Apple has introduced an interesting new feature in iOS 18 that allows you to identify if your iPhone charger is running slower than it should. This new feature appears directly in the device’s Settings, making it easy for you to know immediately if your charger is delaying charging your iPhone longer than necessary.
Here we tell you how it works and some tips to improve your charging experience. Are you charging your terminal well?
New alert if our iPhone charges slowly
With the update to iOS 18, users will now find in the Battery section a “Slow Charging” message if the system detects that the connected charger is not providing the maximum charging speed. This message is easily identifiable and is also accompanied by an orange bar on the battery consumption graph, visible in the usage views for the last 24 hours and the last 10 days.
This feature is especially useful for those who are unsure of the actual speed of their charger and want to optimize their iPhone’s charging times.
How do you know if a charger is slow?
There are several factors that can cause a charger to be classified as “slow” by the iPhone. Here are some examples of chargers that commonly offer slower charging speeds:
- Wired chargers that offer 7.5W or less power: these chargers do not meet the ideal speed that an iPhone requires to charge quickly.
- Standard Qi1 chargers (less than 10W): Many wireless chargers on the market are still Qi1, the standard technology, which is considerably slower compared to MagSafe and Qi2.
- USB ports in cars or hubs: These types of ports usually share power between connected devices, so they do not always offer the fast charging that a direct connection provides.
- Chargers with multiple connected devices: If you have a charger that distributes power between several devices, the power may not be enough for a fast charge, since the intensity will be divided between the different devices.
Why is the iPhone charging slow?
In addition to the types of chargers mentioned, there are several situations where an iPhone may charge slower than normal. Some of the most common are:
- Fake or low quality chargers: Although the charger may appear to be designed for the iPhone, unofficial or low-quality chargers may not offer the necessary power, and may even damage the battery. Make sure you have an original charger.
- Accessories connected while charging: If you are charging your iPhone wirelessly and have headphones or other accessories connected, the system will automatically reduce the charging speed to ensure safety, and to manage both the device’s temperature and autonomy well.
- Heavy use while charging: Demanding applications, graphically intensive games, or playing videos with maximum brightness while charging the device will also slow down the charging process.
- Warm environment: Ambient temperature also affects the charging process. If your iPhone detects that it is in a place that is too warm, it can pause charging to prevent overheating. Likewise, if water gets into the iPhone connector, it will not allow you to charge it either.
To get the highest possible charging speed on your iPhone, be sure to use a charger with USB-C Power Delivery technology along with the appropriate cable. iPhone 15 and later models require a USB-C cable for this type of charging, while older models require a USB-C to Lightning cable. Another good alternative is the Apple MagSafe chargerdesigned specifically to offer maximum speed on iPhones, or a Qi2 certified wireless charger.
