So, as you can see in the graph below, the Xperia Z2 has turned out to be among the best performers in the field, finishing right behind the Galaxy S5, which also has a fantastic result. It's always a good idea to keep in mind that battery life experience can greatly vary from user to user, due to different usage patterns and intensity, but all in all, it's hard to argue with numbers, and the Xperia Z2 has given us just that - indisputable proof that the battery it packs is a real marathoner!
Meanwhile, it seems the time it takes to charge the Xperia Z2 is fairly standard, which is to say that it's slower than some more forward-looking phones, like the GS5 and the Oppo Find 7a, which obviously employ techniques that allow them to fill up their tanks significantly faster.
