Actually it is very easy to get 5+ screen on time. Just turn off all the sync features. I am getting 5+ screen time continuously on every charge cycle. Battery life is very good and better than s3.

Pretty good this time, Google Services and Facebook doing that weird thing again at the end tho which drained my battery from 20-30% to 0% without me noticing (a reboot fixes them). Only EDGE used, no 3G/4G, bluetooth on all the time with phone connected to my Pebble watch. Minimum brightness for the majority but turned it up a little bit the last day. GT-I9505.
[Galaxy S 4 General] MaKTaiL:
I decided to do a battery test today. I have all options enabled and on Automatic (I mean ALL of them, Syncs, Air View, Google Now, etc).

I used the phone almost non-stop. It's the i9505 version. I played a little Into the Dead as well when I was getting bored. That's probably why it drained so much.

I think I could easily get 5h screen time if I haven't played the game. How is my battery based on the screens below?

My S4 Battery status. ....!
[Galaxy S 4 General] exxi:
I recently acquired the S4 with moderate excitement. I already had a S3 and I was very happy with it but I had the option to get an S4 after extending one of our contracts so I went for it and gave my S3 to my wife - she's very happy with it now But i am not very happy with my S4 for 2 reasons:

- Extensive heat generation (36-47C) while surfing, watching videos, natigating calling etc.

- The heat seems to originate from the top portion of the phone on the back as well as the front side around the camera. it is uncomfortable to hold it against my hear on call

- My S3 did not heat up this much or this often. I also did not have any battery charge cliffs or jumps with my S3.

- As the device heats up, the battery drains INSANELY fast. Also I've noticed a disruptive and sudden battery discharge. As I charged my device for the frist time to 100% moments later the battery level jumped from for example 95% to 82% in one second. Is this due to battery calibration issues (because the device is new and the battery has not been charged many times yet) or is this something that can be considered a hardware flaw of the battery or device? I could be watching a video at medium brightness and my battery would go down by 1% each 2 minutes.

Sometimes during use and especially when it heats up some percentages are skipped while discharging (95%, 93%, 89% without sequencing down one by one but rather as 'chunks' of battery loss. ) did you exhibit similar behavior on your phone? Are these battery 'jumps' tied to the heat development?

And now the main questions: Should I return the device and exchange it against a new one or should I wait until Rom development or a patch tackles the problem ? I've already installed a recent OTA from Samsung and hoped the problem would vanish but no luck.

Pretty please, answer my questions I am desperate here.. especially why I get these battery jumps Thanks friends!

[Galaxy S 4 General] noideaforusername:
I think you might have a faulty device/battery. This behavior is not common.
[Galaxy S 4 General] exxi:
It feels like this is a problem for all S4's out there.

Check out this video at min 3:25 http://www.youtube.com/watch?v=aUx40kXZF5s (Steep drops in battery)

I really don't want to send in my device for no reason because I will most probably get a refurb or even a device with more problems.

I just want to know if other people have experienced similar issue.

You can check with the app called BatteryGraph and see if sometimes a few percent are skipped down the graph.

It would be great if someone did this for me

i would exchange for a new one maybe its defective and software wont be able to fix?

In battery, When screen on has blue stick, isnt activate should have blue stick as well?

I played game for half an hour but activate has very skinny one blue stick..

Also stand by time has increased amazingly after I reboot.

It was losing about 10% per night, but now its losing only 2 or 3%. I'm scared to reboot if it goes back to lose 10% per night lol

Have you done anything to get that great result? Thanks
[Galaxy S 4 General] msavic6:
In Android 4.2, Google changed the way that the "Active" and "Screen" bars work. The Screen bar will be colored when your screen is on, that's the same as it was before. The "Active" bar will only glow when something is waking your phone up when the screen isn't on, so its basically showing you wake locks.

[Galaxy S 4 General] pepsimaxmjs:
Its all about the ROM

Hi,

I have a UK supplied Vodafone Galaxy S4 i9505. Initially the battery life was a disaster. Out of the box you could watch the battery meter drain down live in front of your eyes.

After almost taking the thing back (my Nexus 4 was doing a whole day no problem), I tried a few ROMs. I tried factory and Omega 3.0.

In the end I settled for factory ROM i9505 XXUAMDM. This is rooted and has Teamwin 2.5.0.0. Recovery. I have used Titanium Pro to remove some of the Samsung bloatware.

Using GSam I have gone from 6.5 hours life to 18.5 hours life. I am a heavy user, phone, email, internet. I am running Lotus Notes Traveler (heavy on battery) and use lots of data over mobile. Sorry, no image, but I am being pretty precise! Typically screen (about 20% brightness or auto +3) is using 60-65% of the battery. Wifi active 50% of time, phone radio also about the same. Usual temperature is about 24 degrees C.

This is a remarkable battery performance for me, but please listen to my point - only getting this with my provider and this ROM. Other ROMs have unbelievably different results. Key things removed:

AllShare; ChatON; EasyLauncher; Knox; SVoice, Samsung Text to Speech; SNS; TouchWiz; SEAndroid; Kies Wifi; Group play; Epson & HP Print services; Blurb; stupid fonts; Com2uSpoker; match3VS; MyFiles; Calculator; Polaris Viewer

Also, turn off the location reporting in Google maps... this eats power!

This gives a stable ROM, performance is excellent. I replaced Nova Prime with Apex Pro launcher. Apex is smoother on S4 (Nova had some stutters).

Hope this might help some of you with serious battery issues (like I started with)...

[Galaxy S 4 General] DocRambone:
That is a nasty android bug. Its the google services that try to "call home" and if it cant connect it tries forever.

Its VERY poor design by google and hopefully they fix it some day.

The bug comes with some network connections that seems to block googles preferred ports.

Anyway a fix:

Download Autorun manager: Play

I have some suspicious of what might cause this (based on my device) and it might be the sensors works all the time (mine worked 1/4 of the time and drained 1% an hour as opposed to 1/3% with them turned off) for example.

I'm not impressed. I bought a i9505 yesterday & charged it for the first time after wich i got a little more then 5 hours before i allready was at 2% battery (4 hours and a half screen time while brightness is at auto)

Everything is default 'out off the box' & No phonecalls/2g/3g/4g because i don't have a correct format of simcard yet and still i only have 5 hours off playtime ?

I must be stupid hoping for a phone with 8 hours off screentime (especially if no simcard is inserted) but my old tablet (samsung 7" type 3100) easely get's 6-8 hours off screentime & 3-5 days in standby while skype, 3G & wifi is on all the time. (but i have to admit : it has a custom rom (all in one pac-rom) & custom kernel (agni kernel) wich probably provides a better batterylife also)

Seems kind of weak so far, but only two actual charge cycles. What is that deleted_wake_locks? I have 20 minutes of screen time and dropped from 92% to 79%, something is definitely killing the battery. I have location services on enough that it knows where I am for mapping purposes, I disabled all the air/motion stuff except for the quick view and the one that keeps the screen on while it detects your eyes, my weather app doesn't update until I open it, and screen is set to auto. I don't know what else could be causing it.
