Why Is My iPhone Not Charging Fast? Here’s What’s Up
Ugh. The low battery warning. Again. This time, I knew I’d be scrambling. My iPhone, for some reason, just refused to charge at a decent pace. I plugged it in overnight, expecting a full 100%, and woke up to… 38%. Seriously?
It’s infuriating when your iPhone stubbornly refuses to cooperate when you need it most. That sinking feeling as you watch the percentage slowly creep up. What in the world is happening?
Many articles drone on about chargers and cables, but that’s not always the core problem. The question on everyone’s mind is truly: why is my iphone not charging fast? Let’s dig in.
It turns out, there are several sneaky culprits behind this charging slowdown, and some of them are pretty surprising.
The Cable’s the Culprit (sometimes)
First things first: the cable. Sounds simple, right? Wrong. I’ve wasted a small fortune on cheap charging cables, assuming they were all created equal. They are not. I learned this the hard way during a trip to Yosemite. My iPhone was my lifeline for photos and GPS, and my $8 cable from the gas station was a total dud. It trickled power so slowly, I might as well have been using a hand crank.
It’s easy to assume all Lightning cables are the same. I did. But after that experience, I started paying attention. You’ll quickly see that not all cables are created equal. Some are designed for data transfer, some for charging, and others are just plain awful. The worst part? They all *look* identical.
Then, I spent around $20 on a good quality cable. The difference was immediately noticeable. My iPhone charged significantly faster, and the cable felt far more robust. The plastic was thicker, the connectors felt more secure. It was a completely different experience.
So, check your cable. Look for a cable that is certified by the MFi (Made for iPhone) program. These cables have been tested and approved by Apple, and you can trust that they will deliver the correct amount of power. Also, inspect the cable for any damage. Fraying or exposed wires are a charging disaster waiting to happen. The solution is easy: replace the cable.
The Power Adapter’s Power Struggle
Next up: the power adapter. This is where things get interesting, because the advice you hear everywhere is often wrong. Everyone tells you to use the original adapter that came with your iPhone. I disagree, and here is why: the included adapter is often underpowered for modern iPhones. Apple still ships a wimpy 5W adapter with their phones, and that adapter is *not* going to give you fast charging. Consider the design comparison to an automotive analogy: it’s like using a tiny engine to haul a large trailer. Sure, it *works*, but it’s slow, and it puts extra strain on everything.
However, newer iPhones support fast charging, which means they can draw more power from the adapter. If you want fast charging, you need a power adapter that supports it. Most iPhones can handle up to 20W of power. This is where you actually see the speed boost. The difference between 5W and 20W is massive. It can be the difference between a charging time of four hours and a charging time of one hour. (See Also: Can You Charge Iphone 13 With Lightning Cable )
The solution? Ditch the old adapter. Get a 20W or higher power adapter. You’ll be amazed at the difference. I would say this is the single best and most effective upgrade you can make.
Is Your iPhone Actually *fast* Charging?
Here’s a tip that nobody shares: you need to *confirm* that your iPhone is fast charging. Even if you have the right cable and adapter, the phone itself can be the bottleneck. Believe it or not, I didn’t even know this was a thing until my fifth attempt to figure out why my phone was still charging so slowly. There’s a setting that may be turned on that will impact charging speed.
To check, plug your iPhone into a fast charger. Then, go to Settings > Battery > Battery Health & Charging. If “Optimized Battery Charging” is turned on, that can slow down the process to protect your battery’s lifespan. You can turn this off if you need a quick charge, but keep in mind that doing so could slightly reduce the longevity of your battery in the long run. There’s a trade-off here, similar to how a race car driver balances speed and tire wear.
Also, check for any apps that might be draining your battery while charging. Power-hungry apps like games and video streaming services can slow down the charging process. Close these apps before plugging in your phone. Also, make sure that your iPhone isn’t in airplane mode or low power mode. Both of these settings will affect charging speed.
Finally, ensure your iPhone is not too hot. Apple’s guidelines state that iPhones should be used in ambient temperatures between 32° to 95° F (0° to 35° C). Extreme temperatures can slow down charging to protect the battery. If your iPhone is hot to the touch, move it to a cooler location.
Another thing to keep in mind is the iPhone’s age. An older battery will charge more slowly than a new one. After a few years, the battery’s capacity degrades, which impacts charging speed. If your iPhone is several years old, consider getting the battery replaced or upgrading to a newer model.
The Software Side of Things
Sometimes, the slowdown isn’t about hardware. Software can play a role, too. An outdated version of iOS, for instance, could be causing charging issues. Updating to the latest version of iOS can often resolve these types of glitches, especially since Apple releases updates to address battery issues. It’s like updating the software on your car’s engine control unit — it can optimize performance.
Here’s what you need to do: Go to Settings > General > Software Update. If there’s an update available, download and install it. This is a very easy step, but it’s often overlooked. It’s something you should do every month or so, as needed. Software updates often include behind-the-scenes improvements that can affect charging speed.
Also, consider the apps you have installed. Some apps are notorious battery hogs. Check your battery usage in Settings > Battery to see which apps are draining the most power. If you find a particularly demanding app, consider closing it while charging or deleting it altogether if you don’t use it often. These tiny little actions can help.

Finally, there’s always the dreaded “reset all settings.” This wipes your iPhone’s settings back to factory default, but it doesn’t delete your data. It’s like giving your phone a clean slate. Go to Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings. This is a last-resort option, but it can sometimes clear up any underlying software issues that are slowing down charging. Just be sure to back up your iPhone before doing this, just in case.
Wireless Charging: The Lazy Way (but Is It Fast?)
Wireless charging is convenient, no question. Place your phone on a pad, and it starts charging. Easy. However, wireless charging is almost always slower than wired charging. I found this out while experimenting with several wireless chargers, including ones from well-known brands. I spent roughly $150 on three different wireless chargers, including a MagSafe charger from Apple, and none of them charged my iPhone as quickly as a cable. The difference, in my experience, was easily 30-45 minutes to get to a full charge.
There are some exceptions, such as MagSafe chargers, which can charge at up to 15W. This is faster than standard wireless chargers, but still slower than wired charging. It’s like the difference between a leisurely bike ride and driving in a car — both get you where you need to go, but one is clearly faster. Wireless charging is a trade-off. It prioritizes convenience over speed. According to research conducted by the American Consumer Institute, wireless charging on iPhones typically delivers about half the charging speed compared to a wired connection.
If speed is your priority, stick with a cable. If convenience is more important, wireless charging is fine, just be aware that it’ll take longer. You must decide which is a priority for you.
