[Q] Battery Drain after unplugging - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Hey there,
Recently after patching to 4.4.2 on Telus, I have found that my S4 has been draining quicker than usual. I tend to only get 10 hrs charge on it now, but the odd thing is that occasionally when I unplug it, it will go from 100% to 77-75%. I'm not quite sure what the cause is, but I'm guessing it is battery wear due to heavy usage? I am just curious if this is the case before I consider getting a new battery for my phone.
Any help that you guys can provide would be greatly appreciated.

There are countless threads on battery. Start with the obvious, open battery settings and see what's draining your battery. Restart/pull the battery.
Are you rooted? Get wakelock detector from play store. Figure out if you have any apps that cause wakelocks and then fix it. Or if you're getting poor signal in your area, that can lead to battery drain.
Try apps like deep sleep battery saver if you have wake locks. Or use tasker to control your radio if you get bad signal in certain areas.

Mostly says screen and kernal, been using Lux to try and keep the screen brightness down, but it has been draining faster than usual. Have tried restarting/pulling the battery but to no avail.
Not rooted, and have been keeping an eye on signal, but the drain occurred even when at home with full bars.

[Q] How have you improved your battery life?

I'm looking for best practices and successes rather than commiseration.
I'm running JuiceDefender on aggressive and still not getting more than a day of use (3g+BT off, wifi 2hrs, screen time 3hrs).
If you've managed to get some kind of improvement, please share what you did and how much of a difference it made.
I've installed betterbatterystats and saw that trillian causes a hell of a lot of wakelocks, so I've disabled that. My battery usage graph is much smoother and less steep but I can't put any numbers on it.

Thanks for this. I found out that it was the Smarter Alarm app, which was activating hundreds of times an hour and preventing my phone from going into deep sleep (this app wasn't a problem on my Desire HD, just on the Note).
Here is a shot of BetterBatteryStats showing 4hrs of non-deep sleep followed by 8hrs of deep sleep:

And here is the battery graph. You can see in the top left how even when the screen and services were off, the battery was still falling at an unusual rate:

An aside: JuiceDefender didn't prevent this from happening, but did heat up the phone noticably. I've since turned it off.

How long have you had it? Remember that it takes a week or two before the battery reaches its full capacity.

I've had it 11 days. My battery life has been all over the map, anywhere from 8hrs to 55hrs, depending on usage and wakelock activity. My one-day limit started about four days ago.

from my understanding of how juice defender works, i believe it closes off non-essential background apps to save battery?
the problem with this is that if the app is designed to remain running at all times, then youre only going to cause problems when running juice defender. juice defender will close the app, the app will reopen itself, juice defender will close the app, the app will reopen itself, etc. its a reboot loop for the app, which will end up draining more battery than simply leaving the background process running.
i dont recommend using any app killers. they all do the same thing and just end up chewing through your battery more. if you want to really disable an app, use titanium background to freeze it.

GSam Battery Monitor Screen Usage?

Every night, my battery is drained by 7-8% even though, GPS, WiFi, all radios are off and the phone is in airplane mode (done automatically via LLama scripts). I installed GSam Battery Monitor to try to figure out what was going on and it indicated that even though the screen was dark, it was draining the battery (and was the primary culprit). Is this accurate or is it a bug? Anyone else seeing something like this on their Nexus 4?
Mine shows 78% usage in dark.. I think that just means how much of battery total it was used while the phone screen was off. I'm taking a completely random guess here though.

So you reset the app right before going to bed and checked it first thing in the morning and in the 7 hours you slept, the main battery drain came from the screen?
I use the same app and I never noticed anything wrong. Still, battery readings are not always accurate... sometimes when I recharge my phone, it stays 100%for a few hours, then it drops 7-10% in a matter of an hour...and that's completely normal I say you shouldn't worry about it too much as long as you get satisfying usage times..

I'm not happy w/battery life and trying to track down what the culprit is. If all major services are off at night, 7-8% battery drain doesn't seem normal to me. Granted this is apples and oranges, but my iPad Gen 3 in the same configuration remains at 100% overnight.
If doing nothing drains nearly 10% over 6-7 hours, no surprise I've got issues during the day.
I've noticed the same thing, one time I didnt turn the screen on on my phone, then I went to screen and it showed 0% discharge while screen on, and 7% discharge while off. I'm running the latest version of Viper, I'm also confused and I wonder if theres some issue where maybe power is being sent to the screen even though it's not on.

After my 7 hours sleep.. Every morning my phone uses 2% battery drainage at MAX. i.e.: Wifi Edge Sync etc ALL OFF. And I am getting 4+ screen time on my phone with moderate usage. Pretty happy with the battery life so far.

Your phone probably isn't going into sleep. The Nexus 4 seems to be prone to insomnia caused by apps that don't cause a problem on other devices.
To check this download CPU Spy from the play store. Run it, reset timers to zero, and with the phone on battery (i.e. not on charge) let it rest for 30 minutes or so, then check the figures.
You should see Deep Sleep as > 90%, if not, or it is listed as an unused state, your phone isn't sleeping.
To fix this you either work forward or backwards!
Work forward:
Factory reset, install CPU Spy, run the test and see your phone is now deep sleeping.
Start installing applications one by one and after each install, run the app, then run the CPU Spy test again.
Eventually you will find the app causing the problem, all you can do is avoid that app. Note you may have more than one app causing a problem so keep checking after each install.
Work backwards:
Start by un-installing an app at a time restarting your phone in between then running a CPU Spy test. Start with any live wallpapers (even if not set to be used) you have installed, then any weather widgets. Note just un-installing is not enough, you must restart after each one.
Eventually your phone will start deep sleeping again so finding the problem app.
Hope that helps.
Regards
Phil
I tried your advice, and my phone is going into deep sleep around 90% of the time, so I don't think that it's a rogue app. I keep my phone on the dimmest setting at all times, and I only get 2.5 hours of screen on time. I have an anker battery.

Excessive Deep Sleep Battery Drain

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?

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.

Terrible battery life? What gives?

Hey guys...
Just here to say that I unplugged this phone at around 5 in the morning, and around 5 hours later its already down to 74%.
What did I do? Only about 10 minutes of mobile hotspot, a 2 minute phone call, and three text messages. The rest just idling...
1/4th of my battery life for just that?
What the heck?
Everything is disabled and the screen brightness is low... Whats the matter with this phone?
Looks like something is keeping your device awake.
Can you please add some screenshots of your battery graph?
In addition, you can try to boot into safe mode. If your problem is gone in safe mode, a third party app is interfering.
If you're rooted, try installing Wakelock detector or BBS (Better Battery Stats) and check out what is waking up your device.
If you use Gas Buddy, it was known to be causing massive bluetooth wakelocks. Either uninstall it or update it to the latest version.
Set your wifi to 2.4 ghz only. On 6.0 and 6.0.1, the 5 ghz band has been causing abnormal battery drain and keeping phones from entering doze mode. Here's the issue being reported: https://code.google.com/p/android/issues/detail?id=197460
If neither of these make a big improvement, you'll have to use your battery stats (and if rooted, use Better Battery Stats or Wakelock Detector) to specifically see what's keeping the phone awake. In either of these apps, filter the view by "Alarms" or "wakeup triggers" and you'll see what the heavy hitters are.
Be sure to go into Location>Settings and turn off wifi and bluetooth scanning.
Hi.the maps app isvuding WiFi and gps even though both are disabled and I'm not using it... Any ideas?

Inconsistent battery drain overnight

I've recently bought the LG G6 and while many things works very nicely to me and overall it feels like a solid device I still have problems regarding battery drain overnight. Besides a relatively high drain I also noticed it to be very inconsistent draining from 3-4% to 10%-16 in periods of 8-10 hours under about the very same conditions. I've tried to track down the causes using multiple methods so I have a lot of bugreports going thru Google's Battery Historian tool and dumpfiles from Better Battery Stats app. I can post them if it helps but so far they didn't helped much to understand the reasons for the drain and the inconsistency as well. I though it was coming from a weak WiFi signal or poor mobile signal but it's not related. My settings are: WiFi always on, Sync on, AOD off, data on, Do Not Disturb on overnight, VoLTE is always off, Location turned on (high accuracy + iZat on but wifi and BT verification off) etc. Suggestions are welcome.
Do people not leave phone on charge overnight anymore?

I used to but I don't think it's the best practice. Probably will have an impact on battery lifespan and since we have quick charge is also unnecessary I guess. Also, losing less battery while stand by provides more SOT.

It will 'cut off' once fully charged. Doesn't cause any real issues. Unless you keep the phone for 4-5 years.

Yeah but I'd still want to improve stand by drain to have a better performance during the day.
I can confirm an issue with very high overnight drain. I turn off all radios and typically use the app switcher to close all running apps. Despite this, on a couple of occasions I woke and found that battery had lost about 25% overnight. Looking at the battery drain history it was clear that the phone had entered a very low power doze state, stayed there for a few hours and then often around 3AM would kick into some kind of high power usage state wherein the battery tanked. I don't know what the cause is, but it's not something I like to see. I often use phones on backpacking trips where there's no ability to charge and managing charge is important. With reliable doze, there's no need to turn the phone off, but with this behaviour, it would be critical.

That's really worse than what I'm reporting. My device still goes into full doze after a while on light doze. My drain is significant but never over 16%. I'd suggest you to run Better Battery Stats and look for wakelocks.
