iPod Touch Power Management

We are a corporate customer who uses the iPod Touch to deliver a mobile solution geared for the healthcare/senior care industry.

Our app is currently delivered using wifi enabled iPod Touch devices leveraging the customer premise wifi network.

We've had some consistent complaints from customers that wifi connectivity with the iPod touch devices is inconsistent. After conducting a substantial amount of data collection at three customer sites, it appears that iOS power management is contributing to the issue on some level.

However, documentation is not readily available to help us understand how iOS power management works, and it what scenarios it will throttle power to the wifi radio. Our data suggest taht the following metrics have an effect on power management of the wifi radio:

- inactivity (guaged by screen touches, not accelerometer)

- weak wifi signal from the Acess Point (ipod will disconnect from a weak signal, while other devices remain connected)

- battery charge level (under 20% much more likely to experieince wifi issues)

Two questions:

- Where can we review more detailed documentation to help us understand how iOS power managment functions?

- How can we begin a dialogue to have Apple work with us to resolve (or provide some level of control over) these power issues?
