Extreme WiFi battery drain solution! - Moto Z Questions & Answers

Ok, as many users are reporting the brand new moto z and the variants, like droid, force and play are having extremely WiFi battery drain, sometimes number one or number two on the Battery stats; in my case it was number one or two, somedays even higher consumption than the STO.
This is what worked for me, my phone is the Moto Z XT1650-03:
Go to settings/backup and restore/Reset Network config and apply it. This will erase all your WiFi networks.
Restart your phone to apply changes.
After the rebooot you can set the WiFi again or leave till the end. So, here are the final steps to avoid battery drain.
Go to Settings/WiFi and touch the three dots (upper right corner)
Select "advanced settings"
Open Wi-Fi on during sleep and select "Never"
Open Wi-Fi frecuency and select "2.4GHz Only"
Exit Wi-Fi settings and return to the main screen of "Settings"
Go to Settings/Location
Open Location Mode and select "Device Only"
Touch the three dots upper right corner and enter, there is only one option.
Disable both options "Wi-Fi and bluetooth search".
After serveral tries this is what worked for me, even you can use "Smart lock" and all the apps that use location services, like maps, are working perfectly and in my battery stats the Wi-Fi disappear at all, not even the last.
Please, comment your battery stats and possible solutions.

PS. You will notice the difference after a full charge.

Just followed your step by step, I'll keep an eye on the wifi and will return with the results, but thanks in advance!

I just ran through this on my XT1635-02 Z Play. I'll report back in a few days if my massive wifi power drain is resolved.

A little more than 24h after following the procedure I'll have to say that did the trick:
The Wi-Fi wasn't turned off, but by the chart above, as soon as the phone went into deep sleep mode, the wifi was shut down (as expected when doze mode kicks in). The phone was fully charged 6am today and it's battery has been holding pretty well. It's almost the end of the day and it still got 89% of juice left, with over an hour of SOT and with 3 days battery readings, something I've never seen since I first turned on this phone. (it is in airplane mode not to save battery, but because my room has pretty bad reception, and as long as I practically receive NO phonecalls, there's no point keeping the reception on, it will only drain more battery over nothing)
I've seen a link around here in the forum explaining this wifi battery drainage is a Marshmallow algorithm error, since it's impossible the Wifi alone consumes more battery than the Screen, something considered impossible by the article. Here's the link: http://androiding.how/how-to-fix-wifi-battery-drain-on-marshmallow/
I don't know if this procedes, but my battery readings improved susbtantially since I followed your tips =)
Thanks a lot once again mate! :highfive:

I read the same, is a bug at the algorithm of MM, but, I felt that the WiFi was draining a lot more battery than supposed to do. Since I did this my battery was really improved and the WiFi is not more and issue. Glad it helped you my friend. Regards!

Two screen shots attached. Only 28 minutes SoT since removing from the charger 12ish hours ago.
I'm not sure if it worked or not. As you can see, despite my wifi being disabled the entire day, the wifi was active 100% of the time. HOWEVER wifi power usage doesn't even register on my battery usage screen. My biggest power hog is poor cell reception due to the concrete bunker I work in. My battery usage is much better than last week, and I'll easily get 2 days out of this charge.
Did it work for me? Maybe?

You seem to have a lot of wake locks. That probably doesn't help your battery along with the very poor signal.

I do have an Android Wear watch. That may be some of my wake locks.

I don't know why your Wi-Fi doesn't turn off. As you can see mine goes off sometimes. But as I can see it worked for you despite the poor signal (mine is poor too) and I get almost 4 SOT everyday. You can check with wakelock detector what is wakening your phone so bad, you don't need root anymore to use it.

Will try this for sure. I had tried something similar but turning the Wi-Fi on during sleep to "Never" resulted in me not getting any notifications (whatsapp, emails, etc) during sleep (cellular data is turned off). Do you guys still get notifications when the phone is in sleep?

Moto z droid wife
I did all that but is still not working
My wifi, Bluetooth and hotspot are disabled
Battery drains faster
I'm kind of bored with the phone
Any update to fix that...?

Does this fix work with Nougat? I don't seem to find the WiFi frequency option anymore.
I am only noticing battery drain when the WiFi is ON (even if I set it to never be ON when in sleep mode).
I also noticed the CPU only stays in deep sleep for 50% of the time, and 50% is running at 652MHz.
As soon as I turn WiFi off manually, CPU stays in deep sleep when screen off.

Thanks! This is a great one!

"Android OS" near 90% battery usage (Many screenshots) Please help

Hey guys,
I am having a huge battery issues. I am using Slim Bean ROM right now with Yank kernel, however before this I used a newer version of Jellybean CM10.1 and the problem was the same. Before going Jellybean, on ICS, the problem was not there however.
So when WiFi is turned on, "Android OS" eats a huge chunk of battery when the phone is sleeping. It does not always do this, however. Sometimes the battery curve falls slowly, which I would consider "normal" and the same way it was as I knew it f rom ICS. Then randomly during other times, usually after using the phone and doing something with it, the battery curve will suddenly drop drastically even though nothing changed. I'm gonna post some battery screenshots with explanations. I'd be very grateful if someone could take a look and try to see what's wrong.

}
As you can see here, Android OS takes up the hugest chunk of battery.
The CPU usage and keep awake time is extreme, especially considering how it used to be before that (comparison pics from other ROM are at the end of post).
The screen is barely accounted for any battery usage with as little as 3%
BBS says this:
No idea what any of that means, but I do know that the problem is with WiFi. If I turn it off my battery lasts forever. I even tried using Juice Defender for a little while to only periodically turn on my WiFi every 30 minutes, and it did solve the problem, however I can not keep using Juice Defender as it will always automatically turn off WiFi when the screen goes off, and that is troublesome when I am making calls on Skype or Google Talk. Wakeups which I do not know what they mean, at least the top ones. Seems to be something about the Android OS itself.
And here is a recent picture after again charging to full, where you can clearly see that the problem persists. The slowly falling curve in between the two steep curves is how I expect it to be. However I do not know why the curves suddenly become steep, after pressing the power button to do little things such as checking the time on the lockscreen. I mean it's normal that once I turn the phone on the curve will go down because the screen is on, but I turn it back off right after, yet the curve keeps falling as if I was keeping my phone turned on. Please note that all this time my phone is being in sleep mode 95% of the time, it is not being moved out of WiFi range or anything, it ist just laying there and doing nothing, other than I turn on the screen every now and then to check notifications, not very often though, which seems to trigger the problem. I also made sure nothing is running in the background by long pressing home button and ending everything. The problem whether the sleep-curve with WiFi falls "normally" or "broken" seems to be completely random.
Also last but not least, I will post screenshots of the ROM I used before, CM10 ICS, where the difference is clearly to be seen. This is how I want it to be again but I don't know how.
Here you can clearly see how Android OS uses WAY less CPU and keeps the phone awake for only a fraction of what it is above, even though the way I use it is exactly the same. WiFi running 100% of the phone uptime, with minor usage, and the screen for majority of battery usage just as it's supposed to be. Yes the total phone life is about the same, however the big difference is that as you can see on the last pic I got 3h30 screen on time so basically triple as much as with the problematic battery curve.
I'm really clueless here, I have done several reflashes of Slim Bean and updated the Yank kernel, I also used the official Slim Bean kernel before Yank that still had the exact same problem. I really don't know what causes this other than it somehow has to do with WiFi and Android OS. My only guess is that Jelly Bean works differently with WiFi but it still shouldn't be this extreme as far as I know.
Any help is greatly appreciated. Thanks guys.
EDIT: Problem is fixed, see following post for solution: http://forum.xda-developers.com/showpost.php?p=37987244&postcount=8
first of all may of the photos are unavailable.
the ones that are available looking pretty good over 36 hours working with 3.5 hour of screen on.
as for the wifi you can limit it to work while "sleep" only when connected to charger via advanced under wifi settings.
Ugh, I hate Dropbox. The pics worked for a while but something is weird. I'll upload to another host and edit. The thing is I don't consider it a good running time since the phone is in deep sleep all the time, if I'd use it normally it would probably be dead after like half a day. The one with 36 hours with 3h30 screen on was the one before the problem occured, so yes I agree that's a great battery curve however it is not like that anymore sadly.
Pictures are now working, sorry for that. Any help is really appreciated. I want my old awesome battery curve back! :crying:
Come on guys can't anyone help? Do I really have to go back to an old ROM to fix this? Are there any settings in routers that could cause this?
You are confused, as in not understanding what the "Android OS" usage means. It is the percentage of battery used, not battery use. Since you did virtually nothing with your phone, it is the highest percentage of that "nothing".
Perhaps you should research more...? and actually use your phone as intended and let everything settle.
By the way, it is difficult to follow the various screenshots and deduce what you are trying to show, so some or all of the above comes with a caveat.
sorry for not replying threads get down quickly.
anyways @LenAsh gave you the answer that probably i would give you after seeing the correct pic's.
BTW, i suggest for next time to reduce the pic resolution or attach it or link to it cause it makes your post uneasy to read.

Did you not see the curve? Regardless if I use the phone or not, Android OS should not have such a high battery consumption and CPU/wake hours. It is broken. There is no need to brush the problem off as "nothing" if you looked at the curves you can see that there is a problem because the curve does not drop steadily. If I barely use the phone, screen on should have the majority percentage of the battery consumption.
Anyways, after two weeks I think I have finally found the solution.
To sum it up:
Symptoms:
- WiFi keeps the CPU working and the phone awake
- This is shown through high "Android OS" battery usage percentage
- It is also shown through BBS with wlan_rx_wake being on the top
- The CPU will work at 200MHz most of the time when you turned it off, instead of being in deep sleep as it's supposed to
- Your battery curve will not fall steadily, the problem can be triggered randomly by itself, or not appear at all for a while
- This seems to be a problem within the Android operating system itself, not with the routers, because using a Windows Mobile or iPhone on the same network/router does not have the same problems
Problem: depending on your router, the Android OS can bug up and keep sending queries because of DHCP. This prevents the phone from going to sleep properly when WiFi is on, and causes extremely high CPU usage and wake times when the phone is supposed to be in deep sleep.
Solution: If you have a router that allows for it, give your phone a static IP while allowing the DHCP server to automatically assign IPs to the rest of your hardware (Asus N56U allows for this, for example). If your router can't do DHCP and allowing statics at the same time separately, the only solution is to turn off DHCP completely and assign IPs manually to all of your devices. If you are connecting to a network that is not your home network, and you have no control over the router/hardware, you can't do anything about it unfortunately.
I think this problem and solution should be added to a stickied FAQ somewhere, because I can tell from personal experience that it's extremely hard to analyze the problem and then google for a solution. There are many threads about it all over the internet on several forums without a solid conclusion, they just get buried. Most advice doesn't help and will just waste a users time such as "reinstall ROM" or "turn off your WiFi".
I'll edit the original post and resize the pictures. I hope this thread now has enough keyboards for google searching, maybe other people who have the same problem will find this thread and the solution easier and it will save them the hassle of wasting hours to find a solution like I did.
Thanks for the help guys.
Original post is updated, this will be the last bump of myself in the thread (unless other people have questions and I can try to help). Hopefully this can be used as a source for other people having the same problem.
Cheers guys! :good:

Thank you so much for your time and effort!
My phone was getting very hot and the battery life fell to 6 hours for me all of the sudden. Switching to airplane mode solved the heating and battery usage and that info pushed me in the right direction for finding the solution - your post.
bah I never saw this thread first time round. I could have given the same answer about static IP addresses without all the delays. Sorry.

Same Issue... 90% Andorid OS... i provide a picture from wakelock... can u help me out pls ?
The truth is, that this problem never goes away, once youve got it. I had it from almost the very beginning on my N7 and I tried literally everything, including this method here - nothing helped...I never really believed in this method,tho, cause the problem occurs with WiFi off, too. I dont know what causes this f*ing bug, but everyone who has it, just has to learn to live with it, or buy a new device.

[Q] Deep sleep not deep enough?

I have i9205 for 1.5 week. I rooted it after a few hours I have it. I was in rooted + official rom for a week. Then I flashed Cassies XtraLiteROM to it a few days ago. XtraLiteROM is based on official stripped down to minimum plus some tweaks.
My observation of battery drop during the night (wifi/3g/gps/bluetooth all off) is indistinguishable between the official rom and XtraLiteROM. About 10%-12% drop during the 8-hour sleep.
I greenified facebook app and a few others that I think works in the background. I tried to invoke Wakelock detector, hoping to find something. It appeared normal and said 8-hour deep sleep. The battery level falls continuously and smoothly during the sleep with hardly any wakeup.
Is it common with 4.2.2? I have another LG L9 rooted with 4.1.2. The drop during the night is 1%-2%.
I left my mega all stock. No root or any modifications and when i go to bed i put it in flightmode and it loses about 1% or 2% in those 8 hours just like your LG

I'm also having the same battery drain problems since the first day I bought Mega 6.3. I have tried different ROM versions UAMEA,ED,F2,G3 and now the latest G4 but still having the same problem. Today I lost 3% in a matter of 1.5hours without even doing anything on my phone within those times. Flightmode technique you mentioned seems to be good but the problem is we may not be able to receive emergency or urgent calls/text while asleep. I was hoping samsung would address this drain bug.

But the problem seems to be present even if you don't install anything else than what is supplied !!
I don't understand what's going on with the battery:
one day you put the phone in arplane mode and for 10 hours you eat 1% of the battery :good:
The next day without changing anything you eat 10% in the same conditions WTF !!
As far I can see it seems that there is a problem with the release 4.2 (problem also for the Galaxy S4).!!
In another forum i participate, some people had similar issues, they had been harrowed down to some programs they were running. some people had Mega synchronise their photos every time they connected to the internet others had some other crap going on. if it was a firmware issue, everyone would have it. i, for example don't have this problem. you can try to use Disable service program to see which services are active in the background and are eating your battery and stop them carefully.

For example phone in airplane mode everything off (air view, NFC, GPS, synch off etc):
From yesterday 23.00 till morning 09.00 lost 11%
From 09.00 till 14:00 lost 4%
From 14.00 till now (23.00) lost 3%
Without touching the phone !!
Don't tell me me there is not something strange !!

You've got me all wrong. I'm talking about installing stock ROM (latest version) without any modification i.e. root, cwm, etc and no other apps
installed except samsung built-in apps but still battery drains like hell overnight with almost everything turned-off (wifi, bluetooth, gps, rotation sensor, etc.). So your question is a little bit off topic.

No, not really, because the stock rom is full of bloatware from samsung. I've read reports from other people saying that their camera software or galery or something else, don't remember exactly was uploading their photos to their cloud storage whenever they connected to internet. A lot of stuff can be happening in the background in the stock samsung rom because it's got a lot of stuff in it + the default settings alow synch/backup/downloading updates. Install the light custom rom from this forum, that has everything removed and see how it behaves, alternatively you can use other programs (mentioned one above) to see what's active in the memory of your device and find what's eating your battery.

Ok thanks. I will try silentlight tonight. By the way, I received updates of samsung link from playstore these past few hours and among the reason
for update was the battery drain. Also, I'm using an official S View flip cover from samsung. I was wondering whether there is some sort of sensor activated by this flipcase that keeps my mega from deepsleep.

Have a look here, one more idea for you - http://forum.xda-developers.com/showthread.php?p=44428107#post44428107
My battery drain problem appears to be related to "cell standby".
If I charge the phone to battery full, unplug, reboot, screen off, data off and leave it to stand by for a night. "Cell standby" alone takes up most battery usage and battery level drops by ~10%. I can constantly repeat that. I think more users are having a problem with radio.
Reference: http://forum.xda-developers.com/showthread.php?t=2335242
I am trying to disable fast dormancy to see if that helps slow down cell standby drain.
I have to come back @ my comment on the previous page, since today my phone went battery hungry too at night. left it in flight mode during the night as usual but instead of losing 1 or 2% it consumed 12%.
Very strange since the phone should be absolutly doing nothing at all when its locked and in flight mode.
It's not really a problem since im a fairly moderate to light user so i can do 2 days on 1 charge but still.
I also have a strange wake-up problem now, after using the phone a bit and when i press power to lock it, sometimes the screen lights up again after about 5 seconds and goes off again.
I feel worse than it actually is when I feel like robbed 10% of power everyday for no reason. Maybe I was too picky. I have not given up on this. Will continue to look for a solution.
same **** here, today is even worst, 8 hours of phone not doing anything. deep sleeping is at 92% according to BBS, and my battery dropped from 75% to 61%, wonder wat is happening with my phone. damn!
Try this
Sorry. Very bad know English. Solved the problem of the so-

I don't have the battery drain problem but I'll try that. Thanks.

Standby drain

When you sleep, does your phone sleep, or does it stay up all night and crunch 1s and 0s? Rate this thread to express how you deem the speed at which the Samsung Galaxy S7 Edge's battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.
Then, drop a comment if you have anything to add!
sleeps like a baby, 0% drain on 8h sleep.
10% drain for 8 hours (but I had my enabled the "Always On Display" to Show the Time)
2-3% overnight for me. AOD off.
I had been having an issue where mine was never entering deep sleep. I tracked it to two things. Google voice recognition on every screen and auto backup. Once I turned those off, the battery drain seems much improved, although I only made those changes this afternoon.
If you're having issues you might try to identify the wakelock via ADB. Run the below code in a loop and see what pops up. It worked for me.
adb shell dumpsys power | grep -i partial_wake_lock

That being said, I sure miss having root to run BetterBattery Stats. . . . Sigh. . . .
sorry for the stupid question: does S7 Edge enter deep sleep automatically?
I am having a serious battery drain issue in standby. I did just turn off my google voice recognition on every screen (thanks czucker) so I'll see what happens. Im kinda upset with the performance though. I picked up the phone on Tuesday from my local sprint store (pre-ordered and it came in early) so maybe the phone is still learning my usage patterns but still the standby battery drain is concerning...

Maybe I have the same issue. How could you turn the Google voice recognition and the auto backup off?

I fixed standby drain by turning off NFC and set OneDrive to only upload when charging. Donno if thats your problem, but its my best tips since it worked for me

You will find voice recognition in the Google app under settings/voice/OK Google. The second one is in settings/backup and reset under samsung account.
In my first full day with the S7 Edge I was not super impressed with the battery. From 7am to 9pm, from a full charge I ended the day around 10% with very minimal. Maybe the large screen takes up more juice than I thought---I was expecting the larger battery to last me quite a bit longer. Coming from the HTC M9 and that battery ended my day around 30%.

Thank you! After a few days usage, still not getting good battery life, usage time is around 11-12 hrs, the battery drain appears to be android system. I've turned off almost all apps from notifications and auto updates. Reading other posts the exynos version is getting great life. The 820 and Android system aren't playing nice...
drained overnight
I fully charged the phone 100% before bed. Next morning, 8 hours later battery down to 12 % with android and screen sharing the usage. Next day I resetted the phone to uninstall all my apps and tried again - still almost same result. Is there anything I can do to investigate this? I have turned off Google Voice and Automatic Backups already - the huge battery is performing worse than the htc one m7 i replaced
Any suggestions?
Edit: Should have mentioned - the phone gets untouchable by morning! hot as anything - i guess i should be contacting Samsung

No suggestion. It is best to contact Samsung, as this behavior is not normal. These phones are made to be used, and not for us to turn off almost everything just to get through a day.

Thanks for the ADB command. I'm showing "AlpmModeManager" as a "Doze_Wake_Lock" (I modified the grep string a bit because partial wasn't giving any hits)... Any idea what that is?
Guess when I tuned off the AOD xD

All apps that are part of android system report this percentage.
Had an issue with the "Pocket" app. This awful crap drained almost 10% of my battery and I did not even used it (I did not setup the app and did not opened it.. not even once..). All good after I uninstalled it.

Battery life

Any ideas how to extend the battery life? Hardly used the phone today as you can see from the screen shot and currently on 26%
Not going to make the whole day at this rate

It's a fresh install the other day, I've even disabled the finger print scanner
Sent from my P9000 using Tapatalk
Hi, I'm also using the P9000 for 5 days now.
The battery in standby is ok, but drains quickly when display on.
In my battery statistics, there is no Google Services listed, maybe an update can help you (and also deactivate bluetooth).
I have seen the threads about Eragon custom rom and Rodriguez Mod. Can anyone give further information (maybe some statistics) about the battery life compared to stock P9000_Android 6.0_20160419 ?
Best regards,
miliob

I've heard battery life is better with wifi turned to always on and if you turn intelligent power saving to off. Also search for wifi scanning in settings and make sure those are turned off. I keep my brightness set to under 25% also. Easily get a day. I'd loose on average 1-2% on 4G standby. Agreed though as soon as I start to use something more intensive such as Clash of Clans or watch a video where screen is on for period of time battery drains but then how quickly this phone charges up it isn't as bad as it would have been with a slower charging phone.
Increased life with RoDrIgUeZsTyLe MODPACK 1.1
In regards to your question regarding mods,
I was getting about 8-10 Hours battery life out of the stock firmware with my usage. I have since flashed "RoDrIgUeZsTyLe | MODPACK 1.1" which has upped my battery life to about 14-16 hours.
Hope this helps,
-Harry

If you click the magnifying glass in the top right corner within settings and type scanning you should be able to find it. Intelligent battery save is a switch within battery

Guys... Wonder if you guys may have an idea what is causing this. I still have the FP scanner taking 15- 20 seconds from acceptance to unlock the phone. The power button also is unresponsive..Sometimes requiring a hold down of the power button to wake. It's as frustrating as hell.
Anyways.. Playing around with settings.. If I go back into WiFi -->advanced--> keep WiFi on during sleep and change back to never (going against what
was said previously to extend battery life) my FP unlock issue disappears. The phone unlocks instantly.
What would be causing this, is anyone else experiencing this issue, is there a work around or is it a fault with this particular phone.

That's not normal. I'd try backing up your stuff and doing a factory reset. Have no issues with regards to the FP unlocking.

This issue exists after a factory reset.and only exists when WiFi is set to always on screen lock and phone is unplugged. This may be another clue. Plugged in.. FP scanner works a charm...

I was able to replicate your problem on my sisters P9000. Very frustrating. Out of the three I've bought (two for sisters one for myself) only one seems to be giving problems. Defo QA isn't up to scratch with some of these handsets.

On every rom (even stock ROM) the standby time counts up, If I charge the phone to 100% and leave it disconnected from the charger through the night, it says I have 6 days standby time left the next morning. When I'm using the phone allot, this time is reduced to 4-5 hours.
I don't really know what your problem could be. Maybe an app is keeping your phone awake ( a.k.a wakelocks)? Maybe your battery is defective?
Fingerprint scanner drains almost 20% overnight, disable it

Cell Standby battery drain, please contribute :D

Hey guys,
So apparently the cell standby on my 9t + eu stable rom device is also high, like some of other xiaomi device users. Its about the same percentage as the screen usage, which is a bit rediculous to me.
I have tried switching to LTE/WCDMA, but that did not seem to help.
I am trying some other settings such as disabling Smart wifi/Mobile data switching, disable AGPS , disable bluetooth such to see the effect. Since nobody is siue about the real cause, lets just try with everything that is even slightly related to mobile radio.
So if you would like to contribute, please provide the following information:
- Do you have outstanding "cell standby" drain while mobile data is enabled?
- During all this time on battery, on you on wifi?( i.e. not using mobile data theoretically)
- is your bluetooth enabled and connected to something.
- Smart wifi/Mobile data switching enabled?
- Network type? ( in *#*#4636#*#* menu)
- AGPS enabled?
- Your region, Mobile service provider/company, and if the mi 9t is missing any lte band with your provider?
- **** Add any info you think can be useful. ****
Lets crowd source the problem and hopefully we can either solve it, or find the cause to the problem and tell Xiaomi so that they can fix it...
Also posted on miui EU forum for hopefully more input
So for me,
- i have high drain from cell standby during the day.
- Wifi is enabled, which theoretically should require much less cell data transmission.
-bluetooth enabled and connected to mi band 4
- smart wifi switching disabled
- lte/wcdma, and slot 2 disabled
-agps disabled
- Canada, rogers, and missing band 18 and 26, i think
I have big standby cell drain (same as screen) BUT...
I decided to check drains last week, my test consisted to close everything and go to sleep (8 hours stand by)
- WiFi enabled and data off (LTE/WCDMA singal): 2% drain.
- WiFi enabled and data off (LTE/ TDSCA/UMS singal): 4% drain. Airplane mode and WiFi enbaled: 2-1%
So for me I think it's just a visual bug. Not real life usage actually, so I have no problem if the battery states that.
Region Mexico, ATT, GPS disabled always
Hope this helps

I left my phone yesterday before sleep with 23% of battery and I put 3 alarms that was about 3 am i woke up at 9:30am (yeah after the 3 alarms lol) and the battery was at 21% so i would consider tha the phone doesn;t drain that much on stand by

hummm..i though cell standby drain would only occur if mobile data is enabled, no matter the state of wifi. If data is off then the phone is not communicating with the towers then it shouldn't be using much battery.
And your battery stats seem to confirm this.

so definitely the mobile signal lol At about 1%/hour.
With other phones this may be acceptable but the 9t has a 4000mha battery lol seems the percentage consumption can be lower

I am also in Toronto (Telus). Got the Mi9t about 1.5 weeks ago. My discharge rate with screen off is also about 1%/hour (measured with AccuBattery). I am running stock on latest global rom. The cell standby drain looks like a misnomer to me or possibly combines multiple services behind the scenes. My overall battery life has been excellent, easily going 1.5 days between charges.
Hi, I have a problem with my Mi9t.
I've noticed that my phone is always active, even at night when I'm not using it. The only app that I've blocked from stopping is blokada, because I've noticed that If i kill it in the Miui task manager it kills it completely and I have to restart it every time. I can't find in the battery settings a particular app that consume so much battery. I've also GPS disabled and my Bluetooth is always active for my miband (but Bluetooth voice in battery usage is not that big...) hi
Any idea?

I will, nonetheless I have this situation even when I'm at the end of my battery life. the "active" voice in the diagram is always active, even when I'm not using my phone
I'm debugging this problem too. it appears to happen only when connected to wifi. i've disabled VoLTE and so far i tried LTE/UMTS (prl); LTE/TD-SCDMA/UMTS and LTE/WCDMA. they appear to be all the same.
the fact the it only happens on WiFi means that there's something wrong with the GSM mode (because radio switches to 2G when connected to wifi). I'll try next "Mobile data always active" in developer options, that will keep WiFi and 4G on all the time. we'll see how it goes.
also it could be only a report bug on the battery stats. i keep getting ~9h SOT with this so.......
9 hour of screen? Do you have a nuclear battery?
Usually I use more 4g than WiFi, WiFi works better only at home. Btw I charged the phone this morning, 100% full, now I'm at 62 after 12 hours, but only with a 1 hour and half of screen time....
I have a push mail for work and some WhatsApp message, but nothing else....
