I've tried several and what I ended up doing is just using the power management widget (stock Android) on my main screen and just turning off wifi, GPS, dimming etc myself when not needed. Most of the apps are made for phones and I found it somewhat annoying when their "auto" functions did something to interfere with my current use of my tablet. Note to myself... KISS... In trying to use the apps I ended up wasting a lot of time with not better results. My opinion only of course! Some will certainly disagree...

Juice defender is pretty good. Has plenty of options, but some of them are available only on the paid version.

I use the juice defender with wifi. Very outstanding.

For screen dimming, try RootDim or ScreenDim. They actually allow you to dim the screen below the minimum brightness level. Very useful for reading in dark rooms.

Thanks for all the replies.

I used Autostarts (needs root; I actually built it myself from the free GPL source and didn't buy it) to disable all sorts of processes that were starting on boot and on other occasions. I don't know if it helped with battery life, but it might have.

I also ran a script to kill Google Maps' Latitude background tracking process. See the last script in my post here. (And for more advanced users, and perhaps not on all devices, one can run my Google Maps network fix wakelock killer. See my post.)

Another thing I do is to use my PerApp to set a max CPU speed for games which don't need much CPU speed (this function of PerApp needs root). Games tend to need mainly GPU speed, and so on devices with good GPUs, you may be able to limit CPU speed without noticeable of performance, but presumably saving some battery life. The savings will be modest, since if the system thinks the CPU is being underused, it will slow it down anyway.

If you have a rooted Galaxy S2/S3/Note/7.7, you can use my Galactic Night to turn off some of the display colors and save battery this way.
