The basic idea of using the Acrobits intermediate SIP Proxy, is for their iPhone App not to be loaded into memory, unless there is an incoming call which obviously needs to be answered. If the registration from their intermediate SIP Proxy towards PBXes is not being maintained, then you should inquire with them, why the registration is lost.
Connecting to PBXes via TCP through any soft-phone, will reduce the amount of re-connections, but it will not eliminate them. Your battery will drain slower, but it will drain nonetheless. On Android based phones, using SipDroid via TCP or using CSIPsimple via TCP, will drain your battery at the same rate. It's a better option than using UDP, but it cannot be compared with using an intermediate SIP Proxy, to hold the registration for their iPhone based Apps, and use Push notification to load their Apps into memory to answer incoming calls.
This is definitely not how Sipdroid works with PBXes. There is no magic solution in this situation, without using an intermediate SIP Proxy. I don't like it since it introduces an element of security risk, but it's the only way I am aware of, to reduce the battery drain and use VoIP efficiently on an iPhone.
It requires a few disparate settings in various places of the Acrobits' Apps, but it seems to work properly on the iPhones I have configured it.
