    Not sure why this worked. But i went into clockwork and reset battery stats and my phone has never ran this long on the battery. Usually after 8 hours of work and phone usage i need to recharge and im at 20% left. After reseting the stats i am at 50% left going on 13 hours of use including an hour of pandora and two hours of PE :).

    Actually I did this a few days back and have noticed a little bit of improvement myself.

    Essentially the same as a power cycle. The phone has to relearn the charge points on the battery in both cases.

    How exactly did you do the reset? In nandroid? or in Clockworkmod? or in the system itself.

    Reboot into clockwork and its under advanced I believe. I did it on a full charge, don't know if that makes a difference.

    is there any harm in this? what exactly does it mean when the phone has to relearn the charge points of the battery?

    Your phone is smart, but the battery is dumb. When the battery voltage hits a certain point the phone reads it as "full", etc. However, when the phone gets topped up it doesn't always report full correctly, and the net result is an early "full" charge. The phone translates this, over time, into incorrect charge points. 100%, 90%, 80%, etc. When you force the phone to relearn these points you get a more correct charge -- in other words, a fuller charge. This means more battery life. :)

    I have had battery issues for some time now. It got to the point that I had to buy another battery, and a wall charger also to swap when the other dies, I have a backup. Over the weekend I ran this, clearing the stats.. Today I have barely used the phone (read and sent aprox 5-7 txts) was at 100% at 8:30am, by 3pm, it was at 10%. Then, get this, I get in the car shortly after 3pm, plug it in, and about 15 minutes later I am at 70%... This is a big issue.. Who really knows what the true battery level is? this is annoying..

    I'm assuming you're rooted, so I have to ask are you overclocking? Have you cleared your Dalvik cache recently?

    That kernel ate my battery alive, so I swapped to P3Droid's LV 125-1200 kernel. That little bit extra on the top end makes up for the lack of compache so far, and it runs MUCH cooler for me as well as another 25-33% more run time, but YMMV. I don't know how well a P3 kernel would play with BB on your phone. :)

    You'll lose some boot speed the first time you boot your phone up after clearing. The phone has to rebuild the cache, but it's AMAZING how much gunk builds up in that thing. Should clear it every couple of weeks you don't do a full system wipe.

    I will give P3Droid's LV 125-1200 a look and also clear that cache.. As for the profiles, I dont know, I think that is something that petes rom does automatically...

    Can this be done any other way other than using clockworkmod?
