After the Batterygate scandal, Apple brought improvements to how it handles processor frequency throttling and the battery charging behavior. It introduced the Optimized Battery Charging feature to iPhones and iPads with the release of iOS 13, which was meant to reduce the overall battery wear, but it doesn’t seem to be working as intended.
According to a report from ZDNet, the Optimized Battery Charging feature isn’t working as it should. When you put your iPhone to charge overnight, the feature is meant to kick in and prevent the battery from being fully charged. It reduces the charging speed so that your phone is only fully charged closer to your wakeup time. This way, the battery isn’t held at its full charge mark for a long time, thereby preventing battery wear.
For the Optimized Battery Charging feature to work, iOS 13 takes into consideration your location history, your sleep and wakeup times, and more to learn your charging behavior and then adjust charging speeds accordingly. But what if your sleep cycle isn’t consistent or if your work hours are irregular? Well, it appears that the feature doesn’t work if that happens.
The report states that Apple could do more to learn your intended sleep and wakeup times, such as having a look at the alarm clock or calendar, but it doesn’t seem to do that. The feature also seems to fail if you break your regular sleep pattern. The operating system takes a few days more to learn your new sleep pattern. Until then, it charges the battery using the normal way.
Moreover, it has been noticed that even when the feature works, it could sometimes be erratic. The report states that the iPhone could charge hours before you are intended to wake up from sleep and shows the notification about when the phone is scheduled to be fully charged. This means that it is wearing down the battery health over a long period of time, reducing battery life.
Apple seems to have very little information on how users can improve the Optimized Battery Charging feature. Using the stock charger or a high-quality third-party charger seems to have helped people, but it is not a sure-shot way. Some users have been able to make the feature work, once it goes astray, by turning the feature off and on again. For others, the device needed a software reset.
While it’s hard for a phone to understand the sleep cycle of a user on its own and adjust frequently, Apple could do more. For instance, it can have a look at the alarm clock, calendar appointments, and integrate with the Apple Watch (for users who have the smartwatch), to improve sleep cycle detection. Moreover, the iPhone maker could offer users an advanced feature where they could manually add their intended wakeup time.
