Comment on USB-PD is a de-facto low-power DC voltage standard, with USB-C being the universal plug. Hurray!
Smokeless7048@lemmy.world 5 months agoYea, i do think it will help, primarily with battery charging.
Right now, in order to protect the battery, the phone will request 9v, then step it down as the battery charges, and send a reduced voltage to the battery, so over time the battery might see 9v… 8.95vm 8.9v, 8.85v…
This allows the step down to happen at the charger, instead of in the phone, increasing efficiency, and reducing heat in the phone.

I think there might be an issue with the propensity of people to use random chargers. If it fits, it has to be OK right? I’m not sure one should trust the charger to step down the voltage as it charges a device. Lots of poorly designed aftermarket chargers out there and you won’t be able to make the bad ones all disappear overnight. The device needs to protect itself from the stupidity of the user.

Definitely get what you are saying, but I already trust the charger to take 120-240v AC to 5-48v DC.
Going from 9.0 to 8.85v is a much smaller regulation
