While the battery is being charged and the system is in suspend-to-RAM,
we may need to monitor the battery health by looking at the ambient or
battery temperature. We can accomplish this by waking up the system
periodically. However, such a method wakes up devices unncessary for
periodically. However, such a method wakes up devices unnecessarily for
monitoring the battery health and tasks, and user processes that are
supposed to be kept suspended. That, in turn, incurs unnecessary power
consumption and slow down charging process. Or even, such peak power
