People in Cheltenham are buying used iPhones more than ever. Makes sense. A brand new iPhone 16 Pro Max costs well over a thousand pounds. But a used iPhone 15 Pro or a used iPhone 14 Pro? You get almost the same experience for a lot less. The problem is not the phone. The problem is buying the wrong one from the wrong person.
I have personally seen buyers walk into our store with phones they bought privately that were iCloud locked, had cracked screens hidden under a case, or had batteries sitting at 67%. One customer came in with a used iPhone 13 Pro Max she bought off Facebook Marketplace in Cheltenham. Paid a decent amount for it. The seller had gone quiet. The phone was completely locked. That kind of story should not happen to anyone.
So this is a real checklist, not a generic one. Use it before you hand over a single penny.
Used iPhones for Sale in Cheltenham: What Buyers Are Actually Getting Wrong
The Cheltenham second-hand phone market is active. Scroll through any local selling group, and you will find used iPhones, used iPhone 14 Pro, cheap used iPhones, all sorts. Some are genuine. Some are not.
The biggest mistake buyers make is judging a phone by how it looks. A phone can look spotless and still have a battery at 74%, a replaced screen that washes out in sunlight, or an IMEI that comes back flagged. None of that shows up in photos. None of it shows up until you actually check.
Local stores are safer because they have a reputation to protect. A private seller on Facebook does not. That is just the reality of the market in Cheltenham and everywhere else in the UK.
How to Check a Used iPhone Before You Pay
Go through every single one of these. Not most of them. All of them.
Check the IMEI Number First, Not Last
Dial *#06# on the phone. The IMEI appears on screen. If the seller refuses to let you dial that, you are done. Leave.
Take that 15-digit number and check it on Apple’s official Check Coverage page or IMEI.info. Here is what you need confirmed:
| What to Check | What You Want to See |
| Blacklist / stolen status | Clean, not reported |
| Network lock | Unlocked, or locked to your carrier |
| Apple warranty | Active or expired, your choice |
| Activation lock | Off, cleared by the previous owner |

Sounds like a lot of steps. Takes about ninety seconds in practice.
Battery Health Tells You How the Phone Was Really Used
Go to Settings > Battery > Battery Health and Charging. That percentage is everything.
- Above 85%: You are fine, no issues expected soon
- 80% to 84%: Still usable, but battery replacement is coming
- Below 80%: Phones start shutting down randomly, and charging becomes unreliable

A used iPhone 12 at 78% is not necessarily a disaster. But knowing that number lets you make an informed decision rather than finding out the hard way at 2 pm when your battery dies.
Also worth noting: A high charge cycle count combined with low battery capacity means someone hammered that phone daily for years. Factor that in.

Used iPhone 13 Pro, 14 Pro Max, 15 Pro, and 16: Which One Actually Makes Sense to Buy?
This depends on what you need the phone for. Not everyone needs the latest model.
Used iPhone 15 Pro Max and Used iPhone 16 Pro Max: If You Want the Best
The used iPhone 15 Pro Max and the used iPhone 16 Pro Max are at the top of the second-hand market right now. Both have ProMotion displays, proper camera systems, and years of iOS updates still ahead. If you want something close to new but at a reduced price, these two are where to look.
The used iPhone 14 Pro and the used iPhone 13 Pro are solid alternatives. Still fully supported on iOS 18. Still excellent cameras. Still fast in daily use.
Here is an honest breakdown by model:
| Model | iOS 18 Support | Who It Suits |
| iPhone 11 used | Limited support | Very basic use only |
| iPhone 12 used | Supported | Budget option, decent performer |
| iPhone 13 used | Fully supported | Great everyday phone |
| iPhone 14 used | Fully supported | Better battery, good upgrade |
| iPhone 15 used | Fully supported | USB-C, strong cameras |
| iPhone 16 used | Fully supported | AI features, best longevity |

If you are going to buy the used iPhone 13 Pro Max or the used iPhone 14 Pro Max, expect a bigger, heavier phone with a fantastic screen and great camera output. Both hold up well even now.
Cheap Used iPhones vs Refurbished: Stop Treating These as the Same Thing
Used and refurbished mean very different things. Mixing them up leads to bad purchases.
A used iPhone is in whatever condition the previous owner left it in. No testing done. No worn parts replaced. No warranty unless the seller decides to offer one, which most private sellers do not.
A refurbished iPhone has been through a proper process. Battery tested, screen checked, all functions verified. Comes with a warranty. The seller stands behind it.
Why Buying a Used iPhone from a Cheltenham Store Changes Everything
Buying from a local store like Phone Max means someone has already done the work. The phone has been checked, graded, and is sold with accountability attached to it. If something goes wrong, you have a number to call and a physical place to walk into.
Private sellers cannot offer that. And honestly, most of them are not even hiding faults on purpose. They just genuinely do not know the battery health is low or that the screen was replaced by the person they bought it from. That is still your problem if you buy it.
Red Flags When Buying a Second-Hand iPhone: The List No One Talks About Enough
Some of these are obvious. Some are not.
- The seller does not know the Apple ID on the phone.
- Find My iPhone is still turned on. Check it yourself under Settings > Apple ID > Find My.
- IMEI comes back flagged or returns unusual results.
- The screen looks slightly cooler or warmer in colour than a standard model. This usually means third-party display replacement.
- The phone is warm on standby with nothing running.
- The SIM tray slot has a red or pink indicator inside instead of white. That means water damage at some point.
- Seller wants payment first and says you can test it “after.”
Any two of those together, and you should genuinely reconsider.

iCloud Lock: The One Thing That Kills a Used iPhone Deal Instantly
This is where a lot of Cheltenham buyers get burned. If the previous owner’s Apple ID is still linked to the device, that phone cannot be set up, reset, or used by anyone else. It is essentially worthless.
Before money changes hands, ask the seller to sign out of iCloud in front of you. Path is Settings > [Their Name] > Sign Out. They need to enter their Apple ID password to do it. If they say they forgot the password, or that they will “do it later,” or that it is already removed and you do not need to check, walk away.
That is not being difficult. That is being sensible. An unlocked phone with no iCloud issues takes thirty seconds to verify. Any seller who pushes back on that check is telling you something important.
Conclusion
The whole process outlined above takes about fifteen minutes. That is not a long time to spend before committing to a purchase worth anything from a couple of hundred to several hundred pounds.
Run the IMEI, check the battery, clear the iCloud account, and test every function. If you are in Cheltenham and want to skip the guesswork, have a look at what is in the Phone Max shop right now. Every device has been tested before it goes on sale. For anything else, screen repairs, battery replacements, and general servicing, the Phone Max services page has it covered. Buy from a place that can stand behind what it sells.
Frequently Asked Questions
How much is an iPhone 11 worth used in the UK?
It depends on the storage size, the condition, and whether it is network unlocked. A used iPhone 11 in good condition with battery health above 80% sits at the lower end of the second-hand Apple market. Higher storage options hold slightly more value. Poor cosmetic condition or battery health below 80% drops the value noticeably. Always compare a few listings before agreeing to anything.
Is buying a used iPhone from Facebook Marketplace in Cheltenham safe?
Sometimes, yes. Plenty of honest people sell perfectly good phones privately. But there is no warranty, no tested condition grade, and no protection if the phone breaks down a week later. If you do go down that route, insist on meeting in person, run every check in this guide before paying, and verify the IMEI before you hand anything over.
What is the best used iPhone to buy in 2026?
Right now, the used iPhone 14 Pro and the used iPhone 15 are the sweet spot. Both are fully supported on iOS 18, have excellent cameras, and will receive software updates for years. If budget is not a concern, a used iPhone 15 Pro or used iPhone 16 Pro is worth the extra spend for the better build and camera system.
How do I check if a used iPhone is unlocked?
Put a SIM from a different network into the phone and see if it connects without an error. You can also go to Settings > General > About and scroll to Carrier Lock. It should say “No SIM restrictions” if the phone is properly unlocked.
Is buying a used iPhone locally in Cheltenham better than ordering one online?
For most people, yes. You see the actual phone before paying. You test the screen, the buttons, the cameras, Face ID or Touch ID, everything. You clear the iCloud account in person. Online purchases skip all of that. And if something goes wrong with a private online purchase, recovering your money is genuinely difficult.
