I haven't noticed any battery drain. I love the real time widget. They have been building out LTE in my area now for a while, I am starting to pick it up in more places. I like having the chime come on when entering 4G. A couple cool options I wrote below, I'm not sure if they could be added.
1. When LTE drops, a down chimes plays so if you are not looking at your screen you know when the signal dumps. (still have the option to disable/enable it)
2. I use an aux cable (getting a new deck soon with BT) but would be nice if there was an option to disable alerts when either headphones/aux is plugged in or BT is streaming audio. It doesn't cut out my music, but it will play at the same time with the current version.
3. I actually like the chimes (I haven't heard the 800 alert yet) but being able to select system notifications or your own sound files would be cool or add more built in sound effects.
I really like the app & how it works so don't know if those things are even doable but I always like providing feedback. These aren't major issues by any means, would just be cool features.
Keep up the good work!
