Steps
Open Settings, tap Battery and scroll to Battery Usage by App. Check the last 24 hours and the last 10 days to see which apps use the most power.
Turn on Low Power Mode in Settings, Battery when you need to stretch a charge. It pauses background refresh, mail fetch and some visual effects until you charge again.
Go to Settings, General, Background App Refresh and switch it off for apps you do not need. Or set it to Wi-Fi only so mobile data is not used.
Open Settings, Privacy & Security, Location Services. Set each app to While Using and turn off Precise Location where a rough position is enough.
In Settings, Display & Brightness, set Auto-Lock to 30 seconds and turn on Auto-Brightness. Drag the brightness slider down when you are indoors.
Turn off Always-On Display on supported models under Settings, Display & Brightness. The screen then goes fully dark when you lock the phone.
Open Settings, Notifications and turn off lock screen alerts for apps that do not need them. Every notification lights up the screen and wakes the phone.
Remove widgets you do not check from the Home Screen and Lock Screen. Widgets that refresh often pull data in the background all day.
Check Settings, Battery, Battery Health & Charging. If Maximum Capacity is below 80 percent, book a battery replacement at an Apple store or authorised service.
Restart the iPhone and update your apps from the App Store. A new iOS version can keep working in the background for a day or two after install.
Tips and common mistakes
Give the phone two or three days after an update before judging battery life, since background indexing settles down on its own.
Do not force-quit apps from the app switcher all day. Relaunching them from scratch often uses more power than leaving them open.
Keep the phone out of direct sun and off hot car dashboards, because heat damages battery capacity over time.
Questions
Why did my battery start draining right after updating to iOS 27?
A fresh install reindexes photos, files and messages, which uses extra power for a day or two. If the drain continues after that, work through the settings above.
Should I turn Background App Refresh off completely?
You can, but apps like messaging and weather will stop updating until you open them. Turning it off only for apps you rarely use is a good middle ground.
Does Low Power Mode damage the battery?
No. It simply limits background activity, mail fetch and refresh rates to save power, and everything returns to normal when you switch it off or charge past 80 percent.
