I am making an app that quickly drains the users battery. For this, I am planning on using the sound-framework for vibrating, location services, download large but empty files from the internet, use the flashlight on the back of the phone, and so on. I know these can effectively drain the battery, but I would like to know if there are more methods that are more or equally power/processor-consuming or that could work for this in any way?
Examples on how to achieve 100% CPU usage is also very appreciated.
Thanks.
Here are some of the things you could do (Most of these are possible to do programatically. i.e. they can all be turned on one by one as soon as your app starts) -
Most likely the battery will drain within 2 hours.
One suggested way for you to achieve 100% CPU usage using threading - Background threads consuming 100% CPU on iPhone 3GS causes latent main thread. But be careful...
