Specs: Iphone 14 pro: working with ios 16.3

Wifi disconnects if the phone is idle or locked for couple of minutes. It will work again if i turn it off and on again. It is strange that mobile data works well even if the phone idle or locked. It’s definitely not the issue with wifi router because my ipad, MacBook, and rest all works fine even while they are locked and unlocked. I don’t find any valuable information on this. Will be helpful if someone comes with a solution. All the reset options from network reset to complete phone reset was performed already.

That is an expected behavior. Only way to stay connected to wifi when the phone is idle or lock is to plug your phone into a power source. There is nothing wrong with your phone or wifi.

Maintaining an idle WiFi connection uses far more power than simply using cellular data for push notifications, etc. when the device is in standby. If the WiFi connection remained active while the device was idle, your battery wouldn’t even come close to lasting the day.

Don’t you think this might damage the life of the battery even though it has powerful lithium-ion batteries

No, it is impossible to overcharge the battery. The more that you keep the phone connected to the power adapter, the longer the battery will go.

I think this may be the bug issue with ios.

No, it's not.

Yes. That’s the way it’s worked since the very first iphone was released in 2007.
