After a little delay, No. 2 phone maker Samsung finally gets into Verizon's Droid franchise and continues the robotic theme for another year. The Droid Charge runs on Android 2.2, or Froyo, has a 4.3-inch LED screen and is powered by a 1-gigahertz Samsung Cortex A8 processor. According to analysts, Samsung has built the phone to consume about half as much battery power than its 4G LTE predecessor, the HTC Thunderbolt. Another area where it exceeds the Thunderbolt is on price. Verizon has a $300 price tag on the Charge, with a two-year contract compared to the $250 price for the Thunderbolt.
