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.

I don't know if it's the ROM itself, the battery or any other problem but every time my phone dies & I put it on the charge for a couple of minutes, I turn it back on & the battery level jumps up about 30%. What should I do about this?
i.e. I'm not running on the stock ROM.
It might have to do with the Sensation's issue with reporting battery levels accurately--sort of like how your phone stays at 100% for several hours before finally dropping down.
Is it a stock battery or large capicity version, if the larger version there is an issue with some roms or phones recognising the battery correctly
It's the stock battery that came with the phone...do I have to calibrate the battery?
One thing you could try is charging the battery to 100%, then booting into clockworkmod recovery, go to advanced, and click wipe battery stats. Then once the phone boots just unplug it and let it drain from normal use, and charge it to a hundred another 2-3 times and that should get the battery back on track. I did this after changing roms and it worked for me
may some of the wipe battery options can help you
hi all
i got my new w8 last week and i did not charge it for 8 hours ...
when i got it i straight
-root it
-install a new rom
-and bring it out
-all in 40mins or so
is it a factor?
cause now my battery only last 4 hours before going to 0%
while my sister's w8 (same model ) have 60% battery after 5 hours .ck ..
really scared man cause 4hours battery life is unusable
even in stock it's still draining ...
specs -
w8
stock kernel / rom
will buying a new battery help?
Just recalibrate it. Turn it off and charge 'till full, boot into recovery and wipe battery stats, turn the phone back on and use it until it turns off by itself.
Try calibrating the battery... but I must also add that I flashed some ROMs and when I restored the backup of my original ROM, the battery life was absolutely horrible and the phone kept overheating. I flashed MIUI and now it's like a new battery again.
there are some free battery calibration apps in market too. some latest works too.
battery calibration is very god
Very unlikely that you did any permanent damage. But I would be sure to do a few full charge cycles. As in charge to 100% and leave it plugged in for a while, and then allow to drain all the way to shut down.
I just got a battery from etradesupply and now im having some issues with charging and fast drain. The battery will charge like normal up to 100% but if i power the phone off it will start charging for another 15 mins before full. After it's full and i power up it will show 85-90%. Ive done this cycle about 5 times. The battery also drains the first 10% in about 10mins after i unplug it then it will slow down. Just strange that even with these problems the battery life is about the same if not a bit better than the old battery. Im rooted running 5.0.1. I might try a fresh factory install when i have time. Anyone have suggestions before i try that?
bump...any ideas?

I'd say try to wipe everything on your device and flash the stock factory image first and see how it goes to rule out a software issue. If it still does not help then should be the battery.

When the battery first reaches 100% it's actually not done charging yet, it takes about 30mins afterwards before the juice stops flowing. If you unplug during that time it is normal for the battery to drop to show you the true charge level. Could that be what's happening here?
Try keeping it plugged in over night and then the next day it shouldn't drop by more then 1 or 2% (trickle charge kicks in around there).
