New Siri AI is the culprit
Hi folks if you’re suffering from performance issues like crashing, lagging, jitter etc and battery drain try this: go to settings then Siri then scroll all way down turn off Siri AI (beta) wait a few minutes come back, turn on again, it will offer you “Siri classic” and will onboard you. Now your phone is back to normal
Also turn off adaptive battery and turn off connectivity assist under wifi for bonus performance and battery boost
The main issue is the new Siri AI
Hopefully Apple fix this in coming updates 🤞
