White Paper: realme Bets Big on Smartphone Fast Charging, Leads Market with 240W


Smartphones have become the primary mode for consumers to remain connected to everything important to them in their lives. As a result, smartphone usage is increasing continuously, with nearly half of all smartphone users spending at least five hours a day on their devices. Consumers use their smartphones to keep in touch with friends and family, browse the internet, stream content, and play games. In addition, they do work, pay for things, take photos and make videos. All these tasks consume power and there is nothing worse than running out of battery charge before the day’s end.

But that’s not all, constant improvements in smartphone technology are increasing the phone’s demand for power. Smartphones are now almost all based on fifth-generation cellular technology. 5G provides faster data speeds and more network capacity, but it consumes more power than 4G.  In addition, advances in cameras, displays and processors all demand more power. More and more smartphones now have multiple cameras with performance among the best rivalling D-SLR cameras in some situations. Displays are increasingly based on new processes that deliver larger, brighter and faster-responding displays that are great for gaming. And the chipsets at the heart of smartphones are becoming faster and more powerful with the ability to run artificial intelligence algorithms that provide multiple improvements in everything from optimizing camera performance to simultaneous language translation.

Perhaps the most obvious way is to improve battery life and increase the capacity of the battery. And this is exactly what we have seen; the global average smartphone battery capacity increased by 50% from 3000 mAh in 2018 to 4500 mAh in 2022. However, to keep smartphone designs attractive, there is a limit to how big batteries can become.

Now fast charging has become almost a default feature in many smartphones and what we are now seeing is an acceleration in the charging power. In simple language, higher power is the primary factor enabling faster charging. By examining the sales penetration across different regions and price ranges, this whitepaper delves into the emerging trends in fast charging within the smartphone industry.
