Close AirDrop
If you're not going to use the AirDrop feature in iOS 7, it's best to turn it off because it's always looking for compatible devices. Airdrop can be closed at the control center.
Background Application Refresh
When you go to Settings > general > Background application refreshes, you can decide which applications can refresh content in the background or use location-based services in the Wi-Fi or mobile network. In addition to setting up a separate application, you can simply turn off the feature completely.
Reduce dynamic effects
IOS 7 adds interesting parallax effects, and when you move a device, the wallpaper is slightly offset to produce a 3D effect. But this may also have an impact on your life, and you can turn it off in Settings > general > Accessibility > Reduce dynamic effects.
Turn off mail push
If you don't need to get a push when you receive a message, you can go to Settings > mail, contacts, calendars > get new data to turn off the push, and then in the "Get" column below Select the system to get mail information, including every 15 minutes, every 30 minutes, every hour, or manually (that is, never get it automatically). This setting will save a lot of electricity.
Brightness settings
The effect of screen brightness on the endurance is believed to be well understood. You can enter the settings > wallpaper and brightness to adjust the screen brightness to medium, or turn on the automatic brightness adjustment function. In addition, you can do these things in the Pull Control center menu.
Turn off all notifications that do not have to be applied
All kinds of apps want to give you a reminder, but many of them are useless and will only make you hate and increase power consumption. So you can go to the setup > Notification Center to turn off unwanted application drives.
Turn off all location-based services that do not have to be applied
Positioning has always been a big spender, so you should make sure that applications that don't need it don't use it. Go to Settings > Privacy > Positioning Services, and you can see what applications are available to the service and turn off unnecessary applications. Of course, you can also completely shut down the positioning service.
Locating services that turn off system functionality
Do not know if you have noticed, your device will always be in the background of a lot of positioning, to pass some actually very useless features. You can go to setup > Privacy > Positioning Service and then select the bottom of the "system services" and then you can choose which features you don't need at all, we recommend turning off diagnostics and dosage, location-based iad ads, and popular apps nearby.
Stop iOS 7 from tracking your location.
IOS 7 has a feature called the geo-fence, which always tracks your most frequented locations, and never caches relevant data in the vicinity. In setting up > Privacy > Positioning Services > System services, you can see where you go most often. If you are worried, you can simply turn off this feature.
Turn off unwanted applications
Apple's new multitasking feature is easy to use, and it's easier to turn off apps. Apple says backstage apps won't do anything, but if you don't believe it or have obsessive-compulsive disorder, you can double-click the home key to turn it off by sliding up the back end of the application.
Limit Siri
Go to setup > General > Siri to turn off Siri's lift to speech function.
Turn off Bluetooth
If you find that the system has Bluetooth enabled, you can quickly turn it off in the notification center.
Battery percent
It doesn't save electricity, but it will keep you from worrying about the consumption of electricity. You can turn off the display of the battery percentage in Settings > General > Usage.
Flight mode
Although the flight mode is basically nothing, but in this mode, almost all of your equipment will not consume power. Flight modes can also be opened quickly in the notification center.
