So ive had my s4 for nearly 2 weeks now and noticed my signal quality (not data or wifi) is pretty much always 1-2 bars strength and more commonly zero bars. I live in the heart of Phoenix Arizona and my carrier informed me im in an LTE area of coverage. However, due to the poor signal quality everywhere I go in Phoenix, my carrier had me switch my network mode from lte/gsm/wcdma to just gsm/wcdma. I now receive a much better signal quality and I am hoping this helps battery life. But my question is, what will I be missing out on by switching off of the network mode that contains lte?
