In one example of how Apple’s patents might be used it suggests that if your iPhone charge typically runs out on Thursdays only, then your different behavior on that day makes it necessary to reconfigure your power management system for that day only. This might mean looking for patterns in behavior to find when a user is unlikely to use their iPhone (when it is put into Airplane Mode, for instance) and sacrificing performance during these periods, knowing that the user is less likely to be using the device at this time.
Conversely, the iPhone can also intelligently learn a user’s workday by looking at which time periods in a day (e.g. 9:00 am to 11:00 am, and 2:00 pm to 4:00 pm, Monday to Friday) full operating power is likely to be required, and conserve battery for these times.
That is a brilliant idea and will help when it comes to battery life a lot. I think we will get more and more intelligent power handling in our mobile devices. The user doesn't want thick and heavy devices, so we need to have these kind of technologies developed.
Hopefully Apple adds this into iOS 8 already this year.
