PC World - If the Motorola Droid Razr Maxx ($300 with a two year contract from Verizon; price as of 1/27/12) looks familiar, that’s because it is virtually identical to the Droid Razr. The big difference between the Razr Maxx and the Razr is battery life: Motorola claims that the Razr Maxx gets 21 hours of talk time on a charge. One of the weaknesses I found with the original Razr is that battery life drained rapidly over Verizon’s LTE, a common problem among the carrier’s fleet of 4G phones. Are Motorola’s claims true? Does the Droid Maxx’s battery hold up over 4G? While we didn’t finish talk time testing in time for this review (we will update once it is complete), the Razr Maxx’s handled video streaming and gaming over LTE with very little strain on the battery.
