Tomkay, guess what, my location based wifi works even with I turned OFF the Location. Glad to report it here.
Interesting. From my early tests, I seem to recall that it was necessary to have "Location" turned ON, but I could be wrong. I'm going to leave it ON for the time being because I'm not seeing any additional battery being used and it saves me turning it on manually whenever I use "Maps". The nice thing is that after I have used "Maps", GPS gets turned off automatically and consumes no more battery.
It took me a while to set up everything and I had to disable some services, but now I'm very happy with the battery life of my Z1 compact. From what I've seen the past days, my normal usage (some hours of screen time a day) and few, if any, calls, should get me through multiple days without a charge. I guess, I count as a "light" user.
May I also ask you about Double Tap to Wake? Do you think this feature eats up battery life?
My Z1 compact does not support double tap to wake. I can only speculate, but it seems impossible to me that activating such a feature will not take some (however small) toll on the battery life. A good phone maximised for battery life will completely turn off power supply to any sensor that is not in use and in order to support double tap to wake, certain sensing capability will have to remain active.
This is why -- after a short period of experimentation -- I switched off the ability to use "OK Google" from every screen. Having the latter active implies that the microphone is monitored from every screen and that should cost more battery life than only using the microphone when prompted to do so. I currently don't need a 100% hands-free operation, so I turned the feature off in the hope that it will gain me a bit more battery life.

I agree with you. Some sensors have to be on in order for the Double Tap to Wake to work. But my search on the internet shows that Sony does not have the battry drain issue for this feature, unlike Nokia (lots of reported cases).
I am going to try out by charging my phone to 100% before I go to sleep, and see what will the battery level is the next morning (try out with Double Tap to Wake On and Off).

Ok, I tested the Double-Tap-to-Wake (DTTW) battery usage over the last 2 days.
I had the DTTW switched on before I went to sleep at 1130pm, the batter was at 79%. When I woke up at 7.00am the next day, the battery was at 64%, a drop of 15% over 7.5 hours.
The next day, I had the DTTW stiched off. The battery at 11.30pm was at 72% level. The next morning 7.00am, the battery was at 55%, s drop of 17%.
I did use the phones during the middle of the night on both nights, just to check out the stock markets.
From this test, I did not see a significant battery usage by switching on the DTTW.
