Why is Siri draining so much battery on my iPhone 16 Pro Max ?

I am using a 16 Promax, iOS 18.4.1 (official version not beta).

A few days ago I realized that my Siri used too much battery like the below image:

And as some suggestions, I have turned off Siri and all off it’s functions since 9PM yesterday:

But when I check again today (18 hours from the time I turned off Siri), it is still on the top of battery draning app:

I believe this is a bug or something because an AI shouldn’t use so much battery even it was disable.

Please help me please!

Thank you for replying my post.

I am come from Vietnam, the same for region setting.

I tried a lot (turn off all Siri fuctions, disable Dictation, delete Siri&Dictation history) but they didn't help so I decided to reset my phone (erase all data and settings). This brings back my battery performance like before I enable Siri.

So if anyone has a problem with Siri like me on iOS 18.4.1, I'm afraid that the only solution is reset your device.

That seems unusual. What country are you in? What region is your iPhone set for? My settings for Apple Intelligence & Siri is different. Have you spoken with Apple Support?
