- PossiblePhysical damage causing a shortA cracked circuit board or liquid damage can create a constant small drain.
What to do
- Check for anything pressing a button, especially if the remote was left in a couch or under something.
- Switch to name-brand alkaline or lithium batteries instead of generic ones.
- Remove batteries when the remote won't be used for an extended period.
- If it's a Bluetooth/voice remote, check the device's settings for any always-listening or backlight feature that can be adjusted.
- Inspect the remote for visible damage, sticky residue, or signs of liquid exposure.
- Test with a fresh set of batteries and time how long they last under normal use to see if drain is truly abnormal.
Tools and parts
- Fresh batteries
When to call a pro
Not typically needed; a remote confirmed to have a short from damage is usually more practical to replace than repair.
