question not directed at me though, but wanted to share
I got my Z3 compact 3 months a go
... can't be happier. I get 2 days of battery with 3 hrs of screen usage and 2 hours of phone calls, WiFi during the nights at home, LTE while outside (I never turn data off). Usage consists of browsing, facebook, 9gag, checking emails, whatsapp, etc...
As you see my phone usage is not much, so this phone fits my usage habits perfectly and it's small. Screen is not as bright as S-AMOLED, but does the job just fine.
This is definitely not a phone for gaming due to the small screen in my opinion, although it's perfectly capable per specs... I did miss watching videos in bigger screen (coming from a 5.5" note 2). But I would only watch videos and play games at home, for which I bought a 8.4" tablet, which is way better for that purpose.
BTW... Z5 compact kept almost same specs, and somehow they are getting less battery time... not worth it in my opinion for US$530 against US$380.
