Apple has rolled out its latest iOS 18 update, arriving just in time for the iPhone 16 series launch.
One of the most intriguing features of this update is the slow charger warning—a new functionality that aims to keep users informed about their charging habits.
This feature adds another layer of control, especially for those keen on taking advantage of their iPhone’s fast-charging capabilities.
What’s New in iOS 18?
The iOS 18 update, released on September 16, comes with several enhancements to boost the iPhone experience.
Along with a variety of interface tweaks and performance improvements, one notable addition is a warning system that tells users when they are using a slow charger.
If you’re someone who relies on fast charging for your day-to-day needs, this feature will be particularly helpful.
A slow charger warning will now appear in the Battery section of your iPhone’s Settings app, identifying periods when your charger isn’t up to the mark.
This warning is represented in a new orange color on the battery level graph, distinguishing it from the green sections that indicate fast charging.
How Does the Slow Charger Warning Work?
The slow charger warning feature is designed to notify users when their iPhone charger is delivering less power than required for fast charging.
However, Apple has not yet disclosed the exact charging speeds that will trigger this alert. While reports suggest the iPhone 16 series might support charging speeds of up to 45W, Apple’s official spec sheets mention USB-C charging at 20W and MagSafe charging at 30W.
Until Apple provides more clarity, users may have to test this feature with different chargers to see when the slow charger warning appears.
Battery Controls
Beyond the slow charger warning, iOS 18 also introduces more granular control over how much your iPhone charges. Users now have the option to set charging caps at 85%, 90%, and 95%, alongside the existing 80% cap.
This is an excellent feature for those looking to preserve their battery’s long-term health.
Why is this important? Lithium-ion batteries, which power most modern smartphones including iPhones, tend to last longer when charged between 20% and 80%.
By setting a charging cap, users can help extend the overall lifespan of their battery, which is a consumable component and will degrade over time.
Why Battery Management Matters?
Battery health is often overlooked, but it’s a critical aspect of keeping your phone running smoothly for the long haul. With the slow charger warning and new battery controls, Apple is giving users more tools to manage their device’s power consumption better.
Overcharging or consistently using slow chargers can lead to poor battery performance and a shorter lifespan. The new iOS 18 update encourages users to adopt healthier charging habits, ultimately leading to a better iPhone experience over time.
Bottom Line
With the release of iOS 18, Apple is doubling down on enhancing user control over battery performance and charging speeds. The slow charger warning serves as a helpful reminder to make the most of your iPhone’s fast-charging capabilities, while new charging caps allow for better battery preservation.
As we wait for more information on what Apple defines as “fast charging,” this feature is a step forward in promoting more mindful charging habits.
If you haven’t updated your device yet, it’s time to explore the new battery-saving features that come with iOS 18.
