Phone's touch screen wouldn't respond reliably when plugged into the charger I keep at work. Noticed a lot of noise in the 35kHz range so I put in a 1000uF electrolytic and a 10uF MLCC to help reduce the noise. Phone touch screen has no more problems now.

Edit: This is the charger in the picture. After seeing the pictures where it caught on fire I think I might ditch it. Makes me wish I would have upgraded the piece of aluminum foil they call a heatsink on the regulator when I had it open and free of hot-snot.

tl;dr New phones need more amps than old phones. Since older phones didn’t need much power their chargers were designed to only deliver that little bit of power. An old charger won’t be able to keep up with a new phone’s power demands so it’s going to charge slowly.

Non-tl;dr version:

The S4 has an extremely complex charging circuit inside the phone and your charge time will be slow if everything isn't just right. First, some basics, then further down some details about the S4.

A charger will give any amount of amps up to it’s rating, so if the tiny letters on the charger say “Output 5V, 1A” then the most it can deliver is 1 amp of power. Compare it to the wall outlets in your house. They usually have breakers on them that are rated at 20A or 30A. If a radio has an input rating of 120V, 0.5A you can safely plug it into a wall socket rated at 120V, 30A. The outlet can’t force your radio to take 30A. It just sits there and hands out what it’s asked for until it reaches it’s max.

It’s important to understand that the output rating of the charger is only the maximum available. It is NOT how much power will actually enter the phone. If the phone only wants 0.1A then the charger will only deliver 0.1A, even if it's rated at 1,000,000 amps. The key is that the charger has to be rated higher than the device being charged, and it doesn't matter at all how much higher.

The Galaxy S4 pulls 1.5A at the most. The simple part is that most older phone chargers can only do 1A, so the phone is going to charge slowly on them.

After that, it starts getting complicated. It looks like the S4 has circuitry that can detect a shielded USB cable. Both the charger and the cable have to have the proper shielding for it to request 1.5A of power. It looks like if it doesn’t see the proper shielding then it reduces how many amps it asks for which makes it take longer to charge. This is most likely to prevent small thin USB cables from getting hot or catching fire.

To guarantee maximum charging time, stick with chargers sold or approved by Samsung for the S4. If those are too expensive then get something like this: http://www.amazon.com/PowerGen-Charger-Designed-Android-Devices-/dp/B0073FE1F0/ref=sr_1_2?ie=UTF8&qid=1374886700&sr=8-2&keywords=usb+wall+charger

The description says:
>Input:100-240V 150mA ; Output:DC 5V 2.1A Max. or 10W (A combined total of Max. 2.1A).

That means if you only plug in one thing then 2.1A of power are available. If you plug in two things then they have to share the 2.1 amps. If you use one of these just make sure you use a good, thick, shielded USB cable and only use one of the sockets.

I recommend this one. Good quality, cheap, charges my n7 fast. http://www.amazon.com/gp/aw/d/B0073FE1F0/ref=ya_aw_oh_pit

If you can get your hands on a laptop hard drive or ssd that would solve your problem. You can also get a Y usb cable to provide additional power (http://www.amazon.com/Apricorn-Power-Adapter-Cable-AUSB-Y/dp/B000JIOHDE) with a usb power supply (http://www.amazon.com/Powergen-2-4-Amp-Charger-Designed-Android/dp/B0073FE1F0/ref=sr_1_2?s=electronics&ie=UTF8&qid=1417877055&sr=1-2&keywords=usb+power+adapter)

Here is another option. Get a power strip or power squid and load it up with chargers like this one. http://amzn.com/B0073FE1F0

This is more compact and IMO the best wall charger brick. It has a 2.4A and 1.0A port while OP's only has a 2.1A and 1.0A.
