I have been a big fan of Xperia Z series since the first Z. I changed my phone every time the new Z came out (except Z1 since I just started my career life without much savings).
Every time the new Z came out, I could find its awesomeness, imo, for example the first Z was stylish, waterproof, and powerful but it suffers a lot from heat,washed out display, and loosen waterproof charging caps. Then Z1 came out with more charming metal body, magnetic charging port, and 20 Mpixels camera, highest for a smartphone at the time.
Z2 came out as what the first Z should be at the first place with bigger and vivid screen, stereo speakers, and battery life is awesome to the point that I never found any others with this battery longevity at the time . For Z3, is almost identical to Z2 in term of spec sheet but I found it's very nice to hold in my hand plus the speaker is a lot better, far better than even Z5.
Z4 was very good on the spec sheet, especially with no more microusb cap but the battery life is a very big disappointment with almost half what Z3 lasts. It also suffers a lot of heat from normal uses. Z5 premium is, imo, the most refined Xperia with decent battery life, big screen, stylish material and colors selection.
Also, I don't know if it's me alone but every time I got the new Xperia on my hand, I felt really good and every single one of them was attractive.
Strangely, I can't explain but when I hold X/XP on on my hand, I didn't feel a thing, not even a glimpse of attractiveness although my country is offered 64GB/dual sims variant at the same price as Galaxy S7 (32GB/dual sims variant) with contract. I was never really into Samsung before (not because I hate it but I just neither found it attractive) but this time, I event think of waiting for Note7.
What are you guys' opinions? What are your before and after buying feelings toward X Performance?
