  1. iPhone 6s+ wifi disconnect while locked

I recently bought iPhone 6s+ and running iOS 9.2.1. Whenever I lock (sleep) my iPhone, the wifi automatically disconnects, and once I unlock or press the power button, it automatically connects. I don’t think it’s any quiet feature bcoz I have delayed notifications thanks to this from apps like Whatsapp, Gmail, etc.

Is it normal behavior from iPhone?

Android has a ‘keep wifi during sleep’ option. I am missing that badly 🙁

Please help anyone.

P.S. battery saver mode is off..background app refreshing is on for all apps. I even tried reset all settings and network settings..what should I do?

  1. wifi turns off when iPhone goes into sleep mode/is locked

As the title says, my wifi keeps disconnecting whenever my phone goes into sleep mode. This started happening the instant I signed with a replacement internet provider and that they came to visit line up the new gear. I even have read online that turning off wifi in sleep mode may be a feature that’s alleged to preserve battery which the iPhone is meant to be doing that, but I used a variety of various wifi’s since getting the phone (my old one from another provider, my friends’, public, etc.) and wifi would ALWAYS stay albeit my phone is in sleep mode and locked for whatever time.

I suspect the matter is with my new router and my phone (all other phones – Android, Windows, work FINE on my new router and that they never disconnect, the wifi works flawlessly with them). So it’s just my iPhone that is the problem. 

  1. Hidden wifi disconnected automatically

I have hidden wifi at home and ready to configure and use it. After a few minutes, like the laptop goes on sleep or locked after a few minutes, I see that the wifi is disconnected. Once I open the setting option, then it’ll connect again.

  1. iPhone Xs Max LTE/wifi disconnect issue

My iPhone Xs Max (256GB variant) is facing few connectivity issues:

Suddenly (4-5 times a day) it loses internet connection via wifi, it shows wifi signals on my phone but no internet. My other devices connected to an equivalent network works fine during that point. My iPhone shows this internet blackout for like 2-3 mins and starts working back as normal.

Whenever my phone switches from wifi to LTE (when I leave home or work), it takes 8-10 mins to attach to the LTE network; the phone shows LTE/4G network immediately but doesn’t hook up the internet. So I had to attend for 8-10 mins to attach or toggle Airplane mode on/off to urge it to connect manually.

Apart from these two issues, I’m also facing the opposite common problem: others reported where my iPhone doesn’t charge once I connect the charging cable and the phone is in sleep mode.

Pls, help. I attempted contacting Apple Technical Support in the Netherlands, but it looks like they’re not conscious of all this; they even denied that others face similar issues, whereas I see apple-related forums crammed with an equivalent.
