Really disappointed of the battery life. Wasn't the 888 supposed to be more battery efficient than the 865?
Light usage, not even 6h of SOT with 13% left. With indoor use (low brightness, wifi) , 120hz FHD+.
Compared to my OnePlus 8T, i can get slightly more than 7h of SOT...

What's your battery life ?

Yes it supposed to be more battery efficient than the 865 but it isn't , at least for now. maybe they will tweak it in next few months. we will see. But you can do some tweaks also and you should get improvement. I see some people complaining about chrome using a lot of battery so I would uninstall it for the start and use some other browser , I can recommend kiwi with built in ad blocker and dark theme and is super light. But there's many other. Also today I was experimenting with dynamic wallpapers and I saw significant battery drain which was very noticeable so I just put black background. I never went to battery to follow what's going on , my device easily go through the day with normal use. I would say from 7 to 23 my battery goes from 100% to 10 - 30% depending on the use. For me I am very satisfied with the battery life.

@Asnamus your screenshots are not really helpful and funny, cuz you charge your phone @zacer I don't know what you try to do but why you can't provide screenshots? I will tell you why.

With stock global rom and also with beta 12.5 the battery life on Mi11 is really bad.
Staying home, almost only wifi and things like whatsapp, firefox, etc. without gaming or camera you will get about 6h SOT with 15h standby. If you are not home and use mobile data it's the worst battery life ever. It's like a Galaxy S6.

They will never fix this because the device is already +3 months old.

Today I will do the test and post , I am also interested what will be the result. My screen shot yesterday is a honest screen shot at that moment. It was more about how much Kiwi consump battery comparing to Crome and Themes (dynamic wallpapers)

@Linuxkek I didn't charge you can believe me or not. I just made that screenshot for my friend, sent him, and connected to charger(so the stats has been reset) . After that I saw this thread on forum and I pasted my result.

Facebook app is causing random heating and battery drain.
Yesterday I had this issue and discovered that facebook app caused it. So I uninstalled it and I use Maki Plus for facebook. Great app. I must say that I got around 6h sot yesterday with this problem.

The word that describes my experience with this phone battery life is disappointment.

I am using it at FHD+ and 120Hz and I get 3,30-4 h of SOT. I does not matter if I use dark mode or not and I have already debloated the device.

I don´t think this is a hardware issue anyways so I hope it gets some kind of solution.

I will return it, really too bad. Miui is full of bugs, even with lot of compromises in my usage (dark mode, kiwi browser with night mode, black wallpaper...) Still get bad battery life.
Only 9h with 6h of SOT, whereas for a very similar usage, on my OnePlus 8T, i can get 24h with 8h of SOT.

According to Anandtech, they confirm that there is definitly something wrong about battery life, but they can't tell if it's hardware or software issue.
It's definitely this "other". I don't know what a construction is this, the weirdest thing is that you can't find any information about, I never saw it on any other phone, and it sucks your battery off. I don't use games, any social, no demanding graphic, and I can't imagine what could be possibly hidden inside. Besides it waste the battery it looks shady.

i am not sure why but with my mi11 i get a much higher SOT as with my Op8 Pro
the main difference

my Op8 Pro i restored from an oldbackup
my Mi11 i completely installed new every app, every setting

also i searched a little MIUI 12 Battery saving guide, applied some of the things which did not bother me too much and voila, i end up with 7+h SOT a day incl some walks with GPS, listen podcasts via bluetooth

FHD and 120Hz settings


i am satisfied with that, my OP8 Pro which i used the same only got me like 4,5h on a good day

I was on the latest cn rom waiting for the bootloader unlocking. Battery life was great. Averaging 10-9 hours of intense use.

After flashing eu 21.3.11 rom, the state of battery has deteriorated quite alot. I need to charge it at least twice to last for a whole day.

Is there a possibility to downgrade the rom to the previous version as I have seen people complaining after updating, or should I just for a fix in the upcoming update?

    For all the people complaining about battery life I got 12+ hours of SOT today !
    I have done some battery testing today after applying some more tweaks to the device and I got really good results. Note that it is a rainy day here today and I am on auto brightness.
    AI image engine is turned all off. But it is still on 120Hz and WQHD.
    And I was using device mostly for watching movies, videos from YouTube, Netflix and some 4k movie I had on the device.
    Some of the tweaks that I applied I found here:
    https://www.facebook.com/groups/XiaomiDeutschland/permalink/1126756584403672
    Thanks @qvert for posting this.
    PS choose your tweaks wisely!
    And an advice on how to have a long healthy life for your battery:
    Charge your phone when it gets down to 10% - 20% up to 80% - 90%
    Use a smaller wattage charger , I use 5w as it doesn't heat up the battery at all. Only use fast charging when you are in need.

    I think that is the problem, try a clean install (install the apps manually). For me solved the problem.
    Before the clean install I had to charge the phone 2 times during the day (with about 3-4h of screen)
