Your phone is supposed to charge to 100% on occasion to let it calibrate the battery. It has always been that way with Charge Limits and nothing to do with iOS 18.6.2. Apple even documents that here:


If you have Charge Limit set to less than 100 percent, your iPhone will occasionally charge to 100 percent to maintain accurate battery state-of-charge estimates.
