SuperSonic charging, increased capacity: Realme wants to redefine the future of smartphone batteries

When it comes to fast charging, Realme hits it hard. The brand recently unveiled 320W charging technologycapable of recharging a 4420 mAh battery in just 4 min and 30 s. A speed that far exceeds the capabilities of other giants in the sector. For example, the OnePlus 12which stands out for its fast charging at 100 W, cannot compete with this kind of performance. Even theiPhone 16 Pro and the Galaxy S24 Ultrawith loads of 23 W and 45 W respectively, are far behind in terms of speed.

The difference in electrical standards between China and other territories, such as the United States, remains a barrier for consumers, who will have to wait some time before seeing such impressive charging speeds in their devices.

Ever bigger batteries

While fast charging is important, battery capacity is just as crucial. Realme, with its future GT8 Pro, would provide gigantic batteries of up to 8000 mAh, a capacity rarely seen in flagship smartphones. For comparison, theiPhone 16 Pro Max is satisfied with a 4685 mAh battery and the Galaxy S24+ a 5000 mAh battery. Realme is not at its first attempt, since its very recent GT7 Pro has a 6500 mAh accumulator.

Other Chinese brands, such as Oppo or Xiaomi, remain behind, but are increasing their efforts to increase the battery capacity of their devices. Oppo's Find X8 Pro, for example, offers a 5910 mAh battery, and the Xiaomi 15 Pro (only available in China to date) reaches 6100 mAh. Realme would nevertheless take a clear lead by testing different configurations for its next generation of smartphones:

• 7,000 mAh with 120W fast charging for a full charge in 42 mins
• 7,500 mAh with 100W fast charging for a full charge in 55 mins
• 8,000 mAh with 80W fast charging for a full charge in 70 mins

The emergence of silicon-carbon batteries

To support its higher capacity accumulators, Realme integrates advanced battery technologies, such as silicon-carbon batteries, which are already present in some of its models, such as the GT7 Pro who convinced us on this point. These batteries offer better longevity and increased performance compared to traditional lithium-ion batteries, and above all a significantly more compact format.

Although this process is still in development, it represents the future for smartphone durability. However, we will still have to wait before giants like Apple or Samsung fully adopt this technology. In the meantime, Realme appears poised to lead the charge when it comes to silicon battery innovations.

OnePlus, the rival that isn't really one

Faced with Realme's innovations, other manufacturers are trying to catch up. THE OnePlus 13expected in 2025, could be an interesting alternative, with its 6000 mAh battery and 100 W fast charging. However, even if it belongs to the same group as Realme, OnePlus will not compete with the 320 W charging speed, nor with the 8,000 mAh batteries planned for the GT8 Pro.
