How Many Watts Does a Samsung TV Use? [69 TVs Reviewed in 2023]

Samsung TV Watts, Power and Energy Consumption Explained

With fast-rising electricity prices, you might be asking yourself the question, “How many watts does a Samsung TV use?”

Obviously, you’d have to be thinking about purchasing a Samsung TV, or maybe you already have one to think of that, but it is a valid question.

That might not always be the first thing on someone’s mind when purchasing a TV, but the lifelong expense of powering modern TVs is something that should be considered when picking the TV size, resolution and features as it all starts to add up in hidden costs over time.

To help answer the question about Samsung TV wattage, we reviewed and analyzed 69, unique, Samsung TVs. We will provide the average power consumption numbers for the TVs, and we will show you how much energy the TVs can consume in a year.


  • On average, Samsung TVs use 103.3 watts when in On mode and 0.5 watts when in Standby mode.
  • Samsung TV wattage varies from 27 watts for a 32 inch TV all the way up to 231 watts for a 85 inch TV.
  • Samsung LCD TVs use 191.1 kWh of electricity per year, on average.
  • Yearly TV energy consumption varies from 52.7 kWh up to 425 kWh per TV.
  • TV power consumption for Samsung models varies drastically depending on features like size, resolution, backlight type and audio power.

For more background information and terminology, we recommend you read our post on how many watts does a TV use?

All of the information for this study of Samsung TVs was gathered from the official Samsung TV website. The information was analyzed and summarized in this article and it’s only to be used for information purposes and as a general reference. To get the wattage and energy consumption numbers, you will have to fine the Energy Guide for the specific Samsung TV you are interested in.

How Many Watts do Samsung TVs Use?

As stated earlier, 32 inch to 98 inch Samsung TVs use between 27 watts and 231 watts, on average.

The minimum power consumed for a 32 inch TV was only 27 watts, but the maximum TV power was 231 watts for an 85 inch TV (not a 98 inch TV).

The average power for all of the Samsung TVs studied was 103.3 watts when in On mode.

To help visualize the patterns between TV size and power dissipation, we created the following chart. It’s easy to see that the TV wattage increases as the size of the TV increases, however, it’s worth mentioning that larger TV screens tend to have high resolutions like 4k (2160p) and 8k (4320p).

It’s very important to remember that the numbers here are the average, typical power consumption numbers reported by Samsung. They also provide the maximum power consumption numbers for most products and that can be two to three times as much as the typical power!

For example, the Sony 65″ Neo QLED 4K Smart TV has a typical power consumption of 104 watts. On the other hand, it has a maximum power consumption of 270 watts, which is 160% more power and energy!

The chart below shows the minimum, average and maximum TV wattage for the Samsung TVs reviewed in our study.

It’s worth noting that there are a few outdoor TVs in the dataset, so those have a much higher power requirement due to being outdoors and needing a brighter backlight.

This is the same as trying to view your cell phone in the sun and you need to turn up the brightness in order to see the cell phone screen, and as we all know, this drains the battery quickly!

Samsung TV Wattage by Screen Size

LCD TV screen size is the most popular way of choosing a TV, which is closely followed by resolution and other features like Wi-Fi, audio quality and if it’s a Smart TV or not.

Based on the previous two chart, it’s easy to see that Samsung TV wattage increases with TV screen size, so as a consumer you can expect the larger TVs to consume more energy and cost more to operate.

The following table puts the TV screen size and TV wattage side-by-side so you can easily see how each TV size compares to the other ones.

Samsung TV Wattage by Resolution

The breakdown of Samsung TV resolution is shown in the pie chart below.

As you can see, 2160p resolution was the most common, which is also referred to as 4K.

Full high-definition, or Full HD, is 1080p and was only found in two Samsung 32 inch TVs.

The newest 8K resolution was only found in larger TV screen sizes from 55 inch up to 85 inch.

The following table lists the average Samsung TV power by screen resolution to provide an idea of how TV watts go up with resolution.

How Much Electricity Does a Samsung TV Use Per Hour, Month and Year?

The amount of electricity used by any LED TV in an hour is very simple to calculate if you know how much power is uses in On mode. You simply take the wattage and divide it by 1000, which gives you the amount of energy in units of kWhs.

So, for the typical 55 inch Samsung TV, which uses 84 watts to operate, it would take 84 watts divided by 1000 to get 0.084 kWh of energy used in 1 hour.

In order to accurately calculate how much electricity a TV uses in a month, you need to estimate the amount of time the TV is going to be on and off.

Fortunately, the Energy Star standard has determined that 5 hours with the TV in On mode and 19 hours with the TV in Standby mode, or when it’s off, is the norm for energy guide calculations.

Simply multiply the daily electricity energy value times 30 days and you get the estimated amount of electricity used by a TV in a month!

If you have a specific TV, or even your own TV at home, and want to know this number, then simply look-up the energy guide online, or you might even find the yellow label on the back of the TV.

Samsung TV Power Consumption by Screen Size

The average Samsung TV power consumption, listed by TV screen size, is shown in the table below for hourly, monthly and yearly usage.

It’s important to remember that these numbers are just the average, and there’s a big difference between the minimum and maximum values for each TV screen size class, plus the maximum power that each TV can potentially use.

Hence, be sure to figure out how much power your specific TVs are using if you want to better understand just how much electricity your home TVs are using!

Samsung TV Power Consumption by Resolution

Samsung TV resolution plays a significant role in power consumption when comparing the same TV screen size.

As a good estimate, the amount of electricity is almost double as the resolution increases, or doubles!

Hence, a good understanding of how resolution impacts both TV energy consumption, and TV quality, is important when comparing TVs side-by-side.

The table below clearly shows that trend, though the size of the TVs also tend to get bigger when the resolution increases.
