    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.

    My 1520 got hot and began the crazy drain this morning. Turned off, waited 5 minutes to cool down, turned back on and all is well. (Fingers crossed.)

    battery draining is too fast, also taking too much time get recharged as well

    Odd you should say that, I charged my 1520 yesterday and I thought it took ages to charge, just checked insider pro and my charge rate was jut 21% per hour. It is usually twice that.

    I had an odd problem. Phone was charged to 100 % before I updated. When update was finished I had less than 30% battery left.

    And the update didn't even take 5 minutes.

    That is common. I think the upgrade process doesn't do any power management and totally kills the phone.

    My phone even died mid-update. Thankfully after applying power it upgraded ok.

    In future, I'll always plug in.

    Edit: 5 mins is pretty bizarre though!

    The update DOESN'T kill the battery at all. The battery still has the same charge, it is just that the OS calibration will be non existent until it is charged and drained a few times. SOP for WP8....

    Stable on my Lumia 1020 and have the Cortana live tile on. Battery life has never been better. Sorry to hear that you have battery life issues on the 1520 and hope you're able to get them resolved.

    Very good on my 920...
    Had a strange password sync problem with the primary account... don't know if it was related to the update or fooling around with the VPN.
    Point is.... I did nothing with the account/passwords..... but then had issues.
    Fixed it somewhat quickly...but it wasn't intuitive...

    I initially thought there was some heat/rapid battery exhaustion.... but that's a difficult call as it's 105 to 114degF (39 - 42degC) here.
    Regardless, am not noticing that at present.
