I replaced my battery icon with Add On Creator last time, hence the different battery icon (showing 100%). forgot abt it, sorry for that
Use Root Explorer, delete the loopy smoothness script in system\etc\init.d  u'll be amazed at the changes aft u delete tat script!!

You must set up your APN for internet.
You need one if you are using pirated, Warez and low rating apps in the market.
Flashing a kernel cannot wipe your system. The file you used must contain a script that does the wiping.

that was quick. No love for touchwiz? Juice defender is recommended since battery drain is still present in cm7 #104 - although I found it had been greatly improved compared to nightlies #85

I also use green battery power saver that intermittently switch off and on my phone data internet.

Click on the graphs and look at the hardware usage of the battery.

Loopy smoothness script is a script that tries to make the dialer have a higher priority, but it's a constantly repeating script that can drain battery as well as making other apps unresponsive or creating lags. Best to let Linux manage the "nice"ness of each app and delete that script. Some devs already commented about it that its not doing anything good to the phone. Wonder why ROM chefs are always including it in their ROMs.
Odexed ROMs are the way to go. Simplicity and Milky are both fine ROMs.
When it has a red dot, it means all radio interfaces are disabled (Wifi/3G are examples of radio interfaces)
How long was display on? Display eats a lot of battery. Best is to use minimum brightness to reduce battery usage. Only use auto-brightness when you're outside.
If you are on JVR, you can install $omator's Stock+. It includes the disable converting to MMS for long messages along with other things including extended power menu, statusbar icons with battery values etc.

Freeze or remove the screen capture app in Titanium backup? Or just don't press the buttons that will do a screen capture?
Juice defender's role is to disable radio interfaces at certain intervals to save battery. When its disabled, it will show a red dot, but you can configure it manually to enable/disable at certain time/situations also.

Yes, autobrightness means the brightness will increase/decrease automatically.

yes.
as its name simplicity. what are you trying to ask i dont get it. if you restore with apps+data you will restore back all setting in your apps.
