Apple Is Finally Getting Serious About Fast Charging On The iPhone 16 Series, With iOS 18 Now Warning Users If They Use A Slower Charger

All iPhone 16 models now support fast charging up to 45W if you use a wired connection, making it around 50 percent higher compared to the iPhone 15 lineup. This major change alone signifies that Apple has finally become serious about topping up the batteries faster, which should be the case, given that the technology giant was criticized annually every time it announced a new lineup. Fortunately, that is not the only change introduced, as on a software level, users will be warned if they are using a slower charger. That is correct; with the public release of iOS 18, you can now view a notification if your handset is receiving an unoptimal level of wattage.

Just like the iPhone 15 series, iPhone 16 owners can execute a charge limit in iOS 18 to maintain battery health for longer

Last year, with the release of iOS 17, Apple gave iPhone 15 owners three battery health options depending on their preference, bringing a greater level of control to the table. This year, with iOS 18, users will now receive a warning that they are using a slower charger, giving them a better understanding of why their iPhone 16 battery is getting topped up at a slower rate.

To see if the device is receiving a sub-level amount of wattage, you have to go into the ‘Settings’ menu and tap on ‘Battery,’ which will then display a detailed chart. Thanks to Reddit user freaktheclown, we were able to learn that a warning with a yellow text that reads ‘Slow Charger’ will be displayed at the bottom if users are charging their devices with a slower power brick.

Thankfully, this iOS 18 feature is not exclusive to the iPhone 16 series, as the Reddit user posted a screenshot of the iPhone 15 Pro Max. It is a nice touch from Apple to include this information, as customers will be more informed if they should invest in a high-wattage charger to optimize charging on their iPhones.
