Power-saving mode is one of the power management schemes for smart phones (including other digital products), which can prolong the standby time after the phone is turned on. In addition to this mode, some mobile phones also have performance mode, super power saving mode and other programs to meet the different needs of users for mobile phone performance and battery life.

After the smart phone turns on the power saving mode, the battery life can be relatively extended. In essence, turning on this function is very useful and will not damage the hardware and software of the mobile phone, but the power saving mode will reduce the hardware performance of the mobile phone and affect the actual experience effect.

Matters needing attention for smart phone to start power saving mode:

1. After turning on the power saving mode, the battery life of the mobile phone can be greatly extended, so turning on this function can increase the standby time of the mobile phone when necessary. When the power-saving mode is turned on, smartphones usually reduce the processor frequency, turn off the high-power core, and reduce the resolution and brightness of the display screen.

2. Background refers to some programs that still reside in memory when the APP form is closed. Frequent background activities will increase the consumption of battery power. For example, the WeChat background will continue to monitor and receive messages from the server.

And show it to the user through the system "notice". Therefore, when the power saving mode is turned on, the system will restrict the activities of these apps in the background or reduce the refresh frequency, and some optimized power saving schemes will even directly close the data connection of the apps.
