Why does charging cradle charge so slowly?

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

if you turn off your wifi/data plan it will charge faster, also if you receive an email the notification LED will start flashing but the tablet will continue to charge.

Re: Why does charging cradle charge so slowly?

Thanks for your comment.  What do you mean by "turn off your wifi/data plan"?  I am going to try setting the tablet on Stamina Mode in the Power Management tab.  Is that what you have in mind?  But why would any wifi setting interfere with complete charging if the tablet is powered off in its cradle?  Doesn't "off" mean "off"?  Regards, S

if the wifi is on then some apps might upload/download data. this will slow down the charging process

Re: Why does charging cradle charge so slowly?

Yes Fourire1 is describing one of the same problems that I had. Tablet on cradle overnight and powered off yet next morning not fully charged. Additionally, on other mornings I find that the tablet miraculously had turned itself back on (and as far as I can figure out the Smart Connect is not programmed to turn on the tablet, but who knows since there is no comprehensive user guide).

Does it take the same amount of time if you use the regular wall charger?

Do you us the right cable? I also have a sony Xperia Z and that cable is not the same as for Tablet Z. Charger is the same. Dont know IF it has to do with usb 2.0 and 3.0.

Re: Why does charging cradle charge so slowly?

I use the original cable and converter supplied with the Xperia tablet z.  

 

I charge overnight in the cradle with the above described cable and converter.  After docking, I power off the tablet prior to charging, which presumably means no apps or wifi are running during charging. 

 

The big questions are why in the morning (1) sometimes it only charged to about 85% after eight hours and (2) sometimes the tablet apparently turned itself back on overnight.  

 

(Someone may reply to turn off a wake-up setting in Smart Connect, but as far as I can tell there is no such setting activated now or in the past.)

Re: Why does charging cradle charge so slowly?

Have you upgraded to 4.4.2?  It may be just a coincidence, but I started having same charging issues with Sony supplied power and cable when I upgraded.  I could turn unit off and leave overnight.  The charge would not get above 90%.  Because I purchased Sony warrenty, I went to Sony store and explained the problem.

 

They had not heard of this issue "yet" on the upgrade.  So I asked for exchange.  They thought it might be battery issue.  They exhanged unit that still had 4.1 on it.  I ignored the upgrade notice icon and charging is now back to normal on this new unit. Fully 100% charge in a few hours.  So, was it a bad battery......of a strange fluke for 4,2?   

 

At this point, I am skittish about doing the upgrade until someone at Sony can confirm that some units with the upgrade exhibit this fluke.  Again, it may be a very bizarre coincidence.
