[Huawei P9 Questions & Answers] Akinaro:
I was user of Sony and Sony Ericsson almost from start. From ""recent"" Sony devices I had Xperia Z, Z3 and compact version, and last year for some time I used XZ and Galaxy S7 when I wanted to buy new phone... and I choosed P9 instead, and probably like you, I jump to P10 (or even plus version) after it show up.

1. Build Quality, Huawei is on pair with Xperias, and in some ways, especially fitting of elements, its even better than some Xperias, that after year just... move or dont fit like before. I also drop my P9 few times and I have only one 2mm scratch on side after it hit rock in park... it was miracle that it dropped like that because normally phones fall on screen...

2. Materials? I would call it draw again, they are very good quality, especially screen that is really though, after all those years I realized that even if two phones use some fancy gorilla screen name... they are different in terms of quality and how they manage scratches.

3. Camera? Sony have best sensors, but worst algorithms you can imagine. Last good Sony camera in phone I saw in Xperia Arc S, after that they just get one really bad drivers and copy/paste it to every phone. Huawei in other hand, especially in P9, beat a crap of Xperias, even the new one. Its fast, it have nice algorithms that dont mess quality, it have LOTS of options, and you get almost perfect details and colors if you know how to handle it.

4. Screen. I could say that XZ have really nice screen, P9 is also nice, but... it just lack some "punch" in terms of brightness and colors. Not much but, I can say that galaxy S7 blown my mind in terms of quality of screen, but even that was not enough to buy it. In every day usage P9 dont give any troubles, even on direct sun, so I could say that compared to XZ its overall draw again...

5. Performance.... Xperias are really simple and give you that "almost stock" experience, but even XZ, just like Z3 have that slow down without a reason and it can actually lag in simple task like using browser. In more demanding task it can work really good, but P9 even with slower GPU is not behind it at all! I was actually surprised that it P9 work so fluid and even VR games dont give it much troubles. Also P9 in everyday usage is really amazing, no hangs at all. That was one of key point why i choose it, because even S7 had that slow downs when doing simple task not related to games or other heavy tasks. From addons like Fingerprint sensor(that is damn fast) rest is perfect, no problems at all... Also speed of camera on Xperias are really average, camera app is just sluggish, and the same with starting phone. Xperia XZ needed x2 time more to boot up than P9

6. Software. Here is a bit tricky choose, because Xperia UI is simple and nice, and Sony have nice update policy, and it have really good customization community, but its a bit slow sometimes without a reason and after I switched to EMUI... i found out that Xperias where really... outdated and stripped from most of options. Even if Huawei update system is... just slow and weird, EMUI have loots of customization options, simple way to theme it without any complications, build in applications are really nice and easy to use and overall it give that perfect experience of good phone system. You can hear that some people have problems with EMIU 5 after update... but Its nothing new, when I had xperias, it was the same, ALWAYS about 25% of people whine about "bad" update. EMUI 5.0 is just perfect if you update it properly. Simple as that.

7. Battery life... Here Sony literally F up xperias. As far as older Xperias like Z3 and its compact version had amazing battery life, when I used XZ... it was just... average, After day and a half I had 15-20% And for past good 5 years, I literally use the same apps over and over so it give me some nice look of how battery life work in every day usage on all phones.

And here come P9 that, true, after update to EMIU 5.0 its a bit worst compared to 4.1.1, but its difference of less than 10% I still can get with my P9 solid two days of usage and I still have about 20% left without turning off any features like NFC or Bluetooth.

I just have small tip to make it even better: in App setting section, just turn off internet access to all apps that dont need it, and use optimization option every day. Huawei P9 is just in top10 if you looking for device with good battery optimization. And I think they will do the same with P10.

Also worth mention is charging. I found out that xperias always charge slower and it almost stop charging if you use phone in the same time. my p9 with stock charger can get almost full in... hour or two AND STILL charge so fast if I use it in that time!

So yeah, as a user of Sony, and now Hauwei device, I can say that Huawei is what Sony was few years ago.

Because Sony now give us average devices that maybe are nice made, but are overpriced and with every generation some key features are "worst" or the same as previous ones.

Huawei in other hand give us nice made devices, with nice price tag, some amazing features(like camera in P9) and what I wanted most: stable and good experience in everyday usage, even if their update policy is a bit average... But most of people whine that they need new udpate that beside adding new number in phone info... work the same, so im not mad if I need to wait that month or two more to get that new number...

Overall that why I choosed P9 instead of XZ and galaxy S7(that actually was just 10Euro cheaper(promotion), but even if screen was AMAZING... it was just... not what I expected from it). P9 is stable and reliable and have few features that I need in phone, and P9 give me what I need.
