Phones lose value fast for one main reason: a new model turns up every year, and the moment it does, yours becomes "last year's phone" in the eyes of buyers. On top of that annual reset, everyday wear, battery ageing, falling launch prices on newer tech, and a flood of trade-ins around each launch all push the price of your handset down. Most of the drop happens in the first year, then it slows.
We buy and sell phones every day, so we watch this happen in real time. Here is why phones depreciate so quickly, which ones fall hardest, and how to stop your device quietly losing value while it sits in a drawer.
Why do phones lose value so quickly?
A phone is worth what the next person will pay for it, and that number falls the second something newer and shinier exists. The annual release cycle is the engine behind most phone depreciation. Every year brings a new flagship, the previous generation drops a rung, and the one before that drops again.
There is more to it than the calendar, though. A few forces stack up at once:
- The new-model effect. A launch instantly reframes your phone as older, even if nothing about it changed. Demand shifts to the new thing.
- Supply spikes at launch. Everyone upgrading dumps their old handset around the same few weeks, so the second-hand market floods and prices soften.
- Battery and wear. Batteries degrade with every charge, and scuffs and cracks accumulate. The next owner prices in the cost of putting that right.
- Falling reference prices. When the newest model offers more for the same money, it drags the whole range down behind it.
- Software horizon. Once a phone stops getting updates, its useful life has a visible end date, and buyers pay less for a shorter runway.
Here's the thing worth knowing: none of these are about your phone getting worse. It still does everything it did the day you bought it. The value drops because the market around it moved, not because the device failed.
How fast do phones actually lose value?
The curve is steepest at the start. A phone gives up the biggest chunk of its value in the first twelve months, then the decline flattens out. That front-loaded drop catches people out, because it feels like your nearly-new phone should still be worth nearly-new money. It isn't.
| Age of phone | Roughly what happens to value |
|---|---|
| 0 to 6 months | Slides from new-price fast, especially once the box is opened and it is "used" |
| 6 to 12 months | Keeps falling, with a sharp step down around the next model's launch |
| 1 to 2 years | Decline slows to a steadier, gentler pace |
| 2 to 4 years | Fairly stable, now driven mostly by condition and battery health |
| 4 years and beyond | Low and flat, though still worth more than nothing if it works |
Read that top to bottom and the lesson is simple. The longer you wait, the less each extra month costs you, but the first year is brutal. Let's be honest, most of us hang on to a phone long past the point it was worth selling, telling ourselves we will get round to it.
Which phones lose value fastest?
Not all phones fall at the same rate, and the gap is bigger than most people assume. This is the single most useful thing to understand if you care about resale value.
Android handsets, as a broad rule, depreciate faster than iPhones. The reasons are concrete: shorter software support on many models, a crowded market with constant new releases, and weaker second-hand demand for older Android devices. An iPhone holds a much larger slice of its original price two or three years on, largely because Apple supports its phones for years, so an older one still feels safe and usable.
Within any brand, the same pattern repeats. Premium and Pro models hold value best, because the cameras, displays and storage that command a premium new keep them desirable second-hand. Cheaper and mid-range models give up value fastest, since they launched lower and have a shorter desirability window. Worth knowing if you are choosing your next phone with resale in mind.
Here is an insight the flashier value guides skip: a higher launch price does not mean a bigger loss. A phone that starts expensive but stays in demand can lose a smaller share of its value than a cheaper phone nobody wants second-hand. Retention is about desirability, not the sticker price you paid.
The mistake that costs people the most
The biggest avoidable loss is not choosing the wrong phone. It is doing nothing. A phone left in a drawer does not pause its depreciation, it keeps sliding while you are not looking, and it misses every launch-timed window to sell well along the way.
We've all done it. The upgrade arrives, the old phone goes in the drawer "just in case," and eighteen months later it is worth a fraction of what it would have fetched the week you replaced it. The phone sat in your drawer is not holding its value, it is quietly losing it. If you are going to sell, the value-preserving move is to do it sooner rather than later, ideally before or around the next launch when demand and prices are still up.
How to protect what your phone is worth
You cannot stop depreciation, but you can control how much of the price you actually walk away with. A few things genuinely move the number:
- Sell sooner, not later. The first year is the expensive one. If you have upgraded, the old phone is depreciating in a drawer for no reason.
- Keep it in good nick. A case and screen protector cost little and protect real resale value. Condition often swings the price more than the model name on older phones.
- Mind the battery. A worn battery drags the quote down, because the next owner faces a replacement cost. Worth knowing before you write a tired phone off, though, plenty of them still quote better than expected.
- Sell it unlocked. An unlocked phone appeals to more buyers, so it holds value better than a network-locked one.
- Get an accurate quote, not just a headline. This is where the trade-in industry plays games, so it is worth naming.
That last point matters more than the rest combined. Anyone can advertise a big "we'll pay you £X" number to win the click, then quietly "downgrade" it once your phone is in their hands. A headline price is cheap. The number that actually lands in your account is the product.
Reboxed is built to close that gap. Our TechCheck® asks the right condition questions up front, so the quote you accept is the quote you get. To be straight with you, downgrades can still happen, but around 90% of the time that is because someone genuinely mis-graded their phone at the self-assessment stage, usually over-rating its condition, not because we moved the goalposts. Grade it accurately and there are no nasty surprises. If a device honestly does not match what was declared, you get a revised offer to accept or decline, posted back free if you decline. No faff. You can check what your phone is worth in about 30 seconds, and the quote holds for 14 days, so nothing is rushed. If you want to see the process first, here's how it works.
Where Reboxed isn't the right choice
If your one goal is the absolute highest number and you do not mind the graft, selling privately can net more, especially on a recent, pristine, unlocked flagship that keen buyers will chase. List it well, field the messages, and carry the risk of returns and chargebacks, and a patient private seller can beat a trade-in quote on the headline figure. That is the truth, and we would rather say it than pretend otherwise. Trade-in suits people who value a fair, guaranteed price paid quickly over chasing the last few quid. If that is not you, sell it privately with our blessing.
Make your old phone count for something
One more thing worth knowing. A phone gathering dust is wasted value and wasted materials, not just a smaller quote down the line. Rehoming it beats hoarding it. At Reboxed, every device rehomed plants 5 trees, part of a mission to rehome 100 million devices, so passing your old phone on does a bit of good as well as freeing up some cash.
Depreciation is a fact of life with phones. Losing more of it than you had to is the avoidable bit. See what your phone is worth in 30 seconds and sell it while it still has value to give.
FAQ
Why do phones lose value so fast?
Mostly because a new model launches every year, which instantly reframes your phone as older and floods the second-hand market with trade-ins. Battery ageing, everyday wear, falling prices on newer tech, and a fixed software-support window add to it. The device has not got worse, the market around it has moved on.
How much value does a phone lose in the first year?
The first twelve months are the steepest part of the curve, when a phone gives up the biggest share of its value, with a sharp step down around the next model's launch. After the first year or two the decline slows to a gentler pace driven mostly by condition and battery health.
Do iPhones lose value slower than Android phones?
As a rule, yes. Long software support and steady demand mean iPhones keep a larger slice of their original price after two or three years than most Android handsets, which tend to depreciate faster because of shorter update windows and weaker second-hand demand.
How do I stop my phone losing value in a drawer?
You cannot pause depreciation, but you can stop wasting it. Sell sooner rather than later, ideally before or around a new launch, keep the phone in good condition and unlocked, and get an accurate, guaranteed quote rather than trusting a headline number that can be chopped on arrival.
Is it worth selling an old phone that has lost most of its value?
Usually yes. Even an older or worn phone that still works is worth more sold than sat in a drawer, where it keeps losing value and takes up space. A lot of phones people assume are worthless still quote better than expected, especially once battery and condition are assessed properly.
