Reasons Behind Draining/Decreasing Battery While Charging iPhone

When you charge your iPhone, the percentage of the battery should increase. But occasionally, you might find that the battery level percentage is falling rather than rising.

Earlier, we briefly mentioned a few reasons for the issue. However, there can be many other reasons as well. These include the following:

• Faulty charging port.
• Malfunctioning adapter or charging cable.
• Using a non-Apple-certified charger.
• Overheating the iPhone.
• Using a computer to charge rather than a power outlet.
• Weak AC power supply.
• Some battery-draining application is running in the background.
• Hardware problems.
• Battery issue.
• Failing drivers or upgrades.
• The optimized battery charging option is disabled.

How to fix the decreasing battery while charging the iPhone?

The aforementioned list of causes might seem hard to solve but there are some easy fixes as well. Hopefully, by trying these below mentioned simple fixes, you will be able to overcome this difficult situation.

Solution 1: Check the charging port

In most cases, a defective charging port is likely to be the most common thing that causes battery draining even while charging. It basically prevents the device from recharging correctly.

In such a case, check the charging port for noticeable wear or damage to resolve this problem. It might need to be replaced if you see any damage, such as bent pins or cracks. Depending on the model, this might cost you anywhere from $50 to $150.

However, even if the port appears to be in good condition, it still might contain some dust. You can clean it using a soft toothbrush or toothpick. This might fix the battery drain problem.

Solution 2: Use an Apple-verified charger and cable

If the problem persists even after trying the previous solution, it could be due to using an unverified charger and cable.

Apple has long advised customers to use MFI-approved cables and chargers. MFI means “Made for iPhone/iPad/Pod.” It is an Apple-created licensing arrangement.

Accessories that are MFI approved are made to power any device with the appropriate amount of power and won’t harm the battery.

If you replace your non-certified charger and cord with an MFI-certified one, your problem could be resolved. Nonetheless, go on to the next one if this problem remains.

Solution 3: Check if your iPhone is overheating

If your iPhone overheats while charging, it could lead to a drop in battery level. However, due to the advanced technology of Apple devices, this overheating issue rarely has a noticeable effect.

But, if you feel that your phone is getting too hot when charging, consider taking the case off. Since cases might trap heat and prevent your iPhone from properly dissipating it, causing it to overheat.

Also, keep your iPhone away from hot environments or direct sunlight while charging.

Solution 4: Use the AC wall power outlet instead of the PC’s USB port.

Sometimes, your iPhone’s battery level decreases if you charge it with your PC or laptop’s USB port. These ports can not provide sufficient power to charge the device properly.

So, rather than using a PC’s USB port, it is advised to utilize a power outlet. But, if you are compelled to use a computer’s charging connections, be sure that the USB port on your computer is supplying adequate power.

Here you can use a charge monitoring APP called “Ampere.” Connect your iPhone to another USB port if this APP shows poor “A” (ampere).

Solution 5: Fix the battery issue

Mobile phones like iPhones batteries are made with Lithium-Ion or Lithium-Polymer technology. And, they have a limited lifespan. These batteries/cells typically last 500 to 600 cycles before they lose 80% of their original capacity.

In this situation, replacing this battery with a new one is the only solution. You can replace it in an Apple Store or Apple authorized service provider. Apple charges between $49 and $99 for iPhone Battery Replacement Cost.

But, if you are on a low budget, you can also replace it on your own. This video guide might help you if you never do it before.

Solution 6: Try a different AC power outlet

It may appear strange, but a faulty AC power socket might cause this battery to decrease while charging.

Basically, every Apple charger has a minimum AC power input rate. That’s why the charging adapter can’t operate properly if the wall AC socket provides less than the minimum range.

So, if the previous method fails, try charging your iPhone from a different AC power outlet. This might solve the issue. But if the problem persists, try the following suggestion.

Solution 7: Update your iPhone to the latest version

If the battery percentage is still dropping while charging, make sure that the most recent version of iOS is installed on your iPhone.

This can occasionally address the battery level decreasing issues. To check for available updates for your iPhone, navigate to Settings > General > Software Update.

On the other hand, you can try rebooting your iPhone. It might resolve this issue. Switch off your phone and press the power key until the Apple logo displays. It may resolve any software glitches that reduce battery life.

The battery draining problem might be fixed by employing these methods. But, when none of these procedures work, you might have to take your phone to the service center.

Solution 8: Close all background running applications

If you’re still experiencing a power drain issue, one or more programs might run in the background. So, double-tap the home button to reveal the programs now operating in the background. Then, swipe up to close them.

Also, disable all the extra features like Bluetooth, mobile data, and location services while charging.

Solution 9: Fix the hardware issue

Finally, if the battery-draining issue is still present, there is undoubtedly a hardware issue with the iPhone. In this situation, you must take your iPhone to an expert mechanic or Apple-authorized service provider.

Here, we strongly advise you to go to an Apple-authorized service provider or knowledgeable technician because an untrained or inexperienced mechanic runs the risk of further harming your phone.

If your iPhone is still covered by warranty, Apple might pay for the repairs. Otherwise, depending on your region and your iPhone’s model, this repair might range from $20 to $100.
