Hi all! I've had my note for about a month with no problems, but last night it went flat in 11 hours of no use.... The battery use screen shows that it was the OS with nothing else running!
I have this problem too, really need to know answers!
Do u leave ur wifi,packet data, gps and Bluetooth always on? This may be the problem,just use any battery saver tools and close unnecessary hardware

wifi - yes
packet data - dunno
gps - no
bluetooth - no
but i always have the same settings - why such a sudden drop in battery life?
Check if you are in 3G mode or 2G.... 2G save a lot battery
Im happy can reach 5 to 6 hours screen on

Something definitely running @ background. Try restart your phone, everything wil be ok back

Installed anything just before the drain problem?
Pretty much all the problems I've had with battery drain have been traced to an app misbehaving. The battery stats info can be a bit misleading too - so don't trust that the OS itself is draining the juice... Its more likely to be some service app that doesn't show up a itself on the stats.
I've found Widget Locker a painful battery hog, for example, but it never shows up in my battery stats. Instead the Android OS, or whatever last write to the system log (log cat) show up as using all the power. Uninstalling WL always fixes the problem so I know its that app causing the drain.
Also, is that shield in your notifications bar some sort of battery saver?
If so it may be the cause not the saviour! I've read that the latest free version of Green Power tries to connect to ad-servers constantly and drains the battery double-quick. Apparently the premium version doesn't have this issue but you have to pay for it, obviously!
the issue is undoubtedly running services..you probably added an app or three that is high maintenance.
shut down and restart your phone and then without starting or using any apps, leave it overnight to get a better benchmark for battery life.
If still low, look at the running services, you may be staggered to see what amount of crap is running in the background..

how do we find what services are running?
Mine hasn't had any new apps installed and normally loses about 7 percent overnight. The shield in the pic is lookout which I've always used without a problem. I have restarted the phone so I'll see how it goes today. Its wierd because nothing has changed in use or apps so something must have hung and run it down.
I'll post any other findings!
Thanks

just done a hard restart
turned off wifi
removed weather widget
removed live wallpaper
turned off haptic feedback

some tips for better battery life.
Hi all,
New to the forum. Sorry if somebody has already posted something similar. Tried to search but could not find any.
The reason I am here:
Yesterday night before going to the bed, my phone battery was >80% charged. In the morning I found my phone switched off. I had to restart the phone using the power button. The battery was at about 40% down when I turned it on.
I dont use the phone much through out the day, so it uses around 20% in a day(morning to night).
There is nothing unusual that I can see in the battery usage stats. Attaching screen shots for reference.
The graph shows a sudden decrease in the battery power. I am not sure if any sofware can consume so much of power in such a short time, unless there is a hardware issue or the battery readings themselves are incorrect.
This is the third time in the last 5 days that I found my phone powered off in the morning with a sudden fall in battery power.
I am using the stock android 4.2.2 with all the updates applied.
Can anybody please help me understand whats going on?
When it drops straight down it signals either a reboot or a power off. Something is causing your phone to turn off (obviously), it isn't just a battery drain issue. That said, it shouldn't drop that much if it is off.

Thanks josh, is there a way to debug whats trigerring the shutdown? What worries me is the sudden power drop? Could this be a harware issue?
There might be some safety mechanism which will shutdown the phone in case it finds the battery current is extremely high. I am just guessing.

The battery % indicator isn't completely accurate so whenever you reboot your device it tends to show as a lower value than before you rebooted it. I find that whenever I reboot my device the instant drop is then offset by a slower than normal drain as shown by the indicator. Obviously the drain is no different but this is just what the indicator is showing.
I wouldn't worry about the drop itself so much, just what has caused the reboot. I can't help you there so maybe someone else has an idea on how to figure that out, good luck!
Try flashing the stock image again; efrant's guide in my signature is the best & most educational way to go about it..
P.S. overheating will shut the phone down. Maybe some rogue app misbehaving? Long shot but could be it. Search for betterbatterystats here in xda, see if some app produces some crazy wakelocks. If not, go back to the top..

You can monitor with betterbatterystats.
And if you are rooted you can check the root features in advanced settings to see any alarm that occur.
This will help you debug the problem.

I wouldnt be worried about the battery drain.. That is usual for your situation as you hardly use your phone, the battery reading isnt always accurate and is most accurate after a reboot.
If your reallt worried. Reflash stock images fromm Google. Don't use toolkits and learn something about fastboot and your phone.

Hi,
I bought a Galaxy S4 - GT9505 and before a few months ago. After updated to Android 4.3 (official firmware) I have been facing a lot of problems, such as battery drain and the main problem is when I have wifi or mobile data turned on, and when battery is at 60-65%, for instance, my device shutsdown randmoly. And then I try to reboot but it goes to samsung logo and then reboot again and so on. My only option is to connect to the power or usb and then I can reboot. When I do this It starts charging in 60-65% so it recognizes the real battery status.
So, could you please help me with this issue?
Thank you in advance.

I also have this problem. But in my opinion - if you have custom ROM with custom kernel (read below):
#Your phone reboots (before reboot on the screen you can see 4 lines, glitching...)... - It occurs If I set CPU to maximum speed (2.3ghz). So if I use 2.16ghz speed - it occurs rarely...
#You say that your phone sometimes boots twice - I just ignore it and pull batery out/in and that's it... You don't reboot your phone so often...
# Battery drains fast? Check settings, there is "battery usage" and shows which program uses battery most.
!!! Always use "Battery saving mode" on galaxy S4 - it does....NOTHING except saves battery, and very well. I haven't noticed any performance reduction...
#Not sure, but do you have battery isues? If yes, go to recovery menu (yep, shut down first) and wipe cache ETC... I read in forums somewhere that if you want to calibrate battery, just charge it fully, than pull out the battery, WAIT about 5 minnutes and put it back... Not sure about this method, check google
How old is the s4, did you buy it brand new or secondhand? If its secondhand hand to you It sounds like your battery is coming to the end of its use able life.

Hi,
My S4 is brand-new. I bought it on August. Do you think I should replace the battery, even if it only happen after the upgrade?
Thank you.

Hello
I have a samsung s4 i9500 new phone about 4 months old. I encoutered many battery problems so i installed Arrow rom, which i fell in love with it in a sec, it had everything and the battery life was just amazing. (Thanks to all who contributed into making this amazing rom).
But something happened when i installed an app about adds and it kinda restored my phone yo factory settings, i didnt care much for the reset, but i found out that my battery life ia no longer like before. Let me give you my states before and after.
Ps: i reinstalled the rom hoping better resulta but it was the same
I sleep usually at 1pm and wake up at 10. Thats 9 hours, when my phone was fine it only drained about 10% or 12%.
But as in for today for example, i slept 7 hours and it drained 20%.
Most of the draining came from android oa at 89%.
Please note that before i go to sleep i always charge my phone to 100%
Is there something wrong? Ill do any test to solve mu problem.
Thanks all

Hi.
U should install BBS app and post "other" and "partial wakelocks" screenshots so that we can tell what's eating up yr battery life.
Cheers.
deep sleep!
Yeah BBS is definitely the way to go..also you might want to check skipjack's awesome thread for better batt life when idle (insanely )

I got better batt life with my s4 after i did some of their tips on this thread..
Sweetdreams to your phone's battery! ))
I have attached my files, btw the battery is kinda weird, one day it drained about 40% but somedays drains way less, keep in mind that when i go to sleep i turn off my wifi and use edge network, and power savor too.
Some solutions that I follow that kind of stopped severe battery drain and got the phone in deep sleep mode:
- Disable "Scanning Always Available" from Advanced settings of WiFi
- Disable GPS and 'Use Wireless Networks' from Location settings menu
- Greenify apps and a few services
- Before putting the phone down for good, clear all the recently opened apps by pressing and holding the HOME button and clearing them all. Then open up the task manager and clear RAM.
- To get the phone into deep sleep (you can monitor this using a free app called WakeLock detector, available on PlayStore), if you have the habit of switching on the screen and then switching it off whilst being in the lockscreen mode (just like you check time quickly without unlocking the device), the S4 DOES NOT go into deep sleep mode even though the screen is switched off.
To solve this, you need to unlock the screen, get to homescreen and switch off screen from there instead of directly locking/switching off the screen without unlocking the device. Yes, it's hell and I don't know why this issue persists :/
hello
my Galaxy s5 is not doeing so well with the battery. my stats are in the attechment
some people have 2 days on there phone with 5-6 hours screen on.
i only have wifi on and all the other stuff like location services and bluetoot etc, is turned off
can somebody please help me so i can use this phone like it should be
The latest update has improved battery life...
Sent from my SM-G900H using XDA Premium 4 mobile app
1 install Android Assistant, search for it on Google play
2 check what apps are using the most Cpu time
3 decide what you need and what you can uninstall (careful).
Mind you, some apps may not appear in the list and be often using cpu time anyway.
In addition, try the app 'Greenify', it can help a lot in saving cpu time and energy, if you learn how to.use it.
Also (only for rooted devices) use Autorun manager or a similar app to select apps you want to prevent from starting at boot.
Hi
I will try tht thanks.
When i look with gsam the android(os kernel) is at 82%!
i think that causes the battery drain right now but dont know how to fix it
Hello
Right now i have this when i got it of the charger. and i didnt do anything with the screen so its less that one minute of screen on time.
I think its pretty bad

I had this same issue. Mine was overheating when i used any app and sucking up battery life like crazy. Yesterday I did a factory reset, reloaded my apps, and installed the latest firmware update (NF6). So far everything seems to be back to normal. No more overheating and no extreme battery use/drain.
oh ok.
I only have the battery drain but no overheating yet
But isnt it to quick to putt it back in factory reset since i only have it for like 3 days
