The iPhone 11 could finally introduce upgraded Bluetooth capabilities23
Listen to audio through two Bluetooth devices simultaneously
Although the latest iPhones do support multiroom audio to AirPlay 2 speakers, Apple’s software current limits audio through regular Bluetooth devices to just one at a time. But starting with the iPhone 11 lineup, Apple could finally adopt Dual Audio which, as its name suggests, allows audio to be played through two Bluetooth devices simultaneously. The feature is already present on Samsung's Galaxy S10 and in practice means that you could play audio through two sets of AirPods, two speakers, or any other combination of Bluetooth devices.
Aside from software support, the only requirement for this feature to work is the presence of a Bluetooth 5.0 chip. As a result, the iOS 13 update that Apple will be announcing next week may also introduce Dual Audio support for devices dating back to the iPhone 8 and iPhone 8 Plus, both of which were the first iPhones to include Bluetooth 5.0 chips.
Reportedly, this will be paired with bigger batteries inside all three devices. Specifically, the iPhone 11 Max is rumored to include a capacity of between 3,491mAh and 3,650mAh, while the regular iPhone 11 should boast a battery capacity of between 3189mAh and 3,322mAh. The iPhone 11R, on the other hand, may include a 3,089mAh cell. Another rumor suggests Apple’s next flagships will ship with 18W USB-C fast chargers in the box, rather than the 5W equivalent currently used.
The iPhone 11 series will reportedly bring big camera upgrades
Regarding the iPhone 11R, this particular model isn’t set to include the super-wide-angle camera due to its lower price point. However, previous renders have suggested the 12-megapixel telephoto camera will indeed make an appearance.
Completing the camera setup on all devices will apparently be an upgraded selfie snapper that boasts a 12-megapixel resolution – existing iPhones sport 7-megapixel sensors – although it’s unclear at this point if Apple has any new software features planned for this camera.
