Yes these are GTA01Bv4. 
When the device enumerates the current draw goes to 490 ma which is fine. 

There are other charge anomolies. For example, on initial charge (battery in
cutoff and inserted) the charge current (initial 40ma) will drop after several
hours to zero but the bat will not in fact be charged. It will be charged enough
to get the device to enumerate, but it will then need several hours at 490ma for
the battery to reach a full charge. 

Additionally, it appears the battery is float charging which is not good. The
battery should be allowed to drift down to 3.9V or less and then get a top off
charge to bring it back. This is probably just software that can be refined as
the PM matures.
