Fix battery drain mobile standby - Xiaomi Mi 8 Guides, News, & Discussion

A troublesome bug that causes the drain (discharge at high speed of the battery) of the MI8 is caused by the voice Mobile standby, in fact if you go in the battery settings, you will notice a high% of consumption of the item in question.
This is caused because, by default in the Xiaomi rom (China or global) is also the search for frequencies also Chinese, this involves an intensive use of the network module that continues in a way to find these Chinese frequencies, which of course in our country , just as all EU countries do not exist, leading to greater use of autonomy.
Xiaomi is already aware of the problem and will certainly be resolved, when it is not known.
In the meantime, you can solve the problem by yourself, as follows:
Enter the following USSD code *#*#4636#*#* in the dialer.
Set the LTE / WCDMA mode to both SIMs
In this way, only the European frequencies will be used, eliminating the battery drain.

You're welcome btw

It's also a pretty old bug, somebody else had the same idea 4 months ago:

When you reboot the phone it returns to the old settings!

Done, let's see now.
Thanks for the info

On miui perfhaps yes.
I'm on Syberia and it stayed like that.
Well, not a big hassle, I mean I reboot my phone once a week.

Come on.. this is not s solution. We have spent a considerable amount of money to buy this beautiful phone. But Xiaomi releases updates with no sufficient testing prior launch and this is actually annoying.

I agree with you, I really do.
But even if you searched about the device you want to buy even for months before getting it you'll see there is absolutely no device existing without at least 2-3 issues out there.
Even pixels which are what android is and more than that, have problems.
You either bear with it, or stop using smartphones.
And the second option is not a viable choice for me.
P. S. Got a poco before the Mi 8 and refunded it because of the touch lag, I know that Xiaomi doesn't test enough, be it software or hardware.

I really respect what you say and most likely you are right but what now? You see I am using the phone professionally and battery is crucial for me.

Thanks for the advice. There is battery drain with V10.1.2.0. Cell standby. BTW, you can reach the menu by repeatedly tapping on "Internal Storage" in the "My device" settings. There are some "secret" links in settings.

If this bothers you that much then either flash a custom rom on it, or refund/sell the device and get something else, maybe an OP6T.

I ran a little test today to find out if other devices handle it better and it does appear to be so. Mido battery drain with LTE/WCDMA and LTE/TD-SCDMA/UMTS was exactly the same.

But the cell signal history wasn't...
Redmi Note 4X, Xiaomi.eu 9.5, 70km Highway drive with Waze and internet music stream running, fixed display brightness. Same route in both tests, just opposite directions - hence me flipping 2nd signal history in the following screenshot:
I ran a similiar test on my MI 8 a week ago and there were massive differences in battery drain and signal history...like I said I think MI 8 has a baseband issue that somehow can get amplified by the MIUI default network mode setting.

well i seen someone said that global beta 8.12.20 it is way better.anyone tried it around here?i was thinking of trying it myself actually...i think i'll do and came back with some feedback.

idk I've been on global beta since 10.0.3.0 global stable release and I've had all of these issues. It's possible that android 9 adaptive battery feature in beta 8.12.20 helps a bit.
Make sure non interactive scenes are disabled in settings \ battery \ scenes

I have the same problem, my drain was 40% in 8 h in standby mode. I flash my phone to miui 9 and then i update to miui 10 - 10.3.3 global, then i clean al my programs and i don't update sistem apps from Xiaomi. At last i turn off my phone and i charge up to 100%. Now my drain battery per night is 5-6% and last almost 2 days?. Good luck!

suspicious battery drain

I got an S3 a couple of weeks back.
I've noticed that the battery duration is subpar.
I haven't even rooted the device yet and it doesn't seem to be the same for everyone.
On the pic attached you can see that it has been a few hours since disconnected and it has already consumed almost half of the battery.
I wasn't doing much other than about 20 minutes of web surfing, 3 or 4 texts and about 15 of playing music for my car stereo through the aux. Other than that nothing, no pics, no calls, etc.
I'm on 3G (H,H+) all the time. Do you think that's the issue?

Depends. Please use the dialer code *#0011# (or *#*#0011#*#* on AOSP-based ROM's) and check if the RRC-state goes to "IDLE" when your phone has not transferred any data for some time and HSPA is active.
If not, your carrier probably does not disable Fast Dormancy or you have Fast Dormancy disabled for whatever reason.
Please, if rooted, let Better Battery Stats (free APK here in Xda) record the Wakelocks across several hours and make a screenshot of the Kernel wakelocks and Partial wakelocks.
All I can see from your current screenshot is that you're constantly discharging and probably are on an older firmware (Upgrade!) since it doesn't include the Fix for the cosmetic issue causing the Cell standby being battery drain Nr.1
Are you using Apps like Skype or Facebook? Both are known battery drainers.
Have you been in low-signal or no-signal areas?

Thanks a lot for the reply.
I'm in Mexico and we haven't had the update released here. That's why I haven't upgraded yet.
I'd love to go to CM9 but as it stands I don't want to take risks with the modem, the scene is kind of young still.
I'm not using skype or facebook. I do have them installed but I don't have them running. I actually have sync for FB disable.
I'm very willing to uninstall both if you think it will help.
About RRC-State:
If I'm on wifi it says iddel.
The phone seems to go to HSPA only when downloading something and stays on 3G while idle. While on 3G RCC State reads "FACH".
How can I enable fast dormancy?
By the way, since 12 am today, I have downloaded less than 7MB of data from my mobile network. Anything else has been over wifi.

If it doesn't go down to IDLE then fd is confirmed off or not working. However not all providers support it so it's not that easy.
You can try this, but do a backup of the corresponding files first and of course replace wherever required the values with your provider's:

You don't have to wait, just flash any Rom of your liking, including e.g. Omega ROM. You can flash the CSC back.

The problem is, your phone keeps a full-fledged high-speed data connection open at all times since it or the network is unable to go to Fast Dormancy. Open 3G/HSPA connections drain the battery faster than you can look. Talk about carriers sucking you dry =)

The modem doesn't change when flashing CM9. You should flash the BFLB modem though since otherwise you get issues with voice calling.
Plus, you can always go back to stock by flashing your (or a close) firmware from samfirmware.com through Odin.
I highly recommend trying CM9 =)

Thanks a lot for the help. I don't think I have the data required for doing that mod for fast dormancy. Most likely that is the culprit then...
I was waiting to root and such because of the flash counter but I guess there is no point in waiting. The phone like this actually doesn't do much for me. It's a pain to be concerned about enough power and I totally need to have the data on all the time (critical work emails). I always carry a backup iPhone 4 in case I have problems with my main android but I rather just use Android all the time (it rocks!).
I guess I'm down for CM9. Just one more question, my firmware doesn't appear as it is on samfirmware. How can I find out which one is closer to the one I got right now?
Edit:
Actually I found it. It wasn't there before but it is now. It might be newer to what I got right now.
I rooted my device and made a nandroid.
Just for research, instead of putting a new ROM I'll try to do a bbs log of my phone as it is to try to find out the reason for the drain although it might very well be the carrier config.

I'm getting horrible battery life too. I had it fully charged at 100% and it has been on for 2 hours with barely any usage, and now it's at 80%.
I have been running 4.3 a long time now on my One. It takes a couple days to calibrate. I have had the best battery life ever on 4.3. You just ned some patience. I hear it all the time on the 4.3 custom ROM threads.

I was on STOCK 4.3 also WW edition. I just switched to stock T-Mo edition. Search the forums and you will see a bunch of complaints about battery life on 4.3 after just a few hours of flashing. Everyone replies back to give it a few cycles and how it is the best battery life they have ever had.
The battery life on mine with the 4.3 has improved greatly.

I hope it works its self in, because yesterday was HORRIBLE. Even today, I took my phone off the charger 30 minutes ago and with NO USE, I'm at 92%

Guys... Install something like Gsam battery monitor so you came actually tell what is using your battery.
You most likely have rouge apps that are causing wake locks

Anyone else getting sluggish performance after the update? I never had any performance issues on 4.1 but some apps are really slow and jerky now, even some of the regular system animations are slower.
Also, is it just me or did the developer options disappear from settings.

Yeah, I had to Factory Reset twice to get rid of the lag, and it didn't completely resolve it. It's like even some of the core apps aren't optimized. Weird. The stuttering animations really make me pissed
If you want developer options go to settings, about phone, software information, more, then click on Build Number a bunch of times and it re-enables developer options
I feel bad for u guys tht had to wait all this time and now have performance/battery issues ... I have none here hahahaha
Actually I think it's better after that 2nd reset. It may have just needed some time to "settle"

I don't want to factory reset, especially if it doesn't even solve the problem. This is lame.
I disabled the lookout app. That got rid of my wake lock . Battery life is still bad though.

No problem here. I did notice that my phone was running hot after the update. I ended up powering it off for a few minutes. When I powered it back up, it ran at normal temperature. Or maybe it just cooled down.
well, I sure am glad I have a jump from t-mobile. I'm going to offload this piece of crap for Nexus 5.

I have no battery issues here. I cleared all cache using an app right after the update.

KitKat wakelocks issue

Hi guys!
I usually use a 4.3 rom because of this issue but every now and then I feel like flashing a 4.4 rom just to see if it it would go away.
So on every 4.4 rom i used i got crazy 3g related wakelocks. Is anybody experiencing a similar problem? Here is a photo of BBS:

Thanks to it I've got ****ty battery life (14h tops). I have also tried disabling fast dormancy with this i9300 market app, but it didn't seem to help.
Is there anything I can do?
1. How old your battery is?
2. How much battery life you used to get on 4.3 with similar usage?
3. Which kk ROM you have tried?
4. What was the SOT when you took this screenshot?
1. I guess it's maybe 1,5 years old. I don't expect miracles, but battery time now is patethic.
2. I could reach like two times more, 25h from 100% to 0% with 2h SOT.
3. CM11, SlimKat, and now I am using PAC.
4. I don't remember exactly, but 1,5h tops
Hmm.. looking at your information i can pinpoint it to the 3g wakelock only.
I am finding this on github-
svnet-dormancy / multipdp
Author(s): sven, credits to Entropy512 @xda-dev
Ranking: n/a
Speaking Name: svnet-dormancy / multipdp (those are synonyms, depending on android version)
Rationale: svnet-dormancy is a kernel wakelock related to cell data transfers - Fast dormancy or not, you get a 6 second wakelock any time the radio transfers data
Know actions: Change the duration of the wakelock (use at your own risk). Reduce the wakelock by reducing the amount / number of data traffic requests
Known conditions of occurence:
Caused by data traffic
I am unaware of a solution for this. Maybe someone else will be able to throw more light on this. hang in there.
I'm having exactly the same problem as you, those 3 wakelocks(multipdp, secril_fd and l2_hsic) are killing me. I tried to change ROMs, kernels, radios, but couldn't get rid of them.I've done a lot of research, but didn't come up with the solution for this. I even tried with neatrom, jb version, which is closest to stock, and I have those wakelocks there too.
Any luck?
Hi sheo,
Did you found the root of this problem?
I have the same situation, all kitkat roms I've tried so far (including CM, OMNI, SlimKat and lots which I don't remember anymore) have this wakelock problem.
Some users at the better battery status have tried to help me, but all they suggest is to turn my smartphone in a dumbphone by disabling/uninstalling everything that makes sense to have in a smartphone!
So, (sarcasm=ON) without removing, facebook, google play services, google plus, disconnecting from wifi, going to 2G and dimming my display darker than a black hole, (sarcasm=OFF) were you able to use KitKat on your I9100?
Thank you! :fingers-crossed:

I just switched back to stock rom from my carrier (Brazil Vivo), as there is no wakelock but it is killing me with slowdowns, glitches, bugs... And that sense of using a 2011 (amazing) phone!
I'm just preparing to install SlimSaber Reborn and came to this threat to check for some hope.

Extremely mediocre battery life?

Hey everyone,
The battery life on my S9+ seems extremely mediocre. After not even 2 hours of SOT I am left with less then 25% battery. Also, Google seems to be using the most battery.

Is this a recognizable and fixable problem or should I send it back?
Thanks for your help!
That could be due to not-so-optimized software.
My device is still stuck on the January update, so I'd guess that there will be an update soon.
Future updates might very well fix / improve the SoT, so it's basically down to: do you want to wait for updates or are you willing to use custom roms down the line?
If you answered "no" to both, then feel free to return it and get a different device.

You can pretty much be confident it'll be a software issue and nothing to do with hardware. There will be fixes and optimizations coming. Naturally the battery burns down a lot faster in the first few days.

I'm now on 2 percent after 2 hours and 10 minutes SOT. Surely this must be more than unoptimized software? My S8+ lasted way longer and software wise it seems the same.
For me it's decent, this is my first charge (s9+ duos)

That's not normal at all. Do you use the Google app regularly? Perhaps for voice searches or something like that?
I'ts not supposed to drain anywhere near that much.
The March security patch OTA was released for some countries today, check for an update, and after installing it, I'd recommend a factory reset and then start from scratch.

I don’t use the Google App at all I think. I do have Google Assisant and “OK Google” on, but surely that cannot be the cause? I haven’t used it once today.
I’m letting it charge back to 100% after which I will see if there’s an update. If it’s the same thing tommorow, i should probably return it, right?

No, don't return it just yet. This isn't a hardware problem.
Check if there's an update for the Google app, if not, here is the latest stable APK for it:
https://www.apkmirror.com/apk/googl...le-app-7-22-24-21-arm64-android-apk-download/
Once you install this. Clear cache and data for the app, reboot your phone. Charge it fully to 100% and then go about your day and see if the battery life changes.
If it doesn't, give it one last shot by doing a factory reset (and/or updating to the March patch), and then observing battery drain.
If all that fails, then yeah sure, return it.
You have some weird thing going on
As you can see the battery is great it might be that its downloading all of your email attachments you should disable downloading email attachments via wifi on your gmail account. Reset phone and dont install it see how it goes first

https://www.apkmirror.com/apk/googl...le-app-7-22-24-21-arm64-android-apk-download/
Once you install this. Clear cache and data for the app, reboot your phone. Charge it fully to 100% and then go about your day and see if the battery life changes.
If it doesn't, give it one last shot by doing a factory reset (and/or updating to the March patch), and then observing battery drain.
If all that fails, then yeah sure, return it.

I installed the latest Google app using the link you provided and cleared the cache and data. There weren't any software updates available yet, however.
I do have a suspicion. Normally I always set my phone up from scratch but this time I used Samsung Smart Switch to quickly move things over from my S8+. I've got a feeling that this may be the cause but I'm not sure. I'll see how it goes first before I reset my phone.

You have some weird thing going on
As you can see the battery is great it might be that its downloading all of your email attachments you should disable downloading email attachments via wifi on your gmail account. Reset phone and dont install it see how it goes firstView attachment 4442298

I completely disabled Gmail using package disabler since I use Nine for my mail anyway. I'll go another day like this and if it's still this bad, I'm going to reset and setup from scratch. I'll keep you guys posted.
Thanks for the help up until now!
Mine still going strong; January 1 security patch.
But this is with wifi and indoor use, LTE and day light will be another story... And almost no real standby today.

Every android user should know about BBS and should install it on a new phone. I'm on second cycle with my s9+ on LTE only
And wqhd resolution

Sorry but do you mean when you say BBS?

It can take at least several charge/discharge cycles for the metrics related to discharge levels to home in an a reasonably accurate curve, and this also depends on your particular app usage pattern. For now, as the HGTTU says: "Don't Panic!"

Question MIUI 12.5.5.0 battery drain

Hello! I just bought recently this beautifull phone, I adore everything about it, except - the battery. When I 1st turned it on, it found an update 3,2GB and I applied it, 12.5.5.0 Global. I wonder if I did a mistake, maybe MIUI 12 was better.
Batt drain is huge when idle, 10 or more % overnight.
Gsam app (with adb permissions) says screen and system() are the highest per consumption.
Should I install eu rom (which)?
Or maybe the 1st rom for this device V12.0.2.0.RKIMIXM ?
Give it some time to adjust when fresh. Disable auto brightness and read this https://forum.xda-developers.com/t/uninstall-bloatwares-no-root.4321387/

I'm on 12.5.5.0 and have no battery drain in idle.
Maybe you have to do some background settings.
Me neither, no problem. I'm just getting about 8 hrs of sot. Regular use and 60hz

That's amazing, I can't hit 5 hrs with 90hz, android system is draining a bunch of juice in my battery.
Same here. 4.5 hours of SOT over 24 hrs. Android System is the second most user (10%) after Screen (50%). Not sure why Android System is using so much.

10? My is using over 30%, sometimes climbs to 40... it's just insane
Was on 12.5.5 too and didnt think too much of it until I saw this post.
Was getting barely 3.5 hrs ending at around 12%. Running phone at 90hz
Sometimes I would just charge it mid-day to get some juice.
Had a tough time trying to downgrade to 12.0.2 but finally did and battery I think is alot better.

So, yeah... its 12.5.5 that's screwing our batteries up?
Oh I forgot to mention also that I did use xaomiADBFastboot tools to remove the unwanted bloatware like the services and apps. I did this on both firmwares.
While using stock i noticed a few things . Each update was using more battery. Remember two things.. we have a good processer with a medium to small battery in keeping with it's design so we shouldn't expect the same battery life as the other "thick" xiaomi models. Having said that . I flashed a custom rom and without gapps the phone can last 2 days using camera watching videos and with Bluetooth on listening to music .So if you want decent battery. Start by not updating..using miui is like using google x2 ...so xiaomeme and google are sucking juice with processes under "system" and it is also what's causing heating . Apart from not updating, you must debloat and also root to disable certain gapps and xiaomi processes you can't without root. Next you absolutely must go through all the apps permissions and disable auto start and background battery and data for stuff that are not essential when you're not using your phone. THIS SAVES A HUGE AMOUNT ..just killing backgrounding of google application will save you a few percent. So that's all, no secret sauce . Just kill all the unnecessary background data and battery and auto start or disable google gapps and xiaomi stuff you don't use . Obviously you can see from my post that to get great battery you need to run pure aosp or lineage gsi using gapps replacement like nanodroid and fake store . If you don't want to go that far ,use lineage with minimal gapps and tweak the apps permissions and backgrounding . You will solve heating and battery issues. The problem are the gapps and xiaomi applications getting updated with each incremental update. I have tested on benchmark applications that each update is a little lower in points ..not much but a little worse. So be careful of updating. Sometimes xiaomeme is not refining stuff before making changes to new releases. and you need to imagine just the miui theming on top of aosp is already gonna use battery and processor. So that's my experience with the battery.. Obviously our screen at max brightness will kill our small battery quick, so try to be conservative and use autobrightness . You must also select in cellphone network to use 5G battery saving option. So when you don't use the phone it drops to 4G or 3G to save battery cos with each incremental G the network or gsm and sim suck more battery juice .Try to remember how hard people got hit when we went from 3G to 4G. We had to increase battery sizes quick....
use this application with root to get "better battery stats" ...the name says it all
