Battery power and other internal features. Amazon says that the Kindle Fire's battery will provide you with eight hours of continuous reading and seven-and-a-half hours of continuous video playback as long as the wireless connection has been turned off. Speaking of the wireless connection, the Kindle Fire is Wi-Fi-only for the time being, so it doesn't have any LTE, WiMAX or HSPA+ connectivity and thus isn't associated with any wireless carrier. As far as processing power goes, Amazon is only saying that it's a dual-core processor but hasn't yet told us the manufacturer or its clocked speed. It seems as though we'll have to wait for iFixit to perform an autopsy before we know for sure. The device also has 8GB of internal storage.
