Battery Drain Android One Pie, mobile network standby - Xiaomi Mi A2 / 6X Questions & Answers

Hello, I am new here and couldn't find anything similar in the Mi A2 forum about this battery drain in Android Pie 9.0.
I bought the Mi A2 128gb/6gb two months ago, and since yesterday I realised an abnormal battery drain. When I went to check it out, 37% of the battery was spent in the mobile network standby. Today, after 3 hours of use is around 15% already. In my use, I get between 3 to 5% per hour, now it is between 6 to 10% due to this issue, is infuriating for a phone bought two months ago.
I've been since yesterday trying to find a way to discover the cause, I use 4g LTE most part of my day and the signal is good, urban area, in both sim cards.
Haven't used any custom rom or anything, still standard from the global version, did all the updates, including the latest February 25th. I don't think the update is responsible for that, but it is the only different thing I've done in the last weeks.
Have tried several solutions suggested for others xiaomi models but nothing seemed to work.
Did anyone experience this? Does anyone have a solution?

Yes that is pretty strange. Mobile network standby shouldn't be using up that much battery. Try rebooting the phone to see if it resolves. You could install 3rd party apps such as Greenify to monitor background apps more closely/hibernate them, and Naptime which uses aggressive doze to make sure you get better standby battery life.

Download cpu spy and check if phone enter deep sleep, there was a bug some time before with the cpu stuck at 1401mhz.

Thanks for your answer. haven't tried yet rebooting the phone, I did just the network reset and haven't changed a thing.
I downloaded greenify, but haven't quite used because I can't identify an specific app that is causing the problem.
I am using Greenify, Accubattery GSM Battery, CPU Spy as well.
A strange thing is that the excessive battery drain is allocated in some apps.
Usually, in the android battery use, it shows whatsapp and/or instagram are using the most battery, but when you ask the full device, is when it shows the mobile network.
In the GSM Battery, it says the battery used 12% while turned off and 5% while turned on. It makes no sense.
The only thing I could realize is that when it does get in sleep mode, the battery drain stops, but as soon I start to use it again, it returns to happen. I am afraid is a hardware problem.

Thanks for your answer. I downloaded and monitored for today, most of the time it stays in 633MHz, and Deep Sleep. Both together are above 70%.
I don't think is a CPU problem. I am afraid is something with the antenna

I have an update.
I usually use LTE Network most of my day, today I managed to use wi-fi and the problem is not happening.
I suspecting is either an incompatibility with the Mi A2 network. But my girlfriend has the same phone, but the 64/4gb version and is not experiencing this problem, or and hardware problem with my antenna.
Nobody else has experienced this?

Battery life in the last few days

Anyone notice a change in their battery life in the past few days? My girlfriend and I both are going through our batteries in just over half a day with no use. It's like the phone isn't sleeping. Looking at battery use Display is using all of the battery. I'm running CM7.0.3 and she's on stock. Looking at mine right now the phone has been on battery for 1 hour 34 minutes, and Display is taking 57% of the battery and I'm down to 84% battery.
Yes! I've had my N1 since January 2010. I stayed stock until recently when I installed CM 7.1 RC1 shortly after it was released. Battery life had always been great, both stock and under CM7, especially with SS4N1. Then, a few days ago it just fell off a cliff. I now get only about 7-8 hours, even with little to no usage. Before I'd barely lose anything if the phone wasn't being used (a percent every couple hours).
Now the Nexus One Battery Calibrator application shows a drain of ~200 mA or more constantly.
I've been tearing my hair out for the last few days, uninstalling apps right and left, trying in vain to figure out what's causing this. I even considered a full wipe and reinstall of CM 7, thinking that some system setting somewhere had gotten horked.
I've always had WiFi set to never sleep, since I'm usually either at work or home. I've also had preferred network type (*#*#4636#*#* -> Phone Info) set to "GSM auto (PRL)" for months.
I've not made any other changes I can think of that would've had such a drastic impact on power consumption. I didn't track all the app updates that happened around the time it started, so I suppose it could be one of those. But I've uninstalled just about everything and it's still happening.
I have the same issue! Just in the past week or so. I have about 50% battery then a hour or so later it's dead! I was going to get a new battery today but maybe it's a CM7 issue. I use the nightly as soon as they hit the mirror.
An update on this... There may be a big issue going on with T-Mobile or some recent update:
http://www.tmonews.com/2011/07/t-mobile-g2-users-suddenly-suffering-from-huge-battery-loss/
Looks like other users on different phones have the same issue!
Thanks for that article, Lost Dog. Makes me feel a bit better. At least I know I'm not just going nuts.
My phone still has increased battery drain even if I put it in airplane mode though. It helps, but it's still much faster than before. This makes me really puzzled as to what the cause could be. How could the cell network still be causing increased drain if the phone's completely disconnected from it? Some sort of configuration information it received that persists even after the cell radio is turned off? EDIT: I may be wrong on this one, see below.
Last night I tried a complete wipe (using Temasek's full format "Format-signed.zip" first), and re-installed CM7.1 RC1 completely fresh. I installed only the minimal Google applications and a couple crucial tools (my password safe app). However, I'm still getting the same quick battery drain today.
I hope we (or T-Moblie) can figure out how to fix this. It really cripples my phone as a useful tool to have such short life!
EDIT: I'm going to try a workaround I've seen mentioned in comments on the TMoNews and Phandroid articles about this: limiting the cellular connection to 2G/EDGE only. It seems to have made a significant difference so far. I may have been incorrect then about airplane mode not having an impact. I'd only been checking current drain with the N1 Battery Calibrator app, and never left it in airplane mode for long. Anyway, I'll post back later this afternoon with results.
Ok, so switching to 2G-only for the cellular connection seems to have made a HUGE difference. The drain rate seems to be back at around what I'd expect. Everything else I left exactly the same (WiFi on, GPS enabled, same applications, etc.)
So, I'm starting to suspect something may be up with T-Mobile's 3G/3G+ service in some areas that's preventing phones from idling properly.
Anyone else want to give it a try?
Interesting, I'll switch over to 2G only and see how that affects my phone.
I've gone as far as wiping everything and that didn't help so if it really is a t-mobile issue then that would shed some light on the situation.
I see the same trend when switching to 2G only. Very steep power usage with 3G then a dramatic decrease in the discharge slope in 2G.
T-Mobile has an issue. The trick will be getting someone there to listen.
Sent from my Nexus One using XDA App
Here is my screenshot. You can clearly see when I turned on 3G. Dramatic difference. Looking on the T-Mobile forum there are many people seeing the same issue but there's mostly finger pointing and speculation as to the cause.

I also got the same rapid battery drain since last Wednesday. At that time, I thought there may be a hardware/battery issue for my nexus one. To test this, I switched my rom from CM7 back to GB stock. After a few updates for the GB stock and used it for a day, same battery drain happened. So, I changed to use another backup battery yesterday. It did not help also. I thought it may be a real hardware issue.
Then, I found this thread and research a bit in the web. I found out it could be either caused by tmobile or google map updates. I first uninstall google map and reinstall the new version right from the market again. I also switch off 3G as well. No rapid battery drain for the entire day. The battery runs normally. When I came back home today, I turned on 3G, let it for a couple of hours, checked a couple of emails and received a 20min phone call. Everything seems to work fine. No noticeable rapid battery drain was observed. My conclusion so far is: this is caused by google map 5.8 update.
Try to uninstall it and reinstall the google map from the market to see if it helps.
Good luck.

Well, I'm willing to give it a try, but I'm skeptical. If it were the Maps 5.8 application that was preventing the phone from idling correctly, or transmitting tons of data, wouldn't we expect it to happen regardless of whether the phone was using the 2G or 3G radio connection? Sure, there might be a slight difference in the drain rate, but we'd still expect to see it in both cases. And yet the accelerated drain is alleviated completely by using only 2G. I have the Maps 5.8 application and can fix the problem by using 2G only. That indicates to me it's not an issue with the application.
I'll try uninstalling Maps tomorrow (I'm using CyanogenMod, so it's possible to remove it completely). Then I'll put the phone back on 3G and report back on what happens.
I've been experiencing similar battery issues the past week or so too. It looks like turning on 2G only seems to fix it, but what I don't get is why I'm still getting horrible battery life?
I have tasker auto turn off my 3G all together whenever my screen is turned off, and yet I leave my phone on my desk untouched all day and I end up at 40% when I get off work.
Wouldn't turning off 3G via Tasker be the same (or close to it) as turning on 2G only in the settings?
Hope t-mobile gets this worked out pretty soon!!
Glad I saw this thread. My wife and I both have N1s and have each been noticing unusually fast battery drain just in the last 3-4 days.
Last night I charged both phones to the same percentage, turned off 3G on hers and let them both sleep for a while. The phones are configured pretty similarly (stock, latest Maps installed, similar push settings etc). After about an hour and a half, my phone had lost 11% of its charge and hers had only lost 2%. That's enough of a delta for me to point to the 3G usage as the culprit. I guess I will be leaving my phone on 2G when I'm not using it if I am going to be away from a charger for a while.
It's NOT the Google Maps update.
Well, I did my experiment yesterday to rule out the Google Maps 5.8 update as the cause of this issue.
I'm running CyanogenMod so it's possible for me to uninstall Google Maps completely, not just the updates. I did so on Saturday night. Still set to 2G only, I removed my phone from the charger Sunday morning. A few hours later I enabled 3G. Later that afternoon I turned 3G off again.
I think the screenshot speaks for itself. Again, this is without Google Maps installed at all.
I asked around this weekend, and my friend's wife (also here in Portland, OR) is experiencing the same issue on her G1 on T-Mobile. Reading online I've heard about the problem affecting the MyTouch 3G, the G2, and many here with the Nexus One. The common elements seem to be: T-Mobile 3G service, particular models of phones, and some particular geographic areas.
Bottom line (IMHO): T-Mobile has a problem with the configuration of their 3G service in some areas, and it's preventing many phones from being able to idle/sleep properly, resulting in huge battery drain.
Here's mine, I posted this several days ago in the TMONEWS thread.

That's interesting. Even locking the phone to 2G/EDGE didn't have an impact? (not a Nexus One there it appears, what model?)
How did you go about disabling the 3G connection? I'm not sure if there are multiple ways to do it, but I used:
Settings -> Wireless Networks -> Mobile Networks -> Use only 2G networks
Really strange that even pulling the SIM didn't seem to make a difference. Or maybe that's not the same as turning off the cell radio entirely? Perhaps the issue is lower-level, like the radio constantly polling the tower or something even in the absence of being able to successfully register on the network for active use.
Does enabling airplane mode fix the drain issue for you?

This is a G2.
2G has been much better than 3g, but still probably only 3/4 of my former battery life, optimistically. I checked "Use 2g networks only", same as everyone else. The graph above is a little misleading, since I really saw better battery life, that initial flat and quick drop actually averages out to "decent", rather than "horrific.
At the "Pulled SIM and SD card" mark I re-enabled 3g, so the drain afterwards is still 3g related.
Pulling the SIM doesn't disconnect it from the radio tower, you can still make emergency calls/etc. so it has to maintain a connection I suppose.
Twice I hard-reset the phone, pulled out SD and SIM, and still had huge huge battery drain. Powertutor said IDLE draw was 1437mw on average, no SIM, no WIFI, just sitting there on my desk.
In Airplane mode it'll last for days...

I'm not familiar with Tasker. However, maybe it's just disabling cellular data use, not actually disabling the 3G radio? From what we've seen it appears the problem is very low-level, perhaps something to do with basic communication/negotiation between the cell radio in the phone and the towers, as there's no indication of particular application activity or significant data transmission that the Android OS is aware of.
In the T-Mobile support thread there are reports that T-Mobile is now acknowledging there's an issue with changes to their HSPA+ network in some areas.
I've had 3G off all day and my battery life is back to normal. I'm at 87% after at least 6 hours on battery. Yesterday I was down to less than 50% by this time. Luckily, I am able to be on Wifi at work so I don't have to deal with EDGE speeds, which make the Baby Jesus cry.
deliamber, you probably noticed this already but I'm also in the Portland market. It's gotta be a network issue.
I'm having the same issue on my N1 (I'm around the Portland area myself)
I did everything as well, 2g is the only thing that saves me..
Can't wait for a fix!

20% battery drain over night || FIXED || SEPTERMBER 13 2018

Somewhere earlier this year I started getting a 20% overnight battery drain. On a few nights it didn't drain, but its pretty consistent. I have tried everything listed on this forum..This drain is definitely not caused by any standard settings. I am really hoping somebody with insight into Oreo might have something new I could try. I know xda user Digisteve is going to showup and suggest more things, and that is also not going to work.
Things I've tried.
- using root to disable logd. (saw this as a process in BBS) Still drained.
- Disabling auto-sync of all accounts. Still drained.
- Turning on stamina mode at night. Still drained.
- Removed google play store, google play services framework, and all google aps - and replaced with alternative China app store. - Still drained. Not a play services problem.
- Turning off wifi, all wifi scanning, notifications of wifi networks etc. Still drained.
- Turning off mobile data and wifi - no connectivity at all. Still drained.
- Turned of location in all possible device settings,. Still drained.
- Rooted the device with Janjan method/kernal. Still drained.
- Flashed different regions. Including (Taiwan, my region, Malaysia, Germany, Swiss, HK). Still drained.
- Tried firmware verions , 179 , 205, 235, 270
- Deleting 3rd party apps. Still drained.
- Installing Gsam - checking for consuming apps. No apps listed as cause of the drain.
- Installed greenify. Tried as standard, non-rooted with adb permissions, and fully rooted. Still drained.
- Disabling various packages related to 'carrier services', qualcomm and rcs. Still drained.
- Debloated to the point that the phone had no google apps, no Xperia apps and removed tons of other apps, camera bloat, anon data, etc, all removed. Still drained.
- All built in apps replaced with a 3rd party app, including, sms, contacts, email, keyboard. Still drained.
- Installed Linage OS 15.1 Beta 5. Still drained.
- switched from 3G only to LTE only. both drained equally.. though I have worse single with LTE in my area.
I am hoping there is a better solution than throwing the phone away. Because I am pretty much at that point now. I have spent probably well over 120 hours trying to fix this, and I can't. Its at the point where I need to move on to a new device rather than waste more time.... but there are no small devices on the market now, and also no more classic xperia style devices on the market. Sony does not make the executive, classic 'Xperia' style I fell in love with anymore. I don't do round, heavy, huge phones. Very sad.
UPDATE - AUGUST 14
Now running the latest Customized German 270 firmware.
Still draining 20% per night. Check out the screen shots - clear to see I have almost no apps. No process can be seen as a battery hog in both Gsam and BBS. However Gsam screenshot shows evidence of CPU usage.
UPDATE - SEPTEMBER 13 - FOUND THE PROBLEM
Considering almost nobody had my issue, I assumed my phone must be a dud. Late August I bought a second XZ1 compact. The new phone worked for 1 day, and on the second day drained battery at 15% per night idle drain. Previously I had only tested the sim card by switching 3g,4g and disable mobile data, but never actually removing the sim from the phone. Last 2 nights I replaced my old sim with my gf sim of a different carrier. In the morning I had 99% battery remaining. No Drain!
I then downloaded an app these measures signal strength, and turns out where I sleep at night, there is is less reception. Its not noticeable just looking at the standard signal strength on your home screen, you need to check the more detailed strength in decibel millimps /dbm. I can still get good signal in most areas of my house, but the phone is having to use more power to keep the signal good. I can now reproduce the battery drain on demand. If I sleep with the phone near my bed, I get drain. But if I keep the phone in the living room, no drain. I found that connecting to wifi not a factor, since even if you use wifi for data, the phone was still holding open a connection the the cell tower.
This problem took me months, countless hours, and the expense of buying a completely new phone!!! Now I have 2 XZ1 compacts....arg.... but so happy its solved.
The important point is that if testing sim, good signal, or disabling mobile data, changing 3g 4g isn't enough. Your phone is using more power to maintain good signal.
Thank you to everyone who spend time trying to help me, digestive, proflyer, etc. Thank you guys.
At this point, I think it's highly likely you got yourself a lemon. Since you've already rooted the phone, warranty service is out of the question.
It boils down to two options:
1. Pay for a board replacement.
2. Try your luck with a brand new XZ1C. Buy it online so that you'll get the 7 days return perk (some online stores offer 10 days), keep it wrapped in its original packaging, handle with extreme care, and use it normally for a few days before your return window runs out. If you no longer get drains, congrats, and welcome to the club. If not, accept your fate, return it for a full refund, and give up on the XZ1C - understand that you weren't meant for each other and move on.
I had the same issue. Check this thread. Try that and report back.
https://forum.xda-developers.com/xp...ormal-battery-consumption-wifi-t3740495/page3
I know what you feel. I had this too, but mine went away and I only very rarely have this drain. But mine was always on Wifi. With Wifi off = no drain reported... never.
I investigated it for weeks without coming to a conclusion.
If you can, replace the phone with warranty. Worth a try. Right now in my opinion you have a hardware faulty device.
But i would say to wait for android 9. In my opinion it wont take ages to come. It will much likely come this year.

He still has drain even with WIfi Off, so that not the problem.
The only other thing I could suggest is having the battery replaced at a local repair shop. If you got a lemon battery but an otherwise fine phone, that could help.
How about remove your SIM card with wifi on for over night? Do you still experience the drain?

UPDATE - AUGUST 11
ONE WORK AROUND. If I reboot the phone, then unlock it so "android is starting" screen is complete. Then lock the phone, without doing anything else - The battery does not drain overnight. In light of this, what could be the solution? I know an app sounds logical, but I arlready checking my 3rd party apps, and none of them were the probably, an no battery app has ever listed an app as a drain.
Any technical or Dev person go any idea what that symptom points towards?

This does indeed sound like an app or a service gets stuck in an awkward way. You indicated in your first post that you use better battery stats, do you mind posting screenshots of the top of the summary, kernel wakelocks and partial wakelocks page (showing keeping awake services) as well as the bottom of the cpu states page (showing deep sleep time) "since unplugged" after a few hours of drain?
I have attached corresponding screenshots here for my xz1c (after more than 24 hours unplugged) as a reference (I have play services enabled and syncing both gmail and contacts and so on, no root though).

That doesnt make too much sense. Test it for at least one week before coming to conclusions.
Try this and let me know if it works
I had exactly the same issue
What i did (now magicaly works)
I did not have too many time so what I did was simple and I got a cheap replacement phone in the meantime
It seems to be beyond everything we tried
I conected the phone to the pc and did the fix with xperia companion, then I realized that everything was working as soon as I started to install the apps the problem came back, I installed a launcher (nova) and use it, drained the battery Ăștil reach zero and fully charge it, then everything was working... Back to normal... I don't know how the issue was solved but hope it works for you
Sorry about my bad english xD

The screenshots from BBS look pretty normal, the GSMBattery shots show issues with Google Play Services, so I'm guessing they were taken at different times. But there's nothing jumps out of the stats that looks out of the ordinary. Have you run the phone in safe mode overnight to see if you get the same drain? I think you may just have a duff battery, no one else has reported this sort of power loss before.
$40 down the repair shop to get a new battery is going to be a whole lot cheaper than a new phone.

Thanks didgetsteve. your probably right.... The GSAM and BBS stats were taken right after each other, maybe a gap of 2 mins. Play Services wasnt the issue though, as I tried my phone google free, and it still drained.

I agree with didgesteve, nothing jumps out by just looking at bbs (I am not familiar with gsam, so I cannot comment so much on that).
Before replacing the battery, I would probably make sure that it is not radio/network related. I have noticed that my phone draws significantly different amount of battery (in deep sleep mode) depending on the mobile network. This is mostly independent on whether mobile data is on or off.
Could you turn on airplane mode for an hour or two and verify that it is not the radio chip that is causing your drain? (If that is the cause, I am not sure if you can do anything about it apart from switching carriers or experimenting with 2g/3g/4g settings, but it might be worth knowing)

Before replacing the battery, I would probably make sure that it is not radio/network related. I have noticed that my phone draws significantly different amount of battery (in deep sleep mode) depending on the mobile network. This is mostly independent on whether mobile data is on or off.
Could you turn on airplane mode for an hour or two and verify that it is not the radio chip that is causing your drain? (If that is the cause, I am not sure if you can do anything about it apart from switching carriers or experimenting with 2g/3g/4g settings, but it might be worth knowing)

The screenshots from BBS look pretty normal, the GSMBattery shots show issues with Google Play Services, so I'm guessing they were taken at different times. But there's nothing jumps out of the stats that looks out of the ordinary. Have you run the phone in safe mode overnight to see if you get the same drain? I think you may just have a duff battery, no one else has reported this sort of power loss before.
$40 down the repair shop to get a new battery is going to be a whole lot cheaper than a new phone.
I have read somewhere else that Sony's Home is very thirsty with power, I will give your suggestion a go

I also had the drain that Dean has. But mine wasnt so agressive, I mean, some days it was there draining 30% battery over my sleep time (8hrs) and sometime it just behaved normally draining max 3% over sleep time. But still from time to time the drain come back wich is annoying as I cant let my phone with 30% battery left when im going to sleep, afraid the battery will be dead and the alarm wont wacke me up lol.
On my extensive tests, the drain only happened with wifi, but even deactivating all wifi related process (backups, syncs etc) the drain was sometimes there. Wifi wasnt the culprit with Dean, but on my tests: Wifi On = Sometimes big drain , Wifi Off = never drain.
I never managed to find the culprit of this damn drain and Im a software tester. Gsam did not show anything unusual at all. It was like Deans screenshot.
We discussed about this issue a lot here (https://forum.xda-developers.com/xperia-xz1-compact/help/battery-life-bit-odd-t3688342/page8) but till this day we dont know whats triggering it.
Im curious how the phone will behave on this issue with android P.
@ergoen @Didgesteve . Can you guys comment on my 4th screen shot, the one where you can see the CPU usage. Does anything strike you as odd in that pic? TThe CPU util looks high... it is normal?
i dont see nothing odd there

I'm sorry, but I don't think I have the knowledge to judge that. I would expect CPU usage to be low in deep sleep mode, but since the CPU is mostly sleeping, I guess any requested usage will queue up in a way that might look odd, so what you are seeing might be normal (but again, I don't actually know). I also believe that CPU power consumption is mostly related to the frequency state it is in, so deep sleep should mean low consumption (independent on cpu util %).
As I indicated in my previous post, I would sooner blame the radio chip or the battery than the CPU given your BBS screenshots.
mi drain came back today... some days its there and some days its not...
what a fvcking piece of sh1t is this phone... im done with the all tests. time to try samsung.

Bro, Samsung is even worse when it comes to battery drain. Check out linus tech tips vid from a few days ago https://www.youtube.com/watch?v=n46s_iF_IV4&t=324s
My wifes side of the family all have Samsungs.... they are totally ****. The OS is bloated, ugly, laggy despite monster specs huge ram, snap 845, and battery nightmares on brand new phones exactly like in Linus's video. And there is a stupid "BIXBY BUTTON" on the phone which is a total nightmare. if your with Samsung, BIXBY will the with you, following you forever.
In other news, I replaced my Taiwan XZ1 compact with an Australian XZ1 Compact, and my drain is gone. I drained 2% last night.
There are so many build differences with the Taiwan and Australian build of the phone. Bigger microphone holes, slightly different proximity sensor design, and the plastic back is a rough matt black/gray in the AU versions, the TW version was a smoother shiny midnight black with a silver sparkle in the sun. The biggest difference was of course the battery drain.

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.
https://photos.app.goo.gl/zaAoKBJ4txMa7vRg9
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?
Mi 9T Pro ll Tapatalk
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.

Massive battery drain before and after wipe

Hi. Can someone help me with my problem?
Im facing massive battery drain even after wipe, im only getting around 3/4h SOT. In BBS, 2 alarms are weird Job.delay. And job.deadline. I have wiped my phone, installed last version of rom, after that i have restored my apps. Problem still exist. Next i have installed kirasakura kernel and then frozen every of my apps, and its still there. After night im losing around 10/20% of battery. Im attaching some screens from bbs. Thanks in advance for every help.
i'll try to help as much as i can. install servicely and look at running services. if you see something weird, stop that service.
also, i see you're using bluetooth. that thing drained my battery as bluetooth would stay turned on even when it says it's off. what you can do is turn it on and off and it should stop bluetooth service from running.
in servicely you can disable apps from running in the background. maybe some app is running full throttle even tho you thought you closed it.
another thing you can check is if xmode is running. once i had system turning on xmode on even tho i closed the app that used it.
as you're rooted, check with some kernel manager what cpu governor is turned on. maybe the system is stuck in performance mode.
lastly, you can check your battery capacity. maybe it needs calibration. that could also result in battery drain as it's not charged to the max.
also, android 10 is generaly badly optimised for our phone. it has some good features, but powerwise it's not that efficient.
if nothing works out, i'd suggest returning to latest android 9 and do battery calibration.
Thanks for answer. I have installed servicely but im not see anything suspicious. Xmode is off, governor ist in performance mode. About battery calibration, i dont need extra juice from my battery, i want to lose 1% over night, not 20%.. Probably around July/august everything was fine, my battery last for almost 3 days, now something eating it alive and i dont know what is it. Can i somehow check which app generate this "job" alarms? In BBS its "Android" only..
battery calibration isn't about extra juice, it's about system showing the right percentage. you could lose a lot of battery because it doesn't get charged to its max capacity.
there could also be a problem with the lastest update. when i was seeing a lot of battery drain, i had it because system constantly used location services. check in services if there are any location processes running. also it could be because of network. maybe your phone is constantly switching between 3g and 4g.
you can also check in the kernel manager what is your current battery draw in mAh. if its always over 300mAh, then you have a problem.
look for a wakelocks running in the background and disable and enable some to get them resetted.
Probably u have solved my problem. Even after turning off location, i still have some running services with location in name. I have blocked all of them in servicely and after night i lost 1% of battery. I will check now in later days. Thanks a lot

A reload generally solves nothing and wastes time. It's always best to find the root cause(s) and address them directly otherwise they tend to reoccur.
Viruses (never had to), boot loops (prey it works) and old loads are the only times I reload.

yeah i thought it could be that. it's also worth checking if you have "find my phone" turned on. it's somewhere in the settings. search for device admin apps. if you see any apps turned on as device administrators, turn that off. those could also drain battery
Yep, i have turned off "find my phone" now. Thanks once again. Now i have nearly 8h SoT again. I hope it will be all good now
i'd still do battery calibration if i were you. 8 hours of sot is not that much. i mean, it is if you're playing games all the time
After couple of days, problem is back. No new apps, 3 days was good, 0/1% drain in night, now its again about 15/20%. I will just sell this phone becouse i dont have any more patience...6000mah and my OP3 with half of that value can ez get about 5h sot. Aktually im getting about 3/4h sot and 3h calls. When i have bought this phone i have had about 10 h SOT and 5 h of calls in 3 days of usage. Never again gonna buy phone from asus. Thanks guys for every help
i wouldn't condemn the whole brand because of one phone model.
also try going back to android 9 and check how's the battery drain without any apps installed. then start installing your apps and monitoring if the drain will increase.
i'm currently on android 10 and there is some major problem with battery regulation. raw capacity goes below zero when the percentage is below 10 percent. no wonder the whole system starts stuttering when battery level is below 3%.

Question Battery Calibration on Exynos S21 Ultra

Hi All,
I seem to have issues with my battery calibration. 100-90% is depleted in 30 mins and 10-0% is depleted in 12 mins under regular usage. BBS and Accubattery don't seem to report anything strange. Also, the phone gets extremely hot during these periods. I have tried disabling sync, location. I have also tried enabling power-saving mode but to no avail. Tried with airplane mode on, removed one sim, switched sim cards but to no avail. I also tried running it down to 0% and charging it with three different chargers, Samsung 15w, Mi 18w, and through type c charging with my laptop. The result stays the same. I also forced software recalibration using *#0228#
I have also reset the phone and set it up without smart sync.
The total battery life has been average but not spectacular. I would like to know if there is anything I can do before I claim the warranty as it would take 3-4 days at my nearest service center and I would like to use keep using my phone
Here are a few important specs:
Processor: Exynos
Dual Sims: Jio and Airtel(Indian)
Software version: XXS2AUBB (March Update)
Accounts: 3- Normal, Dual Messenger and Work Profile
Any help would be appreciated. TIA.
What is your total battery time etc

It's likely that Dual sim is the cause for the rapid drain. Did you try running only 1 sim for a day? If the issue persists, then perform an ODIN clean install. If the issue is still there, then send it to service centre
Try wiping phone cache, also instal thermal Guardian from Galaxy labs and see if temps are rly high, if it is try lower the thermal threshold, heat is very bad for batteries so it might be the problem. What are you doing when phone gets hot? I usually get 1 hour SOT from 10%.

The total battery time is 13 ish hours of use with 5.5-6 hours of SOT. I do not have any screenshots but I will try to post them later after today's use.

The battery life per se is not that bad. It is higher than what i have got from my OP8 pro and S10 plus. But my concern is the uneven battery drain. 100-90% is something i can live with. But 10-0% literally is like a new year's countdown..
And my signal strength is always excellent and i have vowifi on. So i thought that shouldn't be a concern.
I am not a very heavy user.. Most of my work is mail, google meet and youtube.

If its just the drain, it should have been fine. It gets ridiculously hot during the drain. There is also an option in Find My mobile to enable sending the location during the last few battery %. Toggling it off didn't help either.

The frame and back of the phone are too hot to touch.. and the screen gets uncomfortably warm. Cpu Monitor hovers around 65 degrees c.
I had an Galaxy s20 FE 5G and now i have S21 ultra and both are draining from 100-90% quickly, I think its the way Samsung is, I guess. I heard this complaint many times and in forums i have read and posted people keep saying its normal for Samsung devices.

Hi..try to do an ODIN reset. That should most likely solve the issue. If you still have the option to return/ replace the device, then that would be a better bet.
24h ago flashed (with Odin) G998BXXU3AUDA ... so far so good . Its too early for conclusions , better battery life is noticeable and no more phone overheating , ... but I will wait for the next few days for a complete conclusion.
One thing to note that if you are using 5G then expect higher battery usage. 5G is data only so a 4G connection is also required for texts and calls, this means when using 5G you actually have to keep two connections to the cell towers. If you have 5G available maybe try turning that off for a day to see what difference it makes.

Please update to the latest version of the update - AUC8 (with the April Patch).
Then, please do a cache wipe.
And wait on a few days for the software to understand and adapt to your usage.
Hopefully things should work out for the better.
