Informr score
The CAT B15 currently has an Informr score of 5.4 out of 10. This score is based on our evaluation of 9 sources including reviews from users and the web's most trusted critics.

What's good

  • Water-resistant, dust-proof, survives drops of up to 1.8 meters
  • Wet finger tracking display
  • Good battery life

What's bad

  • Mediocre display with bad viewing angles
  • Lag when using processor intensive apps
  • Battery cover and battery pops out when dropped
  • Small internal storage

The makers of Caterpillar have crossed over from construction equipment to smartphones with their release of the CAT B15. Like most Caterpillar machines, the CAT B15 is an especially rugged device and comes with IP6 and IP7 certification. This means that the phone is waterproof up to 1 meter for up to 30 minutes, completely dust-proof and can survive drops of up to 1.8 meters onto concrete. Expert findings support these claims, but they also mention that while the device comes out unscathed when dropped, the battery cover and battery often popped out.

Due to its' ruggedness, the CAT B15 is much thicker than the average smartphone at 16mm. While the rubber bumpers and aluminum protectors help shield it from drops, they also add to the phone's width and height. Trusted Reviews calls the phone a "chunky unit," but also notes that it is not uncomfortable to use for the most part.

The rest of the phone is not nearly as impressive as its survivability. The 4-inch display offers a mediocre resolution of 800x480 pixels and is protected from scratches with a coating of Gorilla Glass. Most reviewers were unimpressed with the screen noting a lack of sharpness and poor viewing angles. It does, however, sport a new feature that many critics enjoyed called wet finger tracking. This allows the phone to still recognize touches and swipes even if liquids splash onto the screen.

Under the tough exterior of the B15 is a 1GHz dual-core processor, 512MB of RAM, 4GB of internal storage and a 2,000 mAh battery. In terms of performance, most critics found that it worked well in day-to-day usage. T3 states, "…This unmodified, unskinned version of Android practically flies as you navigate…" Unfortunately, reviewers did notice some slow down and lag when using more processor intensive operations. Due to the lower specs and display resolution, experts found that battery life was quite good, lasting around 2 days of mixed use and a full work day when utilizing 3G.

Despite the lowered specs and display, reviewers were overall impressed. Cool Smart Phone says, "This is the most feature-rich 'tough phone' I've ever reviewed." Clove adds, "The CAT B15…lives up to the promise of a tough handset…It's definitely the best of the lower end rugged devices."

The CAT B15 is a perfect fit for someone with an active lifestyle or a job working on a construction site if durability is your one and only concern.

Caterpillar clearly thinks there's a point in continuing to update its line of rugged hands, but I'm not so sure that plan makes sense. These days, mainstream handset makers do rugged quite well, and Caterpillar needs to offer more than they do in order to compete successfully. It is true that the C...

This is the most feature-rich “tough phone” I’ve ever reviewed. Sure, the specification isn’t-quite-as-high as your mates’ Galaxy S4 or HTC One but this has survived drops, survived a swim in the bath and it actually looks good too. This isn’t “just” a...

- Leigh Geary, Coolsmartphone

The CAT B15 is a niche handset and, as such, is very easy to pin down for a verdict. It's unquestionably one of the best rugged handsets we've looked at and will stand up to the rigours of outdoor usage whatever the weather. The inclusion of Jelly Bean and the versatility of the Google Play store gi...
