Battery Life Management (Vogue, dHarvey)

[Temujin]

I am currently running the latest dHarvey Black Vista ROM.

In the past 13 minutes, my phone has gone from fully charged to 95%. The only usage I had, other than unplugging it, was receiving and checking 3 push emails, which I promptly closed. I then turned off the screen.

Why is my battery dying so quickly? I had the same issue when I installed the ROM on the dead pixel phone (which I exchanged for this one.) This phone is only a day old, so it makes absolutely no sense for the battery to be this weak.

My bluetooth is off, I don't have any applications running. Even so, my processor usage is 45-50% and the battery drain is constant.

Some people have suggested to disable the built-in weather client (how?). It's exceptionally convenient for me, so I'm hesitant to do so. Can anyone else confirm this?

Another post said I should let the battery die all the way and keep turning on the phone till there's none left. I should then keep doing this each time I use it for several days, as I need to "teach" the battery/processor circuitry the true size of the battery (which was reset somehow during an upgrade).

Any further suggestions or comments on the aforementioned methodology?
