Yes, that's exactly right. I started doing the power consumption measurements when I noticed that the batteries in my 49g+ flashed with newRPL seemed to keep going flat, even though the same calculator with HP ROM 2.15 had not drained its batteries in several years of occasional use. I believe that one other 49g+ newRPL user has reported the same issue earlier in this thread.

I got my HP 49g+ many years ago, shortly after it was released. I seem to remember that early versions of the ROM had a battery draining problem that went away when HP issued an update - was it ROM 1.20? Maybe the two problems have a similar cause.

Edit: It was ROM 1.22 that fixed the battery life problem - see https://www.educalc.net/281487.page . I don't remember any details, unfortunately.
