Requirements
What has to be true
- USB-C PPS-compatible power adapter at the documented power class.
- Suitable USB-C cable.
- Normal thermal/battery conditions.
Verify it yourself
Use this test sequence
Change one variable at a time so you know which requirement made the difference.
- 1
Read the adapter's output profiles, not only the headline wattage.
- 2
Test with a known PPS charger and cable.
- 3
Compare from a similar low starting battery percentage; charging tapers as state of charge rises.
Limits
What this answer does not prove
- Charge time varies with temperature, battery age, active use and starting state.
- The browser cannot directly read negotiated USB PD/PPS power on the phone.
