iOS 27’s Connectivity Assist is designed to maintain connectivity when Wi‑Fi is weak, drops out or is unavailable.
Reports say it may keep the cellular radio active even on a stable Wi‑Fi connection.
A Reddit user reported increased screen time after disabling it, but that anecdote does not establish a general effect.
The setting is under Settings > Wi‑Fi and must be disabled separately for each saved network, according to the
A Reddit user reported that after disabling the feature on his iPhone 15 Pro Max, screen-on time increased from 3–4 to 7 hours. Battery health was 89%. Another user, with an iPhone 16 Pro, described heating and rapid battery drain until he found the same setting. These are user reports, not proof that Connectivity Assist causes the same problem on all iPhones.
Where to find the setting on iPhone
Open Settings > Wi-Fi . Connectivity Assist needs to be turned off both from the general option and separately for each saved network. For example, check your home and work Wi-Fi: if the feature remains active on one network, it still works there.
Check Adaptive Connectivity on Pixel
There's a similar report about Adaptive Connectivity, the connectivity feature in Android. A MakeUseOf writer found that, despite having disabled it in the Pixel 7's settings, it was still showing up in the background services. This happened after a system update, when the phone's battery life dropped sharply.
To check the services, first enable Developer Options : in Settings > About phone , tap Build number seven times until you see the confirmation message. Then, go to Settings > System > Developer Options > Running services . The list shows which services are using memory and processing power in the background. If Adaptive Connectivity is listed there, you can disable it from that screen.
