Like most iPhone users, I might have a battery life problem. It's not that I run out of battery when I least expect it. I worry about battery life without having a good reason to. It's probably related to past battery trauma, instances where I ran out of juice and don't want to repeat. I want better battery life from the iPhone, the Apple Watch, and the MacBook. That's probably understandable. The smartphone is especially important in our lives, the main computer for most people.
ETNews also says that Apple is looking at carbon nanotubes as conductive materials. These can improve performance compared to the current solution. Finally, Apple is looking to replace graphite in the anode with silicon. This can increase battery capacity and reduce charging times. Apple reportedly has a solution for the silicon problem. The material tends to expand in volume during the charging and discharging process. Apple has been working on its battery tech since 2018.
