FAQs
Will I lose my data?
No. A battery replacement does not normally affect your data. If your phone powers on, you can keep using it as normal afterwards.
How long does it take?
Many iPhone 11 battery replacements can be completed the same day, subject to stock and workload. Mail-in repairs are turned around quickly once received.
What warranty do I get?
All battery replacements come with a 6-month warranty.
Will battery health show after replacement?
Our batteries are fully compatible and in many cases battery health will display on the latest firmware. If iOS shows an “Important Battery Message”, we will explain what that means for your device.
Can you fit an original battery?
Yes, where possible. Please contact us for a quote and lead time.
What if the phone still drains fast after the battery change?
If we find another cause (for example, a charging fault or board-level issue), we will tell you before any additional work is carried out.
