Some of you may have noticed that battery life on this phone can be both unbelievable and mediocre. I've been trying to figure out what can trigger and cause mediocre performance and I'm at a loss. The problem is, there doesn't appear to be a smoking gun. No obvious wake locks. No rogue Apps. I have Carrier IQ disabled by System Tuner. Google Now is off. What I'm running right now is pretty bare bones. And the kicker is my phone is sleeping, as can be seen in the shots below. The vast majority of the time my phone was off the charger it was in deep sleep mode.
I noticed my phone in excessive drain mode Saturday so I let it run over night and into the next day, so that BBS and GSam could pick up as much data as possible, including sitting idle overnight and very little use throughout yesterday.
Here are some shots to show the story. The graph, which is definitely steeper than when idle drain is normal, which resulted in idle drain of about 6% per hour. Also as can be seen in these shots, there is not a wakelock problem. Deep sleep shows as 12 hours 38 minutes, Awake time of 1 hour 8 minutes, and screen on time of 1 hour. So, my phone was only "awake" for 8 minutes when the screen was off out of almost 14 hours according to BBS.
I did notice and oddity here though. BBS listed the unplugged status as 13 hours 47 minutes, while the phone's battery meter listed it at 12 hours 13 minutes.
Attached are the shots I took at 19%, as well as a final battery meter shot after charging the phone to full while powered off and restarting, where it's been purring like a kitten in deep sleep.
Part of me is beginning to believe there is a bug with the battery gauge. What do you guys think is going on?
Try clearing data for google play services,google services framework and playsore than reboot and check if things changed.
And i would recommend uninstall the updates related to those apps and let them update itself again.

Done. Although I won't know if any attempts to resolve the issue have worked until the idle drain triggers again (or doesn't).
Thanks for the advice.
Well unfortunately that didn't solve the issue. The heavy deep sleep drain again triggered after a bit over one full day. I charged to full last night and let sit over night where it drained 6% per hour with no obvious culprit. Anyone else have any suggestions?
It seem that your signal is week, did you get stable signal and have you tried airplane mode, to find out how much battery drain in this mode?
Also, did you disable LG MLT? This is a massive app from LG, can consumed about 150 MB RAM.
This might sound boneheaded, but what about just resetting the phone. Maybe some system app is causing some type of memory leak and thus draining your battery. Also disable wifi when you're not using it.
I don't think it's signal related. I get an excellent signal at work and the idle drain still occurs. Also, it happens whether wifi is on or not. I have not disabled MLT, as I'm not concerned about RAM, just running processes. Rebooting the phone eliminates the issue, so something is obviously getting hung. The really odd thing is I was draining 6%/hr overnight, all while the phone was in deep sleep, yet my top battery consuming category was the screen at 35%, with just 1 hour of screen on time of 10 hours off the charger. If something was cranking in Android System that caused 40% drain overnight I would have expected Android System to be higher. It doesn't make any sense.
I may just have to factory reset.
My battery's been great until couple of days ago when I turned on GPS and Voice Notification (for speaking out names when phone call/message comes in). After I noticed the abnormal battery drain, I turned off those two options, because that's the only thing I did differently before noticing the drain. However, that didn't help... yet. I needed to do a reboot and battery's been fine again. Not sure if those two were the actual culprit, or just coincidence.
Have you changed any settings right before you noticed the drain? Just a thought.
had the same issue., wakelock detector, BBS, GSAM nothing could show what was eating the battery. i use mobile browsing a lot and almost 8/10 times this battery drain was happening with chrome , chrome beta and firefox browsers.
Only thing thats helping me is the Greenify app . Greenified the chrome and firefox and almost all the cloud apps and the battery is now much much better.
still ...IT IS AN PROBLEM to be found..
To provide a bit more info on this, attached is a pic of my reboot a couple hours ago (marked by the thin white vertical line). The change in the slope of the drainage line is drastic. Also, notice the small hump after the reboot? The line actually increased a bit, fell, then flat lined. More and more I'm beginning to suspect the battery gauge, but I just don't know.

I have the same situation after charging. Even in"deep sleep" it would chew through the battery. Now I just reboot the phone after charging and it plays nice. The gerbil on the wheel seems to take a break and rest.
To all who have excessive battery drain, did you charge your phone while it is on or off?
Some where in this forum (if not mistaken), I read that there is a bug while charging G2 when it is on. You should reboot your phone after it is fully charged otherwise you will experience excessive battery drain.
Mine always charged it while it is off and never had problem with battery life.
i got the same issue which is very annoying, have over 85% deep sleep, no wake lock, battery draining like crazy, and it happens randomly. I wonder if factory rest fixes the problem, or hardware issue
i have done a bit testing for this random drain,
with mobile signal on ==> huge drain
without mobile signal on and only phone signal ==> huge drain
airplane mode ==> no drain
so i believe it is a bug within the phone software, actually sometimes the random drain started after a phone call
I've been getting the drain too in the past few days. Last time i could fix it by factory resetting, but obviously I don't feel like doing that once per month. What I do know is that flashing another stock ROM (kdz) without factory resetting doesn't fix it. However last night I figured i'd try disabling WiFi (kept it on during the night until now) and I only drained 1% in 5 hours, down from 3% per hour. Perhaps this bug is related to WiFi.
Have you disabled LG MLT? It acts like CIQ for internal LG purposes. I have personally seen it cause mass wakelock in unexplained situations. If I leave everything on overnight under 95% battery, I will get around a 3% drain in about 7 hours. Pretty normal. The first 5% on these batteries seem magical. At 100%, with everything on, I wake to 100%.
Yup, frozen in TiBu. Will be factory resetting however when I get home as GSAM grabbed my attention. Never were system things so high up the list when i had no drain.

I been struggling with this since I got the phone (almost a month now). I've done all the usual:
Removing bloat
Disabled CIQ
Disabled Google Now, Location, GPS
and I have the same apps as my Nexus 5
Just last night I realized that this battery drain only happens after taking it off the charger. This got me to add the word "charging" in my search and I found this thread.
Is this hardware related, or would a custom ROM resolve this? I have the AT&T version.
Ok and which stock rom does not do that?

Probably this is a software issue. Never heard this problem on latest firmware or custom ROM.

Guys could you write which stock rom does this wakelocks for you so we could eliminate corrupt firmwares?
For example I experience these wakelocks on latest F international version.
Recently, my N4 decided to no longer enter deep sleep.
I have no idea what the cause is.
I'm on Mahdi ROM 2.5 - http://forum.xda-developers.com/nexus-4/orig-development/rom-mahdi-rom-2-4-t2581007
My kernel is Hell's Core B46 T4 - http://forum.xda-developers.com/nexus-4/general/qa-kernel-hells-corejb-kitkat-b43-t2495373
I have never had any problems with the Kernel, so I don't think it's the kernels problem.
As well as, I have switched to several different kernels, and nothing's changing this behavior.
About 1 week after using Mahdi(about yesterday/the day before), this problem began occuring.
I tried a full wipe, and just installing the ROM no GApps or anything. It still would not enter deep sleep.
I tried flashing PAC Rom 4/18 Nightly, and no success there either.
I have been suggested that I am having WakeLocks.
So I downloaded WakeLock Detector, and Better Battery Stats.
According to them, most of the wakelocks are coming from " Android System" & "Google Services".
I have tried using the WakeLock Blocker installed in Mahdi to stop the WakeLocks by these two, it seems like it's working a little bit.
As now, I am getting a 1 minute or 2 of deep sleep per hour, as before I wouldn't even get a minute in a whole 24 hours(I haven't touched the phone once within these periods) But, the rest of the time it just sit's on the lowest CPU Frequency(81 Mhz).
I am pretty much stumped on what to do now, so I am coming here to ask you smart fellows of XDA. :good:
I'm in quite a rush as school starts back up tomorrow, and I need my phone.
Any suggestions are helpful :3
Edit: It might be helpful to know, right before I began having WakeLock Problems, my battery was all psycho. It would "charge fully" in 5 minutes. Die in 15 minutes. Then I can reboot it and it would have 60%.
I ended up rebooting it everytime it died, to COMPLETELY drain the battery. Then when it would no longer boot, I charged it fully & that was fixed. Now it's just these dumb WakeLocks.
Did you try stock ROM? If you still get wake locks in stock ROM then the one or more of your apps is rogue.
For finding the best results, turn off always scanning in WiFi, turn off location.

Hi Guys,
I upgraded my Exynos Note 3 to Kitkat about 1 month ago, and everything was fine till about 3 days ago when I started experiencing some really bad battery drain. For the last three nights, my phone does not go into deep sleep mode at all. I first noticed this because I usually switch off data and wifi at night. Normally, I'd loose 3% battery overnight, which is good. About two nights ago, I woke up in the morning and I had lost 40% battery (90% down to 50%) overnight! When I checked out the battery stats, "gpsd" had used 80% of the battery.
Since we no longer have batterystats access in Kitkat, I installed the desktop version of WakeLock Detector, enabled USB debugging mode and connected my phone. Phone had basically been awake 97% of the time. Under kernel wakelocks, "l2_hsic" was shown as being the culprit. Now I have searched through various forums online (including xda) to try and find a solution to this. Suggestions vary from home screen replacements (nova launcher) to mobile tracking software (cerberus/findmymobile etc) to generally anything that uses location services. Some even suggest clearing application caches, disabling location services etc. I have tried every suggestion with no change. I uninstalled all mobile tracking apps, turned off location reporting, location history, and eventually location services. I've removed all battery stats apps. I uninstalled all my apps and re-installed them one by one, all with no change. Finally, I backed up my phone and did a factory reset. That seemed to work at first, but after about 3 minutes, "gpsd" was back again, and my phone would not go into deep sleep.
I've done 3 factory resets, and with no google account or samsung account configured, I still get "gpsd" rearing it's ugly head, preventing the phone from going to deep sleep and draining my battery. I'm at wits end.
Anyone know how to fix this? Would appreciate any help!
Anyone!?
OK, so I decided to take out my SIM card, just to see it'd make a difference, and what do you know! "gpsd" no longer takes up CPU time! So this is somehow related to my SIM card? Funny though, coz I'd even tried putting the phone in Airplane mode, but "gpsd" was still taking up CPU time. Does that give anyone an idea as to how this can be fixed?
bump
I'm having exact same issue with my exynos Galaxy S5, shame Samsung.
For the record, my issue fixed itself. Didn't do anything at all. It just went away and never recurred. I'm on the Russian lollipop ROM now, loving it!
Almost a year after the issue fixed "itself"... I have the same problem with my SM-N900 running offical lollipop, Im afraid I cannot wait a year to let the issue fixes itself... and cannot find a solution either.
Anyone that have managed to solve this?
THANKS IN ADVANCE!!
Hi there, for the last week or so, with no new apps being downloaded prior to issue, I have noticed a significant battery drain by Android OS (39%) and inside it showed incredible Keep awake time of 16h 50m (though the phone screen is off). For reference, the screen time (25% battery usage) so far is 1h 31m. I have installed and given root access to GSam Battery Monitor (its root companion is activated too). The program indicates that Kernal (Android OS) is taking up my space but I was hoping instead it would be able to give the direct app that is eating up my battery. I have tried restarting it twice and after letting the battery run off completely and fully charging it before turning it back on.... no dice.
S4 - SGH-i337M (jfltecan/jflte)... verified root... Android 4.4.2
SlimROM-4.4.2.build.4-OFFICIAL-3650
Build number: slim_jfltecan-userdebug 4.4.2 KVT49L 3650 test-keys
Kernal: 3.4.82-KT-SGS4-gb0a91ad
Recovery is via TWRP
I know there may be suggestions to turn off GPS, WiFi, etc, etc... but I'd rather not do that due to the fact the phone life was absolutely fine w/ them on... I'd like to fix the root of the problem instead of working around it. I haven't made any changes to phone settings for a month. Reformat is a last resort but want to exhaust options prior to.
Any help appreciated, thanks.
It seems that the only way to have figured it out is by disabling individual apps and see if there is any improvement in battery life and drop in Android OS wake time and battery use.... After checking the 4th app of possibility, it seems like KiK was the culprit. Just going to remove the app as I haven't used it much. Maybe an update for the app occurred causing this to happen. One work around for those who want to keep the app that's causing the issue and minimize the battery drain, you could just go to the app's system settings and do a Force Stop and the program will be off and then turn the app back on whenever you need it and then turn it off again via Force Stop. It's a app issue, not anything you can really do about it except downgrade or uninstall the app.

I had a massive battery drain issue due to 7000000.ssusb wakelocks. My phone is rooted and i updated "disable_host_mode" file to "Y". Since then the battery drain decreased by a half. But still there is 9-10% battery drain in the period of 6-7 hours of idle period. BBS, showed there is around 98% Awake (Screen Off), I am quite not sure what is causing this, but I am certain that 7000000.ssusb is not causing this. I have attached the following screenshots of BBS.
I just wonder what might be the reason for this. I have -
1. Turned off wifi, data and location.
2. Put phone in Airplane mode
Can anybody point me to right direction? Thanks
Friend of mine has the very same issue. I suspect a HW defect, but he's lazy to go to a service center, so I can't confirm (yet)..
We tried rooting/unrooting, several reflashes of stock ROM, factory resets with/without apps restore etc., result is always the same - pretty much no deep sleep.

Yup it is a hardware issue. I fixed it by changing charging port
You could try install a custom kernel and use the boeffla wakelock blocker to block 700000.ssusb. I guess you are on Oreo?
