I have read many threads on battery life related issues and many potential solutions. It seems that most people take the phone off the charger in the morning and plug in at night. Even still, the % reported at the end of the day don't sound encourging. I didn't have my Hero long enough to accurately observe the battery life. I am now awaiting replacement. So, can the Hero go 24, 36, maybe even 48 hours with low to moderate use? A few calls, some web, some amount of SMS, and so on. If there is no data for that, what is your "end of day" battery % under _heavy_ use? Thanks.
