Battery problem, try this.

Preparing...
With the phone in the on position.
Fully charge the battery with the phone on... (until the led turns green.)
Once the led turns green, unplug the charger until the led goes off.
After the led goes off, plug the charger back in. When the led turns green , power off the phone.
now.... with the phone fully powered off...
1. Unplug the charger.
2. Wait until led goes off.
3. Plug charger back in until the led turns green. When it turns green, unplug the charger again and go to step 1.
4. repeat steps 1 and 3, 10 times. This may take anywhere from 30 seconds to 30 mins per cycle. Typically only about 1 minute. though.
DO NOT DRAIN THE BATTERY. The goal is not to empty the battery and recharge like ni-cads (those have memory, these don't). These are lithiums, so we need to do the opposite...

And lets all sing the hokie pokie and shout

The cells were not charged evenly, so each cell holds different charges. So when you charge it, 1 cell may be 95% another 100 and 98 etc... so when you balance the cells, they function like they are suppose to.
this phone does not have a cell balancer built into it.

So charge, wait til its almost dead, charge again til full, then do the process w the phone off?

I'm sorry this guide doesn't really make much sense. the led won't be on if the phone is unplugged so how will I know if its on Orange or not? also is the phone on or off when I'm doing this?

changed the instructions on top, i suck at writing.

I suppose this might explain why sometimes my phone plunges to about 90% almost immediately after taking it off the charger, but then battery decreases at a "normal" rate after that?

So were reconditioning our batteries...

I'm 99.9% sure the battery is single cell...it wouldn't make sense to have a dual cell 3.7v LiPo unless you wanted heavy discharge.
I don't see how this will make any charge other than the phone not topping the battery off...which in that case an external charger would do a much better job is so.

I tried this and my battery has been holding steady at 100% with the screen off for the last five minutes so something worked.

So is this a one time thing to re-condition the battery or will we have to do this more then once

Woah, voodoo magic here. Any proof of this working.....

No proof yet. Take it or leave it.
It works for me. Test on your own. Seems pretty harmless to atleast try...

Ingesting.
I've heard of draining all the way and recharging a couple times but this is a new one lol..

That's true, won't hurt anything. WTF I'll give it a try, maybe get proven wrong and learn something too..

I gave this a try and I must say that it is working. Before I did this, as soon as I would take my phone off the charger it would immediately drop to 96%. Now as david279 said, it will actually stay on 100% for awhile and have better standby time. Good find joker, I do see a difference.
How did you find out about the cells not being charged evenly?

WOW...this actually works. This should be posted on other forums so ppl know about it.

I'm a battery nut... actually, i used lithiums in model RC airplanes all the time. Balancing is a must.
Maybe someone can build an app for this, to reboot cycle on and off the power?
Is that even possible?
Now if someone would like to shoot me a awsome working froyo 2.2 rom *** joke

Finally sent EE03 packing

I've been running EE03 since it was leaked.
The reason I stuck with it was because I saw EXCELLENT battery life (compared to SRF1.0.2. which I was running previusly) with the same usage (for me)..
Gingerbread was laggy at times, had some minute bugs that were tolerable (during my usage patterns) but I fell in love with the battery life.
On SRF 1.0.2 I would put my phone in airplane mode overnight to keep the battery from dying while i slept.. while it was a workaround (for me) it wasn't the most desirable solution.. I felt adventurous one night while on GB and left the phone sitting, no airplane mode, just to see how far the battery would drop compared to SRF... i only lost 5% overnight.. THAT was the ticket for me.. so i kept it and ran it.. haven't flashed a thing since.. no new apps, no new configurations.. it was working beautifully (as well as a leaked build could be expected to ) .. but it was very tolerable for me..
Until the last couple days... I noticed (all of a sudden) that while I'm sitting next to my computer, phone plugged in to charge before bed, the phone would disconnect/reconnect to the computer.. it would make that sound when you plug it in.. it would do this no matter what percent of charge it had.. for no rhyme or reason... I wiggled the cord in both the phone and computer in case the cord was to blame.. nothing.. i couldn't 'force replicate' this anomaly.. Further, at night around 4 in the morning the phone would vibrate and pop up that it was going to die, please plug in charger... the second night, I put the phone in airplane mode overnight and I STILL got the pop up at 3am that it was going to die...
So I decided (at 11:30) last night to ODIN back to EC05, then root w/ CWM 3.0.2.5. and flash SRF 1.1.1 .... I'll see how it goes.. hopefully battery life on this build is better than what I experienced on 1.0.2 lol...
Sorry for the long post.. I just wanted to share my frustration and see if anyone else had this weird anomaly w/ EE03.
/venting and pissing off the rest of XDA for long post

ive had the same problems with the disconnect/reconnect sound off. on top of what you have mentioned i have also had the problem of the phone being fully charged but showing the red charge light instead of the blue fully charged light. additionally the phone seems to get much more hot on this rom, i can simply be playing a game or something and the phone will get so hot that the charging is forced to be stopped, never had this problem untill the ee03,

I had the same issues , I was worried my phones charging port might be damaged but a quick flash back to srf proved it was the EE03 rom
Besides that, everything ran perfectly for me.

I've had problems with the phone not charging all the way. It will show 100% charge and then stop charging. When you unplug, it then shows the actual battery level, which has been as low as 35%. I've tried lots of things like wiping battery stats, but it keeps happening randomly.
EE03 is still fairly buggy. Some days my battery life is fantastic. Other days, it drains like a sieve. Even when I have fairly similar issues. Seems to correspond to how "hot" the phone is running that day. Also, phone calls just eat battery life.

going back to EC05 too... gonna be a long few weeks (hopefully only that). Awesome, just too hot, buggy, and I get PISSPOOR battery life.... but I have horrible reception at home, and even using roam control it still sucks down the juice. Also, I cant remember, is the settings process supposed to be permanenty running??? mine is, maybe that explains the settings not sticking... go samsprint go!

Its going to be hard for me to leave EC05. Full bars on my 4G. Wifi Tether is insanely fast and reliable. Bluetooth pairs properly. This has been the best modem for me by a mile

Yeah, the most I was able to get out of EE03 was 8 hours of idle time with the battery calibrated.

initially, I was getting stellar battery life, but the last couple days of using it, I noticed my phone getting hot. I have no idea why things were slick as snot for a long time, then it all went to hell in a handbasket.. good thing is it's easy enough to change to something else LOL (thanks Epic Devs )

EE03 has been strange for me at times. I've noticed when it's charging and it makes the charging sound, the battery life will be terrible the next time I take it off. However, if I just reboot it, it usually stops making the sound at random times, and the battery life is giving me 12+ hours/day.

[Q] HTC HD2 Won't Turn On Or Charge!

My HD2 recently froze, so i decided to pull out the battery, and now it wont turn back on
This is after i upgraded to Android 2.3.5 Gingerbread
How can i fix this?

More info would be really helpful. when did it freeze, during boot, after boot..did it ever boot up correctly and get pass the setup? are you using clk or magldr? can you link to which gingerbread ROM you used? sorry for all the questions but without some more accurate info we would only be taking an educated guess.
So my guess would be that it might just be coininsidense it froze and really the battery is just dead. Magldr does not charge when the phone is turned off so try and get a spare battery if you can to test it out. You might have some luck going into T-mobile and asking them about it only because they might be able to grab a battery out the back to test it for you. If your not using magldr other issues could be a bad download or you flashed the wrong ROM.
I use magldr and i had this problem once, infact it took me several days to get it up and running again. If you do find out its this which hopefully its all it is you can get a spare off ebay rather cheap. I bought three spare batteries plus a wall charger for them for around $10 or so...maybe $15.

Sounds like bent battery pins, which can happen when doing battery pulls.
Take out your battery again and look at the 3 pins that stick out and make sure none are bent and all connect to the battery.

Try this... Pull the battery, plug the phone into the charger, then while plugged in, insert the batter back into the phone.

The same thing just happened to my HD2. It froze so I pulled the battery out and now it wont turn on. The only difference with mine is that I was running stock software. I had not done any tinkering with it at all such as flashing ROMs to it and whatnot. Is it completely dead or could it just be a battery issue?

Battery might be fubar, I'd try another one.

To me it sounds like the battery pins if it wasn't for he said it froze, there is no description of when it froze but that it happened after he flashed a new ROM. If it was working fine for several hours and he hadn't pulled the battery out in that time then I would think its something else since it was working at one point. With out a little more info though we are just taking an educated guess...one of many things that could have happened.

Man, your suggest has just solved my problem! many thanks :angel:

pull out the battery. press the 'on'button for several seconds. press the reset button. plug the phone into charger. insert battery.
that worked for me

A battery issue that's driving me insane.

Ok, my battery(atleast I believe it's my battery) is having a serious issue, so hopefully someone will be able to help me out on this one. After flashing multiple roms and such over time now, this has never happened till now, basically whats going on is my phone will be completely charged, then ill unplug it and mess around with it for a short time then say the battery percentage is at 75% well randomly the phone will just completely shut off. When turning it back on the battery will be completely dead, or on occasion it will either be slightly the same percentage or lower, but most of the time completely dead. Ive been running the same old stock evo battery since the day the evo came out and im currently running Gruesomwolf's shooter e3d rom which ironically this all started happening the first time I flashed it. So hopefully someone can help out with this, been thinking the battery is just done for, but im not sure. So I figured i'd ask for some help and opinions on what to do haha

Sounds like the battery is done to me.

Your battery is toast.

since no one's said it, I think your battery is pining for the fjords.
Might want to clear battery stats and charge to full once while the phone is turned off, but I really think daisies are being pushed up...

Check and clean the contacts on both the battery and on the phone itself, being careful not to short the battery while cleaning it. Then, reinstall the battery and make sure theres not too much or any play where contact may be lost. If you do that and still have a problem, its definitely new battery time.

your battery might be dead but you should either try 1 of 3 things first:
1 - you can calibrate your battery
2 - Flash a new Kernel
3 - Flash a new Rom
you may find aosp roms/kernels in the link in my sig, if you are interested. hope i helped ^_^

Sounds like its toast to me as well. But you can try calibrating like others have mentioned just for sh*ts and giggles. It may or may not help.

Unplugging your battery and dropping a ton of percentage...that's normal with most evos...lack of an SBC kernel

If u clean the contacts use a qtip and 91% rubbing alcohol. Let it sit for 30 mins so the alcohol can completely evaporate. Then charge til green light with phone off, boot into recovery wipe battery stats, and cache and dalvik while ur there, reboot to phone run it completely dead recharge to green while phone is still off. Use like normal afterwards if battery is still acting up time to euthanize it and get a replacement
Edit: by 91% alcohol I mean the bottle says 91% on it not like 91% alcohol mixed with 9% water its the purest alcohol u can buy at the store

If u are using AmonRa try wiping the battery from recovery but before u do let charge for atleast a couple hours maybe that well help if not yep you need a new batter what kernel where u using and on what rom

Massive battery drain and an eternity to charge

Hi,
This past week, my G2 has had massive problems with the battery draining when I have been doing basic things like web browsing etc.... I can literally watch the battery drop %'s every few minutes... the phone also gets extrmely hot up the top of the phone around near camera, it gets to about 50 degree... and to make things even more worringly it takes all day to charge to full, instead of it charging to full in an hour or so it will barely get to 50% overnight..
Does anyone have any ideas what the hell is going on??? It's running stock EU KK ROM

I'm having the same issue. For me it seems to be triggered when I connect to bluetooth in my car. Once the battery drain is triggered it continues even after I get of the car. I've gotten in the habit of rebooting my phone every time a turn off the car. A major pain but it works until I find a better solution. I've been thinking about wipping the phone but I don't want to go through the hassle if I can avoid it.

First thing I guess would be to try a battery stats app (Gsam for instance) and have that running from a full charge to see if anything is running without your knowledge.

Not even with a separate app, did you guys take a look at the "stock" battery stats?
I had once a big battery drain that was caused by the media server.
If I helped you, please thank me

Ive currently tried every battery stats app i can get my hands on lol..... I've gone through the 50+ battery guide using titanium back up.... I've disabled startup programs.... Geez even Sonic the hedgehog Ep2 was for some reason just always doing something and i never touch it lol.... Anyway I'll keep a close eye on it but i still can't explain the long charge times.... Maybe something will come up
Yeh I checked stock battery stats, the main hog seems to be bluetooth when it's not even switched on :/

I actually *think* I found the very unlikely culprit.... Google Chrome Camera!!!!!! Someone else commented on the exact same problems as me on the Play Store... which sounds about right because I've had the charging probs about as long as I installed the app.... So I've removed it and hopefully thats fixed it

I could see the app maybe causing the drain but I think it highly unlikely it affecting charging. I still like the cable idea for your slow charge. Go find your white one the phone came with and try it =)
