Another option is to limit the notifications an app can send. These light up your display, and if there are a lot of them coming in from a particular app, it can make a difference. Notifications for an app can be managed from the same individual listings in Settings where you manage background refresh and location access, or you can go to Settings > Notifications.
You can also eke out a bit of extra battery life by turning off the active listening feature of Siri — if your iPhone is always listening for you to say “Hey Siri,” then that uses up more of your battery. To turn this off, open Settings and choose Siri & Search, then disable the Listen for “Hey Siri” option.
If your battery rate is creeping down past 20 percent and you’re not anywhere near a power source, there are still things you can do. To start, you can enable Low Power Mode.
Low Power Mode reduces the brightness of the display, minimizes system animations, optimizes device performance (so the components aren’t worked too hard), and limits a lot of the activity that happens in the background on your phone.
You’ll automatically get prompted to enable this when the battery level hits 20 percent and 10 percent, but you can actually enable it whenever you like, and it makes a considerable difference in terms of how quickly your iPhone battery drains. To start it manually, open up the Battery menu from Settings and toggle the Low Power Mode option on.
You can also apply many other of the tips we’ve mentioned:
- Turn the display brightness down as far as you can manage.
- Keep your phone locked for as much time as possible.
- Keep your phone in airplane mode for as much time as possible.
- Don’t play any audio or run any games or demanding apps.
- Switch off GPS access entirely via Privacy & Security > Location Services in Settings.
