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.

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.

Ok, so I've been experiencing this for the past few weeks now, and I'm getting sick of it. I plug up my phone to charge it overnight, or just to charge it when I know I will be in a place for a while. After a while, the phones battery will say 100%. But when I take the charger out, the battery isn't fully charged. It IMMEDIATELY jumps down to around 40% - 70%. I can get it fully charged after unplugging and replugging the charger in, sometimes numerous times of unplugging and replugging. Also, my battery has died on numerous occasions on between 10% - 15%. I calibrated my battery the first day I got it (as a replacement) and got decent juice from it, a noticeable improvement from the old battery. Am I the only one experiencing these issues? Is there a fix for it???
*NOTE* I'm on my 2nd battery (replacement) and this is also a replacement phone. Also running GummyCharged 1.8 GBE on EP1Q, RFS, w/Minimal Gummy theme, if that matters. Also, its not just my phone, my wifes Charge phone has the same setup and it does it also. So it may just be something wrong Gingerbreak. Never did it on FroYo. Gonna Odin back to FroYo and report back.

This is because you cannot leave the phone plugged in to charge for an extended period of time. Once the battery reaches 100%, it stops charging. It will start charging again later, after the percentage goes down to a certain set level. This is why you have the huge initial drop-off after taking it off the charger. If you want to leave the phone plugged in for an extended period of time, turn it off and plug it in to allow it to charge, then it won't discharge as quickly. Otherwise, this is normal behavior for all android phones, and trying to make it so that the phone stays at 100% full charge is bad for both the battery and phone.
I've been having some strange problems. My phone will die with between 4-8 percent battery left. I can turn it back on and once it drops another percent or two it will turn off again. I have calibrated it and my battery life is good but this is a strange issue. Upgrading to rc2 today.

I have the exact same problem. It will just go from 50% to 100% in a second and then unplug and plug back in to make it work. i haven't been able to figure it out either. 2nd phone and 2nd battery as well with same issue. I guess it has to do with my habits somehow.

I believe the use case he is suggesting is a little different than what you are describing. When the phone is plugged in at say 12%, it charges for a while and gets to say 63%. At that point it jumps to 100% immediately. The phone must then be unplugged from the charger and re-plugged in and then it will continue properly to 100%.
Hopefully that is a little clearer.
I mean, usually I turn it off to charge. And I have that No Moar Powah app installed. So I set it to reboot at 100%, it does and when I take the charger out, it immediately drops to between said percentages. almost like clockwork. Very annoying. I understand what u mean Imnuts, but my Vibrant, HD2, or others never experienced this issue. Also, my first Charge, would keep a charge if I left it on the charger once it hit 100%. Maybe an issue with the charger itself? A Verizon rep told me to bring in the charger itself if the issue persists.

Hmm i have the opposite of that problem every time i unplug my phone from charging overnight the battery meter would always read 100% never below that.
Also does anyone know which battery meter i should follow for battery calibration? The battery meter in the status bar, the battery level in system settings/about phone/status, the battery percentage at the lock screen or the battery meter on the screen when the phones off? They're all giving me different readings for some odd reason.
Sometimes I get that too, but for the most part, its the false readings from the lockscreen, and the about phone settings. I may send off for a new phone, run stock for a few days to calibrate my battery then root on a full charge.

Well I went back to FroYo GummyCharged v1.9 and lo and behold, the charging issues VANISHED. Charged my phone overnight last night and when I removed the charger, 100%. No drop immediately back down to 56% or some weird number. Maybe its a Gingerbreak leak issue. I've noticed that it only happens to my phone on Gingerbread. Also must mention, my wifes phone does it also. She's on Gingerbread. She complains that I broke her phone lol.

The mis-information in this thread regarding Li-ion batteries is getting out of hand.
I think many of us are thinking about ni-cad batteries in which all the "bad" things we are talking about in this thread apply.
for a Li-Ion Battery, there is no "memory" effect. this means you can charge it at any point during the discharge phase. You also do not need to allow the battery to drain fully and charge to full to "condition" the battery. Li-Ion batteries can be charged at any point up to any point (from 30% to 70%, then 50% to 90%) and it will not effect the batteries performance.
Li-Batteries also do not suffer from overcharging. The charging circuits in cell phones will charge the battery until it is full, and then trickle charge from then on. And because Li-ion batteries do not have memories, this type of charging will not effect performance.
Li-Ion batteries can only be charged a finite number of times. However, the number of times does not translate to the number of times you happen to plug it in. The batteries have a rated number of "charge cycles", this is when the power from the battery has been exhausted and then re-filled. If you always charge your battery at 50% - 100% then every 2 charges you are using 1 full charge cycle. The batteries in the charge are 1600mAh and have approx 500 charge cycles. if you discharged and charged your phone from 0 to 100% every day, your battery would last 500 days before it would start to suffer from poor performance.
the OP in this thread is having software related issues related to the phone mis-representing the correct charge level of the battery, and then stopping the charge cycle prematurely.
Remember, it is perfectly OK, and expected of you to charge your battery as many times as you need to. Keep the thing on the charger any chance you get, it is not going to hurt it, its designed to be used that way. This is why Li-Ion took over as the battery tech of choice compared to Ni-cad.

This coming from a person WHO KNOWS WHAT HE IS TALKING ABOUT is very beneficial to us. Knowing that there is no way to actually "condition" a Li-Ion battery means that us who are actually suffer from poor battery life either have defective units or defective batteries. I hear of this miraculous 2 day battery life, yet I struggle to get thru a full 7 or 8 hrs with moderate usage. And this is a replacement unit AND battery. None of my other phones had that issue of immediately droping percentages like that, so I figured it was a software issue, that's why I went back to FroYo to test it out. Seems I was right. Gingerbread has a software issue that keeps the battery on some phones from reaching a full charge. Also my phone would be boiling hot during the charging process. Since reverting back, I've had no issues. Thanks for the insight. Coning from a knowledgeable source, it means a lot. Thanks!!!

Ok , so every time I flash a rom I calibrate my battery. But I noticed the battery last the longest after the first charge of calibrating. When I calibrate, I kill the battery, pull the battery, put it back in and wipe bat stats. I then leave my phone to charge overnight (6hrs). At that point, turn the phone on and off, charge it again while off until it shows 100% (usually about another 10-15min). The battery last about 2 days with moderate use. I wait for the battery to die before I charge it again. But this time, I charge it the normal way. I don't go the full 6hrs, I just wait until it shows 100% (usually 2-3hrs max) and unplug the charger. But on this charge, the phone only last about a day. So my question is, what could be making this difference in battery life? Any chance these phones really need over night charging (6hrs) to get maximum battery life?
btw, I'm running Valhalla final.
From my understanding battery life takes a few days to settle in especially after flashing a new ROM

I would think that letting it soak in would see battery life only get better not get worse and then start improving again. I'm gonna do more overnight charging and compare it to just charging to 100% and unplugging the charger. And see if it truly makes a difference.

Do i let the phone shut off from the battery reaching 0%, then charge it to 100% and be on my merry way?
I've read multiple theories, but I think u should take it down out of the box, then shut off and charge to full...I remember ASUS recommending that to a media outlet when the Transformer 300 came out a few weeks ago...so that is what I am going to do when I get mine.
Thats exactly what I did, I let mine completely die and then charged to 100%.
Be careful with how you charge the phone, rather with how low you let it get.
Depending on how technical you want to get about it purposefully letting a battery drop to absolute zero can cause some odd chemical reactions that while not immediately evident can some times shorten battery life.
I would recommend taking it out of the box and using it until it is low but not dead. Maybe 10 or so percent and then either turn it off and charge it or leave it on and charge it just do not pull the plug on the charger until it is at 100%.

This.
Full battery cycles are not good for long term life of Li ion batteries.
Also, its unlikely, but occasionally happens where discharging the battery to shutoff will render the battery unable to take a charge. The safety circuit on the battery is supposed to prevent this, but its not failsafe. I've seen more than a few reports on previous HTC devices where this happened. And since the battery on the One X is not easily replaced, the result can be disastrous.
The battery meters on phones are not very accurate in the best of circumstances. No need to drain to shutoff, 10 or 20% is fine. No value added to draining to shutoff, and the consequences can be very bad.
Drain to 10% or even 20%, charge to full, repeat 2-3 times. This is done just to calibrate the battery meter on the phone. Its a misconception that you can somehow increase battery life by "conditioning" the battery. But modern Li ion batteries do not suffer from memory effects, and conditioning only works for older tech NiCad batteries.
I do the same thing for all of my phones.
1. Activate and mess the heck out of it until it dies completely.
2. Charge it up to 100%
3. Mess the heck out of it again until it dies completely.
4. Charge it up to 100%
5. Mess the heck out of it again until it dies completely.
6. Charge it up to 100%
Then use it normally

Don't worry about letting the phone die and charging it up to 100%.

Mine came dead too. Charged it to 100% and now been using it and so far have 36% on 3h 9m on battery.
Screen at 84%
Does the battery life get better? Because it seems to be draining rather quick. Even though I have screen brightness less than half.

Don't worry about letting the phone die and charging it up to 100%.
These batteries don't have a "memory" like older phones

@Maroon Mushroom, Correct these lithium batteries dont have memory effect, but over discharging them will shorten its life.
I dont want to sound like an expert, but discharging the battery until it dies is not recommended. It will affect battery life/performance.
A couple of good references here: http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries

Ya, we use Lithium Ion (Li-Ion) batteries now which dont have a memory. The older Lithium Polymer (Li-Pol) batteries did have a memory and needed a certain charge method to get the longes life cycle out of it.
Awesome, thanks everyone
I turned it off at 20% and wen't to go buy my MicroSIM (ugh...) cant wait to play with it tomorrow
Why would you buy it? Pretty sure they would give one to you for free

bought it off Kijiji
It's offered by Rogers, but i'm on Telus
Hmm, i hate the idea of letting it die completely. But what i've always done is turned everything on and ran it through a low-powered usb source so it has a charge but the battery is still draining. So even if the battery runs dead it has power via USB plug [make sense?]. Usually having everything on [i do mean everything] and downloading a torrent so the internet is constantly under use. Then again i'm not sure how the One X will work out for this, but thats what i'm planning .
guys its lithium...u cant drain it to 0...even when android shuts down your at around 3.6volts. thats definetly not 0volts. no memory and android wont let you ruin your battery...so charge however whenever.
im qualified in lead acid. ni cad. nimh and lithium batteries. trust me..u cant hurt it unless you short it! !

Hi everyone I have a problem.
When I charge my battery it charges normally to 70 % after that it takes about 3 to 4 hours to charge till it reaches 100 % but if I reboot my device when it's charged to about 75% the Battery is suddenly fully charged.
I have tried to calibrated it but it didn't help.
I have this problem on every rom. What can the cause of the problem be.
It used to charge normally at first when I bought.
I have my desire s for one year now.
My device is rooted via revolutionary and s-off.
Thanks in advance.

Have a look at your battery for any swelling or signs of damage on the battery, it is possible that your battery is shot.
Re: battery...
Could it be that with the reboot,
device wipes its battery stats and looses the info?
(Or is it happening only during flash)
my phone has that same symptoms, but it happens mainly
, when i flash a rom, forgetting fully charge the battery before- after reboot it indicates full charge..
Edit: according to amidabuddha, htc has implemented safety switch in to charging procedure,
, when the load reaches certain level- it slows down
Then begins to indicate ' fully loaded' before
It realy gets to it- that is suposed to lengthen live of the battery,
but three to four hours sounds unusual...
Edit 2. When during charging battery gets to hot, charging stops as well...
Me too, charging from 0-70% needs 1,5-2 hours then 70-95% needs 4 hours, 95-100% just needs couple minutes, Idk why this happens, the battery stat says health...
When in the middle of charging I reboot the device, the level rises up anomaly, ex. The device is charging, and the level is 12 and I reboot, when I get back to homescreen it says 45%..
Also, the led changes from orange to yellow not when the level on fully charged, usually on the 90%.. my device is almost 2 year old

duh, it's because nothing is draining the battery while phone is shut down.

no, there is much difference in time.
From my experience, this behaviour is due to battery age. It started happening after about a year for me. I bought a new battery and the problem went away.
But I never had any real problems as a result of the slow charging of the old battery. If you recharge overnight, then it will have sufficient time to fully charge.
Based on what I now know, I wouldn't replace the battery until it stops holding its charge.
