Maps are huge battery killers unfortunately, if you also keep location on all the time it is even worse.
I have experienced this several times when using maps continuously (google maps).
I have Z1,not Z,but I think lollipop will have the same outcome. You can also search around the forum for other ideas or wait to get other.
I think it is better in terms of camera,processor,RAM,battery backup. But Z was the first of this awesome generation.
Nice choice, have you looked at Z3 compact?
