- Xiaomi has revealed that its 200W charging resolution drains battery capability at a big fee.
- Roughly two years of charging and discharging cycles will end result within the battery degrading to only over 80% capability.
Xiaomi introduced 200W wired charging final month, making for an enormous step above even ultra-fast 120W options already accessible in just a few telephones. The producer says this resolution is ready to prime up a 4,000mAh battery in simply eight minutes, however it seems that this comes at a long-term value.
Xiaomi posted a Q&A on its Weibo account right this moment, and one of many questions involved the impression of 200W charging on battery well being over time. It seems that 800 charging and discharging cycles at 200W leads to the battery degrading to “above 80%” of its authentic capability.
800 cycles corresponds to only over two years, so meaning a telephone with a 4,000mAh battery will successfully have a 3,200mAh battery (or slightly greater than this) after two years of charging through this methodology. In the meantime, a tool with a 5,000mAh battery will primarily have a ~4,000mAh battery after two years of 200W charging.
That’s roughly similar to Oppo’s 125W charging resolution introduced final 12 months. Oppo stated on the time that 800 cycles with 125W charging will drop the battery capability to 80%. The agency previously noted that its already brisk 65W resolution solely dropped the battery capability to 91%.

For what it’s value, Xiaomi claimed that the Chinese language regulatory customary for battery degradation is that 60% capability ought to be left after 400 cycles. However that looks like an absurdly low bar for smartphone battery well being when individuals are holding onto their gadgets for longer than ever. And that customary would imply a telephone with a 4,000mAh battery could be lowered to 2,400mAh capability after roughly a 12 months of charging. That’s barely sufficient for half a day, with trendy telephones providing 5G, excessive refresh fee screens, and different power-hungry options.
However, we hope smartphone corporations maintain off on implementing extra 120W to 200W charging options till they’ve discovered a method to enhance battery degradation. Till then, right this moment’s 40W, 55W, and 65W options usually ship quick speeds with out compromising battery well being to the identical extent.
