Just more of an observation, I saw that my new Nextbit Robin - when plugged in to my HP Envy laptop USB-C charger shows the message “Charging Slowly” which I had never seen in 7 years of Android use, I guess it’s a message that only displays on certain android builds, because I have always used Samsung Galaxy Notes and Huwawei devices and I only ever see - Charging x minutes remaining - or Fast Charging x minutes remaining.
I have several Qualcom fast chargers but I was travelling so my laptop was the only USB C charger around,
Just thought it was interesting as I have only just migrated over to using a USB C only laptop and USB C smartphone…
It seems like the USB C smart devices are quite fussy if you don’t use their original oem manufacturer cable and charger,
what are your experiences?
Android Charging Slowly message on sleep mode/hibernation mode
With my Pixel I have found the charging slowly message appears when it is receiving less than 1500mA. Or if it is charging the last 15-20%.
Charging rapidly normally appears at around 2000mA.
Certain cables can only carry a max of 1500mA even if the charger/port can output more.
If you are using a cable that can support more than 1500mA then have a look at your PC. It may be restricting the power out put on ports when it is not charging itself.
On Android newer versions you can swipe down and change from using USB for charging or data transfer. You may have a default of using for data so it runs in a lower power mode.
I believe in USB-C standards the higher power modes are only possible if using the data pins for power.
From what I have found out, this is how QuickCharge works.
USB C Power Delivery standard, as set out by http://www.usb.org/ states that USB C cables should have 4 Vbus pins (power).
Table from "USB Type-S Specification Release 1.2.pdf from http://www.usb.org/developers/docs/
Quick charge is not USB-PD.
Correct, if you are referring to Qualcom Quick Charge.
Charging “rapidly” however is supported by USB-PD.
