I was told to completely drain the battery once in a while so the device will recognize the lower limits and give a more accurate reading. I ran Slacker until the phone died, then pull the battery, wait a minute, insert battery, power on, repeat. I had to do this probably 4 or 5 times.

When it finally wouldn't make it to Sense without shutting down I pulled the battery for 30 minutes. Put the battery back in and booted one more time. It made it to sense once more, so I left it alone and went to sleep. To my surprise, the phone was still powered up the next morning. I started Slacker and it died almost within a few minutes. Plugged in the charger, powered on, and left it alone until fully charged.

I noticed a great difference after all that. YMMV.
