The iPhone 16’s Hidden Battery Upgrade: A Game-Changer
Introduction
The new iPhone 16 and 16 Plus may look similar to their predecessors, but they hide a revolutionary feature that could change the way we think about smartphone batteries.
Major Internal Changes
In a recent teardown by iFixit, several internal modifications were discovered:
- L-shaped logic board
- Removal of one mmWave 5G antenna
These changes are primarily due to the new battery design, which features larger batteries encased in hard steel instead of soft pouches.
The Secret Adhesive
The most astonishing discovery lies beneath the battery. iFixit found that the batteries are secured with a smart adhesive that debonds when an electrical current is applied. This innovation eliminates the need for brittle adhesive strips and makes battery replacement much easier.
How It Works:
- Attach an alligator clip to the silver tab on the battery.
- Connect another clip to the grounding screw by the USB-C port.
- Apply a 9V current, and within a minute, the battery releases from its case.
When replacing with a new battery, this substrate layer will rebond seamlessly.

Conclusion
This hidden feature not only simplifies repairs but also sets a new standard for smartphone design. With such innovations, Apple continues to push boundaries in technology and user experience.
