[Xperia Z1 Compact General] TheEndHK:
Guys, I've been bought Z5c to replace my Z1c(I also own a S6). Still very busying to test the z5c now, if you guys got any questions regarding Z5c feel free to ask me in this thread(if there are still any Z1c survivor here...).

My first impression vs. Z1c(and vs. S6):

1. Camera way faster and fixed the annoyed focus issue. The camera launch speed slightly slower than S6 but close to it. The focus speed at low light S6 a bit faster but Z5c already done a good job like 3x better and blow out Z1c completely.

2. Camera details isn't much better than Z1c only little improvements there, yet S6 got better details. Color, WB, AE is accurate than Z1c and S6, however sometimes you'll think that it is just too accurate and not as eye caught as Z1c/S6(they do more tweaking while Z5c towards to neutral side, the overall style still Sony and similar to Z1c).

3. Speaking to camera shutter lag and saving speed. S6 got instant speed in this area, Z5c slower but 3x faster than Z1c again.

4. Sceen is much better than Z1c like next generation with noticeably better color, WB, brightness, viewing angle and more clear. No doubt the 5.1" 2K on S6 is sharper, Z5c is just 720p but an exceptional quality one for this kind of resolution.

5. Support double tap to wake in stock rom. S6 needs root or custom kernel/rom to get this function.

6. Fingerprint recognition looks more sensitive than my S6, no worse than ip6/6s I think.

7. s810 on 720P is extremely fast, the smoothness is around the same with Exynos 7420 on S6. Kicks ass though the s800 on Z1c is already very fast but Z5c performs even much more responsively, no slower than S6 in my opinions. What the drawback on s810 it gets hot during heavy gaming or video recording but manged to an okay level for any s808/s810. If you want to get a cool device, I'm afraid Exynos 7420 is the only choice in 2015 until s820 comes out.

8. Battery life is identical to Z1c but since I've only got it for 3 days, I can't tell much at right now, it takes time to know. But it seems no worse than Z1c of 4.4.4/5.1.1, 2700mAh feed the s810 well. Expected to out perform Z1c when Android 6.0 arrive.

9. Solid build quality but I think S6 and Z1c more premium with metal bumper. Z5c goes to the fashion design, more young and motivative, not the same direction on S6/Z1c.

10. Speaker is superior. To be honest, S6 speaker also sounds out loudly but Z5c got very stereo feeling.

11. MicroSD supports up to 200GB, IPX67 rated, glove mode is still there. Finally no flag usb port with quick charge 2.0. USB-OTG is supported but you have to click USB connectivity to ask it to detect. S6 got an IR blaster which is also useful if you got many electronic devices at home or like to remote the TV in restaurant.

12. Internal storage speed lots quicker than Z1c though can't beat the more advanced emmc used on S6.

13. The front LED is as good as Z1c/S6, that LED notification is bad on Z3c.

14. After rebooting both Z5c/S6 got exactly 1GB free memory on stock rom(currently both of my Z5c/S6 running on stock rom without root) but I'll probably very soon to unlock and root Z5c bcoz I want to try to limit cpu speed to reduce heat.

My Z5c is running on latest firmware(second OTA) and it's been improved much on speed, those reviews on net are dated now. Sony said new camera update will come in this month so we'll see.
