This is weird. I have a brand new Moto X, have had it just a week and installed the KitKat 4.4 OS a couple days ago. Battery life has been very good until suddenly today I noticed the Motorola Assist was eating up a huge amount of battery. The phone was sitting idle most of the day, a few texts and a couple alarms set, nothing else. Location, WiFi and Bluetooth all turned off, there was nothing else that should have been high battery usage. The battery monitor said Motorola assist was using 40% of the battery. I had all the settings checked in Motorola Assist but there was nothing going on for it to monitor, it was daytime, no meetings and I wasn't driving. I turned everything off but the sleep rule, and recharged the phone. Just a few hours later, phone sitting idle, and battery down to 48%. I checked and now it said Motorola Assist was using 70% of the battery! I did a Force Stop and disabled it although it says this may cause the phone to misbehave....
