I recently got this battery here's my experience
Firstly, I did get mine for free from verizon. Tip (tell the rep about how your phone dies quick then the phone's led blinks amber when you plug it in.) Secondly, I am running CM7 latest nightlies with the governor set to performance, overclocked, screen brightness is auto, wifi off 90% of the time, bluetooth and gps on 100%.
Here is my usage on a typical work day
I use pandora probably for at least 3 hours a day with bluetooth connected (keep in mind that I use the high quality music setting and turn off the auto screen lock so the screen is on that whole time. I will typically need to use gps for about 15-30 minutes. I'm not a txter at work so minimal txt usage, I will make 3 or 4 phone calls. I will also browse the web for about 30 minutes.
With this usage I get a solid 8 hours out of this battery so most of the time my phone is dying or dies on the car ride home. (I do have a charger but after a day of work sometimes it's nice to let my phone die) If I have a day full of appointments however I will have plenty of battery life left. I almost never put my phone on the charger until its dead and the first few cycles I really drained the battery to the point that it wouldn't turn on and would charge it all night powered off.
Overall I recommend it. I don't know how I lived without it. I hope this long winded reply is helpful to someone. Enjoy!
