If you are being serious we could probably help you. That is terrible, and it has happened to me at least once with every phone I've owned, so I believe you.
Does that happen every night?
I'm dead serious. My phone has less than 6 hours of standby.
I plug it in every night before bed. If I don't it will be dead by morning.
I just installed the Task Killer a couple weeks ago to see if it would help. I've uninstalled it.
I also turned off all my syncs except for Gmail today, to see if that helps.
I bounce between 3g/4g at work, but have no 4g at home.
Display is at about 30%.
It's an uneasy feeling to know that if I don't have access to electricity, I'll be incommunicado in a few hours.
