never confirmed by Verizon, it seems likely that battery life (or more accurately, the lack thereof) played a part in the series of delays preceding the Thunderbolt's launch. To combat this problem, Big Red and HTC are offering a rather unsightly extended battery pack that nearly doubles the handset's capacity from 1400mAh to 2750mAh. All that extra juice will certainly come in handy for folks leaning heavily on the phone's LTE radio. However, the device costs $50 and adds an ounce of junk in the trunk -- on a device that isn't svelte to begin with -- so why not buy another standard battery for ten bucks less instead? Then you can use the Qi-compatible back and induction charging station Verizon's releasing in April -- both are pictured after the break. It's just under $100 ($29 for the back and $69 for the pad) for those who want to cut the cord and don't mind the expanded waistline we assume comes with the privilege.
