How much is my phone worth?

We’ve all asked it. Usually while staring at a drawer full of old phones or eyeing up a shiny new upgrade.
So how much is your phone actually worth? The answer depends on a few key factors, including the make and model, storage size, condition, network status, and current market demand.
This guide explains everything you need to know about how phone values are calculated and how to quickly turn your old device into cash.
Let’s get started.
What affects phone trade-in value?
Phone prices are decided by a variety of factors. There are a few key things that decide how much your mobile is worth today.
The model
Put simply, newer models are worth more. A recent iPhone or Samsung will usually fetch a higher price than something released a few years ago.
That being said, older phones still have value. Even faulty or tired phones can be recycled and sold for cash.
Storage size
As with the release date, it really is as simple as more storage = more money. A 256GB phone will almost always be worth more than the 64GB version of the same phone.
Wondering how to check your phone’s storage size? This information can often be found in the settings app on your phone.
For iPhone:
- Open Settings.
- Tap General.
- Select About.
- Look for capacity or storage, and you’ll find the total storage size of your device.
For Android:
- Open Settings
- Scroll down and tap Storage (sometimes under device care or about phone).
- You’ll see the total storage capacity and how much is currently used.
Typically, it doesn’t matter how much storage you’ve used when selling, as your phone will be reset to factory settings.
Condition
Phones in great condition score higher prices. Scratches, cracked screens, or battery issues can knock the value down.
When selling with Mazuma, it’s a simple process of choosing between three condition types; ‘Excellent’, ‘Good’ and ‘Faulty’. Be sure to read these carefully when selling your device, as this will ultimately impact how much you get paid.
Network
Unlocked phones are usually worth more. They work on any network, which makes them easier to reuse.
Network-locked phones can still be sold in most cases but be sure to check the exact phone on our website, as in some cases only unlocked versions are accepted.
While this primarily affects older models, verifying your device’s lock status is essential to ensuring you get the most value from it.
We accept phones from O2, Vodafone, EE, and Three.
Market demand
Phone prices move often. New releases, seasonal demand, and tech trends all affect what your phone is worth right now.
Say there’s a new iPhone released, this may cause the market prices of all other iPhones to shift, as more people sell to afford an upgrade.
If you’re wondering, ‘Why is my phone worth less than last month?’, this is why.

Where is the best place to sell your phone in the UK?
There are many options to choose from. But it’s important to do your research so you know exactly what to expect.
Selling privately
This can offer high prices, but they come with risks including slow sales, time wasters, payment issues, and lack of protection. It’s not for everyone.
Trade-in retailers
Convenient, yes. But trade-ins often pay less and lock you into vouchers or upgrades.
