If wifi is available, it uses less battery than 3G/4G. If wifi is not available and you leave it turned on, it will use more battery searching for a signal, so for best battery life, use wifi when available and turn it off when it isn't.I can go days on only wifi, it uses far less power than LTE>
By the way, not having the wifi toggle can't possibly be a hardware issue, since all it does is turn wifi on and off, which you can still do in the wifi menu option.
