- 4. Different ways to measure battery consumption: Component level, Device level, Application level In this method, the device power consumption is the aggregate of measured HW Component power consumption at component level level This method is more accurate, and the results are more reproducible and more suited for device OEMs The power is measured at the aggregate point of battery connection in this method, for variety of scenarios of the device usage Device level This method is easier, and more practical for most cases particularly for operators The power is measured for a specific application, based on its demands on specific system resources with material effect on power consumption Application level Consistent power consumption testing during he development phase is the effective way to find power hogs and optimize them Confidential - For internal use only.

- 5. Power consumption testing and optimization go hand in hand. Without measuring and testing, its hard to optimize power usage Measurements need to be repeated to become statistically reliable Power Consumption 300+ samples / sec Testing Repeat for 35 times, and remove outliers Use external measurement tools, internal tools skew the results Define test scenarios that are reproducible (Loading your Facebook page is not a good test case Quick wins Power Optimization GUI optimization: Strategies Reducing cognitive latency, Increasing Visibility, Use of Hot Keys, Darker instead of Lighter Data consumption and radio usage Other strategies: CPU, Memory access (Code optimization) Background processing Confidential - For internal use only.

- 8. Mobile/CE UX is an interactive experience and needs to be designed and tested around different interactive usability dimensions Learnability : How easy it is to use for the first time Mobile/CE Experience Efficiency : How many steps it takes to complete a (key) task Usability dimensions Memorability : Does is get easier as the user repeat the task? Error recovery : How graceful is the error recovery? Accessibility : Easiness and simplicity of accessing (key) tasks Mapping : Does the UI response matches what the user expects? Visibility : Are important information the most visible? Feedback : Is user in control of the UI? And is she kept informed? Consistency : Do like items are displayed and acts the same way? Responsiveness: How responsive the UI interaction is? Confidential - For internal use only. Do not distribute. 7 息 2011 INTUIGENCE Group

- 12. A well data usage optimized mobile app is good business. Its more attractive to users and it often consumes less battery The average smartphone non-streaming application uses 10.7 MB per hour (based on 50 most popular mobile apps, Q1/2011) Why does it matter? Unlimited data plans are HISTORY! Metered data is the only way MNOs will be able to remain viable and profitable businesses Mobile app developers will soon face greater user scrutiny on app data usage More data consumption == Shorter Battery life Compression, Some people are building a business out of this: Onavo Optimization Caching Strategies Delta updates versus full updates Confidential - For internal use only.
