Major battery problems since since updating my V10 to Marshmallow, the battery is now being severely drained by the app com.lge.exchange. This never occurred under the previous version of Android. I've tried resetting the phone to factory defaults and re-configuring my outlook.com mail account to no avail. Tried using several different apps for email, no difference. Any app that uses activesync sucks the battery down in less than 8 hours. The only option I've found is to use IMAP to connect to outlook.com, but this means only having to wait on polling intervals to receive emails instead of having them pushed immediately to the cellular, not a good option!
Anyone else seeing this behavior?
