Does iOS 9 Drain Battery? Improvements for Battery Efficiency
In our article What's New in iOS 9, we've introduced the first piece of information: iOS 9 includes a power-saving mode to extend device usage time.
According to Apple's announcement, iOS 9 enhances iPhone battery preservation by introducing new features such as using sensors like proximity sensors to turn off the screen when the device is placed face-down on a surface, even during notifications. These features and others help extend battery life by up to 3 hours per day, adding approximately an hour of usage compared to iOS 8 in normal mode.
Moreover, the Low Power Mode maintains energy, enabling the device to last an additional 3 hours when the battery is low. In iOS 9, users will receive notifications when the battery drops to 20% and 10%, prompting them to actively monitor and utilize the limited battery power as it depletes.
Overall, iOS 9 is evaluated to be more battery-efficient than iOS 8. Users can confidently upgrade by downloading iOS 9 and using it today.
