Some basic information before asking for help:
Model Name: ROG Phone 5
Firmware Version: RKQ1.201022.002.WW_Phone-18.0840.2106.86
Rooted or not: Not rooted
I set the scheduled charging time from 11:30 pm to 7:30 am. Furthermore I used the Ultra Steady Charging. But my phone got fully charged after 1 hour and 33 minutes.
Shouldn't this feature be charging my phone to full by the end time of scheduled charging viz. 7:30 am ?
