Moto Mods vs. Jeans Pockets?

[AC Question]

I am considering purchasing the Motorola Moto Z Droid (either the regular or the "Force" version), and I am interested in the answer to this question: while I avoid buying tight fitting jeans, I was wondering if I still may have a problem with Moto Mods coming off inadvertantly, while I am either putting the Moto Z Droid (with a wireless charging capable battery pack) in my jeans' pocket, and/or removing it from my jeans' pocket. Have any current owners ran into that as a problem, or not? I have briefly played with a store's demo Moto Z Droid and Moto Mods, so how do know that they fit together pretty firmly, but maybe not firmly enough to not cause problems with regards to frequent storage in and removal from jeans' pockets? Thanks in advance!
