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 got my G2 like amonth ago, lost the USB cable that came with phone the first day. Bought long cable off ebay and I am using it with wall charger that came with the phone. The problem is yesterday when I got up (I usually leave my phone charging overnight) it was at 75%. This morning when I got up it was 27% and it was charging all night. Checked battery usage graph and it shows like phone was not charging at all tho there is a sing in notification bar that it is charging. Tried few other chargers from S3 and S4. Doesn't matter what charger I plug in it estimates that battery will be charged to full in 30 HOURS. Can anyone help me how to fix this ?
Thanks
So as the title indicates, for whatever reason the nexus 4 is discharging after reaching 100% on the wireless charger. Now, this would be fine if it continued charging after it drains to a certain battery percent, but sadly that is not the case. When I take my Nexus 4 off of my wireless charger in the morning, I see that it has been 'on battery' for 7+ hours, and the battery is usually between 70-80% which isn't enough for me.
If it helps, here is some information that may be useful:
-My nexus 4 is rooted on 4.2.1
-My wireless charger is called "MoKo Qi Wireless Charger 3-Coil Charging Pad"
-I've tried restarting my phone, but the issue persists
-The wireless charger works at full speed with no issue (apart from the charger turning off when the phone is at 100%, and only removing and putting the phone back on it will turn it on)
Now, I've seen some threads where people say their phone isn't at 100% when they take their phone off, but they mentioned that their phone starts charging when it discharges to a certain percent (say, 95% or something) but sadly mine does not.
Any help is appreciated, thanks in Advance!

Edit: If it helps with anything, the charger makes a faint 'ticking' sound every half a second ONLY when the phone has reached 100% and continues ticking until I remove the phone. The ticking sound persists even while the phone is draining overnight on the charger. I have also tried to test if letting the phone reach 100% then draining the battery while it is on the charger by leaving the screen on changes anything, but it seems it doesn't matter whether the phone is 'awake' or not.
Bump
I don't understand the problem. Are you reporting fast discharging of your phone after 100% has been reached? Or you are reporting that it doesn't start to charge again when the phone drops from 100% to 95% or whatever?
In the second case I suppose that your Charger works in this way, and nothing can be done.

It would be the latter, the phone doesn't start to charge again when the phone drops from 100% to like 80-90% overnight. And something CAN (and HAS) been done, I hooked it up to a $10 Woods Model 50001 Indoor 24 hour mechanical timer, and made it turn on/off every 30 minutes during the night/morning. It works perfectly now, my phone is always at 99-100% when I wake up since it doesn't idle for 7+ hours, maximum it ever idles is 30min.
I was just wondering if it was an issue with all chargers, or is it just an issue with my phone... I'll test it with my brother's nexus 5 some time and see if it still happens (without the mechanical timer).
Hi everyone!
My Nexus had a great battery Life at the beginning..after 6 months,it started to last less,so i bought a smartwatch to help the battery last longer; but the things didn't get better. The phone overheat when using maps or play some games just for 10 minutes;when i unplug the charger at 11.30 am in the morning,it goes to a 50 or 40% around 4 o' clock pm in the afternoon just after sending some WhatsApp messages, and after have played 15 minutes..the battery drains really really fast..but worst of all,when the battery reach the 25%,suddendly the phone turns off,telling that the battery have reached 1% and is empty. If i turn on the phone again,the battery percentage indicator is still set to 1%..what's the problem with it?i have a faulty battery?Need to call the Google assistance?
The phone is stock,not rooted or anithing else.
Thanks a lot!
I have had the same issue.
Occurs sometimes when I'm on 10%, I power it back on and it says 1%.
The problem is if you charge using QuickCharger all the time, especially overnight, it can degrade your battery but in a way that it doesn't fully charge.
Try using a normal USBC cable you got and PC to charge it for a few days...don't leave it charging more than 3 hours.
See if it'll get better after a week.
I Always use the supplied charger from Google..sometimes a car adapter with a usb c- usb c- cable...how is it possible that the stock Wall adapter mess up the battery??
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.
