The fragile link-up between EV-DO and LTE make handover occur a lot more than it is supposed to, which eats battery life even more. With AT&T and T-Mobile using an HSPA+ network alongside LTE instead of CDMA2000, handover operation is a lot smoother. As far as battery life goes, it should be slightly better than Verizon and Sprint LTE phones because LTE supports fast handover between UMTS and LTE. AT&T LTE phones are normally not forced into active dual-mode operation because HSPA+ lets you use data and talk at the same time. As a consequence, AT&T has no need to force the device into active dual-mode operation. However, battery life will still be pretty bad because LTE signals are still very weak in most AT&T LTE zones, and AT&T LTE devices default to connecting to LTE signals whenever possible.
Speed is of course the big advantage, with potential advancements of ten times over 3G rates. The fourth generation of mobile communication Gs & LTEs: Understanding Mobile Broadband [Technology Explained] Gs & LTEs: Understanding Mobile Broadband [Technology Explained] Connecting to the Internet was once all about big honking cords. The cords might be telephone lines, or cable lines, or FiOS lines specifically installed for Internet service, but the running theme is a line... Read More is still evolving, and we’re bound to see new standards, speed increases and coverage benefits in the next few years.

Although, there are grave negative impacts of using cell phones during driving it is pertinent, for the sake of arguments, to present benefits also. The most important benefit of cell phones during driving is again the security factor. During emergency situations cell phones can provide help and driver can make emergency calls, even reporting any dangerous scenario such as roadside accidents. Through cell phones a driver can locate the desired route. Furthermore, using FMs on cell phones can provide information about weather and traffic. (Sturnguist, 2006)
