"Find My" 100% background activity battery usage.

This problem started to happen as soon as I got my iPhone 14 running iOS 16.6 out of box, where at night hours battery usage would show 100% for Find My running in the background even after turning off the service which should not cause the draining issue. Tried reseting the phone to factory settings, still problem not solved. Been trying to contact apple support specialists for them to have a closer look, but unfortunately it seems like I cannot to do so in my country/region. Please if you have encountered a similar issue, share your opinions and help me to solve mine. Thanks.
