When you choose a new Xiaomi TV or already use it, the issue of power consumption becomes critical — especially with the rising electricity tariffs in 2026. Many users are surprised to see the receipt for lights is 10-15% more than usual, without even knowing that it may be the fault of the TV running in the background for the day. In this article, we will examine the real energy consumption models Mi TV and Redmi Smart TV — from the compact 32-inch to the giant 75-inch — and learn how to calculate monthly consumption and reduce it without compromising comfort.
The manufacturer specifies averages, but they often don’t take into account standby, screen brightness, backlight activity, and even content type (a 4K movie consumes more than YouTube HD). We tested popular Xiaomi models with a wattmeter and collected data from lab tests to provide you with current consumption figures in 2026, taking into account updated firmware and energy-saving algorithms, and you will learn how the settings of the AI Picture Engine and Adaptive Brightness affect light bills, and why even a turned-off TV can “eat” up to 5 kW per month.
Real consumption vs. real consumption: where is the truth?
Xiaomi’s technical specifications always include two key parameters: power in running mode (e.g., 120W for the Mi TV Q2 55) and standby consumption (typically 0.5-1W). However, these figures are only the tip of the iceberg. First, they are measured at standard brightness (200 cd/m2), whereas in home conditions users often put 300-400 cd/m2 for comfortable viewing during the day.
- 🎮 Game Mode – Increases brightness and refresh rate;
- 📺 Watch it. HDR-content (before) +30% to basic consumption);
- 🔊 Use of built-in speakers at maximum volume;
- 🌐 Background work of applications (for example, Google Assistant or Mi Home).
For example, Xiaomi Mi TV P1 65" on the passport consumes 180 watts, but when watching a movie in 4K HDR with Dolby Vision enabled and the brightness of 350 cd / m2, the real value reaches 240-260 watts. And if you add sound through an external sound panel connected by HDMI ARC, the total consumption can exceed 300 watts!
⚠️ Note: Xiaomi models on MediaTek processors (e.g. Redmi Smart) TV X43) Standby uses up to 1.5 watts, which is 50% more than devices on Amlogic (e.g. Mi). TV A Pro. This is due to the background operation of the chipset for quick switching on.
Table of power consumption of popular Xiaomi models (2022-2026)
| Model | Diagonal | Consumption (W) | Standby mode (W) | Annual consumption (kWh) |
|---|---|---|---|---|
| Redmi Smart TV X32 | 32" | 45–60 | 0.8 | 120–150 |
| Mi TV A Pro 43" | 43" | 70–90 | 0.5 | 180–220 |
| Xiaomi TV Q2 55" | 55" | 120–150 | 1.0 | 300–360 |
| Mi TV P1 65" | 65" | 180–240 | 1.2 | 450–550 |
| Xiaomi TV Master 77" | 77" | 250–320 | 1.5 | 600–750 |
The data in the table are given for the average use case: 4 hours of active viewing per day (of which 1 hour is content in the Internet). 4K HDR) 20 hours in standby mode. Real consumption may vary by ±20% depending on:
- 🔄 Screen refresh rates (60 Hz vs 120 Hz);
- 🌡️ Temperatures in the room (when heated above 30)°C consumption increases by 10-15%);
- 📶 Wi-Fi signal quality (weak signal makes module work harder).
How to calculate monthly electricity consumption?
To find out how much kW your Xiaomi TV eats in a month, use the formula:
(Power in running mode × Watch hours per day × 30 days) + (Consumption in waiting × 24 hours × 30 days) = Monthly consumption (Wh)To translate to kWh, divide the result by 1000. For example, for Mi TV Q2 55" with 4 hours of viewing per day:
(135 W × 4 × 30) + (1 W × 24 × 30) = 16,200 + 720 = 16,920 Wh = 16.92 kWh/month
Multiply this value by the rate per 1 kWh in your region, and at an average price of 5 rubles per kWh (for Moscow in 2026), we get:
16.92 × 5 = 84.6 rubles / month - only for TV!
⚠️ Note: If you use Always On Display, add to the calculation +5-7 kWh per month. This feature is activated by default on Mi models TV Master and Mi TV P1.
Turn off Always On Display in Settings → Display|
Set a sleep timer for 2-3 hours of inactivity|
Use the "Energy Saving" mode in Settings → System|
Turn off the TV from the outlet at night (waiting mode "eats" up to 3-5 kW / month)|
Reduce the brightness to 200-250 cd/m2 for evening viewing-->
Hidden Energy Eaters: What You Didn't Consider
Even if you turn off the TV with the remote control, it still consumes electricity.
- HDMI-CEC and ARC: If other devices (set-top box, sound bar) are connected to the TV, the HDMI-CEC function keeps them hot by adding +0.3–0.7 W to the consumption in wait.
- Wi-Fi and Bluetooth: The modules remain active for remote control via Mi Home or voice assistant. This is +0.5-1 watts.
- Auto-Update: Xiaomi TVs check updates once a day, briefly switching on for 2-3 minutes. This adds ~0.5 kWh per month.
- Advertising modules: On models with PatchWall (India, global versions), background banner loading increases consumption by 5–10 W during downtime.
To check your actual consumption, use a wattmeter (costs 500 rubles) or a smart power monitor (e.g. Xiaomi Mi Smart Plug) to plug your TV in and analyze the weekly data, and you’ll be surprised how much energy goes “to nowhere.”
How to completely disable background processes?
Comparison with competitors: who is more economical?
Xiaomi TVs are traditionally considered energy efficient thanks to optimized processors Amlogic and MediaTek, but in 2026 they were overtaken by some Samsung and LG models with MicroLED technology and improved backlight control algorithms.
| Brand/Model | Diagonal | Consumption (W) | Technology |
|---|---|---|---|
| Xiaomi Mi TV Q2 55" | 55" | 120–150 | QLED |
| Samsung QN90C 55" | 55" | 100–130 | Neo QLED |
| LG C3 55" | 55" | 90–110 | OLED |
| TCL 55C735 | 55" | 130–160 | QLED |
As you can see, Xiaomi loses 20 to 30 percent to LG OLED, but it beats TCL and some Sony models. Xiaomi TVs have a big advantage in terms of price and energy efficiency. For example, the Redmi Smart TV X43 is 30 percent cheaper than the Samsung CU7000, but consumes only 10 percent more.
💡
If you choose between Xiaomi and LG, keep in mind that OLED-panel LG It is more economical when watching dark content (for example, movies in theatrical mode), but lose QLED Xiaomi in brightness in daylight.
How to reduce consumption without loss of quality?
You can reduce your light bills by 20 to 40 percent without sacrificing comfort.
- 🌓 Adaptive Brightness: Include Adaptive Brightness in Settings → The display. The TV will automatically dim the brightness in the dark.
- ⏱️ Sleep Timer: Set up an automatic shutdown after 1-2 hours of inactivity in Settings → System system → Timer.
- 🔌 Smart socket: Connect your TV through a timer socket (like Xiaomi Mi Smart Plug) and set up a complete power outage at night.
- 🎵 External sound: Use a sound bar or headphones instead of built-in speakers – this will reduce the load on the TV amplifier.
Another effective method is to disable unnecessary functions:
- 🚫 Always on Display (additional) ~0.5 kW/month);
- 🚫 Voice assistant (saves up to 0.3 watts in wait);
- 🚫 Auto-Update (replace manual check once a month).
⚠️ Note: On Xiaomi models with Google TV (Like Mi. TV Google Edition: Background activity on Google services can add up to 10W to consumption. Turn off sync and geolocation in account settings.
💡
The easiest way to save money is to reduce the brightness from 100 percent to 70 to 80 percent, which will reduce the consumption by 15 to 20 percent, and you won't even notice the difference when you look at it in the evening.
