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?
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.
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 was reading that that a lot of you guys have issues with Android not displaying the real charge of the tablet and I was experiencing this issue for a while as well. In my case it was an easy fix, simply power off the tablet, carefully pry off the back, then disconnect the battery cable carefully (it's the cable coming from the big black thing on the bottom, google to find out where), finally hold the power button for about 10-15 seconds with the battery unplugged, this creates a static reset, using all of the electricity in the device and discharging it fully; it fixes all sorts of ****. Put it back together and you should be good to go.
It happened yesterday to my totally new nexus 7 16gb.
I charged it for about 8 hours while the tablet was turned OFF. When I turned it on it appeared to have 60% of battery... :-/
I reset the device and then again 60%..... So I charged it again and with no problem appearing, it charched untill 100%..
That happend only once, in its 3rd charge.
Any idea?
battery stuck at 0%
I was having this problem as well, my nexus was showing 0% battery. I took the back cover off and figured out that the battery cable was not pushed all the way into the socket. If anyone else is having this problem be sure to double check the battery cable is all the way in.

i experienced that too.switched off then after 5 hours of charging, the % was 54%. then i unplug the charger, remove the cable, unplug the 3pin . reinsert all the 3pin and cable, then continue charging. surprisingly, the charging the is quiet fast. so dont ever remove the cable from the charger. maybe there is something wrong with the asus charger
I am facing weird battery status..it shows me 0% in red danger zone even though fully charged, but after some hours status changes to normal remaining battery...I unable to understand how can I fix this...as I am not getting exact battery status...its now also showing 0 % with charger plugged....

worked great thanks
I found the black wires askew pushing them back in did the trick thanks!!
Nexus 7 2012 1st gen 0% battery but on battery settings says 2 days

I did this took battery cable out and reconnected but still showing 0% battery but it shows 2 days battery on battery settings and still wont let me update from 4.4.4 to L5.0.2
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.
