My S4 will randomly shutdown (even though I am not sure that it is really turned off or just locked in a black screen).
Mostly this will happen, when it is on the charger, but also had it happen (rarely) before in the pocket.
After disabling some Apps the shutdown would happen less often and lately really only had it happen when it was charging.
Sometimes I can get it to reboot, by pushing the power and or home button really long, then it will reboot to the charging screen or to the boot screen. After that it will just stay on the battery charging screen or on the Samsung Galaxy S4 boot loader screen.
To get it working again, I will have to take out the battery and then put it back in, after which it will reboot normally.
Currently this will happen about once a week.
I changed the charger and bought a new battery, but this behavior didn't change.
I am not sure if this is a hardware problem, or due to the fact that I disabled too many apps (with Titanium Backup) and restricted some more by using Xprivacy.
But I never had problems before and can't remember having changed any settings lately.
To get more info I let CatLog run in the background and the following messages are the last ones before the log stops:
BatteryService update start

What is the best way to go from here, without enabling too much stuff again, to troubleshoot the problem.
I assume you run a stock rom and are rooted. Did you remove the Knox apps? You should make sure that all the Knox apps are deleted.
Maybe this Xposed module can also fix your problems.

Sorry, yes I forgot to mention, its stock 4.2.2 and it's rooted.
I removed most Knox Apps with Titan Backup and currently only KNOX 1.0 is still there, but actually frozen.
Are there more steps to remove Knox?
The xposed module is for 4.4 so I am not sure if this will help.

Just to be clear, I know the basics about rooting and installing custom ROMs, but I do not know the fine details.
My 10.1 (purchased at launch) first started to experience a bad constant battery drain while in sleep mode when using stock ICS about 3 months ago. Shortly later, MTB wouldn't start up when connected to my PC, even after factory restoration. I rooted it and installed JB 4.1.1 with the 3.1 kernel, but the battery drain continued and I still could not get MTB to start up to transfer files via USB. I tried doing the various battery calibration and reset tricks (fully charge, shutdown for 1 hr, use tab until battery at 40-50%, shutdown for 5 hrs), but the drain continued while on standby. I decided to just deal with it and got into the habit of turning it off when not in use and using Kies Air to transfer files.
Now, the tab thinks it is constantly charging even when it is not plugged into the wall. While on, it will say "charging" on the lock screen and show the charging symbol on the battery. When turned off, it will show the battery icon constantly moving the green charge bar. For this reason, the battery continues to drain even when off.
Any solutions here? I tried factory restoring and using different ROMs (ICS and JB) but I think they used the same kernels? Do you think there is something physically wrong with the battery or the chip that controls the detection of charging and charge levels? Or perhaps the Tab thinks there is a constant USB connection? If it is something physical, any hope of repairs that will not cost close to the value of a new tab?
Any information would be appreciated
Thanks!
So I got this s5 a few days ago from my friend...moment I got it I noticed that it overheats a lot,for example 5 minutes of browsing and the cpu temp would go up to 70 degrees celsiu,also the screen got really hot.Yesterday I also noticed that the screen has a burn in,which is common for amoled,but then I thought that maybe battery is causing all my problems. Tried to charge it with original sammy 3.0 charger,it goes to 100% but never shows the green led and batt full sign.When I restart the phone batt goes to like 95-94%. So what do you people think?

How to Fix Bad Galaxy S5 Battery Life:
1. Find Apps Eating Up Your Battery
2. Disable Unnecessary Services
3. Restart the Samsung Galaxy S5
If you start noticing weird battery drain and or your device starts heating up, you should try performing a reset to see if that returns things to normal. Most of you know how to restart the Galaxy S5 but we’ll remind you anyway. Hold down the power button, confirm that you want to turn it off, and then hold the power button down to turn it back on.
4. Start Using a Black Wallpaper
There are tons of them out there. After you’ve downloaded one, go to Settings -> Wallpaper -> Home and Lock Screens -> More Images -> set your black Galaxy S5 wallpaper.
5. Start Using the Device’s Built-in Features
You’ll also want to start using the Galaxy S5’s built-in battery saving features. Power Saving Mode is a good place to start, and Ultra Power Saving mode is an even better option when you need the Galaxy S5 battery to last longer than normal.
These features allow you to block background data and turn on grayscale mode which can help to limit the amount of juice being sucked up. You can also slow down the processor, reduce screen performance, turn off the lights on the buttons, and turn off GPS to save battery life.
We also recommend getting familiar with the the brightness slider. The screen can suck up a ton of battery life so you’ll want to monitor the brightness of the screen if you’re starting to notice bad Galaxy S5 battery life.
6. Replace Your Launcher
If none of these fixes work, there are three other drastic solutions to try. The first is to replace the TouchWiz launcher on the Galaxy S5. The TouchWiz launcher has been known to hinder performance and it can be replaced. There are tons of different launches to choose from though the Nova Launcher is one of Android’s most popular choices.
7. Downgrade to Android 4.4 KitKat
If that doesn’t work, you could try downgrading to Android 4.4 KitKat. A Verizon Galaxy S5 user recently put together a step-by-step process on how to move back from Android 5.0 Lollipop and those interested can find the instructions here. This isn’t guaranteed to fix your issues but it’s worth a shot if you don’t want to wipe the device or if none of these fixes have an impact.
FIXING GREEN LED LIGHT
Go Settings -> Display -> LED indicator -> Charging has to be checked.
You can also try factory reset. This will fix all kind of bugs.
LED light is showing while charging...but only red LED,it never shows the green light even though the batt is full...this is just basic stuff that you told me...but anyway thanks.
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.
Howdy, everyone!
I have a problem with my G935F: the battery percentage stays stuck while the device is on, it gets updated on reboot but then won't change. If I connect the phone to the charger the icon in the status bar reflects that but the charge level still won't update until the next reboot.
Battery life is great and charging while the phone is off shows the correct percentage throughout, which makes me believe this is not a problem with the battery.
The phone is rooted and I'm on stock 6.0.1. I've already tried multiple full wipes and flashing several versions of the stock rom (including Nougat) but the problem persists. I've also tried clearing the cache and the dalvik cache to no avail.
Do you have any ideas about what the problem might be or what steps I may take to try and fix it? I'd like to rule out all possibilities before dishing out €50 to have the battery replaced!
Maybe you have an app that's interfering with the reported battery level. Does the battery indicator update properly when you boot the phone into safe mode?
Unfortunately, no.
No ideas?
Unfortunately the battery level is still incorrect even when the phone is booted in Safe Mode. However it is correct when the phone is charged while turned off and the battery life is normal, which makes me believe it's not a hardware problem...
Hey guys sorry to bump old thread , but found this thread and its good to not always make new threads Well, i also suffer some heating issues but recently my battery percentage stuck at 82% while i was charging with hotspot active , i dont know why it got stuck , but when i replugged the jack in usb port , it continues but after sometime stucks again at 84% , i cleared cache partition but its still the same. But if i turn off the phone and charge, it will proceed to 100% , so the only changes that i made in system are enabling developer options and installing nova launcher and xwidgets app , phone is not rooted and completely stock. Any hints guys ?
So I have been having some major issues with battery drain and not sure why. When I was stock I would see this as well on 14a and now on 15a. I am stock rooted and removed RCTD with the app.
Wakelock App shows usage from RILJ? Not sure why. It seems like turning Bluetooth off occasionally stops the drain and heat so fast but it starts back again after the fact.
I have factory reset a few times to rid this issue that keeps randomly popping up. The only other thing I am guessing it may be is Samsung Health possibly causing this but the wake lock doesn't show that.
