Even if your phone isn't FASTER now, it could be later.

The next iPhone's LTE speeds may be much faster. Apple plans to include a new Qualcomm LTE modem in the next iPhone that's theoretically capable of delivering speeds that are twice as fast as what the iPhone 6 is capable of, with download speeds of up to 300 Mbps, up from 150 Mbps. But while the modem makes those speeds possible, they still can't happen without the right support from carriers — and in most areas of the world, you still aren't going to get anything like those speeds. That's because those speeds rely on carriers supporting LTE Advanced, which by and large hasn't rolled out.

LTE Advanced is already available in some areas, including Korea. AT&T has also begun supporting it in some major US cities, like New York and San Francisco, but it's unclear how widespread the service is. In practice, LTE Advanced speeds are also unlikely to match the high theoretical capabilities that the standard and these chips support. Still, it's going to make your LTE service faster to some extent, and Apple's inclusion of a new chip will future-proof the next iPhone for whenever support for this standard widely rolls out. Other smartphones, including some Galaxy phones, already include this Qualcomm chip or other support for these faster speeds.

There are other possible advantages of Apple switching over to this new LTE modem. It's supposed to be more power efficient, which could result in improved battery life on the next iPhone. It's also a bit smaller. Altogether, it's possible that those will have an impact on battery life  particularly in combination with the power saving feature being built into iOS 9.
