You switch off the television before going to bed. You unplug the kettle after making your morning coffee. You turn off the lights when you leave a room.
So why does your electricity bill still seem higher than you expected?
One of the reasons could be something many people don’t realise exists: standby power.
Many modern appliances continue to use small amounts of electricity even after they’ve been switched off. Individually, the amount of power they consume is often quite small. However, when you add together dozens of appliances running 24 hours a day, every day of the year, the cost can become noticeable.
The good news is that reducing this hidden electricity usage is often easy once you know where to look.
In this article, we’ll explain what standby power is, highlight ten common appliances using electricity when switched off, and share simple tips to help reduce unnecessary energy consumption.
What Is Standby Power?
Standby power, sometimes called phantom load or vampire power, is the electricity an appliance uses while it appears to be switched off.
Many modern appliances never completely power down unless they are unplugged or switched off at the wall.
This happens because they continue performing background functions such as:
- Waiting for a signal from a remote control
- Keeping a digital clock running
- Maintaining a Wi-Fi or internet connection
- Downloading software updates
- Powering memory settings
- Supporting fast start-up features
Although these functions don’t use large amounts of electricity individually, they continue operating around the clock.
Think of it like a dripping tap. One drip doesn’t seem like much, but over weeks and months, those small amounts begin to add up.
How Much Can Standby Power Cost?
It’s difficult to put an exact figure on standby power because every home is different.
The total cost depends on factors such as:
- The number of appliances in your home
- The age and efficiency of those appliances
- How long they remain on standby
- Your electricity tariff
A single appliance may only use a small amount of electricity while on standby, but most households have many devices quietly drawing power throughout the day and night.
Reducing standby power alone probably won’t halve your electricity bill, but it is one of the easiest ways to eliminate unnecessary energy waste. Combined with other energy-saving habits, it can contribute to meaningful savings over time.
1. Televisions
Modern televisions, especially Smart TVs, are one of the most common sources of standby power.
Even when switched off using the remote, they often continue to:
- Wait for remote-control signals
- Stay connected to the internet
- Download software updates
- Maintain network settings
The small standby light on the front of the television is a reminder that the TV hasn’t completely switched off.
Tip: If you won’t be using the television for several hours, switch it off at the wall or use a switched multi-plug.
2. Decoders and Streaming Devices
Devices such as DStv decoders, Android TV boxes, Apple TV devices, streaming sticks, and other media players often remain active even when they appear to be off.
Many continue to:
- Download updates
- Maintain internet connections
- Refresh programme guides
- Stay ready for instant start-up
These devices are often among the larger standby power users in an entertainment system.
3. Phone and Tablet Chargers
Have you ever left your phone charger plugged into the wall after removing your phone?
Many chargers continue drawing a very small amount of electricity even when no device is connected.
While the amount is minimal, unplugging chargers when they’re not needed is a simple habit that improves safety and helps reduce unnecessary electricity usage.
4. Microwave Ovens
Most microwave ovens display the time continuously.
That digital clock requires electricity 24 hours a day.
The power consumption is usually quite low, but because microwaves are rarely unplugged, they remain permanent standby users in many kitchens.
5. Coffee Machines
Many modern coffee machines stay partially powered so they can:
- Heat water quickly
- Maintain programmed settings
- Display digital clocks
- Prepare for scheduled brewing
If you only use your coffee machine once or twice a day, switching it off completely between uses may save unnecessary electricity.
6. Gaming Consoles
Today’s gaming consoles are far more than gaming devices.
Many continue to:
- Download updates overnight
- Charge controllers
- Stay connected online
- Support instant start-up modes
If you’re not planning to play for a while, consider enabling energy-saving settings or shutting the console down completely.
7. Desktop Computers and Monitors
Putting your computer into sleep mode is convenient, but it isn’t the same as switching it off.
Both desktop computers and monitors often continue using small amounts of electricity while sleeping.
If you’re finished for the day, shutting the system down completely can reduce unnecessary power usage.
8. Printers
Wireless printers are designed to remain available whenever you need them.
That means they often stay connected to your Wi-Fi network and wait for incoming print jobs.
Although their standby consumption is generally low, they still contribute to your home’s overall phantom load.
9. Sound Systems and Home Theatre Equipment
Amplifiers, speakers, receivers, and soundbars frequently remain on standby so they can be switched on instantly with a remote.
If your entertainment system includes several devices, their combined standby power can become more noticeable than that of a single appliance.
A switched multi-plug makes it easy to power everything down at once.
10. Air Conditioners
Even when switched off, many wall-mounted air conditioners continue powering internal electronics.
This allows them to:
- Receive signals from the remote
- Monitor temperature settings
- Restart quickly when needed
Although standby usage is usually modest, air conditioners are another example of appliances that are rarely completely disconnected from power.
Are These Appliances Really Costing You That Much?
The honest answer is yes, and no.
For most households, standby power is not the biggest contributor to an electricity bill. Appliances such as geysers, heaters, ovens, tumble dryers, air conditioners, and pool pumps typically consume far more electricity.
However, standby power is different because it often goes completely unnoticed.
Instead of one appliance using a lot of electricity, you may have twenty or thirty appliances each using a little.
Together, those small amounts can become a meaningful part of your monthly consumption.
The goal isn’t to unplug every appliance in your home. Instead, it’s about identifying the devices that don’t need to stay powered all the time.
Simple Ways to Reduce Standby Electricity Usage
Reducing standby power doesn’t require major lifestyle changes.
Here are a few practical ideas:
- Use switched multi-plugs for televisions and entertainment systems.
- Unplug phone and tablet chargers when they’re not in use.
- Switch off gaming consoles completely when you won’t be using them.
- Enable energy-saving modes on compatible devices.
- Turn off computers and monitors overnight instead of leaving them in sleep mode.
- Replace older appliances with more energy-efficient models when the time comes.
Small changes repeated every day can make a noticeable difference over the course of a year.
Don’t Forget the Biggest Electricity Users
While reducing standby power is worthwhile, it’s important to focus on the appliances that use the most electricity.
In most South African homes, the biggest electricity users include:
- Electric geysers
- Portable heaters
- Air conditioners
- Tumble dryers
- Pool pumps
- Ovens and stoves
If you’re looking to make a significant impact on your electricity bill, these appliances deserve your attention first.
Reducing standby power should be viewed as one part of a broader energy-saving strategy.
Understanding Your Electricity Usage Is the First Step to Saving
The best way to reduce electricity costs isn’t simply to switch everything off. It’s to understand where your electricity is going.
Once you know which appliances consume the most power, and which ones quietly use electricity in the background, you can make informed decisions about your daily habits.
For many homeowners, landlords, and businesses, prepaid electricity meters also make it easier to monitor consumption and budget more effectively. By seeing electricity usage more clearly, it’s often easier to identify patterns and find opportunities to reduce unnecessary waste.
Final Thoughts
Many of the appliances we use every day continue consuming electricity long after we’ve pressed the “off” button.
Fortunately, most standby power is easy to reduce through a few simple habits.
By switching off appliances that don’t need to remain on standby, using switched multi-plugs, and paying attention to your home’s biggest electricity users, you can take practical steps towards lowering your monthly electricity bill.
No single change is likely to transform your energy costs overnight. But when small improvements are combined with smarter electricity habits, they can make a meaningful difference over time.
