Help Battery life cut in half, after update to 2.2

[gme109]

I had the same issue the first time I updated my phone to 2.2, and had to exchange it out for a refurb with 2.1. Now here I am again, with 2.2 and lousy battery life. I even turned off the Sprint ID in running services, and my battery is at 45% after 4 hrs. of being mostly in standby. Anyone else experiencing bad battery life after going to 2.2?

Yes, or at least it appears to be... The status bar one is showing much higher than my battery life widget is. I will try the "battery pull, holding down the power button for 15 seconds with it out" method again after I charge it fully. So, it may just be a reporting error on the widget, or I am hoping anyhow.

But one strange thing is when I go under Battery Use, it is only showing Display (97%) and Cell Standby (3%), with the TWS at 35%...nothing else is showing up... Even though I would normally see Swype, Messaging, Browser (or Internet now I suppose). I even played around with FPse for awhile, and that isn't showing up...

I found this thread on XDA Forums... I am currently in the process of testing it out to see if it helps anything...

It suggests running the battery calibration after any new kernel installation, which would be part of the upgrade...

I did the steps from the link above, and I can confirm greatly improved battery life... Part of it may be due to switching to SyndicateRom, but after doing this, 43 hours, and 20% battery remaining...
