unable to fix stand-by drain

Hey guys
I am having a serious battery problem with my Chinese K20 Pro. I am not sure whether or not it has something to do with the sensor issues I've got with that phone (compass always twisting, see thread here: https://forum.xda-developers.com/k20-pro/help/k20-pro-compass-spins-calibrates-t3972249)
The point is, my phone is constantly draining battery in the range of up to 40% over night. Even in airplane- and/or ultra battery saving mode and also on a freshly setup device using miflash with a stock fastboot ROM without a single additional app installed. So I can exclude it's caused by any app wakelocks.
I am really clueless now about what else I can do.

Maybe you should try uninstalling Yatse app once if you haven't tried it already.

Its just a sample screenshot. In this case yatze was only active for 4 seconds. as i said, the same drain occurs when no apps at all are installed

I really think it's a hardware problem. I got the sensors issue fixed but battery drain is still huge

I got the same Issue since MIUI 11. irritating, will go back to miui 10 and test

But I had MIUI 11 running brfore without that problem

Guys when you pass from one version of android to new one, it is the best to clean flash, not just update from a9 to a10.
I am on miui 11 eu global stable android 10 and no drain of battery. since 2.5 days i am on 66% of battery

I have always clean flashed all tested ROM's. Now I have just tried a MIUI 10 ROM (also clean flashed) and guess what!?

10 months trying fixing battery drain (k20 pro/mi9t pro)

So, It has been 10 months of headaches. Bought in july 2019, for two months best phone ever, battery lasted 2 days, near to 1-2% of battery drain at night on standby. After installing miui 11, the battery said "bye bye". 3h screentime, need to charge the phone twice a day, losing 10%/h on standby.
What I tried is:
-havoc os
-xiaomi.eu Miui 11-12. beta and stable
-Evolution x
-latest firmware always/reinstalled latest firmware-vendor
-always clean install wiping everything
-new battery 2 months ago (same results, no difference at all)
-no app is draining battery in the settings
-unistalled analytics and miui daemon (msa not found on xiaomi.eu roms)
the phone goes in deep sleep as you can see in the photos in the link below.
Gps, wifi and bt always on. Tried switching them off, just 1% less of battery drain on standby.
Bought a broken mi 9t pro just to try switching motherboards, just to try that it isn't a electric or physical issue with the phone, but can't do it that right now, waiting the new screen to test the broken phone.

Any suggestion?

Have you tested putting the phone on standby in airplane mode? This is unlikely to be the root of the issue but poor cellular signal may negatively impact the battery life.

tried that also, nothing change. Always 4%+/h of drain in standby.

I've pretty same problem, and it's really strange...
I've a Mi 9T Pro, bought not more than 2 months ago brand new, all stock.
I leave on just the phone active during the night, in both SIM cards: no bt, no wifi, no mobile data active.
The battery drain is around 10%, which is really insane considered that before my 3 years old phone, an Honor 8, in same conditions, was draining not more than 4%.
In general battery is draining really too much.
Passed OTA from MIUI 11 to 12, but the drainage is same.
I'd like to understand what is the issue causing that.

Dude. Same issue for me. It's only 6 months old. I noticed battery loss on miui just a month into purchase. I'd suggest pick a rom without Gapps or one with microG and try them out. I was using evo X and getting around 6-7 hrs SOT. Once I moved to Aim and Omni I started getting 9-10 SOT. I think Gapps is mostly the culprit. Miui sucks these days. I tried miui 12 and was utterly disappointed. Try this and you might just start loving your phone again. I'd say go for Omni and setup microG, install greenify, turn off battery optimisations only for essential messaging apps and turn on aggressive doze. Your sure to see a difference

Try havoc os 3.7 , try it without social apps like instagram, facebook and other crap.
Mine usually lasts around 3 days with 6h sot.
I also have gps , bt , sync and data always on

Tried gms doze? Disabling autostart of apps in miui?

The point, guys, is not to try different ROMs or install apps or not to use social medias because the phone drains battery...
The point is that the phone should not drain battery that much at all!
I think Xiaomi should care more of the firmwares released, trying harder to fix bugs that might be important rather than releasing new features.
My own opinion.
PS. Last night i checked the battery drain thoroughly: from 1.30 am to 7.30 am, just both SIM cards on to receive eventually phone calls, no WiFi, no BT, no internet connection, ND mode active = battery drained 9%
It is not acceptable!!

Clear all apps from memory, clear cache of 'Google Frameworks' and 'Google Play Services' don't restart the phone
I do this whenever I remember usually every few days and get great SOT around 9-11 hours. Although Accubattery says my battery health is 3300 of the 4000 as I've had it for a while and I'm a very very heavy user. Brand new was getting closer to 10-12 hours doing this same method.
I found it by someone posting a random comment somewhere in this forum just don't know who or where I saw it. They gave no explanation as to why it works but just what they did and its worked immediately. Note I'm still on MIUI 11.0.3 Global as I'm nervous this method won't be as effective in more newer MIUI Versions.
If you have a newer version please try and let me know if it still works, hope this helps
Also I reinstall MIUI through the phone after clean flashing it via Mi Flash
That is that I flash clean (erase storage but not lock bootloader) from Mi Flash and then go to the update settings of the phone and then press the 3 dots at the top left and "download latest update" and then install it again
This helped when I was on MIUI 10.X.X but do it out of habit so not sure if it helped for MIUI 11.0.03
edit: Reinstall method

Similar issue with my K20 Pro.
1. The battery backup on Android 9/MIUI 10 was giving me close to 1.5 days of backup of 7-8 hours of screen time.
2. It was decreased to 6-6.5 in Android 10/MIUI 11
3. Now with MIUI 12 it is reduced to 6 hours and with need of charging two times in a single day. All this with no social media apps, only Whatsapp, Youtube, Prime Video, Spotify and MS outlook, teams apps with regular usage. WIFI all the time, no GPS, 2-3 hours of Bluetooth. plus tried deboating MI apps.
So far I have tried PE, EVOX and EU roms but all gave me disappointing battery backup. The battery seems fine only on android pie so my assumption is that battery probably doesn't need replacement and more of xiaomi's firmware related issue on android 10.
It's so disappointing to see such a great piece of hardware holding back because of battery. I hope somebody find a good solution to this issue.

Question High battery drain

Hi guys. I am rocking CN version of Mi11 Ultra 12/256. It's currently on stable 12.0.10. i have allowed the application for notification and set up the system in my way to be usable by uninstalling most of the chinese ops that i was able to. Now, i can see that the battery drains abnormally it seems that the phone doesn't go to deep sleep. The second highest usage stats is android system.

Awesome phone!
It's a bit old but you can use Wakelock detector to see what is preventing your phone from going into deep sleep.
I'd also try to check the logcat to see if there is some system process working in the background continuously draining your battery.

I'm also looking at that graphic, it doesn't seem like Battery Drain is much at all. The phone has been active for 8 hours and it's around 80%? Doesn't seem bad to me.
Screen and Android System are the commonly the two most battery drainers if nothing else is cpu intensive.

Yes, but it was 8 hours overnight

Thanks for the input BTW, I'll definitely check wakelock. Maybe it's just me, but it seems it's draining in my eyes.

20% overnight is indeed too much... Might it had something to do with the debloat ? Did you uninstalled the Chinese aps via the getapp store or ADB ( disable or remove )?
After I upgraded to 12.0.13 my battery did drain a bit faster the very first couple of hours. ( background optimizations i Guess ).
Today I updated OTA to 12.5.
We'll see how this goes .
Good luck to you !

You probably already checked these settings but don't forget to disable AOD (if you don't need it), WiFI/Bluetooth scanning and WLAN Assistant too as thais will help reduce power consumption slightly.

I think its normal drain...the system drain is just there for example i debloated around 30 apps and its good

Last night with everything on as during the day ( Bluetooth, wifi, mobile data, gps, nfc, etc ) it drained only 4%.
For me it's a new record

Here is mine

I uninstalled some chinese apps traditionally, so didn't use ADB download method.

Is the same that i did when i got my phone.
I went in the getapps store ( xiaomi store ) and uninstalled everything that i could there
Maibe you have some other software then installed , that isn't perfectly optimized.
My best advice is to go ahead and clear the full data for ALL the aps you are using ( including google playstore and the related services )
Also you can try to keeps the phone plugged during a night or two ( without touching it )
As i read somewhere, if the system sees that it has full battery and is plugged in after a while ( more than 20 min or so ) will start the optimizations of apps/general system ( otherwise it will try to do the optimizations during the day when it's in standby and above certain battery level )
I had some success doing this on my mi9 with xiaomi.eu, but in that case the rom version had a known battery drain
Do you have the miui optimizations disabled ( i left it enabled and haven't touched it ).
Have no issues with batter drain so far.
Good luck and keep us posted !

Did you ever fix the issue with the high battery drainage? I got my global unit last Friday (running 12.0.1) and I feel like I'm seeing a similar thing. Wanted to see what other users were averaging for screen on time. Is around 5hours of SOT with 120Hz and WQHD+ enabled decent?

I did, bu flashing EU rom 5hours SOT with both options turned on is decent. And recharging the bat takes minutes

Same.. i am on global with 12.0.6.
Batt drain is very bad, overnight, from 100% at 1am to 88% at 8am.
i have scheduled batt saver to turn on.
i am getting average 4 to 5+ SOT with 90hz and wqhd,

If it would happen to me i would check every app behavior closely ( battery app and maybe a third party battery monitor like accubattery that i'm using ), see if i find anything suspicious and if nothing is out of the ordinary i would do a complete reset, reinstall again and if this doesn't work, install xiaomi.eu stable at the very least .
But that's just me
on a side note, on my china unit when i was on the 12.0 the experience was not so great...
As soon as the 12.5 update came i could see a major improvement.
So maybe have a bit more patience until 12.5 will launch for global versions as well, all tough china will always be ahead in terms of improvement...which leads me to xiaomi.eu, again.

i had the 12.5 CN rom on the mi 10 ultra, it was bad, notifications were delayed or not coming in at all until i opened the app, like whatsapp.
it was working fine in 12.0
that is why i decided to go back to global rom

I don't know about mi 10 ultra but i can tell you that for me on the mi 11 ultra, it's very good.
Good luck !

Question Battery Xiaomi Redmi Note 10 Pro - Miui 14

hi, a question, after updating to Miui 14, the battery in your Xiaomi Redmi Note 10 Pro discharges very quickly (at night it is 20 to 30%).

No. There is no discernible change from the previous version (EEA ROM).
On a seperate note I see that Xiaomi have now removed (hidden?) "cell standby" from battery stats to stop people, like me, moaning about it!

I noticed the same, before the update it discharged like 10% at night, and now it's like 20%

Try to reflash miui 14.0.2 EEA with Miflash tool and check option : clean all to be relax because your phone will be very clean and like new after that if the issue of battery drain stay you should try plan B and i think the problem will be resolved plan B is calibrat your batterie try to using your phone until it turns off completely and wait 3 hours while it is turned off after that plug in without turn it on until you see 100% icon battery in the dark page and try to give it another 3 hours after that plug out and power on your phone and use it until 15% ..and voilà your batterie is fresh and calibrate and happy

Thank you, I will try it and I hope it works. If I still face any issue, I will message you. You made my day. Today, I am so happy because when I was looking for your post online on google search, I also discovered https://studyclerk.com/thesis-writing website where I found essay writers who will help me with my thesis writing assignments. Now, I don't have to worry about my homework because I can simply take help from that website.

Question Screen usage not displayed anymore

Hello guys,
My mi 11 ultra, running MIUI 14 EEA ROM, does not display the screen on time in the battery usage section anymore.
i did not change any setting and it was working until yesterday.
now i only have the applications consumption and "other" at the end of the list.
and the items are not listed as per their usage anymore
is someone experiencing this ?

I have updated my wife’s mi 10 to MIUI 14 and screen usage is gone too … i foind it very weird to remove that since it is the best way to measure battery life…. Does anyone know if it can be added back ? Thank you

On my Mi 11 ultra with EliteRom (miui 14) i have Screen Usage. Dont know about the ROM u are using tho.
