It's also disappointing that while Pixel 3 supports USB-PD, which is forward looking, it has no support for older protocols, even conventional 2.4A USB charging. I tried charging one with my car USB port and it the charging rate was lower than the power consumption, so it died after a few hours of navigation.
There are tons of conventional chargers out in the world (card, hotels and airports, power banks, etc.) and it's stupid to deprecate them, especially given that the Snapdragon inside actually supports those.
- dstaley 8y agoAs far as I can tell, there's no such thing as "conventional 2.4A USB charging". The USB 2 spec limits power output to 5v, 900 mA. USB 3 has the Battery Charging Specification that allows up to 1.5 A. I think you might be thinking of Qualcomm Quick Charge?
- aidenn0 8y agoUSB 2.0 Battery Charging Spec 1.2 goes up to 5A.
- ianburrell 8y agoThe USB Battery Charging spec is separate from USB3. The 1.5A is the minimum available current for charging port; the max is 5A. But the limit for legacy USB cables is 2.4A.
- bitwize 8y agoYou really don't want to go plugging your phone into a random USB port, irrespective of whether it's compatible with the charger or not.
- ianburrell 8y agoIt is pretty unbelievable that it doesn't and I haven't seen any other reports. Lots of car USB ports only provide the base 500 mA. Did you try any other USB chargers? Did you use Ampere app to see the current?
