Battery drain by HOME ACCESSORIES that does not exist

Hello,

After updating to IOS 15.1 both my iphones (11 and SE 1st generation) get a battery drain when idle.

When i check the battery usage i see that most consumption is due to HOME ACCESSORIES. Especially on iPhone SE which is always idle in a drawer, it seems that Home Accessories is responsible for 100% of the battery usage.

This is completely new and strange to me as i do not have any home or other accessory connected to my iPhones (not even headphones).

To make things even more weird i see this battery usage when i check the 24hours statistics, but when i go hour by hour there is no reference to HOME ACCESSORIES activity.

Do you have any idea on whats going on? It is rather frightening something that does not really exist to take over and use your phone.

Do note that HOME app was never opened and actually i have deleted it on both my phones since IOS 14.

Thank you in advance for your help.
