Irks me that not one single phone manufacturer dares to ship a product as indestructible as an iphone in an Otterbox. Sure it would be the clunkiest handset in the store, but compare it to other phones + case, there's room to make a superior final product. But no. Apple keeps shaving millimeters and Otterbox keeps slathering them back on.
After a normal day of use I'll still have 60% of battery life. It's normally water resistant down to 6 feet for 30 minutes, flipping two switches makes it water resistant down to 15 feet for 30 minutes (and it even comes with a "drying" app that helps it to dry faster by, I think, vibrating the speakers.)
This particular phone comes with FLIR imaging, which probably isn't useful to the general population...
But a few have done what you suggest. At least slightly. The Galaxy s6 came in an active version that had like 30% more battery and better water resistance and a slightly tougher default shell.
I don't know how their sales were for the 2 models but I hope they were good enough to continue the trend
