This actually is one of the worst as it almost permanently calls home at any time. Look at this log of my firewall:
It keeps on calling home nearly every minute. And usually it is blocked. Just imagine how it would go beserk if not being blocked spending data volume, using and keeping active any available data connection draining your battery.
Once in a while I unblock it if going to the store. Then it keeps on transmitting whatever data until I leave again and block it.
Although it does not look like it is a resource hungry monster. I can only give you advice to also get a firewall to have more control over such apps. This will have an overall positive effect. Or switch over to another OS.
