Here's my battery stats. Knowing that GPS on half the time, data on, a bit of WiFi hot-spot, YouTube, Snapchat camera and call.
I generally avoid going under 15-20%

I'm testing MMX weekly ROM v21.6.23 (that is a cleaned version of the corresponding miui.eu ROM), and I must confess that I get a real improvement of the power consumption over miui.eu especially in standby (0.12%/h during the night)
I think it worths to be tested.

1. Trigger bootloader unlock process.
2. Wait for 168 hours.
3. Unlock the bootloader.
4. Download MiuiMix rom and TWRP image.
5. Copy over MiuiMix rom to internal storage.
6. Boot into Fastboot.
7. From Fastboot, boot into TWRP image.
8. In TWRP install MiuiMix rom.
9. After installation done in TWRP, wipe cache and data before rebooting to system.
10. Enjoy!

*You might want to backup all things you need before installing the MiuiMix rom*

Im still on stock and battery life varies, mostly its around 5-9hr SOT but the biggest culprit is 'other apps' using the same or more battery than total SOT. like today its 5hr sot from 92-18% and other apps has the same amount of mah used as screen. Im leaning towards custom rom ...

Well this worked better than I expected to be honest lol

Specially I think after disabling print services and removing some of the bloatware (most of them being the Xiaomi collecting your data)

Could you tell us what exactly have you disabled/uninstalled? Thanks in advance.
I can't remember exactly, wish it had a log or something lol, but the ones I remember are:

Analytics.
App Vault
Catchlog
Facebook (reinstalled from play store)

HybridAccessory
Joyose
MSA
Quickball

And followed from the main post, the disabling of printing services and game turbo app

I've using the phone now today and it's just incredible how much difference is with those apps on and off in battery

i think this is miui bug. It actually stores more battery at 100% thus making it looks like 100% can hold longer than usual. Can you try from <90% battery charge and leave it overnight?

    Hello guys, I want to tell you the adjustments that I have made to my Poco F3 and that have improved the battery consumption.
    For those who have a very high battery consumption in principle with the Poco F3 inactive, I recommend doing this before starting step 1:
    Reinstall the rom again, we go to Settings / About the phone / Miui version, where the number 12 is, we press and at the top in the 3 points we download the last package, which is the one we have, we reinstall it and we start with step 1 .

    I would be grateful if you could comment on how things went with them. Greetings.

    1.- DEACTIVATE AUTOMATIC UPDATES.

    In this way we will avoid that the mobile is constantly looking for updates and therefore consuming battery.
    1.1- We go to the Play Store and in Settings / General / Update applications automatically, we mark not update applications automatically.
    1.2- Once this is done, we go to the Miui updates. We follow the route Settings / About the phone, click on the number 12 that is in the upper left as when we want to update
    and then in the three points that appear in the upper right, we go to the update settings option and deactivate download automatically.

    2.- DEACTIVATE THE WIFI ASSISTANT.

    This option allows the mobile to automatically change the network, without us having to be aware of it, but it uses the battery unnecessarily. We are going to configure it to do it manually.
    We follow the path Adjust / Wifi / Wi-Fi Assistant, enter and deactivate the option to select the best networks automatically.

    3.- DEACTIVATE THE GAME TURBO.

    This option is aimed at those users who do not use the phone to play, if so, deactivate it because it uses a lot of battery. I do not play much, rather little, even so I do not have it deactivated.
    We go to Settings and in the search bar type game turbo. Mark the 2nd option that of Game Turbo Security, it will take you to the app, once inside, mark options that are next to the + sign, at the top right. Once inside, uncheck the Game Turbo option, it is the first.

    4.-DEACTIVATE THE PRINTING SERVICES.

    We have these services to connect to printers active all the time and the phone will be constantly looking for printers so that we can connect.
    We go to Settings and at the top in the search bar we will write print. Click on the only option that comes out, now click on System printing services, once inside we will deactivate it. We will see that on the screen below, we have a blue bar with a text that says looking for printers in this way we prevent it from constantly searching.

    5.-REMOVE BLOATWARE:

    I have removed the following but it depends on each one, they could remove more.
    Analytics.
    Android Accessibility Suite
    App Vault
    Browser
    Catchlog

    Yellow Pages

    OTHER ADDITIONAL SETTINGS.

    Let's go Developer Options.

    -Registry Buffer Size, I have it set to 1 mega.
    -Window animation level / Transitions animation level / Transition duration level. All three are by default at 1x, lower them to 0.5x.
    -Display: Manual brightness, almost full, in dark mode
    -Screen / Color scheme in Saturated.
    -Screen / IA image engine, here both IA HDR enhancement and MEMC I have them activated, although they increase consumption they are worth it, the screen improves, both visually and in video viewing.

    New edition on 04-22-2021: In addition to the previous additional settings, the refresh rate of the screen can also be lowered from 120Hz to 90Hz, you can see it here:

    People doing the debloating thing first time might want to DEACTIVATE the packages rather than UNISTALLING them. I say this because if anything breaks in the MIUI after debloating you can always try to find and enable the package that broke it.

    I do this. I DEACTIVATE the bloated apps, use the phone for 3 4 days and if there are no issues I UNINSTALL them.

    First post (April 20th 15:20):
    Thank you spiral5 for your contribution.

    Today my Poco F3 was updated (it had a battery drain problem) and it seems that now I have problems reporting, because since 8:30 (full charged) it only shows 99%. This is crazy.

    I have removed everything you commented (apart from Mi account before reading you) but I would like to know if all the bloatware you wrote can be eliminated "legally" or you had to use an additional tool like ADB or similar.

    Again, thank you very much for your input! I couldn't even imagine that this had a printing service too ... damn ...

    Second post (April 20th 15:27):
    "Before" and "After" screenshots (before clean all bloatware)

    I don't believe that after 7 hours it has 99% battery left. Stats was reseted after reboot (I rebooted the phone because I couldn't believe that stats).



    Update (today):
    27'5h uptime, 62% battery left. Soooo coool.
