Samsung Galaxy S4 Review
Samsung Galaxy S4 Review
The Galaxy S4 delivers passable call quality - nothing spectacular. The earpiece is loud enough, but the quality of the sound isn't among the best. Things are a bit better on the other end of the line, though there's some room for improvement as well.

The loudspeaker is powerful and manages to retain a decent sounding most of the time without starting to crackle too much.


Samsung hasn't announced any official information regarding the battery life of the Galaxy S4. Is this because it's embarrassed? Not likely! The phone is equipped with a beefy 2600mAh battery, so it should definitely provide enough juice for a full day of use. Judging by our observations, though, you can even get two days out of the Galaxy S4 if you are more of a moderate user.

We measure battery life by running a custom web-script, designed to replicate the power consumption of typical real-life usage. All devices that go through the test have their displays set at 200-nit brightness.

hours Higher is better
Samsung Galaxy S4
4h 59 min (Poor)
Samsung Galaxy S III
4h 8 min (Poor)
5h 45 min (Average)
Sony Xperia Z
4h 48 min (Poor)


Samsung didn't exactly catch us by surprise with the Galaxy S4. Pretty much all the hardware improvements like the faster processor, better camera, and 5” 1080p screen were expected. Samsung simply had to have those in the Galaxy S4 if it wanted its product to be relevant in 2013. However, it's the flawless implementation of all the features that makes the Galaxy S4 the superb smartphone that it is. Design-wise, the latest Samsung flagship is nothing special. It looks OK and is comfortable to hold. We're more than happy to see that Samsung has managed to make the smartphone even smaller than the GS III, which is a remarkable achievement, considering the bigger screen.

The top-notch performance and general lack of issues continue to be among the Galaxy S's strongest sides. If you're the kind of geek who's always running benchmarks on their phone, trying to squeeze every possible bit of performance out of it, then chances are you'll fall in love with the Galaxy S4, which is one of the fastest, if not the fastest Android phone around.

When it comes to appearance, the Galaxy S4 may not be particularly impressive, but it's extremely slim, light and easy to handle. This, along with the myriad of custom features make the Samsung Galaxy S4 one truly brilliant Android smartphone – a likable life companion.

Software version of the reviewed unit: Android 4.2.2, Build: JDQ39.I9505XXUAMC6_CSB


  • Large screen, compact phone
  • Super-customizable
  • Polished user interface


  • Mediocre call quality

Sorry. Either buying the HTC One or Xperia Z.

can you tell me why are the htc one and the xperia z better than the GS4 ? other than the design... unless, all what you want is the design ???

Can you tell me why the S4 is better than Xperia Z and the HTC One? For me- I do not care about what type of CPU. Does not affect real world performance. I do not like screens that displays inaccurate colours nor do I care about viewing angles. It's more a usability question. I do not like cheap flimsy Samsung plastic. I prefer premium materials. Dislikes oncoming. :)

"Can you tell me why the S4 is better than Xperia Z and the HTC One?" The answers are found in your own comment, it's all the things you're pretending not to care about. =3

cpu and screen are hardware, all phones now are similar in hardware... software is the thing... and the GS4 features blows both the one and the xperia z !


Posts: 1256; Member since: Jun 20, 2012

Depends one's point of view; The S4 is the one with the most software enhancements but to me most of them are gimmicky and I could imagine myself disabling in real life most of them. And if on top of that I get annoyed everytime I switch on the screen to see what 'life is...' according to Samsung in horrible faux hand written font, I'd go for the modern UI of the One or the neutral aesthetics of the Z.

no no no, smart stay smart scroll and smart pause are only the real gimmicks but theyr opening for some revolutionary thiings in the future regading being smarter with eye tracking tech..


Posts: 157; Member since: Feb 23, 2013

just like the gs3, most of those features are pointless. I know I would end up turning most of them of right out of the box, and never be using others. Bah my phone against a friend phone when I will not see them for a few hours, our just text/email them? Eye tracking meet ADHD... Yeah, it all goes off right away. So for me, outside viewing and aluminum body, or inside only with plastic body.

"Features" - 90% of buyers won't use those gimmicy "features"..whats the sense and logic?


Posts: 351; Member since: Jun 12, 2012

because S4 did not use iPhone round corner patent design. and xperia Z is upgly device


Posts: 4851; Member since: Apr 13, 2012

Candy bar edge2edge with no curve phones look more stylish sexy and slick then iPhone ugly looks! Look at Oppo5....! So you like Plasama TV with round curves and not with sharp edges! Phones that have curves look ugly!

Say something that makes sense, Please I'm begging you


Posts: 125; Member since: Jul 26, 2012

if you favor the XZ, apparently you care about one of the worst displays ever, an overhyped but crappy camera and of course the wrongly designed loudspeaker, that you block with your own hand


Posts: 145; Member since: Aug 09, 2012

i own an Xperia Z , people who have seen it call it better than all the phones out der ! Display is very good & camera is great ! persnal experience!


Posts: 765; Member since: Jan 21, 2013

oh users withn talk.sonymobile.com say otherwise :D bugs left & ryt :D speaker, call quality, battery, stmina mode, screen, signal, camera, laggy homescreen, death etc


Posts: 678; Member since: Jul 23, 2012

I am going out on a limp and say you have never seen the phone personally. You are just going off what others have said. Tell me I am wrong. Unlikely, though.


Posts: 29; Member since: Mar 14, 2013

LOL my sides ahahhaha since when was cheap recycled soda can aluminum premium? LOLLLLL


Posts: 765; Member since: Jan 21, 2013

"its more a usability question"?? yet u can only mention abt the plastic? is it related to usability? by the way when we talk abt usability, Galaxy s4 was called by some experts to hit LIFESTYLE, thats usability.. it hits Health, display adaptation for every uses, Group PLay for the benefit of several group interactions, Feature-packed camera for fun and simple photography uses, MULTITASKING, AIR GESTURES have their uses esp when your eating something and that hover hover drop down is really cool and useful, etc im tired coz i have lots to say anyway HTCone and Galaxy s4 are my favor8s get that Xperia Z and fix everything abt it so the users of that f**king phone will not be sad..


Posts: 22; Member since: Mar 15, 2013

Better camera on S4, better multitasking on S4(Read Multi-Window), screen can be tuned according to your preference and then it is far superior to z's screen even in terms of contrast, better battery backup for sure(Read bigger battery), smaller and lighter chassis, Sony on the other hand is waterproof and looks really good.Apart from this there is nothing that the S4 can't do better. Just my 2 cents.


Posts: 298; Member since: Oct 21, 2011

I say it again, you must be among the minority of people who use their smartphones without a protective aftermarket case just for other people to admire the dented or scratched aluminum/glass body.


Posts: 765; Member since: Jan 21, 2013

the final hardware unit has better call quality.. gsmarena has the final hardware unit :) so it isnt one of the cons now..

Gs4 is pentile? OMG is it true Ray?

wendygarett unregistered

Oh well, HTC SLCD 3 with 468ppi win once again :p


Posts: 125; Member since: Jul 26, 2012

don´t expect to see any pixel with a resolution of 1920 x 1080 ;) so, yeah it is pentile, but it doesn´t matter

dragonite99 unregistered

pentile with extra subpixel.. its as good as RGB

let them enjoy their dead-water-resistant-paperweight (XperiaZ) and HTC One with its bad battery and wait-forever-update. soon we'll enjoy seeing them complaining that the updates took forever (as usual with htc...) and those bad batteries (and if something wrong happened, they'll have to exchange the whole phone, and HTC cust. service aren't famous for their services...) and that physical build that called for scratch, dents, chamfered edges probs (like what happened to those iCons). soon they'll understand what those iConUsers feel when they drop their phones. and in few months, we can eat our popcorn while waving our hands on our S4 reading their agony and be thankful we didn't make those mistakes...

HAHAHA!!! that was very entertainingm because a farely new report shows that HTC is the fastest company, when it comes to updating their phones... Well, except from Apple and Google... :D hey, and you forgot to mention the Samsung Galaxy S 4 (cheap plastic, that doesn't feel like a premium device at all. And the misleading "Octa-core" that actually just 4+4... And the useless S-features that they have added...) HTC One FTW!!!!!!!


Posts: 305; Member since: Sep 24, 2012

lol, tell that to one x/+ users... ask them who get the latest android update first, GS3/Note2 users or those one x/+ users... and i won't start lecturing you about the diff. between Polycarbonate and 'cheap plastic' , you'll only see what you wanna see... btw, enjoy your so called 'premium' build, but don't come crying because of the dent, scratches, or discoloration of the plastic between the metals (i already read this problem on a german forum since the HTC already released there). i'll give it 3 months, and i'll enjoy reading those complaining of HTC One, it'll certainly brighten my day... :D

And I suppose you prefer vinyl seats to leather in your car...

I'd really like to see this "farely new report". Again the old "cheap plastic" argument. Plastic(polycarbonate) is more suitable for phone than aluminium, One X, L920 and even my GNOTE II are clear examples! Aluminium doesn't absorb shocks well and is also prone to bending, scratches and dents. Not to forget signal and NFC interference. "And the misleading "Octa-core" that actually just 4+4" You, sir, is an ignorant. "Heterogeneous Multi-Processing (HMP) This is the other actual implemented function mode of a big.LITTLE CPU. In this case, all 8 cores can be used simultaneously by the system. This is a vastly more complex working mechanism, and its implementation is also an order of magnitude more sophisticated. It requires the kernel scheduler to actually be aware of the differentiation of between the A7 and A15 cores. Currently, the Linux kernel is not capable of doing this and treats all CPUs as equals. This is a problem since we do not want to use the A15 cores when a task can simply me processed on an A7 core with a much lower power cost. The Linaro working-group already finished the first implementation of the HMP design as a series of patches to be applied against the Linux 3.8 kernel. What they did is to make the scheduler smart enough to be able to track the load of single process entities, and with that information to schedule the threads smartly on either the A7 cores or the A15 cores. This achieves much lower latency in terms of switching workloads, or better said, switching the environments (CPUs) to the respective work-loads, and exposes the full processing capabilities of the silicon as all cores can be used at once. You can follow the advancements of this in the publications of the Linaro Connect summits that happen every few months. The code was only published in the middle of February this year for the first working implementation equivalent in power consumption to the IKS." http://forum.xda-developers.com/showthread.php?t=2191850
