Answer

Explanation:

Step1: Analyze battery - life increase

When the phone is plugged in, the battery life either increases or stays at 100%. We look for points where the battery - life graph has a positive slope or is at a horizontal line at 100%.

Step2: Check time points

At 9 hours, the battery life starts to increase from a low value. At 11 hours, the battery life is at 100% and remains constant for a while. At 19 hours, the battery life starts to increase again.

Answer:

9 hours, 11 hours, 19 hours
