iFixit tears into the Samsung Galaxy S4

55
It's simple to crack open the Samsung Galaxy S4 and peer inside.

While we've been starting to test the camera capabilities of the brand new Samsung Galaxy S4 review unit we just got our hands on (don't miss our super shootout which puts the S4 up against the HTC One, iPhone 5 and Nokia Lumia 920), the folks at iFixit.com have been tearing theirs apart.

The iFixit crew cracked open the S4 to see what its inner workings tell us about the latest flagship phone from Samsung, and how easily it may be repaired. The S4 came through iFixit's teardown with flying colors, receiving an 8 out of 10 repairability score for its replaceable battery and straightforward disassembly.

The removable battery is a boon to customers and the environment.
The rear-facing camera boasts 13 megapixels.
The 2-megapixel front-facing camera is utilized by the S4's new Dual Shot mode that lets users insert a smaller-sized image or video into the primary image.

Amongst iFixit's findings: 

  • As expected, the device is quite similar to the previous model, the Galaxy S3. 
  • You can trick the S4's Smart Pause feature. This new function detects if you've taken your face away from the screen during video playback, and if so, pauses the action for you. The iFixit team found a photo of your face will also do the trick.
  • A removable battery ups the S4's repairability factor.
  • Samsung has opted for a rear-facing camera boasting 13 megapixels. It also sports the now-standard LED flash, a back-illuminated sensor, and the ability to record full 1080p HD video at 30 fps.
  • The daughterboard is home to a full-featured micro USB port. With MHL and USB OTG support, users can use this port for HDMI output and USB peripherals in addition to charging and transferring data.
  • The touchscreen controller, a Synaptics S5000B, is hiding behind the screen. This chip is responsible for the S4's super-sensitive touchscreen, which even works with gloves.

You can check out the full teardown on iFixit's website. We'll share our full review of the Samsung Galaxy S4 on Connect soon, until then, see our first hands-on review of the device.

Refreshing.

If this was Mac Rumours, we'd have 400 posts from 400 people explaining how good the iPhone is because it doesn't have the option to replace the battery, and how crap the Samsung is because it does!!!

Personally I love both the removable battery and wireless charging; just this (IMO) BIG convenience is enough to make me chose one phone over another ... unless of course you're an iSheep LOL ... where yet again, Apple not offering wirelesses charging is a benefit over other phones that do.

You know its true!!!!

The removable batteries are generally preferrable but generally speaking, I would be satisfied knowing that a battery *can* be replaced at a dealership or a service center. It's not such a big deal if it *can* be replaced at all. But if it can't, then it's a big no-no.

Removable batteries are cheaper to replace and easier to find. What if you don't live next to the apple store? How much do you enjoy waiting in line for hours at a service centre? It IS A BIG DEAL.

Couldn't agree more! A fixed built-in battery to me is a deal-breaker. If I cannot replace the battery myself I don't take the phone, period!

It's not a big deal when you don't replace them for 2-3 years. Are you saying that in 2-3 years you have not once been near an Apple store? And lets get real here - how many phones have you used for more than three years anyway?

The only time a replaceable battery is useful is someplace like a plane where you are out of power for a while. But even then an external battery pack takes up no more space than a spare battery.

A li-ion battery is highly unlikely to last anywhere near three years, even two years old retaining full performance is unlikely and in practice I find on many batteries (Apple included) 12-18 months is about as much as you can expect before performance drops. Hence the manufacturers only warranty the battery for 12 months or even 6 months, bearing in mind most phones are now on a two year contract that means the battery is likely to need replaced at least once.

With a removable battery you can pre-empt a failure with a spare backup battery so when it does bite the dust, it's no inconvenience. External battery packs are much larger than a spare battery and far less convenient as they have to remain attached to the device for over an hour, a spare battery can be swapped over in around 60 seconds and then the phone is back to normal with no wires needing to hang off it.

Fully agree. I could use my Samsung Galaxy Note (1.5 year old) until 5 days without recharging. I don't know if the recent update to Android 4.2 is the reason for a higher power consumption but it's now difficult to last much more than 3 days with one charge.

It would really be a PITA for me to go to an Apple store (there is absolutely none close to where I live) and it's sooooo easy to order a battery on the net (19 EUR + freight, not a big deal) and replace it myself.

There's no way I would buy an iPhone for many reasons, but that one is really a decisive one.

A user replaceable battery is much better than a built-in one as it's easy to replace. With built in batteries you have to bring it to the store to be replaced and hopefully they have the battery on hand otherwise you have to wait for one.

What is this talk of built in batteries are better than ones you can replace.......I bet the people in favour would say different if for instance the Nikon D600 had a built in battery.

I'm an iPhone user and it would be great of I could put another battery in the phone when needed.

Remember the Nokia 6310? Why can't we have smart phones with batteries like that...........

Still got my 6310i, and the battery still holds charge. However, the screen resolution was 1.5" 96x65 mono. The S4 5" 1920x1080 colour screen and maybe a thousand times the processing power uses vastly more power!

I think Motorola have been producing thicker smartphones with particularly high capacity batteries at the cost of thickness but the 6310 was obviously a very low power device in comparison to modern smartphones.

I don't know if all their stores do this- but my local Best Buy has bins inside the store for customers to drop off batteries for recycling.
They take all kinds of batteries too.
Since I go to BB often, I have found this to be a really handy way to recycle old batteries. Too bad all stores don't do this.

so, if it is an HTC One battery, you have to dump the whole phone in the bin ;)

Are you joking? This will retail at ~500 euros. Just being able to replace the battery easily means it might last 5 or more years versus just 2; typically rechargeables lose their charge after repeated use; they're not eneloops :).

Incidentally I had to have my Samsung screen replaced due to a defect - they automatically have a 2 year warranty - so I just took it to a Samsung registered service centre and got it done for free. They bill Samsung. They wouldn't have been able to do that if it had been hard to repair. They'd have had to send it to Samsung lab, like they have to do for motherboard replacement, meaning 2 weeks without the phone.

Just because some companies decide to make integrated batteries, does not make it the smart or wise choice and battery driven electric cars all have replaceable batteries.

If battery driven electric cars have replaceable batteries, then so does EVERY battery powered electronic device ever made, including the iPhone - because just like the iPhone you are going into a dealer to change out the VERY LARGE battery pack in an electric car.

It's great to hear that the S4 is easy to repair.

Hopefully Samsung will be able to provide a better repair service than they currently offer. My S3 is currently challenging their technicians, although I am starting to suspect they are targeted on turnaround rather than whether it works or not when returned.

Three mobile have become so frustrated with Samsungs repair capabilities that they have taken themselves out of the loop and insist that customers grapple with Samsung themselves. They refuse any loan phone during the painful process no matter how many phones or how good a contract you have with them. Bear this in mind when choosing your supplier.

Interesting observation. If the repair is under warranty (i.e. the phone developed a fault, not that you dropped it), then your claim is against the supplier, it is their porblem, and they can not fob you off with the manufacturer.

I think the removable battery is great.
Most people who have cell phones do NOT have multiple batteries for them. You use the battery that's in the phone until it starts to die, then replace it.
With devices with integrated batteries- you have to toss out the device.
It makes no sense to throw a whole device out- one that may still work perfectly and still suit your needs- just because the battery wore out.

Agreed. But the manufacture of electronics is so ecologically destructive that none of the phone companies want to get into that conversation. They lose no matter what.

Well, a device like the Nexus 4 apparently only requires removing a couple of screws to get at the battery. If changing the battery is just a one-off when the old one dies, then that level of accessibility is fine.

The only thing about removable batteries is: customers probably won't recycle them properly. I would imagine no more than 20% would take them to a proper storage facility. Most will end up in landfills. I can't see how that is more 'green' than having the company recycle the parts for you. Time-consuming yes, but certainly more green.

That's not certainly something new.

@shigzeo
If one doesn't know that a battery should be disposed in a certain way, then they will also throw their iSomething in the garbage.
That way your hypothetical landfill is also full of smartphones (and all the related elements and more or less harmful metals) in addition to the batteries...

Yes, exactly.
I take really good care of my devices so I get years of service from everything I buy.
My current cell phone is a 6 year old Motorola. It's built like a tank, and I'm on my 4th battery. I'll keep using it until it either dies, or I finally decide to upgrade to a smartphone.

although, I have to wonder how many people even stick with a device for so long that the battery goes out. I feel like most people upgrade or something before the battery starts to fail.

Exception for me being my unreliable 2009 white Macbook...little failures everywhere, including a short lifespan battery (without huge numbers of cycles either). Also a cared for adaptor that broke (costs almost as much as the battery to replace, stupid), and chipped off wrist rest area (which apple at least repaired that for free, after i showed them a google search revealing how widespread the problem was).

I digress...

The reality is that you can use an iPhone for 2-3 years and never replace the battery. Meanwhile, with replaceable batteries I was having to replace them every six months with older cell phones...

So why is it an advantage that you have to replace batteries and in the real world I never do? I'm still using a 3Gs on the original battery from time to time!

Also you are throwing out your dead batteries, where if I had to take a phone into Apple to replace they also would recycle the battery for free.

How is the removable battery a boon to the environment? It promotes copious consumption. People will be multiple back-up battery and never use them. When the phone is outdated all will be throw out. It is not like you can drop in a S3 battery into S4 or S4 into S5.

Integrated battery last longer because it is less affected by the environment and never really discharged. They are also more likely to be recycled with the phone than just sit in a drawer somewhere.

Who buys multiple batteries just to put them into a drawer and forget about them? You seem to trying to describe a downside that does not exist.
My phone has a replaceable battery - I certainly have not bought a second battery, but if the original one starts to fade then I will, and so I will put back the day that I have to buy a new phone - big green win. And the old battery can be easily sent to a proper recycling facility.

The HTC HD2 was originally a Windows 6 phone but devs hacked it to run many versions of Android, Ubuntu, Windows 7, Windows RT and other systems a well. None of this would have happened if the phone couldn't age. And irreplaceable battery phones don't age well at all.

With replaceble batteries the phone will not be outdated. I use a phone at least for 5-6 years.

A battery is a battery, integrated or not. All batteries needs to be replaced sooner or later and integrated batteries aren't less affected by the environment as opposed to user replaceables. When your integrated battery dies and you have no chargers available you're essentially dead in the water while someone else just changes theirs.
