Check the model number in your device settings, or bring it in and we will confirm the exact iPhone 16 Plus before any work begins. If you are unsure which repair you need, our team will advise.
Before you book
- If the phone has been opened before, we inspect the seals and connectors as part of the job.
- If the screen or back is already lifting, the cell may be swollen, so book promptly and avoid charging it.
- If the phone has had liquid exposure, a battery may not resolve everything and we check first.
