brutal battery drain - Xiaomi Mi 9 Questions & Answers

Hi, when I'm at work, it happens that the mid 9 becomes hot and the battery runs out quickly. Then without doing anything it comes back to normal. Have you ever had this problem?
Many thx.

The same thing(...

hi all, i tried to figure out this problem.
I notice first that the problem doesn't occured at home where i have great battery life. I decide to install BBS and see what happened.
i discovered that at work, when phone become hot and have battery drain fast, in BBS, i have a kernel wakelock named 1-0028 that keep phone awake.
with all my search , it seems that the wifi at my work is the cause. try to stay on LTE and have no battery drain at all.
Don't know why but if you have that problem, don't use wifi if possible and stay on mobile data.
If anybody know if there is setting on mobile or on wifi , share it

Maybe its the wifi trying yo look to networks to connect to, have u hot it on

[Q] Help!!! Battery drain ultra fast after upgrade to ICS stock rom

My battery drain very fast after upgrade to ics stock rom.
Got any way to solve it, like settings, etc?
you could use the built in power saver mode.
But we need to find the culprit, Install a monitoring app and /or check the battery stats regularly to see whats causing it.
How did you update to ICS ? Did you do a full wipe before hand ?
direct upgrade thru kies without wipe data
ok, well do not wipe data until you flash a safe kernel.
monitor your battery over the next few days with a monitoring app like watchdog or similar
if it doesnt improve, we will look at doing a wipe and starting from fresh
well....got the same prob....am on rocket rom v7...
the issue is that the battery drains really fast when m connected to h+ network!!
i even put the fone on flight mode and kept it like tat whole night and in the morning cpu spy showd that the fone was on sleep for awmst 7 hours, and the battery drain was just 3 percent!!so tat seems awrt!!
i jus dunno why the battery drains so fast when m connected to the network!!
plzzz a soln will be appreciated!!
Thanxx!!
Maybe you could try a different radio ??
If your current radio isnt finding a strong signal, your phone will be constantly searching for something better, Thus resulting in a lot of drain

It is probably just L2_hsic bug.
Just reboot the phone and search the forums for ways to prevent causing the bug.

I test one method, 3 day, seem like work to reduce battery drain issue.
1. turn off phone
2. remove battery for 2 min
3. plug in battery
4. start phone

Galaxy note over heating (System UI hogging CPU)

Hi,
I've a G-Note running ICS-4.0.3 , i recently noticed my phone is getting really hot and resetting automatically at times, on closer investigation i see 'CPU spy' data showing my phone running constantly at 1400Mhz mode!!! wanting to find which process is doing this, i downloaded watchdog lite and noticed that 'System UI' process is running at 49% approx CONSTANTLY, killing it re-spwans the process!! any idea whats causing this?? Please Help!!
Not rooted, never flashed, on original upgrade, have nova launcher, use it rarely. no other launchers installed.
Restart fixes this sometimes, sometimes not.
Thanks in advance,
Ramgo.

Not that i can think of as a problem, been happening for a while now, could be any of the app! i have like 200 installed!!
Now its not system UI, its android syste, badass battery monitor shows kenel to have taken most of the battery (which seems mostly loop task, is this bad) and then android core process.

well try to remember from which app on this issue showed up.I had battery drain problem turned out it was because of an app that I had installed.So I unistalled it and my problem went away.Yours should be easy to spot try unistalling the recent apps or the ones you're suspicious of and see when you get deepsleep.
Check your battery status and see for the battery eater apps

I infact got deep sleep the whole day, 15 hrs just 10 percent drained! this problem has been occuring intermittently, deep sleep is still happenning, but when the phone is screen ON, its in the highest mode.
Hmm things got complicated.Like I said if everything used to be normal then all of a sudden this problem began then it should be an app I suppose?!Just like my case.
Install OS Monitor and see what's hogging your cpu maybe you can pinpoint the application if that's the case.
did anybody have a problem with Gsam battery monitor after it was upgraded from Badass battery monitor??? i was looking at it and was showing 100% battery drain due to application ( 0% for screen and phone radio)!! i have uninstalled it and seems fine i guess! atleast for now! charging now and its in the expected 200Mhz state.

Yes will do that!! Thanks! read my comment below, i think GSam Battery monitor submits some task or makes some query to the kernel which makes it to go in a loop, hence the android system seems to be using more CPU and not battery monitor itself
The problem is back!! HELP!!
I checked OS monitor, nothing seem to be hogging, occasionally android system, overhearting near the camera and resetting automatically, please HELP!!!

Hello,
I'm having a similar problem. When my Note is in standby sometimes it overheats without any apparent reason and battery drains very fast.
I haven't been able to trace the origin of this problem. I'm running on ICS 4.0.3 stock and no ROOT.

Have you installed any kind of launcher on your phone? If you have, do try to uninstall it for now. Install BetterBatteryStats, turn off any data connection.. 3G, Wifi, Bluetooth.. Remove any Live wallpapers(just use a static one), Uninstall any apps that connect or syncs online.
The last thing I could advice you is turn off Airplane Mode (at night), charge up your phone to 100% and just leave it for a day. Check back on BetterBatteryStats after on what apps/wakelocks is triggering the overheating.

Lot's of work... I'll have to find some time to try all of that.
Thanks.
Early last week my Note started to reboot whitout any apparent reason. It happened 2 to 3 times a day. Specially in the morning when battery was still above 60%.
The overheating also happened from time to time but not everyday.
Saturday I figured I had to do something extreme to end this.
First I downgraded to a pre-rooted GB rom. Afterwards wiped the GB rom. Then upgraded to stock ICS. Everything worked out fine and was very easy to perform, thanks to all the guides available on XDA.
Last of all I rooted the ICS.
Until now the Note hasn't overheated or rebooted again.
I really thought it would be harder to do all this. But now I think it would take me about 20 min to do all these procedures.
Thanks to all the people that posted the guides on XDA.

I'll take that as a joke.
Three days in and still no unwanted reboots or overheating.
Gents if you have nothing constructive to provide in assisting the users with real help, please refrain from off topic mindless humor. Thank you.
A week after I've re-flashed ICS on my Note, the unwanted reboots have come back.
It must be some app I've installed again or maybe something much worse. I've read lots of threads and was wondering if a custom kernel and a different ROM might solve this problem.
One thing I've noted, the reboots never happen at night only during the day (mid-morning and mid-afternoon).
Any new ideas to help me find the source of this problem?
EDIT:
I'm running on LPY Kernel, so wipe is not an option...

Battery usage

Hi all,
First off, thanks in advance for any advice.
Second, if this wrong place or a better thread elsewhere, please let me know.
Now on to the question. My battery drain is quite significant.
Phone has been on for 11h 51min. Charge is down to 45%. Ok I can deal with that (still would prefer better) but my usage is what is baffling me.
It says the screen has used 47% of the battery usage. Screen ontime is 59mins.
Is everyone else seeing usage rates this high?
If it matters, mine is an Optus XXALI5 firmware.
Thanks again.
Pete.

Thanks winwiz.
I did read through that thread but did not think it was the same issue.
Just to confirm, fast dormancy is a screen issue and will minimise my screen battery usage.
Can I apply this fix without rooting phone? Want to keep it stock for a little while.
Sent from my GT-I9305 using xda premium
I think the phone has to be rooted.
Be careful though as I applied the fix as a test and my battery drain went down terribly. This is afaik becuase my network does support FD. Several users have commented in other threads that it is not Network dependant but from my tests it definately is.
Also I found that my phone became quite sluggish and do not remember doing anything else on it at the time. No big deal just re-flashed the rom and it back to normal.
Just sharing my experience and a word of caution.
EDIT: FD is not connected to the screen, it is a way the phone handles the radio in connection with the network by putting it in to a sleep state if there is no activity.

Fast Dormancy is definately Network dependant. So you really need to find out if your network supports it. Because if your network does its better to leave it on
get betterbatterystats and have a look at what's draining your battery. the screen will almost always have the highest usage percentage, it's a hungry beast.
i'm guessing your phone isn't going into deep sleep properly.
install betterbatterystats, charge the phone to 100%, use it normally, and then in betterbatterystats use the dump to file option and attach it here and i (or someone) can take a look at it.
my initial suggestion without seeing BBS would be to try disabling LTE - just use WCDMA only (or GSM only) and see if that helps. LTE is a real battery drainer.

[Q] battery drain - can't identifiy despite bbs

hey guys,
i have a problem with my i8190 since i've bought it... the os is draining battery and i'm loosing about 20% battery over night...
i've tried several things:
installed newer official versions from samsung
deactivated nearly every app
calibrated battery
tried benzrom
tried juicedefender
but still no success.
can you identify something in my bbs??
thx in advance
I have the same problem, i had a full charge at night, then i woke up and the phone had 50 % battery, GPS, Bluetooth, Wifi were off and it drained half my battery, also installed CPU spy, and i notice that my phone is not going into deepsleep, i only have 5 hours of deepsleep and dont know when that was, i have the latest firmware, anyone else having this issue?
It's normal for this phone. Put the phone in airplane mode at night helps me with battery drain, just 2% juice gone.

install adaway
should decrease the battery drain and free up some memory in the process
Well for mine it was an app called Jango, for some reason this app after quitting it wouldn't let the phone go to deep sleep, removed the app and now its going to deep sleep.
Use JuiceDefender or or try to change your brightness level.
Please reply to my better-battery-stats...
I has nothing todo with screen brightness
thanks for the tip with adaway... i'm already using it... but no success
@kicker63: this can't be, when i see people having the s3 mini with up to 4 days usage

Your battery might be defective i guess, if deep sleep is that long and you're losing battery, i guess u have to blame the battery
I don't believe people get upto 4 days usage, if they do they hardly use the phone. Most people on here say about 1 days usage is common. Screen brightness on full will drain your battery more quickly.

It's a long shot, but I also experienced a lot of problems using Viber.. JuiceDefender etc wouldn't solve it, betterbatterystats wouldn't detect it, ...
Just noticed after a while that my sudden battery drains were triggered as soon as I received a message on Viber.
I also heard about facebook apps draining the battery.
Maybe you should first try to reset it to factory settings before asking a new battery?
Good luck with your phone, I know it can be frustrating..

If you're rooted, use greenify to stop facebook from running in the background during sleep
resetting the phone wouldnt help since he is getting almost 99% deep sleep reported in BBS

[Q] Horrible battery on 4.3 sense roms?

Has anyone else had this problem? since upgrading to a 4.3 sense based rom (tried 3 different roms), my battery life has become horrible..i can barely get 2 hours of screen on time whereas i used to get 4+ on 4.2.2 roms.
i know alot of people have said that 4.3 improves battery, but it hasnt for me, its done the opposite.
also has anyone noticed strange heating up of the device? for example in asphalt 8 the device thats slightly hot and then cools down while playing. but in games like candy crush or zynga poker the device continuously gets hotter and hotter..
tips/fixes/stories anyone?
Mine has been really good. Like, 3-4 hours screen time good. When I'm on wifi (N only, G wifi drains a lot) my battery percent just flatlines on the graph until I pick up the phone again. Sounds like a rogue app since I don't have this issue. I run ARHD 20.1.

I'm running arhd 20.1 aswell. And I would LOVE to see that happen again, my battery drains around 10% overnight, and I'm a really late sleeper, so that means in 5 hours it's lost 10% on standby..and it's weird cause WiFi shuts off after about two hours,so I know that's not causing the problem.
App usage shows android system as the app using the most battery. When I check in the morning it shows android system and kernel to be the top two users.
Could it be a radio problem? I've seen a decrease in signal since ive upgraded to the 4A.17 radio from firmware 2.24.
I'm thinking about flashing the minsense Rom or even a ge rom and see if that helps the problem.
It doesn't seem to be a rogue app cause I actually have less apps then I did on 4.2.2, and none that are new..

I'm still running the current T-Mobile firmware, not 3.x. (I'm still S-ON with hboot 1.44) Thought that was worth noting.
Have you tried putting the phone on WCDMA/GSM auto instead? If your LTE signal is weak (or any kind of signal is weak in general) I see this phone's battery life usually take a nose dive. It has so far from my testing saved me a ton of battery to switch the phone manually into GSM only when I'm inside a building at work to get more bars, then switch back to LTE auto when I leave. Try leaving it on overnight on different radio settings, and with and without wifi. It could be a cell radio drain. And btw get GSAM battery monitor, the stock stats don't seem right to me. Android System being high in the HTC battery stats tells you nothing really from what I'm seeing so far.

the funny thing is i dont have data, since i get wifi wherever i am. i also think its a radio problem though, my gsm signal never seems to be full, and people constantly tell me on the phone that they cant hear me. so what im doing (right now) is flashing a ge rom, specifically sinless rom, then im going to flash the new ge radio, 4A.18, and see how that plays out, prolly going to flash a 4.3 kernel aswell so i can uc to 162mhz or whatever the value is.
i seriously believe its the radio+lack of kernel on 4.3 sense roms that are causing this problem for me. so once this is all done ill test it for the rest of the day and see how it goes. thanks so much for your help

If you don't use any apps, of course system uses the most.
You need to check for wakelocks. If you have unexpected battery drain, it's likely that the phone is not sleeping properly, i.e., being kept awake. Betterbatterystats, gsam, wakelock detector etc.
What was the change in signal attenuation, or are you just saying the the display bars are different?

i use apps, just nothing new compared to when i was on 4.2.2.
and no wakelocks according to gsam, i lost 20% overnight (7 hours)
i dont get what it is. i upgraded the radio to 4.19 now, but for the signal issues, it included lower bars, bad audio in calls, and random loss of wifi.
i removed basically every app, besides some essentials like facebook, whatsapp, and a few others.
i tried switching to an ge rom, but i just cant stay on it for too long, vanilla android is so plain compared to sense.
so the last thing i can think of, is a rom known for its battery life. not asking for a comparison, just your opinion in which rom gives the best battery on 4.3. any suggestions?

i removed basically every app, besides some essentials like facebook, whatsapp, and a few others.
i tried switching to an ge rom, but i just cant stay on it for too long, vanilla android is so plain compared to sense.
so the last thing i can think of, is a rom known for its battery life. not asking for a comparison, just your opinion in which rom gives the best battery on 4.3. any suggestions?

Charge your phone up all the way, put it in airplane mode, and unplug it for an hour then don't touch it. Then post your battery percentage. If it isn't still 100 or 99 then you have a more severe problem that actually relates to the battery itself.

good idea, testing it now, will report back in an hour.

been an hour and 5 minutes, still 100%.
so im guessing it has something to do with the radio?

Show us a graph of your signal strength from GSAM, and show us a screenshot with how many bars you have. At least you know now that the battery is definitely not shot. It is probably mobile data related...hmm did you ever try letting the phone sit with mobile data disabled as well? It should drain almost as minimally as airplane mode.

So wait, your signal is really good but your phone drains like crazy, and while you're on WiFi? Okay, what wifi router are you using and is it G or N and is it dual band?

its absurd i know..its already down to 93% with 9 minutes screen on..
and its a dual band router, im normally connected to the 2.4ghz band, and its with wireless ac, which the one supports. Which is weird cause i thought ac improved battery life..
edit: im an idiot, wireless ac only works on 5ghz bands, but that still doesnt explain the drain on wireless n..as my previous router was also wireless n

Have you tried 5 ghz N by forcing the router or your phone to operate only at N speed? I use a TP-Link dual band N router and I remember seeing s drain of about 4 percent overnight for 8 hours of full idle with full sync.
I have tried with both 2.4ghz n and 5.2ghz ac, same problem persists
Awake is 3x screen on, I don't think that's normal, somethings keeping the phone awake much longer

so ive done a bunch of other tests, and i can confirm its wifi thats causing this massive drain, not wakelocks, not roms, or anything else.
when the phone is left with wifi on, but not being connected to any network, battery drain is minimal overnight.
its the same on both 2.4ghz and 5ghz bands, so it this a router problem? if so, do you know any tips that could fix it?
Do you have "Best wifi performance" checked? That seems to eat battery.

i have no option for best wifi performance, just "wifi optimization". i found the problem, it has something to do with my new router and its bad compatibility with android devices. the phone seems to be awake 2x the screen on time and the main culprit is "wlan_rx_wake" wakelock
