BUT, it may be a good idea anyway, what with the chance of increasing resistance from Amazon to owners having control of their device.
There are a couple more that I have been testing on a couple of machines, but do not intend to post anything until we see how things develop.

I don't think it's a problem specific to factory firmware. There are plenty enough PW4 battery life complaints from people who've never jailbroken their Kindle.
I'm on production fw5.10.1.2 and SKIP_UPDATE_CHECK made a huge difference in my PW4's battery life when wifi is on. At one point, battery was draining at 1-2% per hour on standby if I forget to turn off wifi (need it while reading for KOReader progress sync).
Looks like 5.10.x has gotten quite aggressive when it comes to phoning home...
