The batteries in iPhones are typically quite strong. It is concerning, though, when a consumer reports that their iPhone’s battery is draining while it is being charged. As a result, people frequently ask us how to solve it. These suggestions, advice, and instructions will help you fix your iPhone’s battery draining while it is charging.
Causes of Depleting Phone Battery
There are several reasons why this might be happening. Typically, this indicates that although your phone detects a cable plugged in, no power is being sent to the phone battery. Another possibility is that the phone battery is refusing to accept a charge. The causes could be anything from a defective iPhone to a charger issue to a charging port issue.
1. Subboard / Charging port damage
The worst-case scenario for why your battery discharges when charging is that the sub-board is defective. Because the sub-board is attached to the charging port, charging problems, including overcharging, overheating, and voltage fluctuation, might harm the sub-board.
Liquid damage can occasionally lead to a damaged subboard (charging port), especially if the liquid seeps under the LCD panel. Take your phone to a mobile phone specialist for iPhone repair if this is the cause of your phone’s battery draining while it is charging.
2. Bad charger / Cable
Your phone’s battery may occasionally drain while it is being charged if you use the wrong charger and cord. Usually, this should stop if you go back to the suggested cable and charger. You can verify that you are utilizing the charger that the manufacturer recommends.
Perhaps you had to use an impromptu charger while traveling to keep your gadget powered. If you do this frequently, your phone’s battery life may decrease while it is being charged. It harms your phone if the charger generates more energy than the battery requires.
Phone is overheating
When charging your phone, you might notice that the battery is depleting if it is already overheated. The phone may end up not charging, or the battery may be reduced because an overheated device cannot accept much battery charge.
Before charging the phone, turn it off and give it some time to cool down. If the issue is caused by overheating, this should fix it.
How To Fix iPhone Battery Draining While Charging
1. Use certified cables and chargers
Use only cables and chargers designed specifically for iPhones. The best option is to use the original iPhone accessories. By doing this, you can be sure that this isn’t the cause of your iPhone’s battery draining while it’s charging.
Purchase a wall charger designed exclusively for iPhone if you no longer have the original accessories or a newer iPhone without one. Additionally, consider using a cable if the iPhone battery is depleting while charging wirelessly.
2. If your iPhone battery drains during charging, check the power supply.
An iPhone can run out of juice if it is not connected to a strong enough power source.
Consider purchasing an iPhone-specific fast or powerful charger. Most of these are functional 20W USB-C fast chargers, although 65W variants are also available.
3. Try Connecting Your Charger To A Different Wall Outlet
If you read the last sentence of the previous point, we mentioned that a low power supply to the iPhone causes its battery to drain even when it is plugged into a charger. For example, this could be caused by an adapter with a low output rating. An unreliable wall outlet is an alternate possibility. There could be a problem with the wiring or the power supply on a certain switchboard. So, connect your charger to another power outlet and see if that solves the problem.
4. Disable Optimized Charging
Apple included a handy little function called Optimized Charging to the iPhone to maintain battery health and prevent overcharging. It uses on-device characteristics to calculate when you typically plug in your iPhone to the charger and when you need it to be fully charged.
This is useful, particularly for those who plug their iPhones in overnight to charge them. Using optimized charging, your iPhone is charged swiftly up to 80% of the way and then slowly (sometimes called trickle charging) until it reaches 100%. Even when your iPhone is linked to a charger, this feature occasionally behaves erratically and prevents it from charging, which drains the battery. Here’s how to momentarily turn it off.
Step 1: Launch your iPhone’s Settings app and go to the Battery section.
Step 2: Tap Battery Health.
Step 3: Disable Optimized Battery Charging by pulling the lever.
Your iPhone will then continue to charge regularly to 100%. If you charge your iPhone overnight or for a long time, deactivating Optimized Battery Charging carries a significant risk that it could eventually harm the battery in your iPhone.
5. Check Battery Health To See If It Needs A Replacement
On your iPhone, Apple allows you to check the battery’s condition. The battery health of your iPhone is often regarded as good if it is above 75%. If it falls below that, it means that the battery in your iPhone has aged and is no longer operating as it should. It could not be charging correctly due to this.
If your iPhone’s battery life is low, you should install a new battery. Therefore, your iPhone will receive a new battery that will charge correctly and perform better during normal use.
