The Infuse 4G has a 3.7-volt, lithium ion, 1750mAh battery. At 8 hours talk time, it's slightly worse than the Galaxy S2 and a handful of other Android phones with smaller screens and 1800mAh batteries.
Even so, we were pleasantly surprised with the phone's battery performance (not to mention the favorable standby time). After all, that's a big screen to light, and it'll still outlive any LTE phone on the market (provided that LTE is turned on).
Adding media is as easy as popping out the hidden micro SD or connecting the phone to a PC. But if fidgeting with hardware isn't your style, you can also use the phone's included AllShare which is Samsung's free software which will allow you to wirelessly access files from your computer - provided you don't have a Mac.
In order to tether the Infuse 4G, you'll need to sign on for an additional tethering (or mobile hotspot) plan and travel deep within Settings to access it. The Samsung Infuse 4G supports 802.11.n, Bluetooth, GPS and the usual wireless standards.
