Barely two weeks ago, we spoke about Xiaomi’s super impressive 200W HyperCharge technology that managed to fully charge a phone with a 4,000mAh battery in just 8 minutes. Now, Xiaomi has released a Q&A about their new fastcharge tech on Weibo, in which they also disclose just how much it’ll impact battery life.
According to Xiaomi, they had tested the 200W HyperCharge for 800 cycles on a device, which is roughly two years of everyday use. They found that battery life was reduced to ‘above 80%’. While that wouldn’t seem like it’s very good, it’s perhaps worth noting that China’s national regulations dictate that battery life needs to be at least 60% capacity at full charge after 400 cycles, so Xiaomi does indeed pass the mark in that regard.
If you do the math, that means that for the 4,000mAh battery Xiaomi showed off being charged in the original HyperCharge video, two years of use would wear the battery to just a max capacity of 3,200mAh. Similarly, if you have a 5,000mAh battery, two years of HyperCharge use could see it drop to just a 4,000mAh maximum capacity.
From Xiaomi’s Q&A on Weibo 
While Xiaomi did seem to position HyperCharge as performing better than what China’s regulations state, it should be noted that 60% of maximum capacity after just 400 cycles (roughly a year of use) seems like a pretty low bar to hit in the first place. And with smartphones these days coming with more and more features that require a decent amount of power – high refresh rate screens, 5G support, reverse charging – having just 60% of your battery after a year or even just 80% after two might not be enough juice for most users.
A 200W charger on a mobile phone might also seem pretty unsafe, but Xiaomi did address that in their Q&A too, saying that they’ll be conducting tests on HyperCharge to ensure it passes standards for stuff like corrosion resistance, spark tests and the like. They also addressed concerns of overheating, claiming that they’ve put in place heat dissipation solutions both on a hardware and software level. Even the battery itself works to dissipate heat using a graphite sheet on the back of the battery. If you want more details about Xiaomi’s HyperCharge, you can visit it’s Q&A here.
So would you pick up Xiaomi’s 200W charging solution if given the chance, despite battery degradation concerns? Or are the current fast charge options more than enough for you? Let us know what you think below!
