[Q] not Charging from external Battery (USB)
My Atrix does not have any Problems with charging when connected to my PC, but it just wont detect the external Battery i own.
It shows no reaction, when the Battery is plugged in via USB and then turned on.
When the phone is off and the battery is connected and turned on, the phone will boot, but still not charge.
I was trying to find out why the Phone won't accept the Battery so I measured the outgoing Voltage: 6,3 V
Note: 2 out of 2 other phones (1 running Android) detected the battery and charged from it without any issues.
The external Battery was really expensive since it comes with a large solar panel to charge it, so I really ought to get this to work!
Does anyone have any Idea what I can do to force my phone into USB-charging mode? Or how to make it detect the battery?
