If you did 5.0 update on your phone, then the battery drains very quickly. if you're not then you simply do factory data reset
Battery consumption depends on the applications you have installed on the phone and working in the background even if you do not use the phone. such as; facebook, instagram, messenger,snapchat,Netflix,etc, so if you delete these apps and use them through the browser , thus saving up to 40% of the battery (day)life , the display put on minimum brightness and wi - fi, bluetooth,3G use it when you need.
li -ion batteries work better when you are not used to the end 0%,but most to 25 % and then put the battery to charge75-90% , ( why?)
lithium-ion batteries have a rated lifetime of somewhere between 500 and 1,500 charge cycles.
so if it reach 100% or less then 25% then it lose 1 cycle.(the user runs it down all the way to zero before recharging) can degrade to 70 percent of its original capacity in 300-500 cycles
With a DoD of 25 percent, where the user plugs it in as soon as it gets to 75 percent remain, that same battery could be charged up to 2,500 times before it starts to seriously degrade.
Charge a little bit whenever you can.
Lithium-ion batteries don't respond well to being charged all the way up and then run all the way down. They take much better to little bits of charge here and there.What's far more dangerous to a battery's well-being is heat. Lithium-ion batteries despise heat.
suggests that calibration Â– fully discharging then recharging your phone's battery Â– once every three months helps it maintain its charge capacity.
Still using the phone and recently received an update that as big as 360MB something,I kinda forgot what's the description but anyway it kinda fix my phone from being overheat faster(Too much app running in the backgrpund and excessive mobile gaming).Battery still drain quite fast whenever I turn on the music player and streaming Youtube video or gaming(Can't expect an old SoC built on 28nm doing well on 2600Mah battery),my S4 starts to lag even if I just wanna load Whatsapp but that should be done once I do maintenance checkup on my phone.The phone perform admireably to me but if anyone focus on a better battery life,S4 might not the right choice anyway.

To verify, please borrow someone a sd card & put into the sd card slot at your phone.
If can read sd card, confirm your sd card was corrupt.

The Samsung Galaxy S4 is the best phone the world has ever seen, I love this phone because I can play flappy bird all day long without having to charge it, the display was so clear, I was able to beat my previous high score of 2, and I was able to get to level 3.
I also love the S4 because you can install Crossy Road (best game ever) and run it at
I've using my S4 since the day it came out and I've had no major issues so far. No heating, no nothing. Only thing that bothered me was the low amount of internal storage that keeps filling up relatively easily, even though I have a 32GB SD in there.
Can anyone help me in using s4 but something happenes i can'seem to use the ussd code of my phone it keep running but no response.i have a network can anyone help me.
im use my samsung s4 since 2013 till now and its a awesome phone. . just two problem heating and battery
Been using it since June 2013, had three/four battery change and overall still performs well. Samsung really nailed it on this one. Overall I'm very happy with it. Hope it goes on for years to come.
I've been with my phone-- the Samsung Galaxy S4-- for only a few months. My mom gave it to me, and when I first used it, I immediatley LOVED it. The only problem was; the easy overheating and battery drainage of the phone. Also, I've encountered a BIG problem just a couple of days ago, and that was the irritating 'Blank SD Card' notification-- along with the problem that currently, my phone is not able to read the memory card in this device. I don't have a PC, and I tried to find ways to solve this problem without means of using a comouter-- since I think will turn out bad because of the countless amount of viruses spreading through out computer and other gadgets... All-in-all, I love my phone. But someone-- ANYONE, please find a way in order for my phone to finally read my memory card because I have a LOT of files stored in there.
