4G is a battery vampire -

People testing smartphones using 4G are finding that it is a vamp when it comes to batteries and not in a good way.

Verizon's 4G network is covering a good chunk of the USA with AT&T gaining ground. But, because 4G coverage isn't continuous in many locations, batteries are taking a big hit.

According to the Wall Street Journal it is impossible to find a battery that lasts longer than a day because in areas with spotty 4G service, the phone spends an awful lot of battery power trying to hunt down a signal.

While it is possible that improved networks will help fix the problem, things will get worse as more services which are based on 4G become available, such as streaming video content.

According to Consumerist, the only one which seems to do OK is the Razr Maxx which, after a full day of moderate-to-heavy use on Verizon Wireless' 4G LTE network, still had 75 percent of its battery power.
