Apple’s patent reveals a new system for predicting when your iPhone will run out of battery - 9to5Mac

The US Patent & Trademark Office this week granted Apple a patent for a new system that can predict and warn the user when the iPhone battery is expected to run out.

As noted by Apple Insider, the patent is described as a “smart advice to charge notification.” Instead of helping to preserve internal battery life as some iOS features already do, this new system would help users know how long the battery will last during the day based on their recent usage.

Often, a “battery low” indication that is based on a fixed threshold of charge remaining is not received in time for the user to take a corrective action.

If you’re a Mac user, you’ve probably noticed that macOS shows the estimated battery life to users — but this patent describes a more complex system than that.

Given a current state of charge of an energy storage device computing system, a notification can be sent to the user if there is a high probability that the user is unlikely to make it until the next high probability charge time.

[…] However, if analysis of the current, and stored, state of charge information indicates that the user will not make it to their next high probability charge time without running out of energy, the computing device can display an advice to charge notification at 10 p.m., even though the current state of charge is greater than the fixed threshold of 10% remaining energy. .
