Apple is expected to launch 3 new iPhones this year - here's everything we know so far

Apple's next iPhone could have three cameras on its back, echoing moves recently made by firms such as Samsung and Huawei.

The new high-end iPhone, likely the successor to the iPhone XS Max, would be the only one in Apple's new lineup to feature this triple-camera system, according to The Wall Street Journal and Bloomberg. Apple's other less expensive iPhones might eventually get this triple camera, however, Bloomberg reports. Last year, Taiwanese outlet Economic News Daily also reported that Apple is working on a new iPhone with three cameras.

The addition of a third camera could enable the iPhone to capture a larger field of view and better zoom shots, Bloomberg notes.

Apple's 2019 iPhones will be the same size as its current iPhones, according to a note from TF International Securities analyst Ming-Chi Kuo as reported by 9to5Mac. Kuo is generally considered to be a reliable source for Apple product news considering some of his predictions have proven correct in the past.

It's also possible that Apple will use organic light emitting diode (OLED) screens for all three of its 2019 iPhones, including the least expensive model. That would be a departure from the company's current lineup, as the entry level iPhone XR is the only device in the newest iPhone family to use a liquid crystal display (LCD). OLED screens typically offer deeper blacks and bolder colors, resulting in better contrast than LCD displays.

South Korean news source Electronic Times reported that Apple may use OLED screens for all three of its 2019 new iPhones in May, but Kuo predicts that one model will still have an LCD display.

Apple's facial-recognition system may be getting an update this year. The company plans to implement an upgraded Face ID system on its new iPhones that would "lower the impacts of invisible lights" in the user's environment to improve the experience, according to a note from Kuo which MacRumors reported. A report from Bloomberg also notes that Apple plans to improve its Face ID feature.

Apple is expected to bring a more sophisticated 3-D camera to its 2020 iPhones that would allow for better augmented reality performance, but this technology might show up on a new iPad first, as both Kuo and Bloomberg report.

Apple's new iPhones will reportedly come with the same 5W charging brick Apple has been bundling with its phones for years according to MacOtakara, even as fast-charging bricks have become an increasingly common standard for Android phones. That means iPhone owners looking to charge their phones more quickly will still have to purchase an 18W charger separately.

All three of Apple's new iPhones will include support for bilateral charging, which means they will be capable of charging other devices, according to a prediction from Kuo reported by 9to5Mac.

Samsung's new Galaxy S10 already supports this feature, which makes it possible to charge devices compatible with the Qi standard like its Galaxy Watch Active and Galaxy Buds by resting them on the back of the device.

Apple typically requires its iPhones to be charged with its own proprietary charger, but there's a chance that could change this year. The company has tested some versions of its 2019 iPhone that would charge via USB-C rather than Apple's Lightning port, according to Bloomberg. That conflicts with Kuo's prediction that Apple's new iPhones would once again only be compatible with its Lightning charger.

Don't expect this year's iPhones to look much different than the iPhone XR, iPhone XS, and iPhone XS Max.

Apple's new iPhones will "look similar to the current models," Bloomberg reports, as Apple is reportedly planning larger changes in 2020 to allow for 5G support. Kuo, however, indicates the new models could feature a frosted glass casing and will still retain the same "notch" near the top of the display.

This year's iPhones will run on a new processor, as is typically the case with Apple's new iPhones, which Bloomberg reported. Kuo also mentions a few other internal updates in his note as MacRumors points out, which include upgraded batteries and an Ultra Wide Band component that would allow for better indoor positioning and navigation. Apple's iPhone XR follow-up is expected to include 4GB of RAM rather than the 3GB the current model has.
