Please, this topic is not about disconnection issues with different chargers or docking stations, or how many amps you can charge with, it is about a software issue where the phone recognizes a charger is plugged in, but does not switch to charging mode until rebooted.
You are experiencing a different issue. Please search for a topic on your specific issue, or open a separate topic for it if none exists yet.
This keeps the discussion, investigation, and discovered evidence focused and ultimately helps to get issues resolved quicker. Afterall it is easier to solve one very specific issue rather 10 vaguely related ones.
