Battery and charging

Why your battery behaves the way it does, and what you can actually change.

Optimized Battery Charging

Available

Your iPhone learns your daily routine and holds the charge near 80 percent, finishing the last part just before you normally unplug it.

Settings > Battery > Charging > Optimized Battery Charging

Battery Health

Available

This screen shows what percentage of its original capacity your battery still holds, and warns you when it has aged enough to affect the phone.

Settings > Battery > Battery Health

Low Power Mode

Available

Low Power Mode cuts background activity and visual effects to stretch the charge you have left, and turns the battery icon yellow while it is on.

Settings > Battery > Low Power Mode

Battery Percentage

Available

This shows the exact charge as a number in the status bar instead of only a battery shape.

Settings > Battery > Battery Percentage

Charge Limit

Available

You can tell your iPhone never to charge past a chosen percentage, so the battery spends less of its life sitting full.

Settings > Battery > Charging > Charge Limit

Battery usage by app

Available

The Battery screen breaks down which apps used your charge over the last day or ten days, and separates screen time from background time.

Settings > Battery

MagSafe charging

Available

MagSafe uses magnets to align a wireless charger with the coil in your iPhone, which charges faster and more reliably than dropping it on a flat pad.

Settings > Battery

Fast charging

Available

With a high enough power adapter, an iPhone can take a large share of its charge in the first half hour, then deliberately slows for the rest.

Settings > Battery

Thermally limited charging

Available

When your iPhone gets warm it deliberately slows or pauses charging to protect the battery, and it may tell you charging is on hold.

Settings > Battery

Peak Performance Capability

Available

This line tells you whether your battery can still supply power fast enough, or whether the phone is limiting performance to stop unexpected shutdowns.

Settings > Battery > Battery Health > Peak Performance Capability

Charging over the wired connector

Available

The wired port charges your iPhone, and on USB-C models it can also send power out to accessories such as headphones or another phone.

Settings > Battery

Clean Energy Charging

Region dependent

Your iPhone can shift part of a long charge to times when the local electricity grid is running on cleaner energy.
