    I have noticed that my Z10 battery drain is ridiculous when I turn off wifi. In battery guru my standby voltage runs between -.4 and -.7 in a wifi zone. If I turn off wifi it shoots to -1.5 with a strong signal regardless off which network I am on. I tested airline mode and it drops to -.07. Anyone else see this same issue?

    Have you downloaded the latest update? This update is supposed to improve battery usage.

    In airplane mode my Z10 uses 0.03W.
    In H+ it uses 0.04W.
    With wifi on it uses 0.05W.

    Those values are all obtained with only battery guru running and leaving the phone still for at least 4 minutes prior to checking.

    You are talking watts right? You had stated volts in your OP.

    The OS only sends info to battery guru every 2 minutes when not plugged in. Are you sure you waited long enough in standby until you checked the usage?

    Yeah, it does drain quite a bit when I'm off wifi too. But it's not too bad though.. enough to get me through the day with moderate usage

    If you don't need LTE speed, then disable it and force 3G. You'll see your batterie usage improving considerably.

    Yes I meant watts. I have let it run for over 30 minutes to see if it would settle but it keeps draining. I have LTE turned off as I am not in a service area that supports it. I am going to do a wipe and clean OS install and see if it improves.

    Unless my BES account is to blame I believe the issue is fixed. I have done a full OS Reload and the drain issues are gone. The only account I don't have on currently is my corporate email as it needs to be reset.

    That would be nice but some US carriers block that option.
