Phone’s battery draining while charging.

phones battery draining while charging

Is your phone’s battery draining while charging? The following are some of the reasons why your phone’s battery may be draining even when it is charging:

The battery in your phone is old or broken.

A worn-out or broken battery is the most common cause of your battery % dropping while charging. A lithium-ion battery is used in most phones, and it has a limited lifespan. Any lithium-ion battery has a lifetime of two to three years.

Thus, if your gadget is more than two to three years old, or if you are using a Li-ion battery that has already outlived its useful life, its functioning and ability to be recharged will be severely limited. As a result, if your phone battery is old or worn out, it may discharge while charging.

Another thing to think about is whether your phone battery was recently damaged when it started draining while charging. If you leave your phone in the sun or on a hot surface for an extended period, the battery in your phone may be badly damaged. Damage might be caused by a variety of factors. As a result, a damaged phone battery may cause the phone’s battery % to drop.

There are too many programs running in the background.

Your phone will charge at a much slower rate than usual if you have too many apps running in the background. The same is true if you’re charging your phone while using it. When there are too many apps operating in the background, the battery’s ability to charge quickly is severely harmed. Having too many running apps in the background on a phone with a good battery will, in most cases, cause the phone to charge at a slower rate. When it comes to phones older than two to three years (with a worn-out battery), using too many applications in the background will not only slow down charging but will also deplete the battery’s health.

A faulty or insufficiently powerful charger or charging wire

A faulty charger or charging cord is another typical cause of the battery % dropping. A faulty charging cable or charger will be unable to charge the phone adequately (or at all), resulting in the problem that has prompted you to read this page right now.

Although most of the time it is a faulty charging cable that causes the phone battery to drain when charging, it is possible that the charger is to blame. If you’re using an ineffective or malfunctioning charger, your device’s battery % is likely to suffer as a result. When we say “non-powerful charger,” we’re referring to a charger that has a lesser rating than your device’s battery rating and, as a result, is unable to recharge the phone’s battery health.

The presence of foreign particles in the port

A loose connection between the phone and the data cord might be caused by foreign particles in the charging port. This implies that the phone may continue to lose connection with the data cord (and, eventually, the charger), preventing good battery health replenishing.


Due to a poor connection between the phone and the data cable caused by foreign items in the port, the charger’s output current may drop and fail to offset the phone’s power consumption. As a result, the battery % will decrease during charging.

Failure to use a genuine or approved charging cord or charger

When you use an unofficial charging cable or charger, the output current is insufficient to balance off your device’s power usage, resulting in a power drain. Although this isn’t always the case when the charger’s rating matches your device’s battery rating, most inexpensive and local charging cables or chargers aren’t compatible with your device’s battery rating.

Another thing to keep in mind is that low-quality chargers and charging cords might have a variety of manufacturing flaws. Apart from causing your battery percentage to drop even when charging, this might influence the overall longevity of your phone’s battery.

Charging through computer/laptop or automobile

The USB port on a computer can only supply a limited amount of power: 500 mA for USB 3.0 ports and 900 mA for USB 1.0 ports. Dedicated wall chargers are typically more powerful than PC/laptop chargers or even vehicle chargers.

Consider the scenario of a phone that consumes 200 mA. The wall charger has 800mA remaining, which is the same as the USB port’s remaining 300mA. Nowadays, a common phone has a battery capacity of around 1500 mAh (milliampere-hour).

If a current of 1500 mA is utilized, the battery will be charged in one hour. The same battery might be charged in five hours through the port and then in around an hour using a wall charger.

The phone is in “slow charge mode,” which is slower than regular charging since the computer’s amperage and voltage are lower than usual. As a result, the computer or laptop charges more slowly.

As a result, if you have an older phone with poor battery life, charging through a PC or laptop would be much slower. This might be one of the reasons why your phone’s battery % continues to decrease even when it is charging.

You’ve got an Internet connection on your device.

When your phone is linked to a mobile data or wi-fi network, it can quickly drain your battery. Your favorite applications will send you alerts all the time. If you have a device that is three years old or older and does not support fast charging, you may have difficulties such as the battery % dropping when charging as a result of this.

What should you do if your phone’s battery % continues dropping while it’s charging?

You can attempt several ways to cure the problem depending on the cause of the problem, such as the phone’s battery draining while charging.

Fix 1: Limit the number of programs that run in the background.

Limiting the number of background apps on your smartphone can be a good method to solve the problem if your phone is old and you have a lot of them crammed into it, draining the battery. The Overview button may be used to clear background programs.

The “Overview Button” is located to the left/right of your “Home/Menu button,” however on some phones, you’ll need to utilize gestures for system navigation, such as removing background apps to save power consumption.

Fix 2: Enable the power-saving mode.

Power Saving Mode, as the name implies, prevents your battery from rapidly dwindling by restricting data usage, background programs, and so on. As a result, you can try turning on Power Saver mode before charging your phone to see if the problem remains.

Fix 3: Disconnect from WiFi and/or mobile data.

If your phone’s battery % is dropping while charging due to keeping connected to the internet, the simplest solution is to turn off WiFi or Mobile Data. Toggle down the notifications panel and choose the Mobile Data or WiFi icon.

Fix 4: Replace the charger or charging cord.

Replace the faulty charging cord or charger with a new or fully functional one. If your charger works great but isn’t compatible with your phone’s battery rating, purchase a new, more powerful charger and double-check the rating first.

Fix 5: Clean the charging port

Blow air into your device’s charging port to remove any debris that may have become caught within, producing a loose connection between the device and the charger (and thus the overall problem).

You may also use a toothpick to remove debris from the charging port, but be careful not to push too hard or your phone’s internal components may be damaged.

 Fix 6: Use a charging cord or charger that is certified or original.

Only use approved chargers and charging cords from the maker of your gadget or a respected firm in the niche.

This verifies that both the charger and the charging cord are compatible with your smartphone, allowing for effective phone charging.

Fix 7: Change to a more reliable power source.

If you’re charging your phone with a USB cord from a PC or laptop, we recommend switching to a more reliable power source.

In comparison to a laptop or PC, a wall charger may give far more power to the charger and, eventually, the device for effective and speedy charging.

Fix 8: To replace or repair your phone’s battery.

If none of the other options have worked, the last recourse is to get your phone battery serviced or replaced. If your battery is far beyond its useful life, it’s time to get it changed by a manufacturer-authorized repair center.

If your new battery is damaged, you may take it to an authorized service facility, where they will fix or replace it depending on the frequency of the damage.

5 Myths that Affect the Health of Your Phone’s Battery

Here are five common misconceptions about battery health that might shorten its lifespan:

Myth 1: You need fully discharge your battery before charging it.

You are not only not compelled to do so, but you should also refrain from doing so. The charge cycle refers to the number of times a battery may be charged to 100% capacity. Most phones have a charge cycle limit after which the battery life begins to deteriorate. It’s usually 400 to 500 charge cycles with iOS devices. If you let your battery drain entirely every day, it will last 500 days. You’ll have enough time to recharge it if you charge it before it runs out of juice.

However, there is one reason to let your battery entirely discharged: if the battery symbol shows a positive charge, the battery will need to be reprogrammed or re-calibrated. To repair the problem, it’s best to completely drain it and then recharge it.

Myth 2: Your phone should not be charged overnight.

Charging your battery at night is entirely acceptable. It’s the most effective way to ensure that your battery is fully charged so that you can go through the day.

This superstition dates back to the days when phones utilized nickel-ion batteries, and if you didn’t allow the charge entirely discharge, the part that wasn’t used would be forgotten.

Thanks to the adoption of non-memory-losing batteries, today’s phones offer sophisticated power management. You won’t have to worry about overcharging because the phone will stop charging when it reaches 100%.

Myth 3: If my phone is charging, I shouldn’t use it.

Using your phone while it’s charging carries a low risk. This misconception arose from concerns about battery overheating. Li-ion batteries can be harmful if they have a manufacturing flaw, although the risks are minimal. If your phone gets too hot when charging, you should turn off the charger. Counterfeit chargers are a problem to be aware of. You risk damaging your phone if you don’t use a cord recommended by the manufacturer. You must get approved and branded chargers to charge your phone more effectively.

If the screen is on or apps are operating in the background, your phone will charge at half the speed. If you want your phone to charge faster, put it in airplane mode. Using a power outlet to charge your phone is always faster than using your vehicle or computer charger.

Myth #4: If I charge my battery properly, it will last forever.

We must understand that our batteries must be replaced because they are the weakest portion of our phone and can only hold a charge for a short time. They’re also short-lived. 

Because batteries lose capacity as they age, you may only be able to use 60% of your phone’s capacity if you still have enough life remaining. If your phone’s battery is wearing out too quickly, try changing it to extend its life.

Li-ion batteries don’t like it when their charge is low or high. It is thought that keeping your phone’s battery below 80% for most of the time is the greatest approach to extending its life.

Myth #5: Killing applications conserves energy.

This isn’t correct, and it’s also poor counsel. You use more resources and power if you terminate and restart programs than if you leave them running in the background.
