All of the information for this study of Sony TVs was gathered from the official Sony 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 Sony TV you are interested in.
How Many Watts do Sony TVs Use?
As stated earlier, 32 inch to 85 inch Sony TVs use between 35.6 watts and 429.9 watts, on average.
The average power for all of the Sony TVs studied was 162.6 watts when in On mode.
It’s important to realize that the amount of power a Sony TV uses will depend not only on the screen size but the type of backlight LED technology used.
Sony has the following different types of TVs:
We created the following chart to help you see how Sony TV power increases as screen size gets larger.
It’s easy to see the relationship between TV wattage and TV size, however, it’s worth mentioning that larger TV screens tend to have high resolutions like 4k (2160p) and 8k (4320p), which require much more wattage.
The 75 inch Sony TVs appeared to use more power than expected compared to the 65 inch and 77 inch TVs.
It’s very important to remember that the numbers here are the average of the typical power consumption numbers reported by Sony. 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!
The chart below shows the minimum, average and maximum TV wattage for the Sony TVs we reviewed.
Overall, there wasn’t a huge variance between the minimum and maximum TV wattage for the individual Sony TV class sizes.
Sony TV Wattage by Screen Size
LED 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 wired connections.
Based on the previous two chart, it’s easy to see that Sony TV wattage increases with TV 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.
|TV Screen Size||TV Wattage (Average)||Sony Model|
|32 Inch||35.6 Watts||KD-32W830K|
|43 Inch||74.5 Watts||KD-43X85K|
|50 Inch||94.8 Watts||KD-50X85K|
|55 Inch||117.4 Watts||XR-55A95K
|65 Inch||147.9 Watts||XR-65X90K
|75 Inch||219.9 Watts||KD-75X85K
|77 Inch||166.3 Watts||XR-77A80K
|83 Inch||162.5 Watts||XR-83A90J
|85 Inch||259.7 Watts||KD-85X80K
Sony TV Wattage by Resolution
The breakdown of Sony TV resolution is shown in the pie chart below. There weren’t any full high-definition, 1080p, TVs in this review.
The 4K TVs, or 2160p resolution, was the most common type.
High-definition, or HD, is 720p and was only found in one Sony 32 inch TV.
The newest 8K resolution was only found in larger TV screen sizes from 75 inch to 85 inch.
The following table lists the average Sony TV power by screen resolution to provide an idea of how TV watts go up with resolution.
|Name||Resolution||TV Wattage (Average)||TV Percentage|
|High-Definition (HD)||720p||35.6 Watts||3%|
|Full High-Definition (Full HD)||1080p||-||-|
How Much Electricity Does a Sony TV Use Per Hour, Month and Year?
The amount of electricity used by any modern 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 85 inch Sony TV, which uses 260 watts to operate, it would take 260 watts divided by 1000 to get 0.260 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.
However, the Energy Star standard has determined that 5 hours with the TV in On mode and 19 hours with the TV in Standby mode, is the norm for households.
Therefore, you can determine how much energy is used in a day by multiplying the hourly power times 5 and then adding that to the standby mode power (0.5W) times 19 hours.
You simply take that daily power much and multiply it times 365 to get your yearly TV electricity average!
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.
Sony TV Power Consumption by Screen Size
The average Sony 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!
|TV Screen Size||TV Energy Per Hour||TV Energy Per Month||TV Energy Per Year|
|32 Inch||0.036 kWh||5.6 kWh||68.4 kWh|
|43 Inch||0.075 kWh||11.5 kWh||139.5 kWh|
|50 Inch||0.095 kWh||14.5 kWh||176.5 kWh|
|55 Inch||0.117 kWh||17.9 kWh||217.8 kWh|
|65 Inch||0.148 kWh||22.5 kWh||273.3 kWh|
|75 Inch||0.220 kWh||33.3 kWh||404.8 kWh|
|77 Inch||0.166 kWh||25.2 kWh||307.0 kWh|
|83 Inch||0.162 kWh||24.7 kWh||300.0 kWh|
|85 Inch||0.260 kWh||39.2 kWh||477.5 kWh|
Sony TV Power Consumption by Resolution
Sony 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.
|Name||Resolution||TV Energy Per Hour||TV Energy Per Month||TV Energy Per Year|
|High-Definition (HD)||720p||0.036 kWh||5.6 kWh||68.4 kWh|
|Full High-Definition (Full HD)||1080p||-||-||-|
|4K||2160p||0.153 kWh||23.3 kWh||283.4 kWh|
|8K||4320p||0.383 kWh||57.8 kWh||703.0 kWh|
