Answer

Explanation:

Step1: Analyze battery - life graph

When the phone is charging, the battery - life percentage either increases or stays at 100%.

Step2: Identify increasing or constant sections

We look for parts of the graph where the battery - life percentage is rising or is at 100%.

Step3: Match with time values

From the graph, we can see that at 9 hours, 11 hours, and 19 hours, the battery - life is either increasing or at 100%.

Answer:

9 hours, 11 hours, 19 hours
