With the iPhone 17 and iPhone Air, features like the new selfie camera and Ceramic Shield 2 are getting all the hype. However, the new smartphones come with numerous other features. Some of these are rarely discussed–TECHBOOK highlights the best ones.
Faster Charging with the iPhone Air
For the Air, Apple has released a new MagSafe battery that extends video playback battery life to up to 40 hours. Hidden in the product description is one of the best new features enabled by the battery pack.
When the battery is connected and a 20-watt charger is used simultaneously, users benefit from significantly shorter charging times. While the battery alone charges at a maximum of 12 watts, using it in parallel with a power adapter allows for better energy distribution. So, if you need a quick battery boost, you save valuable time as the iPhone is ready for use faster.
Apple Solves the Screen Flickering Problem
For the first time, Apple allows users to disable pulse-width modulation (PWM) on iPhones. This is a breakthrough for people with sensitive eyes who have had issues with previous iPhone models and other smartphones. PWM is used to regulate display brightness but can cause headaches or eye strain in sensitive users.
The new option allows users to turn off the feature in settings, so the display operates at a consistent brightness. Although this may slightly increase energy consumption, affected users benefit significantly.

New Charging Standard with Boost Function on the iPhone 17
For the first time, the iPhone 17, iPhone 17 Pro, and 17 Pro Max support the new Power Delivery (PD) 3.2 charging standard. With a compatible charger, the devices can charge the battery to 50 percent in just 20 minutes.
So far, only Apple offers a charger with Power Delivery 3.2, reaching up to 60 watts of peak power dynamically. However, the “Dynamic Power” adapter is currently only available in select countries–not in Germany. Users there will have to wait until compatible PD-3.2 devices become available.
Improved Memory Security
In recent years, memory errors on the iPhone have repeatedly led to security vulnerabilities. With the new Memory Integrity Enforcement (MIE) feature, Apple aims to significantly improve system security. This protection technology monitors access to memory areas and actively prevents tampering. It is particularly effective against attacks that exploit weaknesses in the memory.
The feature runs largely in the background and requires no user intervention. For users, this means more security without sacrificing convenience. Especially in times of increasing cyberattacks and targeted exploits, this additional layer of protection is an important step in enhancing iPhone security.
