The right custom ROM + Kernel for Battery Life and Performance - Xiaomi Poco F1 Questions & Answers

Hi there,
i read a lot about custom roms and kernels.
So now I'm not sure which rom+kernel gives you all the features like IR-Faceunlock, fingerprint scanner and a overall smooth and stable experience.
Here is what i need:
+ Stable
+ IR-Faceunlock
+ WiFi
+ Calling
+ fingerprint scanner
+ underclocking CPU and GPU ( I don't play any games like PUBG)
+ improved Batterylife for a lot more then 8 hours SOT
+ GCAM support
+ 4kVideos + Slowmotion
+ Notification icons
and here is what i do:
+ Browsing
+ reading Mails
+ Whatsapp
+ Photos
What i read so far is, that AEX Pie + Derp kernel should work for my profile.
Also is there a way not to use GAPPS and go with MicroG for better batterylife?
Maybe you can tell me your favorite rom and kernel or give me some hints.
Thank you and best regards.

Simply stay on stock rom

Stock Rom is just OK...
But i come from aex (motog5plus) pie and it was very stable and i liked the customize my mobilephone.
Also i read that stock miui comes with bloatware. Is there a way to eliminate that?

Pixel Experience Rom + Franco kernel (with manger).
PE is the most stable Rom yet (imo).
Network coverage is best among all custom roms.
Fingerprint+ ir scanner works (little slower than stock miui).
User interference is butter smooth and almost bug free to be used as a daily driver.
Gcam is inbuilt ( including playmojis).
Use latest miui stock camera magisk module for 4k/slow-motion.
Use Franco kernel manger app for underclocking cpu/gpu.
On the downside, it doesn't offer that much of customisations. All features for notifications work, but I would have been happier if there was a way to customise status bar icon.
Go for nitrogen os for better customisation options. Lineage OS for better performance. But they are little buggy sometimes.
I think PE is best for you according to your user needs.

Xiaomi eu for stock miui.
Lineage OS or pixel exprience with franco or sphinx kernel should be good/enough for that you want.

Just to throw in my 2cents here.
I've used PE rom for a while. SOT was around 6hours, which some video, music, bluetooth, wifi, data on etc.
However, moved back to stock rom with the extreme kernel (not overclocked standard 60ghz) and I'm now at over 8 hours SOT.
Waiting for the phone to die, so far its been 26 hours and I have 22% battery left. Must add that my usage wasn't that heavy yet. However will update in a few days again.

just to clarify, the 60 ghz of extreme kernel you're mentioning has nothing to do with overclock; it's just the refresh rate of the screen and it is not affecting battery performances; you could use also 70 ghz if your display support it without any drop of battery performances.

Havoc 2.2 and twisted kernel 4.1.
Stability and Customization. SOT - 7-8 hrs.
or
Oxygen OS with default kernel.
Stable and Smooth.
SOT - 8hrs.
I'm using both simultaneously (Multi-ROM).

Good luck.
Well, I would suggest you to try OxygenOS port with Sphinx kernel. It's super smooth and battery life is great, without crazy tweaks and OCing every damn thing.

hmm... a lot input for me.
Then I'm down to 2 variations:
Miui.eu + derp kernel vs. Oxygen OS port with Sphinx Kernel
Now I have to test which one works better for me. But i have to wait, cause my poco f1 is not rooted yet.
Does oxygen OS has all features which miui offers?
Thank you

Well, OOS has all features I need. Maybe you'll miss something related to MIUI.

Obviously varies with usage. But users related around 8~10h.
Mine is less because I live in a forgotten Brazil province and carrrier signal is poor.
