About a year ago, I updated my Moto Z to version 7 and my battery life went from about 1 week to about one day. With each update, it got worse and worse. However, the latest version 8 update caused extreme battery drain and now my Moto Z battery only lasts about 45 minutes before shutting off at 50-60%. Is there a resolution to this issue yet? This was a great phone for the first few months I had it, but these updates have been killing the functionality. I have been using Droid phones since 2012, but this will absolutely be there last Motorola product I ever buy if there is no prompt resolution. The complete lack of support has been appalling and I almost think my old flip phone from 2008 is more functional than this expensive paperweight.
