I've done the 5s battery replacement and would say that it is not "easy" (I work with electronics HW everyday). It is a pain in the ass and requires tools, a serious chunk of time, a clear desk and the right attitude/patience. This is something that can become routine for practiced folks, or for people that are motivated to try the challenge, but there's a lot of opportunity for mishaps. In fact one way that many people get new phones is when Genius Bars screw-up the battery replacement-- so even pro's can't get it right 100% of the time.
