Leaks suggest the Nothing Phone 3a will house a 5,000mAh battery, an upgrade from previous models, ensuring all-day usage. Charging speeds are rumored to improve as well, with support for 45W wired fast charging and 15W wireless charging. If true, this would mark the first time Nothing’s budget-friendly lineup includes wireless charging, adding to its premium feel. AI-driven battery optimizations could further enhance efficiency, adapting charging speeds based on usage patterns. With a larger battery and faster charging, the Phone 3a could easily last a full day on a single charge.
