I'm having this problem while charging my battery during the night. I'll plug the phone in when i'm in bed, and when i wake up, the phone says charging but it will be down to about 85%. i've had it show up at different levels multiple times (78%, 80%,88%, 92%, etc.) i know that the battery will charge completely and then stop charging for a little bit as to not damage the battery, but going all the way down to 78%????
any thoughts?

So my battery is at 56%, I hook it upto the charger it's been on the charger for a good 2 hours now. I unhook it and my battery suddenly is at 30%...
Also I've noticed that my device gets hot, not burn your hands hot but noticably warm hot.
Should I be worried? Could there be a short somewhere, the device is just 3 days old.
was your wfi turned on during charging?
Yes it was
that sounds really bad especially since it didn't charge
did the light come on? you might want to consider getting an exchange
Yes the light did come on and the charging symbol did apear on the screen.
If wifi is turned on and set to best performance, and if you have backlight set to remain on when connected to external power, your device will drain more power that charge.
that will explain your battery/charge/heat issue
Actually I can confirm this shouldn't be true. I turned WiFi on, turned my brightness to maximum and always on. In about 10 minutes I went from 52% to 54%.
I was using the wall adapter to charge it. USB charging might be too slow to replenish that kind of drain.
definately exchange
you don't want it to blow up
After have Touch HD for 100 daysI, have got a problem with it, it is about battery charging.
When HD turns on, it shows battery is low, then HD turns off automaticlly.
I tried charging battery with AC or USB, the Charging light is on but after hours, when turn on the devices it still shows battery is low, then turns off.
I changed a battery, it goes well, the device is on with all the fuction running well. and the previous battery is working after change the battery again. and it shows the battery is 90%.
But after a day. the problem is back again. and this time no matter what battery I changed, it still shows battery is low. and won't charge. even with the full battery the problem is same.
If you have the experience with this, please I do need your help.
BTW, The rom is from the factory.
Maybe the battery is fine, people have experinced problem with the actual charger. Have you tried charging through the computer?
Yes, I have tried charging with Computer, AC adpator and even Only charges the battery.
But the problem is not solved.
I suspect the HD's battery chip which manages the battery charging maybe broken ( if there is a battery chip)
Disconnect the HD from USB/Wall outlet. Remove the battery. Short circuit the pins in the HD battery compartment with a wire/metal piece. (never short the battery - it may explode!).
This helps in most cases for this problem. If not then warranty is the way to go.
I've been experiencing problems(like most) with battery life on the Epic, so I found a thread here from the EVO forums about "recalibrating" the battery. It involves steps of fully charging with it on, removing cable, powering down, plugging back in, etc...
Well I've actually come to realize that a blue LED should turn on when the battery is fully charged & the phone should stop charging(duh). Well i've tried for the last two days for the blue LED to come on after countless hours of charging, resetting the phone, etc. I've now had my phone on the charger for 8+ hours & my battery widget states 100% yet it continues to charge!
Has anyone else experienced anything like this?
No, but my wife's battery would drop immediately from 100% to 75% as soon as it was removed from the charger. This occurred no matter what charging regime I tried. I know that the battery may start to discharge after its peak charge has been obtained, and that it is possible to remove the charger and see only 90% on the battery, but 75%?
I returned that battery last night and now today I see that this battery never gets past 98%. I'll give it a day or so to see if the battery life degrades again, in which case I'll know it is the phone and not the battery.

Are you getting the blue light and what app are you using to tell what percent? There are other thread that say some of the battery apps are off a bit. What kind of battery life are you getting?
Success!
I used a few different apps to tell the battery charge so it wasn't the apps.
I found a fix that not only allows my battery to charge to 100% but also seems to give a better charge. Since doing this my battery shows 100% when fully charged, doesn't drop significantly when I unplug the phone, and so far has caused the battery to go down very slowly. In the three and a half hours since coming off charge the battery has gone down to 93%, while holding up to my wife using it for calls and ShopSavvy. I intend on doing the instructions below every few months.
In the Evo space there are two sets of directions on how to prep your batteries for a good charge. One involves plugging and unplugging your phone while at full charge, and the other involves briefly turning your phone on and off between charges. Because I'm impatient I've amalgamated the two with success.
Fully charge the battery with the phone on (several hours)
Once the charging light is blue, unplug the charger
Turn the phone off, then plug the charger back in, for 30-60 minutes
Unplug the charger, turn the phone on for two minutes, then turn it off.
Plug the charger back in for 30-60 minutes
Then repeat this cycle about ten times: unplug the phone for five seconds, then plug it back in until it says it is at 100% (about two minutes)
For the record, I think this has little to do with the battery and a lot to do with how the phone recognizes the battery as full.
I haven't had any of these problems. My battery charges %100 with blue light and it doesn't drop after I unplug it either. Guess I'm lucky

I don't run a battery app. When the blue light comes on it's done. I get about 11-12hours before I get the low battery warning.
Ha! It really worked. She's at 17% and its been 1 day and 11 hours. Not as good as my Evo.
I guess I'll re-try calibrating the battery again, first time I tried it my battery ended up at 95% instead of the regular 98%, really odd.

That seems a little crazy. All you should really need to do is drain it until it won't power on anymore (not even for a second) then charge to 100%.
Still, the epic's sensor just isn't very accurate at the top-end (most aren't), so you're gonna get some strange behavior near the 100%.
All the older WM phones were weird like that too in the 90% range; the sensor just can't detect it very accurately near full charge. The difference was that they showed battery in 10% increments, instead of 1% (unless you use a hacked driver).
too crazy for me.
I think I'm going to just buy some spare batteries for this phone. Immediate unplugging leads to 100% battery.

I have the same problem, I'm using battery life and juiceplotter and they give me the same %

Thanks for this. I was having trouble getting my device to recognize the top 3% of the battery, and one iteration of your plan above did the trick.
^After I noticed these steps in the Evo thread last week, following them did the trick for 1 iteration.
My phone rarely has stayed long @ 100% after coming off a full charge since then, though.
I left my phone charging overnight via the wall charger. Battery registered at 1% when I started the charge.
When I woke up this morning I had a large low battery icon on the screen and the phone won't turn on. I disconnected the charge, tried charging with another charger but everytime it shows the SAMSUNG logo, then the large low battery icon.
I tried removing the battery, cleaning the charger port terminals, swapped out different USB cords, everything but a hard reset.
No matter what I do the phone will not start up.
Has anyone experienced this before, or possibly no how to resolve it?

Happened to me several times (on both my focuses Rogers and AT&T), and I came to the conclusion it's a bug somewhere in the phone or the battery. I'm not sure exactly where the problem is (software, hardware) but I can tell you how I fixed it.
What happens is, the battery is almost depleted, it actually is 1%. The phone incorrectly reads that thinks it's charged fully and doesn't allow further charging the battery. So, you're not able to charge the battery correctly.
Now, as I previously stated in some other posts, I recommend having a standalone charger (Samsung i9000 ones are compatible are very cheap) as well as a secondary battery. The depleted battery gets charged fine in the standalone charger and when it passes 5% charge, it can be charged fine (again) in the phone.
This doesn't happen often, I believe it happened 5 times in more than 300 charging cycles (2 phones x 150 charges, I have them for over a year) so it's not that common.
I also found that it *may* work if you charge the battery in another phone.
As a general thumb rule, it's important not to leave the battery to completely discharge, and connect the charger/usb when it reaches about 40% (when you can, ofc). Please refer to my post here to see how you can preserve battery life.
So I noticed last time that while the phone was plugged in to charge, the battery started to drain instead of charge, even though I wasn't using it, which was kind of odd since it drained pretty quickly. Unplugging and plugging back in seemed to fix the problem, but when i tried to charge the phone today, somehow the battery instantly jumped up to 100% and it doesn't show up as charging.
Is this a software bug, or is there something wrong with my battery?
I've been having similar issues. i would leave my phone plugged in all night and it would be charged to 80% when i wake up in the morning.
Yeah, sometimes mine charges really slowly too, but in the screenshot the battery doesn't even charge and drains faster than when it is idle.
