Storage is the biggest swing on an iPhone 12
The standard iPhone 12 and the 12 mini were sold with a 64GB base tier, now the weakest thing in the range. Storage that small is awkward for a modern phone, resale buyers avoid it, and the gap between 64GB and 128GB is wider than most sellers expect.
The 12 Pro and 12 Pro Max started at 128GB and topped out at 512GB. They hold value better for that reason alone, before you count the telephoto lens and the LiDAR scanner.
Check yours on the Capacity line in Settings, General, About, and quote us that rather than what you think you bought.

Batteries and Face ID: the two faults we expect
This generation is old enough that original batteries are usually well below 80% and often showing the Service Recommended message. We price that in as standard rather than treating it as a defect.
Face ID is the fault worth checking yourself. On aged units the module can fail outright and the phone reports Face ID as unavailable. It is a real deduction, because putting it right is not a light repair and cannot be done with a generic part.
Test it in daylight and again in a dark room. A module that works in one and not the other is on its way out, and saying so up front keeps the WhatsApp figure and the counter figure identical.

Why an iPhone 12 still has buyers in the UAE
It was Apple's first 5G iPhone and the first with MagSafe, it has the flat-edge design people still like, and it runs a supported version of iOS. That keeps it moving as a second phone, a work phone, or a first iPhone for someone stepping up from much older hardware.
That demand is why we pay a real price for one instead of treating it as scrap, and why condition counts for more here than on a newer model. A clean screen, an intact Ceramic Shield front and a straight frame are what separate a good offer from a poor one.
04
The No Service board fault, and the MagSafe check
There is a known population of iPhone 12 and 12 Pro units that lost mobile service completely because of a logic-board fault, not the antenna and not the SIM. Apple ran a repair programme covering affected units. It is the most expensive fault an iPhone 12 can have short of liquid damage, because the fix is board-level.
Test it before you message. Put a SIM you know works into the phone, let it register, then read the Network line in Settings, General, About. Dropping to No Service in a basement or a lift is normal; sitting on No Service with a good SIM everywhere you go is the fault. If yours was repaired under the programme, say so — that counts in your favour.
We also check that the MagSafe ring still grips a charger. A weak magnet is often the first sign the back has been opened, which tells us more than the magnet itself does.
