How to save power for iphone:

First, reduce the screen brightness.

The biggest killer of mobile phone battery is not CPU, not making phone calls, but the bigger and bigger mobile phone screen. The default setting of iPhone is to automatically adjust the screen brightness. Under strong light conditions, mobile phones usually work at the highest brightness. The power consumption at this time can be measured by the speed of two minutes 1%, especially when playing games. To save electricity, we must first break the bottleneck of the mobile phone screen.

Reduce the brightness of the screen.

Methods: In Settings-wallpaper and brightness, turn off the "automatic brightness level" of the mobile phone and keep the screen brightness at about 40%. It can not only meet most conditions of use, but also obviously control the shutdown speed of iPhone.

Second, turn off push notifications.

Why the mobile phone consumes so much power is simple, because you use it all the time. But have you noticed that sometimes it will keep ringing when I don't really want to use it? Yes, you have been enslaved by the ubiquitous notice. Don't worry, you have two ways to deal with it.

Methods: 1. For newly installed software, always select "Do not allow sending push notifications"; Second, for the installed software, in the setting-notification center, selectively shut down or shut down all.

Turn off push notifications

It should be noted that when you choose to turn off application notifications completely, you won't receive any push notifications, including important notifications such as QQ and WeChat, unless you open them manually. Be cautious about heavy users of WeChat and laugh at your suggestion. Don't miss big events to save electricity.

Third, the background program refresh is prohibited.

A large part of the power of the mobile phone is lost unintentionally, probably because the background program of the mobile phone has been working. An important function of iOS 7 is that every time you open a program, the content is ready for you. If you are used to updating content after opening a program, you can completely disable the background refresh function of all programs.

Disable background application refresh

Methods: Turn off the background application refresh function in Settings-General-Background application refresh.

Fourth, it is forbidden to send diagnostic data.

When the iPhone is activated, it will ask the user whether to send "diagnosis and consumption data" to the Apple server. Generally it will choose "No". The first is to save electricity, and the second is to protect the privacy of personal data. If it is not necessary for development and testing, there is no need to send feedback at all, because it sends data to the Apple server every day. Undoubtedly, forbidding to send diagnostic information can reduce the power consumption of mobile phones.

Do not send diagnostic data.

Methods: Select "Do not send" in Settings-General-About this machine-Diagnosis and Dosage.
