Would you buy a smartphone that's thinner than 5 mm?

In the race to create the world’s slimmest smartphone, manufacturers are seemingly forgetting that they shouldn’t eliminate (or compromise on) essential features just to push the boundaries of thinness a little bit further than their competitors.

iPhone 6, Samsung Galaxy Alpha, Samsung Galaxy A5, Samsung Galaxy A3 - these are all very thin smartphones (under 7 mm), but they’re still thick enough to accommodate a 3.5mm headset jack. However, even thinner handsets - like the 4.85 mm Oppo R5 (pictured above), or the 4.75 mm Vivo X5 Max - are simply too skinny for this, thus leaving out a feature that not many smartphone users can live without. Sure, the Oppo R5 ships with a USB-to-3.5mm audio adaptor, but that’s not really the same thing. There's a couple of other problems with ultra-thin handsets: their batteries can’t be too large (likely not being able to last long on a single charge), and their cases are more prone to bending following normal usage.

With all this in mind, we want to ask you if you’d buy a smartphone that’s thinner than 5 mm - assuming you could do it without having to import it from another country. Cast your votes below, and weigh in in the comments if you have more to say about ultra-thin handsets (either in their defense, or against them).

Once there was a poll asking would you buy a phone over 4" display... Definately i love the thinnes with sturdiness...

Thinness is great as long as the device have great battery life and doesn't bend.

I'd rather it be 8 mm with 2x as much battery Even if the 4 mm phone has a 3000 mAh battery, if it were 8 mm it could have 6000 mAh

Probably more than that, considering the other components probably wouldn't also double in thickness.

Plus it doesn't feel like crap in the hands. There is something to be said about ergonomics and thinness doesn't help that too much.

You can use stronger materials as they become cheaper in the future, ie there is one type that's thinner than human hair and stronger than steel.

If the phone doesn't bends I wouldn't mine but I think 4" mm is just pushing it

Who cares? Phones are already thin enough. They need to focus on keeping phones reasonably wide from side to side. (left to right). Anything wider than the Samsung S4 (70mm), and I can't reach my thumb across the screen. Frankly, 66mm is the perfect width.

Thinking like that everything will just end up looking like an iPhone. The more variety the better, we need go back to the good old days of feature phones where everyone can get something that suits their exact needs. And this is an example where some people may not care about 3.5mm audio jacks, instead would rather a slimmer profile.

Yes, true .. I've had a Galaxy S4 and it's handling was better than my current Galaxy S5 .. I guess they should trim the S series back to 70mm

i dont know if anyone gets what i am saying but technically if you have a thinner smartphone wouldnt there be more "hand" to go around and reach the other side

Obviously everyone here (the haters that populate this site) vote no. UNTIL your beloved phones come nice and elegantly thin, then you'll stop preaching your hate lol. #fanboyism

I'm samsung fan...and samsung has phones in sub 7mm category.. And still I hate that.....i don't like thin phones...s4 was prefect I think both in size and thinness... I hope s6 gets back to that size... I don't need waterproof, fingerprint scanner or heart rate monitor I just want a phone with s4 footprint....

I don't like a thin phone because they feel like crap in the hand. Unless it's a small screened phone, your hands stretches across the width but if there isn't any curve in the middle, your hand strains. That was the reason I didn't go with the Droid RAZR when it came out, it wasn't comfortable to hold. And it was the thinnest smartphone at the time. On top of that, with the current level of battery tech, that means shortened battery life. The only thing a thin phone is good for is slipping it into tight jeans. If you're a guy wearing tight jeans, you've got more problems than I care to discuss here.

no thanks, typing was already uncomfortable on a iphone 4 ... a ultra thin smartphone would feel like holding a razor

if the battery is above 3000 mAh, then yes.

It's just not ergonomic. My Droid Incredible 2 felt amazing in hand and it was like 10-11mm. Plus, if they make a phone that thin, it means they ate compromising on specs. I think some of the advances that come from making thin phones are great but overall it's stupid to build a 4mm phone with a XXXX mah battery when you could build one with twice the capacity at 7-8mm.

Too big of a compromise right now. But if they managed to doe everything right, why not? But no for now

As long as phone has a sturdy construction...a good battery life and optimised cooling mechanism..then it is yes for me..!!

There is no reason for thme to bend and most very thin phones are using a lower power SoC so no reason for battery life to suffer. This is as dumb as asking a few years ago if you would buy a phone thinner than 10mm

battery and camera is much more important than thickness

if thinnes means less essential features, then, the answer is No !

There should be a 3rd option "I could care less about how thin it is"

32. Beijendorf unregistered

Couldn't care less* Saying you "could care less" makes no sense as it implies you care somewhere between a little and a lot and therefore could care less than you already do.

I have the Blu Vivo IV and it is a decent phone despite having no LTE.

I have no immediate attitude towards the thickness or thinness of a phone except for the structural challenges it brings. If they could make a sturdy 2 mm phone with excellent battery life I'd take it. Today I charge my Lumia 1520 with QI charging and use Bluetooth stereo headsets, so plugging it in physically isn't the issue it once was, particularly if they get cloud management even more flexible...

The problem with a 2mm phone is that it would be like holding a large credit card, your hand would strain after holding it for too long.

Thinness doesn't matter to me at all. Weight however does matter a little and if it's thin it's generally a little lighter so maybe in that sense it matters. However these new phones where you can't even have a headphone jack and there's no room for a big battery without widening the phone's surface area, that's going too far. I don't think valuable features should ever have to be sacrificed just for the sake of thinness. If a phone can have minimal bezels, be waterproof, have a long lasting battery, and be thin all at the same time, I welcome that device. Part of me thinks companies should wait until the technology is there to build such a device, but then again if everyone goes thin it'll mean more people trying to figure out out to get better battery life in such a thin body so one day battery life won't have to be sacrificed.
