Extreme battery drain: any way to determine what's causing it?

The last couple of days my battery has been draining ridiculously fast. It just went from 50% to 8%, just sitting in my pocket without otherwise being used, in the last 3 hours. Here's what the battery usage displays:
while unplugged for 3h 3m 24s:
Android OS 81%
Cell standby 10%
Phone idle 4%
Display 3%
Android System 2%
Obviously something is going on with Android OS and I suspect something I've installed is doing this. I have Watchdog installed but it hasn't given me any warnings. Is there some way to determine exactly what is causing the battery drain, other than removing apps one by one?
Thanks!

I've suspected that my display keeps coming on when my phone is in my pocket.
Both the power button, and the trackpad turn on the backlight for 15 seconds when pushed, and it's very easy to do both when the phone is in your pocket.

I stopped using the HTC weather app, there is no way to stop it from constantly searching your location and it kills the battery FAST if you are on the move. Since I stopped using it I have seen 10+ hours of battery life a day and I use it hard, internet, gps, music, twitter.

It's the suspend process.
I can't link it to you cause I'm on the phone but if you look around, you'll be able to find it.

I don't think it's the display because the battery usage isn't showing the display as the main battery usage (unless I'm really using it for a long time). It's definitely something belonging to "Android OS". I wish there was a way to determine specifically what process within "android OS" is to blame. I really don't know much about Android or Linux in general so "android OS" is mostly a mystery to me.
I did uninstall several programs yesterday night and was almost convinced it was behaving better but it looks like after the first hour that Android OS is creeping up and overtaking the battery usage and the battery is draining pretty fast despite not using the phone other than to occasionally check the battery usage. At the current rate I'd be lucky if the phone isn't dead before the end of my workday. It probably doesn't help that I have a rather weak signal at work but if it was increased power to the cellular radio that was the culprit, would it show up under "Android OS" or "Cell standby"? I'd suspect the latter, but maybe Android isn't so logical in how it groups processes....
I'll try removing the HTC weather widgets as suggested and look up the sleep process.
Thanks!

It is the "suspend process" like that other poster said. Here is the defect, you can read through if you like. It's a known problem and not only isolated to mt4g
http://code.google.com/p/android/issues/detail?id=11126

How did people determine it's the "suspend" process? I can't seem to find any way to determine what processes are specifically involved. Is there an app that will tell you that? I am running Watchdog Lite set to alert me at 50% cpu and have never got an alert which makes me question whether my issue is the same one described in that thread. Various people were describing 100% cpu activity by the suspend process and it doesn't seem to be the case with me.
I did have 2 weather widgets on my home screen. I deleted both and since then the problem appears to have gone away. I'll have to wait a while to see if it's truly fixed or just a coincidence. Someone in the suspend thread did mention that plugging into a charger temporarily fixed the issue and I did charge the phone for a while after deleting the widgets so I'm not convinced just yet.
One thing I did notice in the battery usage is that google maps seems to have a significant presence, despite the fact that I haven't used maps at all since last unplugging the phone. What is maps doing in the background? I wonder if it's trying to determine my location and cache map data...
Thanks!

Install Watchdog and in its settings, include, monitor, and display all phone processes.
HTC Glacier running CM7 #15

Enable system process and set thrashold to 30% and you will see the suspend process. Or when you notice the drain is happening go to the phone hidden menu. You know the #*#*3626*#*# in the dialer and then from there go to battery usage then select CPU usage, you will see the suspend process on the top or near the top.

Just use some memory management apps. I currently use ES task manager and in advanced settings, i set it to kill all processes when i power down screen. I never use any battery when phone is unplugged(i literally left my phone unplugged overnight midnight to about 7am and it stood at 73% entire time). And having it rooted, i use SetCPU and set the phone at around 768mhz powersave when i'm not messing with the phone heavily. I easily can squeeze about a day and a half out of the battery.

Is that the correct sequence/code? I put that in and didn't get anything. Is root required?
Sent from my HTC Glacier using XDA App

sorry, that was not the correct sequence at all. I was trying to do it by memory. It is *#*#4636#*#* then select battery history, in the first dropdown box select cpu usage. That menu is pretty useful for other things to like network usage breakdown per app, gps usage, etc.

Thanks for all the info. I particularly like that hidden menu. I had no idea that existed...
Since removing the HTC weather widget my battery drain issue has completely disappeared. The battery now lasts a reasonable amount of time.
Thanks!

Actually I have removed the HTC weather widget couple of days ago and also disabled the water sync in account settings too. That seems to have help with the suspend process on my phone also.

What's the "water" sync? Is that a swype typo for "weather" sync? (Swype errors are annoying in that their usually not so obvious.)
I had also disabled the weather sync (forgot to mention it). Seems to be a lot of little bugs in Sense that need to get fixed.

Why don't you guys do what I did... I have profiles set on setCPU so that when the screen is off the phone runs at 368mhz max and the when the screen is on it'll go up to opp speed... That actually saves alot of battery for me.
Sent from my HTC Glacier using XDA App

Sorry it is weather sync. Yeah keyboard error. I stopped using swype recently for this very reason, but touch input isnt perfect either but still much better for me.

Ya if you are using OC based kernel then use SetCPU to scale your mCPU. Set few profiles for example my max is 1.7ghz, avg is 1.2ghz, min is 768mhz, idle is 368mhz.

Why is my battery life so bad?

ROM: CM9 latest nightly
Kernel: CM9's own
Radio: T-Mobile's UVLC8 (yes, I'm on T-Mobile)
Brightness: Auto (shown in screenshot)
Synced Gmail accounts: 3
Accounts in Email app: 0
My battery drops 20% in 42 minutes, which means it will be depleted in 3.5 hours. And this is mostly due to the screen. Why? I use the phone moderately and ALWAYS press the Power button to turn the screen off whenever I'm done replying to a text or doing anything with it.
Any suggestions?

Well judging from your notification bar you have bluetooth, WiFi, fb sync all on and you aren't even connected to a WiFi network or Bluetooth device. Try turning those off when they are not needed. Also go into the Facebook app and go to settings and change you sync time to a little longer than an hour (if you can stand it). Try that for now and see what happens

Some info on screen on time would help, 3.5hrs screen on time is barely below average. I would expect that if FB is always syncing and blue tooth.
Also I would verify you don't have a wake lock going from charging. You can check with CPU Spy, better battery stats, as well as some others. Cpu spy is likely the easiest way.

Every once in a while I'll get a flash that does this, the battery just seems to be losing its will to live. I don't understand it myself but I restore my last nandroid backup, and then flash again. After that all goes back to normal.

I always keep WiFi and Bluetooth on. I thought neither one of those really used a lot of power unless actually connected. I use BT only in my car and WiFi only at home (evenings). My FB refresh interval is set to 1h. I hardly think this is draining my battery.

Better Battery Stats wasn't free, so I installed CPU Spy and Battery Spy, I am letting the phone charge to 100% and then, I'm going to unplug it and report after about 30 minutes.

Might want to think of picking up some NFC tags and setting profiles so stuff like Bluetooth will automatically turn on when in your car, and off when you leave. And BT and Wifi do drain power when not connected because they are searching for connections.

But wouldn't WiFi and Bluetooth show in the battery usage screen with a high percentage? They would show by themselves or under radio and those aren't high at all. It's all on the screen. That's the problem, it seems. And what I explained earlier is that I don't use it much. I will get a text message, I'll reply and automatically turn the screen off before I set the phone down. I never forget this. I'm actually anal about it. LOL
I just installed Better Battery Stats (thanks for the tip!!!) and will test with all 3 apps as soon as I unplug my phone to go to lunch. I haven't been able to do this yet. Crazy day here at work.
Thanks again.

that's covered under android system I believe. Most important, it causes wake locks that keeps your phone from deep sleeping.

Flash Instigators Kernel with Smartass/Badass scripts (not a joke....)
It will help you tremendously. You must reflash with every nightly update you do.
Sent from my SAMSUNG-SGH-I727 using xda app-developers app

OK, so 4.5 hours and battery discharged 38%. I guess that's not terrible, but my screen was only on for 26 minutes of that time and the phone is reporting 55% of the battery drain came from screen use. I feel battery life could be a lot better just because of this.
What else do these screenshots tell you guys?
I noticed KIK Messenger and MailDroid there. They both sync a lot. I do have a couple of IMAP accounts on MailDroid that I forgot to mention in my OP. But, still, I go back to the fact that most of the drain comes from the screen. These aren't related.

Oh, true!!! I flashed InstigatorX's kernel when I first started flashing the nightlies, but, since I flash them every 2-3 days, I completely forgot to reflash the kernel. OK, it's more like I didn't know it was getting overwritten and I had to reflash it. Thanks for the reminder!!! By the way, do you go with stable (4.0b) or the latest experimental (5.3.2)? Also, do you just flash the kernel? What are those scripts and what do you do with them? I did not understand his instructions. Maybe I should be asking there, but since I already have you here...

For one, turn your screen brightness down. I use auto-brightness and never have a problem seeing it, and my battery drain is ok that way.
Two, you've got the AudioOut_1 wakelock. Turn off system sounds in the settings menu (keytones, touch sound, screen lock sound, vibrate on screen tap) and that will take care of that.
Any type of instant messenger service (Skype is well-known for doing this) will wakelock your phone while it searches for IMs. No way around it other than an uninstall. You can't control IMAP pushing, but you can control folder polling, which eats up a lot of battery. I'd set your MailDroid accounts to not poll folders automatically more than once a day.
And definitely turn Bluetooth off when you're not actively connected to something. You might as well be using your phone as a flashlight with how much power BT burns through.

I am currently on RC2. I went to the 21/22 nightly but was not liking how it was behaving so I went with the RC for now.
In INSTIGATORS forum you will see in the links to the kernel one that says <-------- works with RC2.
I used that one and I am happy. Sure you could do the newer ones but I am happy where I am at currently.
Just boot into recovery and install from zip.
(Assume u download the zip on your phone....)
Its easy as pie!
You can play with the settings if you want but the default settings work pretty freaking good!
I would for sure recommend going to that forum as Instigator himself can answer ALL your questions in depth.... I am merely a messenger and user of his kernel.... wish they would just merge it into the cm9....

Screen brightness: I use auto as well. It's in one of my first screenshots in this thread.
AudioOut_1 wakelock: Done. Thanks. I'm going to miss the touch and screen lock sounds. LOL I left dial pad touch tones and volume rocker music controls in that same secton checked, by the way.
MailDroid: I went through all the settings, both general and for the e-mail accounts and couldn't find a place to specify folder polling interval. Do you have it installed? If so, could you tell me exactly where to find this please?
Bluetooth: I'll try my best to turn it on only when I needed. I could also follow dakpluto's suggestion with the NFC tags. But then, I'd have to leave NFC on. Doesn't that drain battery too?
And you see, although all of these will help, don't you agree based on my screenshots that the biggest offender here is the screen and this is the area I should really be looking at?

Here's what I just did:
1) Installed latest (7/23) CM9 nightly.
2) Installed InstigatorX's 5.3.2 experimental kernel using CWM.
3) Installed InstigatorX's BadAss script using CWM on top of the kernel (I guess that's how you do it).
I will see how my battery behaves. It'll be difficult to know which of the many things I did is the one that yielded the biggest improvement, however. Oh well.
Thank you all!

Yep I have power saving stuff such as turn off wifi when idle, I dont have GPS on 24/7 and I dont have wakelocks, I also set mine to use 3G/4G rather than LTE. If it was a solid blue that means something will be constantly on draining the battery.

For performance I prefer smartassv2 for power saving I would go for badass governor. With badass it doesn't jump clocks to max but goes by phases thus not aggressive and doesn't eat a lot. Test them out read the change log to see if changes pertain to you :good:

Troubleshooting cpu usage

This great forum is full of information but for some reason whenever I tried searching the cat reading the book pops up and says its taking a long time so I figure I will try to ask here. is there a app that will basically keep track of which apps use the most cpu, ram or resources in general? I am trying to figure out which of my 100 or so apps installed is using the cpu the most so I can possibly find an alternative. I just installed the custom kernel from this page http://forum.xda-developers.com/showthread.php?t=2129218 and it did seem to make the phone faster but the battery usage is still the same. Another question I have is if it is really necessary to run antivirus software on the phone? Doesn't google have something to check for bad apps in google play?

DroidWall
Install DroidWall. Block network access to any app that does not require network access - cameras, video players, calendar, minibooks, text readers, galleries, soundboards, music players.
Lots of these apps like to wake themselves up (even if you don't use them), search your phone for data then transfer data over the internet. That all uses CPU and kills the battery. If they wake up and find no network connection they shut themselves down again. Block them and you are guaranteed 20% or better battery life.

What is your camera? Can you post the Google Play link here?
Also, turn off Background Data, turn off Auto sync, and do not let your apps update automatically. That also drains the battery.
I can get 2½ days on standby on my G2X. I'm running the last CM7 nightly and Trinity T15-G2x-06022012 kernel.
I can get better battery life with Maz's kernels but I was getting overheating and SOD.

My camera is the one that came with CM7 and does not have a Play link. I would like to keep the auto sync on and data as I like to have some stuff updated like weather but would like to know how to stop the facebook app from doing updates because I really don't care about them and see that facebook seems to be a top cpu user for me. I installed an app called Battery Drain Analyser (play.google.com/store/apps/details?id=com.msd.battery.indicator&feature=search_result) and it seems to help me find out what is sucking up my battery. I would like to keep the facebook app but not have it fetch updates constantly. I know I can firewall it but that would require me to constantly edit the firewall rules every time I want to use the app. The same thing goes for some other apps that self update like twitter. If there was a way to turn off background updating of these apps like facebook and twitter and keep on the updating when i start the apps myself.

Well, the camera that came with CM7 doesn't need network access.
But if you are keeping background data on and auto sync on, and you are running the Facebook app, put that all together and that's a battery **** sandwich. You are deliberately giving yourself poor battery life.
For me, I don't need to have the weather CONSTANTLY updated when I'm not looking at it, I just click the Weather app and I see the weather. I'm not that obsessed with the weather to have it update when I'm not looking at it.
My guess is if you took my advice you'd double your battery life, but there you have it.

I knew about turning data off and auto sync long time ago. Also bluetooth and wifi turning off will help.but the apps that are running all the time downloading data in the background are the real problem and cant be configured not to do that are complete crap. and the newest facebook app also without my permission tells me about missed phone calls! I already have a build in CM7 feature that does this! why would anyone need this? I am willing to bet that every android phone has some type of way to show you that you missed a call. I think its all about advertising. The little F shows up on the status bar on top now along side my missed call icon when I have a missed call. This crap started when they pushed the new version a few days ago.

I will give this app a try. Seems like it makes sense. Thanks.

AudioMix Wakelock on CM11S

I'm using a OnePlus One with CM11S, and have been experiencing wakelocks from AudioMix, both on stock kernel and on franco's kernel.
Wakelock Detector says it's from the "1013" process, which I'm not sure what it is (seems to be a system process though).
The wakelocks are pretty long, currently for example I'm on 83% battery with AudioMix wakelocks of 20m43s, which is about 13% of the time the device has been unplugged (not to mentioned when the screen was off, which is only part of that time).
I have no clue where this might be coming from or how to stop it, and would appreciate any help on this.

Bump.

I'm having the same issue on my HTC one m8 can not find the issue

You can track the process down using the /proc folder... Just use ES File Explorer and go to /proc/1013/cmdline while the process is still running with that number. That should tell you the command that started the process.

Nevermind... Won't work for system processes, just for user processes...

Actually, there's no such folder as "1013" in /proc.
I did find a "1013" folder in /proc/uid_stat/ but it only has two files in it:
- tcp_rcv
- tcp_snd

Then the process stopped already... The /proc folder is an own file system in linux (which Android is based on), it shows realtime values...

That's odd, since I keep seeing that AudioMix (which is under 1013) is getting more and more wakelocks every now and then when I check in WakelockDetector.
Any suggestions maybe? It's adding up by the second (even if the screen is on and I refresh the wakelock counter goes up).

definitely suffering from this same exact Wakelock also. Still haven't been able to pin down the culprit...working on it though hopefully I'll find it.

I believe the audiomix wakelock is music; been playing music with the screen of or using syncing services?

Only while charging.
Also, the wakelock counter for AudioMix keeps going up by the second, even when the screen is on (and whilst I'm not listening to music), so I'm not sure it's that (or at least, that's not all it does).
As for syncing services, what do you mean? Like Dropbox sync? Or Google sync?
My Google account is synced across devices (obviously), and I do have Dropbox uploading my phone's camera photos, but I didn't take any new pictures lately. When I do see it's uploading photos, there's another wakelock (I can't remember its name exactly, but it contains "Dropbox" in the name, so that would be easy to identify, and also makes sense to have it keeping the device awake when uploading photos).

same problem here....

Uncheck touch sounds and screen lock sound in settings. It for me fixed the problem.

I just tried it for about a day and a half, but it didn't fix it. Still getting about 30-50 minutes of wakelocks from AudioMix per charge.

I'm also facing this issue. Do you guys use PowerAMP to listen to music? I don't know why I think at PowerAMP, but I've had this issue also with my old Nexus 5 (now I'm on a OnePlus ONE), and NEVER found a solution. I really don't know what to do. That's even more strange thinking that some days ago I did not noticed this problem, now apparently random it started draining battery..
Ok just tried with some basic tests:
tried disabling sound at pressure on screen and lockscreen sound, checking with BBB it seems it's stopped now. Also it seems to stop using vibration instead sounds. Every time the phone emits a sound (coming from a pressure on the screen, such as the BBB refresh button, or any other sound) this wakelock happens for about 3-4 seconds, then, keeping refreshing BBB statistics it seems to stop. With vibration mode and without sound at pressure on screen this wakelock seems to be ok. But if I turn on the sound checking every checkbox in Audio settings, every time I refresh with BBB the phone emits a sound, and in fact this wakelock never ends and keeps going.
Now what I'm asking is why this happens randomly to someone and why some others don't face this problem. Also because for me started 2-3 days ago, but I always checked every checkbox in Audio Settings.

having this problem too, its waking my device a hell of a lot.

I use PowerAMP as well, but AudioMix is keeping my device awake even on days where I don't use PowerAMP at all. However, it might have a service running in the background, so it may still be it.
I'll have to try and freeze it and give another player a try to see if this stops.

[Root] The incredible guide to incredible battery [Permissive kernel and Xposed]

The guide to get incredible battery on your S7E!​
A lot of people are having trouble to push the 3600mah battery to the absolute max, so I will here show you how to do so. This will mainly be a link to another post made my @v7, which have made an incredible guide to get a good idle drain. I will mainly explain what works on our S7E and what not, while giving a few other tips. Most of these tips can be found all over the internet, but I just want one thread, where they're all collected, so people can read every tip in one thread. As most guides are general through out all devices, they is what works and what don't on our devices. You're free to share your own tips!
REMEMBER TO MAKE A NANDROID BACKUP. ANYTHING YOU DO ARE NOT MY FAULT NOR ANYONE ELSE BUT YOUR OWN FOR MAKING THIS CHANGES!
Firstly, use a debloated rom.. That do a lot..
As said, @v7 have made this guide here. Remember to thank him!
Greenify:
Get the donation package and greenify everything that runs in the background and you don't need push notifications with. With the Shallow Hibernation, it still runs nice and smoothly when you open them. After that, you enable GCM push for hibernated apps and look, if any of the apps that you need push notifications for, supports GCM push and if they do, hibernate them. You will still get notifications, but remember to check "Do not delete notifications from hibernated apps".
I have almost everything hibernated - Maps, Facebook Messenger etc, when still working smoothly - besides Play Store, as that gives problem with paid app licenses. I also enabled Aggressive Doze. You should whitelist the same as in Powernap, that will be listed below here.
Amplify:
I have everything in mentioned in the thread Amplified without problems. I hadn't touched the services, but they should be save to disable anyways. Network Location service, have given me problems with Android Wear communication before.
Powernap:
Here comes where you need a permissive kernel. The SuperKernel that just came out, is the only one on XDA for now. In Powernap you should whitelist the following
Amplify
Android System
Google Account Manager
Google Play-Services
Google Services Framework
Greenify + Donation package
Apps you need push notifications from (like Facebook Messenger)
Xposed Installer
Your alarm clock
Basically, you should whitelist anything that you want to run in the background while the screen is off.
Better Battery Stats:
Check the app after a sleep, but leave everything on as if you were using the phone (data, bluetooth etc) as this is about lowering power usage on normal use and not seeing how long standby time you can get while everything is turned off. GCM_Reconnect and Heartbeat might be high for Google Play-Services, but for me, limiting them gave late or non push-notifications, but test it yourself (remember to restart after limiting/unlimiting).
All the small things:
Turn off location history
Turn off services you don't need and let Tasker control it. (Turn GPS on when maps open, hibernate and turn maps of when closed etc)
Turn off bluetooth and wifi scan all the time
Get Smart Network from Xposed and set your network to Edge when screen is off and 3g/4g when screen is on.
A dark theme with dark icons can save quite some power
Samsungs own greyscale can be enabled in accesibility and then triple tab on homebutton, when you know you're out for a long day.
UPSM Manager from the Play Store can add apps to the Ultra Power Saving Mode, so you can add apps like Facebook Messenger and suddenly it's way more useable.
Use Tasker to force sync, instead of having it activated. I force sync every 2 hours with Tasker + Synker
I have turned off features that I DO NOT USE. Under Advanced Functions, almost anything + edge screen features.
More connection settings and "always search for devices" - Off
Custom kernel settings:
There are no custom kernel out on XDA yet that supports full Synapse, but the Echoe Team have successfully build one.
I have set both governors to conservative, which actually is impressive smooth, while it should be the most battery saving governor which don't lag (like Powersave).
The I/O schedulers should be set to noop which have quite good battery life, without limiting performance too much. I haven't felt a difference yet.
TCP Congestion is set to Westwood (but I think that is standard anyways).
Everything have been undervolted by 25mV. That is nothing from a battery saving perspective, but well, i'm still testing.
L Speed from @Paget96 (thank him!) here is quite nice too!
I haven't had any lags with these battery saving options yet. Everything not mentioned is just standard.
OOM Killer - Enabled
Cache Reclaiming - Minimum
Kernel Tweaks - Light
Kernel sleepers optimization - On
Battery improvement - on
Wifi sleeper - On
Flag Tuner - On (Some people on S7E have mentioned problems with this.. Lag, reboots and bootloops, but I haven't had any problems).
IO Boost - On
I have power saving mode enabled, with background data enabled and my phone is still butter smooth, Also, check for apps to add in the battery saving menu, as I have enabled some apps I don't use or need notifications from, manually.
I get around 5-6 hours SOT where 3-4 of them are Clash Royale, if not more.... Yeah, I game quite a lot.
I think that was all for now, but I will keep it updated when I get new ideas to push it to the limit.
This is still keeping the phone "smart", as you adjusts it for your needs.. Inb4 all the people saying, why buy a smartphone if you disable every feature.

hmm that would kill performance in tekken and AB2 as those games are heavy on QHD but i try it nonetheless, ty.

Of course ?

Good guide,
But why are you mentioning a kernel none of us have access to???

There are two kernels on here now.
You could ask for permission to get on the forum where the kernel is or you could simply wait. I knew it would only be a question about days, before there would be kernels on XDA too.

With all this stuff I might as well activate ultra power saving mode and let it be

Why if I may ask? That makes your phone way more restricted than the above do.

Exactly.
I've gone through a lot of these kinds of tweaks in the past, and generally found having to re-load apps and disable features I like having wasn't worth the small battery life increase I saw.
That said, Everyone uses their device differently though, so what doesn't work for me may work well for others. Remember that before you say I'm spouting nonsense about small battery life increases.

I certainly agree that it depends how you use your phone. But if you only rely on a few apps when display is off, like a few messaging apps, Power Nap can certainly increase your battery life. I have a idle drain around 0.0-0.2% (note, 0.0% is not the same as zero drain.) and I still receive messages, and Tasker turn everything on that I need when I need it (GPS, nfc, sync and so on). So if you just install the apps, yes it decreases functionality a lot, but by tweaking it to exactly match your usage and not limiting what you use, you can certainly get increase battery life without losing features. I use my phone the same way now as uprooted, not limiting anything I use..
Most people have a lot running in the background they don't really need or depend on or that can wait till the screen turns on.
