Since about a month ago, my phone is dropping connection every 15min when it's closed. This can be in the middle of a call even (timed it today and it happened exactly 15min into the call and then again 30min (15min later) into the same call. If I leave my phone on the desk and don't touch it, I get no notification of people write to me on WhatsApp for example and when I press the power button and unlock the phone I can have some 10+ messages popping up.

Any ideas? :(


  • For the notifications, ensure you have the apps enabled on start-up in the Battery menu.

    Can you tell us what you see on the screen when you disconnect on 30 minutes of a call? Is this just a normal phone call or is it using something like WhatsApp or Messenger, Google Talk, etc?

    Battery options is in check, never changed it either.

    I don't know if it happens on phone calls as well, I rarely use that for calls nowdays.

    What do you mean with what I see? If the phone is left locked for over 15min, I get no notifications, when I unlock the phone after say an hour, I can receive over 10 messages as if the internet connection isn't on until then (which is what happens).

  • What I meant is there anything that is showing the Internet is timing out for you?

    By the sounds of the issue, it does sound like your apps are sleeping/hibernating. You said battery never changed, but what the phone does is learn to when to hibernate or put the apps to sleep.

    I would try two things:

    Suggestion 1:

    Settings - Battery - PowerMaster - Auto-start manager - ensure apps that you want notifications to be enabled;

    Settings -Battery Optimization - Under All drop down box, ensure you have apps that you want notifications, are not optimized.

    Once these settings are done, restart your phone.

    Suggestion 2:

    You can try doing this if you think the Internet is timing out and not the apps sleeping/hibernating.

    Settings - Sysytem - Reset Options - Reset WIFI, mobile & bluetooth.

    The first thing was already set as it should. I tried to reset and restart but it's still there. Didn't have an opportunity to try until last night.

  • Can you try to see if you get disconnected at 15 minutes within Safe Mode please? Hopefully it will give us an indication on what the problem is.

    How would I test it with safe mode on? WhatsApp is disabled so I suppose I need so measure using something else?
