my iphone 13 oro max will not stay connected to my att uverse, what us the problem
Iphone 13 Pro Max will not stay connected to my Att uverse WiFi, why would that be happening?
iPhone 13 Pro Max, iOS 17
When does it happen? All iPhones from the beginning of iPhone time 17 years ago disconnect from Wi-Fi 30 seconds after the phone screen locks, to preserve battery energy, unless the phone is connected to power. This is done because a Wi-Fi connection uses power continuously, whether data are transferring or not. Cellular connections use more energy, but only when actually sending data. There are a few exceptions:
- If you are streaming audio or video Wi-Fi will stay on
- If you receive a notification Wi-Fi will reconnect for a few seconds to process the notification
- And, I think (but I’m not sure) if an app uses Background App Refresh it can wake and use Wi-Fi; however very few apps actually use Background App Refresh.
If it happens while the phone is unlocked that’s a different problem:
Do you use VPN? If so, delete the VPN profile in Settings/General/VPN & Device Management/VPN. Don't just turn it off; delete the profile.
Does it happen with only one network, or all Wi-Fi networks? If only one, try restarting the router
