I'm running MR5 on my phone and can run through the day with normal reception.

I used to run my phone to disallow roaming, but since set it to automatic. I've found that the battery life has improved significantly for some reason and can easily last the day now as opposed to before when it would only last for about 6-9 hours.

Also I've found that leaving Opera on in the background can kill the battery in about an hour or two, especially if you left it on a site that constantly polls for data, like the finance.google.com's tickers.
