Battery is dying at fast rate

For the past 3 days my battery is dropping at an incredibly fast rate. Even if its idle it will drop about 20 % every half hour with little to no use. I rooted my phone and am now running fresh with kings kernel but no change. I an even dropping in airplane mode. What can it be? I left it at 90% connected to wifi with the sync off and when I woke up 6 hours later it was at 20%. Any solutions?

Sounds like mine, just turning on the screen drops the batter 1-2%.

Hit menu and click on settings. From there, go to About Phone and then to Battery. Note the awake time and turn the screen off for thirty seconds or so. Turn the screen back on and check the awake time again. If it's not within five to ten seconds of the time you noted before you turned the screen off, something is keeping your phone awake, which does a number on the battery.

square parts or system panel might give a better idea of what specifically is draining your battery, or preventing it from sleeping correctly.

It seems fine, about 15 seconds difference. The weird thing is this only started happening about 3 days ago, I rooted yesterday, and its still doing it.

Go for what Fachadick said. Download and install Spare Parts from the Android Market. Go to Battery History and click on the dropdown box where it says "other usage" and click on "partial wake usage". If anything is taking up one of those bars, that's your problem.
If there's nothing notable there, it could be damn near any of your applications. When you root, you lose settings for you apps (depending on how you rooted), so your autosyncs could be going crazy. Might wanna check those.

What he said Rooting won't fix battery issues. Rooting and installing a new ROM is just like reinstalling your OS. It can fix things or not depending on how it is configured. Likewise it won't fix your phone if hardware is bad.
does it drop steadily or just the first 5-10% or so? There is a well documented issue where the trickle charge stops at 100% and then shuts off so the phone actually drains a bit before it kicks in again. When you first unplug it, the reading may drop quickly until it reaches the real level.
Likewise depending on what you have installed and how it is set up, there may be something keeping your phone from sleeping. Check for partial wake use like the previous poster said and that will tell you what process/application is keeping your phone awake and draining battery.

i had this same problem about the battery before i rooted my phone. after i rooted it i got overclock widget and i get through the day with so much more battery left. i make sure my battery is full right before i go to bed, i put it on airplane mode and go to bed wake up around 7 a.m.(my battery is always at 98 when i get up in the morning so 2% in about 8 hrs) and i get home around 8:30 and my battery is at 48%. and no i dont leave it lying around with the screen off. i constantly go on, text, internet etc.
hope it works for you too!
your friend.

I am having this same problem and it started about 2 days ago. I downloaded Spare parts and looked up the partial usage (screenshots attached). I'm not sure what I'm suppose to determine from this. Mail is showing with more fill-in than any other program, when I click on it, I get the details. Can someone help?

It doesn't appear (to me anyway) that you're having any issues with partial wake time. You may have a runaway app draining your battery and cpu - system panel is invaluable for hunting those down. It will show you each running process with exacly how much cpu it's used. It gets even better and gives evenmore detail if you let it monitor your system over time.

There I go, letting my prejudices get ahead of me again, sorry about that. I think in the market it’s called systempanel – one word.

So will the free version pinpoint the problem, or would I need to do the paid version?

to be honest, I'm not sure - I don't remember what kind of detail it gives you in the free version, but the app is so useful to monitor cpu and battery, as well as for hunting down rougue apps, I would recommend the paid version as a "required" app for all rooters.
when you load it up, the default screen is essentially a taskkiller - but more importantly, you can go into settings and have it show ALL processes, and if you select one of the apps or processes from that main screen, it tells you when it was started, how much cpu it used, how much memory its used, and at least in the paid version, a historical graph of cpu usage - so you can see exactly when it used the cpu over the past 2 hours, 8 hours, 1 day, 3 days, or over the past week.

This is also happening to me from 4 days ago. I haven't installed any new apps in the last 15 days or so, and for good measure, i uninstalled the last 10 apps i installed before that. When i check battery usage, the "Android System" takes up between 60 and 70 percent. When i open it, it lists like this:

Bluetooth is off, 4g is off (when's cincinnati going live already!??! Just the heart of downtown and the mall)
Wifi is off, and I've been turning off gps now, but i always used to leave it on and made it through the day.
"Cell Standby" is next with 8%, everything else below that.
I kill everything with task manager now and it doesn't seem to help at all.
It is not possible to exaggerate how fast the battery is being drained. It drops by 1-2% each 45 seconds or so. I've done the Charge-for-8-hours-turn-off-charge-trickle-charge-unplug-trickle-charge-unplug-etc thing last night and no help. This is with no widgets installed, no live wallpaper, no music, when for months i can make it through the day with a little pandora, bluetooth while driving, a game or two, internet, maps, and several other apps throughout the day. I've stopped everything but messaging and phone calls and it still drains just as fast.
PLEASE HELP!

I don't know if this applies to anyone in this thread, but after installing a new rom sometimes I forget that the Gtalk/Gchat app resets itself to automatically sign in, and drains the battery while running in the background.
Changing it to not run automatically helps out for me, although I feel that I may have gotten slightly better battery life out of the rooted stock rom than running the King kernel I'm using right now. At least in terms of percentage drop. I never really reset my battery stats or recalibrate after installing a new rom, don't know how much that has an effect on the readings.

This is turning into a deal breaker
Its not latitude, off. Not ANYTHING as it still happens with everything off and all apps killed in task manager.
No background, no live wallpaper (even though i used to have one all day). No music (even though i used to have pandora on a couple hours a day). screen brightness is always low (even though i used to leave it above medium, and would turn it up to high to watch video or a game, and still made it most of the day before).
The phone's battery use thing swears its "Android System" thats taking by far the most, not even cell standby got larger when i unplugged it in the basement where there's no service.
i've turned off everything i could think of, no apps 'auto update' and i've put all syncing and updating and stuff to manual or off that i could find.
I don't think its a faulty battery because it is ridiculously noticeable that something has changed in that ANDROID SYSTEM is now a power hog. Why and what do to?????

bam_dmux_wakelock - What is it? How do we stop it?

How to check: Install BetterBatteryStats and then check Kernel Wakelocks.
It seems bam_dmux_wakelock has something to do with mobile data. It's sort of the equivalent of the wlan_rx wakelock which is for keeping the WiFi signal active when the screen is off. I've tested and verified that if you turn on wi-fi and use that, bam_dmux_wakelock stops happening (since now wlan_rx wakelock is there) but the moment you turn off wi-fi the bam_dmux_wakelock starts going.
What's odd is I've had my phone off the charger for 6 hours but yet the bam_dmux_wakelock has only been running for about an hour...the only thing that seems to coincide with this is using Bluetooth to stream audio (although I did that earlier without issue too!).
I'll post a screenshot below as an example but I'm hoping by finding others with this problem we can find root cause and fix it!
Thanks.
What is known:
- It is related to 3G/LTE radio and not wifi
- Turning the phone's airplane mode on stops bam_dmux_wakelock from occurring. Turning Airplane mode off and when data connects, bam_dmux_wakelock starts again.
- Turning Wifi on stops bam_dmux_wakelock from occurring
- Rebooting the phone DOES NOT STOP bam_dmux_wakelock from occurring without uninstalling any apps or changing anything. So this is present at boot-up.

I have noticed this also. It have tied it to Bluetooth in my car. When I paired my S3 with my car it asked me if I wanted to let the car download my address book. I said yes but did not check the "Remember this choice". So the next time I got in and it asked I told it no and then checked the remember box. From what I can tell this was causing my car to keep asking my phone for the address book over and over. I have since redid the paring and allow the address book to sync each time I get in the car and this as stopped this wake lock for me so far. It has helped my batt also. When I was in the car the battery was dropping fast. Now it does not. Next time it happens try tuning off BT and see if it stops.

Thought it was Bluetooth too but turning it off has no impact on this.

I think BAM is Bluetooth something. So I think it is tied to BT. But as I think about it that does follow mine also. Once it started which was each time I got in my car it would not stop the battery drain unless I rebooted. Even if I did not use the car. So the way I see it once you trip it there is no stopping it unless you reboot. But that be different than what you are seeing.

See the problem with that is even after a reboot it starts and runs a little although not constantly without even connecting BT. If we at least knew what it stood for it would make it easier to troubleshoot. Also if it's Bluetooth it doesn't make sense for it to stop when you switch to wifi. It has to do with the mobile radio and mobile data for sure

Ok so doing some more playing and my latest guess is the firmware update. So I went in and tried to check for an update date just for the heck of it. Right after that I started to notice the phone being just a bit warm. Then an hour or so later I could see the battery was dropping. Bam waitlock was there also. I did 2 things and one of them stopped it. I flipped air plane mode on and off and the turned mobile data off and on. The mobile data one I read in another thread that stopped it. Once I did that phone cooled and battery decline stopped. Now when I do a check for an update I get an error that it can not reach the server and it will try again in 48 hours. That seems strange to me. Every other android phone I have owned will say something along the lines like " your software is up to date" or something like that. So I am wondering if this starts when the phone tries to check for an update and can not reach the server and keeps trying or something that keeps the radio alive. See if you can recreate it. I will be watching mine.

Yeah definitely not Bluetooth - haven't used Bluetooth (has been off) and I've been getting bam_dmux wakelock. I think it has to do with keeping the mobile radio active so the phone can send/receive data. Have you tried turning off autosync and seeing if that makes it stop? I have a feeling similar to keeping Wifi awake, this wakelock keeps the radio awake so the phone can receive data. I bet the less stuff you have running that's waiting for updates the better!

My guess is we will need a firmware update to fix this. It is either something deep in the radio or internal processes since we can not really see it in any tool.

I know it's a bit of an old thread, but has there been any progress made discovering what this is? I've been trying to tackle my battery usage issues and this is one of my big sleep wake offenders.

I'd also like to know this...

Add me to the list of people who cant figure out what is causing this wakelock. There is very little info about it on the internet.

I just made a discovery - I had recently installed Google Tracks and played with it a bit. Shortly after that is when I started noticing the bam_dmux_wakelock. It finally clicked today that Tracks could be the culprit. So I saved the tracks I had created, uninstalled, and no more bam_dmux_wakelock! Well, that's not entirely true - it's still there, but instead of being *hours* of usage it's down to seconds.
Does anyone else who has noticed this have Tracks installed? If so, will you try uninstalling it to see if you have the same results I did?

I think you are on to something. I noticed my Google maps had its location settings turned on for Latitude. So my phone was tracking me and uploading my location. I turned this off and of course battery was much better but all most no bam_wakelock. Check and see if this is turned on by going to maps then Location Settings. Turn them all off. Unless you want your friends to be able to track you.

BAM dmux is for mobile data so anything that keeps mobile data connection open it will show up. Stands for broadband access multiplier demultiplier. It's normal.
Just means something is keeping data connection alive. I did more research.

Thanx for the explanation. I'm gonna try to find the culprit then.

A combination of uninstalling Tracks and disabling the Google auto-backup solved my battery drain problem. Took a reboot after turning off backup before I really saw a difference, though.
My bam_dmux_wakelock is still there, but nowhere near the level it was before. And after reading the above explanation that makes sense.

For me disabling the auto starts from Google Maps and using tasker to schedule Google sync instead of using auto sync has made a world of difference.

Thats normal behavior, if u click stay away then plug it in then unplug then plug back in you will notice its also unchecked again [least it shuld be]
This is because you dont want ur screen to stay on like that always right, lol.
Now that being said, there is an option under display to keep the screen on as long as your looking at it. [Face must be detected by cammera]

The check box is for "stay awake while charging"

Yes that should he commen knowlede, thats the stay awake under developer options. thats why I was discussing the charging situation of checking the box, pluing your phone in, then unpluging n plutlging back in qnd the box will uncheck. This guy appaerntly wants his phone to stay awake regardless of that, hence the stay awake while looking at device option I mentioned. Which is in screen settings.
Note the two diffrent settings menus quted, hope this clears up any confusion.

I too find this very frustrating. I turn on Stay Awake and have to keep turning it on. And as this is my 3rd Android phone and have often used nightlies I know that it doesnt HAVE to turn off. On my Defy I had Stay Awake selected and no timeout set for the screen and was quite happy. I use my phone in my car as a GPS and expect the damn thing to stay on, and do not want to have to swipe the pattern every 10 minutes, which is the longest timeout on the stock ROM.

Gps should keep your screen on regardless of settings, use google navigation. Works that way for me at least. N thats without stay awake while charging or stay awake while looking ticked
Sent from my SGH-T889 using Tapatalk 2

I want my Note to ALWAYS stay awake on WHEN CHARGING which is what that specific feature is supposed to do. Plugging/unplugging does NOT disable the feature for me, only rebooting. It should stay enabled. The feature is ONLY meant to keep it awake when it is being charged.
Also, anyone knpw if there is a way to prevent the screen from DIMMING when "stay on while charging" is working (or any time the screen is on for that matter)?

Maybe it's to prevent the screen from burn-in (although it'll probably still happen eventually.) My galaxy nexus had burn-in after months of usage.

It's intent is to be a DEVELOPERS option (hence the developers menu item) and not a USER option so my guess is that is why it does not survive a reboot.

Stay Awake While Looking at Device is not sufficient for all situations. For instance, if you need Google Maps to keep up with the latest traffic conditions during your commute, you definitely do not want the screen to shut down if you haven't looked at the screen for a while.
Unplugging the USB cable or charger has nothing to do with the Stay Awake While Charging setting in the Developer Options section. I have unplugged and replugged my phone several times after ticking the Stay Awake While Charging box, and the setting never changes, not even after rebooting.
Even at that, my screen still shuts off after a certain amount of inactivity - but when I turn it back on, there's a message saying the phone is charging on the lock screen.

Google navigation stays awake on my phone even without stay awake while charging. If its ticked I have never had it turn off except sometimes when unpluging n plugging back in, this may be rom specific.

I was having the same problem as the OP until yesterday.
Download "StayAwake" for free from the Play store. Simple program with two options - stay awake at all times, and stay awake when charging.
This program in particular works better for me than "Stay Awake" in the Dev options for an important reason: it can keep the screen awake while UNLOCKED and plugged in, but if the phone is locked and I receive a notification that wakes it up, the screen will turn off after a few seconds like normal.
So: If I'm using in the car and want to keep my music player/maps/whatever visible, it does that. BUT if I'm sleeping and charging the phone and I get a text message that turns the screen on, the screen won't stay on all night long and heavily slow down my charge time like it would with the Dev option.
As an iPhone user this is the functionality I was used to and this software does it very easily.

StayAwake works great!

YAY! This worked exactly as you described. Now Google Maps or whatever else I need stays on and the phone unlocked while driving.
I think it's interesting that we need apps like this to recover functionality that I had on other phones. Another example is the USB storage mode, I had to download "Easy UMS" to be able to access the SD card properly.

I was having this problem too, actually still am. Those custom apps are one way I suppose, but I think this is actually a bug since it has intermittent results. Sometimes it stay's awake, sometimes it doesn't. I have never been able to put my finger on exactly what is causing it, probably because it's nothing I have access to.
I'll try the app, last time I did there was a bit of a caveat.
And for the record, if there is some kind of screen burn in saver with my phone, it is the first time after owning several versions of varying android phones, so it is a 'new' option that contradicts it's own description, so I'm not convinced.

Sudden battery drain - how to tell what caused it?

My Zenwatch usually consumes <50% of its battery during a typical day. Today however it was completely dead by 7pm, even though there was nothing unusual about the day - it was worn at the same location all day, and was in close proximity to my phone all day.
Is there any way of tracing what causes this sort of sudden battery drain?

Hello,
same Problem here.
You can use the "Android Wear" app, connect to your watch and press the gear wheel on the upper right, then press on the first entry " Asus Zenwatch 2" and then you see the option "Battery of the watch" in the middled of the screen. It looks the same as you can see it on the telephone but for you watch battery.
I made a few screenshots today:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
looks ok for me...
still ok...
now there has something started sucking the battery empty....
now it has stopped... but only for a moment - later it came back and at 15:30 I had only 13% left. I noticed that the temperature display still was showing 7°C but my car display shows 16".
I restarted the watch now and voilá the temp changed to 16°... very stange
And this is the second watch - the first one I send back to Amazon because of the same "bug" ....

For some reason I can't see any of your screenshots. Any chance or re-uploading them?

better now?

Still nothing

I think he was trying to upload a screenshot like the one I attached to this post, it's basically a similar battery usage indicator like the one for the Android phone itself. I don't have anything on here really, yet, because it hasn't been too long since I took it off the charger.

Asus Zentalk forum has walkthroughs
The Asus ZenTalk forum has a walk-through with pictures on how to get to the battery use screen. (I'd post the link for you, but I don't have enough posts yet to post links).

I just had the same problem happen this evening. Everything was fine until about 8pm, with 70% remaining, then two hours later it had plummeted to 15%. I checked the battery stats in the Android Wear app, as suggested, but they didn't help: there were only 2 lines:
- Watch Idle: 5%
- Screen: 2%

That is a pretty drastic and sudden drop. What watch face were you using? Did the watch do (vibrate?) or alert you to anything (view messages, receive a call, etc) during that time?
What are each of your settings in the settings area (what features do you have turned on or off)? If you have wifi turned on where you in an area where it may have been attempting to connect to nearby wifi networks and repeatedly failing (like trying to connect to networks where there are sign-on pages where you have to agree to a user agreement before connecting to a free wifi network)?
If you look at your phone battery usage during that same time (if you still can) does it show anything highly active on your phone during that time? (For example could the phone have been trying to update any of the files or apps on your watch during that time?).

To answer your questions:
- What watch face were you using? Perfection (although the last time I had this problem I was using the Explorer watchface)
- Did the watch do (vibrate?) or alert you to anything (view messages, receive a call, etc) during that time? No - I just got a few notifications when emails came in
- What are each of your settings in the settings area?
- Brightness: 3
- Font size: Normal
- Always on screen: Off
- Wrist gestures: On
- Screen lock: Off
- If you have wifi turned on where you in an area where it may have been attempting to connect to nearby wifi networks and repeatedly failing - No, I was at
home in my study and lounge (within 15 feet of my wifi router at all times)
- If you look at your phone battery usage during that same time (if you still can) does it show anything highly active on your phone during that time? I don't have the ability to look at yesterday's phone battery stats, but I know that there were no app updates or unusual notifications on the phone during that period yesterday

In the days that have followed did the problem of sudden drain continue to occur, or does it appear to have been an isolated incident?
In that time period it experienced the drastic drop were you doing anything repeatedly? (ex: eating food, exercising, reading a book?) Repetitive tasks where you wrist was moving a lot may have been turning on your watch using the wrist gestures, and it seems that wrist gestures (where the brightness level 3, color, etc are activated) may use more battery than always on in its timed-out dim mode does. If you're continuing to experience the problem try going a day with always on screen turned on, wrist gestures turned off, and see if there is a difference in your battery use at the end of the day.
Your watch may also be preforming syncing with your phone at a particular time, and transfer of data across wifi between the two may be draining the battery. You could try turning off the sync setting on your phone for a day, and see if that makes a difference.
Finally you can try turning off wifi, and see how much longer your battery lasts with wifi switched off on the watch.

In the period when it dropped drastically I was sitting on the sofa watching TV. There were no repetitive tasks. In fact I could probably not have been less mobile!
I now have "always on" mode enabled, and have disabled tilt-to-wake. So far it has maintained the usual (low) battery usage, so I'll wait and see if I get a recurrence of the problem.
The problem with turning off sync for a day is that it's unlikely to prove anything. This problem only happens every few weeks, so if it doesn't happen on the day that I have sync turned off then I'll be no wiser.
I'm not sure what you mean by turning off wifi on the watch - do you mean putting it into airplane mode? If I do I would fully expect my battery life to improve, but how would that prove whether it was the potential cause of the rapid 2-hour drain?
I'm watching my watch battery levels very closely at the moment, but if I do notice a sudden drain again what can I do to establish exactly what is happening on the watch at the time? If the watchface is displayed as usual, and there's no evidence of any specific app running on the watch, what other options do I have for finding the cause of the excess battery drain?

After 4 weeks I've just had the same problem on 2 consecutive days. At the end of the first day I notiiced that the "tilt-to-wake" option had become re-enabled (I'm not sure how, as I don't remember enabling it). I disabled it again last night, but today my battery was pretty much dead by 9pm. I tried a reboot earlier in the day, but it didn't seem to help.
The latest version of the Android Wear app seems to have removed all info on battery usage, so this is impossible to diagnose. As things stand, the watch has gone from being an all-day device to a device that won't last a whole day in the last days (

Rather than trouble shooting you should just go for a completely new set up of the watch. Uninstall the wear and ZenWatch manager apps, factory reset the watch and reinstall everything.
I've gone from just under a day to an insane 3-4 days battery life. (I don't use any fitness trackers or ambient mode btw)

So today the problem seems to have gone away. For the first time since the weekend I got through the whole day with only 40% battery usage. This battery drain issue seems completely random, and it's annoying that there's no way of diagnosing it.
Surprised that more people aren't seeing this.

The new version of Wear from yesterday has the battery usage option again.

Ah OK I'm still on 1.4.0.2462440.gms and the Play Store isn't showing an update available yet. Fingers crossed I'll get it soon, and that the battery info actually gives me some useful information when I see it draining fast next time.

1st Gen Moto360 Essentially Not Working

So, I got a new phone...Galaxy S8+. After like dozens of attempts to factory reset my 360, it finally booted correctly. Now when I try syncing things, nothing happens. In the Wear App, I don't even have the option to select a watch face. After undocking the watch (which is fully charged), it just shuts off until I redock it, at which point it boots up as it was turned off. Is this thing toast, or is there a trick to this? Never had this many issues with this before.

Anyone?

Ah ? thinking you said : After undocking the watch (which is fully charged), it just shuts off until I redock it,
so when watch is not on charger it shutdown ?

You're misunderstanding my issue. Nothing is syncing to the watch, and the Wear app gives me no option to pick a watch face.

I tried resurrecting this again, but it's still having issues. Popped it on the charger, and it acted like it was going to start up, but went into a charging screen. Eventually it'll boot back up, but when I swipe down and start swiping right to get to settings to do a factory reset, it just turns off after a couple swipes. Is this thing just dead? Battery is over 60%.

Your battery is bad. It shows good battery % numbers, but it can't provide enough current to keep the watch running when off the charger.
Replace the battery and it will fix some, if not all, of your problems.
