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?
I decided to try resetting the battery stats, charged the phone to 100%, then turned off the phone and plugged in the charger and now the green battery icon looks like it is about 90% full, but never goes to 100% (I've left it plugged in for 3 hours since). Any ideas?
Update: Full discharge and recharge seems to have done the trick!
Let the battery drain to zero. Plug in for a min then unplug to see where its at. If its at 1% charge it back to full and reset stats again...if it says something weird like 12% or more or less let it drain and die again until its at 1% then recharge and reset stats. Then let die completely before recharging

I've found that my phone won't charge all the way unless I'm using the wall charger or car charger that I got with the phone I had tried using a charger from one of my old phone's and it actually made the phone go into sync mode and still didn't charge it all the way sometimes even when it's plugged into the computer it wont charge all the way

Good Morning everybody!
I think I have a defective thunderbolt battery, sometimes when I pull my phone off the charger it drops to 95%. Funny thing this is not a everyday thing. Anybody having a similar problem like this? Sorry if this been discuss before. Have a bless day everybody...on my way to the office.
I have the same thing happen. There is something goofy with how the meter reports battery level. If you reboot your phone it drops even more.
Sent from my ADR6400L using XDA Premium App
Yea I notice that too. I seen my battery drop down 15 percent after rebooting. Is the battery defective? Or the phone is defective?
Bump charge it. Charge it all the way. Unplug, turn it off, then on, and keep charging.
Sent from my ADR6400L using XDA App
The phone/battery aren't defective. I have the extended battery so I never bump charge it, but he is right. Charge it up until your charging light goes green, unplug it and then turn it off. Once it shuts down, plug it back in and will now be orange. Charge it until it's green again. Sometimes it will take a few minutes, sometimes an hour. I'm also color blind so I can never tell whether that damned light is red/orange/green. >.<

charge ur batt. to 100%, then go into cwm and clear batt. stats, when u turn it back on it should b around 80-85% then charge all the way back full again and then u will b at full capacity

is this all the time we have to do, I have the extended battery and it doesnt drop and I read about clearing the batterystats.bin but is this something we always have to do when we charge the phone? when I use the standard stock battery it drops with no problem
I didn't have any issues until I wiped the battery stats and now, my battery is constantly inconsistent. I would not recommend doing it as it has nothing but a pain in my arse since.
Have tried "bumping it" which essentially means to charge it to 100%, restart it, then charge it back again from whatever it dropped to.. Mine initially was around 85ish.. After a few "bumps" it crept up to 90 or 91 and then wouldn't go any higher. I charged it back to 100% and decided to follow the advice from another article which said to let it deplete to 0%.. In doing that, surprisingly it "froze" in a couple of places, I don't recall the 1st % but the 2nd % was definitely at the 28% mark. It literally sat there for a good 2+ hours with screen on max and didn't go down. Eventually it went down to 1% and I charged it back to 100%.
Issues still remain, wondering if I should've let it completely die out and force itself off?
Lesson: DO NOT MESS WITH BATTERY STATS with CW.

Where do I get into CWM, to do this?
Thanks for your help everybody! I'm sorry if this is a dumb question...what is CWM? My device is stock.
CWM = Clockwork Mod.. Goto Market, download ROM manager, then you can flash CWM. Not sure if that'll do you any good if you're not rooted though.
why when I reboot my phone like 15% of the battery life drops I love this damn phone man...i cant put it down while im at work
The battery reading after reboot is wierd.
Yesterday I was at 51% and draining are at a pretty steady rate like normal. After rebooting, it showed 41% but then it say at 41% for AWHILE.. after like an hour, it read 40% and started discharging at the normal rate.

Thanks for the repost, I had skimmed this thread earlier but don't recall it being so detailed. Seems like the moral of the story is that while "bump charging" works, it's not really recommended as it can reduce the overall life of the battery. Wonderful, now I regret ever messing with the battery stats at all, although I can't say for sure I didn't have this issue prior to doing so.
My OEM battery wouldn't hold a charge even after charging it all day... I took it to the VZ store and they replaced it for free...... I also just bought the larger 2750 mAh battery.... works great!
I'm trying to calibrate my NS (i9020T) because it seems like battery drains quite fast after frequent flashing ROMs. Last time I calibrated was about 4 months ago.
But the problem is that it won't charge beyond 99%. It used to charge up to 100% before if I leave the screen on.
But don't I need to get battery % to 100% (that's what calibration app says)..?
How can I get it back to 100% charge?
Thanks!

Not sure if it works ffor ns, but drain your battery, go to data/system and delete batterystat or something along those lines and reboot. Let it charge for awhile and it should go to 100% . If it works you don't need to calibrate anymore as that's how normal apps calibrate.

drain your battery, delete the batterystats.bin, reboot, then charge all the way. chances are is that you had to wait a bit longer for it to hit 100%. when i charge my phone to 100, sometimes it takes an hour to go from 99 to 100%. be patient, if that 1% is worth it. the more you play with your phone between 99 and 100%, the longer it will take.

I waited 5 hours but it was still at 99%. I had to leave home so I couldn't charge any longer...
So drain it first, delete batterystats.bin, and it should charge to 100%? Because the app I downloaded says, charge it to 100% then delete batterystats.bin.. etc.

you must had something running in the background. believe me, the different between 99 and 100 is almost non-existant
The last 10-20% trickles in. 5hours is way too long though. What does your voltz read bc you can have a full charge as far as voltz go but may be getting a faulty % reading on the charge.
If you use the apk make sure you don't power off or you will regenerate the battstat through normal process and then the app is pointless. Try charging overnight and see if you can get to 100%.
Fyi/beware draining your battery to 0 is not good. Some batteries and phones have a hard time getting through first boot when there is little to no charge in the battery. Whenever I use the calibration apk, I never go below 10%. Anything below that can cause some funk.
I drained it all the way and deleted batterystats.bin, charged it all the way back overnight, but it doesn't go over 99% for many hours. I stopped all the services I could possible (kept only the essentials)...

So it's simply misinterpretation of the battery that it doesn't read 100%?
Well, I started calibrating about an hour ago. I thought it shouldn't matter too much.

Yes your phone sometimes gets out of sync with its self and starts thinking that its fully charged or fully discharged when its not. The way I typically calibrate my battery is to turn it off and let it charge until it stops (this is easy to see since the screen lights up and the battery shown on the screen stops unfilling and refilling). I then unplug it and boot it up. Again, shut it down and plug it in and let it charge until it thinks its full. Again, turn it on this time letting it charge to what it thinks is full while on. Finally restart into CWM and use its too for wiping battery stats. After all that I also like to let it die before I plug it in again.

My 727 (AT&T) is rooted stock rom. The battery indicator gets 'stuck' a lot of the time. It happens in both a widget and the default battery indicator in the status line.. They will both show 100% and I know full well that they CAN'T be at 100% after sitting around all afternoon off the charger. I restart the phone and immediately it drops to 42% ...

what i suggest you do is calibrate the battery.
1 plug it in and charge it to 100%
2 turn off the phone and charge it until it says 100%
3 unplug and turn it on and leave it for 3min.
4 turn it off and plug it in and let it sit until it says 100% again
5 repeat step 3
6 unplug turn on the phone and use it until it hits 0% and turns off
7 plug in the phone and let it charge to 100%
now use as normal and after a few days your battery will read more accuratley and more importantly, will last longer. keep in mind your battery does lie to you but just use the phone and you'll start getting more out of it.
moving forward, charge whenever you can. Lithium ion batteries will last longer if they're charged often (like at 60%-40%).

Yeah, I even downloaded the utility that removes the battery life file, and creates a new one. I guess I need to try one of these procedures again.. I honestly think it is more to do with a bad application, no matter what the battery life meter should not 'hang', and if it does for more than a few minutes, then it should be able to recover by forcing a restart of the app... *sigh*...
This is a common issue with this phone. Look up "battery stuck at 100%" in Google and you'll find quite a few results. Supposedly it's an issue with certain chargers not giving out proper levels so it trips out some indicator chips in the battery and/or phone.
