For me, 60 seconds is about the threshold where I start to wonder whether you are doing more harm than good with AlarmManager. However, that's just a gut feel for me -- I have not tried running any tests to confirm whether constantly starting and stopping things will use more power than leaving them run all the time. > To make this a more practical question: I need to do something 30 > minutes before an astronomical event. Hopefully the "astronomical event" doesn't involve an impact crater on Earth. :-) > I use the alarm manager to send > an intent to a service which checks for the time of that event (depends > upon location and the device might have moved) and to see if we are > within 30 minutes of the event. If so, it does something. I would suggest that you give the user configuration ability here. The power drain you are incurring may not be worth it to all users of your app. > Are you saying that the alarm manager is not the correct way to do this > since I should not trigger alarms every 60 seconds? Triggering an event every 60 seconds indefinitely isn't great. Doing so when it is not needed is bad. Not allowing the user to control this behavior would also be bad. Checking location every 60 seconds may get you slapped with a trout, particularly if the user cannot control this behavior.
