Frequently Asked Questions
How can I tell if my iPhone 12 Pro battery needs replacing?
Go to Settings > Battery > Battery Health and Charging on your iPhone 12 Pro. If maximum capacity is below around 80 per cent, a replacement will make a noticeable difference to battery life. Common signs include the battery draining much faster than it used to, the device shutting off unexpectedly at 20 to 40 per cent, the percentage dropping suddenly mid-use, the device running warm during ordinary tasks, or the screen appearing to lift from the frame, which can indicate a swollen battery and should be booked in without delay.
Will I lose any data during a iPhone 12 Pro battery replacement?
No. Battery replacement is a hardware-only procedure. Your photos, contacts, apps and settings are not touched at any point. We do not access your software or factory reset the device during a standard battery repair.
What battery options are available for the iPhone 12 Pro?
We offer two options for the iPhone 12 Pro. The High Quality Battery is a quality aftermarket cell that restores normal battery life and performance, compatible with the iPhone 12 Pro's Lightning charging. MagSafe and Qi wireless charging are both verified after the repair. The Genuine Apple Battery is an original Apple component that clears any battery health or service warnings shown in Settings and matches Apple's original health monitoring. If you are unsure which suits your situation, we will advise when you arrive.
How long does a iPhone 12 Pro battery replacement take?
Most iPhone 12 Pro battery replacements are completed the same day, subject to parts availability and current workload. Walk-in customers are typically seen within a few hours. Mail-in customers from elsewhere in the UK receive their device back the next working day after the repair is complete. We contact you before proceeding if anything unexpected comes up during assessment.
Can I walk in without an appointment for a iPhone 12 Pro battery replacement?
Yes. Walk-in customers are welcome at our workshop near Liverpool Street Station during opening hours. You can also book online in advance if you need a specific time. For mail-in repairs, please place your order online so we can log and track your iPhone 12 Pro from the moment it arrives.
What warranty is included with the iPhone 12 Pro battery replacement?
Every iPhone 12 Pro battery replacement includes a 6-month warranty on the replacement battery. This covers manufacturing defect and failure under normal use. Physical damage and liquid ingress are not covered. If you experience any issue with the battery within the warranty period, bring the device back and we will assess it at no charge.
