Interesting write up on the best way to charge Li-Po batteries. Scroll down to "What the user can do" if you want to skip the science bit. Basically running till empty is the WRONG thing to do according to this study..

Another interesting thing mentioned is how charging rate affects battery health. The faster the charge the more stress on the battery. Could the slow charge rate of the Z2 be Sony cleverly trying to lengthen our battery health? Maybe!
