HTC Battery Life – possible trick

I'll need to confirm this but I've just found on the web (via an anonymous post) that you can almost "double"..... battery life.....

 

I highly doubt this, but it's worth a punt.

1. Turn your device ON and Charge the device for 8 hours or more
   
2. Unplug the device and Turn the phone OFF and charge for 1 hour
   
3. Unplug the device Turn ON wait 2 minutes and Turn OFF and charge for another hour
   

Seems like allot of "faffing" so I'll need to confirm this.
