Ive experienced battery drain dramatically with this app along with music not displaying the right song name, connectivity is perfect havent experience a bad connection, the BLE utility app is a little more battery friendly and is working perfect with the others issues,I can go a full 8 hour shift at work connect it with the BLE UTILITY app and still be at 48% at the end and with AERLINK app (on the iPhone ) it drains it 3-4 hours into my day.... Yet I love where the app (AERLINK for iPhone ) is going and will continue to support and pay for development, hopefully one day we will be able to use the Moto 360 fully with the iPhone thru AERLINK app
