The Amazon Fire TV Stick 4K is a popular solution for converting standard televisions into smart TVs, but concerns often arise regarding its electricity consumption when left plugged in for extended periods. To address this, the technology outlet Canaltech performed specific energy tests to determine if the device significantly impacts household utility bills.
During the evaluation, the Fire TV Stick 4K remained powered on and continuously streamed movies via Disney+ to simulate real-world usage scenarios. The team conducted two separate tests on different days with varying durations. The first test, carried out on October 20, lasted six hours and recorded a cumulative consumption of just 0.01 kWh. The second test took place the following day, running for nine hours and 22 minutes, yet it also registered only 0.01 kWh. Combined, these sessions totaled 15 hours and 22 minutes of operation with a total energy draw of 0.02 kWh.
Canaltech noted that the meter used for measurement displayed results to two decimal places, which explains why both tests yielded identical readings despite the difference in runtime. Small variations in consumption likely fell below the threshold required to register on the device. Nevertheless, the data confirms that the Fire TV Stick 4K maintains extremely low energy usage under these conditions.
Based on these findings, the outlet calculated an average consumption rate of approximately 0.0013 kWh per hour. Using this figure, they projected monthly costs for a 30-day period across different daily usage patterns: four hours, eight hours, twelve hours, and continuous 24-hour operation. The estimated monthly consumption ranges from 0.156 kWh for four hours of daily use to 0.937 kWh for non-stop operation.
To translate these figures into financial impact, the analysis applied reference electricity rates from five Brazilian cities: Fortaleza, São Paulo, Curitiba, Manaus, and Brasília. The results indicate that even in a worst-case scenario of 24-hour daily usage, the estimated monthly cost does not exceed one Brazilian Real (R$ 1) in any of the evaluated locations. For instance, in São Paulo, using the device for eight hours a day would add an estimated R$ 0.30 to the monthly electricity bill.
It is important to clarify that these projections are based on rounded meter readings and continuous playback tests; they do not represent precise measurements of standby power consumption or account for variations in actual usage conditions. Additionally, the nominal power capacity of the device's power supply does not equate to its actual energy draw at all times. Despite these limitations, the study concludes that the Fire TV Stick 4K has a negligible impact on electricity costs during movie playback, making it unlikely to be a significant concern for household budgets even among heavy users.
