[Galaxy S 4 General] dllebandroid:
I have bad battery life since the update to kitkat on sprint. Android system and android os are draining my battery fast. It is unfortunate because i used to get 4hrs 45mins -6hrs 30mins of SOT in a 16hr-30hr span on JB. I did a factory reset already and still don't know what is causing the issue.:confused:
[Galaxy S 4 General] FalconFX:
Battery drain fix !!!

Hello everyone, i thought that i need to let you know guys that i had really bad battery life on 4.3 official rom lately, and here is how i fixed it !!

First of all, a couple weeks ago, i dropped my galaxy S4 in water, and after 24 hrs it got back to life as it was before, but something weird happend after i started using it again. All my wifi profiles that were on my phone were wiped so i had to re-enter them manually, the second thing was battery drain, before i dropped it in water i used to have 4Hrs of screen time and 30% left at the end of the day, but now only 2;30hrs at max, i couldn't relate to the water at first, but yesterday i noticed that the colors of my screen were very saturated, so i checked the Display settings and i found that the display mode was Dynamic !!, i had it in Standard mode from the day i bought it, but it changed alone !!, so i remembered that it might be the water drop that reseted it as it did with the Wifi profiles, so i changed it back to Standard, and returned back to surfing the web.

I can tell you that i noticed the difference after 10 mins of browsing, as the percentage of battery slowed from dropping down Dramatically, and i was able to get 4hrs of screen on time in 21Hrs with only 85% of the charge when i changed the settings of the display.

So if you can't get a good battery life out of your S4, please check your display settings right away, And change it from Dynamic to Standard !!!

Even if you just installed the Kitikat FW please check your display mode as it might have reseted to Dynamic, and caused the Battery drain issue :)

I hope that i helped you, let me know in the comments bellow :D
[Galaxy S 4 General] Droidcore:
21 hours kitkat :) wanamlite
[Galaxy S 4 General] Pfeffernuss:
While I respect your "fix", it won't make a difference in the magnitude you described.

Changing the brightness for example will have a significantly larger effect on battery life than going from Dynamic to Standard.

But if it worked for you, great. It just isn't a battery "fix", that's all :D
[Galaxy S 4 General] FalconFX:
I understand that it is not scientific at all and it sounds dum, but i can confirm from my experience that the effect with and without the dynamic mode On is as huge as i described :D, and if you have time, you can try doing it yourself and let me know if it made a difference or it just me ;)

Well, it's your call, if i were you i would try it out, maybe, maybe it will get better, even if slitghly :D
[Galaxy S 4 General] Trickee360:
I'm on I9505G 4.4.2 and no matter what I do, I can't get more than 15hrs w/ 3-4hrs screen time. No matter what power saving tweaks I try, it stays about the same. This is with greenify, gravitybox radio power saving settings, and semi-aggressive Lux Autobrightness settings. I think Android System is overacting, but I can't pinpoint why. Does it look like that's the problem to anyone else?

EDIT: ROM is stock rooted (I get the updates OTA and root w/ adb)

EDIT 2: Including screenshot of the battery graph to show how often the phone wakes for short bursts. BetterBatteryStats doesn't give any indication what app is doing it. Turning off Google Now makes no difference either
[Galaxy S 4 General] ak11228:
something is def wrong with your phone. It stays awake too much even when you screen is off. I had that issue when i first got my gs4 replaced due to display cracked (not the glasses). they update it to 4.3 and I was having horrible battery and phone get heat up to 97F randomly.

I pretty much spent days tying random fix including greenify and lux. I dont know what happen but after a few week of random fix. My battery got better. I get 3-4 hr screen time if im on lte plus 20-25hr standby and 4-6 hr scren time if im on wifi on day.

The last thing you might try is to factory reset your phone.
[Galaxy S 4 General] A|ex:
I am not too sure how you guys are getting <16hrs of usage when mine is around 1day 1/2 of usage/ gaming etc. Try using betterbatterystats to find out what is waking your phone up or using power.

The biggest killer on mine was google services (maps, gps, etc).

Best battery life I've ever had hands down.

Using stock Orange Israel ROM unrooted (work phone) - I use my phone heavily all day - only charge at night and I make it until 11:00 PM with more than 30% battery. This after similar usage on the Galaxy S3 that I had to charge twice a day. So this was a real concern for me.

The office had a choice between the GS4 and iPhone 5S - and the S4 has far better battery life - as hard as it is for the Apple fan kids to admit. :p

My screenshot doesn’t seem to be uploading - so you'll have to take my word for it.

I currently have 45% battery life and it's 10:15 PM and my phone has been unplugged for more than 14 hours.

[Galaxy S 4 General] pshhsp:
how about this? one hour of music, 2 hours of screen, almost 5 hours of battery (on power saving!!!)... this happens everyday with kitkat, i can't get through the day (whereas with 4.3 no problems there...)
[Galaxy S 4 General] EnormoDerClown:
An app is causing your drain. Try rebooting - when not already tried. You can see your phone is constantly awake and never goe to deep sleep!

When rebooting doen´t help you need a wakelock detector app.

[Galaxy S 4 General] omricn:
Guys I'm in desperate need of help here..

My S4 is running 4.4.2, rooted, I've greenified background apps that are likely to consume battery, I've disabled (not deleted) all of the bloatware using "no bloat free", I've turned off the apps which are not displayed in "no bloat" via the applications menu in the phone settings. other than that, I have nothing I don't use, no special apps, no skype\viber\instagram etc. nothing running in the background that doesn't have to.

Since I've upgraded to 4.4.2 I've had bad battery life, when I take a look in the battery stats in the phone settings, it looks as if the phone is waking up every minute or so, even when the screen is off, I can have the screen off for 2 hours and when I take a look at the stats, the phone woke up every minute or so for about 5-10 seconds (the little line that represents awake time is thin), and from time to time it was awake for longer duration (the line is thick) and the battery dropped ~7-10%.

Measures I've taken:

-Delete cache partitions

-Factory reset

-Complete reset including sys\data etc.and re-installation of 4.4.2.

I don't have any app that I didn't use to have a month ago when I didn't have this problem, so I really don't think this is app related, also the only things that changed since this started happening are:

- Upgrade to 4.4.2

- Root (I was not rooted before)

- Greenify (wasn't using it prior to root)

- Removed bloat (nothing was disabled before this started happening)

Basically nothing changed, only upgrading to 4.4.2+Root+unbloat.

I was always using Google now, maps, location settings are always on but had no negative influence on the battery before 4.4.2.

Could this be maybe a result of a disabled\turned off app? could this be a Root issue (since I wasn't rooted before)?

Also - all of the battery apps (BBS, Wake detector, cpu spy) are giving me absolutely worthless data.

BBS is now showing 5% per hour, when the phone has been disconnected from the charger for about 2 hours, and screen on time is 10 minutes..

BBS is showing exchange - mail_service at the top of the "partial wakelock", but even if I disable the whole exchange sync, the battery will continue dropping. I've tried disabling gmail sync, Google+ sync, exchange sync, disabling location services, nothing helps.. I'm really in the last efforts here, before selling my S4 and getting a Nexus5..

Edit: Another screenshot.. phone is now at 77%...

There is very little you can do to reduce battery drain when the screen it on, other than lower the brightness.
