Thanks for the suggestion, but unfortunately it's not that. If that were the problem, then why would it resume charging normally after a simple reboot?paulcornwall wrote:The problem is the cable. It will only allow 300-500mA to pass through. Change it to a better cable and you will see the current draw increase to 1.1 -1.2A.
Besides, I (like most others experiencing this, I expect) have already tried with a whole bunch of other chargers & cables.
The issue is that it slowly loses charge if plugged in while it is currently turned on & in use.
It is presumably trickle charging (like you hint at, perhaps @ 500mA) due to some issue in the hardware/firmware/whatever, until the device completes a full shutdown or reboot cycle for whatever reason. This isn't enough to sustain the battery level, but it does drain slower than if it weren't plugged in at all.
Regardless, I've long since given up hope of an easy fix, and just reboot whenever I need to plug in / charge.
