    I'm just wondering how long does your battery last after updating to cyan? Whether preview for developers or just the normal cyan update??

    I have a 620 with Amber. With Windows 8 it will last more than 2 days.
    With Windows 8.1 it only lasts 6 hours. I have tested with Amber and Black and it's the same.
    The phone keeps warm all the time and the battery drains fast.
    I can't test Cyan because it's not available for the 620, but I am dubious about the battery duration.

    Some say a hard reset is recommended before doing an OS update I think so the changes in everything are more obvious. Just back your phone up best you can and hard reset then update to preview again immediately after. The battery life should be better afterwards.
    Don't forget to load in your backup after all of that lol :P

    Maybe your data is on and a lot of background apps are on??

    No. It's a fresh install with DevPreview after that. There are some threads about it.
    If I turn wifi off and phone to Plane mode (phone off) it's the same.
