The CAT S52 has slimmed down considerably so that it no longer passes for a chubby outdoor phone but more for a fancy smartphone with special skills. However, only a small battery fits into the well-protected case. In the review, we look at how this affects the suitability for everyday use.

Nice, thorough review otherwise but I think the comment on S52's connectivity is misleading. Had to go back on the manufacturers specs to check: while 10 LTE bands is fewer than in the more expensive models, it sure is more than "a few". Pretty normal range for non-outdoor phones as well ,and e.g. one of the most expensive phones on the market, Samsung S10+, has 12 LTE bands for example...
