So, like you maybe seen, I also used BM46 Redmi Note 3 battery in my RN2. Now I have some problems, maybe someone can help me with it. To see, how I transformed the RN3 battery for my RN2, look in "Best SOT so far (Screenshot)" thread in this forum. So all is working fine, only my phone is shutting down at 20% (like when someone removed the battery). After that you cannot boot it up annymore, because when the booting is done the phone shut down again. I pluged it in only for the boot process and after it, I can remove it again and can use it, until it reaches the 0%. Maybe someone know how to fix it.
Marry Christmas and a Happy new year ^^

here the thread where is shown, how I transformed it
It may be caused by the rom you are using, I experience the same thing when I'm on 7.1.1 and 7.1.3 modded roms. When restore back to the original Miui 8, the problem solved.

I am running Android 6.0 Marshmallow on my Nexus 9 build number MRA58N. Device is not rooted but the bootloader has been unlocked and I am running everything on stock. Clean fresh install about 5 days ago. I did face some trouble trying to root my tablet at first (boot loop) but instead I formatted and just reflashed the firmware clean using (flash-all).
First few days, performance was below average, lag here and there but it was acceptable and it did go away after a day or so. Could be the tablet adjusting and syncing with the recently installed apps.
What I did find unusual though was the battery stats. It showed numbers (99013, 99023, 99033) processes which I am unfamiliar of. I tried googling it and searching on the xda forums about this but have not found any post on this. Is anyone else experiencing this? Is something wrong with my device? It could be the culprit to the overheating and battery drain.
(still trying to find out how to upload the screenshot, if anyone could help out with this, it would be much appreciated. PS: xda says that I have to make at least 10 posts before I can share external links, so I don't know how to make imageshack work here. Or I'll just make the 10 posts somehow.)

I've seen those numbers before, however not sure what they are either.
What type of battery are you seeing.
When I was on stock mra58n I was seeing around 4-5 hours screen on time and about 4-5 days overall time on. I thought that was pretty good. I only lose about 1-3% overnight so I could let it sit for quite awhile untouched and still have a charge.
I am now on PureNexus Android 6.0 ROM and seeing about the same but slightly better battery. I'm seeing 5.5-6 hours screen on time and 6-7 days overall time on.
This is with ElementalX kernel which I highly suggest.
How long have you had the tablet? I just got it on the HTC 40% of sale.
I recently have been having the same problem, as seen here: imgur DOTCOM /a/IMqFW, you can see the "99006" active, right now another has appeared with "99040". I saw these number a week or two ago. I've had my tablet since may or so. I posted on the reddit r/Nexus9 for help, someone suggested that it might be some sort of old application which left a few things behind when it was removed from the device. I don't really know what to think of this.
Hi,
I also observed a drastic battery drain and going to the "battery" section in settings, i found a weird "99040" thing with a black android robot icon, draining 16% of my battery.
I don't know how to remove this and I suspect this is malware or something related.
Does anyone know how I can remove that sh**** ???
Best regards.
Hi! I've been reading this forum on and off for few years, but never actually posted. Hope someone here can help me sort out my issue, thanks in advance!
Basically, I've flashed a cm13 via custom recovery on my second phone - Xiaomi Mi4, and I'm having all sorts of issues with it. I bought the phone in China, and for a while
used the stock MIUI interface, but I hated all the bloated apps and weird pop-up advertising, so decided to flash. it was the first time i've attempted it, so it took some
time to figure it out
My two main issues with cm13:
1. It crashes and restarts two/three times daily for me. I mean, I've cleared cache, I basically have no apps on the phone (apart from few messaging apps and facebook).
Is it just because it's an early cm13 build, or it's a nature of custom roms? I'm wondering if switching to a snapshot cm12 build would be better? I don't really care for
android 6 features on this phone that much, I just want a stable experience.
2. The charging became uber slow, painfully so. On MIUI it'd charge to 100% in about 3 hours or so. On cm13 it takes 3-4 hours to get to 30-40%! Never seen anything like
this. Also, if the battery depletes to 0%, the phone wouldn't turn on, even plugged in for charging. It'd turn on after an hour or two into the charging process. Seems weird,
as every other android phone I've owned previously would turn on even with 0% battery if I'm plugged in.
Anyone else experience any of the listed issues? Is it just an early build, or I've done something wrong in the flashing process? I really just want a stable simple os, no advanced
features or whatever, just need it to work
Thanks!

Thanks for reply! Would you mind telling me which gaps you've used for your build? I remember I had some sort of an issue with few gaps
I tried, I think only the smallest package worked for me. Maybe that's the issue and something in the gaps i've installed freezing/rebooting my os?
Thanks
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.
problem persists... is there a method/app to calibrate battery that works?

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!
BR
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 greet you all in the name of peace my fellow comrades.
4 days ago i joined you in the xiaomi smartphone race by buying xiaomi redmi note 3 pro. Everything was fine and nice till I found out the very first day that my phone suffers from huge battery drain overnight. I did my research about this matter already but was unable to find any clear and soul-soothing answer unfortunately, so I'd like to ask you if you could help me by sharing your experience and opinions with me.
I'm not going to pretend I'm not a hardcore noob in miui as it is my first xiaomi phone and generally flashing/rooting too since the last time i was flashing anything was like 4 years ago on my galaxy s1 i9000
So to make this post as short as possible:
I'm on stock OS - exactly as it came from the store - android v.: 5.1.1 LMY47V , security patch level 1.8.2016, miui v.:MIUI Global 8.0 | Stable 8.0.2.0(LHOMIDG) , CPU: hexa-core max 1,8GHz , no mi account yet, no unlocked bootloader, no root.
observation:
I downloaded cpu spy from google store. thanks to this app i came to know:
1- the phone never goes to deep sleep but stays on 691MHz or higher all the time.
2- after turning it off and on again, it can enter deep sleep for several hours. then I browse a little on wifi, check gmail and so on or whatever.. after some time, the phone usually doesn't get to deep sleep anymore.
- in battery use, android system and android are shown as the two major culprits (high percentage). When i click on the "android" process, high "keep awake" time is only present here. not in "android system"
cause?
D) Google Services? http://en.miui.com/thread-356299-5-1.html according to another guy, "they are working on a fix" -?
E) fingerprint wakelock? http://forum.xda-developers.com/redmi-note-3/development/kernel-t3414884 fix by flashing older modem - doesn't seem like my problem,. but what do i know right?
F) something else?
fix?
A) should i try to upgrade to 8.0.6.0.LHOMIDG | stable ? not sure, because miui forums are filled by users complaining about bad battery drain in this version.
B) Do i need to unlock it and get another ROM to solve this problem? According to this guy, changing ROM didn't help him https://www.reddit.com/r/Xiaomi/comments/5af17d/battery_drain_on_xrn3_pro/ i try to avoid flashing as long as possible
C) is there even a fix?
I already went through this guide, but it didn't solve the problem http://en.miui.com/thread-339815-1-1.html
I bought a new phone and expected it to be working right out of the box, instead I've been just googling and googling for the past 4 days to no avail. I'm really confused and desperate in this matter and don't think I'd be able to continue looking and find a fix to this problem just by myself.
What should i do? I have time till next week's Wednesday to return it back to the store for full refund... or should I return it right away without any hesitation?
Thank you in advance for your reaction.
I've had this phone for some months now, and with normal daily usage and a custom rom, I can make it 4-5 days with 1 charge which is nearly impossible with MIUI ROMs; from personal experience at least. If you do not want to upgrade/change your rom, I would suggest you unlock your bootloader and root your phone. After that you could try installing "Greenify" from Play Store which really helps hibernate apps. I've been using it for over a year and it makes my battery life last at least 2-3 days more with normal everyday use. If that doesn't help either, you could try installing a custom rom which generally is "lighter" compared to MIUI roms. Hope I helped, good luck.

MIUI doesn't need Greenify because it kills apps automatically by default. I use it on all my devices except my RN3P.
My suggestion would be to go into the permission manager first and disable everything but the non-essential functions. Next go to background permissions in Additional Settings and do the same. It took me a few weeks to get things working properly and now I average about 6-7 hours of sot.
I still have some apps that keep occasionally have long keep awakes but force stopping them brings them back to normal. For example a 30 minute keep awake from bbm will show as only 5% on the stats but will account for a full 10% per hour on it's own. I've now removed it from the whitelist and allowed miui to control it. Hope this helps.
Hey, I have a redmi note 4 snapdragon version and I have flashed aosp extended rom and franco kernel in it, but I am getting a very poor battery life, hardly 1 hour screen on time and the phone shuts off by the time battery gets to 30 to 20%. My phone is rooted too and i am not using any kind of battery saver app.

The problem started probably when i rooted my phone on stock rom(miui 10), the very next day i cleaned every thing (including my firmware accidentally) to flash custom rom, then after flashing i found out that none of the hardware components are working and i posted a thread about it and as per the answers i flashed a latest chinese firmware for redmi note 4.And it worked except i started noticing an awfully bad battery backup(hadn't noticed before as all this happened in just 2 days. (as a matter of fact the battery went down 5% as i wrote this, oh 6 now!)

I have the same problem, the battery die after 1h screen, when the battery Is on 20% the device shutdown,help me pls, i have rr with franco kernel.
hi OP. base on what you are describing, it looks like your battery is dying... nothing to do with the OS. be careful 'cause chinese batterys (like 70%) turn out to be real sh*t (on my own experiance). consider to replace battery from a confiable retailer or change device.
