OS9 Power Saving Mode On Off:

Go to Settings >> Battery;

Turn the Low Power Mode switch on to enter the power saving mode.

When Power Saver is on, the battery icon in the top right corner turns yellow and automatically displays the battery percentage, and when turned on, Mail Acquisition, Background App Refresh, and Auto** are disabled, and some visual effects are reduced or disabled. Charge in low power mode and automatically turn off low power mode when it reaches 80%.

Apple users ushered in the iOS 9 update, and when the iPhone is running low on battery, we can finally cope with this power-saving mode, and the low-power mode is one.

A new feature of iOS 9 that extends the battery life of your iPhone by restricting or disabling certain features.

In addition, some of the phone's sensors, push notifications and background program reorganizing will be turned off. In addition, when the phone goes to sleep, the brightness will also dim, and the processor and network speed will also be reduced.

In fact, as long as the battery level of the user's iPhone reaches 20, iOS 9 will prompt whether to start the feature or not. The same hint recurs at 10%. Of course, we don't have to wait for it to prompt before operating, the above is the detailed method tutorial of iOS9 power saving mode to turn on and off, you can refer to it.

Apple's new power-saving mode is also a highlight of iOS 9, which can extend the standby of Apple devices for three hours after turning on the power-saving mode, and when the power-saving mode is turned on, the battery in the upper right corner of the screen will turn yellow. The power saving mode will limit network activity, cancel automatic email acquisition, cancel app background refresh and **, reduce brightness and some animation effects, and reduce network speed, but it will not affect our normal use.

In the phone's settings, there is a phone battery, and then you will see the power saving mode, and you can turn it off.

How to turn off Apple battery saving mode:

When the phone is low on battery, the phone will prompt whether to turn on the power saving mode.

When you turn it on, your phone's battery icon will be yellow, indicating that it's battery saver mode.

Turn off battery saver mode: Tap Settings.

Tap Battery. Tap Turn off battery saver mode.

At this time, I am looking at the battery icon of the phone to return to normal, which means that the power saving mode has been turned off.

Foreign media reporters first charge the iPhone 6 to a full level, and then use the Watts Up Pro meter, which has input and output power plugs and sockets, which can directly calculate the power consumed. Then you can easily read the power consumption data under various activities through the Logger Pro app, and check the efficacy of the power saving mode by comparing the power consumption of the two modes. This test ignores the power loss in the AC to DC process.

The first test consisted of 400 seconds of standby in standard mode, during which the reporter sent an email to the iPhone 6 to simulate normal use.

Then, in standard mode, the computer is turned on to simulate daily use for 400 seconds, such as opening apps, browsing the Internet, etc.

Repeat the above two processes in the "Power Saving Mode", read the recorded data through the app, and the result is as follows:

It can be seen that in standby use, the power consumption of the power saving mode is 80% of that of the standard mode, and in the daily use scenario, the power consumption of the power saving mode is 90% of that of the standard mode.

The low-power mode principle of iOS 9 is also not complicated, it is achieved by limiting network activity and reducing some performance.

For example, when there is only a lot of power left, the email will not be automatically pushed, and users who need it can manually check whether there is a new email; The auto-refresh and ** of the backgrounder are also turned off; Motion effects and brightness are of course also turned off or down; The speed may also be slowed down, but at least you can still surf the Internet. Apple says that these measures are carried out "silently", and you may not feel that you have entered a low-power mode, except that the user needs to manually turn on the "low-power mode" themselves. After entering this mode, the iPhone can fight for another 3 hours.

In order to make it easier for users to turn on the "Low Power Mode", Apple puts this switch directly to the home page of "Settings" in iOS9, and the battery usage management of iOS8 is placed in the "General-Usage" submenu.

Whenever the battery is left20%,The phone will automatically switch to low power mode,This feeling is very good,But I personally feel that the power consumption speed is not much different if you can't turn it on,Because I have been using the phone,If you say standby in low power mode,It is estimated that it can last longer than when it is not turned on。 At 80% charge, the system will automatically turn off this function.

Everyone has heard of ios

There is a power-saving mode in 9, but there are not many people who can set it. Therefore, I have specially compiled an ios9 power-saving mode setting tutorial for you, I hope you can know how to set the power-saving mode after reading it.

2. Under the setting option under the opening of the iOS9 system, we will find the "battery" item and click to enter the battery option. After clicking on the battery options setting window, we can see that the "Low Power Mode" under its options is turned off.

3. Then, after we find the "Low Power Mode" option in this off state, click the off button behind it with our fingers, and switch to the ON state with one click.

4. Then after turning on the low power mode under the battery option, we will look down to find some apps with a large battery usage, and then close them, so that we can effectively save the power of the phone.

iOS9 Battery Saving Tips:

1.Turn off [Background App Refresh].

Go to Settings. General.

Background app refresh.

Description: iOS

9. After the background application is automatically refreshed, the system will automatically refresh the background content or use location services when the Wi-Fi or cellular network is turned on. I find this very battery draining and highly recommend turning it off.

2.Turn off [AirDrop].

Open Control" Click the airdrop icon to deactivate.

Description: iOS

9. The airdrop function can be shared with nearby friends**,**. But it's best to turn it off when you're not using it, otherwise it will keep searching for nearby compatible peiyin devices, which will cause power consumption.

3.Turn on [Reduce Motion Effects].

Set up. General.

Accessibility. Reduce dynamic effects.

Turn it on. Description: When you move the device, the paper is slightly offset to create a 3D effect. But this may also affect the battery life, and the power consumption is also quite terrifying.

4.Turn off Direct Mail

You can go to the settings.

Mail, Contacts, Calendar.

Get new data.

Turn off the push, and get the item below.

Select Manual. Note: You can manually obtain the latest emails to avoid automatic background fetching by the system to save power.

5.Turn off Unnecessary App Push in Notification Center

Set up. Notification Center.

Description: After the application push code is turned on, once there are new messages and content, it will be pushed to you from time to time, resulting in serious power consumption, and it is very helpful to reasonably manage and set your application push and turn off unnecessary applications for push. You can see that I only set up email push here, and I have closed the rest of the applications, so you can set it up according to your own situation.
