The HTC Inspire 4G comes equipped with a removable, 1230mAh Lithium-Ion battery – despite its diminutive size, the manufacturer touts up to 372 hours (15.5 days!) of standby time and up to six hours of talk time.
The Inspire 4G also comes equipped with HTC's Sense-ified Wi-Fi Portable Hotspot, which can be accessed via the Quick Settings under notifications or directly from Settings > Wireless & Networks and connect up to eight users at once.
USB tethering is also available as well as Internet Pass-Through for using your home broadband with the Inspire 4G when Wi-Fi isn't available – advisable given the handset's poor 3G/faux 4G data speeds.
Bluetooth 2.1 with A2DP and EDR is also included and we had no problems pairing to our Microsoft SYNC-enabled automobile; the phone also supports FM radio reception through a dedicated app when headphones are plugged in (which then act as the antenna).
