    iPhone 7 disconnects from wifi after not being used for few hours. Then it doesn’t see any wifi network albeit there is my home one. So I need to restart it what is pretty annoying. Any clue what to do to make it notice wifi?

      Have you tried the methods in this article?
      Or maybe you need to reset your iPhone (this may erase all the content on your iPhone).

        Yes, I did, but it is annoying tbh. When I reset network settings I need to provide again all passwords to all wifi – at home, work etc. Cannot it be fixed by Apple, I am sure it should be iOS update to solve this issue.

    I do not think that in every place, in different countries where I use my iphone6, everywhere the router is badly configured, moreover my iphone 4S works all right without disconnection. So I tried the methods with the phone. No change, my iphone6 is disconnecting from wi-fi all the time when it is locked.

      Hi Tibor,
      Well, it seems normal for many iPhones that they disconnect from Wi-Fi when locked. They do so to save battery. You can try plugging your device to power and see if it disconnects when you lock it.

        If I want to save battery, I can turn out the phone. But having a smartphone with me, I want to be able to RECEIVE calls by internet means… viber, facebook, skype etc. It is crazy to have an expensive iPhone 6 with me, sitting near to a very strong wifi, and my smartphone is not more useful than having a brick in my hands. No difference it is connected to power or not. At home I connect the phone to power AND turn locking out. It is the only way not to disconnect. When going out of home, I have to take with me my old iPhone 4S. It is working perfectly, the screen locks but I receive all calls, messages etc. sent from the internet. The two phone’s settings are identical, and I tried everything what I have found in the internet to solve the problem. And, concerning the battery saving… in the iPhone 4S I have the very old, first battery… and it is enough for 40-50 hours… more, than the iPhone 6 battery with this “battery saving”…

          Hi Tibor,
          I am sorry to hear that and I sincerely understand that this is a frustrating issue.
          Here is a method you can try: Go to your Cellular settings and turn off WLAN Assist (it is in somewhere near the bottom).
          Hope this can fix your problem.
