Data Driven Hacks to Skyrocket iPhone Trade-in Values
When Apple takes the stage every year to launch the new iPhone there is a flurry of smartphone owners frantically upgrading. As our data will show you, going into this process without a plan to navigate the 30+ buyback options could cost you well over half of what your old iPhones genuinely worth.

4 Factors That Impact Trade-In Values
BankMyCell’s iPhone trade-in pricing feed analysis has highlighted four trade-in pitfalls that will bleed your iPhone’s value. This study will not only provide advice; it will provide real numbers on what you stand to lose by not overcoming these pitfalls:

In the online trade-in market alone, there are dozens of buyback options, and we price checked over 30 of them. We found well-known carriers and in stores solutions typically offer much less than independent online stores, it’s worth comparing, and this is why:
Online Only:

- Apple: consumers would lose $130 (23% loss) of their iPhone X value selling directly to the brand’s trade-in service.
Solution: Some lesser-known stores tend to offer the best prices, shop around! You can get peace of mind by checking their customer reviews on sites like Trustpilot or SiteJabber – confirming chances of them being a hidden gem!
Why? You can get paid more and most importantly avoid payment in store credit restricting your spend. Plus, you get to choose price lock timescales and shipping options to suit you.
It’s not as black and white as having a broken iPhone trade-in price or a working iPhone price. There are three prices you can get before a device gets classed as broken, e.g. where screens/frames are cracked, and the device has hardware or software issues. Well-kept phones that are mint condition, phones that have a couple of marks and phones with cosmetic damage like scratches, dents, marks.
Key Statistics:
- Biggest money loss: Consumers can lose up to $100 on a scratched iPhone X or XS.
- Biggest percentage difference: Consumers can lose up to 34.9% of an iPhone 7’s value if it’s scratched.
- Typical cosmetic damage loss: Average iPhone owner could lose 23.0% of its value for having scratches, the difference in quotes range from 11.1% to 34.9% depending on the model.
- 2017-2018 Models: Consumers could lose 14.9% on average on an iPhone 8 or higher.
Solution: Before you get your new iPhone, buy a case and screen protector to put on straight away. Not only will it save you on repair costs, but it can also skyrocket your trade-in value later down the line.
Why? When you sell, pop off the screen protector and case, wipe your iPhone down from any marks, and you can sell it for up to a third more.
Years ago a law was passed where any phone can be unlocked, making it free to use with any carrier providing 12 months has passed since purchase and both the phone and contract is paid off. We detailed which carriers are worth unlocking below:
Key Statistics:
- Don’t unlock: Verizon is the only carrier with consistent prices matching unlocked quotes.
- Consider unlocking: AT&T, T-Mobile and Sprint can earn you up to $105 more and can lose up to 24.5% of their resale value.
- Do unlock: Carriers other than Verizon, AT&T, T-Mobile & Sprint can earn you up to $200 more and can lose up to 51.9% of their resale value.
Solution: Purchasing an unlocked iPhone will not only earn you more when you trade-in, you will also benefit from lower monthly plan payments so the upfront cost evens out. Consider switching to a carrier like Verizon or AT&T, where you’ll know you can get the most money back down the line when you want to upgrade again.

Online VS Instore VS Carrier Trade-ins
Aside from negotiating a great private sale value for your iPhone, independent online trade-in stores offer the best prices – this is what we found comparing the top online trade-in price for an iPhone X 256GB against brand, in-store and carrier offers.

*Prices compared on 08/24/2019.
Online Trade-in VS Carrier VS Instore

- Apple: consumers would lose $130 (23%) of their iPhone X value selling directly to the brand’s trade-in service.
Hack #3: Protect Your Investment
iPhone’s With Scratches Can Lose Up To 34.9%
Typically, consumers buy cases to protect their iPhone from drops that cause smashed screens and damaged hardware. However, when you go to resell your iPhone the quotes you get from buyback stores will vary considerably by some cosmetic damage like scratches and little dents.

On average, an iPhone with cosmetic scratches loses 23% of its value
Trade-in stores don’t just offer prices for a working or broken iPhone. They provide a series of quotes for the condition of a working device. In general, this is how the pricing is tiered:
- Like new: Devices with zero signs of damage or wear
- Good: Devices that have light cosmetic wear, e.g. a few marks
- Poor: Devices that have scratches or dents on the case and screen
How does this scale impact price from a device that’s been protected and looks presentable compared to a phone with no case that’s gained scratches:
- Biggest money loss: Consumers can lose up to $100 on a scratched iPhone X or XS.
- Biggest percentage difference: Consumers can lose up to 34.9% of an iPhone 7’s value if it’s scratched.
- Typical cosmetic damage loss: Average iPhone owner could lose 23.0% of its value for having scratches, the difference in quotes range from 11.1% to 34.9% depending on the model.
- 2017-2018 Models: Consumers could lose 14.9% on average on an iPhone 8 or greater.

Solution: Before you get your new iPhone, buy a case and screen protector to put on straight away. Not only will it save you on repair costs, but it can also skyrocket your trade-in value later down the line.
Why? When you sell, pop off the screen protector and case, wipe your iPhone down from any marks, and you can sell it for up to a third more.
Hack #4: Carrier Unlocking
Your Network Carrier Could Cost You Up To 24.5%
When you buy a new iPhone, it will usually be part of a network carrier deal and locked to that carrier. Legally carriers can only keep you locked for 12 months, and if the contract term and phone payments are complete, you can unlock it and get paid a lot more – but this depends on what carrier you’re with:

Unlocking: Carrier unlocking an iPhone can earn consumers up to $200
Phones locked to a carrier, legally let you unlock them, Verizon is the only carrier that carries similar pricing to unlocked devices.
- Don’t unlock: Verizon is the only carrier with consistent prices matching unlocked quotes.
- Consider unlocking: AT&T, T-Mobile, and Sprint; they can earn you up to $105 more and can lose up to 24.5% of their value.
- Do unlock: Carriers other than Verizon, AT&T, T-Mobile & Sprint can earn you up to $200 more and can lose up to 51.9%.

Solution: Get your iPhone unlocked by its carrier to maximize your payout. BUT, not all carriers are worth unlocking, below we show examples of what you can earn on iPhones were released on 2017-2019.
Extra earnings unlocking the iPhone 8 and above:
- Verizon: 100% NO, you’ll earn up to $5 extra
- AT&T: You’ll earn up to $70 extra
- T-Mobile: You’ll earn up to $86 extra
- Sprint: You’ll earn up to $105 extra
- All others: 100% YES, you’ll earn up to $200 extra
Why? Legally you can get iPhones unlocked, keep in mind when you buy a new iPhone too.
How do I unlock my iPhone?
Thanks to the ‘Unlocking Consumer Choice and Wireless Competition Act’ carriers can’t keep you locked on their network for more than 12 months. The phone must be fully paid for, and the term of the contract you agreed must be up, e.g. 12, 18, or 24 months.
To unlock your phone, you need to call your network carrier with the information below to get it unlocked.
- Phone number of the main account holder
- Account password (if there is one)
- Last four digits of the account holder’s social security number
- IMEI number. This can be found by going to Settings > General > About or by dialing *#06#
Summary: How Bad Could It Get?
Visualize Factors Bleeding Your iPhone’s Value
What impacts your iPhone’s resale value (32 Stores)
Below we’ve created a chart showing the best deals from the 32 stores we compared prices on to explain how comparison, condition, and unlocking can impact pricing.
Important: The three criteria (condition, comparison, unlocking) individually subtract from the value of the phone. The depreciation is magnified when combined, for example:
If the iPhone XS Max is worth $810
- With cosmetic damage is worth $720 (-$90)
- No price comparison could be worth $670 (-$140)
- Locked to US Cellular is worth $610 (-$200)
So the iPhone XS Max should be worth $380, but in reality, having three of these negative factors will result in the consumers getting offered $195 – $615 less than its real value!
This is represented as the red column in the chart below:

- All three issues: As explained above the chart, all factors can deplete the trade-in value by up to 92.5% or $615 cash.
- Comparison: Consumers not comparing prices can lose up to 37.8% or $150 cash
- Cosmetic damage: Consumers selling with scratches can lose up to 34.9% or $100 cash
- Popular carrier: If your iPhone is locked to Verizon, AT&T, T-Mobile or Sprint you could lose up to 24.5% or $105 cash
- All other carriers: If you’re on US Cellular, Virgin, Metro PCS, Cricket or any other carrier you could lose up to 51.9% or $200 cash
iPhone Resale Price Exposure VS Broken Pricing
In the chart below we see how much you could lose out on online or in-store by not comparing prices, unlocking and protecting your iPhone:
- Green Column #1: shows the top iPhone price with all comparison, condition, and unlocking factors ticked off.
- Blue Column #2: shows the best price compared quote for the same iPhone with a shattered screen or functional problems.
- Red Column #3: shows how much a consumer could get low-balled on by choosing a bad quote, with an iPhone locked to an undesirable network with scratches.
In every case below, the quote was less than 50% of a cracked or non-functioning iPhone, unlocked, and where consumers compared prices.

Final Useful Tips
Other Pointers Worth Knowing
First impressions count! Give your iPhone a clean
The presentation of a clean tidy phone can make the difference when selling privately or to a company run trade-in store. If the phone looks new with no marks but is covered in grime, someone may offer you slightly less.
When selling your old iPhone privately, any buyer will be happy to pay more for a clean device, and they may even try to knock you down if it’s a mess. So, even if your phone has been in a case, you can take it off and wipe the device down with a cloth that is very slightly damp.
Do I keep the box and accessories?
It depends where you want to sell your old device, most trade-in services will not pay anything for the original box. The only use for this is you have a protective box to ship it in if you’re selling online.
In some occasions, we’ve seen the carriers requesting if the device has a charging cable, but the increase is so small it’s not worth it.
If you’re selling to someone privately, then having the box and accessories can increase the perceived value of the device. If you were buying a phone off a stranger, you would want the charging cable and the box it came in too. This means you’ll be able to set a higher price.
How to check if repairing a broken iPhone screen is worth it
There’s no black and white answer here, you’ll have to work out the math on your iPhone’s repair cost and the buyback value. You should check online prices for your iPhone screen to be replaced, most cost different Amounts so don’t choose a generic model, pick your own.
Once you know this, check out the price for your iPhone with a working screen and what you will get for a broken one. Then do the math as the examples shown below:
Not worth a repair:
- iPhone XS Max Trade-in Value: $810.
- Broken trade-on value: $450 (-$360 less than an unbroken price).
- Apple Screen Repair: $329 ($810 – $329 = $481)
- You’ll only make $31 more than the broken price ($481 – $450)
Worth a repair:
- iPhone XS Max Trade-in Value: $338
- Broken trade-on value: $185 (-$153 less than an unbroken price).
- AppleCare+ Screen Repair: $29 ($338 – $29 = $309)
- You’ll make $124 more getting it repaired ($309 – $185)
