Apple may be looking to introduce a new battery related feature in its future iPhones. All iPhone users would like to see some improvement, either in the charging aspect or the battery life. But the Cupertino-based tech giant may have set its sights at some other battery aspect for now. As per a newly-granted patent by USPTO, the improvement that Apple is focussing on right now is how to alert the iPhone users when the battery is low. The patent is named “Smart advice to charge notification”. It was filed in 2018.
The abstract of the patent (an excerpt) reads : “Systems and methods are disclosed for advising a user when an energy storage device in a computing system needs charging. State of charge data of the energy storage device can be measured and stored at regular intervals. The historic state of charge data can be queried over a plurality of intervals and a state of charge curve generated that is representative of a user’s charging habits over time. The state of charge curve can be used to generate a rate of charge histogram and an acceleration of charge histogram. These can be used to predict when a user will charge next, and whether the energy storage device will have an amount of energy below a predetermined threshold amount before the next predicted charging time.”
As per Apple’s patent, the notification for low battery arrives too late in modern day smartphones. The arrival of the notification leaves very little time before the phone discharges. It looks like Apple plans to improve this time gap and make the future iPhones send low battery notifications earlier so that the user has enough time to put the device on charge and save time. So, as of now, Apple does not seem to be inclined towards improving the charging speed or the battery life of the iPhone but has taken an indirect approach to tackle the low battery issue.
