1. Backlit buttons
A remote with a light-up keypad uses more power every time the light is on. If the remote or its settings let you switch the backlight off, do it to save power.
2. Accidental presses
A remote in a bag, pocket or sofa cushion can be pressed by accident, often with the TV or streaming box switched on. Keep it somewhere it won’t be pressed.
3. Mixed or old batteries
Mixing old and new cells, or cheap and branded ones, can make a remote seem to die early. Replace them all together with the same type.
4. Heat and storage
Leaving the remote near a window or heater speeds up self-discharge. If you won’t use it for months, take the batteries out.
