Part 1: Why iPhone Is Slow Charging After the iOS 17 Update?

Let's start by checking the basic things. Sometimes, iPhone charging slowly after an iOS 17 update may be due to multiple apps running in the background, using your phone while charging, or charging it on a computer instead of a power outlet. Let's dig deeper if you've already ensured none of these is the issue.

Software Glitches or Bugs (iOS 17)

If you recently updated your iPhone to iOS 17 and noticed that it's charging slowly, it might be due to the new software. Remember, iOS 17 might still have some errors or problems because it's in the beta phase. That means it's not the final version that Apple officially releases. So, there could be some issues with it.

Optimized Battery Charging

With iOS 13 and later versions, Apple introduced Optimized Battery Charging. This feature helps your battery last longer by reducing the time your iPhone stays fully charged. You'll see a notification on the Lock Screen showing you when your iPhone will reach full charge.

Clean Energy Charging

Check if your iPhone has Clean Energy Charging enabled. This feature helps the environment by using clean energy sources but can also cause slow charging. If clean energy is not readily available, your iPhone might wait until it's accessible, which can slow down the charging process.

Faulty iPhone Battery

Sometimes, the problem is with the iPhone's battery itself. If it's old or damaged, it might not charge as quickly as before.

Dirty iPhone Charging Port

Dust and dirt can accumulate in the charging port over time, making it harder for the charging cable to connect properly.

Damaged Charging Cable

Finally, it's crucial to check your charging cable. If it's frayed or damaged, it won't work correctly, and your iPhone will charge slowly or might not charge at all.

Part 2: What To Do First if Your iPhone Is Charging Slowly After iOS 17 Update?

If your iPhone is charging slowly after updating to iOS 17, don't worry, there are some things you can do to fix it. Let's go through the first things you might want to do.

Check the Charging Cable and USB Adapter for Damage

The first thing to do when your iPhone is charging slowly after updating to iOS 17 is to check your charging cable and USB adapter. Look for any signs of damage, like the broken cable or the bent prongs on the adapter. If it is, you can get a new one for your iPhone.

Also, check that everything is connected securely. Also, plug the USB charging cable into a wall power outlet, not the computer, which may charge your iPhone faster. If it's still slow, try a different outlet.

Turn Off Optimize Battery Charging Feature and Clean Energy Charging

To turn off this feature, go to your iPhone's Settings > Battery > Battery Health & Charging. Next, turn off the Optimize Battery Charging and Clean Energy Charging toggle switch.

Check Your Battery Health

If your iPhone's battery is old or damaged, it might not charge well. You can check your battery health in the same settings as the other two above. If it's below 80%, consider getting the battery replaced.

Clean the Charging Port

If you are unsure whether your iPhone is slowly charging after updating to iOS 17 because of the settings above, look inside its charging port. Sometimes, the charging port on your iPhone can get dirty or clogged with stuff. Check it out and remove any debris you see. If the charging port looks damaged, uh-oh, that might be why your iPhone is acting up. It could need some fixing.

Charge iPhone for 30 Minutes

Give your iPhone a little break. Let it charge for at least 30 minutes without using it. Sometimes, when you use your iPhone while charging, it slows down the charging process. So, let it rest for a bit.

Force Restart Your iPhone

Fix iPhone charging slow after iOS 17 update by force restarting it. Here's how: press and release the volume up button, then press and release the volume down button. Now press and hold the side button until you see the Apple logo on the iPhone screen.

Go to Apple Store

If none of the workarounds fix your iPhone charges slowly after iOS 17 issue, contact Apple Support.

Certainly, you may try all the ways mentioned above, and unfortunately, none can make a difference to your iPhone's condition. In this case, you may need to check and fix problems in the operation system. Here, Wondershare Dr.Fone – System Repair can be your final solution.

We've gathered some questions many Apple users are asking, and you might want to know the answers too! Let's dive in!

Battery health of 85% is pretty good for iPhone. Normal batteries are designed to keep about 80% of their original capacity after 500 complete charge cycles under regular conditions. As your battery gets older, it might not work as well and can affect how long it lasts on one charge. Don't worry; it's normal for batteries to age.

If you charge your iPhone daily, it might wait until you need it to reach 100%. To take care of your battery, Apple has designed software and hardware to manage charging and temperature. It keeps the battery healthy for longer. If you leave your device fully charged for a long time without using it, the battery may lose some capacity.

Extreme temperatures are not good for your iPhone's battery. Avoid exposing it to temperatures higher than 95°F (35°C). High temperatures can damage the battery capacity, and you might notice that your battery doesn't last as long on a single charge.
