iPhone Repairs | Screens, Batteries, Liquid Damage, Startup and Charging Problems
From iPhone 12 to the latest models, Mobile Repair Pro Shop handles cracked screens, ageing batteries, liquid damage, startup and charging failures, Face ID and system issues. Free inspection and a clear explanation of the cause and quote come before your approval—no work first and consent later. Most screen and battery replacements are ready for same-day collection in 20–30 minutes, with full testing and written warranties on major repairs.
Common iPhone fault symptoms
- Cracked display, touch failure or abnormal images
- Rapid battery drop, unexpected shutdowns or device heat
- Will not turn on or malfunctions after liquid exposure
- Slow charging, poor contact or no response
- Will not turn on; unresponsive black screen
- Face ID unavailable
- Stuck on the Apple logo or unable to update
- Speaker, microphone or camera problems
Quick answer: iPhone repairs fall into five main categories: display problems (Screen replacement), ageing batteries (Battery replacement), Liquid damage or short circuits, Charging port, as well as System software problems. Repair versus replacement mainly depends on the extent of damage: if only one part is faulty and the logic board works, repair usually costs much less than a new phone. Severe board corrosion or several failed core parts deserve a careful comparison. We are at Shop G81B, G/F, Sin Tat Plaza, Mong Kok (MTR Exit D2), open daily 11:00–20:00. Free inspection and quote approval come first; most screen and battery replacements take 20–30 minutes.

In-Depth Guide
iPhone repair guide: diagnosing faults, model differences and repair versus replacement
Last updated: October 2026
iPhone 12 to iPhone 18 Pro and iPhone Duo: what differs between generations when repairing?
iPhone generations differ in internal construction, charging ports and parts availability. Identifying the exact model before repair matters:
| Model | Points to note for repair |
|---|---|
| iPhone 12 and 13 series | Lightning port; as these models have been available longer, parts supply is relatively established |
| iPhone 14, 14 Plus | Redesigned internal structure allows rear-glass removal, making some repairs easier than before; the 14 Pro series retains the earlier structure |
| From the iPhone 15 series onwards | Moves to USB-C, so charging diagnosis differs from Lightning models; the battery is designed to retain around 80% capacity after 1000 cycles |
| iPhone 16, 16e | Apple's official repair manual describes electrically releasing the battery adhesive for removal, which requires the appropriate tools and procedure |
| iPhone 17 series | USB-C port; parts availability depends on the model |
| iPhone 18 Pro, 18 Pro Max | Launched in Hong Kong on 18 September 2026. As this is a recent model, please check parts availability first |
| iPhone Duo (foldable) | Launched in Hong Kong on 23 October 2026, the first foldable iPhone has a specialised inner display and hinge. Inspection and confirmation of parts availability are required before repair |
*We repair the iPhone 12 series through to the latest models. Parts for newer models depend on availability; please enquire via WhatsApp first.
Whatever the generation, the process is the same: inspection, quote and approval before work. Apple recommends running Repair Assistant on supported models after battery replacement. For details, see iPhone Battery Replacement.
iPhone will not turn on: what can I try myself?
For an iPhone that will not start or has a black screen, Apple recommends a force restart: on Face ID models, quickly press and release Volume Up, then Volume Down, then hold the side button until the Apple logo appears, possibly more than 10 seconds. If still unresponsive, charge for one hour and retry. Continued failure may involve the battery, port, board or system. If it has been wet, do not charge it; seek repair directly. Avoid opening it yourself and worsening the damage.
How do I decide between repair and replacement?
The two main factors are the extent of damage and the device's age. If only one or a few parts are affected, such as a cracked screen, ageing battery or loose charging port, while the logic board and other core functions work, repair usually costs a small fraction of a new phone. If liquid has severely corroded the board, or the board, screen and battery all fail, combined repair costs may approach replacement cost, so compare carefully. Data matters too: with many unbacked-up photos and work files, repair may be more practical than replacement. Whatever you choose, a free inspection and an actual quote are better than deciding on guesswork.
Will screen replacement affect Face ID and True Tone?
Face ID uses the TrueDepth camera above the display; its sensors are separate from the screen glass. A professional screen replacement that handles the sensors and flex cables carefully normally leaves Face ID unaffected. True Tone depends on the display type: Apple states that it may not work correctly on non-genuine displays, and Parts and Service History will show “Unknown”, although normal iPhone use is unaffected. For details, see iPhone screen replacement.
Official repairs or an independent phone specialist: which suits you?
Apple's Hong Kong website states that its limited warranty covers manufacturing issues for one year from purchase, excluding accidental damage and normal battery wear. AppleCare plans provide service for accidental drops and liquid spills and free battery replacement below 80% capacity. Apple's repairs and replacement parts are covered for 90 days or the remaining warranty, whichever is longer. Check official service first for AppleCare+ or covered manufacturing issues.
Out-of-warranty devices without AppleCare+ require paid repairs. As an example, Apple's Hong Kong website estimates HK$999 for an out-of-warranty iPhone 18 Pro battery repair and HK$3,249 for screen damage (October 2026 figures; check Apple's latest prices). Independent shops such as Mobile Repair Pro Shop offer same-day collection and clear prices, and accept out-of-warranty devices, parallel imports, used phones and previously opened devices.
| Criteria | Apple or authorised repair service | Our shop (independent phone repair specialist) |
|---|---|---|
| Best suited to | AppleCare+ or a manufacturing issue under warranty | Out of warranty, accidental damage or urgent same-day collection |
| Turnaround | Depends on official arrangements | Most screen and battery replacements take 20–30 minutes |
| How quotes are provided | Official pricing | Free inspection; work starts after quote approval |
| Out of warranty / parallel import / previously opened | Handled according to official policy | Accepted — diagnosed then quoted |
| Warranty | 90 days or the remaining warranty period, whichever is longer | 1–3 months' written warranty on major repairs (subject to the warranty document) |
*Official terms are subject to Apple's latest information. Our terms are stated in the in-person quotation and written warranty. We are not an Apple Authorised Service Provider.
Before repair, know: Apple states that iPhone 11 and later, excluding iPhone SE (2nd and 3rd generation), have Parts and Service History under Settings → General → About, showing repairs to major parts such as the battery and display. Non-genuine parts show “Unknown”, which may affect trade-in value but not normal use. We explain the part type before repair so you can decide.
Choosing quality repair parts: why cheaper is not always better
Parts quality varies across the industry. Poorly screened parts may cause colour differences or unresponsive touch; poor batteries can swell or overheat. Choose a shop with permanent premises, written warranties, free inspection and quote approval, and clear explanations of part types. See Parts quality explained and Official service and our shop compared.
What should I prepare before an iPhone repair?
- Back up your data: Most hardware repairs do not involve erasing data, but back up with iCloud or a computer first as a precaution.
- Make sure you know your passcode: Your screen passcode and Apple Account password may be needed for collection tests or system troubleshooting.
- Remove the case and screen protector: Lets the technician inspect the body and screen edges.
- Explain what happened: When it started, any drops or liquid exposure, and any previous repairs.
- For official service: Apple's guidance states that Find My must be turned off in iOS 26 or earlier; in iOS 27 or later, “Prepare for Repair or Trade In” can be enabled in the Find My app.

FAQ
iPhone repair FAQs
Most iPhone screen and battery replacements take 20–30 minutes after the free inspection, while you wait. Charging port and software repairs usually take 30 minutes to 1 hour; liquid-damage recovery takes 1 hour to several days; logic board repairs depend on the damage.
We repair the iPhone 12 series through to the latest models. Apple launched iPhone 18 Pro and iPhone 18 Pro Max in September 2026 and its first foldable iPhone Duo in October. New-model parts depend on availability; older models can also be discussed. WhatsApp your model first to check stock.
Apple recommends trying a force restart first. On Face ID models, press Volume Up once, press Volume Down once, then hold the side button until the Apple logo appears. If it still will not turn on, charge it for one hour and try again. If that does not help, the battery, charging port, logic board or system may be at fault. Bring it in for a free inspection rather than opening it yourself.
Face ID is generally unaffected by professional handling, but associated sensors and flex cables require care. True Tone depends on the display type: Apple states that it may not work correctly with non-genuine displays. We explain the display type before repair and test it before collection. See iPhone screen replacement.
Apple states that iPhone 14 and earlier batteries are designed to retain around 80% of original capacity after 500 complete cycles, versus 1000 for iPhone 15 models. Consider replacement below 80% maximum capacity, with unexpected shutdowns or noticeably shorter runtime. See iPhone Battery Replacement.
Screen, battery and charging port repairs normally do not erase data. Logic board repair, liquid-damage recovery or system restoration may affect it. The technician explains the risks beforehand and recommends a backup. See Data backup and recovery.
If damage is limited to one part, such as the display, battery or charging port, and the logic board works, repair usually costs far less than a new phone. Severe board corrosion or several failed core parts may make repair cost close to replacement. Start with a free inspection and compare the quote.
Check official service first. Apple's Hong Kong website states that AppleCare plans provide accidental drop and liquid-spill service and free battery replacement below 80% capacity. Without AppleCare, after warranty expiry or for urgent same-day collection, consider our shop. We are not an Apple Authorised Service Provider.
Yes. We provide free inspection and quote based on actual condition for expired warranties, parallel imports, used phones and devices opened elsewhere. An expired warranty is not a reason for rejection.
Major repairs include a 1–3 month written warranty; the exact period is stated in the warranty document. If a component itself fails during the warranty period, excluding damage caused by the user, bring the document back for a free recheck or follow-up.
