The race for bigger capacity batteries is only just getting started. 2025, so far, has been the year of thin smartphones and mammoth battery capacities. We have already reached the 8,000mAh mark and now, a new report indicates a Redmi phone is on its way to go beyond that even.
Popular tipster Digital Chat Station (DCS) claims that the next mid-range offering from Xiaomi sub-brand Redmi will reportedly feature a battery capacity between the 8,500mAh and 9,000mAh mark.
Xiaomi is looking to achieve the said capacity by developing its own battery tech. The solution will build upon the silicon carbon foundation itself with the goal of improving the charging cycle lifespan.
This has been one of the key issues that smartphones with high-capacity silicon-carbon batteries are facing currently. Although smartphones are packing 7,000mAh and 8,000mAh cells, they are unable to hold their charge for long. This is largely because silicon has lower electrical conductivity than graphite. This reduces the battery's ability to hold a charge for long and can lead to a quick discharge rate.
Another issue with silicon carbon batteries is in terms of longevity. Silicon swelling is a very real issue and can affect any big capacity smartphone in the long run. On top of that, software optimisation and power-hungry mobile processors play a huge role in a downgraded battery life experience.
Hence, while silicon-carbon batteries offer higher energy density on paper, real-world performance largely varies and rarely matches expectations. So, it is good to know that Xiaomi is working to most likely tackle these issues while still making sure an 8,500+mAh battery makes its way to the next device.
Apart from this, DCS claims that the work-in-progress smartphone will also be thin at 8.5mm. If true, this will be really impressive because the recently launched iQOO Z10 Turbo+ features an 8,000mAh cell within an 8.16mm body.
With that said, at the time of writing, the name of the upcoming Redmi smartphone is not yet known. However, as more details surface in the coming days, we will most likely be able to put a name to the mystery Redmi phone.
