HTC EVO 4G :: Battery - Rom - Kernal?

I just ordered the seidio battery for my phone (3500). the battery widget i downloaded is telling me 92% left on battery, and the little icon in the task bar is showing completely full.

Are the widgets pretty accurate with what they display as to what's really left on the battery?

also, when I first got this battery, I put it on the external charger for 12 hours(tuesday night). what else do i need to do to ensure it's going to fully charge while charging IN my phone? This morning this is what I did: charged til all the way green, turned phone off, charging light turned back orange so i waited until it was green again, booted into recovery using clockwork, and then wiped battery stats. this only being my second charge, i know it can take up to 5 or 6 charges to reach battery's full potential, but i have unplugged it and not really used it since 7:30am. my battery widget is telling me I only have 90% left (dropped 2% already while posting this). that seems like it drained that first 10% really quickly. also, i have made another thread about my phone being awake 100% of the time, so I am sure this is contributing to it.

Here is all the info about my phone:
I am rooted.
Rom: 3.26.651.6---Froyo DeOdexed RevE3
Kernal: 2.6.32.15-g746f4f0
htc-kernal@and18-2 #58
PRL Version 60670
PRI Version 1.34_003 (which I can't get updated no matter what i've tried)
baseband version 2.15.00.07.28

I'm using HTC Sense as my launcher.

I am using multicon so i can utilize more of my homescreen with more apps. Other than that, not using any other widgets besides the weather widget.

I can't figure out what's keeping my phone awake. how do I ensure that my battery is going to get a FULL charge while IN my phone.

Trouble updating PRI

I can't get wireless tether to work. (a whole other issue)
