About the battery going down when charging your iPhone. When you charge your iPhone, you expect its battery percentage to increase.
It will be a frustrating experience when your iPhone battery percentage goes down when charging.
But there are many reasons why this can happen, and in most instances, there are solutions you can use to fix this problem.
This article discusses the seven reasons, along with fixes to the problem of the battery going down when charging your iPhone.
Use MFI-Certified adapters and cables.
Using an uncertified cable or charger to charge your iPhone can damage the battery because it drains while charging.
Therefore, we at Cloom always recommend using the original Apple accessories, including chargers that come with the iPhone.
However, Apple no longer includes a battery charger with the iPhone. So, you will need to buy a charger or adapter separately.
For instance, you can buy an official Apple charging adapter or Made for iPhone (MFI) certified wall adapter.
We also recommend getting an excellent lighting cable if you are not using an original Apple charger.

Use a fast-charging adapter.
Apple used to bundle only a 5W battery charger with most old iPhones, which is a very low wattage based on today’s rating and standard.
For instance, one of the core reasons your iPhone battery goes down when charging is the inadequate or low power supply to the iPhone.
Therefore, we recommend getting a 20W or higher power (fast-charging) charger or adapter to charge your iPhone if you have one of the old 5W battery chargers.

Try connecting the charger/adapter to a different wall outlet
As mentioned earlier, one of the main reasons your iPhone’s battery goes down when charging is the low or inadequate power supply to the iPhone.
The major cause is either of the following;
- Using an adapter or battery charger with a low output voltage.
- Faulty wall outlet.
There can also be an electric power supply or wiring issue on a particular switchboard.
Therefore, we recommend connecting your iPhone battery charger or adapter to a different wall outlet and seeing if it fixes the problem.
Disable the “optimized charging” feature.
Keeping your iPhone connected to the power source for extended intervals can damage its battery health over some time.
So iPhone has an “optimized charging” feature that allows it to charge at a slower pace when connected to the power source overnight.
For instance, when “optimized charging” is enabled, the power going through the iPhone’s battery is limited once it hits a certain charge percentage.
Although this function can work fine, it can cause the battery to drain while charging your iPhone.
However, you can disable this feature temporarily by following these steps;
- Open the iPhone’s settings app and scroll down to the battery section.
- Click on “Battery Health.”
- Toggle off the “Optimized Battery Charging” button.
Doing this will allow your iPhone battery to charge normally until it reaches 100%.
However, disabling the “optimized charging” feature comes with a huge risk if you charge your iPhone battery for an extended period or overnight.
For instance, it can cause an issue with your iPhone battery’s health in the long run.
Do not perform heavy or intense tasks while charging
We highly recommend not using your iPhone when it is charging. You should charge it first and avoid using resource-heavy features, apps, and tools.
For example, running resource-intense tasks, such as video calls and gaming, while charging your iPhone will generate more heat, stopping your battery from charging normally.
Therefore, you should plug the battery charger into your iPhone and allow it to charge for a while (until complete) before using it.
Close any apps running in your iPhone’s background
The charging speed of your iPhone’s battery can be slower when tasks and apps are running in the background.
That may even cause your iPhone battery to drain when connected to a charger.
However, you can fix this by clearing or closing all your iPhone’s background apps and tasks.
Therefore, check the app switcher to see all the apps running in the background and close and clear them.
Once you have cleared all apps and tasks running in your iPhone’s background, reboot the iPhone, connect it to the battery charger, and check if the issue is fixed.
Check your iPhone’s battery health to see if it requires a replacement.
With Apple, you can view your iPhone’s battery health. For instance, iPhone’s battery is generally considered excellent if over 75%.
However, a battery below 75% shows it is old and not functioning correctly, thus causing it to drain while charging.
Therefore, we recommend replacing your iPhone battery if its health is low.
For instance, your iPhone will have a new battery that charges normally and works better daily.
You can check the iPhone’s battery health by following these steps;
- Navigate to iPhone’s Settings app and scroll to the “Battery section.”
- Locate and click on “Battery Health.’
Doing this will show you information about your battery insights.
For instance, if the battery capacity is so low, you will see a message that your iPhone’s battery health has degraded.
Therefore, you need to replace it.
Conclusion
Battery going down (draining) while charging an iPhone can be a common problem for iPhone users.
However, there are multiple effective methods to fix this issue.
So, use these seven solutions to resolve the issue on your iPhone’s battery and charge it normally.
