For my application, I want to have a Notification sent to the user at a specified time. To do this, I have set up a Timer and the corresponding TimerTask. To be sure the Notification will be sent to the user even if the phone is aslept, I have acquired a PARTIAL_WAKE_LOCK. The problem is that this method draws a lot of power from my battery (my application is responsible for more than 50% of all the power consumption at the end of the day).

Is there another way (a more power efficient one of course) to do what I want to do?

Thanks in advance for the time you will spend trying to help me.

You can use an the android AlarmManager for this.

See Using AlarmManager to Schedule Activities on Android as a tutorial and example.
