    So, I found an old battery for my Samsung Galaxy S4, and i started re-using it. But I think it drains little bit fast.
    So I'm wondering, what's the normal rate for battery draining while using Samsung Galaxy S4, in other words how much of percentage of battery is lost, maybe per 15 minutes or per hour WHILE using the phone (going trough apps and stuff)

    Welcome to Android Central! Battery life depends on lots of different factors, as I'm sure you're aware. It looks like the S4 will generally give anywhere from 3 to 5 hours of total screen-on time. If you're actively using your phone, that means the screen is on, so 3-5 hours of total screen-on time translates to a battery drop of 20-30%/hr, or 5-7%/15 min.
