Summary
Reddit reports tied iOS 27 battery drain to Connectivity Assist, with one iPhone 15 Pro Max user saying runtime fell to 3-4 hours before rebounding to 7 hours after disabling it.
Connectivity Assist now appears to use Wi-Fi and cellular together when a wireless signal weakens, a change from iOS 26's Wi-Fi Assist, which simply switched to cellular.
The feature also sends DNS requests over cellular data, potentially bypassing ad blockers; Apple itself recommends turning it off for users who rely on ad blocking.
Users in the same thread said disabling the setting also eased overheating, and iOS 27 lets owners switch it off either per network or globally in Wi-Fi settings.
