While many high-end smartphone models are still stuck at around 5,000 to 6,000 mAh, the race for battery capacity is showing clear signs of acceleration, according to hindustantimes.
Products such as Poco F7 or Realme GT 7 with batteries from 7,000 to 7,550 mAh have partly opened the era of "opening the cup" of backup charging. But this number may soon be surpassed.
A source from Digital Chat Station leaked in the Chinese technology world, revealing that manufacturers are looking to 8,500 mAh batteries for smartphones in the near future.
According to the supply chain, the first devices to own this single-capacity battery could appear as early as 2026. Even testing samples for 9,000 mAh batteries have begun in the laboratory.
This step is thanks to silicon-carbon technology, which allows increasing battery capacity without significantly increasing physical size.
If traditional lithium-ion batteries only contain about 10% silicon, the new generation can increase this ratio to 25-30%, thereby optimizing energy density. In addition, the metal case design is also said to help increase storage capacity while still keeping the size compact.
This development not only helps the phone increase the battery life, but also changes user habits, from depending on backup chargers to the experience of "one-time charging for the whole day, even two days".
In the context of increasingly multi-purpose and energy-consuming smartphones, this is an inevitable direction for the industry.
The progress being seen at companies like Poco and Realme is clear. But 8,500 mAh will not only be a digital leap, but also a technological milestone, marking the time when the phone is truly battery-powered without the need to switch to a lightweight design.
