Just to give an update, I was able to resolve issues for about a week. But the issues quickly came back, and I started to use Battery draining apps to watch apps. During the course of March, my Android Auto was not working at all with my vehicles wirelessly. There were 2 updates pushed to my phone. The first update did not resolve any issue. The 2nd firmware was received last week, and the had an issue with installing the update where it was finalizing the install - i think it was stuck on my external SD card (so I made a backup of it just in case). I deleted the partition cache in the recovery mode boot option. After clearing the cache, the update appears to have installed, and I no longer have any battery issues and Android Auto is working. Hope this helps, Android issues are frustrating - its great when it works, and its frustrating when it doesn't. I am not allowing as many notifications from every app anymore, and watching what apps are draining battery closely with Good Guardians. System Settings App, and Accubattery. I also limited the max charge to 85% in the settings. Last night, my battery drained 5% from midnight to 6 am. At the beginning of the month 100% battery drain occurred during the same time. Hope this helps some one.
