How Many Watts Does a Samsung TV Use?
Samsung TVs use different amounts of power based on their size and model. Small models 32 inches or less use 30 to 60 watts, while models 65 inches or more use 150 to 300 watts or more. How you actually use your TV depends on how you set the picture, especially how bright it is. The exact number is helpful if you want to keep an eye on your electricity bill or just want to know how much power your TV is using. This guide tells you what changes the amount of power your Samsung TV uses and how to get the exact numbers for your unit.
Key Factors Affecting Samsung TV Wattage
How much electricity your Samsung TV needs every day depends on a number of factors. Six main factors, listed here from most to least important, cause the power needs of different models to change a lot.
Screen Size
The main thing that affects power use is the size of the screen. To keep the brightness even across a larger screen's surface, it needs more lights. An increase in size of a certain amount (from 43" to 55", or 65" to 75") requires an increase in power.
Display Technology
Samsung offers several display technologies, each with different energy characteristics:
LED-backlit LCD TVs use light-emitting diodes to illuminate the screen from behind. This traditional technology forms the foundation of Samsung's lineup.
QLED TVs add a quantum dot layer that improves color while maintaining comparable power efficiency to standard LEDs.
Neo QLED TVs utilize mini-LED backlighting technology for more precise brightness control, potentially improving efficiency despite higher performance.
OLED TVs operate fundamentally differently since each pixel creates its own light. This results in varying power consumption based on content-darker scenes use significantly less power than brighter ones.
Resolution
TVs with better resolutions (4K and 8K) need more processing power than 1080p TVs. However, this doesn't have as much of an effect on power use as screen size or display technology.
Brightness and Picture Settings
Did you know your viewing choices directly impact power consumption? From subtle brightness adjustments to the dynamic peaks of HDR content, your television's energy use can vary significantly. That's why the EcoFlow DELTA 2 Max, equipped with an advanced and long-lasting LiFePO4 battery, is the ultimate power solution for all your televisions. Whether you're enjoying the energy efficiency of an LCD or the vibrant brilliance of an OLED, the DELTA 2 Max ensures seamless power delivery, even during those power-intensive bright scenes of your favorite HDR content.
Smart Features
Modern smart features add to power consumption even in standby mode. Wi-Fi connectivity, voice assistants, and advanced gaming features all contribute to increased energy usage.
Model Year and Series
Newer types usually have better energy efficiency built in. Most of the time, premium series have better power control technology than budget lines. This means that even though they have more features, they may use less power overall.
How to Find the Wattage of Your Specific Samsung TV
While the previous section explained general factors affecting power consumption, you likely want to know exactly how many watts your particular Samsung TV uses. Here are three reliable methods to find this information.
Check the Label on the Back of Your TV
The quickest way to find your TV's power rating is to look at the label on the back panel:
Locate the technical specifications sticker or plate on the rear of your TV
Find where it says "Power Input," "Power Consumption," or similar wording
The wattage is typically shown directly (example: "AC 100-240V ~ 50/60Hz 150W")
If you only see voltage and amperage listed, you can calculate the maximum wattage using this formula:
Watts (W) = Volts (V) × Amps (A)
For example, if your label shows "100-240V ~ 1.5A," your TV's maximum power consumption would be approximately 240V × 1.5A = 360W at peak. However, actual usage is typically much lower during normal viewing.
Consult Your User Manual
If checking the back of your TV is inconvenient, your user manual contains the same information:
Look in the "Specifications" or "Technical Information" section toward the end of the manual
Find the power consumption listing, which often shows both typical and maximum wattage
Some manuals also include standby power consumption figures

Visit Samsung's Official Website
Samsung’s website provides comprehensive specifications for all current and many older models:
Find your exact model number (usually on the TV’s back label, starts with UN, QN, or similar)
Visit Samsung’s website and search for your model
Go to the “Specs” or “Specifications” tab on the product page
Look for “Power” or “Power Consumption” in the technical details
The website typically lists both “Typical Power Consumption” (average during normal use) and sometimes “Maximum Power Consumption” (highest possible usage).
General Wattage Ranges for Different Samsung TV Types/Sizes
Here are the typical power consumption ranges for Samsung TVs by category in a more organized format:
| TV Type and Size | Typical Power Consumption |
|---|---|
| Small LED TVs (24-32 inches) | 30W to 60W |
| Mid-Size LED TVs (40-55 inches) | 60W to 150W |
| Large LED TVs (65-75 inches and larger) | 150W to 300W or more |
| OLED TVs (mid-size) | 80W to 200W (more efficient with dark content) |
| OLED TVs (large) | Can exceed 200W (varies with content) |
| 8K TVs | 150W and upwards (higher than equivalent 4K models) |
These figures represent general ranges based on information from Samsung. For your exact model's power consumption, please use the methods described in the previous section to find your specific TV's wattage.
How TV Settings Change Your Samsung's Power Usage
While the physical characteristics of your TV determine its baseline power consumption, your settings and usage patterns have a significant effect on day-to-day electricity use.
Picture Modes: 20-40% Power Difference Between Settings
Samsung TVs come with several preset picture modes, each with vastly different power requirements:
| Picture Mode | Power Impact | Description |
|---|---|---|
| Vivid/Dynamic | Highest usage (up to 30-40% above Standard) | Maximum brightness and contrast, intense color processing |
| Standard | Moderate usage (baseline reference) | Balanced settings for average rooms |
| Movie/Cinema | Reduced usage (10-15% below Standard) | Lower brightness, more accurate colors |
| Eco/Energy Saving | Lowest usage (20-30% below Standard) | Automatically adjusts brightness to minimize power |
The difference between Vivid and Eco mode on the same TV can be substantial - potentially cutting power use by up to 50% in some models.
Brightness Settings: Each 20% Reduction Saves 10-15% Power
Brightness directly correlates with power consumption. Each step you reduce brightness translates to measurable power savings:
Reducing brightness from 100% to 80%: Saves approximately 10-15% power
Reducing brightness from 100% to 50%: Saves approximately 25-30% power
Reducing brightness from 100% to 30%: Saves approximately 40-45% power
Finding the right balance between comfortable viewing and energy efficiency often means setting brightness based on your room’s lighting conditions rather than leaving it at maximum.
Standby Power: 0.3-0.5 Watts Used When "Off"
Samsung TVs continue to draw power even when “off” to maintain:
Quick-start capabilities
Network connectivity
Software update readiness
Voice assistant functionality
Modern Samsung TVs typically use between 0.3-0.5 watts in standby mode - a significant improvement over older models that could use 3-5 watts or more. While this amount seems small, it adds up over time:
0.5W standby × 24 hours × 365 days = 4.38 kWh per year
At $0.15/kWh, that’s about $0.66 annually just to keep your TV ready to turn on
For comparison, fully unplugging your TV when not in use could save enough electricity to power a laptop for several hours each year.
Three Ways to Reduce Your Samsung TV's Power Consumption
Having learned how much power your Samsung TV consumes, here are some useful ways to lower consumption:
1. Activate Eco Mode or AI Energy Mode in Settings
See these power-saving options under Settings → General → Power and Energy Saving. The default Eco Mode automatically reduces screen brightness, therefore saving 15–20% of the power consumed. By varying settings depending on what you are viewing, AI Energy Mode on more recent Samsung TVs (2021+) saves power without compromising picture quality.
2. Lower Brightness to 50-70% and Reduce Contrast Enhancer
More power is used in brightness changes than in most other settings. For typical evening viewing, try putting it between 50 and 75 percent instead of full-on. Look at the Expert Settings also and turn the Contrast Enhancer to Low or Off. For most shows, this performs rather effectively for QLED TVs and can save 10 to 15 percent of electricity with minimal effect on picture quality.
3. Turn Off Ambient Mode and Set Sleep Timers
Ambient Mode—the one that displays images or art while you're not watching—uses between 30 and 80W based on the kind of TV you have. Make sure you disable Frame TV while not using it if you have one. Program your TV's sleep timers so it never spends hours in rest mode at once. It increases TV lifespan and saves power. For those concerned about power outages affecting your entertainment setup, the EcoFlow DELTA 2 Max with its 2400W output can keep your Samsung TV and other essential electronics running during blackouts, while its multiple AC outlets accommodate your entire media system.
