Why does charging cradle charge so slowly?

[Soony]

My cradle charges the tablet very slowly, even when I have no apps open and screen off.  And why does the charging cradle sometimes just stop charging even though tablet is not fully charged, even when tablet is powered off over night?  Thanks for any info

Yes, I am upgraded to 4.2.2, but cannot say whether that correlates to the charging problems.

My cradle doesn't charge at all when smart connect is on!!! when it's off it charges with no issue. Strange. Called sony support and they never heard...had same issue with 4.1 and 4.22
