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.

So lately I've noticed that battery life is strange on my Vogue with android. When I let it charge overnight, I take it off the charger and it instantly falls to about 97%. At about 1 PM the battery hits around 30% so I plug it in.
Here's the weird part: it's only charged for a half hour and it's reached 80% according to the meter. After another half hour it will say 100%, and stops charging. If I take it off the charger, it will instantly drop to around 77%, and lower quickly. If it says it is not charging anymore, but I know it is not full, is it really not charging? Can I just leave it on and expect it to continue charging to the real capacity?
Is this just how it is? or is there anything to be done about this? I've tried completely discharging the battery a few times, but didn't really help at all that I could tell.
Curious about everyone else's experiences
Thanks!
I think I remember reading somewhere that Android reads the temp of the batt. to figure out what % is left....
Try this.... When your batt. is low, take it out and blow on the connectors for a few minutes... See if your % rises.

Trying this now... lol
Would I have to do this every time I want to get a full charge? seems strange. Maybe this woudl explain why it charges overnight - longer period of time the battery can cool down, charge up more, cool down, charge
how long should the vogue legitimately take to charge? Seems as tho mine does well within an hour...

3 hours usually.

Perhaps my battery has just lost it's capacity - it is around 2 years old
Here's what I posted about battery issues in the thread for my Kaiser build:
Battery issues are due to the driver. It was written months ago and AFAIK hasn't been looked at since... I know it has some bugs, here are the ones I am used to:
Intermittent charging
stopping at certain percentages (like ~70%) and refusing to charge
when refusing to charge also does not detect when plugged into USB/ADB
won't fully charge
reports different battery percentage than WM
sometimes jumps instantly from ~30% to ~4%
reports connected to computer when only connected to wall charger
repeated USB-connected notifications
battery becomes hotter during charging than on WM
I should add also that sometimes when the battery dies in Android it won't charge in WM until I boot the phone in WM and unplug and replug the charger.
If I want a proper charge, I just boot WM and wait ~2 hours. Much simpler than Android.

well it could be that the age, my phone of 2 years got replaced after the power button snapped off, got another which i lost which got replaced by my most recent.

Gah, that's too bad.
When I charge overnight, I don't have problems. It's in the middle of the day when it isn't on the charger for too long that I have issues.
Thanks for confirming the weirdness though, at least I won't bother with a new battery (yet)
Plugged into the supplied wall charger, my phone will give the message that it's fully charged. I unplug it and it immediately goes to 98% and then if I plug it back in it goes back to 100%.
Has anyone else seen this? Is it a bad battery?
After it says full turn off your phone and let it charge for an additional hour, then turn it back on.
I would not encourage charging your phone while it is in.
I have not noticed this, but on my g1 it would take a bigger hit, but that phone got like 3 hours battery life, so it may have been accurate.
Does anyone know if it stops charging the battery when it gives that message that it's fully charged? If I unplug it and plug it back in it will top off the battery and I get 100%.
This occurs when the OS is not calibrated to the battery.

The OS is reading what is called a surface charge,
After you take the charger off the surface charges last from a few seconds on up to 2 mins. to get a full charge you have to let it sit for another hour or so with the phone off.
After my phone had been on the charger all night I pulled it off the charger and noticed my battery immediately went to 98% after I unplugged it. What seemed to correct this for me was I had to turn the phone off let it fully charge then for safe measures I unplugged it and plugged it back in again till it said 100% again. After doing this my phone now fully charges and stays at 100% after I pull it off the charger.
Just thought I'd share...

The reason for this is for battery health. The phone will actually slowly leech a charge down while plugged in once it hits 100% and then recharge. The reason for this is because it's bad to leave a phone at 100% all the time. It's normal for that to happen with phones. Some phones are more accurate with displaying the proper percentage than others.
Thats odd. My phone charged to 100% yesterday and after about 30-40 minutes of rarely any usage it was still at 100
yeah it happens from time to time. But its easy to remedy.
Today my phone ran down to 0% and it shut down. When I got home I plugged the charger in at around 5pm. Now almost 7 hours later it is still not fully charged. This has never happened before.
Do you know what could be causing it to take so long?
It is plugged in to the wall.
Thanks.
either the phone is not charging at full rate or is discharging very fast. I would try to charge with phone being off, monitor battery discharge during day especially in IDLE and take it from there. You can also download program that shows charging rate.
So, I'm using the OEM charger that came with the phone. For the past 2 months the phone wasn't charging properly. It says it's rapidly charging, but the estimated time left was showing anything between 3 and 6 hours. In reality the phone charged to a 100% in about 3 hours. At first I thought my power outlet was the problem because it didn't behave this way every time. For that past 2 weeks it always charges slowly and sometimes even drains my battery. Last night I plugged it in and the phone had 40% battery, when I woke up the notification light was blinking red and the phone was off.
I think my charger is the culprit because the battery life is fine. Should I buy a new charger and if yes, what charger do I get because I can't find an original one anywhere ?
Thanks in advance.
