    LOL, thank you, I meant, I do know what fastboot is and I never have it checked/on, but I just don't know what is causing the drain. I don't feel like doing a factory reset and having to set everything back up. Usage says my camera is using anywhere from 27% to 33% of my phones energy. Does anyone know if I clear out the data and cache of the Camera app in the Apps section, if it will mess up the camera functions?

    I don't think the option should even be offered anymore (more negative than positive) or at least the default should be OFF.



    .
    I think they did change the default to off this go around.

    I noticed mine was off, but I assumed it just remembered that from before the update. Anyway, I hope you are right!

    OMG! The camera should not be using that much power unless you have been actively using it a LOT. Clearing out the cache of the camera app won't hurt it (it will forget your settings only) but it shouldn't make any difference either. Did you reboot like I said to?

    Remember- the usage history is since the last charging session. The numbers are not terribly useful until the phone has been off the charger for quite a while. If you take it off the charger, use the camera once, then go look at the history, it is going to look like the camera is using a huge amount of power (which it is, but only because you haven't done anything else yet).

    I did reboot, but still says the same thing in Usage. Maybe I will try clearing it out. I am assuming that the only thing I will have to change once I use the camera again is where to save photos to. So, it is safe to clear the camera data and cache?

    Yes and yes. Then perhaps reboot it again, put it on the charger until it is full, then take it off and use (or not use) it normally for a few hours and look at your power history again.

    Tank you for the suggestion! I love these forums. I like to be able to give help and get help so fast!

    Google now is turned off and my battery is back to like it was before the update. Very happy. Let's see if it lasts.

    You made some other changes too, so it is hard to be conclusive. But it does have face validity based on other postings and the way Google [Spy] Now seems to work. Since it is always "on", recording where you go, what you do, etc, it stands to reason it will be using significant power. Will be interesting to see if anyone else with battery issues has the same result when just turning off Google [Spy] Now without making any other changes...

    (I am not a good test, because I never allowed it to start in the first place).

    I've done 5 total factory resets 2 of which I wiped the cache partition to try to fix my proximity sensor issues and each time the fast boot was checked off....so I think that's a good sign =).

    For what it's worth, I have left it enabled, but have disabled Location History within Google Maps (which Now uses for some of its functionality, but which isn't required) and it seems to have made a huge difference in battery conservation. Please try this and let us know if it also seems to work for you. It'd be great to find a way to keep Now enabled for those who want it but still not completely sacrifice all battery life.

    Seems like location history is causing Maps to turn itself on and drain the battery.

    I'm off charger for 8 hours and I'm at 75% with Google Now on...I don't think Google Now is that big of a battery drain...

    Well, I wish it wasn't for me, but it really was. I will try going back to it, but so far I am thrilled with battery life since I turned it off.

    I've also seen a difference after doing the same thing. It's a bit early to tell but I compared one hour to the next and saw much less battery drain.

    I have had 20-30% increase in battery usage for example, playing podcast uses more battery than it did before. The phone is on power saving mode. It reminds me the poor battery life of the first evo.

    So far my battery's been somewhat similar as before. I'm losing about 10% more per day than before, which isn't terrible and still leaves me at around 60% at the end of the day. Something I noticed today, the OS upgrade turned NFC back on. I usually keep this off by default. Check if yours is on. If you don't use NFC, it might help your batter life a bit.

    I just enabled Google Now, and am now going to select only a few cards that I want on(weather, sports, emergency alerts) and I turned off Location History. I want to see how much of a difference it makes for me. On a side note, what do most of you have set for your GPS settings. I have Google's Location Service, Location & Google Search, and Compass Warning all checked and GPS satelites unchecked.
