What Hasn't Worked (lose battery %):
1. CM Default Music app playing (up to) 256kbs MP3s. Tasker task to do: WiFi on, Bluetooth on. Then I run Navigation app.
2. CM Default Music App. New Tasker Task to do: WiFi tethering on, Bluetooth on. I run navigation app.
3. CM Default Music App. New Tasker Task: WiFi off, BT on. I run nav app.
What Has Worked (battery successfully charges):
1. CM Default Music App. New Tasker Task: WiFi Off, BT on. No Nav app.
So the obvious difference is GPS. So my question to you is, are you running Nav and having the phone charge? Are your use cases the same as mine? If so, then I need to verify the amperage passing to the car audio cable. I appreciate any input you can give me on this issue. Thanks!
