[Device Reviews and Information] aszu:
This is very different to what I am observing, I will post some data once I have enough them.

But generally I am very impressed by this phone, it is *almost* perfect:

1. Spectacular, iPhone-level build quality: metal, aluminium, glass. 'Bezeless' design (not really, but good enough). This phone could easily be sold as a 'flagship' device costing 2x more.

2. One of the best LCD displays I have ever seen on the phone - and properly calibrated too. It is a wide-gamut display that visibly exceeds sRGB and covers most of the Adobe RGB colorspace. However, since no one has really any idea how to support those wide-gamut displays properly (especially on Android where any kind of color management framework does not exist), the end result is that all the colors are deeper and more saturated - which is not exactly a correct representation, but it looks very nice nevertheless (think of OLED displays that being wide-gamut are suffering from the same 'problem'). Contrast ratio and blacks are great too - I will try to post some measurements later. Maximum brightness is OK, but not extraordinary, I suspect this is because the display is actually calibrated, as opposed to many screens that use too much blue component to make them look brighter.

3. Audio: remarkable. Crystal clear calls, shockingly good speaker (for a phone) and simply stunning headphone output (pretty much the best I have ever heard on the phone, and I have tried a lot of them - just make sure you disable '3D sound' and similar 'enhancers' in Dolby Atmos / DSP plugin)

4. It has multi-color notification LED (against the stupid current trend to not include them), IR blaster (gimmick, but could be useful for some), noise-cancelling microphone, dual-SIM (of course), physical mute switch (I would very much prefer physical camera button instead, but why not). There are 'physical' navigation buttons (which I prefer) as opposed to the onscreen buttons that often 'steal' real estate of the display.

5. USB Type C socket - very sturdy, hight quality, reversible connector and it actually delivers 1.9A of current during charge (measured), which means it should be absolutely possible to charge the battery from empty to full in less than 2 hours (it takes 4 hours in Jiayu S3...). It is just not popular at all yet, so if you travel make sure you always have the cable with you.

6. EUI Android - a bit of a mixed feelings about it, as I prefer pure stock, but the OS is very clean, fluid and well optimized. Very good vendor support so far, they release 'experimental' updates weekly and 'stable' releases every month. The phone is very China-centric, with plethora of Chinese bloat included, so installation of 'decrapified' ROM like BB72 is almost a must. However, after configuring Google Now Launcher I can absolutely live with the OS, it just requires some time to adjust.

7. 4K video recording and with solid bitrate/quality. Photos looks good (haven't done many tests yet), although flash is a bit temperamental and too bright at times (it might be fixed in the upcoming update).

8. CPU, RAM, blah, Helio X10, blah, blah, IMX, blah essentially top of the line specs (not that it matters, optimized software is much more important). It gets > 50K in Antutu benchmark, but this does not really mean anything (Be Touch 2 scores very similar and it is a laggy mess)

Drawbacks:

1. No removable battery (I am fine with this, it improves build quality and minimizes chances that your battery gets swapped for a inferior clone by some unethical vendor)

2. No SD card - a bit of a letdown, get 32GB version if you think you might need more space, it is only 20$ more (I think 16GB version should not exist in the first place in 2015, when 16GB SD card costs 5$).

3. No NFC (like if anyone cares...), no wireless charging (would be nice to have some alternative to not-yet-popular USB Type C)

4. No LTE Band 20 (a bit of a shame)

5. Mediatek standby power management is still a mess and drains battery much faster than it should (plenty of EINT, etc wakelocks, especially with WiFi on), not sure if this is going to be ever fixed. General battery life is just OK, very similar to Jiayu S3, it gets you through the day and 4-5h of SoT is possible.

It is a superb phone, has true 'flagship' feel to it. If you can live with the cons, it is so much better option than Elephone/Ulephone overpromised products for not much more money. However, it is also twice as much as Lenovo K3 Note, but I think amazing quality alone justifies this.
