Available repairs

Screen Replacement for iPhone 12

The iPhone 12 uses a 6.1-inch Super Retina XDR OLED display with Ceramic Shield. A cracked or unresponsive screen requires a quality OLED assembly replacement to restore colour accuracy and True Tone support. Face ID is stored in the TrueDepth camera module and is not affected by a screen replacement. Repair takes approximately 30-45 minutes while you wait.

Battery Replacement for iPhone 12

The iPhone 12 battery is rated at 2,815 mAh. Reduced capacity over time causes shorter battery life, unexpected shutdowns, and iOS performance throttling. A genuine-grade replacement battery restores full-day battery life and removes the throttle. Replacement takes approximately 30 minutes. Walk in any time or book an appointment.

Charging Port Repair for iPhone 12

The iPhone 12 uses a Lightning connector. A faulty charging port — caused by lint buildup, corrosion, or physical damage — prevents charging and may cause intermittent sync issues. In many cases a thorough cleaning resolves the problem at no charge. If the port needs replacing our technician can complete the repair in approximately 45-60 minutes.

Back Glass Replacement for iPhone 12

The iPhone 12 has a glass back bonded to a flat aluminium frame. The rear glass is removed using specialised heating equipment. Back glass replacement takes approximately 60-90 minutes. Book an appointment so we can match the exact colour of your device.

Speaker Repair for iPhone 12

The iPhone 12 features both an earpiece speaker and a bottom loudspeaker. Muffled audio, crackling, or complete silence — especially after a drop or liquid exposure — typically indicates speaker failure. Both the earpiece and loudspeaker are straightforward repairs completed in approximately 30-45 minutes. Walk in or book an appointment.

Logic Board Repair for iPhone 12

The iPhone 12 logic board houses the A14 Bionic chip, Face ID controller, wireless chipsets, and all core circuitry. Common issues include liquid damage, no-power faults, boot loops, and baseband failures. We perform component-level repair on iPhone 12 logic boards with an 80% success rate on liquid-damaged units. No fix, no pay — always.
