I have come to the conclusion that something is seriously wrong with 4G in Manhattan. On a recent train ride out to long island I had perfect LTE and barely used my battery.
Meanwhile I am lucky if I can get a minute of data before losing the connection and switching rapidly back and forth between no data/3G/4G.
This is truly pathetic Verizon. The same hardware two years ago was flawless in NYC. I am probably going to go month to month and buy my phone at full price just to avoid the risk of being tied to this nonsense.
