Ok a long one here...
Using the Mojo mainly as a desktop DAC, have been using it a few hours every day for the last 4 days, in use, the charger is plugged in constantly, when I finish the session (usually late at night because this thing sounds amazing) battery is full.
Now, because the explanation given by Rob
here, I found the behavior of my Mojo a bit puzzling.
Next day I pick it up to use it, (always less than 20 hours since the last session) connect it to the charger and it seems battery is NOT full and starts charging, usually takes 15 - 20 min before charging light goes off (fully charged).
While in operation the charging light is always blue

I should mention the first two days I was using an HTC charger of 1amp, the last few days using an 2.1amp charger, same behavior.
Bit concerned since is stated clearly on Mojo's manual that charging it while off is recommended. I would like to avoid charge and play at the same time.
Anyone with a similar experience?
Update: while playing, charging light went from blue to white, which to my understanding means is charging the battery.
I don't know what to take from this, does this mean the Mojo was using the battery and using more power than what the charger can provide?
