Xiaomi communications chief Daniel Desjarlais said The edge that you can expect 80% battery capacity after 800 charging cycles at this speed (corresponds to about two years).
Well, that 20% may sound like “oh wow, I’m losing 20%” but that’s pretty much pretty standard across all charging technologies. 800 cycles, for most people it will take about two years. So that’s pretty solid.
Desjarlais also told the outlet that there are “relatively tiny differences” in battery degradation when using a slower charger versus a 120W adapter. However, he found that the ideal situation for consumers would be to use a slower charger overnight.
But how does that compare?
This isn’t the first time Xiaomi has touted these numbers, as a wired 200W charge was unveiled earlier this year, which also promised 80 percent capacity after 800 charge cycles. That said, the 20% battery degradation appears to be roughly the same for speeds greater than 100W, as Oppo previously said that its 125W solution produces the same drop even after 800 cycles.
