Testimonials

  • iPhone 13 Mini

    Great battery, definitely recommend it. Replaced on iphone 13 mini, it got detected as genuine used part, health is 100%. In the box you get battery, battery adhesive, and a little leaflet.

  • iPhone 13 Mini

    10/10 install was a breeze! Iphone recognised as genuine part ! Apple wanted £85 to replace i did it myself for under £30!

  • iPhone 14 Pro

    Quite easy to replace, in the settings it appears as a genuine used battery and it stayed at 100%.

  • iPhone 15 Pro

    Excellent, the battery shows "Genuine Part." The installation was normal, there are no difficult steps to configure. It appears with a maximum capacity of 100%. Let's see how it performs over time.

  • iPhone 12 Pro Max

    Got the battery did everything within 1 hour. Had to clean out all the glue. That was the hardest and longest part. Installed the battery tested it. At 1st will have the warning. But after updated in the repair section the warning is gone and genuine part is recognised. But must have a very stable connection then you can update. All good now will update after charging fully and full use for tomorrow

  • iPhone 13 Pro

    At first I had doubts, but when I used it, I was surprised. I totally recommend it, and the battery lasts too long.

iOS compatibility

Diagnostic batteries are tested and confirmed to work with the current iOS version at the time of sale (iOS 26.5.2). Apple may change system behaviour in future updates. Compatibility with future iOS versions cannot be guaranteed and is not covered under warranty.

Diagnostic IC behaviour

The diagnostic function relies on a reclaimed IC (IC7037). Each IC is data checked prior to use, however it is not possible to identify every faulty unit. In rare cases, incorrect battery data may be displayed. This is a known limitation within the repair industry.

Manufacture date display

On iPhone 15 models and iPhone SE (2022), the battery manufacture date shown in system diagnostics may appear incorrect or unusually long. This does not reflect the actual production date and cannot currently be avoided.

This product is not manufactured or endorsed by Apple Inc. It is designed to restore genuine battery data using third party or refurbished components tested to OEM standards. The diagnostic function is guaranteed to work only with the system version available at the time of sale (iOS 26.5.2). Compatibility with future system updates is not covered under the warranty.
