Having a smartphone shouldn't mean needing to carry a charger everywhere, but sometimes your phone just can't hack it past dinner. While lithium-ion batteries naturally lose capacity over time, one of the more immediate drains is unnecessary high-performance features -- often ones you don't even need or use.
Your iPhone has a few key settings that drain your battery in the background. The good news is, you can turn them off. Instead of watching your battery percentage plummet at the worst possible moment, a few simple tweaks will give you hours of extra life.
Before you even think about buying a new phone, check your Battery Health menu (anything above 80% is decent) and then turn off these three settings. It's the easiest way to make your iPhone battery last longer, starting right now.

Turn off widgets on your iPhone lock screen
All the widgets on your lock screen force your apps to automatically run in the background, constantly fetching data to update the information the widgets display, like sports scores or the weather. Because these apps are constantly running in the background due to your widgets, that means they continuously drain power.
If you want to help preserve some battery on iOS 18, the best thing to do is simply avoid widgets on your lock screen (and home screen). The easiest way to do this is to switch to another lock screen profile: Press your finger down on your existing lock screen and then swipe around to choose one that doesn't have any widgets.
If you want to just remove the widgets from your existing lock screen, press down on your lock screen, hit Customize, choose the Lock Screen option, tap on the widget box and then hit the "—" button on each widget to remove them.
If you're already low on battery, it's best to just switch to a wallpaper that doesn't have lock screen widgets.
Reduce the motion of your iPhone UI
Your iPhone user interface has some fun, sleek animations. There's the fluid motion of opening and closing apps, and the burst of color that appears when you activate Siri with Apple Intelligence, just to name a couple. These visual tricks help bring the slab of metal and glass in your hand to life. Unfortunately, they can also reduce your phone's battery life.
If you want subtler animations across iOS, you can enable the Reduce Motion setting. To do this, go to Settings > Accessibility > Motion and toggle on Reduce Motion.
Visual tricks like the parallax effect are fun, but they can affect your battery life.
Switch off your iPhone's keyboard vibration
Surprisingly, the keyboard on the iPhone has never had the ability to vibrate as you type, an addition called "haptic feedback" that was added to iPhones with iOS 16. Instead of just hearing click-clack sounds, haptic feedback gives each key a vibration, providing a more immersive experience as you type. According to Apple, the very same feature may also affect battery life.
According to this Apple support page about the keyboard, haptic feedback "might affect the battery life of your iPhone." No specifics are given as to how much battery life the keyboard feature drains, but if you want to conserve battery, it's best to keep this feature disabled.
Fortunately, it is not enabled by default. If you've enabled it yourself, go to Settings > Sounds & Haptics > Keyboard Feedback and toggle off Haptic to turn off haptic feedback for your keyboard.
Every single time you type, you'll feel a slight vibration for each key you hit.
