how to fix iPhone 7 Plus fast consumption failure

An iPhone 7 Plus with fast consumption failure, what causes the iPhone battery to consume so fast? Actually, iPhone fast consumption is common problem, the iPhone setting , the iPhone IOS system , the Apps , the iPhone battery , the iPhone motherboard all can cause this failure, so how to fix it?

1. Make Sure The Auto Brightness Is On

For the iPhone display screen, we can adjust the brightness in the system. Someone like to keep their iPhone display always on, but continuous screen brightness consumes a lot of battery power, we can use Auto Brightness function to avoid this case.

In order to make turn on the auto brightness, please go to Settings -> General -> Accessibility -> Display Accommodations. And you can go to Settings-> Display & Brightness to set the time for Auto-Lock.

2. Disable Some Notifications

When you download the new App, they will prompt you that allow notification or not, and you will choose allow it. However, for many Apps, the notification are not necessary，because the notification will consume the power of the iPhone battery.

In order to disable the notification for App, please go to Settings-> Notifications, check NOTIFICATION STYLE, and then tap the App you want to disable the notification, and then turn the button to the left side on Allow Notifications.

3. Turn On Low Power Mode

Low Power Mode will reduce display brightness, optimizes device performance, and minimizes system animations. Low Power mode automatically turns off when your device hits 80 percent charged. After you turn on low Power mode, when your iPhone battery charge is below 20%, it pauses background application refreshes and automatic downloads, so it can maintain the basic functions of the iPhone 7 Plus.

Turn on the lower power mode on iPhone 7 Plus, please go to Settings > Battery, and then tap Low Power Mode.

4. Disable Some Location Service

Most of Apps has location services, and but not all location service are needed. As we know, there are two options for location service on App, one is Never, and the other one is While Using the App. For some App, we can choose never, because the location service will constantly drain your iPhone battery.

In order to disable some location service on App, please go to Settings -> Privacy -> Location Services, tap the Apps that you want to disable the location service, and then choose Never.

5. Other solutions:

- Check iPhone battery

- Check iPhone motherboard

If there is a problem with the iPhone motherboard, then it also will cause the iPhone battery consumption problem. We can disassemble the iPhone to measure the iPhone 7 Plus motherboard.
