    • Chips used in batteries of iPhone XS and above feature an authentication module which stores information that can be used to pair the battery cell with the phone’s logic board.

    • To remove the Important Battery Message, we can transplant the battery management system of the original battery to the replacement battery.

Thanks for sharing! What device can be used for welding the parts? I don’t want to damage the cells of the battery in this proces?

Also will the new battery will be displayed as 100% in the settings menu?

You need a welding machine as shown in the video to finish the job. And you will get the same battery health as before.

No need for a welding machine according to this youtube vid (see around 2 mins in). Just a cheap soldering iron can be used.

Now you gave ideas to apple to make the BMS module like the one from laptops: once you disconnected the cell it will require re-programming (which is not possible because of a security key) :)

Instead of welding, would silver conductive glue work to attach the BMS to the new battery?
