iPhone 12 repair in Leeds
The iPhone 12 brought OLED to the base iPhone, and with it a dearer display than the 11's LCD. Apple publishes a repair manual for the 12, and none for the 11, and the 12 is the first generation whose Parts and Service History records the cameras and the logic board as well as the screen and the battery. The family is the 12 mini, the 12, the 12 Pro and the 12 Pro Max, and all four open from the front. Tell us what yours is doing and we will say plainly whether it is worth doing on a phone of this age.

The repairs
What we do on the iPhone 12, and what each job involves
-
Screen replacement
The iPhone 12 has a 6.1-inch OLED display, the 12 mini a 5.4-inch one and the 12 Pro Max a 6.7-inch one, and the OLED part costs more than the 11's LCD. Apple's display procedure for the 12 leaves the TrueDepth camera in the frame, so Face ID is not part of the display we change. We fit the display and test touch, brightness and the front camera before closing. A display that is not Apple's own shows as Unknown in Parts and Service History, and Apple lists what can go wrong with one, such as True Tone, brightness and missed touches; the quote says which part is going in.
-
Battery replacement
On the 12, Apple's manual takes the display and the speaker out first, then peels the battery's adhesive tabs, so a battery is a front-opening job. We fit a battery for your exact model and check that it charges, holds charge and reports its health. Settings, Battery, Battery Health & Charging shows the maximum capacity; Apple designs batteries of the 14 and earlier to keep 80 per cent of it at 500 full charge cycles, and a 12 of this age has often been through more than that.
-
Lightning charging port
The iPhone 12 charges over Lightning. A port that only charges at an angle, or not at all, is more often packed with pocket lint than worn: the plug compacts it into a hard layer at the bottom of the Lightning port. A careful clean is the first thing we try, for the price of the visit. A port that is worn is replaced from inside the phone, once we have ruled out the cable and the plug, which are cheaper and more often the cause. MagSafe is a second way to charge a 12 while a port is waiting for repair.
-
Water damage
Apple rates the iPhone 12 models IP68, to 6 metres for up to 30 minutes, and says the resistance can decrease with normal wear and that liquid damage is not covered by its warranty. If it has been in water: switch it off, leave it off, and do not charge it. Apple's own advice is not to put it in rice and not to dry it with heat or compressed air. We open it, see how far the liquid has gone, clean the board where we can, and give you the odds and a fixed price in writing before anything else. Nobody can promise a spill, and if it cannot be saved you pay nothing for the repair, only the £50 call-out if we came out.
-
Will not turn on, or stuck on the logo
A dead iPhone 12 is more often a flat or failed battery, a dirty port or a charger than a dead board, so we work through those in order and prove each before moving on. A phone stuck on the Apple logo, or looping, is usually software that a recovery restore clears, and we talk through what that means for the data on it before we start. Apple says unexpected shutdowns are more likely with an aged battery, a low charge or in the cold, so a 12 that dies outdoors with charge left usually has a tired battery, not a dead board.
Parts, honestly
Genuine, compatible, and what the software will say
Where a genuine part is available for your exact model we fit that; where only a compatible part is, the quote says so before you agree, and the price is different. Nothing is fitted without you knowing which kind of part it is. After a repair, the 12 records each replaced part in Settings, General, About, Parts and Service History: the battery, the display, the logic board and the front and rear cameras, where the 11 records only the battery and the display. A part Apple cannot verify is listed as Unknown, with a notification the first time you unlock the phone after the repair and again five days later. Apple's Repair Assistant, which calibrates a genuine part, is listed from the 12, and finishes a repair to the battery, the display and the front and rear cameras. The phone keeps working whichever part is fitted.
Is it worth repairing?
An honest answer for the iPhone 12
A battery, yes, nearly always: it is the single repair that makes a 12 feel new again. A screen is worth doing on a 12 that is otherwise sound, and Apple's iOS 27 runs on all four 12 models (Apple's compatibility list, checked 7 November 2026). A smashed back is where to pause: Apple's manual for the 12 has no back glass procedure, so it is a large job, and that is often the point at which the money is better put towards a newer phone. We say which before anything is ordered.
This is a phone repair job.
