On the outside, the iPhone 7 and the iPhone 7 Plus look a lot like the iPhone 6s and the iPhone 6s Plus. The dimensions, aside from weight, are identical. The iPhone 7 measures in at 138.3mm tall, 67.1mm wide, and 7.1mm thick, while the iPhone 7 Plus is 158.2mm tall, 77.9mm wide, and 7.3mm thick.
At 138 grams and 188 grams for the iPhone 7 and iPhone 7 Plus, respectively, the two devices are slightly lighter than previous-generation iPhones
Design wise, there are few visual differences between the iPhone 6s and the iPhone 7, aside from relocated antenna bands that no longer span across the back of the iPhone and larger protruding cameras, a feature that is especially noticeable on the larger iPhone 7 Plus with a dual-camera setup.
Power Management for Depleted Batteries
In devices that have degraded lithium-ion batteries, Apple has introduced power management features that can slow down the iPhone during times of peak power draw to prevent unexpected shutdowns.
Apple first introduced the power management features in iOS 10.2.1, but the issue received additional attention at the end of 2017 after it became clear that power management involved slowing down iPhones with batteries that are running at a sub-optimal level.
Several lawsuits have been filed against Apple accusing the company of deliberately slowing devices to encourage upgrades, which Apple says it does not do. Power management features are designed to extend the life of the iPhone rather than shorten it.
Following significant backlash over the issue, Apple announced a $29 battery replacement program, allows customers who have an iPhone 6 or later to replace their batteries for $29 regardless of battery health.
Apple is using a display in the iPhone 7 that’s 25 percent brighter than the display in the iPhone 6s, so it’s going to look brighter and clearer outdoors, especially in full sunlight. The display is also using a cinema-standard wide color gamut and end-to-end color management, for more vivid, saturated colors.
3D Touch continues to be an integral part of the display, built into one of the display layers. 3D Touch is an expanded multi-touch feature that allows the iPhone to measure different levels of pressure in addition to taps, swipes, and pinches.
3D Touch is used across iOS 9 and iOS 10 to enable shortcut gestures called a “Peek” and a “Pop” both at the home screen and in iOS apps. A light press enables a Peek, while a deeper press enables a Pop, and there are unique swipe gestures to open up menus and take actions when using Peeks.
Redesigned Home Button
The Home button on the iPhone 7 looks like the iPhone 6s Home button, but it’s no longer a physical button. Apple calls it a “solid state” button, and when you press on it, you get haptic feedback from the Taptic Engine to mimic a button press, similar to the trackpad on the latest MacBooks.
Instead of feeling the sensation of pressing down on an actual button, when you use the Home button on the iPhone 7, you’ll feel haptic vibrations in response to let you know that actions like unlocking the iPhone’s screen or making a payment with Apple Pay have been successful.
When setting up the iPhone 7, you can choose the level of haptic feedback you want, ranging from light to powerful, with a setting in the middle available. It should be noted that the iPhone 7 Home button is capacitive, requiring skin contact or the right kind of capacitive gloves to press.It otherwise won’t register touch, unlike the physical home buttons of earlier devices.
The Home button in the iPhone 7 is powered by a redesigned and updated Taptic Engine, a piece of hardware that was first introduced in the iPhone 6s. According to Apple, the Taptic Engine is more responsive and works with a wider range of frequencies.
It is used throughout the iPhone 7 system for everything from the Home button to notification vibrations, and for the first time, it can be programmed by third-party applications for new feelings and experiences that were not previously available.
The Touch ID fingerprint sensor that replaces passwords and offers additional security for things like Apple Pay payments is still located on the Home button, despite the Home button’s redesign.
Second-generation Touch ID technology is built into the iPhone 7 and the Touch ID fingerprint sensor is as quick
A10 Fusion Processor
Apple improves the processor in each iteration of the iPhone, and in the iPhone 7, some impressive features have been included for the best chip performance in an iOS device yet. The A10 Fusion has a four-core CPU (the first in an iOS device) that combines power and efficiency in a unique way. It is “incredibly thin” and was made on TSMC’s 16 nm FinFET+ process.
- Best-in-class performance
- Good battery life
- Improved cameras
- iOS 10, timely updates
Low light camera performance not best in class
