Why won’t my iPhone charge?

Why won't my iPhone charge?

You connect your iPhone or put it on a wireless charger to charge the battery, check again later and it is not charged. What happened? Many things can go wrong. Let’s take a look at some of the most common iPhone charging issues and what you can do about them.

General troubleshooting tips

An Apple Lightning USB cable

One of the most fundamental debugging techniques is called «replacement with well-known parts». Take an accessory that you think might not work, and replace it in your configuration with an identical part that is new or already known to work.

Problems uploading? Replace the old cable with a new one. If the charging process works with the new cable, the problem was the old cable.

You can replicate the process with all components of the setup, including the iPhone itself (borrowing a friend’s iPhone and seeing if it charges with the charger) and any USB power source you use. Try another wall adapter, USB hub, computer USB port, or electrical outlet.

Beyond this basic technique, here’s a closer look at other things you can try.

Restart your iPhone

Apple iPhone software is sometimes confused with loading operations due to errors or errors in its programming. Sometimes that software crashes and doesn’t work properly. The best way to temporarily resolve this issue is to restart your phone.

On iPhone X or iPhone 11 , press and hold the side button and one of the volume control buttons at the same time until the «Slide to power off» screen appears. Release the buttons and slide your finger on the screen to turn off the phone.

On iPhone 8 or earlier , press and hold the side button until the «Slide to power off» screen appears. Release the side button and slide your finger on the screen to turn off the phone.

On iPhone SE, 5 or earlier , press and hold the top button until the «Slide to power off» screen appears. Release the button and slide your finger on the screen to turn off the phone.

Swipe Apple iOS to turn it off

Once the screen turns black, press and hold the side button until you see the Apple logo in the middle of the screen.

After the phone has finished turning on, try charging the phone and see if it works.

After rebooting, it’s a good idea to see if there are any updates available for operating system It is iPhone (called iOS) which can solve the loading problem. To do this, see the step below.

Update your iPhone operating system

The software that controls charging on the iPhone may have typos. Sometimes Apple detects these errors and fixes them with updates.

There’s a problem: your iPhone’s battery needs to be 60% or higher to charge. Apple requires this, because if your battery is discharged during the update, it may damage your phone.

If you agree with battery life, here’s how to update your iPhone: Navigate to Settings> General> Software Update to see if an iOS software update is available. If so, please update, wait for the phone to restart, and then try charging again.

Check the Lightning cable

If restarting and updating your phone didn’t help, it’s time to start looking for possible hardware issues.

Apple has a special brand name for the charging connector on the bottom of the iPhone: Lightning. Take a look at its Lightning USB charging cable at both ends.

  • Are the cable connectors damaged or broken?
  • Are there exposed wires coming out of the plastic insulation anywhere in the wire?
  • Is the cable twisted or bent at a sharp angle?

If the answer is «Yes» to any of these questions, recycle the broken cable with other electronic waste and buy a new one.

When the wires inside the Lightning cable break, it interrupts the charging circuit and will prevent the iPhone from charging properly. This is a common problem with Lightning charging cables produced by Apple, which are made of a type of soft rubberized plastic that decomposes over time.

Also notice the gold contacts on the Lightning connector on the cable. Are they dirty or discolored? If so, you can rub them with a regular eraser to clean up debris. The eraser is abrasive enough to remove dirt without damaging the metal contacts. Be sure to clean any piece of eraser before inserting the connector into an iPhone for testing.

Check the iPhone Lightning connector

Pocket lint and dust often accumulate in the Lightning port on the bottom of an everyday iPhone, especially if the phone is frequently kept in a trouser pocket. Lint physically collects and locks the Lightning cable from full insertion and makes a solid connection.

You can remove lint from your iPhone’s Lightning connector with a small, non-metallic object, such as a wooden or plastic toothpick. This technique works well, but it is somewhat risky and could damage the small pins of the connector inside the iPhone. If you’re nervous about doing this, take your iPhone to an Apple repair shop.

Do not spray compressed air on the Lightning connector to remove lint. It will push dust and lint further towards the phone. Blowing dust on the phone could catch it all over the room and create blurry photos.

Check the charging adapter or USB power supply

IPhone and iPad chargers

IPhones need a certain amount of power from a USB source to charge in a reasonable amount of time (several hours). The most reliable power supply is the included wall adapter manufactured by Apple.

To be more technical, an iPhone charger must provide at least 1 amp («A» or «Amps» for short) to charge an iPhone efficiently. Many USB ports on older computers, keyboards, hubs, or chargers do not provide enough power (many provide 0.5 A or less, also known as 500 mA), so iPhones connected to these sources are they will load very slowly. If the iPhone screen is on or the iPhone is used while connected to one of these low power sources, it may not provide enough power to charge the battery.

The included charger with an iPad works well for charging an iPhone; in fact, it will charge even an iPhone faster than the original Apple charger made by Apple. This is because the iPad wall adapter outputs 2.1 amps of power, which is higher than most iPhone chargers. The electronic components inside the iPhone know how to handle the extra power, so in general, users do not have to worry about overcharging the iPhone from a USB power supply.

Check the wireless charger

All iPhones starting in 2017 (including iPhone 8 and iPhone X) support wireless charging. To use wireless charging, you must have a special wireless charging cradle or a surface designed to work with Qi wireless charging standard.

This can be a great temporary solution for charging your iPhone if you’re having trouble charging with a Lightning cable and have a wireless charger available.

To charge properly with a wireless buffer or dock, your iPhone must be centered in the middle of the charging area, which may vary by device.

If wireless charging doesn’t work, try charging with a USB cable to Lightning (see the previous sections) or another wireless charging buffer.

If all else fails

If none of the above tips help, it’s time to put on on Contact Apple Support or make an appointment for technical support at an Apple store. Good luck, I hope you know.
