I have the same question. I did the update to 2.2 on my wife's and my Dinc. My phone has been running ok - battery life has been a lot worse but the extra features are worth the extra charging for me.
My wife wants to go back to 2.1. Her phone was almost fully charged last night and when she woke up this morning her phone was dead. Her battery life has been terrible since installing 2.2.
Any ideas on how to go from 2.2 to 2.1? It seems like such a stupid question after waiting impatiently to get 2.2 for the last two months.

There is a way! These are the steps I followed exactly, first one is to downgrade back to 2.1, second one is to root, root forever, update your radio, upgrade to froyo:

Well, glad you figured out a way! Good luck with that. I wouldn't want to go back to 2.1 where there is no flash support for sure! Now you can watch any of the videos and see all of the flash. You can even watch myspace videos anything on espn.com That feature alone is great.
Baul about your wife, the battery life on the 2.2 isn't THAT much worse. It does, on mine, not everyones, go down a little faster but it's not to an extreme it doesn't seem like. Check and see if she had something on all the time that shouldn't be or some sort of app.
Or else she loses flash which might not be important to her. If not then go for it.
But I can only imagine as we keep going most of the new apps will be tailored to run on 2.2 so she might run into issues. A few months from now pretty much every app will be designed to run with 2.2 when they build it.

If you haven't already downgraded, you might try the following to help your battery life.
Go to Menu, Settings, Wireless & networks, Mobile networks and uncheck Enable always-on mobile data. Click OK.
When I first got my phone back in May, I had bad battery life. Did the above and the battery life improved quite a bit. After upgrading to Froyo, I had poor battery life because this was checked by default. Unchecked it and things improved again.

But I guess if you aren't the type to get a lot of e-mail and no one sends you pictures then it would be okay.
All I see is checking and unchecking mobile network. And you don't have to go into settings to do that. If you want to turn it off and on faster just add the mobile network widget to a screen. The widget is already on your phone. Just long click a blank spot on the screen and click widgets and find the power widget's and there will be one for gps, wifi, and mobile network.
But mobile network is something that's always on for me! I don't want to have to go turn it on every time I want to go to the browser or use an app that uses the internet and people send me picture messages and I like my email.
As I said before, if it does save some battery life it can't really be all that much. And it's just not worth it to me.

I know that it may seem not right, but, at least on my phone, I still get my email in real time, Twitter updates, and of course I can browse the web and manage my servers remotely via SSH. I don't know about messaging (MMS etc), since I don't use it.
If you Google this setting you will find a lot of info on the web. Unfortunately, I have not found a definitive explanation of what this setting does and what apps are affected by it. I don't seem to have problems on my phone. All I am suggesting is that people experiment with the setting and if it works for you, you will probably experience much better battery life. If it doesn't work, set it back.

Since I don't use these type of apps, this works for me. I still get my email in what I believe to be real time and other updates see to happen as well.
