Normal Operations are as follows
Upon connecting the XT90 's the charger will go full blast, stage A
In the last 5-15 minutes it will slow down and the sound reduce a hair, stage B
Then the final stage C it really slows down and the sound really reduces but you can still hear it.
All the sounds are constant and consistent at each stage.
Symptoms are as follows
1st full blast stage is fine.
If I move the charger it will still go fine.
If I leave it, and listen it seems that when its in its near or in the second stage it will sometimes go very low then back to normal with no movement of the charger. If it stays low, I move charger and it goes back to normal.
