One of the everyday concerns we all have is battery life. All these years later, while battery technology has improved, the demands on battery life are higher than ever: huge displays with higher refresh rates, 5G modems, higher-powered devices, larger silicon, more cameras, and so on. No matter how many battery breakthroughs there are, most come with trade-offs around long-term battery life, how much charge can be stored, and so on. Speaking of: there’s been a breakthrough in battery technology thanks to sugar : Australian scientists have found that by using a glucose-based additive on the positive electrode (cathode) they have managed to stabilize lithium-sulfur battery technology. The iPhone will probably stick with 18W wired charging as in the iPhone 12, though it could get a speed boost.
