There are a wide range of tips and tricks that are used to boost mobile performance and there are new ones being discovered by performance experts and enthusiastic developers the world over. However the vast majority of these are focussed entirely on driving the performance of the individual application with no thought to the wider impact on the user.

This session will take several of these tips and tricks and examine whether there are also negative impacts associated with these.

For example regular proactive caching of data on the device is a fairly commonly used practice and would probably be described as best practice for high performance of a data driven app; but what is the impact on battery life and how does this vary between 3G, 4G, wifi and offline? What is the impact on data usage – how much could this practice cost your user?

The session will then compare the impact of these against less performant alternatives and recommend some best practice.

The session will also cover the more philosophical question of whether or not we should care about this or whether the performance of the app is more important to users than these wider concerns. Assessing aspects such as the impact of being regarded as a “bandwidth hog” or a “battery drainer”.
