It has been pointed out for more than a year that the iPhone battery is too fast.
However, there are some tricks to reduce battery consumption, so if you are worried about this problem, try it.
One of them is to enable the "low power mode" of the iPhone.
Of course, it can be used manually every time the battery level is reduced, but if it is at a specific time every day, or if the battery level reaches a certain%, automatically becomes "low power mode".You can also do it.
In the initial setting, when the remaining amount of the iPhone is 20%, the state of "low power mode" starts.
However, as the battery of the iPhone gets older, the time from 20%to zero is significantly shorter, so many people are already too late.Therefore, it is an automation that helps.
Apple's "shortcut" app is indispensable for iPhone automation.Downloading and installing this app allows you to run a routine of automation on your iPhone.
After installing the "Shortcut" app, open the app and go to the "Automation" tab.
Press the " +" button on the upper right and tap "Create a personal automation".Now you can decide an automation trigger.If you want to execute "low power mode" at a specific time every day, tap "Time" and select the time and frequency of the automation.
"Next" → "Add action", use the search bar to find "Low Power Mode" and select from the search results.Confirm that "turn on low power mode" in the automatic action, and click "Next".
In the last step, uncheck "ask before execution" and tap "Do not ask" to "complete".
Now, the iPhone automatically executes "low power mode" when the user has selected.
Alternatively, you can execute the same automation when the battery remaining on the iPhone falls below a certain%%.
To do so, create a new personal automation and select "Remaining Battery" as a trigger (instead of "time").
First, use the slider to go to the desired battery level, and when the setting is completed, select "less than x%" (X is the selected percentage value).The remaining procedure is the same as when "low power mode" is set at a specific time every day.
If you are really in trouble, such as forgetting the charger or not using a charging port on a long flight, try this "ultra -low power" shortcut.This shortcut cuts the connecting sensor that consumes batteries such as WiFi and Bluetooth, and eliminates the brightness of the screen.
Now you can keep the iPhone somewhere safely when you need to use the iPhone or until you can use the charger.
