About iPhone charge speeds

Learn how to improve the charging speed of your iPhone.

You might 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 expected 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

With iOS 18, if iOS detects that your charging experience could be improved, you'll see a Slow Charger message in Settings > Battery. This doesn’t mean that there’s anything wrong with your iPhone or charger; it just means that your iPhone could charge faster by using a higher-wattage 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.

Charge faster

Here are a few more ways to speed up charging.

Disconnect other accessories

To comply with regulatory standards, if you charge your iPhone wirelessly while USB-C or Lightning accessories (like headphones) are connected, charging is limited 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.
