I have updated my 1520 yesterday morning to the latest 8.1 DP, build number 12397.895. Post update I am getting crazy battery drain when on standby mode and device gets hot. My wife's 720 is having the same build but the device is not suffering the problem.
I have only noticed the issue when I reached home last night and not being connected to a Wi-Fi network. I am connected to cellular data right now(always turned off when not in use) so I am testing whether issue is related to device not being connected to a data network.
