Of course, the main advantage of LTE (4G) is the speed of data transfer. Pages and other multimedia content will load much faster, and when using a smartphone in modem mode, you will get a higher level of comfort when working on a PC. But do not forget that the use of networks of LTE (4G) leads to a faster discharge of the device. This is indicated even by iOS itself when switching settings. It remains to turn off support for this wireless standard in your iPhone or iPad. About why it is needed, how to do it and on which iPhone models it is possible to read it in this article.

What Does Enable LTE Mean?

Not every iPhone has an LTE module on board. He first appeared on the iPhone 5. But another nuance lies in the fact that in each new generation of the iPhone, a more advanced LTE module is used that can provide greater bandwidth. The maximum data transfer rate, depending on the device model, is as follows:

  • iPhone 5, 5c, 5s – up to 100 Mbps;
  • iPhone SE, 6, 6 Plus – up to 150 Mbps;
  • iPhone 6s, 6s Plus – up to 300 Mbps;
  • iPhone 7, 7 Plus – up to 450 Mbps;
  • iPhone 8, 8 Plus, iPhone X, iPhone XR – up to 600 Mbps;
  • iPhone XS, XS Max – up to 1 Gbps.

Of course, these indicators can be significantly lower depending on the channel width provided by the operator, distance and congestion of base stations.
