    Anyone notice how quickly the battery seems to recharge? BTW I am getting great battery life considering that I am constantly playing with it. Maybe the fact that I'm coming from the Evo 4G, which had a horrible battery life, has something to do with it.

    It's amazing. One of the phone phones with a great battery life. Only the Note 2 surpasses it.

    But it charges incredibly fast.

    Qualcomm Quick Charge technology:

    AnandTech | Samsung Galaxy S 4 Review - Part 1

    "The graph below shows the benefits of using Samsung's own charger vs. a standard charger that implements the USB BC 1.2 specification. When used with the bundled charger, the Galaxy S 4 recharges much faster than HTC's One, despite using a larger battery. Obviously the Galaxy S 4 will charge with any USB charger, but the charge time will simply be longer. Samsung uses a voltage divider and signals the presence of their own charger by sending 1.2-1.3 V across the D+ / D- pins, this is similar to what Apple does with 2.0 or 2.8 V across the pins for various USB chargers they've shipped over the years. This signaling is essentially Samsung's proprietary tablet charging signaling which they've employed on the Galaxy Note 2 and now SGS4, in fact the two use the same exact charger, so it's worth tossing out your old ones and getting the appropriate one to take advantage of the faster charging."
