Do you have a problem that your iPhone no longer charges? Unfortunately, it is a known problem for some. The cause of an iPhone charging more can have several causes.
The most obvious causes usually lie in the peripherals or housing of the iPhone itself. Rarely is a software problem the cause of an iPhone no longer charging.
However, since iOS 15, a feature has been added in iOS that makes it appear as if the iPhone is no longer charging. This feature is called “Optimized Charging” and does not fully charge the iPhone to extend the battery life of the built-in battery.
In this article I offer several tips that can solve the problem. I recommend reading each tip, implementing them as necessary, and checking if the problem is resolved.
iPhone no longer charges
Disable optimized loading
Optimized Charging is a feature in iOS that helps slow the aging process of the built-in battery in your iPhone. Optimized Charging does this by learning the charging routine of your iPhone. Once it has established the charging routine, it will only fully charge the iPhone (>80%) when you need it.
If you want to charge the iPhone to 100% every time, disable this function.
Open the settings on your iPhone. Then press “Battery” and then “Battery Condition”. Then disable “Optimized Charging”.
Check the iPhone case
If you are using a case on your iPhone, check that the case does not block connecting to the lightning port on the bottom of your iPhone. Sometimes a case partially blocks the lightning port, causing the cable to no longer connect properly, resulting in the iPhone no longer charging.
If you are using wireless charging, check that the case is not blocking charging and that the wireless charging pad is turned on. All cables in the wireless charging station are properly connected, the physical on/off button is on and the plug is properly inserted into the socket or USB port.
software update
Make sure you have the latest version of iOS installed. It adds up Apple rare, but a new version of iOS (if available) could easily solve the problem.
Open the settings on your iPhone. Press General and then Software Update. Check if a new iOS software update is available. Download the update and install the update. I also recommend changing “Automatic Updates” to “On”.
Check the iPhone charger
To rule out why this iPhone is not charging, you can check whether the charger still works. If you have another iPhone, place the extra iPhone on the charger and check whether it is charging. If this iPhone does not charge either, the charger may be broken, replace the charger.
Furthermore, do not use iPhone chargers that you buy from a Chinese webshop. Only use iPhone chargers that have been found suitable for charging from renowned brands.
Cleaning the Lightning charging port
On your iPhone, there is a lightning port at the bottom. This is the port where the charging cable goes in to charge your iPhone via USB. If there is dust or dirt on or in this lightning port, the iPhone can no longer charge properly. So check that the lightning port is clean and/or there is no dust on it. Check the same on the charger itself that is plugged into the socket.
Check the charging cable for breakage
A cable can be broken, so check with another charging cable whether the charging cable is not broken, has a poor connection and whether it is an official cable. Again, do not use cheap cables, as they may provide too much or too little power, resulting in damage to the iPhone or the charger itself.
Restore iPhone to default values
Finally, once you have checked everything, you could reset the iPhone. With a reset you return all settings to factory settings, every adjustment will be undone. If the iPhone still does not charge after this and you have checked the above, consider reporting the iPhone for repair Apple Support.
I hope this helped you. Thank you for reading!
