What is iPhone 15 Bongo Haptic engine? Why was it Cancelled?


The iPhone 15 introduces an exciting new feature called Haptic Touch, which makes using your phone feel even more amazing.

Key Takeaways

  1. Improved Haptics: The iPhone 15’s Haptic Touch enhances the tactile experience with more responsive and precise vibrations.
  2. Project Bongo: Aimed to create non-moving, haptic buttons that mimic real button presses using advanced vibration technology.
  3. Cancellation Reasons: Technical challenges, supply chain issues, and battery concerns led to the exclusion of the Bongo Haptic Engine from the iPhone 15 Pro.

Evolution of Haptic Technology in iPhones


Since 2011, Apple has been making the vibrations in their iPhones better and better. It all started with the iPhone 4S when they added something called linear resonant actuators. These helped to make the phone vibrate with less noise and respond faster when you pressed something.

Then, in 2015, Apple came out with the iPhone 6s and introduced the Taptic Engine. This was a big deal and has been in every iPhone since. The Taptic Engine makes those little vibrations you feel when you interact with your phone, like when you long-press on certain parts of the screen. This is what’s behind the Haptic Touch feature.

Project Bongo: The Haptic Revolution

Project Bongo was all about changing how the volume and power buttons work on the iPhone 15. Traditional buttons actually move when you press them, but the new haptic buttons don’t. Instead of moving, they sense how hard you press and then use tiny vibrations to mimic the feeling of pressing a real button.

This is made possible by haptic engines, which create these small, responsive vibrations. So, even though the buttons don’t physically move, it still feels like they do because of the haptic feedback. It’s a clever way to make the buttons feel just as responsive without the wear and tear of moving parts.

The Bongo Haptic Engine

For the Bongo project, Apple created something called the “Bongo Haptic Engine”. This is a special type of motor called an electromagnetically driven reluctance motor. These motors are pretty high-tech and are often used in small electronic devices.

The reluctance motor allowed Apple to make vibrations that are quicker and more precise than those from traditional vibration motors. This means when you interact with your phone, you get faster responses and more detailed vibrations.

The Bongo Haptic Engine was designed to give you a better overall feel and experience when using your iPhone.

Why Was It Cancelled?

Apple decided not to include the Bongo Haptic Engine in the final design of the iPhone 15 Pro models. Instead, they opted to retain the traditional mechanical buttons for this generation. It was cancelled due to several key issues:

Technical Challenges

Integrating the new haptic feedback system proved more complex than anticipated. The Bongo Haptic Engine faced difficulties in maintaining consistent performance and reliable pressure sensitivity, making it challenging to ensure a uniform user experience.

Supply Chain Issues

The manufacturing processes for the required electromagnetically driven reluctance motors were intricate and expensive. Additionally, scaling production to meet Apple’s demands encountered delays and cost inefficiencies.

Battery Life Concerns

The advanced haptic system consumed more power than traditional buttons, potentially impacting battery life. Given Apple’s focus on battery performance, this was a significant drawback.

The iPhone 15’s Haptic Touch technology marks a big leap in how we interact with smartphones. This technology gives you a sensation similar to pressing a real button, making your experience more engaging and easy to use.

So, while you won’t see haptic buttons in the latest Pro model, the idea of using tactile feedback to enhance how we use our phones is still very much alive. It’s a step towards making our interactions with devices feel even more natural and responsive, and we can look forward to seeing more of this in the future.
