So turn off 4G LTE, turn off widgets, use a lower quality screen and keep chargers in all locations. How far does it go until the compromises outweigh the benefits?
Turning off 4G only really applies if you're not in a 4G area. Which should be obvious. You could do it anyway if you are in a 4G area but realize you don't need 4G speeds, but then why buy the Bionic if you're not going to use it for what it's best at? Might as well get the Droid X2 and save money.
Lower quality screen is a conscientious choice you make when purchasing the phone. There are plenty of others - the Droid Charge, for example - that have "superior" screens. Then again their batteries aren't nearly as good as the Bionic.
Chargers everywhere - unnecessary if you learn how to master the the art of using what you need and then closing it, which isn't too much. Think about it - do you REALLY access Twitter 10 hours a day? Doubt it. Chances are you do quick checks/updates every now and then, but you don't need to leave the app running to do those. Same with Facebook, same with whatever else.
It's the same logic as with lights in rooms. Why leave lights on in rooms that nobody is in? Use the light when you are in the room, turn it off when you leave. Run A/C or heater when people are in the place, turn it off when you're not. That's how you keep energy bills down. Same concept with the Bionic.
Now, you don't HAVE to do any of these things. Nobody's forcing you to do anything else. But you can't have it both ways. Either you are conservative with usage and get great battery, or do whatever you want and accept the battery will be trashed (unless/until you buy an extended).
