You could've used the connectors on the side of the tablet to connect the Qi receiver to avoid overcharging situations. Because it it a Li-Polymer battery and it may explode with overcharging.If you have a bit of electronic experience, I tied a Qi receiver into the battery leads in my device. Now I can wireless charge it at about 1.6 amps. Downside is device does not know it's charging. Upside is it charges very fast and no more worries about software and hardware issues charging wise.
