To help with Battery Life you can do these steps exactly:
1) Turn your device ON and Charge the device for 8 hours or more
2) Unplug the device and Turn the phone OFF and charge for 1 hour
3) Unplug the device Turn ON wait 2 minutes and Turn OFF and charge for another hour Your battery life should almost double, I tested this on my pops evo and my epic...MAJOR DIFFERENCE
After installing a new Kernel it is recommended tat you recalibrate our battery to get the most life out of your battery. I suggest using Phoenix kernel but your a grown man[or woman] choose your kernel
Hope this helps
Thx to bigdbag for these additional steps

My god. I was highly skeptical of this but I tried a quick version of the instructions.
I did the following:
1. Charge to 100% while phone = ON
2. Once at 100%, unplug charger and turn phone OFF
3. Plug in charger for 5 minutes while phone = OFF
4. Unplug charger and turn phone ON
5. Leave phone ON for 5 minutes
6. Plug in charger for 5 minutes while phone = OFF
and the results... are miraculous. I'm running Phoenix Kernel v.1.43 and stock rom w/ drm removed.

Trick trick trick trickle charge Battery is in fast charge mode when it begins charging from a certain percentage (although slow). When the charge is in the 90's and you unplug and plug it back in it trickle charges to completion. This does indeed work. Works best in my opinion when you do this after you let the battery completely drain, plug in, recovery mode, wipe battery stats and then turn on.
And then do what you stated above.
Yes!!!!!!!!
Totally gonna do this since my battery seems to be on the down side compared to everyone else's. :]

i also reccomend an external battery charger that u place the battery into. no need for the trick. Ive used this trick before i got the external charger and yes it does work very well!
+1 on the ext charger. I have two batt. If I charge with the phone... one- goes from 100 to 97 withing sec from when I unplug it and two- it doesn't last as long. Using the charge and switching out the batts. Stays at 100 for a while and it will last forever too.

I noticed this as well, so when my indicator LED turns blue and it says 100%, I unplug, then immediately plug back in until blue.. lather rinse repeat.. after about 3 or 4 times it finally stays at 100% when unplugged..
That being said, I'm gonna have to try to find an external charger and another battery...
My local sprint store sells a charger with extra battery for $49.99. Its an external charger that fits in your pocket. With charging cord of course.

tried this, doesnt' seem to work for me. I unplugged, turned phone off, and charged, but phone said fully charged after like 15 minutes, I assume once it says 100% on the green battery that shows up when phone is off that I shouldn't just let it sit there? its not charging at that point anymore is it?
then i unplugged, turned on phone, waited 2 minutes, turned off, charged again, 15 minutes or so it was fully charged again.
This reminds me of the chargobics that some ppl did on their evo to get better battery life....never really helped me.

So what you're suggesting (re: recovery/battery stats) is the following:
1. use the phone until the battery completely dies.
2. plug the phone in
3. boot into recovery (clockwork ?)
4. wipe battery stats
5. turn the phone on
6. do the 'plug me in' dance after it's fully charged
What if the battery is fully charged and you wipe the battery stats ?
idk i think i used to do something similar on my Hero and even back on my (WinMo) Mogul and Touch Pro and never really got much out of it......
However, today I did this and I swear I'm getting great battery life today. Have never gotten past 12 hours and I'm currently sitting at about 40% left at 12 hours. Could be the placebo effect but we'll see..... even played some angry birds today.

FTW!!!
Took 11 days to get here, but worth EVERY penny. I never need to worry about to battery life anymore. Hell, now that I charge my batteries using the external charger, I get atleast 8-10 hours with constant use, and my battery doesn't drop from 100 right away. I never get to the 3rd battery by the end of the day and thats with a 18 hour day unplugged. Worth it.
I have noticed some weirdness with the battery. I looked at the juiceplotter graph after the battery had been left charging all night, and it would charge to 100 and then over th course of half an hour drop down to 95% or so and then recharge up to 100 over and over and over again. I have taken it off the charger sometimes and the battery has gone from 100% to 96 % within a couple minutes and other times it stays at 100% for over an hour. It was a matter of luck as to when I pulled my phone off I guess, when it was really at 100% or really at 95-97% or anywhere inbetween.
Gonna try this PITA method of charging. Hope it works, but damn is it inconvenient.
The external battery charger is the way to go. i have also noticed when i rarely charge from the phone that it sometimes wont stay at 100 but for a minute then drop to 97. i get 55 hours to one battery with moderate usage.
This didnt really do anything. Unplugged from my charger at 1:50pm, its been exactly 2 hours and its at 77%. Mostly my phone was in my pocket, and I did very light browsing over 3g (maybe 10 minutes).
I'm on Latest Epic Experience with Mixup Kernel. And I don't have OC widget or Setcpu.

Try running the same setup with phoenix 1.43 kernel. Still super snappy and way better battery then mix up.
I'm also using external charger, 30+hrs with screen on for 6hrs

Is it really that much better? If so, what causes it to be better on battery life? I am getting great battery life using the mixup kernel because I have juicedefender and setcpu working hard to conserve battery life. Would Phoenix make a difference?
Just a FYI, Lithium-Ion batteries don't hold a memory like NiCad batteries did. It is also NOT good to drain them all the way down.
read and follow directions

Do I have to wipe anything?
Is this normal. I did try and do a search in my defence.
Yes. It is like that by design. It stops charging at around 95-98%. Its to prevent you from overcharging the battery.

This is a known issue. You can try and reset battery stats in cwm when your battery is charged and/or emptied. It works for some and not for others. I haven't noticed my battery lasting any less when my battery doesn't "charge" past 97%
There have been some discussion on this. I get about 97% myself. From what I've read you may get full charge if you let it drain all the way. I don't do that myself. Very happy with battery life as is.
I used to get 100% before I switched to the Vegan rom.

Either let it drain until it shuts off a few times and then charge it all the way up or if that doesn't work, use CWM to delete the battery stats when it's at 95% (full, with a GREEN light - not charging, with a red light) and then let it drain until it shuts off on it's own.
I did this a long time ago (delete the stats) and it's been perfect since. Charges to 100% and does indeed show battery at almost empty before it shuts off.
Good Luck.
Still no go here but it can get tom 96%... lol
I am sitting a 98% with VEGAn.
I am now having an issue where u can use the device, then I turn it off, and
turn it on the next morning and see about 5 to 10% of my battery was drained.
Confirmed Fix
Confirmed fix for me on Vegan 5.1. Letting battery drain down to zero and shutoff the tablet... reached 100% on next charge. Now the indicator charges to 100% every time.
tried this and still no luck . still get to 95-6% bugger
Vegan here..this is how I fixed it:
1) Drain it till it shuts off, try restarting it a few time to make sure its dead.
2) Once dead, plug it in, boot into clockworkx, and reset battery status (do this quickly)
3) restart, and leave plugged in idling till fully charged
4) use and enjoy a accurate battery level!!

You have to remember that in order to install some apps out there, you have to give them permission to use the internet and to interact with your device autonomously. I have found a few apps that were pulling my tablet out of sleep mode and turning on the wireless to download ads or other updates, and that (along with the length of time to shut back down) was affecting my battery life.
I would say to go back and review what you've installed, and to also check your screen timeout settings. Just doing that saved me quite a bit of overnight battery loss.

Last night I left the house with about 40% left on my battery. By the time I went home, my Sensation was completely drained. This was within 3 hours, which should not drain it to 0%, especially since it was asleep most of the time.
When I got home and I plugged it in, I booted it up and surprisingly, it booted up with 42%. Before plugging in it had no power left, and the phone wouldn't boot at all. I wiped my battery stats yesterday morning too, after charging it to 100% for a few hours.
Seems like my battery stats are VERY wrong right now, and I just wiped it again after charging it to 100% and leaving it there for a while. Does anyone else have this problem? I know some people are having random stats popping up here and there, but this still had 30% juice left before it just died out. Never happened before. I was able to nearly fully drain it just 3 days ago too (100-5%).
Charge to full, wipe again, and drain to about 5%. Charge full and repeat. It usually takes a few cycles to correct battery stats.

I'd also recommend this application from the market for battery calibration, although you need root.

Alright, thanks, I'll try that. Hopefully it gives me an accurate reading
Hi all,
There's this problem with my phone that everytime I charge it, it takes an elongated time to do so. This issue first emerged when I was on stock GB after a minor OTA update which added the power saver toggle to the quick settings menu..The problem is that it takes about 4-5 hours to fully charge the phone, and if I rebooted in the middle of charging when it's about 70% or 80%, it suddenly shows that the phone is fully charged, and the indicator becomes green! But afterwards the battery drains as quickly!
Now I have S-Off and using ARHD 6.6.3 ROM, but it seems the problem persists ..I wiped battery stats as soon as I flashed the ROM as well..Although it's not a problem I cannot live with, it's annoying enough when it happens.
Can someone please help me? And suggest me what to do?

its common thing...the battery calibration is not proper that's all...
also you need to wipe stats once you charge your phone to 100%
then battery will try to calibrate ...and after 3-4 full complete cycles (100-0 and 0-100)
the battery will settle..
the battery drain will be there ...whenever you flash a rom or flash a kernel....battery only settles atleast after 2 full cycles
EDIT: also download currentwidget from market..as the name says its a widget..so you will see it in widgets once you installed it...this will give you more proper reading of battery...when you plug your phone to charge...and when current widget reads 0mah then your battery is charged completely...(it might take a long time to read 0mah...but charge it until you see 0mah)..then wipe the battery stats...so after this battery calibration will be proper
Also the sudden jump of battery percentage is due to improper battery calibration
so dont worry you got no problem
So
I read somewhere that you are not supposed to let the phone go to zero because it could cause your phone to not power back on anymore..is this fact. I couldn't find where I read it to back and read again. Mine has been doing some weird things as well...the led turns green before it is 100% and it goes from 100% and drops to like 89% out of no where.

when i meant 100%-0% means until your phone turns off due to less power..it might not(or won't be) be 0% then
as i told you that kind of jumps are common ...in my case it went to 60% to 100% when i rebooted ...also the dropping used to be in large scale too

Thanks mate! I will try this out! cheers!
Not sure what's happening with my phone, but after removing the plug on my fully charged phone, I will let my phone sit idle for about 10 mins, when I go wake the screen, I see that I've already lost 3% of battery capacity.
The weird part is after this initial 3% is gone, my battery will drain normally. Does this mean I need to calibrate my battery? Is there anyway to do this without damaging it?
It means you need to get a new hobby... seriously, why do you care if it changes nothing what so ever. In order to fix this, you should try not checking your battery percentage every 2 minutes. On the upside, this will probably give you another half hour of battery life as well.(damn a change of attitude would fix like 90% of problems on this site)
On a more serious note, it's likely just because your phone doesn't keep charging when it hits full charge, it stops charging in order to not kill your battery, and lets it drain to like 90% at which point it will charge back up to 100%, so it may be at any point in between when you disconnect it. Even if it is truly at 100% when you disconnect the charger, the measurements may not be completely accurate when approaching 100%, so it is likely, that could make it drop faster at first. You need to do nothing in order to fix this, seriously don't mess with it.

Are you running stock or custom kernel and any custom ROM? Ive noticed this sometimes too but that's because the phone, when unplugged is running services to start phone on battery power versus the cord/wall charger. Check logcats to see what happens when phone unplugged to see what may be happening when phone starts on battery.
I think you are worrying about it a little too much. It could be searching for service (which drains a lot of battery), starting services as someone previously said, heat is horrible for a battery, anything. If the drain is normal after that who knows it could be the ROM you are on, battery percentage not being reported correctly.
Not worth an RMA by any means. Reset battery stats in recovery and see how that works out for you.
Bear in mind, these batteries are cell batteries, a user who plugs their phone in every time the battery hits 50%, is going to notice over a period of time the time it takes to go from 100% to 50% is shorter and shorter, and suddenly, 49%-0 holds a better charge. If you're constantly charging your phone, you'll wear those cells of your battery down. This is where the "hoax" of always letting your battery drain to 0% when you get it to "maximize" battery potential came from.
