Terrible battery life, and battery only shows increments of 10? HELP:/

All of a sudden my battery life is terrible. My phone is dying in within an hour with no use and it is getting very hot while the screen is off. I have tried resetting it a few times nothing works. I have not changed a thing on the phone. This is very sudden
 
This happened to me once, my phone wasn't going to sleep. A battery pull solved the problem right away for me.

Try *#*#4636#*#* from your dialer and look at the battery history, it will tell you how much time your phone has spent not sleeping
 
I experienced this once too, only it was due to an app I was using. (The follow me feature in weatherbug) I remembered that I had recently tried it and so went back & turned that setting off. Solved my problem.

Certain apps - especially ones that use gps as always on. Will kill battery quickly and cause battery to get very warm.

I think your battery might actually be broken. You should probably buy a new one.
 
Things I've noticed on the battery:

#1 battery drain is display. Dropping the display to 25%ish brightness makes a massive difference in battery time while having a minimal impact on visuals unless you're in sunlight.

Live wallpaper battery usage in my experience has been minimal. What is more important than type of wallpaper is the color of it. Darker backgrounds in apps/home screens seem to use less battery than lighter ones. This is especially true when browsing the web on the phone. flipping through a lot of white-background pages burns through the battery a lot faster than dark ones in my experience.

Personally I only use the data when the phone isn't idle. So I set the phone to turn off data after 30 minutes when idle during the day and after 15 minutes when idle at night. I don't know if you can configure it this much in 2.1, but I am on Froyo.

constantly updating widgets burn through the battery because they keep using your data connection. This can be particularly bad if you are in a bad reception area as 1x connections suck up massive amounts of battery.

going into a bad reception area? turn on airplane mode.

Normally I pull my phone off the charger when I get up at 7am and put it on when I go to bed, which can be anywhere between 10pm and 2am. The lowest my battery normally gets is 40-50% by 2am, and my usage varies a LOT.

Biggest thing to remember is that like the man said, you can't use the thing constantly for 8 hours and expect it to last you 2 days on a single unextended battery. Tests have shown this phone has the best battery use on the market for droids.
 
My solution was simple.

First: no matter what people say, ATK was a godsend for me. I configured it to kill only the apps I never use. Which is a lot. For some reason these bloatware apps decide to fire up and I would love to be rid of them. But for now I endure them because I am not savvy enough for the root experience. ATK set on every thirty minutes and aggressive mode, with a proper ignore list will extend the life of your battery immensely. For me, I get 10-12 hours instead of 5-6. Before ATK my batter was near dead at lunch time.

2: Widgets - kill all active widgets you don't use. The barer the home screens the better.

3: Turn the phone OFF when you put it on the charger at night. What I hear is you only need a minute or two, but I just practice shutting it down when it goes on the charger. I noticed a bump in battery life when powering down the phone.

My battery life got better with 2.2 Froyo as well. I assume this will be reported widely when Froyo is officially released.
