Exchange service polls every minute and drains the battery Two days ago my Sony Xperia J phone's battery began to be drained very quickly. It seems, the Exchange service has gone mad (it uses 57% of the battery time). It polls constantly, I get a new mail every minute according to it (I have only 1 new mail actually). I already restarted the phone.
It even polls when it requests a security update.

What have gone wrong? Did Google release a new version of it?
I switched to a 3rd party Exchange app and set the built-in Email application to Manual sync. It seems to work now.
