Samsung Epic battery won't charge!!

When I got my Epic the battery was at 50% like expected. I immediately plugged it in when I got home and it seemed like it was charging because the charging light was on and the battery indicator was showing charge.
About 1 hour later I had to leave for class and I unplugged my epic. It stated it was 15% battery left and gave me the sad low battery notification.
I plugged my epic into the wall at school and let it charge a good 2 hours. Throughout the charge the battery would NOT GO ABOVE 15%. I finally unplugged it a few minutes ago, and STILL the battery is at 15%.
Is there any way to reset the battery stats or is this a faulty unit?? I called my radioshack nd they stated they can do a phone swap for me BUT THEY DON'T KNOW WHEN THEY WILL GET MORE EPICS IN. WTF. I obviously can't use a phone that won't charge..... I saw a similar problem on androidcentral forums, where someones epic wouldn't charge over 80%.
My radioshack lady said to take out the battery and reset the phone. I've done this 3 or 4 times and still the battery registers 15%.

I'm having the exact same problem except my phone always thinks the battery is at 0%. Even when plugged in to charge, the phone will still occasionally die. It's very likely that I'm just making some silly mistake though, as the Epic is my first Android phone.

I had on USB debugging but I don't think that should affect charging through usb. I don know what's wrong with the charging port or the battery. But its definately going DOWN. Now its blinking at 0% with no way to charge it.
I'm wondering if I let the battery die and try to charge it to see if it will fix the battery.....

Same issues until i plugged it into a wallcharger.. now im good

meaning a non usb charger

I have tried the usb wall charger that came with the phone, and also a generic microusb charger. Both light up the notification charging light, and then the battery shows the charging..... still won't go above 15%.
Argh!

easy fix guys....
be sure to use the original charger and usb cable.
plug in the charger to the wall, then plug the usb into the charger, then plug the phone into the usb....
follow these steps exactly and it should start charging......
(in the future, dont let your phone completely die)
PS: this issue affects ALL epics when they die completely so dont bother taking your phone into sprint. they will not replace it because the replacement would do the same. (2.2 should fix this..... its only a couple weeks away)
hope that helps!! ENJOY YOUR EPIC!!!

I have tried this, charger into wall, then cable into charger, then usb into phone.
Still phone will not charge.
If I unplugg the charger, it says the battery is empty.

aww man that sucks, maybe the battery is defective? u should try going to the sprint corporate store that does repairs. they should be able to test the battery and if its defective give u a new one.Its still under warranty, and if u have TEP it definitely is covered.

My Epic was experiencing the same issue. When I first got it today, it was gradually charging fine via my new Thinkpad's USB port. But then for some reason, "Battery Indicator" showed the charge going down, even though the red LED and the battery icon indicated that the phone was being charged. So did my lock-pattern screen. I called my local store for a replacement.
The phone wouldn't charge while I had the rubberized phone cover on, bought from the Sprint store. Also, the phone felt very warm, so I took the cover off, opened the battery cover to see how hot the battery was. It didn't feel too hot to the touch. I removed the battery, put it back in, powered the phone back on, and saw a huge green battery charge icon, but alternating with an icon with what I think was a yellow warning sign, and a thermometer on it. So I left the Sprint rubberized phone cover off, and recycled the power on the phone.
After the phone fully loaded up, I tried USB-charging the phone. Now, it's gradually charging up (was down to 14%, now back up to 19%). The phone feels cooler, too.
I'm leaving the replacement option on the table in case my phone turns for the worst. I rely on the phone for work and business so can't be without a phone. Maybe I should reconsider getting a land-line or VOIP service again. But maybe, this being a brand-new phone, the battery needs to be cycled a few times before it stops acting unusually. I'll try the wall charger before I head to bed tonight, and see what happens tomorrow.

Here is my findings after putzing with it all day. I was using two chargers. Both griffin's. One was cigarette plug to usb with an output capacity of 1 amp. I also have a wall one that has a usb port and is meant for an ipad. They need lots of current to charge them and this one is capable of 3 amps.
Using the evo, both could charge it and run the phone at the same time. The battery percentage would always increase. With both of these chargers on the epic, even though the charge light would be red, if I was using the phone, it was not charging and it was pulling off the battery to run the phone.
This should not act like this. I have read that these screens are supposed to be more power efficient, but I don't notice that. I do not know if the power regulator in the phone is wimpy or not but I noticed that when I played something loud through the speaker, the screen backlighting would dim when the sounds peaked. Come on! An amp and a half battery in this phone should be able to handle that.
Here are some more observations. About three hours before I was to go home, I would either put the phone on the griffin wall charger when I was inside or I would put it on the griffin 12v adapter when I was in the car. Finally around 45 minutes before quitting time, the charging led went blue. I was mostly charging the last hour with the phone off. I turned it on but kept it plugged in. By the time the home screen came up and everything settled down, the battery would be at 95%. I was like wtf. I left it on until it charged up and the light went blue. The battery was at 96% at full charge.
I kept hitting it with the charger. Unplug it for a few seconds then plug it back in. I repeated this many times. I would also charge until blue then turn off and let charge until blue. I would follow that cycle for awhile.
Lastly, I left it turned on and charging but would unplug it for a few seconds then plug back in. The maximum % would inch higher and higher. I got it up to 98%. Then I noticed that when the screen came on to tell me it was fully charged, it was at 100 for maybe a second or two then it would drop to 98. I suspect the screen was causing the drop. All the time I have been typing this, I have gone from 98 to 90 while on wifi, screen minimum brightness and using hardware keyboard.
This was my battery and charging findings for today. Add this to the theories out there flying around.

I find that completely unacceptable if the phone can't charge if being in use....
I plugged it in the way mentioned earlier for about 30 minutes while I was waiting on a friend. The charge went up to 15% but 15% isn't gonna last me longer than a hour of use which isn't usable.
It stil won't go above 15%.... I'm gonna leave it alone for a hour and see if it will charge, but a phone that can't charge isn't of use to me.
And judging from what everyone says its not even a hardware error, if there are many people with the problem.....

is this a defect, or is this only isolated to some phones?

Ive been testing finding battery charge of 2% every 10 min while connected to desktop charger Telanav enabled so somethings definitely wrong with your device.
I would take back asap swap for new

So I just got home and plugged my Epic in yet again. After about 30 minutes of charging my battery is at 20%.
Still way slow but the battery has gone above the 15% sliver of battery.....
I'm thinking its because the battery has to be conditioned... I'm gonna charge it for a day to see if the battery performance changes...
Sent from my SPH-D700 using XDA App

I'm gonna try turning off the phone while it's charging at night and see what happens. Or I could try the htc evo battery conditioning suggestion.
Full 8 hour charge on. Disconnect charger and turn off phone. Charge off for an hour. Turn on and wait a couple minutes then turn off and charge for a hour. I think maybe charging the crap out of it might condition the battery some.
Maybe kinda like filling your gas tank up until the lever pops. Then slowly keep filling until it pops again. Then push the rear of the car up and down and side to side to try and get the tank to burp out any air pockets. Then slowly top it off until it barely overflows the filler pipe. I know, stupid mental picture!
The only questionable thing I have is, after a "full charge" should I run the phone until it shuts off then give it another FULL charge? Some say yes, some say no. Each have their theories.

I noticed that the "Where" application was sucking down a tremendous amount of juice. There are multiple similar complaints for it in the Market. Uninstalled it, and now the phone is charging gradually and steadily.
@ 9:57PM, battery life = 36%. Now @ 10:25PM, battery life = 48%. I'm cautiously optimistic.
With Where installed, "Battery Indicator" displayed a voltage of <3V. After removing it, voltage is now a hair < 4V (3.945V is the latest refreshed value).
I will be following herb's suggestions for conditioning by maxing the battery out tonight. I think I'll run the phone down to 0% tomorrow, once it's fully charged to the hilt.
Even so, I still intend to exchanging this unit out because I'm also experiencing issues with the Back soft-button.
Considering encasing it in that Sprint rubberized casing tomorrow to see if it affects the battery life.

My Epic has no problems except for the battery being slow to charge, but i charged it to 80ish in about 2 hours.
If anything, I will try to switch it for a new battery.

I just thought of something that may be nothing. Did anyone, like myself, update google maps to 4.4.0? I am going to try something and see if it helps.
In battery use details, in the about phone under menu, what is your highest battery consumption? My display is pegged all the way and it is at 70%. The next closest is cell standy 14. Then browser is 9, system is 4, idle is 2 and os is 2. I'm going to remove the maps update. I read somewhere that some people suspected the update to eat battery.

I haven't updated the maps app. The screen and standby are the highest ive seen on power usage.
My radioshack wont have any more Epics in until Friday or later.... I'm gonna try to power cycle the battery (if I can leave it off for that long. )

Anyone tried wireless charging ?

Anyone tried wireless charging on DT2 or MXF ? And how was the experience ?

Works, nothing special - overnight charge from 1% to 100%

It works, but many of us have problems with the Qi charger disconnecting charge at 100% and then reconnecting after about 5% has drained. Motorola is looking into it. I may be picky on which Qi charger you use.

Maybe I did not notice this problem - as I put the phone on charge in the evening, until the next morning I take it to work.
I use cheap qi charger from ebay - ~$2.5

Use a ravpower qi charger every night, no issues, phone comes off 100% full, cool to the touch. I know some units I've tried with my Maxx back in the day kept it warm through charging.

Hm, I haven't had this issue yet. I use a cheap generic three coil Qi charger. Is the issue just Qi or PMA chargers too? Because I was looking at buying another but this issue would be a little annoying to me.

Exactly how it should work to prolong battery life. Keeping any battery (especially lithium) full charger for long period of time will significantly decrease its capacity.

My phone gets very warm wireless charging. I prefer fast charge

Never had a problem with that in the past even with wired chargers. I don't think in recent phones that there is actual current on the battery at all times past 100% whether charging wirelessly or wired. I'm pretty sure it goes into a maintenance mode, but it will still show charging on the display which is the important part. That is important if you use it on your nightstand as an alarm clock with wireless charging. My Sony Z3v had no problems staying in a charge state even after 100% but my Turbo 2 does not which causes it to disconnect. It will reconnect after it loses about 5%. If I don't have it silenced, it will wake me up when it reconnects. It also affects any tasks you have programmed to happen when it is charging.
From my understanding, the first Turbo did not have this problem. I think it cropped up from the inclusion of the powermat charging or maybe something related to the 810 processor. Anyway, just waiting for a definitive answer from Moto.

Read the thread at the Moto Support Forums. https://forums.motorola.com/posts/215aa2bb51
It doesn't seem to affect everyone which may mean it is more dependent on your charger.

Have any Qi charger brand to propose ?

I'm using a Samsung Qi puck - not the newer round plastic one, but the older more squared soft-touch one. Works great, I don't have the 100% disconnect issue.

I use the tylt qi charger the desk top one so my phone is sitting at a 60 degree angle. It works great no issues and every morning my phone is at 100% and cool to the touch

This all sounds encouraging. I think it would be helpful if people could also add a few common notes:
charger / model
any case they have on the phone (or not) when using a Qi charger
whether the phone must be in a certain orientation (e.g., horizontal vs vertical) to charge
whether the phone is at 100% - and stays there after a charge
whether the phone is cool / warm / hot once charged
A cleaned up list developed from this would be a good resource for the user community

Tylt works great phone gets warm. Itian charger is cheap from Amazon but is very finicky.

Uhm, that's one of the sillier things I've read today.
If it drains to 5% it's not terribly useful as a charge system regardless.
A charge controller chip is supposed to be designed to PREVENT the problem you just described.
Each charge cycle, regardless of it's form shortens the life of the battery, period. If you charge it up and then let it deplete it like that, you're damaging it as much as if you left it charging.
You kind of need to leave the stupid thing plugged in or in some wireless charge hysteresis loop so that the device isn't drained. In light of the charge system being supposed to keep the battery out of the loop until it needs to charge it again (some threshold below 100%) it shouldn't MATTER if it's "plugged in" and the device won't be pulling from the battery.

You're talking like battery expert. Well, maybe you're. Then contact those guys and tell them they're wrong
http://batteryuniversity.com/learn/article/lithium_based_batteries

I picked up 3 Samsung qi chargers at 6 quid each on offer on Amazon (UK). They work very well although they are more a convenience thing rather than a method of charging. I use one at work. One in the bedroom and one next to the Xbox great for the work desk to keep the device topped up and frees you up from plugging and unplugging constantly BUT.... It takes absolutely ages to charge so you dont go expecting to be dumping your cabled chargers. I use the work one most of the time as I'm out and about a lot and its very useful to be able to just grab the phone without unplugging and placing back on the pad when at the desk. The turbo charger gets used at home more coz in more likely to plug in to that and jump in the shower knowing that I'll have a nice reserve of power for the pub so yes they work as advertised and work well great as a trickle charge device when you ain't in a rush. If anyone is interested ping me and I'll spend some time on giving more detailed stats such as charge times from 0% and model number of the devices I use. Away for work at the mo so probably the weekend

Raynic
I bought the Raynic Orchard I. It charges the phone just fine, but I noticed that if the phone wants to wake up because it senses movement, it detaches and reattaches to the charter, which gets very annoying. I moved the phone to an angle where it couldn't see me (but I could see it; sensors were under my monitor stand but the rest of the phone was sticking out) and everything went smoothly after that.

Verizon QI charge stand, Verizon case, have to charge upside down
To charge our new Turbo Droid 2 in a Verizon QI stand with the Verizon case on it, the phone must be upside down. It's OK if out of the case. We have a car QI 'base' which it won't charge in either; probably exact same issue, whatever that is. Any ideas appreciated!

Charger gets incredible hot. Almost burning my skin.

Hi
Recently (no matter what charger I use) it gets incredible hot. The phone is just "normal" when charging. The thing that gets hot is the end that you put into the phone. When it reaches 100% it stops charging and cools down., so it doesn't overcharge.
It do not get hot when I use my wireless charger either, so the problem is only there when I try to charge my phone directly. If I fast charge it goes fast, but get incredible hot and if I turn fast charging off i'm lucky if the phone is fully charged the next morning.
Any idea what this could be? For now wireless charging is my only option.. Fast charging is too hot and turning it off result in over 10 hours to fully charge.
I have tried changing rom, clear everything, changing kernel, stock, modified and so on..

I had the same issue as well. I've seen some people reported that they fried their charging port because of that. I called Samsung and they gave me a replacement charger. Haven't noticed any issues with the new charger yet. So, my advice is get a replacement charger.

Samsung replaces faulty chargers with no major obstacles from the buyer's side - if you have Samsung's warranty service nearby, they will replace the charger right away.

Nexus 5x usb port melted

Hi all.
This morning I woke up as usual and tried to unplug my phone from the charger with one hand. It didn't un plug.
I had to force unplug because charger plug melted inside the phone usb port.
A black smoke came out from the charger plug
The result is an unusable nine months old phone, a burned out night stand, and its original cable (with original charger) completely melted inside the phone.
It's a luck it happened in the morning.
I see someone else did already have the same issue.
LG shoud think about it. Maybe there is a defective stock of cables that should be checked and replaced.
Cheers,
David.
PS I cannot post images, its a long time i do not enter here and my account did not exist anymore
So now i'm a newbie again!!!!
Private message to me and i'll send you the images.

I just bought mine last November 2016 and I'm aware of this issue before i got my phone. Since i got mine, i didn't attempt to charge it overnight because of this issue. I just charge my phone while i'm preparing to get to work and by the time i'm ready to go out (which takes me 30 mins to prepare) as nexus 5x has quick charge capability which is really fast, from 15% to 85% in just 35-40 mins.
Although phones should be really handle the charging limit once the battery hits 100%, but i think the charger (which has a 3.0A) can't do this. Do you still have your warranty up? its better to send your phone to LG with the charger and they might issue you a new phone.

Actually, you shouldn't care about time charging. When phone is fully charged, the charger should turn off or not charge the phone.
It's more than ten years I charge devices in the night. Never ever happened a thing like this.
I'm curious what LG will answer to me......

I also charge my previous phone (Sony Xperia Z3 Compact) every night and plugged it out in the morning. But When i heard that Nexus 5x has this issue, i just charge my phone before i go in the office, since i'm fully utillizing its fast charging feature.
I already read some thread here and there are some particular model of chargers that doesn't pass some test.
My charger model is: DONGDO (MCS-N04ED)
My Phone Unit: LG-H791

It happened to my phone before, with the usb a to c cable from Google, I charged it from a notebook usb port, and soon after, I smelled some plastic burning. The device was unplugged, and the phone charge normally with another cable over usb or with a wall socket. I called Google and they are willing to exchange for a new cable

I charge mine every night for a year with stock charger and never had problems

XT1575 suddenly charges very slowly

Could my work on my XT1575 cause the phone to charge very slowly? As long as I was using a good QC3 charger and a QC3-certified micro USB cable my MXPE phone charged fast. I have TWO working XT1575s. When plugged into the same charger with the same USB cable they both showed "Turbocharging" and both charged quickly.
Last week I replaced the back of one of the phones. -- exchanging the original back with an ebony wooden back. I had problems getting the ebony back to stay completely adhered so I installed it, removed it, installed it again with better adhesive. looks fine now.
Now, the back is securely in place BUT THE PHONE WON'T CHARGE FAST ANYMORE. Could I have damaged something in the phone while doing all that heating during the back replacement? I use a heat gun, always on the low setting, but I for the last installation I moved the heat pretty slowly around the back to increase the heat and hopefully improve the adhesion.
Everything about the phone works perfectly, both hardware and software. When I plug in a charging cable is shows "Turbocharging" but the charge time estimated by the phone is 7 or 8 or even 9 hours. That's about how long it takes too. And the phone won't charge past about 90%.
I've already replaced the battery. I have no idea how to further diagnose the problem. Have I effectively destroyed my phone while putting on a prettier back (to summarize how stupid I'd feel)?

Either you have a cheap low quality battery or you probably burnt it up with the heat gun. The NFC pad is on top of the battery if that still works then I highly doubt anything else was damaged but I could be wrong. Worse case scenario you desoldered something on the motherboard but I doubt it. First check the wattage on your wall charger if it says 5 volts and 1 Amp then that's your issue. Most wall chargers or USB ports I use have to be at least 5 volts and 2 amps or it will not charge and it'll actually get stuck at 90% like in your case because the charge rate slows down after 80% I believe and a crap wall charger won't have enough power to charge the phone like a high quality OEM wall charger would.
