[Xperia Z5 Compact General] TheEndHK:
Can you tell me more about Sony Wifi signal intelligent?

It's a bit hard to describe how poor of s6 memory management because for a light to medium user like me doesn't bother me much. Heavy users may face lagging all times and reloading apps, that will cost extra battery/cpu made the battery life get worse. To me, both phones the battery level don't have day and night different. The UFS 2.0 used on S6 is more advanced, os boot time and apps starting up or files read/write is all faster but the eMMC on Z5c is already faster than my Z1c.

86hrs vs. 73hrs pretty much reflected the real life, you get extra 10~20% juices, it's better but only slightly. The Z5c camera consume more battery than S6, I like to take much photo/video, you could expect in the end they will just got same battery(indeed S6 should get a bit more battery left when you are pure camera man).

Gaming isn't a problem now on S6, you can set for lower resolution and fps for each game. Save from lagging and power hogging.

The Z5c camera is still considered as beta stage in my opinions, I can't real make a comment until Android 6.0 out. In the earlier builds, the photo may even worse than my old Z1c in some specific conditions, now with camera 2.0 apk updated the photo quality finally surpassed Z1c all around. But the video part is still poor, especially my Z1c with 4k mod provides better quality and focusing speed over Z5c at low light. Sony only fixed the photo but forget video at this time. I didn't try out Panorama shot.

When it comes to the color reproduction, you don't have to worry about. Z5c does offer slightly warmer tone and vivid color but just in some shots it went off to cooler WB by accident. The S6 saturated is just way too over and Z5c much more balanced in my eyes though if you have time to play with Pro mode it could get better result on S6. In SA mode now you can adjust the brightness manually but still no touch to focus with auto AE. Very hard to shoot 100/200ISO at low light, this is just same with all other phones without OIS which isn't a fault of Z5c but 2015 Q4 flagship with this price range still no OIS is questionable.

This is my old S6 vs. Z5c campaign but the Z5c software is based on Camera 1.0 apk. On 2.0 it clearly got better result in terms of details and focus. I don't have time to run another test now, maybe I will do it again when 6.0 arrive on both phones.

I'll rate both phones with the same score since they got pros and cons. I want to sell out one but I'm stuck now very hard to make decision yet, waiting for 6.0 and I'll think it again later. I would recommend you to just stick with S6 if you want an easy to use and all-in-one camera like Panorama, OIS plus you don't care the over saturated color. The best way is to get a Z5c and test it by yourself and sell out one later like me but that would waste a bit of money.

EDIT: I've just updated to .200 build and found 4K video focus a bit better now but still have rooms to improve on speed and details.
