I've been with sprint for quite a long time and considering a move to T-mobile so I can get this phone. My biggest issue is battery life. I have to plug my note 5 in constantly and this seems to be the issue with most Samsung phones. The one question I have is, can anyone here confirm that the moto z play works with band 12 on T-mobile? I can see this being of great use for me when in my office where reception is quite poor. I was browsing through some reddit forums and there seems to be discrepancy to what's listed in the specs and if it indeed works with band 12. Any help?
