Assuming the rumors are true, the iPhone 15 Plus will offer some significant improvements over previous iPhone models. We can expect a bigger battery, a switch to USB-C and more.

Specifically, Sony’s new sensor features a stacked architecture that separates photodiodes and pixel transistors on different substrate layers. The new design approximately doubles saturation signal level and widens dynamic range.

Adaptive display brightness optimization

Adaptive display brightness optimization is a great feature that can help prevent eye strain by automatically adjusting the screen brightness to suit your environment. However, it can become a nuisance when it constantly adjusts the screen brightness without your permission. Fortunately, there are a few steps you can take to stop adaptive brightness from constantly changing your screen’s brightness.

Typically, smartphones have an ambient light sensor on the front of the device, which uses a photodiode to detect incoming light. When the light strikes the photodiode, it produces a current that is used to calculate the ambient lighting conditions. Based on this information, the device can then determine how bright to set the screen.

Android devices with Adaptive Brightness support also use on-device machine learning to figure out your preferred settings. Over time, it learns how you move the brightness slider during the day and at night, and then applies those settings automatically.

Energy efficient battery management

When you ask most iPhone owners what they want from their smartphone, the answer won’t be a thinner and lighter design, a better camera, or a super sharp display. What most will say is they want a phone that lasts longer between charges. That might finally happen this year with the iPhone 15 series if the latest rumors are true.

The rumors suggest that Apple will boost the battery capacity in all four of this year’s iPhone 15 models, including the non-Pro ones. Chinese site IT Home originally reported the new battery sizes, citing a source inside Foxconn. But the outlet later updated its report with another leaker who says the stats are false, so take them with iphone 15 plus a large grain of salt.

A dedicated power management processor will ensure the iPhone’s peak rated voltage isn’t reached during use. It will also learn charging habits and adjust the phone’s power draw accordingly. A new toggle in settings will also let you manually disable the throttling feature, which slows down a device’s processor to prevent unexpected shutdowns. It’s one way that Apple is working to avoid the kind of battery anxiety that has plagued previous iPhone generations, where underwhelming stamina leads to concerns over whether the phone will make it through a long day of work or play.

Ultra wide camera sensor advancements

Apple’s iPhone series is renowned for its camera capabilities, and this year the smartphone is expected to push the boundaries even further. According to TF Securities analyst Ming-Chi Kuo, the iPhone 15 lineup is set to feature upgraded 48-megapixel rear cameras with a stacked CMOS image sensor design that can capture more light than previous designs.

The new camera system will also reportedly come with improved image stabilization, optical zoom capabilities, and computational photography features. It’s said to offer superior low-light performance that can create images that look more like a “proper” camera than anything that’s ever been produced by a phone.

One other major improvement rumored for this year’s iPhone 15 Plus models is the inclusion of Night Mode on the wide and telephoto modules. This is a feature that’s been available on Google’s Pixel phones for some time now, and it should bring a massive upgrade in image quality when shooting in low-light conditions.

In addition to these features, the new iPhone 15 Plus is rumored to get a USB-C port in place of the Lightning connector, a change that will comply with European Union regulations. It’s also believed to replace the standard mute switch with a customizable Action button similar to what’s seen on the Apple Watch Ultra.
