It’s not often that Caterpillar is beaten handily by competitors when it comes to power.

But that’s exactly where the company’s smartphone lineup finds itself. However, it’s not exactly due to a design failure. It’s more of a consequence of trying to find the right mix of features for the customer.

The company has a three-device lineup now with the B15Q, the snappier upgrade to its original smartphone the B15; the sleeker but slightly more fragile S50; and the new best-of-both worlds S40.
