hey guys, the results are in in summary, MIUI.pro seems to be a TINY bit more performant and battery life friendly, although the differences are SO marginal that in the end it basically just comes down to what style and functionality you prefer!

Here are the results in detail:
Lineage OS 14.1 vs. MIUI.pro 7.12.14

Geekbench 4.2 average of three runs:
Single Core - 885.3 vs. 871.7
Multi Core - 4343 vs. 4254.3
Conclusion: Geekbench is a bit more performant than LOS

Antutu 6.3.7 average of three runs:
Total - 63268.7 vs. 63339.7
3D - 12321 vs. 12661.7
UX - 24452.7 vs. 24262.7
CPU - 21074.3 vs. 20964.3
RAM - 5420.7 vs. 5450.7
Conclusion: As before with Geekbench, CPU and UX are a bit more performant on LOS, whereas 3D, RAM and thus Total are a bit higher/better on MIUI.pro. I assume this is due to better graphics driver in MIUI.pro compared to the ported LOS version.

PCMark 2.0.3716 Work 2.0 Battery Life Test (Average of 143 runs)
Conditions: Run from 100% to 20% Battery, Screen brightness minimum (non-adaptive), Bluetooth/Wifi/GPS/Sync switched on
Battery Life - 23h24min vs. 23h33min
Total Score - 4645 vs. 4720
Web Browsing - 4923 vs. 4928
Video Editing - 5160 vs. 5227
Writing - 3875 vs. 4019
Photo Editing - 7264 vs. 7312
Data Manipulation - 3025 vs. 3093
Conclusion: MIUI.pro beats LOS in every aspect in this test. However, only the "Writing" Score is (barely) noticeable with a difference of 3.7%, whereas all other scores are within a range of 0.1 and 2.2 % difference and thus negligible.

Overall conclusion: LOS clocks in at 99.4% averaging all scores, which in turn means that MIUI.pro provides 0.6% better results.

So there you have it! What this means in my opinion: HUGE kudos to brother @xuefer in porting a LOS rom basically as performant and battery friendly as a custom rom based on stock MIUI firmware! I for one am most likely gonna go the LOS route just for the sake of that warm fuzzy feeling of running something TRULY custom on my Mi Max 2 besides, I prefer the style being closed to stock android

Cheers folks!

finally xiaomi released source code HERE

with this we can have our roms built from source (with everything working hopefully) instead of porting from other devices
@xuefer please have a look in to the kernel source

ha!

1) no kernel sources for mi max 2
2) lineage 15 (or rather 15.1, development for 15 was abandoned in favour of 15.1 based on oreo 8.1) doesnt even have a stable build yet!

so guys! ive got a very interesting visual comparison for you A total of four images:

1) Google Camera without HDR+ (basically stock Mi Max 2 picture quality)
2) Google Camera with HDR+
3) Google Camera with HDR+ Enhanced
4) Sony DSC-RX100 (my main camera I actually take pictures with since I still think smartphone cameras are crap )

All four pictures were taken in absolute darkness, with only the street lamps and some building lights for illumination, so basically worst case scenario for a camera.

What I can see:
1) GCam without HDR+ = lots of noise (especially the sky), mushy details, edges are slurry, all in all ugly picture
2) GCam with HDR+ = Greatly reduced noise, more details discernible (i.e. edges of plant leaves), colors look more accurate and not so washed out
3) GCam with HDR+ Enhanced = This is actually the first time I can see a difference to regular HDR+! Dark spots, including and especially the sky are a bit brighter and you can see more details. Its not much, but now I can finally say that HDR+ Enhanced is actually doing something
4) Sony DSC-RX100 = Yeah, this camera is in a league of its own compared with a smartphone camera There are no black or dark spots, details are discernible in all corners of the scene, colors are way more accurate, edges sharper. All in all, a much more accurate representation of what the human eye actually sees in that situation.

Conclusion: The GCam Port helps the Mi Max 2 camera immensely, more details are visible, colors more accurate, image quality is not slurry anymore, sharp edges and less noise! Still, in my book, there is no smartphone replacement for an actual camera such as my trusty DSC-RX100. Even though it was released back in June 2012 and is thus already 5.5 years old, its in a league of its own concerning image quality, especially in worst-case scenarios.

Nevertheless, great to see that we can pimp up our phone camera to make those spontaneous snapshots a bit more nice to look at!

What are your thoughts? Discuss!

1) Google Camera without HDR+

2) Google Camera with HDR+

3) Google Camera with HDR+ Enhanced

4) Sony DSC-RX100
