About iPhone charge speeds

Learn how to improve the charging speed of your iPhone.

Get a charge-time estimate

With iOS 26, you can go to Settings > Battery to get an estimate of the time needed to charge your iPhone. iOS estimates the time that it will take to charge to 80 percent, or to 100 percent (or your charge limit) if the charge level is over 80 percent. You can also see this estimate near the top of the Lock Screen.

Charge faster with a different charger

For faster wired charging, use a USB-C Power Delivery charger and a USB-C cable for iPhone 15 models and later¹ (or a USB-C to Lightning cable for iPhone 14 models and earlier).

For faster wireless charging, use a MagSafe Charger² or a Qi2-certified wireless charger.

Charging your iPhone might take longer than you expect if you use:

• A wired charger that provides 7.5W or less

• A wireless charger that provides less than 10W, like a Qi1-certified charger

If your wired charger has more than one port, like the 35W Dual USB-C Port Power Adapter, or if you charge with a computer or USB hub with other connected devices, the maximum power output might be reduced. This depends on the combined power needs of all connected devices and on system conditions.

Charge ports in USB hubs or cars might charge slower than a dedicated USB-C charger.

Find out if you should use a different charger

With iOS 18 and later, if a higher-wattage charger could improve your charging experience, iOS will display a Slow Charger message on the Lock Screen and in Settings > Battery. This doesn’t mean that there’s anything wrong with your iPhone or charger. You can tap the Info button to get more information.

With iOS 26, if iOS detects a charger that's connected but isn't charging, you'll see an Incompatible Charger message in Settings > Battery.

Charge faster

Here are a few more ways to speed up charging.

Disconnect other accessories

To comply with regulatory standards, if you connect USB-C or Lightning accessories (like headphones) while wirelessly charging your iPhone, the system limits charging to 7.5W.

If an accessory with power pass-through (like a USB-C Digital AV Multiport Adapter) needs to reserve power for the ports, it might reduce the power delivered to your iPhone.

For faster wireless charging, disconnect wired accessories from your iPhone.

Limit your use of apps

You might notice reduced charging speed if:

• You use graphics-intensive or processor-intensive apps, games, or features, including camera apps

• You stream high-quality video, especially with the display at full brightness

If you need your iPhone to charge fast, limit your use of these apps while charging.

Charge in a cooler place

Your iPhone might get slightly warmer while it charges. Your iPhone might put charging on hold temporarily while in extreme temperature conditions. Charging will resume when the battery’s temperature returns to its normal operating range. Try moving your iPhone and charger to a cooler place.

You can see if charging was on hold on your iPhone by going to Settings > Battery.
