Default S4 gets hot+drains battery in 4-5 hours staying AWAKE all the time

I am a frustrated user of Samsung galaxy S4 user. During the last few days, my phone is playing weird. First it started getting very hot when I put it on home wifi (which is like always connected, phone does not have to keep on searching and connecting again and again for wifi). Connecting on wifi the phone temperature (through a widget) would reach to 42 degrees C which is usually around 25 degrees C. The battery in these cases would drain within 4-5 hours. I checked it and found that the phone remains “AWAKE” unnecessarily throughout the time when I am doing nothing and phone is sitting idle with black screen. I tried taking the battery out, restarting and doing all kinds of soft check but nothing worked.

After couple of tries the only improvement I saw was that temperature was brought down a little bit and now it was around 35-37 degrees C, but the battery drain issue was still there. In the meanwhile I checked it couple of times with wifi off and mobile data on and the same battery would give me around 46 hours of .life and no heating issue.
Now the recent update is that even it has started doing the same thing over mobile data too. The system has gone very slow in response. Simple typing the text shows considerable delays. Intermittent freezing of the phone for 10-15 seconds in the middle of doing something is observed. Phone is not heating that much but it still warm. No signs of improvement in battery life what so ever. Now even if I put it on mobile data it acts the same way. 4-5 hours of full battery life maximum.
Observing the battery profile, I see that all that my phone stays AWAKE, my battery drains at very high rate and that is the time when “I” am not using my phone. Its awake on its own. When it is not awake, then battery graph becomes flat. I go in the battery and it shows me that maximum battery is used by ANDROID SYSTEM.
Can someone please tell me how to put your phone to sleep (opposite to AWAKE) when it should, so that it does not stay awake and hence give me a good battery life and I get rid of pauses and delays in responses.
My phone is attached to a carrier so it is not a jail broken version. It is still under warrenty, I called Samsung and they want me to send it to them and they will look into it. I am a bit reluctant as I think the guys I talked to, they did not bother to listen the whole issue and after just listening first few sentences they asked me to send it to them.

Please help,

I am hoping that some experienced user will answer your exact question. Personally, as and when I have had similar problems or any problems for that matter which are not solved by quick googling, I have resorted to factory reset. Majority of the time, whatever is happening is fixed.

That said, I am a new user of S4 (Google Play Edition) and it was my first overnight charge last night. When I picked up the phone in the morning, I felt it noticeably warm (not hot). With room temperature in mid 70s (F), I was kind of alerted by this new phone. I am going to watch how it goes and may be both of us are going through the same pattern.

Default How to disable the apps running in the background

So last night I kept trying to disable the apps running in the background by going to setting>app manager>Running>stop, but I still see that all those apps come back again few seconds later. How can I disable the apps which are running in the background and keep my phone "AWAKE"

I suggest get a battery monitor and learn what apps are causing your phone to stay awake. My personal fav is Battery Mix:
https://play.google.com/store/apps/details?id=jp.smapho.battery_mix

Being on a Canadian carrier, I don't know what bloatware your phone comes with. Hard to know what you can kill and what you can't. There are lists here which give some general info in that regard.

Here's one such thread:

Welcome to the Android Forums. before I try to advise you about solving your problem, I need some more info. You mentioned that your phone stays awake, meaning the screen stays on and doesn't time out. If that is the case, what is the screen timeout time set for? Under the battery stats, how long was the screen on for? You mentioned the Android system is consuming most of the battery. In the battery stats, what is the total time its running for? (To see the time in the battery stats, just press whatever your interested in seeing more details about from the listed apps and processes.)

I am glad that my post got the attention of some senior members. I am hopeful that I'll find a solution now. Awake means working in the background, not the back lit screen thing. Screen goes off within 30 seconds. I was talking about the awake function which you can see in battery status.I am posting here the screen shots of battery status when my phone is running on mobile data and wifi is turned off.

You can see that graph is quite smooth and not that steep. As all the time the phone had been on mobile data. It was not awake most of the time. Thats good and thats the reason why it gave me a better life. Later today or tomorrow I shall post the pics with wifi on and you will see the difference.

Also I noticed that when I look at the apps running in the background when in "upset condition" (on wifi) , the running apps keep coming coming in and going out of that page very frequently which shows that as soon as I put my phone on wifi, apps start running on their own.

Another observation is that when on wifi, my app store does not update the apps. I can browse the net and use the internet on wifi but for some reason my app store can't update the apps. It keeps on saying downloading the updating, installing but it keeps on doing that for hours and nothing gets updated.

Please help

Honestly, I don't see anything wrong with your battery drain. Actually, its pretty good. Tap the screen and android system to see how long they are running. As to the apps trying to update while on wifi, that might be a setting thing. (Check how apps are updated from within the Play store settings.) Also, some apps might have a setting, within them, to down load data when on wifi only. (You might want to check the settings on those apps.)

I'm not an S5 owner, or a techy, but for the last year I have been a power user of a note 2 (my first smart phone), if there's one conclusion I have come to, it is that many little quirks of these mobile phone's are in the settings,
A few months ago I found some interesting little quirks pop up on my note after the major software update, it took a while for the penny to drop but some time later I decided to go through the phone settings, which I did over and over which yielded good results.
So I'm not any help to you but that is where I would start.
I did find through looking over and over again some settings I had missed the first couple of times around.
Also if there's an app user manual or an on line one , there may be some valuable info to be had there for your problem.
Best of luck.

I use better battery stats to get more specific details. However some options require root access . But it still could help . Have you tried doing a battery pull to see if that stops a rogue app ? I sometimes will try that before a full restore. https://play.google.com/store/.../details?id...betterbatterystats.

I have go task manager on my note 2, I find that is pretty handy , I paid a few buks if a recall to get full functionality , i use it on occasion to see how much memory I'm using, it also has sort of a tune up feature, it may be worth a look.
The other some things I have learned with my note, I don't always need the screen on full full brightness, most of the time indoors I run it at about half brightness and that's plenty, also making sure things like gps are turned off, also looking at your app s and update settings is a good thing,
For example I have some factory apps/bloatware that I don't use, never will, so I make sure auto update is not turned on for those apps, as i mentioned in my earlier post I believe a lot of problems that people have with smart phones are in the settings, and it does take a while to get the hang of it, i would say keep at it, you will find the happy medium with the settings.
Goodluck.

Default Fixed

Finaly I got it fixed. Just deleted about 20 apps which I never used and will never use. Surprisingly my battery is more than a day now. This was never this good, even when it was brand new. I am happy. Its running good so far for the last few days both on mobile data and wifi and battery is perfect

Thanks a lot group
