Default [Q] How can I get a faster charge from USB in my PC?

My Galaxy S4 charges.... terribly directly connected through USB into my PC in both USB 2.0 and USB 3.0 inputs.

Am I doing something wrong, is there a way to boost the charge you get from a USB PC input?

Thanks!

Most USB ports on a computer are only 0.5 to 0.75 amps. To charge your GS4 you really need about 1.0 amps, the charger that came with your GS4 is 2.0 amps. So no you can't get a better charge from your computer.

Check the logo on the USB ports. Look for one with a lightning bolt. My laptop has specified ports that have higher output for charging.

Some laptops from MSI are supported by their utility called Super Charger. This boosts the power output but also removes connectivity (I believe). So you won't be able to connect your phone and transfer data.

There maybe be a utility that supports your laptop for boosting charging. Best thing to do is Google around for some programs.

If your laptop is old you're probably out of luck.

There is a cord that is used for external hard drives on laptops it uses two usb ports but plugs into one drive doubling the power. Just a thought. Only thing is they are usually mini usb not micro but an adapter should do it

Thanks all! I also have another problem!

I read your answers, so I decided to get a 3 amp car charger for my S4! If the original S4 wall charger is 2 Amps, then a 3 amp car charger sounds good, right?

Unfortunately, my phone gains no charge from it in both of my cards, my phones battery just dies slower when plugged into the car.

Any tips? Thanks!

Most car chargers lie about their ratings so that could be one problem, the other, is most phones see car chargers as a usb port charger instead of an ac charger so the rate of charge is automatically reduced to usb charging. Somewhere on here was a thread on how to modify a car charger so the phone would see it as an ac wall charger and allow it full output. I believe you have to open up the charger and jump a wire over. Search on here or google it and you should find it.

Could be a lot of things. But remember you phone will only allow its self to charge at a certain rate. Thus, purchasing high amperage chargers will provide no benfit.

High amperage chargers are more for tablets that require more power for their larger batteries.

Mine does that. I have to reboot it while it's plugged up to my car charger. Thought my charger was bad after taking the MJA update. Still looking for a fix....
