Disabling it will still allow all your devices to work in find my like they have traditionally, through the internet. You’ll be losing the feature to find your devices if they’re turned off or not connected to the internet, however.
Thank you very much for this tip! I disabled it and now the battery life kinda doubled on 13 Pro Max. Before it was like 60-65% in the evening, yesterday it was 80% (2h screen time on average). At the same time FindMy usage was around 10-15%. And that is with zero AirTags paired.
But I just don't get it. My wife has a 12 Pro. Two Airtags paired, zero problems, FindMy is between 1% and 2% battery usage.
