    Over past week or so my battery is draining very fast even when it's locked and in my pocket. Fully charged at 7am and by lunch lost over 35%

    Have not installed any new apps

    Does anyone else have similar battery usage or CPU usage as me, over the same period?

    Here is my battery usage

    This happened to me too. Sent it back to BlackBerry for repair, and everything. They sent it back unable to reproduce the problem after a security wipe. Turns out they were right and the security wipe "fixed" the problem. Six months later, still ok.

    Save yourself some time, back it up, do a security wipe, start over fresh. (don't restore from the backup. )

    Security wipe is an option, but not ready to pull that lever yet!

    A clean install will help. If you don't want to, maybe Sachesi will do.

    Do you have an SDCard in your Passport? Try pulling it and rebooting.
    I have had a problem with my Bold and my Passport where they go into an endless cycle of trying to refresh the media list from the card.

    Decided to switch off my 'Data Services' and my drainage was back down to single figures over an 8 hr period with c. 80% left.

    It's the LTE signal then that is causing the System usage to be very high!

    That is very strange, because I have 4gLTE on my Passport (T-Mo), and I routinely get more than two days on a charge with normal usage.

    If you want to keep Data Services on but want to disable LTE, try this,

    Signal strength could be the reason.

    BB10 does that randomly
    Clearly your system is using up the battery.
    Something is stuck due to which the system is using up your battery
    A simple restart should help (press both the volume keys together until you see the BlackBerry logo on the screen)

    Do you have an issue with your Hub?, I had severe battery drain like yourself and worked it out to be the hub, you could try resetting the Hub.
    For Hub, if the device has been restarted, try refreshing the Hub view. To do this, while viewing Hub swipe down from the top right corner on a 45-degree angle towards the bottom left the of the display five times. After doing this, Hub will restart, and should show your data.

    Whenever I've had this problem, it was because some account was refreshing too often - like an email or Facebook account set to check for immediate updates.

    Security wipes work because they reset all of these to defaults like, "check every 1 hour." If you don't want to do a wipe, you might get the same result by just going through your accounts and checking how often they refresh.

    Couple of months ago I had that problem. Source was an app from Amazon that used active GPS constantly and ran headlessly in the background. It was a tracking app.

    I uninstalled it, and a couple of others, then rebooted which fixed the battery drain. Now have GPS/location turned off unless I specifically want to use it.
