We’ve noticed brief connection drops only after an iPhone has been locked and asleep for a while—almost as if the Wi-Fi radio powers down and the access point simply queues traffic until the device wakes. When the phone is unlocked, the connection remains solid. Our use-case requires the link to stay alive continuously, even during extended sleep. Are there any iOS settings (or other device-level options) that can keep Wi-Fi awake under all circumstances? Beyond Wi-Fi configuration itself, are there iPhone- or iOS-specific factors that might influence connection stability while the device is locked? We don’t see the same behaviour on Android handsets connected to the exact same network.

Observing this too. Unclear what's happening.
