Proximity Alert and Battery life

 I wrote a simple app that uses proximity alerts and after installing
it on my G1 found that battery life have been halved at least. It's so
bad that phone needs to be recharged mid-day or it completely dies by
9pm. There is no polling of any kind - just proximity alerts (3 of
them). I tried with GPS turned off (using network triangulation for
coarse GPS location) but battery life is still abysmal.

Is there a general solution to improve battery life with proximity
alerts or the whole GPS thing is a non-starter on G1s?

 Just to clarify - I'm not interested in monitoring status of my
I'm interested in finding a solution so that simple proximity alerts
don't destroy battery life and make my apps unusable to users.

Can you elaborate please how I can use Power Management utility to
reduce power consumption of simple proximity alerts?

There are other apps that use proximity alerts -- for example, I would
assume Locale does. Have you tried these applications to see their
effects on battery life?

 I played with it for 15 minutes but never run it for a full day. Will
do though.

1. Application label in the manifest

I am sure this is real simple and I am just missing it...  In the
manifest you can specify a label and an icon for your application that
displays in Android Market.


However, I have noticed that a number of applications also provide a
2-3 line description of the app as well.  I am not seeing you I set
the description string.  What is the attribute name to set that for
the app?  I am assuming I need to set that in the manifest file as
