Grandstream Wave Lite

response required

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.

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.

This app, while in the background, absorbs a huge amount of phone battery. It would seem that the point of it is mostly to be ready for incoming calls, etc. What good is it if there is no battery left to do all the work? If it’s power usage makes it so you don’t have it running in the background, how do you get your calls or messages? Makes it kind of useless, doesn’t it? There are many apps that do similar work but do not have this problem. How about a nice big update where the power drain is fixed?

Two major problems one is battery consumption is very high my phone dies before lunch With the app open and will make it through dinner time with the app closed. Also no push Also looses the connection and the dot turns red when I go from WiFi to cell data or the same going from cell data to WiFi it will loose the connection

Drains iPhone battery even when not in use in direct use. I checked my battery under settings after my battery was less than 20% in 5 hrs. The number 1 app listed was Grandstream Wave at 42% battery usage (background activity). The next highest was mail at 11%. Avoid this app if you want to use your iPhone for more than 6hr.
