Hi,
One of the most power consuming parts is the display so I changed the display to sleep after 30 seconds and have a low back light.
Additionally switch of the swipe to start feature of, because this feature needs the touch sensor switched on the whole time and so the z needs more power.
Additionally I had problems with leaks when I restore the settings. Because the old accounts have an other way to contact the server (LOT Bugfixes in this sector). This let to high battery usage for me.
And at the End this leak has been the first for me with an extremely long settle time! Other leaks worked from the start good battery timings.....
But this one needed more than one week to sette!
So at the end my Battery for 48 h with medium to heavy usage:
