How to remove sleep mode on Xiaomi devices: TVs, smartphones, smart watches

Why Xiaomi Device Is Constantly Sleeping and How to Fix It

Sleep mode on Xiaomi devices is an energy-saving feature that automatically turns off the screen, dims the backlight or puts the gadget into a low-consumption state. On Mi TVs and Redmi Smart TVs, it activates after 15-30 minutes of inactivity, on smartphones (Redmi Note series, POCO, Mi) after 1-2 minutes, and on Mi Band or Watch smartwatch watches after 10 seconds. The problem is that sometimes sleep mode is too aggressive: the screen goes out while reading, the video stops, and smart devices stop responding to commands.

In 80% of cases, the faulty power saving settings are to blame, but there are other reasons: on Xiaomi TVs 2023-2026, sleep mode can block the output due to a bug in the MIUI TV 3.0+ firmware, which requires manual cache reset.
