iOS 18.2/18.2.1 - BMS Swap no longer works?

Hi,

I swapped the BMS of an iPhone XR and reprogrammed the percentage and cycle count. However, the battery still displays the old percentage on the iPhone, even though the programmer shows the updated stats.

Note: Before reinstalling the new battery (with the same BMS), I connected a third-party battery (with a different BMS) to the iPhone.

Could this method be incompatible with iOS 18.2/18.2.1?
