when Show charging information(Settings > Display > Show charging information)option is activated on new Android R OS software version, the battery level and estimated time that had been exposed continuously to the Lock screen while charging appear only for 5 minutes after fully charging. This is a new concept to prevent battery consumption due to unnecessary screen turn on after full charging.
If you turn on the Show always of Always On Display(Settings > Lock screen > Always On Display) feature, charging information is displayed along with the clock information even after being fully charged as before
Always on screen is already on. Actually it not always doesn't show the time remaining for charging. Sometimes it does, like now it showed. But maybe tomorrow it will not be shown again. It has been happening for about nearly a month
The screen is displayed with charging information along with the clock information even after the battery has been fully charged by switching on the Show Always On Display feature (Settings > Lock screen > Always On Display) feature.
