Am I the only one to notice the battery drains faster than before?

I always keep my vera3 updated. I remember the “heal” was remove several months ago. It looks like the battery drained faster than before since then. For example, I have to change batteries for Yale real living deadbolt every 1.5 months now (it was > 6 months)

Am I the only one to notice this?

BTW, I’ve confirmed the polling had been set to “0” already.
