So I have just bought a galaxy s4...three days...it shows, at least imo, a masive battery drain, meaning that after 10 mins of normal ussage(2-3 mins reading news in an app, 2-3 mins of 9gag and 2-3 mins of fb) it dropped from 100% to 85%...also it heats up preety quick also...i did an antutu stability test an the temp was at 40C..though i think it was more thant that...coming from a badly jailbroken iphone 4 running ios 6.1.2 that ate my battery constantly I still have the impresion that it was more reliable thant this....after 4 hours of ussage i had to recharge the battery on the galaxy having droped to 20-30%...I will also present my appologies for not reading the entire thread..but are there any solutions as of yet?
[Galaxy S 4 General] s.illes79:
define 4 hours of usage... 4 hours screen on time is good if u play a game or something, 4 hours standby time is rubbish.

post some screenshots of battery usage also install a wakelock detector and post some stats.
[Galaxy S 4 General] is77gal:
Well i must admit that durring the said 4 hours i was most of the time browsing this forum trying to fiind an answer and installing various apps to fiind the temp my phone is reaching....not satisfied with the answer though..below 40(i know what i said,not sure about the app or me) but it seemed higher. As for pisc i admit i must first learn how to do prindere:))) and what apple to use...i will try your suggestion...10X

bye bye wakelocks

4% battery used over 8 hours in standby with Full stock 4.2.2 with WIFI on, 3G on, sync on, Location Service On

Deleted apps causing wakelocks:

- facebook ( drained most battery even with disabled notifications, fb rot in hell :D )

- shareprices

- all battery apps: betterbatterystats, 2x battery, batterystats widget ( look like i'm better of without them )

4% battery used over 8 hours, not bad isn't it

this also sorted out other kernel wakelocks: msm_hsic_host and NLPCollectior wakelock are now minimal

Lesson learnt: stock config is probably have good battery life until user installs battery hog applications like facebook.

MASSIVE battery drain here! Unplugged at 11pm, its now 8am and 36% just went with NO usage. Nike app was running, but i had ALL location services and GPS turned off. Wifi and data on, but i had the same problem with location turned on. Last time, google services were draining a lot. Facebook sync off.

Could also be because of weak signal in my room, but still..maybe, i will test this as well.

Then, i will instal the battery app, and post the results here, but if somebody has any idea, what is going on, then please, tell me.

EDIT: And still going. This is even after i restarted the phone

EDIT 2

Well, after restarting, turning wifi on/off, going out for a while (at work the whole time), and recharging from 37% to 88%, I have now lost 2% of battery over 3 hours, doing only a few minutes of light browsing the phone.

Worst ever battery life. 2.5 hours real racing gameplay = 98% battery gone
[Galaxy S 4 General] -sandro-:
I don't want to offend anyone but 95% of these posts are most definitely useless because no one uses it the same way. You post screen times, ok..but what have you done with it? If I play games i get one result, if I watch a video I get another (much higher).

All I can say is that what I do everyday is chat on WhatsAPP, emails, browsing and tapatalk. No games or other heavy stuff, when I'M ALWAYS ON WIFI i was able to get once 6h of screen time but the average is 5h, when I'm on 3G DATA ONLY I was able to reach 3h screen always on the same spot and with great coverage, once you move around or are in a place with medium to low signal I think I could struggle to reach 2h screen time because the battery level drops quickly even on standby.

So unless you describe what you did with times or you don't say or stay connected to the same type of network all the time these results have no meaning if not to you only. As I said being on wifi all the time or on data is biggest game changer IMHO

what should I do guys? auto brightness with litle usage of mobile netoworks and wifi! I don't think that's good
[Galaxy S 4 General] ardom:
Check the apps running in your background. Uninstall if you don't really use them. I usually get 3-4 hr screen on time with wifi and 3G. Mostly 3G since they don't allow us to use company wifi. With total of 11-12 hours run time

Only getting screen on time of 2 hours. that's it. something must be wrong with the battery or the phone. brightness auto-5. on official 4.3 stock rom. mainly used for surfing the web on chrome, or whatsapp as seen on the screenshot attached. all very basic tasks for the phone. No games whatsoever in the review period.

anyone has any ideas?
[Galaxy S 4 General] nicolas57:
Check your Wi-fi !

I had the same pb, you have to switch to plane mode, then return to normal mode
[Galaxy S 4 General] uranium:
What do you mean something is wrong with the wifi? what can I do to fix this? I restarted the phone. would that help?
[Galaxy S 4 General] nicolas57:
look at your first screenshot, wi-fi !

You have to switch in aireplane mode as soon as you reboot your phone then return in normal mode

I think that the problem come from the Baseband Modem you have installed
[Galaxy S 4 General] uranium:
I believe I managed to fix it by switching off the location settings via WiFi if WiFi is off. so that has helped. doing another test to see the battery life.

I have to mention though that this is a third party battery and that might be the cause of a lousy battery life. I'll next test the original Samsung battery for a comparison as well to see if its the phone or the battery.

[Galaxy S 4 General] uranium:
really? no sync? but what would that do? disable syncing anything at all?
[Galaxy S 4 General] OnlinePredator:
It means that apps won't be establishing a data connection every set amount of time. Chewing through data either on wifi or 3g consumes more battery.

I have to say though all this battery saving talk...seems so silly to turn everything off and run in low power mode. Weird getting this awesome powerful phone with an epic screen and great performance, then disabling or limiting everything on it. I just charge every night and leave everything on (GPS, WiFi, sync etc etc) and max screen brightness. Gotta say the screen looks epic at full brightness and enjoying my phone a lot more than when I was worried about what apps were chewing my battery up and making sure I switch everything off all the time (let a lone squinting at the screen to try and read it when outside in the sun.....)
[Galaxy S 4 General] ven4545:
Probably 20% of brightness, sometimes higher when outside, all sync, ohh and huge deal for me was to have everything on vibrate or silent, that way media and os won't activate as much, yup wifi all day but with carrier signal which is why it's one of the top 5 spots in battery stats

[Galaxy S 4 General] uranium:
I managed to improve the screen time a little from just about 2 hours to slightly over 3 hours by taking certain steps and disabling apps that I don't require anyway. this is using the third party battery that I bought.

thought it should be noted that I get vastly superior battery life using the original Samsung battery with exactly the same settings. Screen time 2 hours with remaining battery of about 75%.

I've sent my gt-i9505 to Samsung 3 times... Got a battery replacement 3 times... A firmware re flashed also.... Yet I get this stupid battery life... No background processes... No faulty apps... Tried using wakelock detectors... But painfully... With no use :(

Just goes for around 9 hours with a screen on time of 2 hours... Just crazy!

No gps... All the smart features turned off... No bluetooth, no nfc... I just don't get the point... How do you guys get such amazing battery life??

So it's been three days since I received my Hyperion 5200mah battery. Although the correct battery timings and percentage maybe shown after 4-5 cycles of charge-discharge-recharge, I'll post the screenshots of mine and will post again after the 4-5 cycles...

The charge cycle said is to be 10-12 hours however the battery is charging to a full faster than the said time. Could it be because of the difference in voltage? If I'm not wrong, US uses 110v mainly and here in KSA we have 220-240v. Could it be because of this?
[Galaxy S 4 General] NHS2008:
Here's how battery works for me.

First two shots are at 15%

and then reading flip board till it reached 1%.

I don't know why Wifi shows always on but I had it off for the night.

Sync always on. All the Smart ass features off. Reading mode on. Adapt display. Brightness manual set at 30-40.

Rough Usage was:

15 mins of music

30 mins of Web

2 odd hours of reading on Play books

30 odd mins of flip board

10 odd mins of YouTube

20 odd mins of GTA SA and Asphalt 8

Plus some random stuff...

Using Stock mj9 4.3 with root and latest Adam kernel.

Pretty happy but would like an hour or so of screen time.

That is a pretty bad result. It seems you have a good setup though. I'm on 10 hours, with 55 mins screen on time and still 69% left with 3G on all day and Gmail syncing all day. Have you tried installing Betterbatterystats or Wakelock Detector to see if a rouge app is keeping your phone awake? I recommend installing both and monitoring any wakelocks over a 24 hours period. I also have location access turned on to use mobile network only using KT kernel.

Have you tried a custom kernel? Location access off? Android Device Manager off? Wi-Fi scanning even when Wi-Fi turned off is off?
