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

Apple has been working on new ways to let users know more about the battery life of their devices, and it looks like the company plans to add even more related features to iOS. The U.S. Patent & Trademark Office this week granted Apple a patent for a new system that can predict and alert 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 maintain the internal battery life that some iOS features already do, this new system will help users know how long the battery lasts during the day based on their most recent usage.

On current devices, the user only gets a low battery warning when it reaches 20%, but the patent shows a way to make these messages smarter and more personal. While this works well in most scenarios, Apple provides an example where the user forgets to recharge the phone overnight and only gets the low battery alarm before traveling to work.

Often, a “low battery level” indication based on a fixed residual charge for residual charge is not received in time for the user to take corrective action. For example, if a user typically charges their smartphone at night but forgets to do so on an occasion, it does not give the user time to charge their phone before work when he receives a “low battery”

; just before traveling to work it next day. .

If you’re a Mac user, you’ve probably noticed that macOS shows users’ estimated battery life – but this patent describes a more complex system than that. For example, it would identify user behavior on different days of the week to adjust the battery alerts for each day. The system also works based on the user’s location, but Apple reinforces that the data will be processed locally due to privacy.

Given the current state of charge of an energy storage device’s computer system, a message may be sent to the user if there is a high probability that the user is unlikely to achieve it until the next charging time with high probability. […] However, if analysis of the current and stored state of charge status indicates that the user is not reaching the next charging time with high probability without running out of energy, the computer device may show an advice that charge message at. even if the current state of charge is greater than the fixed threshold of 10% residual energy.

Although not necessarily actually patented by Apple, the company recently added a new battery calibration tool for iPhone 11 users with iOS 14.5 beta. In addition, iOS also shows the maximum capacity of the device’s internal battery, so it will not be a surprise if Apple introduces a feature like this described in the patent with iOS 15.
