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?
Sometimes, I lose too 0% battery overnight, but usually when that happens, I open my phone after, battery drain faster for a certain amount of % before going back to normal draining.

Did it from yesterday night to today, it went from 78% to 76% if I'm not mistaken.

Also 18% to 15% past-yesterday

Apparently it seems like Xiaomi.eu is the clear winner for guys who actually use the phone.
The only advantage I got from MiuiMix is that at some time during the night I got 0.17%/h compared to 0.3-0.4%/h on Xiaomi.eu ROM.
The SOT is around 5.5-6hs on Xiaomi.eu and around 5h or less on MiuiMix (on a 75-25% charge).
Here is my usage with MiuiMix with open wifi 24/7 (from 75 to 50):

Does anybody use any custom roms (ArrowOS, CrDroid, HavocOS) that can share his battery stats and SOT time?

It would be nice of we could at least have a rough verdict on which the winner is for battery life.

I don't think you can find a clear winner. It will depend each time on how the user uses his phone (like if only do browsing or watch serie or record videos etc).
I think any main ROM will give you a decent battery life.
Here's two stats for xiaomi.eu that I posted on specific topic. You can see 1h of sot difference. Within 2 days. So don't necessarily believe those stats? 🤔

Well yeah I don't think there is a clear difference while changing roms (Gone from stock to xiaomi.eu to miuimix to crdroid now). I guess I will probably stick with Xiaomi.eu (since I really like the UI) and throw in optimum kernel for the battery.

Seems like this is the best combo for me.

I would think that crdroid would offer the best battery life as it is very clean and sober. But it's relative to the kernel too indeed

Yeah I saw screenshots of people having 5%/h SOT with wifi 24/7 but I am getting 10% right now (like the other ROMS). Hopefully in a couple of days after a few charges I can get to this.
Hmm, 5%h/sot? I been using crdroid and I didn't saw anyone with that on crdroid group. And, u can't expect to have the same sot, different people, different usage.

Well here is a screenshot on what he sent me. I was really doubtful too but the screenshot seems noteworthy at least.
U can see by the %/hr in screen off that his phone has alot of crap running in the background. Besides, he's using low brightness and basically no apps at all. Don't try to reach something like that, u won't be able to if u use your phone.

I am the one in the photo and I have to tell you that the consumption is a little high in idle is because I have the honorband connected 24h and if you look there is the vpn key, which is the adguard app filtering the internet connection, it may also be because I usually listen to music.
If you look well you will see that the brightness is not that this low, if not that this in automatic and the apps I use are normal use (no game), mail, telegram, whatsapp, browser, calls, newpipe......

You don't have to be so smart about life mate.
Start using your phone instead of using 20% brightness all day and looking into a black wallpaper, cheers.

Cool topic. However, I have a problem with the "Logd" process, it is still draining my battery in F3. Can something be done about it? I was looking for answers but only found people who have the same problem.

    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
    Digital wellbeing
    Facebook
    Feedback
    Freeform
    Frequent phrases
    Games

    HybridAccessory
    Joyose

    Market Feedback Agent

    Mi pay
    Mi video
    MiConnectService
    MiPlayClient

    Quickball
    Scanner
    Screen Recorder
    Services & feedback
    SoterService
    Uniplay Service
    VsimCore
    Weather
    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:

    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.
    3
    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.

    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.
