Xiaomi head of communications Daniel Desjarlais told The Verge that you can expect 80% battery capacity after 800 charging cycles at this speed (equivalent to roughly two years).
Now, that 20% might sound like ‘oh wow, I’m losing 20%,’ but that’s quite standard across basically all charging tech. 800 cycles, for most people, it’s going to be two years roughly. So that’s quite solid.
Desjarlais also told the outlet that there were “relatively minute differences” to battery degradation when using a slower charger versus a 120W adapter. But he noted that the ideal situation would be for consumers to use a slower charger overnight.
How does this compare though?
This isn’t the first time we’ve seen Xiaomi tout these figures, as it revealed 200W wired charging earlier this year that also promised 80% capacity retained after 800 charging cycles. Nevertheless, 20% battery degradation seems about on par for 100W+ speeds, as Oppo previously stated that its 125W solution results in the same drop after 800 cycles too.
