You know you can replace the battery, right? Like, 10 minutes with some basic repair knowledge and you can have it done. I usually do a battery replacement on my iPhone ever 2 years just because it will inevitably slow down and the battery life becomes unusable.
As a former sysadmin and MDM specialist I stay(ed) loyal to Apple because MDM quickly makes you realize what a cluster android is. Some phones allow for certain lockdowns in one profile while other Android OS’ wouldn’t be able to recognize it. Knox was attempting to do something akin to iOS for MDM, but even still it was missing a ton of features.
