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

Verb (short for verb) closes system services.
IOS 7 has added utilities such as places near popular applications and frequented places. In fact, the positioning of the iPhone is virtually maintained, and the battery turns off all these unnecessary system services again, which can reduce the loss of power and reduce unnecessary privacy leakage.
Methods: In Settings-Privacy-Location Services-System Services, turn off all system services (PS: If compass and map are used frequently, it is recommended to keep compass calibration on).
Sixth, limit advertising tracking.
At present, iOS 7 has enabled this function by default, and users can realize the function of restricting advertisement tracking without modifying the settings. Advertising tracking function is actually a user privacy issue. Restricting advertising tracking is only beneficial to protecting privacy and improving iPhone experience, but the degree of power saving cannot be measured. No comments here, just recommended settings.
Methods: In Settings-Privacy-Advertisement, turn on the restricted advertisement tracking function (PS:IOS 7 or above is turned on by default, and iOS 6 or below needs to be turned on manually).
Seven, disable the mail push function
The email function of iPhone is praised by people who have used it, and it is easy to make people rely on it. If you don't use email frequently, you don't even have to log in to your account. However, once you successfully log in to the email account, the email App will push new emails in real time by default, and the power consumption can be imagined.
Methods: Get new data in Settings-Mail, Address Book and Calendar, turn off real-time push, and choose the mode of regular or manual acquisition. (PS: If you often send and receive important emails, it is recommended to continue to push)
Eight, selectively disable the iCloud service.
Apple's iCloud cloud service actually has good functions and experience. It is integrated with Apple ID, which is a necessary function of iPhone. However, for some impractical functions, such as photo stream, manuscripts and data, and key chains, it is better to turn them off directly to avoid unnecessary waste of resources.
Methods: In the settings -iCloud, turn off the key chain, photo stream, manuscript and data functions. (PS: In order to ensure a complete iPhone experience, it is recommended to keep the address book, memo and find my iPhone function)
Nine, turn off Bluetooth
Careful users will find that when the iPhone is turned on for the first time, Bluetooth is turned on by default. Not only that, the iPhone will turn on the Bluetooth function by default after every system update. Although Bluetooth may only consume a little power, it is better to turn it off when not in use.
Method: In Settings-Bluetooth, select Close. In addition, the Bluetooth of iPhone is not compatible with the Bluetooth of many Android phones, so it is not necessary to turn on Bluetooth frequently.
X. reducing sound and vibration
It is common sense that the frequent power consumption of mobile phones is also reflected in sound and vibration. Generally speaking, we don't think it is necessary to add vibration when the bell mode is on. In addition, it is worthwhile to minimize some unnecessary sound options.
Method: In Settings-Sound, turn off the "ringing mode vibration" and turn off the key tone and lock tone. (PS: It is recommended to keep the vibration in silent mode, otherwise you may miss important incoming calls or notifications)
