Thanks. Some of those Google services even could be turned off, the others I already had limited like you suggested.
I will have the phone automatically activate for ten minutes in the morning before shutting down again, in this time my WLAN also turns on, and any updates of apps and stuff could be automatically run then. After that time, both things switch off again. I have no need to have the phone running when I am at home. I can manually activate it again when I think I need it.
Data volume prediction tells me I will have consumed less than 80MB mobile data by the end of the the 30 days-interval.
No, Google really will not love me, I think. Thats what I love, however.
