iPhone 7 Battery Saving Tips: How to Conserve Power and Make It Last Longer

The iPhone 7 may have one of the best-performing batteries Apple’s made, but even with the efficient A10 Fusion chip, your battery won’t last forever—especially if you’re using power-hungry features all day. Whether you’re trying to squeeze more hours out of a charge or just keep your battery healthy long-term, here’s how to manage and extend your iPhone 7’s battery life.

Check Your Battery Usage and Turn On Battery Percentage

Start by knowing how your battery is doing.

To show battery percentage:

Go to Settings.
Tap Battery.
Toggle Battery Percentage to ON.

To see usage details:

Still in Settings > Battery, scroll down to see which apps are draining your battery the most.
Tap an app to view how much time it’s active on screen vs. in the background.

Lower Screen Brightness or Enable Auto-Brightness

Your screen is one of the biggest power hogs.

To adjust brightness:

Go to Settings > Display & Brightness.
Drag the Brightness slider to the left.

Or turn on Auto-Brightness:

Go to Settings > Accessibility > Display & Text Size.
Toggle Auto-Brightness ON.

Turn Off Raise to Wake

Raise to Wake lights up your screen every time you lift your phone—which adds up over time.

To disable it:

Go to Settings.
Tap Display & Brightness.
Toggle Raise to Wake OFF.

Disable Background App Refresh

Apps that update in the background drain battery even when you’re not using them.

To turn it off:

Go to Settings > General > Background App Refresh.
Select Off or Wi-Fi only, or disable it for specific apps.

Use Low Power Mode

This is the easiest way to stretch battery life when you’re running low.

To turn it on:

Go to Settings > Battery.
Toggle Low Power Mode ON.

It reduces performance and disables background activity—but keeps your phone usable longer.

Set Auto-Lock to 30 Seconds

The shorter your screen stays on, the more power you save.

To adjust auto-lock:

Go to Settings > Display & Brightness > Auto-Lock.
Choose 30 Seconds.

Turn Off Unused Wireless Features

If you’re not using it, turn it off—this includes Wi-Fi, Bluetooth, AirDrop, and even Cellular Data.

To manage Location Services:

Go to Settings > Privacy > Location Services.
Turn it off completely or restrict access for certain apps.

Reduce Motion and Animation Effects

Parallax and zoom effects look nice, but they drain your battery.

To reduce motion:

Go to Settings > Accessibility > Motion.
Turn on Reduce Motion.

Additional Tips for Preserving Battery Life

Condition Your Battery Early On

Let your phone charge to 100% and drain fully a few times during the first week of use.

Avoid Overcharging

Don’t leave it plugged in for more than 24 hours.

Use Your Battery Regularly

Don’t let the phone sit idle for days without charging or use.

Avoid Extreme Temperatures

Keep your iPhone away from direct sunlight or freezing cold environments.

Use Only Apple-Certified Chargers

Cheap third-party cables may damage your battery or cause charging issues.

Turn Off Siri Suggestions

Go to Settings > Siri & Search.
Disable Suggestions in Search and other similar options.

Restart If Battery Drains Abnormally Fast

A simple reboot can stop background glitches that eat up power.

Consider Battery Replacement

If your battery isn’t holding charge and your device is a few years old, have it checked by Apple or an authorized service provider.
