Five quick steps before you post your iPhone 12 Pro Max. Each one protects your data and lets us turn around your payment faster.
iCloud or Finder backup keeps your photos, contacts and messages safe so you can restore them on your next phone.
Go to Settings → [your name] → Sign Out. Then Settings → [your name] → Find My → Find My iPhone, and switch it off. We can't process your trade-in until Activation Lock is removed.
We don't need the SIM, charger or accessories - keep them for your next device. Your trade-in price is for the iPhone 12 Pro Max alone.
Settings → General → Transfer or Reset iPhone → Erase All Content and Settings. This wipes your data so the next owner starts fresh.
We email you a free Royal Mail QR code - show it at any Post Office and they print the tracked label. Or book a free Royal Mail collection from your door and we'll handle the rest.
Use this guide to grade your iPhone 12 Pro Max accurately. Honest grading means you get the price we quote with no last-minute deductions.

Powers on, fully functional, no cracks or chips, screen and back glass free of scratches, casing in near-perfect condition. Not engraved or personalised - the original or close-to-original look.

Powers on and fully functional, with everyday wear: light scratches on the screen or casing, minor scuffs or marks. Engraving or personalisation is fine at this grade. No cracks or screen damage.

Anything else: cracked screen or back, water damage, or a faulty battery. It must still switch on. We still pay a fair price - select Faulty above.
Released: November 2020.
Apple launched the iPhone 12 Pro Max in November 2020. It was the flagship of its generation and the only iPhone 12 with the larger main camera sensor, which is why it is still bought as a working camera phone rather than a cheap spare.
Envirofone has been turning old Apple devices into cash since 2005, with over £160 million paid out and more than 44,000 Trustpilot reviews. Getting a price for your iPhone 12 Pro Max takes about 30 seconds: pick your storage size and condition above, and the quote you see is the amount we pay. We email a free Royal Mail QR code you can use at any Post Office, or book a free collection from your door, and payment lands the same day your iPhone 12 Pro Max arrives and passes our test.
The iPhone 12 Pro Max holds more value than the standard iPhone 12 of the same age, and the gap is wider than most people expect. It was the flagship of its generation: stainless steel frame, 6.7 inch display, a physically larger main camera sensor than any other iPhone 12, a 2.5x telephoto lens and a LiDAR scanner. Buyers still seek it out for the camera specifically.
Apple gave this model a sensor the rest of the range did not get, and sensor size is one of the few camera advantages that does not become obsolete with a software update. That is why the 12 Pro Max is still bought as a working camera phone rather than as a cheap spare, and why its trade-in value has held up better than the generation around it.
The stainless steel and glass build is worth a moment before you sell. It is a heavy phone with large flat surfaces, so it tends to show edge scuffs and corner marks even when the screen is clean. Grade on the worst part of the device rather than the best, and the quote you get will be the quote we pay.
Apple Trade In pays in store credit against a new Apple purchase, so the value only exists if your next device is also an Apple one. We pay cash into your bank account, with no obligation to buy anything, and we take iPhone 12 Pro Maxs in conditions Apple declines outright, including cracked screens, failed batteries and water damage. If you are buying a new iPhone anyway the two are worth comparing on the day; if you simply want the money, or your iPhone 12 Pro Max is faulty, cash is usually the better outcome.
A cracked screen, a swollen or dead battery, a failed camera or water damage does not make your iPhone 12 Pro Max worthless. Damaged devices still carry a real cash offer, because the parts that survive go back into refurbishing other handsets. Choose the Faulty condition when you get your quote rather than hoping the damage goes unnoticed: we test every device on arrival, and an accurate description means the price we quote is the price we pay.
One thing to do first, whatever the condition: sign out of iCloud and turn off Find My. A device still locked to an Apple ID cannot be processed, and that is the single most common reason a payment gets held up.
Every iPhone 12 Pro Max that gets refurbished and resold instead of going to landfill saves tens of kilograms of CO₂-equivalent emissions and keeps valuable rare-earth metals in circulation. Smartphones contain gold, silver, copper, lithium and cobalt - materials with a real environmental cost to mine fresh.
Envirofone has been part of the UK's circular-electronics movement since 2005. Every device we buy is tested, refurbished and given a second life with a new owner - or, if it's beyond repair, recycled responsibly so the materials don't end up in a landfill.
Your Apple iPhone 12 Pro Max trade-in value depends on its storage capacity and condition. In excellent condition, you could receive up to £220. Devices in fair or faulty condition receive a lower but still competitive offer. Get an instant, no-obligation quote above - it only takes a few seconds.
In the UK, the Apple iPhone 12 Pro Max is currently worth up to £220 in Excellent condition through Envirofone. Higher storage tiers attract a premium of around £20–£40 over the base model. Prices typically drop £25–£35 a month after a new generation launches, so locking in your quote with our 14-day price guarantee is the best way to maximise your payout.
Apple's own Trade In programme only gives you store credit toward a new Apple device - no cash. Envirofone pays you directly by bank transfer the same day your Apple iPhone 12 Pro Max passes our test. We also accept faulty and broken devices that Apple Trade In often won't, so if you want maximum flexibility and real money in your account, Envirofone is the simpler route.
Trading in with Envirofone is faster, safer and free. Private sales on marketplaces can get you a slightly higher price, but you handle the listing, the buyer questions, the meet-up or the postage, and the risk of payment fraud. With Envirofone you get a guaranteed price, free Royal Mail postage, no listing fees, and same-day payment with zero scam risk.
Yes. Envirofone buys faulty Apple iPhone 12 Pro Max devices - whether yours has a cracked screen, water damage or a faulty battery. Select "Faulty" as the condition above and we'll give you a fair price. It does need to switch on: we cannot accept a device that will not power up, or one reported lost or stolen.

Before sending your Apple iPhone 12 Pro Max, back up your data, sign out of your account (Apple ID for iPhones), disable Find My Device, and perform a factory reset.

Once it passes inspection, payment is processed the same day via bank transfer - or choose EnviroCash for a 7% bonus to spend on a refurbished device. Most customers receive their money within 3–5 days of accepting their quote, including postage time.
Trade-in values for the iPhone 12 Pro Max drop by roughly £25–£35 each month, with steeper drops around major launch events when newer models arrive. Selling sooner rather than later locks in the highest value. Our 14-day price guarantee on every quote protects you from drops while your device is in the post.
