A smartphone is only as good as its battery, and ssince the release of the first iPhone, Apple has done its part to make sure you remember to charge it, by giving you a pop-up alert when your charge drops below 20%. While that system is effective, the warning may not come soon enough: if you’re not near a charger and that last 20% counts, especially with an older iPhone, can be tricky. But IIf you need an earlier reminder, you can set a custom battery alert.
Rather than an option in Settings, this is something you have to build yourself using the Shortcuts App to make an automation. Automations differ from shortcuts in that they are designed to fire automatically based on a set of variables, rather than waiting for you to activate them, and yYou can create an automation that will notify you when your battery has reached a certain percentage†
To get started, open Shortcuts on your iPhone, tap the “Automation” tab at the bottom of the screen, then choose “Create Personal Automation.” Scroll down, then tap Battery Level. Here you can move the slider to any percentage you want. Let’s assume 30% for this example. Here you will see this changes your three options: “Equals 30%”, which will alert you when you reach 30%; “Rising above 30%”, which warns you when you go above 30%; and “Drops below 30%”, which sends an alert when your phone drops below 30%.
For our purposes, your best bet is probably “Falls Below” as “Equals” will send you an alert both when your battery hits 30% on its way down, but also when it hits 30% when charging from below. Of course that means that you really get a warning of 29%: If you want to be warned Bee 30%, you need to set the slider to 31%† On the other hand, if you are someone who is careful not to charge your iPhone to 100%, you could choose “Rise Above” to ensure that you receive an alert to detach unplug your iPhone when it reaches 80% for example(but you too does not have to worry too much about your iPhone battery status† Once you’ve chosen, tap Next, then on the following screen: tap ‘Add action’.
huhHow you approach the alarm is up to you. To see a simple notification, search for “Show notification” and replace the text with something that lets you know that your battery has reached the level that UVe chosen. Tapping the arrow gives you additional options, including giving the notification a title, choosing whether the notification plays a sound, and choosing whether the notification has an attachment. You can tap the play button to to test your settings†
There are alternatives to the traditional screen also alert: If you search for “Speak Text” instead, Siri will speak anything you enter in the “Text” field when your battery reaches a certain percentage. If you tap the arrow, you can change options such as the speed and pitch of the voice alertthe language of the voice, as well as that Siri voice you want to use.
WOnce you’ve made your alert choice, tap Next and turn off Ask Before Running. When enabled, this setting forces you to approve the automation before running, which defeats the purpose of an automatic battery warning† Tap Done to capture everything.
If you want to go one step further, you can also set an automation to automatically switch Energy saving mode at any battery percentage you want† That way, you don’t have to wait for the 20% battery warning (or your new custom notification) to be reminded to enable iOS’ battery saver option.
