I would consider that great battery life, depending on how much screen on time you had...

Over 20 hours, yes. How long was your screen on? What ROM, kernel, radio?

Just to see how long I could go without recharging--I often do it every other night--I went three days on CM7.2-RC1. Main use: Words with Friends (one-hour updates), a few sites (HuffPost, Reddit, Drudge, Slate), constant 1Weather (one-hour updates), GPS always on, Wi-Fi only at home, BT only about forty minutes daily (two twenty-minute trips in the car). I usually have it on at 5:30 a.m. and turn it off at about 10 p.m. every weekday.

Virgin post; apologies if I erred here.

Here's another long bout without charging that might give you details about my use.

Missing information from previous post:
Kernel: Faux123's 023 (the only one that seems to let me use WWF seamlessly)
Mod: Cyanogen 7.2-RC1
Launcher: ADW (stock with CM7.2)
Most everything else is the "standard" with the mod.

That's very little screen time. I have far fewer wakelocks but my screen is on about half my walking day. No polling at all. No GPS or Bluetooth and WiFi only at home. Airplane mode on the subway. Autosyncing Google services and Facebook contacts though. Auto-brightness which is typically set very low. I can barely make it through the day. The screen is a battery killer. Samsung phones can get away with a smaller capacity battery because of the AMOLED screen.

Not really. This depends. If you are a movie watcher, which displays a lot of blacks, then yes, you'll see increased battery life.
But for web pages with white pages, AMOLED's really suffer. Check out GSMArena's battery tests for the Galaxy Note for example. A 2500mah battery, lasting ~4 hours web browsing compared to an iPhone 4S which can last ~7 hours.
Obviously this isn't a fair comparison because of screen size etc. but bare in mind that the iPhone has 1100mah less then the Note.

Simply put:
AMOLED's better for blacks.
LCD's better for whites.

In other news, apparently the new kernel in the latest nightly has even better battery life. Anybody care to share?
