If you often use the Spotlight smart search function, it is a smart way to save electricity by limiting its search range. Few people know this trick ~

The powerful function of spotlight can be described as madness. It can search all the information in your mobile phone, even after you delete it. This actually consumes a certain amount of processing power, and we can turn off the content that doesn't need it to search to save electricity.

In settings > general > in Spotlight search, you can check the range you want to search at will.

Turn off background application refresh.

Turning off the background application refresh can effectively improve the battery life of the iPhone, which is basically included in one hundred power-saving tutorials. So, if you really want to maximize the battery life of the iPhone, turn this function off. Turning off the background application refresh has a considerable impact on energy saving. We can compare the power consumption gap of switching function by setting the battery.

Turn off automatic downloading and updating of applications.

Go to Settings -“iTunes Store and App Store, and turn off the "Use cellular mobile data" option. At this time, the iPhone will only be updated in the Wi-Fi environment. If the automatic update option is completely turned off, you can update it manually according to your own needs.

Don't use dynamic wallpaper

After iOS7, the iPhone added the function of "dynamic wallpaper". Although the dynamic wallpaper looks cool, it also consumes a lot of power ... When the dynamic wallpaper moves, your electricity will also "move". So, if you don't like dynamic wallpaper, don't use it.

In addition, 3D Touch wallpaper, which can only be used by iPhone6s and iPhone6s Plus, consumes a lot of power, so it is best not to use it.

Disable location services for some applications.

Location service is a very important function. Maps, weather and other apps need to open location services to provide us with information. However, some applications have nothing to do with positioning, but they need to start positioning services, which will cause unnecessary power consumption for us. For example, on my iPhone, there are unrelated applications such as video software and menu software, which need location permission. 、

In order to improve battery life, it is very necessary for us to disable the location service of some applications. Go to Settings-Privacy-Location Services and turn them off one by one.

Turn off the brightness level.

With IOS7 and later iOS8 and iOS9, the iPhone can adjust the screen brightness by external light intensity. However, turning on this function will consume a lot of power. Although turning off this option may make it difficult for you to see the screen clearly in direct sunlight and won't let you enjoy the highest resolution of iPhone, it is a wise decision if you can save electricity. What's more, it's really ugly, and we can manually adjust the screen brightness of the iPhone.

To turn this option off, click Settings >; Display and brightness ",and then turn off the automatic brightness level.

Close the places you often go.

By default, the iPhone will count the places you often go, and analyze and locate where your home is and where your work is based on the time you stay. Does it sound terrible? )

When iOS7 first introduced this feature, many people used this feature to check their other half. After all, this function can be recorded wherever it goes. At the same time, the frequent statistics will also consume the power of the system. In order to improve battery life and prevent after-the-fact inspection, we should turn off this function!

Avoid cold and heat.

Extreme temperature is very harmful to the iPhone battery. Now in winter, I think my friends in the north have experienced the cliff-like decline of iPhone power, which is caused by the low temperature. Therefore, try not to use the iPhone in extreme temperatures.

Apple officially pointed out that 16℃-22℃ is the most ideal temperature range. When exposed to an environment above 35℃, the storage capacity of the battery will be permanently damaged even if the mobile phone is charged or not. If it is in an environment below 0℃, the battery life will also be temporarily shortened.
