Facebook’s iPhone application is eating away at the battery life on iPhones around the world. While everyone is looking to Facebook to fix the code that keep the app running in the background, questions should also be asked of Apple. Isn’t the walled garden of iOS meant to keep badly programmed and over-eager applications away from my smartphone?
The starting point is Facebook’s iOS application. When it is put into the background on an iPhone it should sleep and go into a dormant state. Instead the application continues to drain battery power from an iPhone, reducing the life of the smartphone, with some users reporting the app is consuming 15% of total battery life over a one-week period.
