Over the years, we’ve seen smartphone companies create faster and more powerful charging for smartphones. While the actual batteries remain the same, the faster charging will allow them to recharge faster, so while we may not be seeing phones that last a week on a single charge, the upside is that we now spend less time waiting for them to be recharged.
That being said, at MWC 2023, Xiaomi has taken the wraps off its latest charging technology that uses 300W of power to charge a smartphone. Based on its demo, it seems that by using 300W of power, it can fully recharge a phone with a 4,100mAh battery in just 5 minutes, which is pretty crazy if you think about it.
In this particular instance though, Xiaomi used a Redmin Note 12 Pro+ which apparently uses a new type of battery. This new battery uses carbon materials in place of graphite which reduces the electrodes’ thickness by about 35%. Combined with a new electrolyte formula, this lithium-ion battery packs higher power density with a faster charge and discharge rate, reducing the amount of heat produced.
It’s actually pretty cool to see how fast a phone can charge with that much power flowing into it, but the downside here is that Xiaomi did not mention whether or not they plan on mass producing this new 300W charging tech, or if it is simply a demo of what they’ve managed to achieve so far.
To be fair, a lot of the current charging solutions are already pretty fast compared to 5-6 years ago, but the idea of having to only spend less than 10 minutes charging our phones a day does sound rather appealing.
