TLDR:
New silicon-carbon smartphone batteries offer huge capacities in thinner phones (0:25). While many companies like Xiaomi are using them, major players like Apple, Samsung, and Google are holding back (0:55). The main reason appears to be concerns about battery swelling and longevity due to silicon expanding significantly during charging (3:09). These companies are waiting for more real-world data and improved reliability before adopting the technology on a large scale (6:44), especially given their massive production volumes (6:31) and the potentially severe consequences of battery failure (5:21). The US market’s focus on software and ecosystem lock-in also means less pressure on hardware innovation (7:11).
Oh I didn’t mean that your phone was a Samsung. Was just referencing the fact that people’s brand recognition was forever altered by an issue that objectively was not a major issue in the grand scheme. Companies don’t want to risk that type of thing again.
