Power Consumption
OLED vs QLED power consumption 2026: real watts, real $/year
For typical mixed viewing, OLED uses about 30 percent less power than Mini-LED QLED. For peak HDR brightness, Mini-LED uses less. Annual electricity cost difference for typical 65 inch use: $10 to $20. Not enough to drive the buy decision but real.
65 inch power consumption table
SDR average measured at typical user brightness setting. HDR peak at 100 percent full-field. Annual cost based on 5 hours daily at $0.16 per kWh (US average).
| Model | Panel | SDR Avg | HDR Peak | Annual Cost |
|---|---|---|---|---|
| LG C5 65" | WOLED | 105W | 320W | $31 |
| LG G5 65" | WOLED | 115W | 340W | $34 |
| Samsung S95D 65" | QD-OLED | 125W | 380W | $37 |
| Sony A95L 65" | QD-OLED | 120W | 370W | $36 |
| Samsung QN90D 65" | Mini-LED | 145W | 420W | $42 |
| TCL QM8K 65" | Mini-LED | 160W | 550W | $47 |
| Hisense U8K 65" | Mini-LED | 150W | 480W | $44 |
| Samsung Q80D 65" | LED-LCD | 95W | 180W | $28 |
Annual cost across electricity rates
Power costs vary widely by region. The annual cost of running a 65 inch OLED at 5 hours daily (105W average):
| Region | Rate | OLED $/year | Mini-LED $/year |
|---|---|---|---|
| US national average | $0.16/kWh | $31 | $42 |
| Texas | $0.14/kWh | $27 | $37 |
| California | $0.29/kWh | $56 | $77 |
| UK average | £0.25/kWh | £48 | £66 |
| Germany | €0.40/kWh | €77 | €106 |
Based on 65 inch flagship, 5 hours daily, SDR average use. Rates as of April 2026.
The OLED dark-content efficiency advantage
OLED's per-pixel control creates a fundamental efficiency curve: a fully black pixel draws zero current. For movies with letterbox bars, dark drama scenes, or night-time gaming, large parts of the screen contribute nothing to power draw. Mini-LED's backlight runs constantly even when local dimming reduces output in dark zones.
This is why OLED tops Energy Star ratings for the per-mode test cycle (which uses varied content) but Mini-LED tops sustained-full-field brightness efficiency tests.
