What is the difference between Premium and Standard battery replacement?
In the Standard service, we just swap the battery, which triggers an 'Unknown Part' message in settings (for iPhone XS and newer). In Premium service, we transplant your original BMS (battery controller) to a new cell. This keeps the iPhone 'thinking' it's the original battery, showing 100% health and no errors.
Will I see the 'Important Battery Message' or 'Unknown Part' error?
Will the 'Maximum Capacity' in Battery Health show 100%?
Is the controller transplant process safe?
