New iPhones are expected to get fully charged in about an hour or so from the moment it’s plugged into the charger. Nonetheless, there are several factors that can slow down the charging process and you will just realize that your iPhone is charging very slowly. Read on to find out why this happens and how to fix the problem on your end.

Why is an iPhone charging very slow

Many cases of charging problems are attributed to a defective charger, charging port or charging cable in use. But contrary to the common thoughts, most charging problems on an iPhone are due to software-related factors including erratic apps and corrupt charging system on the phone. And these can be triggered when a new update is installed and that update contains some bug.

There are also other cases wherein slow charging is directly inflicted by a damaged battery on the phone. This is usually transpiring on earlier devices due to wear and tear.

Troubleshooting iPhone charging very slow from an iOS update

Before troubleshooting, check both ends of your charging cable to ensure that there’s no damage. Also check the charging port on your iPhone and make sure that nothing is clogged or stuck inside. Also make sure that you’re charging from an outlet (main power source).

Charging from portable sources like a computer’s USB port, power banks, and car chargers takes longer than when charging from the main outlet because the output current from portable chargers is lower than that from the main source.

If you have complied with all these charging requisites and yet your iPhone is still charging very slow after the update, try these methods to rule out software-related culprits.

First solution: Reboot your iPhone (force restart)

There may be some rogue apps that are left running on your iPhone and they are slowing down the charging process. Apps that remained open during the software update installation are usually the ones that ended up in this state. And this is when you need to quit these apps. To get that done, simply force restart your iPhone.

On an iPhone 8, 8 Plus and later models, a force restart is carried out through these steps:

  1. Press and quickly release the Volume Up button.
  2. Then press and quickly release the Volume Down button.
  3. Finally, press and hold the Side/Power button until the Apple logo appears.
  4. Release the Side/Power button then.

On an iPhone 7 or 7 Plus, follow these steps to force restart:

  1. Press and hold both the Volume Down button and Power button for a few seconds.
  2. Release both buttons when the Apple logo appears.

On an iPhone 6s, 6s Plus and iPhone SE, a force restart is done this way:

  1. Press and hold both the Power button and Home button for a few seconds.
  2. Then release both buttons when the Apple logo appears.

Performing a force restart is only applicable if your iPhone still has sufficient battery life to power up. It abruptly ends all running apps and services that have gone rogue from the recent update. The entire process does not affect any saved data on the internal memory, hence creating backups beforehand won’t be necessary.

Second solution: Force restart while charging

Another effective solution you can try is doing a force restart while your iPhone is charging. This is applicable if your iPhone doesn’t have sufficient battery life to finish the reboot sequence. The positive effect is similar to that of a mere force restart. So here’s what you should do then:

  1. Plug your iPhone into its charger.
  2. Give it several minutes to recharge and then perform a force restart.
  3. Just refer to the above steps on how to force restart your iPhone.

Any corrupted background apps and services should be cleared out in the process and the adverse symptoms they have inflicted are likewise remedied.

Third solution: Update all your apps

This is another way to address post-update slow charging problem on an iPhone that’s attributed to glitching third-party apps. Apps that are ended up acting up from an update are those that aren’t up to date. This usually happens because they’re no longer able to meet the minimum system requirements and thus couldn’t get to run as expected.

update all apps to fix slow charging problem on iPhone after ios 13.3

If your iPhone still has enough power and has a stable internet access, follow these steps to check and install pending app updates via App Store:

  1. From the Home screen, tap App Store. Doing so will launch the app.
  2. Scroll down to the bottom of the screen then tap on Today.
  3. Tap on the User Profile icon, on the upper-right corner of the screen to load up your account details.
  4. Scroll down to the Available Updates section to view any pending app updates.
  5. Tap Update All to simultaneously install all pending app updates on your device.

When all apps are finished updating, reboot your iPhone to save and apply the recent software changes.

Fourth solution: Reset all settings

Settings that aren’t properly configured such as unused network or location features that are constantly enabled on the phone are also among the possible culprits. Thus, they must also be eliminated. To do so, just reset all settings on your iPhone to clear out any misconfigured system settings and then restore the default system preferences.

You don’t need to back up critical data on your iPhone because this reset doesn’t delete any of them. Just follow these steps to proceed:

  1. From the Home screen, tap Settings.
  2. Select General.
  3. Scroll down to and tap Reset.
  4. Select the option to Reset all settings.
  5. Enter your passcode if prompted to continue.
  6. Then tap Reset all settings again to confirm that you want to reset your iPhone’s system settings to defaults.

When the reset is finished, your phone reboots automatically and then restores the default system preferences. By then you can start re-enabling only the features that you need to use on your device.

Fifth solution: Erase your iPhone and restore its factory default settings

In some cases, slow charging issues may persist because the underlying cause is too complex that none of the initial procedures can rectify. To deal with these types of problems, performing advanced solutions like a factory reset is usually needed. Just be sure to back up all important files you saved on your iPhone storage to prevent losing them permanently.

Note that a factory reset deletes all your iPhone data and then restores the factory defaults. Any complex system errors including post-update iOS bugs that caused slow charging problem will also be eliminated.

A faster way to factory reset a responsive iPhone is through settings. And here’s how it’s done:

  1. From the Home screen, tap Settings.
  2. Select General.
  3. Scroll down to and then tap Reset.
  4. Tap the option to Erase all content and settings.
  5. If prompted, enter your passcode to proceed.
  6. Then tap the option to confirm that you want to erase and restore factory default settings.

An alternative way to factory reset is using iTunes or Finder app on the computer. This is usually needed if the iPhone is frozen or not responding.

Last resort: Restore your iPhone in iTunes

If all else failed to fix the problem, restoring the iPhone from a previous iOS backup can be considered among the last options. This is often needed if the problem is caused by a stubborn iOS bug that requires a dedicated fix patch.

If possible, back up all important files from your iPhone to your computer beforehand because they will all be wiped out when restoring.

Once you’re all set, open up the Finder or iTunes app on your computer then connect your iPhone using the original USB or Lightning cable. When your device is connected, refer these steps to enter recovery mode.

On iPhone 8 or later model:

  • Press and quickly release the Volume Up button.
  • Then press and quickly release the Volume Down button.
  • Finally, press and hold the Side/Power button until the Recovery Mode screen (Connect to iTunes) screen appears.

On iPhone 7 and 7 Plus:

  • Press and hold the Power/Top button and Volume Down buttons simultaneously.
  • Release both buttons when the Recovery Mode screen (Connect to iTunes) screen appears.

On iPhone 6s, 6s Plus, and iPhone SE:

  • Press and hold both the Home button and Power buttons for a few seconds.
  • Release both buttons when the Recovery Mode screen (Connect to iTunes) screen appears.

After successfully entering recovery mode, select your iPhone by clicking on its icon that appears on the computer and then click Update or Restore when prompted.

To reinstall the software without erasing your iPhone data, select Update. Otherwise, click Restore to erase your iPhone data and restore from a previous iOS backup.

If your iPhone supports fast charging, try using an alternative fast charger that’s compatible with  your device and see if that speeds up charging.
