IKEA Tradfri - Batteries in the remote controls are quickly discharged

For several weeks I have had a problem with batteries that power IKEA Tradfri remote controls. New batteries discharge only after a few days and the remote controls stop working. All devices work in a small apartment, I did not change their position and previously I did not have such problems (I have been using this equipment for almost 2 years). Could this be caused by incorrect configuration in HA? I will be grateful for your help.

• Replace the batteries, fiddle with the buttons randomly until it re-pairs (i.e. (+) Add New Device). Yes, this may take a while. Remove the batteries for a few hours, and try again.
• Enable firmware updates in ZHA as newer software has improved matters.
• Add a mains powered Zigbee device(s) to act as a router (ZR) - e.g. a TRADFRI control outlet.
  Mains powered radios can shout louder, and help move from point-to-point to mesh topology.
• Add any Zigbee device(s) to increase the amount of mesh coverage.
  More devices help move the topology from point-to-point to mesh.

If this helps, this post!
