Choosing the right wireless charger for your iPhone
Wireless charging. Convenient. No hassle with cables. But which charger is truly right for your iPhone? You've probably bought a charger that charges excruciatingly slowly. Or one where your phone keeps sliding off the charging pad. Frustrating.
However, the problem often lies not in the charger itself—but in what you forget to consider when making your choice. Most people only consider price and design. While the combination of wattage, positioning, and your phone case determines whether wireless charging is a blessing or a nuisance. Just like choosing the right accessories or AirPods for your Apple ecosystem, it's all about the details no one tells you. We'll dive into what really matters when finding that perfect match between your iPhone and a wireless charger.

Why wireless charging for your iPhone?
Wireless charging is more than just a convenient feature—it's a way to extend the lifespan of your charging port. Every time you plug and unplug a cable, wear and tear occurs. With heavy use, this can lead to a loose connection or dust buildup in the port.
The technology works via inductive charging. Your iPhone has a coil inside that captures energy from the charger. This process only works when both coils are properly aligned. That's why positioning is so important—a millimeter difference can make the difference between fast charging and no charging at all.
Which iPhone models support wireless charging?
Not every iPhone can charge wirelessly. The feature was introduced with the iPhone 8 and iPhone X in 2017. Since then, all newer models support this technology:
- iPhone 8 and 8 Plus
- iPhone X, XR, XS, and XS Max
- iPhone 11, 11 Pro and 11 Pro Max
- iPhone 12 series (with MagSafe support)
- iPhone 13 series (with improved MagSafe)
- iPhone 14 series
- iPhone 15 series (with Qi2 standard)
The newer models from the iPhone 12 onwards have an added bonus: MagSafe. This magnetic technology ensures perfect alignment and faster charging up to 15W, while older models only reach a maximum of 7.5W using standard Qi chargers.
Different types of wireless chargers
Flat charging pads
The most common option. You lay your phone flat on a surface. Advantage: compact and affordable. Disadvantage: you can't see the screen clearly while charging. Ideal for the nightstand or desk where you can rest your phone for a while.
Standing chargers
These hold your iPhone upright or at an angle. Perfect for video calls or checking notifications while working. The angle is usually adjustable, allowing you to use it in either portrait or landscape mode. Note: Some models charge more slowly in portrait orientation due to poor coil alignment.
3-in-1 chargers
For the Apple enthusiast who has it all. These stations simultaneously charge your iPhone, Apple Watch, and AirPods. Perfect for the nightstand—one cable for all your devices. It's a higher investment, but you save space and avoid cable clutter.
Power banks with wireless charging function
Charge on the go without a cable. These portable chargers attach magnetically (with MagSafe models) or simply rest against your phone. Capacity ranges from 5,000 to 20,000 mAh. Keep an eye on the weight—a larger capacity also means more weight in your bag.
Wattage and charging speed explained
Wattage determines how quickly your battery charges. But more wattage doesn't automatically mean faster charging. Your iPhone has a maximum it can handle:
- Standard Qi chargers: up to 7.5W for iPhone
- MagSafe Chargers: Up to 15W for iPhone 12 and later
- Qi2 chargers: also up to 15W, but universal
A 10W charger won't charge your older iPhone any faster than a 7.5W model. That extra power is lost as heat. Android phones can use that same 10W charger to its full potential, so always check the specifications for your model.
The influence of cases on wireless charging
Your case can make or break your charging experience. Thin plastic or silicone cases up to 3mm thick usually don't pose a problem. But be aware of these pitfalls:
- Metal elements : credit card holders, magnetic plates for car holders or metal decorations completely block the charging signal
- Thick protective cases : Rugged cases thicker than 5mm can make the distance between coils too large
- Wallet cases : Cards with chips or magnetic strips can be damaged by the magnetic field
Always test your case's compatibility first. If your phone gets warm but doesn't charge, something in the case is probably blocking the signal.
Common problems and solutions
Phone charges slowly or stops charging
This often happens due to overheating. Wireless charging generates more heat than wired charging. Your iPhone protects itself by slowing down or stopping charging at high temperatures. Solution: remove the case, use a charger with a fan, or charge in a cool place.
Phone slides off the charger
Smooth surfaces and vibrations from notifications are the culprits. Choose a charger with a rubber or silicone surface. For upright chargers, a lip on the bottom helps. MagSafe completely solves this problem with its magnetic attachment.
Charger makes noise
A faint humming sound is normal—this is the coils working. A loud beeping sound indicates a defect or incompatibility. Stop use immediately and replace the charger.
Wireless vs. wired charging
Both methods have their place. Wired charging remains faster—up to 27W for newer iPhones versus a maximum of 15W wireless. It's also more efficient: while wired charging is about 85% efficient, wireless charging is 60-70%. This wasted energy becomes heat.
But wireless trumps convenience. No fumbling with cables in the dark. No wear and tear on the charging port. And with multiple chargers throughout the house, you can put your phone anywhere for a quick charge in between.
Tips for optimal wireless charging
- Center your iPhone properly on the charger - if in doubt, lift and place it back down
- Use the original adapter or at least 18W for fast charging
- Remove metal objects from the charger
- Turn on airplane mode for 10-15% faster charging
- Do not charge in direct sunlight or hot areas.
- Regularly clean the surface of dust and dirt
Future of wireless charging
Technology is constantly evolving. Qi2, the new standard, brings MagSafe-like magnetic alignment to all brands, making 15W charging universally available. Longer term, manufacturers are working on remote charging—your phone charges as soon as you enter a room. This technology is still years away from consumer products, but the first prototypes already exist.
For now, the choice remains between convenience and speed. With the right charger for your needs and a little attention to detail, wireless charging becomes a seamless experience you won't want to miss.
Conclusion: find the charger that suits you
Wireless charging for your iPhone is all about finding the right balance between your daily routine and the available technology. A MagSafe charger is ideal for speed and reliability, while a simple charging pad is sufficient if you primarily charge overnight. Pay attention to the details—from wattage to case thickness—and you'll avoid frustration.
Whether you choose a separate charger or go straight for a complete refurbished iPhone including accessories, think carefully about where and when you charge most often. You'll then easily find the solution that suits you best.
