How to Fix Your iPhone’s Battery Woes While Charging

Step 1: Is It the Charger or Cable?

Let’s start with the basics. Sometimes, the villain causing your battery blues might be a rogue charger or cable. Give your charging cable a good look-over. If it’s frayed or looking worse for wear, it’s time to part ways. Get yourself an authentic Apple cable or a trusted third-party one. Those cheaper knockoff cables? Yeah, they can spell trouble.

Step 2: Clear the Charging Port Clutter

Over time, your iPhone’s charging port can turn into a magnet for dust, lint, and who knows what else. All this gunk can mess up the connection, leading to charging woes. Turn off your iPhone and be gentle but thorough when cleaning the charging port. A soft brush or some compressed air can do wonders.

Step 3: Restart It!

Let’s kick it up a notch. Sometimes, all your iPhone needs is a little digital siesta. A simple restart can work wonders for minor software hiccups that might be causing battery drain during charging. 

Press and hold that power button (or the volume down button and side button for iPhone X and newer) until you see the slider. Slide it to turn off your iPhone and then power it back on after a short breather.

Step 4: Stay Up-to-Date with iOS

Remember those software updates you keep postponing? Well, they often come with fixes for annoying glitches, including charging problems. 

Head to Settings > General > Software Update and make sure your iPhone is rocking the latest iOS version. It might just solve your charging blues.

step 5: Pesky Background Apps

Here’s another sneaky culprit: apps running in the background. They can gobble up precious battery life even while you’re charging. 

To check if these little energy thieves are at play, venture into Settings > Battery. You’ll get the lowdown on which apps are being battery hogs. Shut down the unnecessary ones and see if that turbocharges your charging.

Step 6: Reset, but Don’t Panic

If you’ve tried everything and your iPhone is still acting up, consider resetting all settings. Relax, it won’t nuke your photos or messages, but it will reset your preferences. 

Head to Settings > General > Reset > Reset All Settings. Afterwards, take a few moments to set things back to your liking and see if the charging issue waves goodbye.

Step 7: Battery Calibration Time

Your iPhone’s battery might just need a little recalibration. To do this, let your iPhone run out of juice completely until it shuts down. Then, give it a full charge without any interruptions. This can help recalibrate the battery indicator and make it more accurate.

Step 8: The Last Resort: Restore

Now, here’s the nuclear option. If all else fails, you can restore your iPhone to factory settings using iTunes (for macOS Catalina and earlier) or Finder (for macOS Big Sur and later). But beware, this wipes everything clean. After restoring, set up your iPhone as if it’s brand new and keep an eagle eye on its charging behavior.


Facing a battery that’s playing hard to get while charging your iPhone is no picnic, but it’s a challenge that can be conquered with the right iPhone repair approach. Start with the easy fixes like checking your charger cable and cleaning the charging port. Then, venture into the software realm by restarting your iPhone and staying updated with iOS to potentially avoid the need for professional iPhone repair services.

Remember, use authentic accessories, and don’t go overboard with DIY fixes. If your iPhone still isn’t playing nice, don’t hesitate to reach out to the pros at Wireless Waves Repair.
