Hi Rammonhan,

Depending on whether you are using a powered usb hub or just the usb jack from your computer, the rate of charge may vary. Generally, a usb charge is slower, and is known as a slow trickle charge. That is actually better for your battery than a faster charge. Fast charges can heat your battery and literally reduce your battery's lifespan, or ability to hold a charge, all for the sake of convenience.

It should be as safe to charge your device from a USB source as how reliable your computer regulates it's voltage, which is 5 volts. So, that really means it should be safe.

Hope that helps

Something else to consider is what you are doing while the device is charging. If you are doing something like heavy gaming, or watching a movie, the slower charge from a USB jack on a computer may not be able up keep up with the power demands of both charging a battery and running the device full tilt.

So, when I charge my device, it's usually turned off, unless i have important texting to do, LOL, or I need access to by battlenet authenticator...LOL

In general, try not to use your device heavily while USB charging, and you'll keep your battery tip top.

Exactly what I would of said, I second everything Justin has stated, & just to add to the latter It's recommended you don't use your phone while it's charging because it puts strain on the micro USB connection on your phone & can break it very easily if bent or twisted slightly. over tame it will break the connections within the phone & then you'll have to send it for repair & since it's physical damage chances are it will not be covered under warranty. You'll be stuck paying for the repairs out of pocket.

I found this article to be a good explanation of USB charging. Worth a read if you still have questions.
