App Doesn’t Run in Background Properly

When I’m connected to a Grandstream UCM, and my phone network changes (from WiFi to cellular or vice versa), sometimes the app automatically reconnects. Many times it does not. My phone has been connected to my company’s WiFi, connected, and when I walk outside, I get disconnected and reconnected notifications like it’s supposed to. The app, however, never seems to reconnect when I get home, and as a result, gets stuck in a disconnected state and I have to reconnect the following morning when I realize I’m not getting any calls because my phone hasn’t reconnected automatically.

Contacted GS support regarding this, and they told me to check the Background App Refresh setting (already on). Beyond that, they stated they tested on their end, and found no issue, pointing me to a StackOverflow article discussing how iOS apps behave in the background.

So Power Hungry

I used to love this app when I first got it. Now I feel like a recent update has made this just about unusable. It used 68% of my battery in the last 24 hours and I probably only actually used it 3 times yesterday. Most of that time was the background refresh. It should not take THAT much battery to remain connected in the background.

Developers: if you can’t fix the battery drain, at least provide us with the ability to set hours that it will refresh in the background and crush our battery. I shouldn’t lose 60% battery overnight and wake up with a dead phone just because my phone’s not plugged in.
