[Xperia Z General] XDA mark:
My first impression were very good: I posted them in many threads here.

Though I have some new info:

- Battery lasted for 11h42m yesterday, standby time. Screen on time: 3h22m (auto brightness). I have screenshots to back it up. I was always connected to wifi or mobile network. I didn't play games, mostly chatting, facebook, some youtube videos, listned to some music and internet browsing. It's not horrible, but not very good either. I got home with 1% left at 23:00 in the evening.

Today, I had worse results. Mostly at home all day, so wifi. Had a total of sub 3hours of screenon time! This is already my third charging cycle so I don't expect things to get any better. At the moment I am not impressed by the battery life of the XZ, but it's not horrible either.

- Phone's size and design: beautiful, though it's already not so "WOW" anymore (got used to it I guess). The phone atracts a lot of duts and fingerprints. But what I am starting to see is that the XZ is not so good looking at ergonomic aspects! It just doesn't feel nice in my hand because it isn't curved at the sides/back. I picked up my S3 again today and wow, it felt like a total different kind of thing. It was so comfortable in my hand compared to the XZ, while the S3 is almost as big as the XZ. And because the S3 has no onscreen buttons, the screen actually showed more info then the XZ.

- Screen: I'm getting more and more used to it, it looks really nice and sharp. Viewing angles are starting to bother me less and less, but sometimes I still see them.

- Speaker quality: seems very loud, but quality wise it seems bad. And I cover it up with my right hand a lot without wanting too.

I'm thinking about returning the XZ.... yeah. Didn't expect it myself. But the main problem is: it doesn't feel like a big leap from my S3. So basicly, I bought a new phone (the XZ) which feels much worse in my hand (ergnomic wise, it's not comfortable) then my S3, the screen is bigger but I actually see less content on it because of the software buttons, and while the screen is sharper a bit the viewing angles and contrast are worse. It also isn't a lot faster then my S3, it doens't do anything my S3 couldn't till now (yes HDR video, I tried it once and that's it).

My biggest problem is the size and design: without the curved sides/back the phone is hard to use for me with one hand. Really didn't expect this. This together with what I said above, make me consider returning the XZ and wait for a few more months. I saw (again) an article on a big Ducht newssite about the XZ's succesor and that it will come in summer 2013. It should have a 1080p 4.8 screen and the S600 chipset. This off course also doens't really help my feeling of returning the XZ...

I still have till next week to think about my XZ, but I might return it. No offence to Sony, the XZ is really a good phone, but the fact that I can't use it comfortable in my hand is something important to me. I do have small hands, but I can use the S3 perfectly and the XZ not so much.

EDIT: The other problem is, there isn't anything at the moment which I would consider buying. I have looked again at the HTC One and still don't want it. Maybe I will return my XZ and wait for Samsung to reveal the S4 and hope that it's build quality/design is a step up from the S3. If not, I can get the XZ (or the succesor of the XZ) beginning of the summer. Really bummed out..
