ok. this will be like my first 12 hour usage experience with XZ. i will mostly be comparing with my old Z1
- first thing i notice is the screen. on the highest setting, it's brighter than Z1. on the lowest setting, it's dimmer than Z1 as well.
- the adaptive brightness seems to be too sensitive. it always adjust itself to the lowest setting when no direct light on it. causing the screen to be too dim. i end up switching it off.
- colour of the screen seems very punchy even after i switch off the x-reality. overall still looks better than my old Z1.
- speed... this beast is build for speed... everything seems very fast and smooth. all apps launched almost instantaneously.
- noticed some bloatware this time round like amazon, avg and zalora... cannot uninstall but fortunately can be easily disable.
- tap screen to wake doesn't seems to work all the time. double tap to sleep works flawlessly though.
- front facing stereo speaker! loving it! i used to cup my hand around the speaker whenever i am holding my Z1 watching video as the speaker is at the bottom. if not the sound will be like directed away from me and sounds very soft. now no more...
- Wifi... got to say it's very good. as soon as i switch it on, it'll straight away scan and connect to my house wifi in like 1 second... max 2 seconds.
- camera, miles ahead of my Z1. wasn't really expecting it to be that good actually. auto focus is fast generally, but not like 0.6s la...
- SA mode still seems to be grainy when zoom in closely. but then still much better than Z1
- the predictive focus seems to be working much better this time round than in the X. i managed to capture few shots of my 3yo moving around.
- i still prefer to use manual mode, with all settings in auto except the exposure level set to -0.3. the picture in this mode seems to be less grainy (same case as in my Z1)
- I still using 8MP as i think it's better than the full 23MP picture. but i still need more time to test this out.
- so for me right now, if i want to shoot moving object -> SA mode. for stationary object -> manual mode
- battery life is good thus far. as in my previous post, managed to get 5 hours SOT for today.

my old z1, even with stamina mode on and greenified downloaded apps, only manage to tops 4hours+
- stamina mode seems to be different on XZ as i cannot put any apps in standby list anymore.
so, overall as of now, can really feel it's a huge upgrade for me coming from Z1.
