Wi-Fi keeps dropping on iPhone 13 despite full signal strength

Have a iphone 13, of late the wifi keeps dropping off although the signal bars show full strength wifi, all other devices at home have no problems . Phone has lots if spare storage, no VPN on that could interfere either.

Talktalk have reset the router remotely,phone is updated , have done iphone reset as well.

Am not too tech savvy but any advice appreciated.

Is it dropping when using the phone, or when the phone is locked?


IF it is only when the phone’s screen is locked, that is by design to save battery energy. Wi-Fi will shut off 30 seconds after the screen locks unless the phone is connected to power.


If Wi-Fi drops when you are using the phone, that clearly shouldn’t happen. Things to check:



  • Open Settings
    • Tap General
    • Tap Transfer or Reset Phone
    • Tap  Reset
    • Tap Reset Network Settings


    • This will erase all Wi-Fi passwords, but will not result in any other data loss.

Thanks Lawrence, tried all the reset /update options, it happens when iphone unlocked.

Connection had been fine for years.


To get wifi back i have to turn wifi off/on and its ok then for a few hours, never effects my ipad though.

Find it odd the wifi signal bars show strong strength even when the phones wifi disconnects!

Talktalk have done router tests and i assume resets their end ,and they say no issues found .
