Abstract

Right now, the only way to know that a PDA battery is low is to look at the battery indicator and charge it when it's low (1-2 bars). Frequent charging of rechargeable battery wears it down (decreases battery life). Sometimes the battery dies at most inopportune time (i.e., when one needs to make an emergency call). It would be nice if there is a way for device to intelligently tell you most optimal time to charge it and also avoid these emergency situations The invention is to have a software module on the device that monitors battery consumption and logs it over time. Over a period of weeks, days, etc, software will be able to build a use-pattern and will know when most the most drain is, when least drain is, etc. The software module monitors the drain from certain applications (PHONE, IM, SMS, etc.) and improves the accuracy of the drain estimation. The module can use this data to forecast optimal charging day/time and provide notification (alert) for user to charge the battery. This makes the most efficient use of the battery to extend battery life. Here's a use case: I have 3 bars on my PDA/cell phone on Thursday. Device software notices that the last 4 weekends, I make a lot of calls from my cellphone on the weekend and my battery usually dies if I have 3 bars. It sends me an alert to notify me to charge before leaving for work on Friday evening.
