Phones lose value at different speeds. Some models hold steady for longer, while others drop quickly once a newer model arrives or demand shifts. If you are thinking about selling your phone, the timing can make a real difference.
This guide explains why phone values fall, which types of phones usually hold value best, and how to avoid waiting until your quote has already dropped.
Why phones lose value
A phone starts losing value as soon as newer models, better offers, or fresh stock enter the market. The biggest changes usually come from a few simple things:
- a new model launch from Apple, Samsung, Google or another major brand
- lower demand for older storage sizes or colours
- visible wear, battery ageing, screen marks or repair history
- retailers discounting the same model new or refurbished
- seasonal demand, especially around launch periods and Christmas
That does not mean every phone falls at the same speed. Brand, model, storage and condition all matter.
iPhones usually hold value well
iPhones tend to keep stronger resale value because demand stays high for several years. Recent Pro and Pro Max models are usually the strongest, especially when they have popular storage sizes and are in good condition.
The biggest risk is waiting too close to the next iPhone launch. Once a new range appears, older models often become easier to find second-hand, which can push values down. If you are already planning to upgrade, it is worth checking your price before launch season rather than after it.

Samsung flagships can still do well
Samsung Galaxy S and Ultra models can hold good value, especially newer flagship devices with higher storage. The gap between models can be bigger than people expect, though. A recent Ultra model in excellent condition will usually perform much better than an older mid-range phone.
Condition makes a big difference with Samsung phones. Screen marks, back glass damage, battery issues and camera faults can all pull the quote down. If your phone is still working well, it is usually better to sell it before small faults turn into bigger ones.

Google Pixel, HONOR, OPPO and Motorola values vary more
Google Pixel phones, HONOR, OPPO and Motorola devices can still be worth selling, but their values often move more sharply. Demand depends heavily on the exact model, age, storage and how easy it is to resell.
Newer Pixel Pro models and selected premium devices usually do better than budget ranges. Entry-level phones can drop faster because new prices are already lower and there are more alternatives on the used market.
That is why model selection matters. Two phones from the same brand can have very different trade-in values even if they look similar.
Storage and condition matter more than people think
Higher storage can help, but only when the model itself is still in demand. A higher-storage phone with heavy damage may still be worth less than a lower-storage one in clean condition.
Before you sell, check the basics:
- screen condition
- back and frame marks
- battery health where available
- camera, speaker, charging and buttons
- whether the phone powers on and stays on
- whether it is unlocked or tied to a network
Being honest about condition helps avoid delays and revised quotes later.
When should you sell?
The simple answer: sell when you know you no longer need the phone. Waiting for a better time rarely helps unless you are only a few days away from a known offer or event.
Values normally fall over time. Launch periods, heavy retail discounts and new refurbished stock can speed that up. If your phone is sitting in a drawer, checking the value now is usually better than guessing later.
