For many years, smartphones have used lithium-ion batteries, which require daily charging sessions and force frequent travellers to keep a powerbank in their handbags. Now, the situation is changing with the adoption of silicon-carbon batteries, which are a major incremental advancement in cellphone batteries. Companies like OnePlus, Motorola, iQOO and more are using this new battery technology in some phones, without making phones bulky.
