Massive screen-off battery drain with all ROMs - Redmi Note 2 Q&A, Help & Troubleshooting

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.

Mysterious battery drain. Please help! (need PROs)

Intro
Hello I'm a very old lurker in this forum yet a new member and this is my first post so please don't kill me if I failed to follow the rules or if my English sucks. I will try to organize this thread and make it clear and easy to understand and read, while providing as much information as I can.
The Problem
So my i9100 has been having extreme battery drain lately, about 2% per 3 minutes. I refrain from using it throughout the day to help my battery hold until night. When I do so, it is usually about 40% by the time I go to sleep with having BARELY used the phone. Probably just now and then to answer a Whatsapp message or to check the time. I've long ago uninstalled all games since I can't even think of playing games with this horrible battery status.
How it started
The last thing I can remember before starting to have this problem is about a year(?) ago when I was on Jellybam. I had good battery, and then a build with an excellent battery came out and it worked perfectly. I can't remember which version it was, but a little after that, I updated Jellybam and noticed SUPER battery drain. I waited a little for the next updates but it wasn't fixed, so I changed a ROM. I noticed that it wasn't helping. So I tried the following for a couple of months now:
Attempts To Solve The Problem
I have tried the following:
Using lowest screen brightness
Disabling obvious stuff like GPS, Bluetooth, Wifi, 3G
Closing or even NOT installing any known battery consuming apps
NOT using task killers
USING task killers
Underclocking
Removing widgets. Using least icons possible on launcher
Using many different launchers
Changing ROMs, kernels and both
Reverting back to stock
Buying a new battery (extended and not original)
Trying a new original battery from a friend who has i9100
Flashing modems and RILs, including GetRIL. In fact, I've had better battery with worse signal (but not always). I think it was with XXLPH or XXLPW.
Using battery savers like JuiceDefender which basically do everything I've already tried. What's a smartphone without internet
Using BetterBatteryStats and Gsam Battery Monitor Pro. Did not notice anything special (but I am not pro enough to understand everything on BBS, though I googled some of the things and haven't noticed something unusual). Maybe some pro can help me with it.
Assumptions / Notes
A couple of versions ago, I have used Omega ROM version 4.2.1 which suddenly fixed(?!) my battery. I can't remember which build it was, but the new one doesn't fix the battery drain. I assume it could be due to the radio update to XXMS2
I have a feeling that the drain is related to the modem (aka baseband), because I've had some more battery-friendly modems and some less
I have tried many modems that are supposed to work perfectly (and really gave me good connection speed and signal), but they did not fix the battery drain. Even on stock rom
My provider is Golan Telecom, which is supposed to work good with Cellcom modems, but it didn't. At least not battery-wise
Last resort can be taking it to a lab, but it's hard for me to stay without my phone, and I think people here are more skilled than the noobs in the lab.
Can the problem be hardware-related but not battery-related? May it be caused by the huge amount of times I've flashed ROMs and kernels?
Had my phone for around 2 years
Never bricked my phone
Sorry for being a burden to this forum with this first post of mine, but thanks a TON of anyone who can shed some light on this problem for me!
*I have attached one log of BBS
2h screen on , 3h wifi running and 50% how you did that?
I don't think that is a big battery usage

It doesn't look horrendous to me. Things to do though :
1. Grant BBS root rights. Need it to see network and alarms.
2. Did you play music at all? If not, you need to diagnose apps which are putting out sound. Viber is a common culprit.
3. Deleted_wakelocks comes when you turn wifi off. As it's so large, something is killing you when you're on wifi. My guess would be wlan_rx_wakelock. Basically you need to turn off wifi when you're not actively using it to avoid the drain from it. "Better wifi on/off" may be an app which helps you out there, it'll automate the turning of wifi on and off with your screen.

Thanks for your reply.
1. I have given it root rights, and will soon upload an updated log
2. I haven't played music at that time, not that I remember, but even with different players or not players at all, and without sound on keypress, the same drain is occuring. Also, I have long ago stopped using Viber as it eats the battery even more. My battery can't afford to have Viber :/
3. The drain seems to continue with or without wifi. I usually leave my wifi on when I'm at home, like now, but I have also tried, many times, to leave 3G without wifi and see if the battery improves. It didn't, unfortunately.

Huge battery drain when idle

Hello everyone,
My s6 Edge does not go to sleep. It drains huge amount of battery while idle.
I need urgent help. I have disabled all AT&T bloatware. But it still does not work.
I have also tried hard resetting it, it does not work. Battery continues to drain.
Thank You.
Is this something new or has it always been like this? Btw, which version of LP are you on? 5.0.2 or 5.1.1?
Its new, LP v. 5.0.2

5.0.2 seems to be notorious for battery drains...check if your device has the 5.1.1 update which seems to be better in terms of RAM management. Also, are you data or wifi...if on data, then LP is again notorious for a world famous "mobile radio active" bug...it's all over the web...So, the best solution would be to either put the phone in deep freezer until Google fixes the huge bugs in LP or sell your phone...just kidding...
After updating your device (if there's any), do a factory reset...it should solve your problems...hopefully
Does not go to sleep? Check your settings about screen timeout..The battery drain can be fixes through system update..if samsung has any update ready

I hard reseted my phone, disable all bloatwares, haven't installed any apps, haven't signed in to anything (even google, only signed into samsung account). charged to 100%. Left the phone for 4-5 hrs, battery drained to 81%.
fliptroniks said:
I was going to say just make sure you dont have too many apps running and you can also download a battery saving app on the play store for free which can help. It sounds like theres something you have running draining your battery though. Keep in mind however that the galaxy s6 edge when charged to 100 percent can hold a charge for quite awhile, but if your only charging it too around 40 or 50 percent it will die rather quickly.

What does it tell you in the battery stats? That's the first place to look. Is Screen at the top or something else like Google Services or a fitness tracking app? Send a screenshot of that as a starter for 10.

Your best bet is to install TWRP, root, and flash "No deep sleep fix", thats if you dont care about tripping knox of course.
Seems like an aggressive suggestion since we don't know the root cause yet. It might not be a wake lock issue; it could be location tracking or updates getting stuck. I'd rather see the battery stats first.
Screen is not even on the list, i haven't used my device for more than 15-20 mins (used chrome & inbox for 15-20 mins in the morning)

Google Services like I thought. There's a number of things that can cause this as it's quite a fundamental service. The most simple fixes are:
- Make sure there's no pending updates in the Play store. These can work havoc with the battery when waiting for manual approval
- If this doesn't work, remove your google account, reboot and re-add it. For some reason this can fix the sync issues that cause drain
- Still no dice? The next one is to backup, factory format then restore your backup. It's a bit extreme but sometimes when you update your software it causes a glitch that only goes away with a factory format
Each time you try a fix, let the battery fully charge then check the stats a couple of hours later.
Thanks for the suggestion, I will let u know the results soon.

You're welcome. If it's any conciliation I had exactly the same issue and fixed it this morning with those steps.
Google services is one of the biggest battery user but it still doesn't explain his erratic battery loss. I never turn off any features and get decent life.

Tried the third step many times before, didn't work.
So, yesterday I tried the 1st & 2nd step, worked like a charm, I was happy but today, the same results (battery was draning like i was playing games). So I completely removed my google account and left my phone for a few hours. Here is the result (see attached). As you can see no Stupid Google Play Services in the list but what is eating my battery ????

Again, LP has a world famous bug called the "Mobile Radio Active" bug. What this means that if an app uses the data services for some odd reason LP keeps the mobile radio open even if the app does not need it any more...So, for all you know ur issue is Android related and not your device specific. Oh btw, the upcoming M also has this confounded bug...so I believe we will be plagued by this bug for the foreseeable future...And I dumped my iPhone for this buggy Android...Dang!
How is your reception, If most of the time your phone struggle to get reception, it may be part of the problem, just my 2 cents, not an expert, but myself trying to get rid of the google service battery bug...
Better battery stats would give detailed information as to the cause, yet it requires root on all lollipop devices. Helped me find the exact cause of my phone never sleeping

Serious issues with CM13 on Xiaomi Mi4 - please help!

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!
I have been using latest nightly.. No issues no reboot.. Charging time is 3hr

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?

battery drain in idle / no deep sleep / 30% of battery gone overnight

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.

Very poor battery life

I'm getting very poor battery life with my Note 4, which seems to be much worse since a recent update. When I first got the phone a few months ago the battery life was fantastic but now it's almost as bad as my old Moto G2!
I get up in the morning and over a couple of hours spend a bit of time (not constantly for 2 hours) on WiFi checking e-mail, social media, etc. and my battery goes from 100% to 70%. Then I don't use the phone, go out for about an hour listening to Spotify music (offline) using my BT earbuds and when I get home it's down to 40%.
As you can see from the screenshots, it doesn't seem to be the apps I'm using that are draining the battery as "Android system" is responsible for 74% of the battery use. This has maybe 50 packages listed under it, so I think it will be rather hard to identify which one is responsible.
Any ideas what I can do to fix this?
Are you using MTK or SD?

Dont use MIUI, that's a good start. (hopefully you have Snapdragon variant otherwise you're screwed)

I can't remember how to check but I'm 99% sure it's SD. It's mido if that proves anything.
I installed Greenify and hibernated a few things and that's helped a bit, although it's still not brilliant. I also installed Amplify but the results don't mean anything to me, so I've attached some screenshots in case anything stands out (more in next post due to max.4)
Remaining screenshots.

Yeah I've been thinking of changing ROM tbh. Something that annoys me about MIUI is it only allows you to enter a numeric decryption code on boot. I know how to set it to something different than the unlock code and normally use an alpha-numeric code but that's not an option with MIUI as I wouldn't be able to enter it!
I have App Quarantine installed so I was thinking I could try freezing certain system/MIUI apps but if I'm going to change ROM I guess it's not really worth it. The problem I have is choosing a ROM, as there's so many and battery life, whilst important, isn't the only thing that matters to me. The decryption code thing is important, as is full dual-SIM functionality. OTA upgrades is one thing that MIUI has in it's favour and I guess that's not an option with third-party ROMS but upgrades being made available in a way that they can be installed without wiping the phone would be nice, if possible. Dual apps, Second space and Call/SMS blocklist are all quite handy features in MIUI too.

MiracleDROID, give it a go, it's one of the better ROM's i have used on Mido very underrated.
Or OmniROM if you want weekly OTA (Delta updates) just like in MIUI.
And dont expect miracles right after flashing it, give it atleast 1 charging cycle to settle.
Same problem with me .. Battery temperature goes to 41 degree ++ and after night I have to see my low battery
