Since iOS 14.6 update iPhone's battery drains while my smart battery case remains fully charged

I just updated my iPhone 7 to iOS 14.6 and since then the iPhone's battery drains while my smart battery case remains fully charged (ps. I did try all the steps stated in other articles).

Does anyone have a similar problem? if so do you have any solution?

Yes indeed. Had reported this issue at Apple Support. After iOS 14.6, the smart battery indicator no longer appears at lock screen the moment u plug in/unplug the charging cord, and the iPhone apparently draws power from the internal battery instead of the case. Remove/re-attach the case seems to be the temporary solution. The issue did not occur prior to iOS 14.6, i really believe it’s a iOS bug. Hope Apple Team could investigate & rectify it asap as it’s quite a serious issue.

It appears the update is treating different phones and different cases in different ways. As I said earlier my iPhone 11 promax and its Apple smart battery case is churching up just nicely. It doesn’t display as two separate batteries however. However it is charging up the battery case initially and the battery case is then in turn charging the battery.

how do I know this? To test both items i used the phone for 12 hours attached to the battery case. (Normally in previous IOS updates it indicated 3/4 of the charge is gone from the battery case but the phone is 100% charged. )

i removed the phone from the battery case and then plugged the phone directly. The phone displayed 100% charged. Therefore the case was charging the phone. I plugged in the case separately from the phone and it charged up fully in a couple of hours. Orange light-charging to green light - fully charged case.

next test. I used the phone for 12 hours with the phone/case combo plugged into the wall for the full 12 hours. Separated the 2, plugged the case in, and it showed green-fully charged, iPhone 11, fully charged.

conclusion. With this specific combo, iPhone 11/Apple smart battery case, it is functioning properly but does not display the smart battery case info at all. Hope the developers get their act together.
