When it comes to the power a TV consumes in a day, it greatly varies from TV to TV as people use TV differently at different time duration. To find the wattage of the TV, you can either refer to the given chart below or simply Google it by entering your TV model, and brand’s name.
How Many Watts is a TV?
If you are wondering ‘how many watts is a TV?’ below is the power wattage of a normal LCD/LED:
| TV size | LED TV | LCD TV |
| 24-inch TV | 50 Watts | 40 Watts |
| 32-inch TV | 70 Watts | 50 Watts |
| 37-inch TV | 80 Watts | 60 Watts |
| 42-inch TV | 120 Watts | 80 Watts |
How to Find Watts Used in Your TV?
You can find how many watts your TV required per hour to run on their product page or backside of your TV. For Example, Here are the product details we found for Mi 43 Inch Ultra HD TV.
As you can see, it mentioned that Mi 43 HD TV needs 75 Watts per hour of power to run.
Used terms in LED TV power consumption
There are certain terms that one needs to be familiar with before calculating the LED TV power consumption. The following are such terms used more often that will help you in answering the question,’ how much electricity does a TV use?’:
Watt
It is the unit of power that usually refers to the rate at which the device uses electricity. For instance, if you are wondering, ‘how many watts does a TV use?’ a TV of 100 Watt will consume power at a rate of 100 Watt every hour and not 100 units of electricity.
Kilowatt
Although Kilowatt is also a unit of power, it is mainly used for devices that consume an immense amount of power. For instance, there is an air conditioner of 2.5 kW.
Kilowatt-hour
This unit is merely found in the electricity bill and is also known as Kilowatt-hour which refers to the energy that a device consumes. For instance, a TV is of 80 watts and has been running for 20 hours; it will consume watt-hours of 80 x 20 which is 1600 watt-hours. It also means 1.6-kilowatt-hours of electricity which is 1.6 units of electricity.
Electricity Tariff
By electricity tariff, it is usually meant the charge that the electricity provider asks for a single unit of electricity.
Operational hours
As the name suggests, operational hours usually refer to the total number of hours that a certain device is running. Thus, if you use your Television for a total number of 10 hours, then the same is the operational hours of your TV,
Factors affecting TV Power Consumption
Certain factors affect the TV power consumption and they are as follows:
Your TV’s age
If the TV is old then it may require 400 watts and sometimes, even more, will hence disable the overall monthly electricity bill.
Your TV’s size
The TV’s size equation goes by, the larger the TV size, the more power it will consume. If your TV size is somewhere about 15 inches then the LED TV will consume an average negligible daily cost.
Type of Screen
The power profile of LCD is the same as LED, whereas, in the case of other plasma screens, the latter uses several three times much energy. This is the reason why switching to LED from plasma screens has shown a massive drop in the overall electricity bill.
Tips to reduce TV Power consumption
If your electricity bill is a big load on you, then you can put in the below-mentioned efforts to reduce the TV power consumption:
Reduce the backlight setting
Backlight is a major contributor to draining the power lowering it will greatly help in reducing the power that a TV usually consumes. Instead of going for a bright backlight, opt for either placing your TV in a dimly or dark lit environment
Turn off the TV
Though this may be a mainstream option it indeed helps in cutting down the electricity bill as opposed to people who unnecessarily keep their TV on running mode.
Turn the TV accessories off
Here, accessories mean turning off all the accessories that are somehow related to your TV in case you are not using it for a certain moment.
Make sure there are no standby mode
For this, you need to turn off your setup box as well as the TV when it is no longer in use. This approach should be followed even though the phone is not in any standby mode.
The always ON Feature
In case of the always ON feature, make sure to turn it off in case you are not interested to use them. The options here are point and change, Bluetooth, and voice control.

Conclusion
Thus, if you are skeptical of the question,’ how many watts does the TV use?’, above are some of the points that will help you in figuring out the answer. To validate the calculation of TV power consumption, make sure to multiply the rated power by the operational hours. To follow up the calculation of the electricity bill for the month, make sure to multiply the power consumed by the TV in the entire month with the electricity tariff. Therefore, with the raging rise in electricity bills, make sure you approach methods such as switching to energy-efficient TV for example the LCD, LED, GLED instead of Plasma TV, or CRT.
