    I have had extreme battery drainage over the weekend. My phone was at about 70% when I went to sleep when I woke up it was at 30% which never happens. I took some screen shots of the apps running in the background. I've had my classic since June. I did a hard reset, but it didn't change anything. Any advice would help!

    Based on your graph, your battery lasted almost 20 hours or so before you plugged your charger in, although your Standby battery usage is fairly high. My recommendations would be to switch to 2G/3G and connect to Wi-Fi if available. Only switch to 4G if needed. Using a pouch or a case with a flap that can shut off your device's screen can also be helpful. Now if that doesn't work, you may need to reload your OS. Just backup first using BlackBerry Link.

    20 hours is good for the Classic. So you were asleep for the 20 hours? You don't plug it in when you go to bed?

    I charged it during the day. I only charge it when it goes down to 20%. Now I don't notice any battery drainage. I just noticed this morning that it was at 30% then when I got out of church around noon it was a 19% which was weird because it was in my purse and I wasn't using it

    Well sometimes BlackBerry 10 devices go crazy and eat up your battery for no apparent reason. System's battery usage go way beyond a 100% which would cause your device to heat up without you not even doing anything. Restarting your device, most of the time, will fix it.

    Several situations can lead to battery drain when phone is idle...OS changes, app installs or updates, background app permissions, device location, network access to name a few.
    Always a good idea to reboot or restart phone periodically to "clean" it up.
    As mentioned your usage history isn't terrible at all and likely something I've described contributed to your quick drain.
    Glad to hear that it's not draining any longer.
