The thread for the GSM version over at xda has a short but sweet quicklist of battery-related tips for use with EnergyROM, quoted below. I don't know if any of the rilphone.dll stuff applies for our CDMA carriers as I rarely see it mentioned over here at PPC (whereas at xda there are stickied threads about it). Anyways, beside rilphone.dll these are some pretty good tips -- especially the one about waiting a few charge cycles (or days) to see how it 'settles down'.

BATTERY SAVING TIPS
• There is nothing special about this ROM to make it use more power than other ROMs except that it is tweaked for performance over battery life.
• Make sure you follow all of the flashing instructions to the letter. Especially the part about the hard reset.
• Backlight is set to high. You might want to change that.
• 3G is on by default. Recommendation is to turn it off when you are not surfing the internet.
• If your radio does not match your rilphone.dll you can get crazy bad battery drainage. Make sure they match. There is a separate thread for that.
• Check to see that some application is not still running in the background. Check, do not assume. USe the full Task Manager application.
• Check to see if the screen is still on when you expect it to be off. Soft reset can fix that issue.
• Some radios work better with some carriers and locations. Asking everyone to tell you what radio to use may not give you the best answer. Be specific about your situation.
• The battery meter will not settle down and give accurate readings for a few battery cycles. Give it a while.
• For the first few battery charging cycles, try to charge to 100% with phone off and then allow battery to drain down quite a bit before recharging. Thisis so the meter will calulate drain well.
• Don't drain your batery all the way down until it dies. Not good for these types of batteries.
• The GPS sucks the battery dry. If you want to keep track of yourself, consider something like GPSToday that only wakes up the GPS once in a while.
• Maybe you don't really need aGPS enabled. Disable and check GPS lock times and battery drain.
• Applications that run from the storage card consume more power so install oft-used or background-type applications to main memory.
