    system cpu running at over 55% all the time

    we have 2 z10's - mine and my wifes - I updated both recently and my system cpu usage shot to 60+% and fluctuates from 30-60 all day long - the battery not only dies in 3 hours but is running at 34 degrees C which I can't believe is good for it - the odd part is her phone runs normal at 5-7% all the time and gets more than a solid day from the battery

    I've done all the suggested things I could find from screen resolution to making google mail 24 hrs to turning off wifi - what else can I do

    will doing a full factory reset using the security wipe and redoing all my eamail and s/w help?

    I've read some real horror stories on the security wipe so I hadn't done it yet - I was hoping for a simple "factory reset"
    thanks
    tom

    Try doing a backup, security wipe, and then restore.

    Depending on what kind of backup you decide to do, saves different things. For example, I only back up my "Settings" as it saves all accounts I have in my phone and I only need to re-enter the password to get them back and working again. You can also backup your apps, which will save app/game data, but I don't for the simple reason that I can easily just download everything from BlackBerry World (I also don't play games, so game data doesn't exist). I also don't back up my media because it's all stored on a SD card, so no worries there.

    So I'd recommend picking a backup, doing the backup, performing a security wipe (which if you let it do it's thing, shouldn't be an issue. It may take a while, but that doesn't mean it's broken), and then perform a restore.

    thanks I haven't bothered doing a back up as it wont take long to reenter my 3 email accounts -- do you have any idea why the system part of the cpu would be running at 55+ all the time?

    If you're on OS 10.2.1, you can go to Settings>Device Manager>App Manager and then select "CPU" and it will show what's currently using the processor.

    If you're anything below 10.2.1, the device manager isn't available. Have you installed any Android apps? Either via sideload or BlackBerry World? They have the ability to run headless without your permission.
