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.
I am using 9500 with kitkat unrooted and having some problems with random screen wake ups. It happens more often while charging and also not charging. Stay awake while charging option is disabled but still the same. How can I solve this cause it is pretty annoying.

Download WakeLock Detector from PlayStore and leave it for a while to gain data of what causes your wake ups. After a couple of hours you can check Screen Wakelock in the application and see what's going on.

try reset this phone
I have a weird issue. When my battery is well charged, I usually don't see this happen either.
My phone will start to get HOT. Most notably is upper middle right of the screen. This typically happens <40% battery, and will start to drain % per minute. If I reboot the phone, it will slow back down and cool off.
What's the best way to try to capture what is using 100% of the CPU to do that? I notice it most with Reddit News Pro, but even if I close it all the way it will not cool off and reduce the massive drain until I reboot.
Thoughts. The phone is clean, unrooted, latest update. I did a data wipe before taking the OTA because of battery drain issues.
I'm having some issues with my phone being awake when it is charging. I've checked the most obvious causes such as daydream, and the keep awake setting, but neither were active.
I'm not sure what actually keeps it awake as battery stats end up being erased at 100%. I have Wakelock Detector installed but that doesn't give me any conclusive evidence either since again, the stats are gone once the phone is fully charged. This is mostly an inconvenience as after disconnecting the charger, the battery use is about normal and I can control the wakelocks through Greenify, Amplify and the Privacy Guard's keep awake function.
Has anyone else experienced/solved this issue before and what did you do?
My current setup is:
Android 6.0.1
Resurrection Remix ROM
Nevermore Kernel
I have noticed that most ROMs above 4.4 seem to have an adverse effect on battery life on my S4 and my Galaxy Tab 2. 6.0 seems to be giving me the same standby time of 4.4 however on my tab, so I was hoping that it'd do the same for my S4 as I want to move away from using the Davlik runtime.
Always awake on charging is normal habit, you don't need to worry such thing.

Not for Samsung it's not .....at least not on the 4 Samsung devices I own (the AMOLED screens on them would get horrendous burn in if the screen remained on for long periods of time).
There is an option in
Settings>>developer options
that will prevent the screen from sleeping while the charger is plugged in, but the default setting for this option is disabled. Just double check to see if it has been enabled......
It wasn't normal in 4.4 nor 5.1, so either this was changed in 6.0 or my kernel is forcing this behavior, I may try switching kernels. As I mentioned previously, the dev options don't have anything enabled that would cause it to keep awake.
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?
