[Q] Need help, battery going down fast since firmware update

So i run 2.3.3 unrooted and updated to the latest firmware.
Problem is my battery goes down so fast now. 08:00 to 18:00 and it is dead. I havnt even used it much.
Normally i can just about squeeze 2 days out of it, now it is only lasting 10 hours.
If i click tools, settings, battery use, the processes display very fast, then disapear so i can not even see what is draining it.
Can anyone recomend a battery app so i can see what is using all the juice?

Use battery life calibration to reset the battery cache first.. Also see what is eating your battery after the reset

Thanks for the suggestion, but.....
1) I am not rooted as stated in my original post (so cant use battery calibration)
2) I cant see what is eating the battery as the processes disapear when i try to look, as i also stated.....
lol
Any other ideas?

Could be that your RAM is getting chewed. Buy juice defender ultimate and memory booster lite? See what's running around in the system and do something about it, root or ignore
Reason your phones dieing fast? Maybe you DLed alot of apps and they run in background, using battery.

Sorry I don't have any suggestions to your problem but there's definitely a bug or two in the new fw?
This is how my battery usage looks like. First fpse took up three rows of space but then it all of a sudden took five rows?

Havnt downloaded anything since i updated. Apart from the firmware update, everything is exaclty the same.
I think i have found the answer anyway.
There is a new feature in the firmware update that tells you when you lose signal. I presume that it then searches for a new signal and thus wasting the battery in a way that it didnt do before.
I work in a concrete building where the signal is constantly on and off and i believe that the phone is constantly scanning for a signal, probably a new feature of the firmware update.
I am going to swith the phone to GMS only tomorrow and see if it makes a difference. (gsm is a stronger signal where i live).
Im quite sure that is the reason.

Yes, this is the exact problem i have too.
Definately a bug.

Also take into consideration that if you have xLoud switched on this is also a sure way that your battery life will drain if you have a lot of audio playing.

There's nothing at all new about this. Every single cell phone released does this.

Yes i know.
But the way the Xperia Play does this has changed since the Firmware update.
I know it has changed because now there is a message that is displayed as a notification. If the notification process is constantly cycling, which it now does since the update, and not before, this may be eating up more battery power than necessary.
Since i have not changed anything on my phone, the quick death of the battery is most probable something to do with the firmware update. I believe this change to be the most likely candidate since it is the only thing that is constantly cycling on and off.
Either that or the SE data widget is eating up the battery since that is the only thing i have added to the homescreen.
Both are possible i guess.

Your device searching for a signal is exactly what is killing it. I know on any of my verizon phones I have owned when I am in an area that has little or no signal my battery will die in just a few hours. Not sure what the device is like over seas, but any time I have a crappy signal my battery will deplete very very fast, but it usually shows up in battery manage as cell standby.

Ok,how do permanetently SHUT DOWN the Phones Signal Searching? It also drains my battery too >_>

Settings, Wireless and Networks, Mobile Networks, Network Mode ----> GSM only.
This will not eliminate the problem, but it will prevent the phone searching for the superior WCDMA signal. The downside is that you can only get G and E data connections. But......this doesn't matter because if you are in a weak signal area you have no hope of getting an H connection anyway.
GSM is generally a stronger signal in my area. Probably yours too (and thus reduces signal search cycling even further because you are going to have a signal for more of the time).
I will test this tomorrow and let you know how it goes. I am sure the Firmware update has caused the phone to cycle more frequently when seaching for a signal and this is why the battery now drains faster.
Thanks to the poster above who confirmed this drains the battery too.

What you could do is do what I do... I use Tasker and have a profile that turns on airplane mode if it sees that the connection has dropped to 0, such as when I'm in the underground parts of my work building. Then every 9 minutes, it will turn off airplane mode, check for signal again for a minute or two and if there's still no signal, back to airplane mode and repeat.
There are also a few apps you can use such as NoBars that can help you do the same thing easily.

The same problem after Update to newest Version. The Network Standby is the Energy-eater in my Batterystatussettings.

Is there a solution to fix this?
Im currently losing 10% battery every hour and not even using the phone!

Anyone has any suggestions?
I currently consider my phone broke since the battery goes so dam fast.
I have not used my phone at all and am now down to 35% after 4.5 hours usage.
This, at the moment, is completely unnaceptable. Will make an offical post on the Sony forums when i get home.
Firmware update has definately broke the battery usage when you are constnatly traversing in areas with little to no signal.

Use Nobar, airplane mode....

I guess it will happen to all phones with the new firmwarw and constantly in areas with little or no signal.
I am guessing the signal search frequency has been altered for more search attempts per minute or whatever.
Going to try nobars. Thanks for the suggestions all.

"Android OS" consuming battery [POTENTIAL SOLUTION]

EDIT
I was able to solve my battery issue by formatting my SD card. Something on there was causing the battery to drain 2-3 times more quickly than normal. After formatting, I went from 6-8 hour battery life to around 20 hours with significant usage (Google, Exchange, IMAP, Facebook all on push, 3G+Bluetooth+GPS on, 4G and wifi as needed for extra speed).
Important to note, I am not entirely convinced that the Android OS and battery drain are related since I still have Android OS near if not at the top of my battery consumption screen, but the improved actual longevity is very significant. I recommend anyone having their battery run out format their SD card (and possibly USB storage) and see if that helps (obviously back up any important data first!). Good luck!
ORIGINAL POST
I'm getting pretty bad battery life, and it looks like "Android OS" is consuming most of it. I've rebooted (as suggested in other threads), checked OS Monitor for high-CPU usage processes, but nothing stands out. This is un-rooted, stock OS with no third party launchers installed.
I have a feeling if this issue was fixed, I'd be getting great battery life. This happening to anyone else?
Screenshots show the device at 38% after 6.5 hours off the charger.

That's an awful lot of awake time with no screen on time. Do you have things updating in the background frequently? I.e. social hub, Facebook, news widgets?
And not to be too obvious, but is your 4g antenna turned on?

No, I don't. I have fewer widgets and fewer accounts (haven't set up my work Exchange yet) than I previously had on my EVO, which got great battery life.
I've been on Android over a year and am quite familiar with how it works... I'm just unfamiliar with Samsung specifically and unrooted devices and was hoping someone might have a similar experience.

I have the same thing. Significantly more awake time then screen on time, and Android OS eating the battery. Also stock.

Same here too

I had this exact issue and no longer do. Here is what I did and posted in another thread:
OK I hope someone finds this useful and/or can verify. I was one of those people getting awful battery life, meaning lucky to last 8 hours from 100% to 0%. The "Android OS" process would take hours of CPU time. Now it will take up maybe 30 min over the course of the day. Here is the only thing I did between the time it went from bad to good. I changed the wifi sleep policy. It is by default (for me at least) set to never. I changed it to "when the screen turns off" and left it there for about an hour. Then went in and changed it back to never. From the point of doing this my battery life has been great.
I know it sounds strange but it seems to have worked for me so I thought I would share.

I made the change, hopefully it will help, although I'm reluctant since I haven't had wifi on all day and my battery has been dropping like a rock. Here's hoping... will report back if it helps.

I rarely use wifi as well but this setting seemed to affect the phone in general, if your using wifi or not. I might just be crazy though. Either way I no longer have the issue so

does the google voice widget pull data in the background or is it a push thing?

I'm seeing high usage (60+%) by AndroidOS also (stock, unrooted, not using WiFi, not using 4G), although battery life has not been bad that I have noticed.
Watchdog Lite indicates that this is primarily due to two processes:
events/0
suspend

Then press the menu button and then advanced.
Should then be the first option "Wi-Fi sleep policy".

I'm trying to get into the 'INFO' section to view wake locks for battery usage clues. I've tried *#INFO*1111# (as mentioned here) and the old *#*#INFO*#*# to no avail. Anyone been able to get to the diagnostic screen from the dialer?

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.

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.

Terrible battery life (H815, 6.0 Marshmellow)

Hi all,
I've had my LG G4 since September, and it's been a good phone. However, more so recently, the battery life has been terrible. When Doze decides to work on my phone the battery life is average, but it rarely seems to work. I use over 60% battery in 5 or 6 hours, and that's with most of the time the phone screen being off.
For example, tonight I went to see the new Star Wars film. Using that as a guide, my phone screen was off for about ~3 hours during that time. However, see attached, the battery is just being drained. There aren't any particular apps that I see using 90% battery or whatever - in fact, using a battery app, it looks like phone radio is using an incredible amount.
i.imgur.com/MCQ6Yz0.png
i.imgur.com/ziZEoEz.png
i.imgur.com/a8J9ufZ.png
Any tips for increasing the battery life? I don't see myself as an over user, but I often come out of an 8 hour work shift with just 20% left, and that's with mild web browsing every now and then, and maybe 20 minutes of YouTube video.
I'm thinking about doing a full restore on weekend after backing up my texts, or even ordering a new battery, but I don't feel this should be necessary.
My screen brightness is always 30% or lower. I don't know if this would have damaged the battery, but I use an Aukey quick charger.

Thanks for replying.
I've been using it for 16 days now.
I updated though LG Bridge, and software info says V20a-EUR-XX
I've not done a factory reset, no. Will that help? All my photos, music and contacts are on Google's servers so I would just need to back up SMS and a list of apps.

I've not done a factory reset, no. Will that help? All my photos, music and contacts are on Google's servers so I would just need to back up SMS and a list of apps.

Thanks. It looks like my SMS are already saved to my SD card, so hopefully they will work straight away.
I really hope a reset fixes it, as I heard such great things about the LG G4 battery (with people posting it can last 24 hours or more!), and this is very disappointing. I'm off this weekend, so I will do it then.
If anybody else has any fixes as well, I would love to hear them if this doesn't work! The phone is great so far... aside from this.

and please give marshmallow few days chance after updating to V20B then tell us how the battery goes

you have a rogue app or something, there is nothing wrong with Marshmallow 20B (or 20A for that matter) and battery life. I get insane battery life on this phone, often 22 - 30 hours of fairly heavy use.
Now granted, my phone is rooted, bootloader unlocked, running stock 20B and I have installed a couple of apps to optimize it such as AdAway, LBE security, and KinScreen, but still, you have a misbehaving app most likely that needs to be kicked off your phone!

Is there a way of finding which app? Nothing stands out. I've just taken another screenshot (disabling uploads Google Photos didn't fix it)-should screen off be using this much battery?

A reset is definitly in order tomorrow

sure, start with turning on Developer mode by hitting Build Number in rapid succession a bunch of times in Settings ---> About Phone ---->Software Info
then look in the new Developers Options section of Settings and look at Running Services & processes - you can also download an app for this such as Elixir 2
another good diagnostic tool is heat - heat and battery life are proportional, if your phone runs cool, it will get long battery life, if you pick it up and it is warm around the power/volume buttons, then something is amiss - you have a runaway app or process
download a tool like CPU Temp from the Play store and see what the CPU temp is when the phone is idle or you are doing something light like reading an article - it should be in the 78 - 89° F. range (25 - 32° C.) If the phone is not in this temp range, then something is amiss! - Also keep in mind that the main battery drain on the phone in normal operation is the display - keep auto-brightness on, and keep the display off when it is not needed! - also turn off stuff you are not using, such as Bluetooth, NFC, etc.

I did a factory reset as suggested above, and I think it fixed it. I didn't restore my LG backup as I figured that that'd restore the problem, so went through and downloaded apps again. I then left it on overnight.
After 6 hours it was still at 100% on Wifi, which is great! I then used the phone for ~2 hours (apparently pretty heavily) which actually dropped it to 58% - whoops. I then stopped using it again but this time without wifi, and it didn't keep at the same % - it seemed to drop 10% in about 2 hours. The only things I'd changed since then was install Skype (which I might delete if that's the issue), and had it on mobile data.

Could mobile data REALLY make that much of a difference? I think I'll leave it unplugged again tonight and not on wifi, and see what it does. This is an issue though if it is mobile, as I'm often not connected to a network.

Seems like mobile radio active bug, I have the same problem. While mobile data is active, my battery drains with the screen off. I have this issue since v20a and no - factory reset doesnt help at all...

[HELP] Something is demolishing my battery life...

Background:
So last night I went to bed and left my phone on my dresser with 30% battery. The phone normally drains a few % overnight. WiFi on, Location on (high accuracy), Mobile Data On, etc. I wake up this morning to find that my phone is completely dead. I thought it was pretty strange so I connected the phone to the charger for an hour or so and charged to about 96%. I disconnected my N5X from the charger and put it on my computer desk and sat down to play The Division for a little while. After about an hour, I noticed that my phone was still very warm and that my battery had sank down to 88%... I've never had this problem before, even on my current ROM and kernel setup, which I've been running for about a week now.
Problem: Insane battery drain. CPU is Awake 100% of the time, even when the screen is off. No Deep Sleep and No Doze.

I did notice, however, that the phone reported WiFi being on for a large portion of the day where I actually had turned the WiFi off. The gym I go to every day has horrible WiFi and I prefer to use LTE. I usually forget to turn WiFi back on after leaving to go back home and shower. So there's at least a 2-3 hour segment there where WiFi was absolutely not enabled, and yet the battery graph shows that it was....
Culprit:
This mother****er right here. com.google.android.gms. Specifically two alarms: ALARM_WAKEUP_LOCATOR and ALARM_WAKEUP_ACTIVITY_DETECTION. I'm not so sure about the latter, but the Alarm_wakeup_locator is actually waking the phone up at least twice a minute, which is insane. It's massacring my battery life as well.
Solution?
I've never had a battery drain problem like this before. In fact, I haven't had a drain problem like this in at least a year or two. I have no idea what to do to fix this. I've Googled this issue and there doesn't really seem to be a straight answer.
I think it has something to do with Google Now or Google Play Services, perhaps a location setting, but I've tried disabling Location for 2 hours now and it has not fixed this issue. I have considered perhaps disabling a service but I can't identify which service exactly is causing the issue.

Update! - March 22nd, 2016
After a second clean wipe and a switch to Pico Gapps, the problem was resolved. This gave me a barebones operating system in which the CPU was sleeping just fine when the screen was off. No wild wakelocks or alarms to report. One by one I reinstalled my favorite apps, avoiding almost anything by Google -- No drain / keep awake issue reoccurred. My phone is now back to normal with only one thing missing. Google Now. The Google app and Google Now Launcher are both NOT on my device and my phone is achieving some seriously sick battery life and SOT. I am confident that if anyone else is facing these issues that the culprit is Google Now and the Google Search app. Those experiencing this issue should try removing these apps if possible or clean wipe and install with a very minimal Gapps package, just as I did.

I get similar Google alarms too, but it shouldn't cause any drastic drain.

I recently had a massive battery drain but couldn't work out the cause. Was going down 30%+ overnight and nothing had really changed on the system (few new apps which I removed).
The only thing showing any high battery drain was Google play services but even that was only at 4-5% (104 ish mah in the battery stats from memory) which didn't tally with the massive drain I was showing.
Ended up having to do a full reset to sort it out and all fine now.
This was pre the March update and fixes, I did flash the fixes while I had the issue and nothing improved.

Yes but does your phone enter deep sleep? The only reason why I'm even looking at the alarms is because something is keeping this phone awake constantly.

Yes mine does go to sleep. Attaching some of my battery (mediocre) screenshots.
I would suggest turning off wifi and bluetooth scanning in location settings. I found it kept my wifi always active (even if wifi was turned off) when GPS was set to high accuracy. Sometime even if you change from high accuracy to battery saving, the wifi continued running til the phone is rebooted (at least in my case). Bad network will also cause drain, but none of these should keep the CPU firing always. Have you checked the CPU states? Is Google Service keeping you mobile radio active? How about Android OS?

Mobile signal is excellent. Full bars of LTE at work (which is where I am now). The top battery users (besides the screen) are Android System and Google Play Services. Attached are some screenshots of the keep awake times.. Something very strange is happening here. Bluetooth and WiFi scanning are both off I. Location settings.

Just factory wipes for the second time but went with a Pico Gapps package and the drain is gone. The cpu sleeps now whwn the screen is off. I haven't logged into Google yet, so I'm not sure of the cause yet.

i got the exact same problem with you.
Phone was idle overnight, WiFi on, Location set on High.
Forgot to install BBS so i cannot see what's causing it but i think it is the same thing that causes your battery to die.

Factory resetting and reinstalling my ROM with the smallest gapps package possible (Pico Gapps) fixed the issue for me. I'm starting to think it was Google Now. Shame, I really liked Google Now too, but I've signed in and installed some of my favorite apps already and there's no drain and the CPU is sleeping like a baby with the screen off.

is Pico Gapps refers to Open Gapps Pico Package? or something else?
ps. i don't use Google Now..

update :
clean flashed Latest pure nexus, using latest Open Gapps Pico Package.
*fingers crossed* hope that the problem is gone..

Yep. That's exactly what I did. Just keep an eye on the battery graph and reset the stats. I put the phone down, walked away and then came back 5 minutes later. I checked the graph and the phone went to sleep after a minute or two so I knew it was fixed. Just remember to let the ROM settle for a little while before doing this. After flashing a ROM lots of stuff needs to settle in the background.

Okay, done the exact same steps *fingers crossed*
By any chance, do you use any battery saving apps such as Amplify or Greenify?

Nice, the screenshots look promising.
Also, no, I prefer not to use apps like that and let the Operating System do its thing. I did almost consider using one of those if I couldn't figure out how to fix this problem but you can get into trouble pretty fast with those apps if you disable/slowdown/restrict/greenify the wrong thing.

yeah Right, almost installed Xposed only to use Amplify to reduce the Play Service wakelock.
will fully charge this device tonight, and leave it on idle till morning.

I do have Amplify installed to tame play services, but now I'm being tempted to do a clean flash (maybe this is all that is required? Not everyone using the same GApps package seems to be reporting such issues) and try a different GApps packages. Currently on PN GApps. Lets see how long the thought of wiping the data and reinstalling all the apps continue to put me off.

Made the mistake of firing up Google Opinion Rewards today and it asked me if I wanted to use my Location History. I declined and it somehow started destroying my battery life anyways. CPU is being held awake again. Can Google design a single ****ing app correctly?

Are you sure it doesn't have anything to do with any custom software you're using? I'm on a stock device (no root) and have no such issues, I've got just about every Google app installed and use Google now regularly.

I actually wiped the phone and reinstalled apps one by one until the issue came back and it stemmed from ElementalX's Kernel Management app somehow. I haven't contacted Flar2 about it yet because I'm not sure if it's from a setting that I touched or just the app itself.

What is EXKM causing? I thought previously Google Services was the problem.
How did you narrow it down to that app? I have it too, maybe i can test.

I installed the apps I like one by one and recorded them on a list on my computer. After each app install I wiped the battery graph and let it sit with the screen off for a minute or two and checked to see if the CPU was being held awake. I installed like 15 apps before I got to Google Keyboard and EXKM. I installed both at the same time and repeated the procedure. When I looked at my phone, it was being held awake so I knew the culprit was either Google Keyboard or EXKM. I uninstalled Google Keyboard and did a reboot. Phone was still being held awake. I uninstalled EXKM and did a reboot, phone went into deep sleep. I reinstalled Google Keyboard, CPU still wasn't being held awake. I installed EXKM again after a few minutes and the awake issue came back. I uninstalled EXKM and proceeded to install more apps and the phone functions completely normally. I have no idea how EXKM can hold the phone awake like that but I'm guessing its a setting in there that is broken? I installed Kernel Adiutor and applied the same settings and tweaks that I normally would with EXKM and there was still no CPU awake issue so it's gotta be that app.
