You will have to do it before you pass the event to the OS for handling. All OS event definitions are listed in the SDK headers (event.h). Use an event pre-handler routine to look for the low battery warning event before passing the event onto the OS. However, when you do encounter a low battery event, you will have to check the battery thresholds yourself as the OS post the message frequently just to check the levels. If the current battery level is below the warning threshold, you can assume a low battery warning event is about to happen. Clean up your app and let the OS handle it. A warning: Don't take too long to clean up. Once a low battery level has been detected, you cannot rely on having a specific amount of time before the unit could permanently loose power. Once that happens, you usually have 2 minutes or less to recharge or replace the batteries. The further away from completely depleted you allow the unit to shut down, the longer the memory will be retained.
