Hello guys, i'm having a common and a strange problem with my mi8.
The common one is the not so good battery + drain with miui10+android9 on mi8, i did every tweak i was able to find, i disabled the non interactive scene, i set the preferred network as LTE/WCDMA and the battery improved a little but the main problem, that i can't figure it out, is that my phone, even when unused "during the day but also during the night while on airplane mode" keep activate his self when the screen is off.
I thought it was a problem caused by the ROM "i was using the xiaomi.eu stable" or some installed apps, so i decided to deep wipe everything and install the Global Stable with myflash but i'm having the same behaviour, even right after the format with no app installed, just logged in the google and xiaomi account.

What do you think is the problem here ?
firmware
You could try global beta, i used to be on global stable with 5 hours sot and when I flashed global beta 8.12.20 It raised to 6-7 sot

Also I have a standby battery drain when I'm somewhere with bad reception, it might have something to do with your problem.
Stand-by drain comparison analysis
Maybe this is too much.. (35% discharge in 13 hours idle!). Were you on LTE/WCDMA? Bear in mind that just flashed MIUI has default options to search for more Wi-Fi networks, Google Nearby, Google Assistant, Ok Google, NFC, security settings,.... that may keep it awake.
Anyway, I think this phone discharges too much during night idle on cellullar connectivity even in LTE/WCDMA and good coverage (88 dBm). With teaked settings, it discharges itself 7% of battery in exact 7 hours, idle, which is better, but too much IMHO. (Airplane/off mode ~1%). System2Panel reports Cell Connectivity to drain 45 mAh in this time. The curious thing is that, another phone, Mi A1, at the same 7 hours idle, much less tweaked, same provider (even worse LTE signal, 96 dBm), discharges only 3% and indicates 7 mAh cell connectivity. That is, Mi A1 consumes less than half at idle. We're talking 3% to 7% discharge difference, not much, but cell stanby energy is consistently 6 times more, which is why long term, discharges more. (Average 9% total in 57 hrs, which is overall too much). More bellow:
Every two hours, you can see on Mi 8 graph, there are about 10 minutes peaks of 200 mA discharge (representing 1% in 35 minutes). Notice Mi A1 keeps flat on average. Cell standby is 9% total all the time on Mi 8, high enough, but the drain peaks doesn't come from cell, but every 10-minute unknown proces! Additionally, In a flat 30-minute zoom, Mi A1 cell standby is minimum 0.50 mAh (can't upload a 5th image), while Mi 8 is minimum 3.0 mAh, exactly 6 times.
Call me obsessed but I paid flagship money for a device that discharges on average 10% by night for me. Yes, I know, airplane mode, but a nice Mi A1 with less battery discharges less by night, and consistently cell connectivity is 6 times more in mAh on Mi 8. (Snapdragon 845 is idle, can't drain)
Note: I am on Xiaomi.eu 9.1.3, Sphynx kernel 2.3, debloated apks.

What do you mean ? I tried both the Xiaomi.eu stable and the Global Stable with the same behaviour but a lot of people with the global stable didn't have my issue :c

I suspect that the problem is somehow related to this, but i don't know what to change or fix.
Ok google disabled, no NFC but i have no idea where to find and how to set the are three options " Wi-Fi networks, Google Nearby, Google Assistant, ".
Can you please guide me ?

Yeah my point is that global beta 8.12.20 has better battery than the global stable at this point

I have already read those posts but this is not the point, i kind fixed the drain related to the bugged "scene manager" and the mobile antenna, the problem is the incredible number of activation with the display off "see picture below"

I'm sorry but it is not solved yet in those threads. Scena Manager doesn't fix it. I don't deny there are activations with display off, but the consumption of the cell connectivity is high according to my tests, compared to other phones. It is consistent to me cell consumption with battery drain overnight.
Many people say cell standby takes high %.

Idle drain is high but yours is higher then mine, i'm on last stable (locked Boot Loader) and my drain during night with everything turned ON is about ~0.5% / Hr
This drops to 0.3 if i set the airplane mode and re-enable the WiFi. And goes to 0.0 if i disable the wifi too.
(OFC i've debloated the hell out of it)
One thing that could help, if you haven't already, turn off the interactive scene under battery - scenes

That 0.5%/hr, is average Screen Off discharge summary or the minimum discharge segment in Battery Historian?
Not sure if this is applicable to us. Though, I should leave this here.

4. Battery drainning issue of Android P
We have found some framework issues and optimized in opent beta. However some 3rd party apps will cause to battery draining as well. It would be very helpful if POCO users could share us your log info for analysis.

I envy you... It's so low.. and locked unrooted. I am highly debloated too, root and custom kernel. I don't know if it's about LTE reception...

Don't envy me, this device is a mess... Cell drain is really too much, even with good signal reception.
Tomorrow I'll share that bug report if you want.
Guys, I am having this issue with mine and I have no idea how to fix...could someone please help?

Hi, well, I am on MIUI 3.28 (highly debloated) and my graph is as follows: I made 7:30 hours SoT yesterday. Phone activity is in sync with screen on although there are wakeups from wakelocks such as Google push services every 20 minutes or so. As you see my cell standby is 5-6% so I'm finally happy. It lasts on average for two days with good usage for me. I'm in peace now.:victory:
I am software version shown in ss
I just bought the phone and only getting sot 30 mins for 10% of battery consumption i got like 4 and half hour of sot for 73% battery consumption i thought x2 pro have around 8 hr sot help me it's frustrating
Well that calculates to more than 6h SOT, which isn't that unrealistic if you used 4g and max screen brightness all the time, but there might be something draining the battery. Check the usage details. I see you use something connected to bluetooth so that might be causing the issue.
Bro i was using the brightness at 27% and nothing was connected to the Bluetooth
I installed betterbatterystats (bbs) xda edition and gsam battery app with adb rights. So you can see the deep sleep with bbs and the times of dot/phone time/ect and which app use how many ampere.
In this charging time I get 4,5 hours dot with 40 hours phone is on. I have now 34%.
Debloating, netguard firewall, no energy saving, always 90 hz.
Also i am having fps dropping issue during online gaming like pubgm or codm
What should i do to get normal 60 fps as this phone has 855+ so i can get 60 fps normally
I'm having even worse SOT and I have the same realme ui version.
I'm not as much hardcore user as a lot of you and looking at 4k mah battery I thought that I will be getting at least 7h SOT.
I'm not playing any games, right now most of the time phone is connected to wifi. What should I do? Debloat my phone? Is it somehow dangerous for my software? Can i ever go back to normal version?
location services destroyes battery on this device
i disable it for one day just to see the difference and it went from 4 hours SOT to 6 hours plus
always talking full brightness wifi some 4g 90hz
and from 100% to 1%
You have like almost 30 hours of standby, and if you use always on display, then that's at least 30% on that. If you consider this then it doesn't look that bad. You do the math. The other guy's stats concern me more.
You will need to make some adjustments, battery can be excellent but you have to be realistic,
Check out App quick freeze and freeze the apps you don't use.
Dark mode,
AOD off,Screen light effects off,
You just got the phone,tinker with it a while to see,
Also battery will drain a lot when your setting up the first day
Help everybody,
I've bought the phone 3 days ago. Battery life is very bad, getting around 3 hrs SOT using Spotify, Facebook, Reddit and Instagram. Mobile data is always on, Bluetooth was on for 2 hours
Is there any way to improve battery life?

Ne Firmware should make things even better
I would try recalibrating the battery, I have found that it lasts very long after hitting 1%, and others have also found that the phone continues charging for a bit after hitting 100% (even with the LED being green). So completely drain the phone, let it charge to 100% and when it hits 100%, give it like half an hour more.
Also, disabling 5G in the Network settings should help. If you are underground (with bad cell signal), I would suggest you enable Airplane mode and then enable Wifi. This will prevent the phone from constantly searching for a better cell signal. Doing this helped me reduce idle drain.
Last night with a few videos + today, I got a total of 3h40 at 120hz durable mode (Charge limit to 90% and the phone is still at 15% battery left).

I got it via OTA.
Also you probably need to set up other (was tired yesterday evening):
dynamic mode
5g off
90 Hz Display (I don't really see the difference between 90/120)
Wifi, BT, location always on
I get around 7 h of SOT fully charged and 5 hours brings me from bed to bed.
Yeah 5g off makes a lot of difference to me. I also use Naptime.
I see a big change with location off. Just put it on qith quick toggle when needed. The standby is much much better with just this change for me. I have 5G because my plan doesn't allow it either way.
As others said, it's about 5-6 SoT, normal use on its stock Asus Android OS.
After installing LineageOS on now I got 8+ SoT.
Due to the clean LineageOS, 60Hz screen refreah rate, battery saver always on, no google spying services installed, 100% google free,no blotware, no whatsapp no facebook...
Phone now lasts me comfortably a full day of work (sometimes day and half).
I use it for work not as my playstation.
I'm super happy.
Btw, your post is duplicate with other post, That post has other feedbacks that may help you, better to stick to that post.
