Does this only work on iPhone 15 and above? Or previous iPhones

[@howfixit]

Battery Calibration works for iPhone XR, iPhone XS, iPhone XS Max, and iPhone SE (2nd and 3rd generation), iPhone 11 models, iPhone 12 models and later

Oh ok but in my iPhone SE 2022 doesn’t show the Restart & finish repair but i changed the battery 1 year ago

[@howfixit]

What version of iOS is on your iPhone?

[@andrenunes6109]

latest one, 18.1.1 This only work with original battery ?

[@howfixit]

Most likely this will apply to the new battery

[@marik_hadare]

If I'm correct this only works when you buy battery from Apple as Self Repair Kit. It will no work with 3rd party batteries or second hand Apple OG batteries.

Does this mean we no longer need to weld on the original bms onto the new battery?

[@howfixit]

That's right, we don't have to deal with this s... anymore

Eg. If I got unknown part gonna locked, click cancel this? I brought second hand price.

[@howfixit]

Suppose you purchased a part that was removed from a locked iPhone. In that case, you will not be able to complete the calibration process successfully. The 'Unknown Part' error will remain until you unlock the part by entering the login and password of the Apple account to which the part is paired.

@@howfixitI have  id account but I brought replacement display and battery, they did stolen or new?

[@howfixit]

​@@nyinyitin9939 If you are unable to complete the calibration process, the parts were taken from stolen iPhones.

[@nyinyitin9939]
