I dont quite follow, there is no case that is actually waterproof? Ive never used my phone while swimming or playing in the rain and i dont recommend anyone doing that, ive not had a problem with moisture even in 90%humid with me sweating for 12 hours straight... Just under 7/8 of an inch thick and as to the battery being exposed.... Not sure what you mean, this is the most protective case made period, including otterbox, original kraken, liquipel, z shield, or any other things you've seen. The kraken 2 got horrible reviews btw, doesnt snap together properly and wears out quick, kraken original or electra is what you want.
And the creeper under the car is a non issue you'd have to litterally be upside down and getting shaken for this to fall out
