Run well on 512Mb devices
Run great on >512Mb

Windows Phone 8.1 goes further to
make the experience more fluid
In Windows Phone 8 apps got a predefined memory cap
Worked well but could be overly conservative
Result:
System monitors how much memory your app is
using over time
Adjusts memory cap for app based on this data
Result
More apps stay in memory
512 Mb – some apps resume
>1Gig – nearly all apps resume

When a user enters that geofence, the app is
triggered and app execution can happen
Geofence notifications can be received in the
background by a background task
