Galaxy S5 vs Galaxy S3: the real upgrade comparison

Kris Carlon

When the Galaxy S4 was released there was a lot of criticism leveled at Samsung for dropping a flagship successor that didn't improve significantly enough on its predecessor. That may well have been the reason consumers didn't flock to stores to snap up an S4 in quite the volume of numbers Samsung had hoped for. It still sold a ton of S4s, but that experience apparently left a bad taste in the Korean super-manufacturer's mouth, a taste they vowed to remedy with the Galaxy S5 launch. And yet, the same response has been heard around the world following the unveiling of the new flagship: the Galaxy S5 is just an S4 with some more features. Check out our our Galaxy S5 vs Galaxy S3 comparison.

Whether you share that opinion is a matter for your wallet and your next smartphone choice, but the simple fact that so many Galaxy S3 owners skipped the S4 upgrade means that quite a lot of those S3 owners are in a prime position to capitalize on the S5 as a real update alternative. While the minimal improvement between the S4 and S5 has many eying the Xperia Z2 or upcoming HTC One 2 instead, if you're committed to Samsung, the Galaxy S5 is the update you would have been waiting for. So let's put the two side by side and see if how they stack up. I'm comparing the Snapdragon-based models only. Update: I've added the Exynos specs, as some readers didn't like the Snapdragon-only specifications being used.

As you can see, if you are looking at making the jump from the S3 to the S5 you're in for a real treat – the Galaxy S5 is a significant improvement on the S3 in many different ways and would be a very noticeable leap forwards in terms of hardware, performance and experience. The same can not really be said between the S3 and S4, or the S4 and S5. Sure, if your S3 is still awesome you can stick it out until the unconfirmed Galaxy F appears later this year, or you can switch teams to any of the upcoming HTC, LG or Sony devices, but the fact remains, the Galaxy S5 is probably the best smartphone out right now even if it will be surpassed in the very near future, but this is almost always the case. The real question is: do you want to sit back with your comfortable S5 and watch other Android devices push the limit more aggressively?

Are you an S3 owner considering the jump to the Galaxy S5? Are the S5's specs making you consider another OEM's flagship instead?

    I have had my S3 gi300 since June 2014. Was very impressed with it to begin with but now I find it lags quite a bit whether it be going from one app to another or turning camera on it can take what feels like forever to do so. Very annoying particularly if you're trying to take a photo and you have to tell the people in the photo to wait! I also find the battery life very poor. I have to charge my phone during the day.Why is this the case? And is the S5 going to be any better in these two areas? I am considering the IPhone 5s instead?

    @Kris Carlon, which phone do you have? Just curious?

    I have an S3 and I do love it so I won't be making the change to another company's phone. Just call me a samsung stalker, it's okay with me. I am not nor do I ever plan to be an apple user, for the record. Just too much for I'm not a fan of the very un-universal charging system they have. I think, as smart and amazing as they may be, they are too big for their little britches. Anywho, my other real question is what are your thoughts on the water-resistant feature? With a toddler who likes to grab my phone and run away with it sometimes and has come dangerously close to dropping it in watery type this a feature worth my time?

    samching does only one thing well .. hardware

    I will never get a samching (tablet, phone, microwave, tv, toaster) unless there are stable custom roms available for that device so that I can immediately remove the garbage that is touchwiz and samching software

    Is there any benefit to the S5 vs. the S3 regarding battery life?

      Tons. The S5 obviously has general battery improvements beyond the size increase and general optimizations, but the two biggest changes are the presence of Lucid Logix tech in the S5 which does an amazing job of stretching the battery out and the excellent Ultra Power Saving Mode, which can drag out even more when you really need it. The S5 has one of the three best batteries around right now.

    I have had the Samsung Galaxy 3s since it has been out on the market.It has been the best phone i have ever owned. I have never had a problem with the battery life, hardware issues or any other stuff. The only problem with the phone is sun light. If you are outside in the sun you are not able to see the screen at all unless you move to a shaded area. As far a the network connection (Verizon) or able to get clear phone calls it is completly perfect. I have dealt with the Iphone (restrictive) in which case find them to be lower quaility the Samsung devises. I don't know what the aveage user is looking for in a phone, it seem as through if you throw a 8 core processor it would be too much or people would complain that it sucks the batterey too fast.
    I think Samsung does a balancing act tring to create that satisfies all with out completly make the phone and battery sucker or too slow to use effectivily.

      You're absolutely right. I've spoken with execs (from other companies) that have told me just how little money is made by the uber-expensive flagships. It's the huge volume of mid-range stuff that brings in the real money. As a tech publication we are of course in the business of bigger, better, faster, but the average person (including us, really) simply don't need octa-core, 64-bit, 4 GB RAM pocket-sized mainframes. Candy Crush and WhatsApp are simply not that demanding!

    For me it's time for an upgrade. I really like the S5. I have seen several reviews on YouTube. TouchWiz seems to be better than ever. I have rooted my S3 to get rid of TouchWiz but on the S5 it seems to be running very smoothly indeed. Plus I like the fact that it is water and dust-proof. I dropped my S3 in a deep bucket of water and almost killed it. But me being an East-German, I solved the problem myself. I disassembled it myself and let it dry and put it back together.

    But now it's time for a change. But I will stay with Samsung for now.

      I actually like the Galaxy S5, within reason. I think there's better improvements on other devices and so on, but it's still a great phone. The point a lot of people miss is that if you are releasing the S5 and S3 owners are not impressed enough by two generations' worth of upgrades, that you must be doing something a little bit wrong. Of course, not everyone feels a burning desire to upgrade every six months, but a two year old phone putting up a winning competition in the minds of many S3 owners should a bit of a wake up call to the R&D dept.

    I still have a S2 that does everything i need perfectly well and still plays almost all games on the play store (even tegra games using chainfire 3d), I still dont plan on upgrading untill maybe next year. almost everyone i know that has an s4, htc one, z1 ect can hardly notice the lower res screen unless they are holding the phone stupidly close to their face and with custom roms it is still pretty fast. At this stage I see next to no reason to upgrade.

  • HendrikJB Mar 11, 2014 Link

    Check out the poll on Android Police where 75% indicate that they will most definitely NOT buy the S5. Only 9% say that they will stay with SamGONE

    The funniest feature of s5 is heart rate sensor.

  • Dave Jarratt Mar 8, 2014 Link

    I actually hope Samsung choke on the S3,S4,S5, issue. They are bringing models out in dribs and drabs,purely to sell,without consideration for most consumers. I would guess that these guys already know what an S10 will look like and do;their research has to be way ahead of the game.But bucks is bucks and if they trip a little out at a time,i.e. from S3 to the theoretical S10,then we just sell more produce and pretend to keep the customer satisfied. I have given up! My S3 is more clever than I am,so why should I keep on shelling out the bucks in drips and drabs,just to keep Samsung's books in the black.Samsung (and to be fair--the whole damned lot of them) are just gold-digging and we are fool enough to carry the waste away from them.Without sites like yours,the lights would go out,cos our Makers and Shakers tell us buggerall--except buy buy.So bye bye.

    The big question we really need to upgrade that often? I've had my Motorola Defy for 2 years now. It runs CM 10.2 (OS v 4.3.1) really smooth, and plays games very well.Not really looking for an upgrade.Guess what, its a single core 1 Ghz and 512MB phone. I am pretty sure the S2, despite its low resolution screen, will run any version of android perfectly for 2 more years with its 1.2Ghz dual core and 1GB ram.
    Still looking to upgrade to(from) the S3?

    The Samsung S3 had been one big pain after the other...I'll be going fOr the new HTC ONE or nexus

  • Cliff Keller Mar 6, 2014 Link

    I used to be a big Samsung fan. They have not fixed the S3 ROM update problems as yet and the S3 has terrible battery life and many other problems. I use three batteries a day and have the GPS, Bluetooth and WiFi turned off. The S5 is not much improvement over the S3. I will probably look for another phone maker when this contract is over in July.

    My i9300 is still a damn good phone. Does everything I need it to do. Do I need newer hardware? If I'm playing games, maybe, otherwise, no need for an S5. Their health apps are good if you're just starting, but I'm on Nike+ and Polar, so these additional software features mean nothing to me. If the Galaxy F is an S5 in an "iron suit", then forget it.. Long Live the S3!!!
