Apple introduced a power-saving feature called "Low Power Mode" in iOS 9, which further extends battery life when the iPhone is low. In order to save power, the system will reduce its performance and turn off background activities in this mode. So how much impact does the low-power mode have on iPhone performance? A few days ago, the media released detailed test results. Under normal conditions, the iPhone 6 Plus scored 1606 and 2891 in the Geekbench 3 single-core and multi-core tests, respectively. When the low power mode is turned on, the score is reduced to 1019 and 1751 respectively. It can be seen that the low power mode will greatly limit system performance after being turned on. At the same time, the tests performed on the iPhone 5s also yielded similar results. Under normal conditions, the device scored 1386/2511 in the single-core/multi-core test, while the score after turning on the low-power mode was reduced to 816/1405, and the performance dropped by about 40%. When the iPhone has only 10% or 20% power left, the system will let the user quickly turn on the low power mode through the pop-up window. In addition, you can also enable this feature in the battery compartment of the settings app. In addition to reducing CPU speed, low power mode also disables mail acquisition, background application refresh, dynamic effects, and dynamic wallpaper. When this mode is turned on, the battery icon in the upper right corner of the screen turns yellow. The low power mode extends the iPhone's battery life by up to 3 hours. And even if you don't turn it on, iOS 9 itself will give you an extra hour of use for battery life optimization.
