Battery and CM5 uConsole

I bought 2 new batteries Panasonic NCR18650B protected cells recommanded here for a 4 h00 usage time . I put them 1/4 hours and I lost 30 % without any usage of clockpi . Is there a meaning to reduce this ?

I don’t have a uConsole yet, but from what I’ve read so far, 4 hours is a reasonable estimate for working with a CM4. However, the CM5’s power consumption is significantly higher than that of a CM4.
