- Where is the difference of “at home” and “at office” in your case? Different charger?
- I mean the connector at the phone itself (as you can see at the pic in the other thread). But basically it could also happen to the plug of the charger itself.
- did you already try the “Battery-Software Reset/Recalibration”? But that would only make sense, if you considered the possibility fo the “dusty connector”, which then should be cleaned before!
