Blynk Connectivity in Australia and battery use

[mattocastillo]

Hi!
I have a LilyGO SIM7000G here in Australia, and it's working quite well, actually. The only issue is that on the Blynk platform, I notice it has frequent reconnections. Sometimes it can go 6 hours without reconnecting, and other times it reconnects every minute...

So, I have two questions:
-To save battery and use Blynk efficiently, is there a way to do this effectively?
-Regarding the reconnections, is it normal for it to be like this, or is it possibly trying to connect to an incorrect band? It's connected to LTE in Australia, but I have almost all bands enabled for the country and haven't selected any particular one.
Thanks!
