Mous Limitless 6.0 vs Otterbox Defender: which is the best phone case?

We dropped, smashed and pushed two of the best phone cases to the limit – find out which one cracked, and which one didn't

I used to think that finding the best phone cases was for the overcautious. Then one afternoon, my phone slipped from my hand while I was in the loo and smacked onto the floor. That was the moment I understood that a phone case isn’t just about protection – it’s also about avoiding the embarrassment of explaining how your phone met its maker.

To find the best phone cases, we pitted two bestselling models against each other: the Mous Limitless 6.0 and the Otterbox Defender.

Our test included dropping them from various heights, smacking them on all sides, and giving the screens a few whacks. We even spilt ink over them to see how easy they were to clean, and checked whether they were simple to fit and remove. Finally, we tested whether they interfere with your everyday ability to use your phone.

How did the two cases cope with our test?

Our tests are physically tough, but we also check the basics: is the case easy to fit and clean, and comfortable for daily use?

The real test, of course, is whether it can take a hit. Before each round of testing, we fitted a fresh screen protector so any cracks could be blamed on that case alone.

Then came the drops: about 30 in total, on every edge, corner and face of the phone, from sitting height, hip height and chest height.

One of the two cases walked away unscathed. The other... not so much.
