Turn off all radios when not in use (gps, Bluetooth, wifi, data, 4g). Use a widget (default or app like Switchpro) to quickly turn them on and off. The radios draw power even if not in use. Be sure to use WiFi over 3G when you can.

Stop using live wallpapers - I love them, but they are really only good for showing off due to their battery drain.

Set your screen timeout to something that fits you - This will prevent your phone from staying on when you don’t manually turn off the screen (which you should).

Everyone has that issue where the first ten percent go the fastest.

This is due to two things. One is that these types of batteries stop charging once they get to 100% to prevent damage, and begin charging again at 90%. This means that you could potentially unplug your seemingly fully charged phone at 90% actual charge. The second is below

Use the trick described in this thread, it works.

My idea behind how often you should do it is once a month, if you flash a new ROM, or if you stop noticing the benefits.

This is the calibration technique recommended by HTC themselves. Check it out!

Make sure your phone sleeps - I'm sure you have all heard around that your phone isn't "sleeping".

This is referring to the phone's "awake" time, hence the name. When you go to menu>settings>about phone>battery, you can compare the two numbers, "up time" vs. "awake time." Generally, up time refers to the amount of time since the last reboot. The "awake time" is how long the screen has been active. The problem is, a lot of the time, due to the endless possibilities of inconsistencies between apps/ROMs/kernels/phones, the phone will not go to "sleep", drawing power proportionate to the screen being in use when it reality the phone is sitting idle.

If you compare these numbers, and they are the same, or if you note the difference, turn off the screen for a minute, then re-check and they are the same, then your phone is not sleeping.

One solution is to reboot.

Usually, SystemPanel will show an app that has gone "rouge" and is keeping your phone awake.

Uninstall applications/reinstalling them slowly, checking after every install to see what is causing it is one tedious but surefire solution.

Lastly, follow these steps that I have discovered almost always work.

Reboot phone.

Instantly upon reboot, as soon as you gain control, open up some type of monitor/taskkiller

"kill all" tasks on startup; about 5 times in quick succession should do the trick.

Turn off the screen and leave it for about five minutes.

Check the up time v. awake time and see if they are the same.

If they are, repeat steps 1-5. If they are different, you are good.

Use Juice Defender - Basically it controls your data for you to maximize life. Learn more from my review of Juice Defender.

Task killers used to be the shiz, but no longer.

Here is the ultimate, in depth, graphically assisted, explanation by the famous Fresh ROM's chef, Flipz. In short, they aren't needed (and can do more harm than good).

A good alternative is the application SystemPanel Pro. It has a free version, but I highly reccomend purchasing the paid app. It basically monitors everything going on with your phone's usage both in real time an in terms of usage history. If your battery is draining fast, it tells you what app was doing it, how much it was doing it, and allows you to stop it.

Try out custom kernels - In the Android Development section of the forums, you can see all of the different kernels being developed. These allow for all kinds of modifications like underclocking the CPU and undervolting, both of which save battery. Here is a great guide to custom kernel's by mroneeyedboh.

Use SetCPU in compliance with whatever your custom kernel allows.

This site will explain the basics of SetCPU: http://www.pokedev.com/setcpu/

-Profiles from SetCPU should usually involve these for battery life optimization:

-Screen off at the minimum clock speed for both, with the max raised on level if sluggishness is apparent

-A temperature greater than “X”

-General power related profiles that lower cpu speed at lower battery levels

◄●Notes●►

Some apps or processes begin to run at startup and keep the phone awake. These apps are not detected by things like spare parts or system panel, unless sometimes represented in the "system" process, in which case its usage will be unusually high.

This shouldn't take more than three repeats, and if it does, you need to factory reset, and slowly add apps back to see what's causing the problem.

When it comes to actually "calibrating" one's battery, there are a couple of methods floating around. The method I first learned is to charge the phone all the way, boot into recovery immediately, and "wipe battery stats". Then reboot quickly, and run your phone all the way to death without charging it, then charge it all the way without interrupting it, and you should be good to go. Do this when changing ROMs/kernels for best results.

Big thanks to Biofall for the battery tips that you see her. Thanks dude.
