Ok so I just charged my battery all day, it was at 100%, took it off charge.
5 minutes later I plug it in to charge while im at my desk and took the battery out for about 5 minutes - phone was still plugged in.
Put the battery in and its flat. I get a warning saying its below 5% and now I need to charge it otherwise my phone shuts down
I know full well the battery isn't dead, but the phone thinks it is
Whats the deal?
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.
For me there is a very strange Battery charging on my HD2 with WP7. I'm normally charging and after a hour the green LED is shown. But When i unplug the cable und plug it in again, it is charging again ^^
Is it a System Bug? I don't know when my Battery is really full, cause it can't be, that after 30 minutes the battery is draining so much, that i can see a not full batteryicon. Ah and after i make a reset, so reboot my Phone, Battery is again Full.
Maybe it's like on Apple where it is sometimes under 15 % then again on 30% then on 45%, after some minutes again under 20% :-D
So I just back my tablet after it being away for 10-15 days for repairs. It hadn't been charged once in that duration. Now however the battery is zero and I've been charging it for an hour and it's still stuck at 0% and says "0 seconds on battery." And if you unplug the charger it says battery low and shuts down. Is this normal due to not being charged for a long time? Or it something to be worried about?
i have the same whenever i do not use the charger cable that came with it. i dont know why ...
Has anyone figured out this problem? My nexus is at 0 percent and when I turn it on it just turns off after 10 seconds. I left the cable in over night and it did not charge at all. Would appreciate any help.
I got an external Samsung OEM battery charger (EP-B600CEWC) with an OEM battery. The battery works almost perfectly, but has one issue.
When charging in the external charger, it actually charges quickly, EXCEPT it takes 11 hours for the charger light to turn Green. If I take the battery out of the charger after 2.5 hours or so, although the charge light is still red, it shows fully charged when placed in the phone.
When I charge the original battery that came with the phone, the charge light turns Green after about 2.5 hours.
Oddly, when charging the apparently defective charger battery in the phone itself, it charges quickly (1.9 Amps), and the LED on the phone changes from red to green in about the same time as the original phone battery. In other words, the battery behaves normally in the phone, but it does not behave normally in the charger.
Anyone understand what might cause the extreme delay with the external charger LED turning green?
