What model iPhone do I have?

Is the battery included high quality?

All of TechXS' high quality iPhone batteries undergo individual testing to meet our high quality control standards. All batteries have the same capacity (mAh) as the original part, and are IE 62133 certified per Australian requirements.

Will I void my manufacturer’s warranty by doing the repair myself?

In Australia, if a product is faulty, customers are legally entitled to a repair or replacement under Australian Consumer Law, and sometimes even a refund. This warranty supplied with a product is not void if a third party, including you personally, repairs the device. The Australian Competition and Consumer Commission (ACCC) made this stance clear in the case of Apple’s misleading representations to its customers.

Why choose TechXS’ Home Repair Kit solution?

This is not your average drop-shipped product that leaves you picking up the pieces. From part quality, to access to technical support, our solution allows peace of mind all in the one small box.
