Apple typically introduces new iPhones each September, and it looks as though 2019 is shaping up to be no different.

Keeping with the pattern in 2017 and 2018, Apple is widely expected to debut three new iPhones in 2019 — and it sounds as if one of the biggest changes could be a triple-lens camera system.

Apple's iPhone launches draw massive attention from news outlets, consumers, and Wall Street, and that's bound to be the case more than ever in 2019 as the company grapples with falling iPhone sales.

Apple said in its fiscal second quarter earnings report that iPhone revenue fell yet again compared to the same quarter a year ago, dropping from $37.6 billion in the second quarter of 2018 to $31.1 billion in Q2 2019. Though other product areas are growing — such as its services business, which reached an all-time revenue high of $11.5 billion — the iPhone is still Apple's biggest moneymaker.

The next iPhone launch will likely be sandwiched in between two high-profile Android phone releases from Samsung and Google. Samsung typically unveils its stylus-wielding Galaxy Note 10 phone in late August or early September, while the Google Pixel 4 is expected to debut in October. As is usually the case, the iPhone will have significant competition heading into the holiday season.

Here's a look at what we're expecting to see in this year's iPhones, based on the reports and rumors that have surfaced so far.
