In today’s tech-driven world, leaving a phone charger plugged in without a device attached seems harmless. Many of us do it out of habit, convenience, or simple forgetfulness. But according to electricians and safety experts, this common practice carries hidden risks that could damage your charger, waste energy, and even create a fire hazard.
If you’ve been doing this for years without knowing the potential dangers, don’t worry—you’re not alone. Let’s dive into why you should stop leaving chargers plugged in when not in use and what you can do instead to keep your home safe and energy-efficient.
How Chargers Work: The Science Behind the Risk
To understand why leaving your charger plugged in without a device is a bad idea, it’s important to know how chargers function.
- AC to DC Conversion – Your phone charger takes the alternating current (AC) from your wall outlet and converts it into direct current (DC), which is safe for charging your device’s battery.
- Continuous Power Draw – Even when your phone isn’t connected, the charger still draws electricity, albeit at a low level. This is known as vampire energy or phantom load—small amounts of wasted energy that add up over time.
Now, while this might seem insignificant, the long-term effects can be serious.
The Hidden Dangers of Leaving a Charger Plugged in Without a Phone
You may not notice any immediate issues, but the cumulative impact of keeping chargers plugged in all the time can be costly and even dangerous. Here’s why:

1. Fire Hazards: Overheating and Electrical Fires
One of the biggest risks of leaving chargers plugged in is the potential for overheating, which can lead to electrical fires.
- Chargers that are cheap, damaged, or low-quality are more prone to overheating when left plugged in for long periods.
- Heat buildup can weaken internal components, making them more likely to short-circuit and spark a fire.
- If the charger is plugged into a damaged or loose outlet, it can increase the risk of fire even further.
While modern, high-quality chargers have built-in safety mechanisms, older or counterfeit chargers may lack these protections. Unplugging your charger when it’s not in use is the simplest way to eliminate this fire hazard.
2. Wasted Energy: The Cost of Phantom Power Consumption
Did you know that leaving your charger plugged in contributes to your electricity bill?
- Chargers still consume electricity even when no device is connected—this is known as standby power drain.
- A single charger might use only a small amount of electricity, but when millions of people leave chargers plugged in worldwide, the wasted energy becomes staggering.
- Over time, this unnecessary power consumption increases your electricity bill and contributes to higher carbon emissions.
While the cost per charger may seem small, it adds up—especially if you have multiple chargers and devices around the house.
3. Wear and Tear: Shortening Your Charger’s Lifespan
Leaving a charger plugged in 24/7 puts unnecessary strain on the charger and the outlet.
- Internal components degrade faster, reducing the lifespan of your charger.
- The outlet can loosen over time, increasing the risk of electrical arcing, which can lead to sparks and fires.
- Chargers left plugged in for long periods can become less efficient, meaning they might take longer to charge your phone over time.
By unplugging your charger when it’s not in use, you extend its life and reduce the risk of damaging your electrical outlets.
4. Increased Risk of Power Surges and Electrical Damage
Power surges happen more often than you think—whether due to lightning, faulty wiring, or sudden voltage spikes.
- When a charger is plugged in without a phone attached, the surge can damage the charger itself.
- If the surge is strong enough, it can spread to other connected devices and fry your phone or tablet the next time you plug it in.
- Using a surge protector can help, but the safest option is still to unplug chargers when they’re not in use.
What Experts Say: The Importance of Electrical Safety
Electricians and safety experts consistently warn against leaving chargers plugged in when they’re not needed.
- Many fires linked to electrical malfunctions start from overheating chargers.
- The National Fire Protection Association (NFPA) advises that small electronic devices should be unplugged when not in use to reduce fire risk.
- Experts recommend using high-quality, certified chargers and avoiding cheap, knockoff brands, which often lack safety features.
If you want to protect your home and your devices, it’s time to make a small but impactful change.
How to Safely Manage Your Chargers
Now that you know the risks, here are some simple ways to safely handle your chargers:
- Unplug chargers when not in use – This is the easiest and most effective way to prevent fires, save energy, and extend your charger’s lifespan.
- Use a power strip with a switch – If unplugging is inconvenient, use a power strip with an on/off switch to cut power to multiple chargers at once.
- Invest in high-quality chargers – Choose brand-name or certified chargers that meet safety standards. Avoid cheap, off-brand versions.
- Inspect your chargers regularly – Look for frayed wires, overheating, or any signs of damage. If a charger feels too hot, it’s time to replace it.
- Keep chargers away from flammable materials – Never place them on beds, sofas, or carpets where heat can build up and start a fire.

Final Thoughts: Small Habit Changes Can Make a Big Difference
It might seem harmless to leave a charger plugged in without your phone attached, but the risks outweigh the convenience. Overheating, wasted energy, charger damage, and fire hazards are all real concerns that can be easily avoided with a simple habit change.
By unplugging chargers when they’re not in use, you’re protecting your home, saving money, and reducing your environmental impact. It’s a small step that makes a big difference in the long run.
So, the next time you unplug your phone, don’t forget to unplug the charger too!
How should you react to survive when you suddenly fall into deep water without knowing how to swim?
Falling into deep water unexpectedly can be a terrifying experience, especially if you don’t know how to swim. Panic sets in, your instincts tell you to struggle, and before you know it, you’re exhausted and in real danger. However, survival in such a situation is entirely possible if you remain calm and follow a set of simple but life-saving steps.
According to Dr. Nash and his team of researchers, the key to survival is overcoming fear instincts and following five crucial steps. These steps are designed to help anyone—regardless of swimming ability—stay afloat, breathe, and increase their chances of rescue. Let’s dive into these life-saving techniques.
1. Stay Calm and Relax to Achieve Natural Buoyancy
The first and most critical step is to fight the urge to struggle. Many people instinctively flail their arms and legs in a desperate attempt to stay above water. However, this only wastes energy and causes faster exhaustion.
Instead, take a deep breath and allow your body to relax. When you stop panicking, your body will naturally float closer to the water’s surface. The human body is slightly less dense than water, meaning that if you remain still, you can achieve buoyancy without much effort.
2. Tilt Your Head Back to Keep Your Airway Clear
Once you’ve calmed yourself and started floating, you need to ensure that you can breathe. The best way to do this is to tilt your head back, keeping your face above the water.
Try not to move too much, as sudden movements can make you sink slightly. If you feel yourself going under, resist the urge to panic—simply take a deep breath, relax your muscles, and allow yourself to rise again.

3. Breathe Slowly and Avoid Inhaling Water
Now that your nose and mouth are above water, it’s time to focus on breathing. Many people instinctively gasp for air, but this can lead to choking if water splashes into your mouth. Instead, practice controlled breathing:
- Exhale slowly through your nose to clear any water that may have entered.
- Inhale through your mouth in a controlled manner.
- If a wave covers your face, hold your breath momentarily, then resume normal breathing.
Even experienced swimmers can struggle if they inhale water, so maintaining steady breathing is crucial for survival.
4. Move Your Arms and Legs Gently to Stay Afloat
At this point, you should be floating on the water’s surface and breathing steadily. The next step is to use gentle, controlled movements to maintain your position.
- Use slow arm movements: Move your arms in a sweeping motion, like you’re making small circles in the water. This will help you stay afloat without expending too much energy.
- Legs should remain still if you don’t know how to kick properly: If you’re unsure how to tread water, keeping your legs still is often better than kicking randomly. Let them sink slightly while focusing on keeping your upper body above water.
The key here is to avoid frantic movements—slow and deliberate strokes will keep you afloat much longer.
5. Look for Rescue Opportunities
Once you’ve gained control of your breathing and movements, your next priority is finding a way to safety.
- Scan your surroundings – Look for anything floating that you can grab onto, such as a buoy, a log, or even a piece of debris. Holding onto something will help you conserve energy.
- Check your distance from the shore – If you can see land, assess whether it’s possible to move toward it using slow, steady movements.
- Signal for help – If there are people nearby, shout for help. However, conserve energy by calling out only when necessary.
If you’re caught in a strong current, do not try to swim directly against it—this will only tire you out. Instead, swim diagonally at an angle to gradually move out of the current’s pull.
What to Do If You See Someone Drowning
If you witness someone struggling in deep water, it’s important to act quickly but safely. Jumping in to rescue them may seem like the right thing to do, but unless you’re a trained rescuer, it could put both of you at risk.
Instead, follow these steps:
- Shout instructions – Encourage the person to follow the survival steps above. Remind them to relax, tilt their head back, and float.
- Find a flotation device – If possible, throw a life jacket, a rope, or any floating object they can grab onto.
- Call emergency services – Immediately contact your local emergency number and provide details of the situation.

Why Staying Calm is the Key to Survival
Many drowning incidents occur not because the victim physically sinks, but because they panic and exhaust themselves. Learning how to override panic instincts and follow a survival routine can mean the difference between life and death.
Dr. Nash explains:
“Whether you’re planning a vacation, taking a walk near a river, or going for a swim, knowing how to stay safe in water is crucial. These simple survival techniques can save your life or someone else’s.”
Final Thoughts
Surviving a fall into deep water without knowing how to swim is possible—but only if you remain calm and follow the right steps. By floating, maintaining steady breathing, and making slow movements, you can conserve energy and increase your chances of rescue.
Now that you know these survival strategies, share them with your friends and family. You never know when this knowledge might save a life!
