Apple does not provide a direct way to check the charging rate on your phone. However, there are Apple Store Apps like Ampere Battery, Mister Battery, and others that can show you your charging rate by running a short timed test and measuing the differences in your power. Additionally, there are shortcuts like Battery Charging Utility or Battery Charge Logs that may meet your needs. If those options don’t work, Apple Support states that “You can fast charge your iPhone 8 and later to 50 percent battery in around 30 minutes.” So to test it you can deplete your battery to near 0%, set a timer for 30 minutes, and confirm whether or not the battery level reaches 50% (or above) after the timer goes off.
There’s no question that charging an iPhone has become much faster with the new rapid charging technologies built into the iPhone so it’s always a good idea to make sure you’re taking advantage of that. If you have an iPhone 8 or later and it supports fast charging, make sure you’re using a compatible charger and a USB-C to Lightning cable or USB-C to USB-C cable to ensure compatibility.
