Battery drain : 4h SOT - Xiaomi Mi A1 Questions & Answers

Hello,
Since a few weeks, my xiaomi a1 can last only 4 h SOT with a 100% battery.
I tried to switch kernel, to switch different roms (RR, AIM, Pixel Experience) and even to downgrade to Android nougat. Between all version switch I wiped ALL the memory...
I even tried to calibrate battery, by a full discharge and full charge, and by the "root method" (https://play.google.com/store/apps/details?id=com.nema.batterycalibration&hl=fr)
I don't have a huge usage of my smartphone, small social networks, music and web browsing. With the same usage I had 8h SOT before.
I don't know what to do... I start to think that my mi a1 has an hardware problem, what do you think ?

A kernel shows its effect after 2-3 cycles . so make sure to stick to a kernel for 2-3 cycles

I had big battery drain on my Stock Mi A1, overnight it was draining 20%. My problem was with WiFi router. Wireless was set to Channel 1, I changed it to Channel 6 and now there is 1-2% overnight drain and I can get 2 days without charging. Check what Channel is set for your WiFi if you're using it, and then set it manually to Channel 6

Can you tell me how to change the channel

I too sometimes get 4 hours of SoT until 30%, other times it does more or less.. so I guess it also depends a lot on how we use our device..

Depends on what router you use. You will need to login to your router, then find wireless settings and there will be Channel option, probably set to Auto, change it manually to channel 6. Find how to do it on Google or YouTube.

Thx to you for your answers.
I tried the customs roms and kernel for at least one week before change...
I know all depends of the usage but here, with the same parameters and usage I went to 8h+ SOT to ~4h, and many wipes and software change have not resolved the issue.
I will try to post you a screenshot nextly

Standby Battery Life is awful! N910C

As the title says, standby battery is awful.
I have all the bloatware disabled, only things on push are gmail and facebook messenger.
Cell standby is also sitting at 20% battery usage, no matter what, 2nd on the list behind screen time. Note 3 had exactly the same issue where cell standby is concerned. None of my other phones have had this issue, including my S2 with buggy as hell CM11, OnePlus One, Moto G LTE, etc.
No matter what I do, even with everything disabled and on airplane mode, there's a constant 1% battery drain every hour.
In my Note 3's case, this only happened on stock samsung firmware. When I flashed CM11, the issue went away completely. Something like 0.3% drained per hour instead.
So to me the issue is with Samsung's crappy software. I know the battery life was woeful on the Note 4 anyway before an update came in to fix things up a bit. Maybe they're saving the fixes for 5.0?
I know a new update for the N910C was released a couple of days ago too, but not available on European models yet.
Anyone else having these issues?
I dont have this issue at all my friend if i were u id try a complete wipe 1st, some people have had this issue too so returning could be an answer
Same here...
I only lost 4% battery overnight and don't have this problem too
20% battery loss on standby but mobile data was enabled.
^ you may have a bad app and/or bad signal
I have 4 bars lte at home, 2-3 bars at work, wifi always full signal at both work and home, one is ac 5ghz, other n 2.4ghz, no difference in drain either way.
Ive done a factory wipe 3 times now, even through recovery once. No change. Better battery stats and gsam both report no rogue apps, and ive also tested by having no apps installed, with and without bloatware disabled.
Im not really keen on the idea of voiding my warranty to test other kernels etc, and the only other option is to flash the ank5 update to test.
Ive attached another screenshot showijg the issue better. The drain gets noticeably worse after the first 50% or so, but that could be caused by many things, like inaccurate readings.
Like i say though, 1 of my 2 note 3s had the same issue. Could well be a faulty wifi/cellular chip.
Ignore the time its been on, the same thing happens during a day of heavy usage when in standby, same level of drain constantly.
1%+ may not seem that much to a lot of people, but with my usage i should get through 2 days regardless. It should be less than half of what it is. From the curent reporting in the battery stats, im losing almost 50% of my battery in standby over a day and a half or so.

Is location / sync off? Those a major battery drain during standby.

The only things enabled for sync right now are the basic google apps such as chrome, calendar etc. They rarely sync though, and no other phone I've used in the last 2 years has had an issue with them.
Samsung sync constantly returns errors so I leave that off.
Last thing I'll be trying tonight is a full wipe without disabling any built in apps. Its doubtful, but maybe one of the core shamsung apps are trying to communicate with a disabled app or something. I really don't know.

Any update?
My n910c is terrible too. 15% battery loss in 3 hours of standby alone! Wtf! Tried every battery saving trick' no location on etc...
i would suggest u do few thing while u get on bed next time,
Full charge your phone and unplug before you on bed,
1. Restart the phone while on charging,after restart go to home screen and lock the screen and unplug then go to sleep,check it at the next morning u wake.
2.Left the phone with your daily apps running,full charge and unplug then go to sleep,check it at the next morning too when u wake.
this is how i solve those apps running not right.
like the screenshot below,
An apps running at night drained 30% battery within 6hours & 30mins & without switch on the screen or touch anything since i'm asleep *with wifi on*
2nd screen shot shown that cm browser running and consume 94% of processing among 30% battery
while cpu only running 20mins since i had weather & sync on during night.
After that i report to cm team and they send me latest version,
after re-install my phone just back to normal.
now my N910c note 4 is consuming 1% every 1.5hours standby with wifi/3g connected *my area 4g only 1~2 bar so i changed to 3G*
average daily usage were 4.5~5.5 hours screen on time with social apps,browsing infomation,checking e-mail every 1or2 hours,reading news with flipboard,news app,drawing something,watch some youtube video & with auto brightness but indoor most of the time.
hope this would help you

I did a full wipe, installed ANK5 update, unplugged at 10pm at 100%, woke up at 7am with 97%. This is what it should ALWAYS be.
However, after the 2nd charge after the full wipe, it's back to what it was, if not worse. Last night I unplugged at 11pm, woke up at 7am with 92% left. That's bang on 1% an hour again.
There is nothing keeping the device awake at all. It's very frustrating.
I can only assume Cell Standby is so high due to the fact that the phone isn't actually doing anything while the screen is off. After a 20hr day with only 1 hour SoT it's sitting at 72% battery left, with cell standby at 31%, just above Device Idle at 29%. It's a mystery to say the least.

Thanks for your post. I'll definitely try restarting etc again beforehand. I'm also considering another wipe, as S-Voice being disabled seems to cause quite a few errors in the camera app. The battery drain increased after I opened the camera app too, even after force closing etc. That could just be coincidence though.
1% every 1.5 hours still seems like a lot to me, but it seems like you have a lot more apps and things running, so it's actually very good!
Very tempted to just root the thing now and throw on a debloated OS and custom kernel.
Last night i go sleep with 10% of battery left, ( im not force closing any application at all - just exit ) when i wake up ( about 7 hours of sleeping ) phone was showing 8%
No data/wifi/gps etc. If you are not using mobile internet, switch to GSM! It takes more than 30% less battery power than 3G
I'm thinking this is a hardware fault of some sort. Maybe battery, I'm gonna replace and see cause tried from full charge placing it in airplane mode to see if signal was causing the problem, didn't touch it, screen off whole time for 2 hours. Upon looking at it I saw I'd lost 7% battery! Omg! In airplane mode?! In 2 hours?! In standby?!!
In normal use there are no Rouge apps or strange readings in battery stats at all. May be hardware fault.
I've had the N910K exynos, 6 hours plus sot battery life
I've had the N910F snapdragon, 6 hours plus sot battery life
This n910c give me 3 hours sot. I'm pissed lol. Right off!!
Thats really weird, it can be issue of the battery. My 910C has about 8/9 hours of SOT ( wifi only ).

Your mobile signal is very poor. I believe you have full bars but your screenshot ... well it shows us that your reception is poor. It may be one of the causes for your fast drain...

My SoT is fine if im only using it during 1 day. Its usually close to 6 hours. But its not heavy usage, just browsing mainly.
Let me know how the battery change goes. Im likely going to order a spare anyway for when im away from home, so will also report back.

At work its pretty poor, usually a bar or two on lte, but no other phone ive had has displayed battery drain like this in standby.
That still doesnt explain why it drains 1%/hr with nothing happening at home though with 4 bar lte and full wifi signal.
Ive also noticed voice calls are taking up significant battery. A 3min call used more battery than 20 mons of screen time at half brightness apparently, unless thats normal.
If its normal, then to me the cause seems to be battery related. If not, then faulty cellular chip.
Also heres some more screenshots.
This is over the course of the day with barely any usage.
The chunks where its awake, that's just when I'm playing music, not a rogue app.
Note the big standby drop at the start, then the standby drop later, both completely different amounts of drainage, yet both when doing nothing.

Marshmallow wifi battery drain bug..

After installing marshmallow to note 4 910F, I found out to much battery consumption.. It was more obvius when i left phone at night, connected with my wifi router. It had 20-30% battery consumption at 7 hours. Phone on, wifi on, rest off.
If i turn off wifi, no battery drain.. I loose 3%.
Even with 4G on, and wifi off, i loose much less!!
I tried more than 4 roms 6.01, factory erased everything, even safe mode. Always wifi drain.
In lolipop i had about 3% drain with the same.
Searching in net, i found out same problems mostly with nexus (probably because they had first of all marshmallow and they find it first..). I also found the same for note 5.
Many say to set router to 2.4 gihahz, set static ip, turn off something like v6 ip protocol? I don't remember well.
Also i read, mostly problem exists if router have huawei chip.
Checked mine, and it did had huawei chip..
Anyway i didn't found a solution for this. Tried better battery stats and found out tha alarms was for long time. Sleep was 85%, when normal would be 97%.
I also have a photo showing bigger drain in wifi than 4G.
Anyway how problem solved? I changed router and with everything same, i loose 3%....
But when i connect to other routers coffe, etc, if they have the same chip i still have drain there.
I probably find out the problem in note 4 first of all, as i dont read anything searching so, i inform others here.
note marshmellow battery drain
hope this helps. had the same problem of battery drain and not being able to put phone in power saving mode. i stumbled upon things that the update cuts on and you have no idea, anyway, it seems that the update has the search for other devices running 24/7 and you have to go in and switch it off. since then power mode has been enabled and stays on and battery life is back.
hello , guys .. beezyb can you explain with steps ?! you said that it seems that the update has the search for other devices running 24 hours / 7 days and i have to go in and switch it off ... bla bla .. what you mean with that ? !! can you help me ? !

A7010 battery drains extremely fast in stand-by

Without touching the phone at all, the battery dropped from 100% to 50% within 24 hours give or take. I tried disabling background apps in the settings yesterday but after 12 hours it's down to 24%. When I look at battery usage, it's 85% CPU, which is odd, since the phone is literally just locked sitting on the table. Wi-Fi is disabled, cellular is disabled. Any idea what may be causing this?
Same problem here

THis may sound insane but you can try.. Factory reset your phone.. Install only necessary apps... Charge your phone between 90-99 don't charge it 100%.. Now check the way you checked last time..
Went through two of those within two weeks, appears to be caused by Marshmallow system update, since the battery was fine when the device was at Lollipop but as soon as the update got installed, it started to drain like crazy. Looked through Lenovo forums, seen multiple complaints about the update causing battery drain, no solution, no system patch so far. Doesn't seem to have a 100% rate of happening though.
Bought a different device in the end.

Will this disable volte?
Hello , All,
This is very common problem with most of the Lenovo OTA update releases. (especially from Build : S219, S230 and S232 .) there will not be any issue if you use any custom roms.
actually CPU deep sleep is not enabled for those builds who consumes more battery.
please flash stable stock builds OR use custom roms, which has more features . (caution: warranty will be gone)
thank you

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 Xiaomi Mi 8'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!
Hi all, i use china rom and i can show you how los is draining when idle( the phone was in my night table) overnight.
I would say there's a 15 -20% drain overnight, I've had my Mi 8 for about a month.
9.5.11.0 Rom

Yeah no problems with drain here either, run xiaomi.eu MIUI 10.
My bootloader is locked. I can't install other roms. My main concern isn't the battery drain however as it charges up so damn fast. I have GPS issues, it's really slow and it constantly gets turned off despite given all permissions for google maps.
3-8% drain over the night
Chinese rom: 9.5.11.0
Hi, I have xiaomi.eu 10.10.18 rom and I have I think serious drain. In GSam it looks like this. Anybody else have that RCS phone app using that much juice?
There's big problem with cell standby brain on this phone!!
yeah, also on xiaomi EU 10.1.2 and got problems with cell standby.... it takes around 21%.....
5-7% overnight on global beta 8.12.20, network mode set to LTE/wcdma and adaptive battery enabled.
Always on display enabled

The cell standby is not a direct reflection of the power drain, it only shows the proportion of battery usage compared to other components. e.g. if you have the screen on for long time, then the cell standby for the same period will be relatively small.
You can check out from my test. My phone can have cell standby of 34%, but the battery only drops less than 2% overnight! I'm on Global Stable v10.1.2.0 through OTA update.
Yes, posting screenshots of your battery usage without mentioning or also posting screen on time is completely useless.
Mobile standby dropped for me with similar or less amount of SOT after switching network mode.
Miui Global 10.1 Stable 10.1.1.0 (PEAMIFI)
Battery lasts more than 3 days with these settings.
If i let wifi on, it drains 15-20% while i sleep.
Preferred network type = 3G
Wifi, bluetooth, gps are off when not in use.
Debloated using MIUI 10 De-bloat (Then i installed Google Phone,Contacts,Messages)
Facebook,youtube,9gag vs.. for these kind of apps, i go to their mobile websites in chrome and use "Add to home screen"
Installed Greenify, i actully dont know if this app makes any difference.
Alot better battery on custom rom
When I was using MIUI 10 Oreo battery was great between 8:30h and 10h SOT then I updated to pie and man what a horrible mistake battery came down to 6:30h 7:30h SOT, now I'm using pixel experience and getting between 8:15 to 9h SOT.
Since Xiaomi isn't responding to the Bug thread on MIUI forums:
https://twitter.com/_Princeps_/status/1082926593331343360
Please retweet this if you have an account so we'll maybe get a fix for all these MI 8 battery issues.
9% drain in 7 hrs by night, 2-day total radio stand-by drain 15%
I get 9% (too much) discharge in 7h by night (wifi and LTE radio on) while I sleep, no display use and most apps shut down, and few wakelocks (0.5% total time). Something's wrong with the radio. I am on LTE/UMTS auto (PRN), 9.1.3 EU, Sphynx kernel. Radio usage is 38%, and Wifi 5%. I get full bars of LTE at 1815MHz band 3 (Net Monster RSSI -59 dBm, RSRP -87dBm). NetGuru reports driver bug and won't start.
When I set Airplane mode or turn off the phone by night discharge is minimal (~3%).
In more than 2 days on battery with intense screen use (14h SOT), total standby-drain is 15% (too much), and display drain is 26%. Wifi and radio was on most of time.
¿What's the conclusion? This phone drains on stand-by. Battery life is good in general, but stand-by should be less than 9% in 7 hours, I'm sorry.
P.D.: I will try Syberia rom, maybe we need updated kernel with better radio drivers...
The conclusion is that the baseband is ****ed.
There's all kinds of weird stuff hapening and it appears that at least one of the issues is that the MI 8 will always follow the MIUI/Android configured network mode instead of the SIM card overriding regional differences.
Lemme copypasta my own post from the MIUI/Xiaomi.eu forums:
My initial tests regarding the Network Mode on the MI 8 are on page 2 of this thread. To narrow this down I ran similar tests on my Redmi Note 4X to find out if other devices handle it better and it does appear to be so.
MIDO battery drain with Network Mode manually set to LTE/WCDMA instead of the MIUI default value of 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 then went and checked what would happen if the network mode was manually set to "TD-SCDMA only"
Mi 8 @ global beta 8.12.20 set to "td-scdma only" : NO CONNECTION!! MI 8 just keeps searching for TD-SCDMA cells and doesn't find any.
Could be another hint that our mi8 is reacting adverse to the lte/td-scdma/umts default setting... the SIM card should override this setting.
Redmi Note 4x @ xiaomi.eu stable 9.5.2.0 set to "td-scdma only": no effect, it'll stay on whichever network mode it was set to before. This is good since it means the SIM card is reacting and working correctly and overrides or ignores the wrong configuration
Redmi Note 4x @ xiaomi.eu weekly 9.1.3 set to "td-scdma only": no effect, stays on same mode as before. same behaviour as stable 9.5.2.0

This also means that 2G fallback just doesn't work for me because there's no LTE/WCMDA/GSM setting available. That stuff is kinda hard to troubleshoot but I went to a spot that has very bad 4G reception, no 3G at all, but acceptable 2G.
Went through almost all network modes and the only instances where it'd succesfully fall back to GSM/Edge was when set to GSM only, TD-SCDMA/GSM (useless) or LTE/TD-SCDMA/GSM (also useless because then you get no 3G)
Interestingly, I have analysed the wakelocks by night, and even if they don't add much to battery, some of them seem to be Xiaomi's metric apps that 'report to base' every 2-3 hours and wake-up the phone 133 times more than Whatsapp, Messenger and GooglePlay.....
Oh yeah uninstalling those metrics apps surely helps with standby drain.
Someone posted the short guide a couple weeks ago....had forgot about that:

That certainly helped lowering "Android System" drain. They'll stay uninstalled after updates and will only reappear after a factory reset.

High standby battery drain on 4G network

Hi
From the first day of owning my Le Pro3 Elite I am facing severe battery drain when network type is set to anything else than "Only GSM". On 2G standby drain never exceeds 0.4%, when set to "Global" or "LTE/WVDMA/GSM" it is about 2% per hour, which is ridiculously high.
The drain is the same under 20S baseband, flashing the 26S genesys to update baseband made no effect. Complete system reinstall, including baseband did not solve the issue. I am running the latest AICP 13.1.
Is anybody having the same problems?
I have the le pro 3 x727 n i had the same problem what i did was use suspend actions in the aicp settings what it did was turned the data to 2g when the screen was off and it fixed my problem

You should also use programs such as Doze modules in Magisk, Programs that you can download on Playstore such as Servicely and Naptime, which controls unused processes from running in the background. If you are using Pie. You can go into every app and control what runs i the background and what doesn't. You can further control what processes allowed allowed to ru while connecting to WIFI versus Data.
I think none of Magisk modules can help to make 4g standby drain less. For my X722 Im used that standby drain is about 2-2.5 % per hour. I have tried like 10 different roms and it stays the same, including the stock rom. I didnt have such a big drain with Le Max 2 so it's weird. Also I have heard other X722 owners had much less drain (some people even claim that drain is 2-3 % per night on 4g but I dont want to believe it). Maybe that has something to do with specific radio receiver or something which maybe can be different types even on the same phone models. If I want my phone to drain 1-3 % per night, I have to switch to 3g/gsm mode.
I've been using for 1 year Intelli3G module for xposed on my x720 .
You can set these combination : https://lh3.ggpht.com/xSrBFjXUhZ75h7MB5h8ZN3Xq6D1Uc3sutciiBNkU04rPG_BWfnKnZin9YtNYK3Q6wact=w720-h310
phone switches automatically to GSM mode with screen OFF
and to LTE, GSM/WDCMA mode with screen ON.
so you can limit the drain of battery at least a little bit :cyclops:
