The energy profiler (Figure 82-19) provides a realtime analysis of the energy used by the currently running app categorized in terms of CPU, networking and location tracking activity.
The Energy profiler includes an event timeline (A) and a graph indicating the current energy usage (B). The graph is colored based on the key (C) which also indicates the current energy usage levels of the three categories. Selecting a section of the graph will list any system processes that are contributing to excessive energy use such as alarms and jobs, location requests or wake locks.
