Galaxy S4 Battery Drain

I love my Galaxy S4, except for a battery drain issue.  Last night, I went to bed with about 80% battery remaining.  6 hours later, it was down to 32%.  That's unacceptable, as the phone wasn't really doing anything while I was asleep.

 

I have all of the "cool" features - GPS, Bluetooth, multi-window, NFC, Air View, etc. - turned off.  The only things on were WiFi, Mobile Data, Blocking Mode, Sync (Google account only) and Power Saving.

 

What in the world is causing my phone to lose 50% of the battery life overnight, with the screen off?

Hello there!

Sorry to hear about your battery usage.

One thing that could be the cause is the applications using background data. Try turning background data off and see if that makes any difference in battery life. Smiley Happy

Another thing it could be might be the brightness of the screen. The brighter it is, the more power it can consume. Try lowering it down to something low bit yet comfy for your eyes and see if the battery life improves.

Screen brightness is irrelevant.  This happens overnight, when I'm not using the phone, so the screen is not on.

By "background data", do you mean the "Mobile data" toggle?

Re: Galaxy S4 Battery Drain

No, when your phone's screen is off (or asleep) or actively using other apps, those apps will continue to run in the background. You can turn this feature off by going to Settings > Connections > Data Usage > Tap the menu key > Tap the Restrict Background data box.

The lower brightness option was just another way for you to save battery life, I know it doesn't apply to your phone being asleep. Smiley Tongue

Re: Galaxy S4 Battery Drain

Thanks, turning off Background Data did the trick.  It only dropped 6% overnight.

 

Now, is there an easier way to turn it on and off?  I don't see a toggle on the notification page.

Re: Galaxy S4 Battery Drain

I'm afraid I'm not aware of any ways to have like some sort of shortcut button to turn it off and on faster. Smiley Sad Perhaps there is an app in the Google Play Store that might help?

Re: Galaxy S4 Battery Drain

I must have spoken too soon.  Turning off background data worked for a week or two.  It's still off, and my phone went from 82% to 40% overnight.

 

Any other ideas?

Re: Galaxy S4 Battery Drain

My phone did the same exact thing, I did all these little tweeks like setting the theme to black, disabling push notiifcations and it still didn't do much... I ended up caving in and purchasing an extended battery. it lasts like 2 days now.

Re: Galaxy S4 Battery Drain

My battery was getting excellent life, until the 4.2.2 OTA update a few weeks ago. I posted a lenghty description of the issue in a separate post, but have gotten no responses. 

 

Same settings, same use, everything. Not sure if that is what is affecting yours, but I'm certain the last update has done something that is absolutely destroying my battery life. I couldn't believe how good it was before the update, now it is garbage.

I use Juice Defender.  There is a free version available from Google Play, but I use the Ultimate.  Under customize, you can turn off connectivity automatically.  You just set what hours you don't want it to connect.  It also tells you how much it has extended your battery life.  It says that it has extended mine 2.16 X over the last 48 hours.

 

Hope this helps!

That's quite a bit to say the least.. If I could double my battery life I would absolutely buy that app but honestly I'm a bit suspect to those kinds of numbers..  May I ask how many hours you get between charges and importantly how many hours does it say your screen was on during that period??  Also what do you keep your brightness at? Auto/20%/30%/50% ect.. 

I use GSam Battery Monitor to gauge whats eating battery life and the constants are Screen and App Usage/Android Systems..

Re: Galaxy S4 Battery Drain

I must be a fortunate GS4 owner. After the 4.3 update I am experiencing great battery life. I would drain the battery, shut the phone off and let it charge off overnight. I too have the cool features turned off and have disabled a TON of added stuff I do not use. Have you disabled a lot of the pre-installed apps??

There is always a big variation in battery life reports after a major  One big factor, is the radio software is usually updated, and everyone is going to have a different result depending on reception at their specific location.  And there may be incompatibilities with existing installed apps, or runaway processes (as you mentioned).

 

Many users will see an improvement in battery life after an update (as is the intent).  But most of those folks won't go on the internet to announce that things have gotten better.  Folks usually only post when they have a problem.

Re: Galaxy S4 Battery Drain

I've been an S4 Active user for some time now.  After "tuning" a few applications, battery life was quite good.  I do have exchange sync running 7x24 for corporate email.  Typically, I would unplug around 6p with 100% battery, maybe a couple of calls at night, but in the morning, would have 85% battery remaining after the alarm woke me up.  No issue there, until the latest firmware update. 3.4.0*2244695 applied about 3 days ago, my wake up battery dropped to 30%.  Attempted tuning apps, stopping things like Pandora (check running apps under settings) even though I haven't used Pandora in several days.  Also found ATT Navigator running, though I haven't used that in over a week.  Still attempting to tune this new build, as it seems the firmware update has caused my battery drain.  I'll post again after diddling with this for a few more days and report back.  Dave.

Re: Galaxy S4 Battery Drain

Hi there,

I'm experiencing the same thing with my Motorola Moto X.  A sudden unknown change occurred causing my battery to drain more than 3x faster than before.  The phone is one year old, and I'm a 'light user.'  Data is off, wifi is off, GPS is off, and phone has been rebooted.

 

About the same time (last week) I swithced my phone from an AT&T contract to a 'GoPhone' account....

 

Also, The same problem occured with my wife's Apple iphone 4s at the very same time?  Unbelievable!
