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



Apple has been researching new ways for users to learn more about the battery life of their devices, and the company seems to be planning to add more related features to iOS. The United States Patent and Trademark Office granted Apple a patent for a new system this week that can predict and warn users when the iPhone battery will run out.

As mentioned before Apple Insider, The patent is described as “smart charging notification suggestions.” This new system will not help maintain internal battery life like some iOS features, but will help users understand how long the battery can last in a day based on recent usage.

On current devices, users will only receive a warning about low battery when the battery is less than 20%, but the patent shows a way to make these notifications more intelligent and personalized. Although this works well in most cases, Apple gave an example where the user forgot to charge the phone overnight and only received a low-battery alert before leaving get off work.

In general, a “low battery”

; indication based on a fixed threshold of the remaining battery power is not received in time for the user to take corrective measures. For example, if a user usually charges a smartphone at night, but forgets to charge it once, he will only receive the “low battery” indication before going to work the next day, and will not leave time for the user to charge the phone before leaving get off work.

If you are a Mac user, you may have noticed that macOS shows the user an estimated battery life-but the patent describes a system that is more complicated than that. For example, it will identify user behavior on different days of the week to adjust daily battery alarms. The system can also operate based on the user’s location, but Apple emphasizes that for privacy reasons, the data will be processed locally.

Given the current charging state of the energy storage device computing system, if the user is unlikely to make a notification before the next high probability charging time, the notification can be sent to the user. […] However, if the analysis of the current and stored charging status information shows that the user will not enter the next high-probability charging time when the battery is not exhausted, the computing device can display a recommendation to charge the notification at 10 o’clock in the evening, even if the current The state of charge is greater than a fixed threshold of 10% of the remaining energy.

Although not necessarily actually using the patents filed by Apple, the company recently added a new battery recalibration tool for iPhone 11 users with iOS 14.5 beta. In addition, iOS also shows the maximum capacity of the device’s built-in battery, so it would not be surprising if Apple introduced similar features described in the patent in iOS 15.
