I thought the so called "test" is quite meaningless since it doesn't provide any useful information, such as at what temperature it stops working etc. I don't find myself any wiser after watching the video. May be the next meaningless test they can consider is to put some of them in a nuclear reactor!

Michael B 66: 10Wh battery for smart phone = 36000 Joule energy (1 day)
70Wh capacitor: roughly 250000 Joule (as proposed in article for 7 day power)

Recharge in a few seconds: Let's say 5 seconds - you need a 50 kW power supply to do that. At 10% loss you have 5kW heat. What does it mean?

Charging: 50 small cooking plates at the same moment
Heat: 5 small cooking plates heating the smart phone for 5 seconds - it will glow!

DavidfotosDotComs Idea to load a spare cap and replace it is the better idea!

In addition, to deliver 50kw of power at 5v (assumption) you would need cable and connectors that can withstand current up to 10,000 amps.

Melchiorum: It's kind of baffling to read all the sarcasm-filled and hateful comments. Obviously, it was a challenge project from the beginning and it's not about competing with real commercial cameras. Such projects aren't about "perfection" or "quality", they are about exploring the possibilities of what can be done using very limited and unconventional means.

The dude has PRINTED a working camera. Lens included! It's amazing! Of course it has horrible image quality, it's to be expected - no one has ever done this before. Yet here they are, snarky bitter, sarcasm-filled comments, that somehow get up-voted.

Jesus christ, people, how much more sad can you get? Can you even feel joy or excitement for anything anymore or is arguing on the internet has sucked out the last bits of your soul?

The amount of "Like's" that you have gotten suggests that more readers are thinking like you than the others! Cheers...

Francis Sawyer: So Apple stabilized the lens that needs it LESS.

You know what? Apple should just remove the lens from the camera. I mean.. lenses are "old" technology, just like the headphone jack. Then they could sell a lens dongle, to "adapt" the camera to taking pictures. Just like the headphone dongle adapts the music player to play music.

May be Apple should discard the century-old technology -- the phone function itself! They can always offer a lightning-port-handset-attachment so that you can use the "old" technology if you are not "advanced" enough. Millions would be so proud to own one as it would make them feel very "advanced". Most importantly such innovation must be from Apple, Hallelujah!

On article Class 10 200GB microSD card on the way from Lexar (71 comments in total)

"Enables users to capture more than 17 hours of HD video; 33,000 photos; or 28,000 songs"
Why do they keep using this kind of meaningless numbers. There are so many variables in those numbers. Wouldn't making such claims just make them look like they have no idea what they are talking about? 200GB is 200GB, people who buy such cards know what it means!

Autofocus is 92!? It should be 100 for a phone camera! May be 99 if you wish to play safe.

hotdog321: Nice, but unless Samsung puts back the replaceable battery and water proofing like the S5, this is a total non-starter for me.

More important to me is external micro SD card!

Miki Nemeth: I used to be a Sony fanboy, I still use Sony cameras, but I've switched to Samsung Galaxy Note 4/Edge just because of S-Pen. I'd expect active/digital/Wacom pen-support from such a beast.

Samsung could have done a better job in their design but such incidents may be as unlikely as someone accidentally put a condom on his testicle. Anyway many have since learned that you can easily remove the pen but inserting a strip of plastic or paper on the inner side of the pen to release the catch. Don't put it out by force, as it will hurt!

How about looking up and down since it is meant for VR recording?

Wye Photography: I think I prefer the AGFA Syncho box camera (I have one somewhere - almost forgot about that).

Here are the "advantages" of the AFGA

1) Mine cost £1 on the bay of e
2) Don't have to worry about focus - no focus, its fixed.
3) Only two apertures from which to choose.
4) Built in Yellow filter.
5) out Holgas a Holga
6) out instagrams instagram
7) No need to worry about shutter speed, there's only one.
8) No contract needed.
9) No one would want to steel it.
10) Don't have to worry about IQ, it's just crap.
11) You look less of a prat using one than using a tablet.
12) Can't see, no worries, neither can the AGFA.

No, seriously, although I don't like Android the IQ of the S5 looks pretty good.

I buy junk and sell antiques. Some fools sell, some fools buy!

AbrasiveReducer: If this could be adapted to an electric car battery it would be really be something.

May be with a laser guided lightning strike the car would be fully charged in a split of a second!

Samsung S4 battery is 2600mAh. To fully charge it in 26 seconds the minimum charging current would be 360A regardless of material used. 360A is more than a typical current draw when cranking a car. The cable used has to be at least the size of car battery cable, which gets hot when cranking for too long. A typical USB cable would evaporate in a split of a second! If the charging voltage is 5 volts you would need a 1.8KW (360A*5V) charger! Current S4 charger is about 10W!
