impersonal discount.

Why second-hand is not “second best”
The Action Button is solid-state simplicity: a press-and-hold customisable control wired into iOS at the system level. On a used 15 Pro it configures, remaps and runs Shortcuts exactly as on launch day, buttons of this construction outlive phones. The workflows are where it shines: camera launched before the moment passes, torch without fumbling, a recording started discreetly in a meeting, focus modes toggled on a commute. One press, hundreds of times a week, compounding convenience.
For most buyers the button arrives as part of the broader 15 Pro package, titanium build, USB-C, ProMotion, the full modern kit, which the used market now prices as simply “last generation”. The most personal button in phones, bundled into the most rational purchase in phones.
Apple finally asked what you want the button to do, and the used market asks half as much to answer.
The savings are real
15 Pro-generation models carry proper refurb discounts, 20-60% off launch pricing that was, at the time, the top of Apple’s range. Buyers targeting the Action Button get titanium flagships at aluminium money, with years of update runway. Later standard-model generations that inherited the button widen the choice further down the price curve.
New vs used, side by side
| Brand new | Used / refurbished | |
|---|---|---|
| Action Button access | Current lineup | 15 Pro onward, used pricing applies |
| Customisation | Full Shortcuts integration | Identical, it is system software |
| Button durability | Built to outlast the phone | Same hardware, one press on arrival verifies |
| Package around it | Titanium, USB-C, ProMotion | The same package at 20-60% off |
| Warranty | Apple standard | Seller warranty + possible residual Apple coverage |
The five-minute checklist before you pay
- Generation floor: 15 Pro and Pro Max debuted the button; later generations spread it wider. Standard 15s and earlier carry the mute switch, listings conflate them regularly.
- Button press test on arrival: configure it to torch, press-and-hold, done, hardware and software verified in ten seconds.
- The full recent-Pro inspection: ProMotion scroll test, every camera lens, USB-C charge and data, the button rides on a flagship worth checking end to end.
- Battery health 85%+: recent generations should deliver it; demand the figure regardless.
- Residual Apple warranty check: models this recent often carry months of factory coverage, the serial number tells.
- The universal checks: IMEI clean, Activation Lock off, unlocked, warranty stated.
You have more protection than you think
Action Button models are young enough that protections stack three deep: possible residual Apple warranty (check the serial), the refurbisher’s own cover, and beneath both the Australian Consumer Law’s guarantees from any business seller. A non-functioning button on a phone this recent is an acceptable-quality failure, plainly remediable. Verify with one press on arrival, keep the listing screenshot, pay on-platform, the routine that makes every layer enforceable.

Red flags to walk away from
- “Action Button” claimed on standard 15s or any 14, those carry mute switches.
- Button described as “sticky” or “sometimes responds”, switchgear faults only travel one direction.
- Recent flagships missing battery figures or IMEI offers.
- Prices dramatically under the recent-Pro market, scam gravity concentrates on new tiers.
- Off-platform payment, always.
Frequently asked questions
Which used iPhones have the Action Button? The 15 Pro and 15 Pro Max introduced it; subsequent generations extended it across the range. Anything older, including standard 15s, has the classic mute switch.
What can the button actually do? Stock options include silent mode, camera, torch, voice memos, focus modes, magnifier and translation, and Shortcuts opens it to effectively any workflow you can build: messages, smart home scenes, logging apps, multi-step routines.
Do traditionalists lose the mute switch? No, silent mode is the button’s default assignment, replicating the switch exactly for those who want nothing new.
Is the button a reason to buy this generation used? It is the garnish; the meal is the 15 Pro package, titanium, USB-C, ProMotion, at 20-60% off. The button makes a rational purchase slightly delightful.
The bottom line
The Action Button personalised the iPhone’s hardware, and depreciation has now personalised its price: 15 Pro-generation flagships at 20-60% off, button and all. Confirm the generation, press-test on arrival, check for residual factory warranty, and assign the most personal button in phones to whatever your day presses most.
