1. Motivation
- Smartphones are truly personalized computing devices
- Only one dominant user per smartphone
6. Case study: Optimizing restart ratio of apps.
- The Android default app killer
- Limiting the number of the backgrounds apps lower than the predefined maximum number (15)
- Terminating an app which is least recently used (LRU)
- The problem of the default app killer
- Restart ratio of apps is high because it does not recognize the single user's app usage tendency (In our study, most users experience restart ratio more than 10%)
- Optimizing the restart ratio exploiting our proposed AUM
- Improving the performance of Android's app killing/restarting policy
