Samsung Galaxy S 4 Review - Part 1
by Brian Klug on April 24, 2013 12:01 AM ESTCPU Performance
For our CPU analysis we're left with our usual browser based benchmarks. Again this isn't an ideal list of tests but it's the best we've got for now. Where necessary we'll show results using both stock and Chrome browsers. We did notice a single case of thermal based throttling under SunSpider 0.9.1 (the benchmark alone is ine, but running it after a bunch of others caused throttling), so we're once again presenting results in our standard test environment as well as inside of a freezer to show peak performance. Although the Galaxy S 4 managed to throttle in one of our tests, the device never felt all that warm to the touch. We could be seeing some of the same aggressively set thermal governors that we saw back with the Nexus 4. It's also worth pointing out that we're simply in an era of pushing the limits of just how fast you can go at 28nm LP in many of these smartphones. The mobile SoC vendors also need to do a better job of power management, enabling controlled bursting to these high frequency states vs. sustaining the higher frequencies until there's a serious enough thermal issue that the CPU cores have to throttle themselves significantly.
Under Kraken in particular we see a measurable improvement in performance over the 1.7GHz S600 used in the HTC One. Qualcomm still can't attain the peak performance of ARM's Cortex A15, but once again we're looking at a much lower power profile.

Not saying that. the ability of plastic to flex enables the little catches around the case to lock/unlock easily. to do that with alu you need a mechanical release which increases complexity. As a material plastic has advantages over glass/Alu and personally I don't mind it, not saying that I don't appreciate other materials just that as a functional cover it does its job well.CoryS - Friday, April 26, 2013 - link
The Droid X had a metal back plate, without a mechanical release. It also always came off in your pocket..zero2dash - Wednesday, April 24, 2013 - link
I'd rather have a plastic shell with a removable battery and a microSD slot than a metal frame with neither.But hey, whatever's most important to you...

How often have you removed/changed your smartphone battery in the past? Just curious how often people who find the feature important use it (since I don’t know anyone who does so in real life).CoryS - Friday, April 26, 2013 - link
I did it daily with my Gnex. But, never have had the need with any other phone. The peace of mind is nice though. I think I have found I no longer need to swap batteries as much because I have changed my usage model to the battery life of the device...meaning I don't use my phone as much so it doesn't die.RiotSloth - Saturday, April 27, 2013 - link
I have an S3 with 2 batteries - I don't think I have ever swapped the battery out because I have a charger in my car and at work. Love dragging those batteries around and keeping them charged though.... and of course people buy phones because of how they look or what they are - saying that isn't so is just denial. Just because tech geeks don't doesn't mean others don't. How many people do you know who have phones they barely know how to use, but bought because they had heard its 'the one to get'?Androidtech - Sunday, April 28, 2013 - link
For all of you talking about removable batteries. I have both the Galaxy S3 and the HTC EVO 4g LTE. Out of these two phones the Galaxy S3 is my primary phone while the HTC Evo tags along and gets used randomly when I think about it. This is because I use my phone constantly and I stream podcast all day long at work to a bluetooth speaker. When I run one battery down I just pop in the other one and start charging the backup with the handy dandy Sammy battery/charger combo pack. Since my job is one that I am always on the move this is a great feature for me. I build oilfield pump packages and rebuild Industrial gearboxes like those used in ships and sugar mills.The ones in the ship turn the giant propellers and the ones in the sugar mills turn giant grinders. I also do welding and fabrication. So in a job like this I am always getting tools and moving from one part of a project to the next part or the next project. I am almost always standing up. This is much different than an office job where I could just plug my phone in at my desk. Even then why would I want a wire attached to my phone. Personally I would prefer a metal phone with a mechanically removable back maybe like the HTC Amaze 4g. Also as far as the case discussion goes There is no way I would use either of my phones with out a case and screen protector especially in my work environment. I like to keep my devices in top shape so when I am ready to get a new one next year I can sell it for top dollar or hand it over to my wife so I can use her upgrade again. That way I can say hey baby here is a nice phone and it still looks brand new ! She does not care about the latest and greatest or the fact that she is a year or two behind current technology and I always have the newest thing out since I am rotating 4 upgrades if you include my stepsons phone. You see there really is no reason to argue or try to decide which phone is better just get one HTC phone and one Samsung phone and enjoy the different qualities that each brings forth. Just be the one that pays for the famliy mobile Bill and you too can use everyones upgrade and stay on top of the cutting edge handset race. Works for me !Dug - Monday, April 29, 2013 - link
I don't know anyone or have seen anyone that changes their battery. In a company of 200 tech geeks I would think that this would be the majority and probably why HTC went away from it.TedKord - Thursday, May 2, 2013 - link
I'm a very heavy user. Hours of streaming Netflix, surfing endlessly. I can carry a second battery, and just swap out when the first runs down. I don't have to worry about carrying a plug,So to answer your question, I have at times swapped out my battery every day for months on end. Now, I'm rocking a 4500mah extended battery, and I always make it through the day.
I have a buddy at work who had an iPhone 4s, and it's battery had nearly died. He was getting a couple of hours max, but was out of warranty. He'd have killed for a swappable battery. Instead, after using my SGS3 and being impressed, he went out and got a Note 2, and left Apple all together. He hasn't regretted it a bit.

Although you can change the battery in an iPhone fairly easily... or he could buy a mophie. I think everything has been said now about batteries - to some people it matters, to others it doesn't.
