Reviews summary

Based on 9 reviews

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."

Rugged handset impresses with durability, but it's an unlikely smartphone

from The Inquirer
For those looking for a sturdy, rugged phone, we wouldn't hesitate to recommend the Cat B15, as the handset excels at fighting off the elements.However, for those actively looking for a rugged handset with smartphone features, we're not so sure the Cat B15 would be our first choice. While it runs Android 4.1 Jelly Bean and features all of the usual Google features, the dual-core 1GHz processor and 4in WVGA screen make operating the software often frustrating, with the phone experiencing lag and displaying dull colours due to its low resolution display. ..

The durable smartphone with nine lives

from Know Your Mobile
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. The CAT B15 stands out from other durable phones because of its touch-based smartphone functionality, making it a good option for those in fieldwork. However, other smartphone buyers might prefer a handset that looks nicer, with improved performance, connectivity and camera capabilities... Full review

The Cat B15 feels more solid in the hand than many, and might withstand a few more knocks and drops

from ITProPortal
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 Cat B15 feels more solid in the hand than many, and might withstand a few more knocks and drops, but its poor screen is a letdown, it is bulky, and the fact that I was able to let water into my review sample by forgetting to secure the backplate properly is a worry...

This is for everyone who has ever dropped a phone

from Coolsmartphone

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 standard phone with a whole load of rubber wedged on, this has been designed from the ground up, and it shows. This is a phone that you can run your business from while you’re listening to the built-in FM radio. This is a phone with two SIM cards so that you can have your work and home lif... Full review


It's unquestionably one of the best rugged handsets we've looked at

from T3
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 give the B15 scope for customisation, and basic necessities like Bluetooth and GPS are included... Full review

The Cat B15 looks like nothing you’ve ever seen before

from Mobilephones
You might be more familiar with seeing the Cat logo plastered across building sites, on diggers and machinery with the recognisable black and yellow branding. However, Cat has started to break into the mobile phone arena by offering a range of rugged smartphones for use by, well, anyone who has a tendency to drop, dunk, or scratch their phones on a regular basis...

Using the Cat B15 just makes you feel that bit more manly

from TrustedReviews
Like eating a Yorkie while driving an 18 wheeler, using the Cat B15 just makes you feel that bit more manly. In fact there are plenty more reasons to like this phone as it looks good by ruggedized standards, comes with the silky smooth Jelly Bean Android OS and has a half decent camera and good battery life. However, its spec is a bit disappointing given its relatively high price tag and the way the battery sometimes pops out when it's dropped onto a hard surface is a bit worrying... Full review

It will appeal to builders and other burly workers who want to enjoy swiping at apps

from Cnet
The CAT B15 is water, dust and shock proof, but unlike some tough phones it boasts a 4-inch touchscreen and Android Jelly Bean software. It's strong enough to put up with a tough life on a building site, while letting you enjoy apps and games from the Google Play store when you've finished constructing things... Full review

I hate this phone because it is crap.

Do not let them fool you, this phone is not so tough as they claim , it's processor is very slow, it not user friendly, the battery does not last longer than other smart phones, it is definitely not water or even damp or splash proof. I got the new B15 Q in February 2015. I am a farmer and us... More
Do not let them fool you, this phone is not so tough as they claim , it's processor is very slow, it not user friendly, the battery does not last longer than other smart phones, it is definitely not water or even damp or splash proof. I got the new B15 Q in February 2015. I am a farmer and use my phone a lot outdoors as what the B 15 Q is intended for. The first time I got caught in a rain storm it was inside my rain suit and only got a bit of dampness-stuffed! Buttons doesn't respond, switches on and off, phones anyone randomly. Fell once off my bed, completely stuffed, doesn't even come on anymore. Absolutely a crap, waste of money. Don't buy it. Less
