Why Your Old iPhone Is Worth More (or Less) Depending on When You Sell It

I didn't think much about timing the first time I sold an old phone. I'd upgraded, the old one sat in a drawer for a few months, and eventually I looked up how to get rid of it. What I didn't realise until later was that those few months of "getting around to it" had already cost me a decent chunk of what the phone was actually worth.

That's the thing nobody really tells you about selling a used iPhone: the price isn't just about the model or the condition. Timing plays a bigger role than most people expect, and once you understand why, it changes how you think about the whole process.

You'd think a phone loses value at a steady, predictable rate — a bit each month, like a car. In practice, it's lumpier than that. Most of the depreciation happens in bursts, tied to very specific moments, rather than trickling down smoothly over time.

The biggest of these moments, by far, is when a new model gets announced.

Every autumn, when a new iPhone lineup gets revealed, something predictable happens to the resale value of every model that came before it: it drops. Not because the older phones suddenly got worse — they're exactly the same device they were the day before — but because buyer attention shifts almost overnight to whatever's newest.

It's a strange thing to witness if you're paying attention. A phone that held its value reasonably well for the better part of a year can lose a noticeable chunk of that value within days of an announcement, simply because everyone's talking about the next thing instead.

If you already know you're planning to sell, this is probably the single most useful fact to keep in mind: the weeks before a new launch are usually a better time to sell than the weeks after.

Here's a mistake I've seen a lot of people make, myself included, the first time around: assuming that after the initial post-launch dip, prices will bounce back once the hype dies down.

They generally don't. What actually happens is prices keep drifting downward, just more slowly. The dip isn't a temporary blip that corrects itself — it's the start of a longer, steady decline that continues until the next launch cycle repeats the whole pattern again.

So if you're holding onto a phone hoping the market will "recover," it's worth recalibrating that expectation. It almost never does, at least not in any way that makes waiting worthwhile.

Somewhere around six to nine months after a launch, things tend to settle into a more stable rhythm. The initial shock has passed, the newest model isn't newest anymore, and prices for the current generation stop moving around as dramatically.

If you're not in any particular rush and just want to avoid the most volatile stretches, this middle period is generally the calmest window to work with. It's not going to get you the absolute peak price, but it's predictable, and predictable is underrated when you're trying to make a decision without a spreadsheet.

In the weeks leading up to an expected announcement, when leaks and speculation are everywhere, it's tempting to hold out and see what happens — maybe even hope the rumours are wrong and there's no launch this year after all.

In my experience, this is usually the worst time to wait. The market often starts adjusting before anything official happens, simply because enough people are anticipating the same announcement everyone else is. By the time it's confirmed, the value has often already started slipping.

Beyond the launch cycle, a handful of smaller patterns are worth knowing:

None of these are as dramatic as the launch cycle, but they're worth factoring in if your timing is flexible.

Honestly, the answer that holds up best across most situations is simpler than people expect: sooner rather than later. Waiting for a "perfect" moment usually costs more than it gains, because the biggest risk isn't picking a slightly suboptimal week — it's letting months pass while telling yourself you'll deal with it eventually.

If there's a launch coming up in the next few weeks and you already know you want to sell, that's a reasonable moment to prioritise. Otherwise, the version of "waiting" that actually pays off is rare enough that it's not worth building your whole plan around it.

Looking back, the mistake wasn't picking a bad time to sell my old phone — it was not really picking a time at all. It just sat there while the decision quietly kept getting made for me, one month of depreciation at a time.

If you've got an old iPhone sitting around and you've been meaning to look into selling it, the timing lesson is pretty simple: the moment you're actually ready is usually better than waiting for some theoretically perfect one. I ended up using 

 when I finally got around to it, mostly because the whole process fit into an evening rather than turning into a project — but wherever you end up going, the timing advice above holds regardless of who you sell to.
