iPhone 15 Plus in Photos: Gets the Dynamic Island makeover
Apple update
1/5 The iPhone 15 Plus gets the same 6.7-inch Super Retina XDR display as its predecessor, although the peak brightness has now been bumped up to a staggering 2000 nits, which is super useful especially outdoors. However, it still sticks with the 60Hz refresh rate. Therefore, the lack of ProMotion is a bummer. (Shaurya Tomer/HT Tech)

2/5 Finally! Apple has got rid of the notch and brought the Dynamic Island, which debuted with the iPhone 14 Pro models, to the iPhone 15 Plus. It is a nifty little feature that is useful when you’re streaming music, navigating routes, ordering food, or doing all of those things simultaneously. (Shaurya Tomer/HT Tech)

3/5 The shiny glass at the back is no more, and the iPhone 15 Plus now gets a new soft, matte finish which is less of a fingerprint magnet. While the smartphone’s design is almost identical to its predecessor, it now gets slightly rounded edges which makes it far more comfortable to hold for longer periods. And yes, the iconic mute switch is still here on the iPhone 15 Plus. (Shaurya Tomer/HT Tech)

4/5 Lightning is officially dead! After years of resisting peer pressure, Apple has finally adopted USB Type-C, complying with the EU’s new regulations. But we’re not complaining. Apple has provided a nice, braided cable with the iPhone 15 Plus, although the charging speed is still limited to 20W. (Shaurya Tomer/HT Tech)

5/5 One of the main changes this year is the camera system. After a couple of generations featuring the same 12MP camera, Apple has finally brought the 48MP camera to the iPhone 15 Plus, and the difference is instantly noticeable, with well-detailed images. With the new Smart HDR 5, photos are now well-balanced with good exposure. Stay tuned for some amazing snapshots in our full review which comes out soon! (Shaurya Tomer/HT Tech)

iOS update: Apple's newest iPhone 15 series was unveiled to the public with huge excitement. However, some users have reported heating issues with the iPhone 15 models. While this was initially attributed to the new A17 Pro chip, Apple quickly dismissed these claims, stating that it was due to some third-party apps as well as a software issue that would soon be fixed. Now, the Cupertino-based tech giant has rolled out an update that not only promises to fix the heating issues but also brings a solution for a critical security flaw in the previous versions of iOS that has already been actively exploited.

iOS 17.0.3 update: Details

While iOS 17.0.3 does not add any new features to the iPhone, it brings a fix for a critical security flaw.

According to Apple's security releases page, the update fixes an issue with the Kernel, termed CVE-2023-42824.
