Apple patent application could some day help improve the battery life on the Apple iPhone
A patent application filed by Apple could some day lead to longer battery life on the Apple iPhone. The patent, entitled "Inferring user intent from battery usage level and charging trends" explains how the handset can use the battery charging habits of the phone's owner to determine what the phone will be used for at any given time. The battery is then optimized to handle what tasks the owner is expected to use it for next.

To optimize the battery, the screen could darken or brighten and the CPU clock speed could change. While current battery conserving programs wait until the battery is almost dead to implement certain changes to make the remaining battery life stretch out as long as possible, the patent would allow for longer term battery power budgeting so that the battery could last throughout a specific time period.

In one example listed in the patent, an iPhone user puts his phone in Airplane mode on a jetliner. The phone communicates using an API with a program (like eWallet or the calendar, to determine the length of the flight. The phone would then automatically adjust the performance of a couple of programs to ensure that the battery could last the entire flight without charging. Pretty cool, huh?

Another example would be the use of eWallet to purchase a drink at a coffee house. Knowing that you will be getting your caffeine fix for the next 20 to 30 minutes, and that you probably will be playing games during that period of time, the system could spring into action making sure "it is in the user's best interest to sacrifice some battery life in favor of improved performance."
