Hi, i think my cell have a battery drain. I running RR rom 5.8.3. Redmi note 4x. Very high battery usage in the system. Should I change kernel? What is the best? Tks
help?
did you clean flashed rom? try wiping and flashing rom again
If you wanna try a kernel, velvet kernel is battery friendly, if you tweak the governor properly

23% doesn't seem "very high" to me. Why are you worried?

Unless my understanding of Portuguese is wrong, you seem to have 66% left, after 4 hours of use. That is 8.5% per hour. If you were using your phone actively during those 4 hours, it seems that you will get about 11 hours SOT, which sounds pretty good to me. If your phone was not being used at all during these 4 hours, then that would be pretty bad.

hi, i think isnt a good battery life. i tested and i have around 4/4,5 hours of screen time on, with 100% to 1% battery. the system is using too much resources, what im doing wrong??

You should get more than 4 hours SOT - and the screenshot that you gave in the OP shows that you would get at least double that. I am not sure how your battery can go from 66% (as show in the OP) to 1% in less than an hour. Right now, you leave us guessing about too many things. It is not clear how exactly you are using your phone, how many apps you have installed, what are they, what exactly are they doing, how you have tested your battery to determine your SOT, etc.
To find out what is the problem, think you first have to start with a clean ROM. As someone has said, do a clean flash first (wipe data, dalvik/ART, and cache, and flash the ROM). You should first backup your apps before doing that. Install "PCMark" from the play store, and run the PCMark battery test with the clean ROM. Then restore your apps. Then run the PCMark battery test again. Then we can see whether there is a problem.
By the way, here is a good way to test your battery drain.

I think 4hrs was not SOT and not the heavy usage either, because it shows top battery drainer was the system itself. I think solution to his problem is to try another kernel OR fresh clean install of ROM. If you do not want to handle apps and backup then may be just try kernel. I faced the same issue on RR because i did dirty flash (wipe: cache, dalvik, system only). I am using below mentioned kernel and it solved my problem. Plus i use kernel adiutor app to change cpu usage, but i have found that it has troubles sometimes. (i can't change values of max/min cpu speed & Governor settings, "sometimes")
kernel: faust v2.zip
app: kernel adiutor
rom: dirty flashed RR 5.8.3 (18/06) for mido

I currently have super clean 2.9.1 + voodoo kernel with JAMT minimalist theme, but I feel like I'm losing more battery than usual.
I had 2 full days of moderate usage right out of the box (wifi always on and screen half the brightness), but now it drops down to 20~30% for about 7 hours of moderate usage with 0 brightness. Also I'm getting random shut-downs at least once a day.
I've now calibrated my battery (at least I think so...don't know for sure), but the battery life stayed the same as before; short.
I'm impressed that I get 1500~1700 on Quadrant, but I don't know if that performance is ever needed for my usage...
I suspect that everyone gets different results with all the roms, but anyway which rom is the most stable with excellent battery life, and with no crash in general?

Random shut-down is probably caused by not flashin ROM properly.

No clashing just means that if you did install ROM properly or not most of the time.

I've already gone back to stock to 2.9.1 about 7 times, and yes I flashed Bstats.zip since the "wipe battery stat" option did not work.
Perhaps repetitive rom installation causes the crash? I don't know for sure...
It shouldn't crash even after times of flashin.
I've flashed my phone like 15 times now but works just fine.
Just go to CWM mode and Wipe Cache/Dalvik/Data and reinstall the ROM.

is it okay to restore my settings with red recovery (nandroid is it?), after reinstallation? or would that restore the crash problems too? I really don't want to set up settings/widgets/apps etc all over again...
and thanks for helping out again!
Nandroid Backup Backups to EXACT state u have backed it up. So, it would cause crashing again. I recommend you to backup data using TiBu(Titanium Backup). Then install ROM. I know it sucks to back up apps again, but better than your phone keep crashin, right?

I'm losing a lot of battery in standby mode. However, of I turn mobile data off, I lose about 1% every 5 hours which should be the case. Are you experiencing the same issue?
Mobile data is still not working on cm13 at all without toggling airplane mode. It needs more work. SHM has it working on Candy 6. I cherry picked that commit to make it work and made this ROM. Battery life is the same on this ROM as Candy. When more work is done on data I will merge it here as well. Note I got 18 hours screen on time on this ROM as well as Candy. I will look into cell data more and see what I can find. I still have governors to ads to this ROM. I can add the ability to not enable mobile data when WiFi is on.

Man, I'm not even getting 8 hours of screen time. I'm using the Candy ROM. Have you checked out the screenshots I PMed you ?
If that's the car it could be an app installed causing it. Or even a bad cell signal. If you are in an area with low or no signal it will cause the radio to constantly be trying to get a better signal. Tower hop. Hard to say. 8 hours is horrible.

Have you replaced your battery ? What is your standby battery drainage rate ? Man, something has to be wrong with my phone. How can we investigate ?
Maybe wipe and start fresh. Don't restore apps using twrp or titanium. Let android do it after install. Wipe cache and dalvik cache.

I always wipe cache and dalvik before installing new ROMs. I only use a couple of apps, so I don't want to really believe that the problem might be there.

Man, I'm going back to stock JB ROM. If you haven't noticed until now, I'm obsessed with battery life and getting less than 8 hours of screen time is killing me. All these new ROMs seem unfriendly to battery.
Here're screenshots of my battery consumption. I didn't even get 8 hours of on screen time. If the battery stats are to be believed, I've lost 3382mah and I'm down to 5% of battery. This means a full charge corresponds to 3560mah. If the battery capacity is 3900mah, then 340mah is unaccounted for. But 3600mah is still a lot of battery. Can someone check his battery stats so that I can compare it with mine and know what's wrong. I'm using Candy ROM.
@Moody66, I'm going to put your suggestion to test. I'm going to do a clean install of the ROM in this thread. After that, I won't install any app and then I'll let it sleep for 7 hours while mobile data is on.
Hello everybody,
about two months ago, I had an issue with my installed ROM on my Redmi Note 2 Prime (I think it was this one: http://forum.xda-developers.com/redmi-note-2/orig-development/rom-cyanogenmod-12-1-t3288916 ). I decided to try out another ROM so I installled Bule's Mokee ROM ( http://forum.xda-developers.com/red...nt/rom-cm-12-1-mokee-bule-mokee-blue-t3328382 ). After a few days with this ROM I recognized a big battery drain while screen off so I installed BetterBatteryStats to get some more informations. It told me that about 50-75% of the time my CPU was running at 800mhz instead of deepsleep (at a normal day with about 1-2h of Screen-On-Time). It didn't look to me like something is creating a wakelock though (but maybe I am just unable to see this). I tried the next ROM: Daniel Pinto's CM12.1 (http://forum.xda-developers.com/redmi-note-2/development/rom-unofficial-t3310551) and again the same issue! I tried a full wipe of my internal storage, did not install xposed and did not install any titanium backup. The battery drain didn't go away. So i flashed another ROM: SlimMIUI V7.1.3.0 ( http://forum.xda-developers.com/redmi-note-2/development/rom-slimmiui-dev-stable-t3296594 ) and suddenly there was no more screen off battery drain! This went well for about three weeks and now I am facing the old problem again! Please tell me what I am doing wrong since I don't believe it's a ROM-related issue.
I installed these apps (according to MIUI):
9gag
AdAway
Android System WebView
Antutu 3DBench
Antutu Benchmark
AquaMail
BetterBatteryStats
BikeComputer
Burning Series
Chrome
DB Navigator
Dropbox
ES Datei Explorer
Google Play Store
Google Play-Dienste
Google-Tastatur
Greenify (wasn't installed before SlimMIUI)
GuitarTuna
Hacker's Keyboard
Hearthstone
irplus
Maps
Messenger
MX Player
mydealz
No-Frills CPU Control
Nova Launcher
Open Camera
PaderSprinter
QuickPic
scondoo
SleepTimer
Spotify
SuperSU
Telegram
TeslaUnread
Titanium Backup
Twitch
Unified Remote Control
Wakelock Detector Free
WhatsApp
Youtube
What I have tried so far:
- changing ROM (clean flash)
- not installing xposed
- not using old backups
- changing the battery
- using airplane mode
Also, I wonder why there are these gaps in the battery history since I didn't reboot yesterday...but these gaps don't appear every day.
Please help me to fix this really annoying problem and make my RN2 great again!
Thanks,
Kooneybert
The biggest drain comes from all the Xiaomi bloat. Read this thread for details on how to reduce the bloat. In my experience, the second main culprit is WhatsApp. I've had to stop it from giving sound notifications (or even vibrating) when messages come in. Now, I have between 90%-95% deep sleep on idle. Basically, anything that turns on audio could be a problem, because sometimes audio doesn't go off afterwards.
You might want to try GSAM Battery Monitor for more information about what is eating up your battery.

Thx for your reply! The problem is not MIUI-exclusive. CM 12.1 from Daniel Pinto is pretty slim but gave the same result (from the first day on).
Whatsapp can't be the only problem since all my friends use it and nobody have this problem (some of them also even have a RN2). Also, my phone is in silent mode almost all the time so no app is allowed to make noise or vibrate.
I just installed GSAM Battery Monitor but I don't know how to use the app/read the provided data. I could use some help there, too.

You can only be sure if you have a really skinny ROM whereby all the unnecessary Xiaomi stuff has been removed. There are all sorts of things going on in the background - including things embedded in the boot image.
There are also possibly optimisation issues with the kernel. All the ROMs seem to depend on the same binary kernels, since there is no GPL release of the kernel source code. You might want to try one of the skinny boot images by @jajk
As for GSAM, the best to learn is by trial and error (tip: tap on everything visible to see where it leads to, and what information it gives you).

...on all three ROMs? Only for me? With this effect? On some days, it reduces my battery by 50-80%! Hard to believe it is not a bug. Also, SlimMIUI has reduced Xiaomi-Stuff, Daniel Pinto's CM 12.1 looked even more clean to me.

Aren't there different kernels out there for the RN2? Bule's Mokee-ROM uses a modified kernel e.g. Does every ROM come with a certain kernel or may it be applied from the ROM before? So maybe I am still using the kernel from Bule's Rom with my MIUI?

This will help me to read the information but it won't help to understand them, too. What do you think about this:
Kernels: You can't compile a custom kernel without the Xiaomi kernel source code. All you are left with is tinkering with ramdisk in the boot image

...is this normal? The Kernel is the biggest battery sucker on my tablet aswell (which still has great battery). What do you think about the 8,5h of wakelock time produced by the kernel? If this is the problem, what can I do to solve it?

A "screen awake" of approximately 50% seems to me to be highly excessive (at least, if the phone was mostly idle). In nearly 12 hours, I have a screen awake of 55 minutes - so 8 hours in 15 hours seems strange. How exactly were you using your phone during this 15 hour period?
Perhaps the custom boot images by @jajk might help (see the first link in http://forum.xda-developers.com/redmi-note-2/general/roll-skinny-miui-t3309873). I am currently on v714-15 of the custom boot image.
Sounds like you may be having issues similar to what I was dealing with not too long ago, but my 'solution' was to install Bule's Mokee (still don't know why this ROM worked where so many others failed). Daniel's CM 12.1 and Xiaomi.eu were both giving me significant drain with and without the screen on to the point where I was sometimes finishing the day with an hour and a half of screen on time and ~20% battery. Now I'm getting up to double that.
One thing I can recommend is using MiFlash/Fastboot to do a total reset from scratch. Didn't really work for me, but you may be different.
Other than that, although it's tedious, you may have to install 1-3 apps per day after a fresh install to see if your battery holds at first and then dies sometime after installing certain culprits. It takes forever, but at least this helped me when I moved to Mokee to make sure that it wasn't any of my 'vital' apps that were causing me issues.
Best of luck!
Funny thing that the Mokee-Rom did SOLVE your problem. In my eyes this Rom was the beginning of my problems.

What is the difference to using TWRP?
I will try the Mokee-Rom tomorrow. Since I never used MiFlash/Fastboot before I won't use it until you tell me that there is a difference compared to doing a full wipe with TWRP.
I tried flashing the Mokee-Rom again but the problems go on. I installed very few apps and the battery is still very bad. Today I had 18 minutes of SOT and though I lost 14% in a few hours. This time it was caused by Whatsapp:
It always seems that some apps just don't like to stop doing something but it's random which app is the problem.
I am totally running out of ideas so please help me guys!
I'm on Mokee and satisfied with battery, this rom have less problems than other (for me). First of all i have installed MobileRadioActiveFix with xposed, then SmartNetwork to turn off wifi while my screen is off. I've got few other things but right now i've got over 4h SOT so it is not bad score.
i have the same problem! it happens with flashing severals ROMs (mokee by bule?) and starts battery drain with all ROM, it never goes... is not the battery, the cable or the rom..... i dont know im disperate... the sot changed from 4-4.5 h to 2-2.5 h... with all ROM, please help us and sorry for my bad english
Well i had situation that my SOT suddenly got down but i was still on march rom. After update to latest version without wipe it is ok right now.
Have you tried with wiping all with internal memory? Maybe something is there still and that is making a problem.
Another thing that came to my mind: have you changed build.prop and have copy of it? If so, delete it. I had some problems becuase of that.

every rom i have flashed was a clean install (full wipe of internal) after latest miui update, when the phone shut down at 0%, i put off the battery for 10 min, after i put back and the phone was at 19%!! now is on charge... maybe the problem is solved.. i will post if it is solved (sorry for my bad english)
I had that problem with earlier phone and it drived me crazy. I was not able to find what was the cause unfortunatelly. Phone was given to service point to install branded rom (it was not available for public). Right now i do not have problems like that, if i have some i'm able to find solution somehow. Although what i wrote helped me when i saw SOT problem.

Not that I know of. I`m facing the same issues like you here.
You can try:
-discharging until the phone shuts off
-charge it in OFF mode until its full
-disconnect charger, put battery out and in again
-connect charger, charge it to 100% again...
repeat until it shows 100% when connecting the charger.
For some ppl this seems to work.
Please let me know if you find out something!
There are lots of ppl out there with exact the same issue!

EDIT: Installed PSYROM V3 for testing purpose right now. Lets see how it does with skynet and a freshly calibrated Battery with the internal calibration tool of the rom. I`ll give feedback on monday.
Update to my issue:
-I did a full wipe (including internal memory)
-Installed PSY ROM V3.0 and Skynet
-Wiped cache/dalvic
-Startet the phone, installed my apps etc
-Charged it to 100%, waited 20 more minutes
-Did the Battery calibration with the internal calibration tool (everything is described in psy mans thread)
-Did a reboot
So far there is no Battery Drain, after the (long) reboot, wich took around 5-10min because miui is optimizing apps etc the phone came up with 97% and stayed there for almost an hour now.
I´ll give you guys feedback next week. Hopefully we get this sorted out.
You can try Angels & demons ROM v8.0 it is providing me with great battery life, so much better than stock or stable version of MIUI. I use Gsam battery monitor, and I have not faced that issue so far.
I have tried pretty much all AOSP ROMs and I am finding that all of them have huge number of wakelocks. At night my phone is awake for about 1.5 to 2 hours out of 7-8 hours and drains 7-10% battery over this time. Even with clean install and only minimum apps installed.
In battery useage apps they show up as Kernel (Android OS) and Linage OS System in battery usage apps. Any idea how to find and resolve this?
same for me!
This only happens on AOSP roms? Not on Lineage OS?

I included Lineage OS and everything else in AOSP - non MIUI ROMs.

So this doesn't happen in stock rom? I'm getting my Redmi 5 Plus today and i plan to flash a custom rom because i don't like bloatware and gapps, but if this is a big issue i don't know if i should for now.

I don't think so. Stand by on Stock ROM was much better for me. Lost 0% overnight.
same happens to me.
Same for me.
same here. 1% lost every hour overnight, just mobile signal, no wifi, no bluetooth no gps
Try using AppOps to deny the following permissions for the apps you have installed - keep awake, auto start, run in background. Exclude messaging, clock and dialer apps from this procedure.

These guides can help, but are most likely not longer necessary past Android 7.
I am doing a test by clean flashing, not installing any apps and not even installing Gapps to see if the same drain happens. Will report back.
Cleaned flashed, NO GAPPS, NO other apps, left phone for 8 hours, lost 8%. "Significant motion detector" was awake for 2.5 hours. Same wakelock on all ROMs, seems like an issue with this phone. I don't know if it happens on MIUI but I guess no?
It might be because all the ROMs are based on the initial work of mdeejay and tingyichen, as I understand it. All the AOSP ROMs are basically the same, only varying in tiny amounts of superficial stuff that is added to them.
Did you try the unofficial OmniROM build? It's the only non-Lineage ROM that's developed from scratch (by ex-CM devs), and to me it does feel different than all the rest, in a positive way.
use better battery stats for understanding the culprit. i am on 8.1 AEX and overnight drain is 0.5%. 0n miui it was 1%.
Sent from my vince using XDA Labs
What phone do you have ? 3/32 or 4/64? And what baseband firmware? I ask because I had same 1% per hour drain on aex too. I wonder if having encryption on makes a difference?
I am tired of trying new roms and kernels but all behave the ssme. 35% time awake
Can you try to post a Better Battery Stats log? Is your WiFi turned on during idle?

No, everything turned off, only mobile signal. Also tried in airplane mode.

Please post a Log from Better Battery Stats. The only thing I can think of is that weak signal is draining your device's battery.

Not possible if its happening even in Airplane mode.
Hi i was first using PE then switched back to miui via fast boot rom then after a few days i noticed a sudden fast battery draining, tho it charges faster but it also drains at a high rate. Now i switched to eu rom hoping for an improvement but nothing has changed. What would you guys suggest?

Hi!!! It doesn't seem to work. I already changed rom and kernel (arter) but this doesnt seem to be the solution. I think replacing the battery will be the only way left

I think you should revet back to miui stock non root and make factory reset and test your battery again

Also, try to make complete charge cycle (Drain it to 0% and charge it to 100% when your phone is shutdown) and test your battery drain again
try this kernel
LawRun-Kernel™

Switch to MIUI EU 11.0.5 ROM
Flash Magisk
Flash Twisted Kernel
Install Spectrum App from Playstore
Select Battery Profile
Enjoy 8-10 hrs SOT !!!
before you could take bold decision to change the Battery!
flash 9.6.x vendor / firmware
I have always found Higher batter drains on vendor+firm higher than 9.6.27-9.0 !
also would recomend to do CLEAN FLASHING (if formating data is possible for you ) then do it (take all backup)
more over if you using application which is depending on Screen like (gravity screen) or ambiant display for screen to wakeup randomly whenever music track change or whenever you recieve any notification, PLEASE disable them! , third party apps sometimes abuse sensors and affect performance!
for kernels, I myself found difference between battery performance in various
I use Twisted kernel (pie) (since i am on pie) but you can try Opitimus drunk, its also amazing kernel!
if in custom rom you are laydown apps via rooted method such as
1. MIGRATE or
2. TITANIUM backup
then all the bitter settings from any malicious battery draining third party app is also reinstated! hence keep close eye which apps actually to restore with DATA!
