How Phone Trade-In Values Drop Over Time (And When To Sell)

Smartphones depreciate in value at a surprisingly brutal pace, with many models losing more than half their trade-in value within the first year.

This can be a painful realization if you wait too long to sell. But this decline isn’t random. Phone trade-in values follow a predictable pattern shaped by new model launches, market saturation, and shifting demand.

Once you understand how and when those drops happen, timing your sale becomes a lot easier. So if you’re holding onto a phone and wondering how much value it’s already lost (or trying to figure out the smartest moment to upgrade), read on for a full breakdown of the value-drop trends for iPhone, Android, and Google Pixel.

Why Your Phone’s Trade-In Value Drops So Quickly

Phone trade-in values don’t fall by accident. They drop fast because the entire smartphone market is built around constant upgrades.

Every year, brands like Apple, Samsung, and Google roll out new models. The moment those launches are announced, last year’s phones instantly feel “older,” even if they still work perfectly.

That announcement alone kicks off a chain reaction. Many people rush to sell their current phones to upgrade, flooding the resale market with used devices. At the same time, carriers and retailers push aggressive trade-in deals tied to the new releases, adding even more supply.

And when there are more phones for sale than buyers, prices fall. It’s that simple.

On top of that, technology moves quickly. Newer phones come with better cameras, faster chips, longer battery life, and fresh software features. Over time, those upgrades make older models less appealing to buyers. Software support plays a big role, too. Once a phone stops getting the latest OS updates, its resale value takes another hit because buyers know its lifespan is limited.

There’s also a psychological side to it. People like having the “latest” device, and phones are marketed that way on purpose. Even a perfectly good phone can feel outdated once a newer version is released. And as demand shifts toward newer models, older phones lose their shine, and their value drops right along with it.

The Best Time to Sell Your Phone

Given the predictable nature of the market, there is a clear strategic window for selling your phone to maximize its value. The best time to sell depends on the brand of your phone, as each has its own release cycle.

For iPhone Owners

The consensus among market analysts is that the best time to sell an iPhone is in the weeks leading up to Apple’s annual September keynote. Specifically, the period from late July through August is considered the sweet spot.

During this time, demand for used iPhones is still high, and the market has not yet been flooded with devices from upgraders. Resale prices are relatively stable, and you can get a top-dollar offer before the official announcement of the new models causes a sharp decline.

For Samsung Owners

Samsung usually unveils its new Galaxy S-series phones early in the year, often in January or February. That means the best time to sell your current Galaxy is just before that, typically in December or early January. Selling during this window lets you lock in a higher value before the market fills up with older Galaxy models from people upgrading to the latest release.

For Google Pixel Owners

Google’s Pixel launch typically happens in October, so the smartest time to sell a Pixel is a little earlier, around August or September. At that point, demand is still strong, and prices haven’t dropped yet. Once the new Pixel models are announced, older generations tend to lose value quickly, so getting ahead of that announcement can make a noticeable difference in what you get paid.

What if You Miss the Best Selling Window?

If you miss the prime pre-announcement window, there are still other opportunities to get a decent return, though the value will be lower.

For example, the period from late October to November can be a good time to sell, as holiday shoppers look for deals on secondhand phones as gifts. During this time, demand for mid-range and older phones picks up slightly, as parents and gift-givers search for affordable options. While you will not get the peak prices seen in the summer, you can still capture more value than if you wait until after the holidays.

Another smaller window opens up during tax refund season, from February to April, when consumers with extra cash may be in the market for a phone upgrade. This period sees a modest uptick in demand for used phones, particularly among buyers who prefer to pay cash rather than finance a new device.

However, neither of these periods will offer the peak values seen in the pre-announcement windows. The longer you wait, the more your phone’s value will decline. The key is to act decisively once you have decided to upgrade. Every week you wait, especially in the fall, can translate to a lower trade-in offer.

How to Lock in Your Phone’s Value

One of the best strategies for beating the phone trade-in value drop is to lock in a quote with an online buyback company.

Many reputable buyback services will give you an instant quote for your device and honor that price for a set period, often up to 30 days. This is a powerful tool, especially if you are selling in the weeks leading up to a new phone launch. You can lock in a high price, then wait for the new phone to be released before sending your old one in.

This allows you to get the best of both worlds: you secure a top-dollar offer before the market drops, but you do not have to go without a phone while you wait for your new one to arrive.

The price-lock guarantee is particularly valuable because it removes the risk of market volatility. Once you have locked in your quote, you are protected from any sudden price drops that might occur due to a new product announcement or a surge in supply. This allows you to plan your upgrade on your own timeline without worrying about losing money.

The Role of Device Condition in Trade-in Value

Timing is the most critical factor in determining your phone’s trade-in value, but the condition of the device also plays a major role. A phone with a cracked screen, deep scratches, or poor battery health will be worth significantly less than one in excellent condition.

In fact, a device in faulty condition can be worth as little as 4-8% of its original value, compared to 50% or more for a well-maintained phone of the same age. Using a case and screen protector from day one is the easiest way to preserve its value. When you are ready to sell, presenting a device that is clean and well-cared-for will help you get the full quoted amount.

Getting the Most Out of Your Trade-In

 

Getting the most money for your phone comes down to two things: timing and care.

While every phone loses value over time, those drops follow a pretty predictable pattern. When you know how the market works (and sell during the right window for your specific brand), you can still recover a solid chunk of what you originally paid and put it toward your next upgrade.

The key is acting before prices start to slide. Locking in a competitive quote ahead of major price drops helps you stay in control, even if you don’t send your phone in right away.

FAQs About Phone Trade-In Values

How much value does a phone lose in a year?

A new phone can lose over half of its value in the first year. iPhones tend to lose around 50%, while flagship Android phones from Samsung and Google can lose over 60% in the first 12 months.

What is the best month to sell my phone?

It depends on the brand. For iPhones, August is the best month. For Samsung Galaxy phones, December or early January is ideal. For Google Pixel phones, August or September is the prime time to sell.

Does a phone’s trade-in value drop when a new model comes out?

Yes, this is when the most significant phone trade-in value drop occurs. As soon as a new model is announced, the value of all previous models decreases, often by 10-15% within the first month alone.

How can I get the most money for my old phone?

To get the most money, you should sell your phone in the month or two before the new model is announced. Additionally, using an online buyback service that offers a price-lock guarantee allows you to secure a high value and then send your phone in after you have received your new one.

Is it worth trading in a phone that is two years old?

Yes, a two-year-old phone still holds significant value. The 18-24 month mark is often a sweet spot for upgrading, as the trade-in value is still substantial enough to make a meaningful contribution toward a new device. Waiting beyond two years can result in a much steeper decline in value.
