Google Play Service 9.2.56 drains battery within 30minutes
My "solution" is freezing Google Play Services 9.2.56 with the disadvantage that some Apps relying on that service will not work anymore.
Restore to the previous 9.0.28 version does not solve the problem, because it will automatic be updated to 9.2.56.
I tried to find a way to contact the Android developer team at Google, no success.
