My drain is gone for more then 2-3 week already, and heavy use..None of the fixes seem to be permanent, after a few days google services is again the biggest power drain. Enabling Stamina Mode does seem to work, but has its bigger drawbacks.
Meanwhile I believe Play Services is not the underlying cause of the battery drain. Interestingly on the Xperia seems to have the battery drain issue, I haven't seen it reported as a major issue anywhere else. Could it be that one of the Sony-Apps is the root cause, likely invoking Play Services way too often? In that case we'll have to wait until they get their act together!
