Welcome to the “Big Battery Era” of smartphones, where battery life is finally being prioritized by manufacturers. Gone are the days when users had to charge their devices multiple times a day just to make it through. The new goal for smartphones is to provide batteries that can last for days, allowing users to skip charges without losing functionality.
Between 2025 and 2026, we expect to see a significant shift in smartphone battery capacities. After hovering around the 5000 mAh mark for years, the industry is moving towards batteries in the 7000-8000 mAh range. Recently, Honor announced its new Power line, which includes a model rumored to feature an impressive 8000 mAh battery.
According to the well-known leaker Digital Chat Station, most flagship Android phones by the end of this year will sport batteries of at least 7000 mAh, with some even reaching 7500 mAh. A notable example is the Red Magic 10 Pro, which already comes with a 7050 mAh battery. This leap in battery size is complemented by advancements in charging technology.
The new battery systems are expected to support 100W wired charging and 50W-80W wireless charging. This is crucial because larger batteries can take longer to charge, and faster charging solutions will alleviate that wait time. Additionally, major brands like Samsung are exploring ways to increase battery capacity by redesigning elements like the S Pen storage in the Galaxy S26 Ultra.
It’s part of a larger trend where manufacturers are transitioning from traditional lithium-ion to silicon-carbon batteries, which can store more energy while maintaining the same size. This shift enables devices to feature larger batteries without making them bulkier or heavier. As we step into this exciting future, smartphone users can look forward to more powerful devices that keep up with their needs.
