(Q) External battery charging issue - Epic 4G Q&A, Help & Troubleshooting

Does anyone else have this issue?
I recently bought the extra battery and charger (that comes with the second batttery) and here within the last few days, I have been charging the unused battery overnight and then it turns greens sometime during the night and then in the morning when I go to put it into my phone, it boots up but states battery life at always less that 60 instead of the full 100%.
So if anyone knows as to why this may be happening, I would greatly appreciate any feedback on this issue that has me pissed.
Thanks in advance and also if somthing like this has been posted then I apologize. I searched and did not see anything along this matter.

The external charger may be shutting off too soon. Do what Lord said.
Also please put a subject in when you start a thread like "External charged battery only shows 60%"

Its the same charger I plug into the the spare battery case thing to charge and the light stays red for a long time then it turns green as if its done charging but when inserted battery into phone and power up, its usually around 60% charged or less. But I pull charger out of the spare battery holder and plug directly into my phone and it charges to full ballery.

The battery holder like the phone has a sensor that tells it when to stop. It is working incorrectly....broken.

Charging light

My charge lights have been flashing back and forth from green to orange when I am in the car. What does that mean? Cheap car charger?

Sounds like it. I would try a different one and see if it makes a difference. I bought the cheapest one I could find and I've never had that problem.

sounds to me like a bad connection somewhere
From my past experiences the orange and green flashing light means the device has reached a critical temperature and charging ability has been suspended momentarily until the device reaches a suitable temperature.

Agreed. However, I think we should email HTC on this matter... I would like to know every possible factor of why the light turns green. why it turns red. Also, I would like a change as well.. I would like it if the light didn't stay green while the phone is plugged in and I just get a message. I would like it to blink in some way like 3 fast flashes. or something like that.
Could be temp. I live in AZ. It was 102 today. I think I was charging and surfing a bit. I have never seen my OEM charger do that tho. I will swap back and see

oh after you just said that... IT IS the temp. lol. IN OTHER WORDS. keep the phone cool. can't leave it on a dash or in a car. it will overheat. It has NOTHING to do with the charger.
Keeping anything cool in Arizona, in July, is not easy! I can't walk outside with the phone for five minutes without it getting up to 100+ degrees. If its in the sun for even a minute... Forget it.
It has been over 100 for something like forty days in a row.

[Q] Epic only turns on when plugged in?

My phone is only turning on when it is plugged in. The battery level is close to full.
When I take out the battery and put it back in without being plugged in, the battery meter shows empty. When I plug it it, it shows green and charge LED is on and it turns on fine when I press the power button.
I just am running EL30 from ODIN. No root.
Sounds like a bad battery.

Did you leave it out in the rain? My gf did that with her Prevail and now it always thinks it's charging on and off and when the phone is off it will only turn on plugged into the charger. We replaced the battery so that wasn't the issue.

The Best Buy Black Tie sent me a replacement crap 1200 mah battery. It charged to full and as soon as I unplugged it the phone shut off. That is why I thought of the battery.

When the phone turns on does it automatically shut off after a few seconds? When I had the GG battery it did that thy replaced it for free but they suck compared to hyperion.

It's not the battery. I switched batteries with another epic and had the same problem. The other epic was fine with my batter.

THe phone is perfectly normal other than needing to be plugged in to turn on. I did notice that when I unplug the charger/usb it takes a while for the LED to turn off and also it always thinks the is something plugged because the notification bar always has "USB connected".
Also check your battery terminals in the phone. All 3 should be the same and perfectly aligned and able to contact the battery.

UPDATE: There was no fix for this. Had to take it to sprint for a replacement. I think there was something wrong with the usb port where it would think that there was plugged in all the time.
Sounds right
Yeah that definitely sounds like the USB port is fubar'd. Sorry mate

How do I wipe battery stats?

It seems like it takes forever to charge my phone now how can I wipe battery stats?
Sent from my SGH-T989 using XDA
Has nothing to do with battery stats.
It gets auto wiped when you charge your phone to a certain level to almost full.
If it takes too long to charge, get a 1000mah charger and don't use a 500mah one.
Hope it charging from the wall and not a PC

Data/system/ batterystats.bin just delete it.. Or boot into recovery and clear battery stats...you can check your cable or change the outlet at which you charge your phone, you might also want to check your battery for leaks which could potentially damage your phone..

Can someone explain something to me.

So when I have my stock 1800mah battery in the phone my charger shows up as USB in the battery stats. It also seems a little touchy when it wants to charge. There shouldn't be anything wrong with the port since I just got the phone Saturday brand new from best buy. The thing that is confusing me when I put my old 1500mah battery from my SGS1 the charger comes up as AC like it should and i have no problem with the charger not wanting to work. Can someone help me out there

You could have a faulty battery, in which some of the cells in the battery may be damaged. How are you attempting to charge your phone? through a usb port on a computer or through an outlet?
Through an outlet.

Yeah most likely its a faulty battery. Manufacture defect

I'll try a different charger Saturday when I get back from my trip and if it still doesn't show up as AC I'll take the battery back to best buy ty

I also have an external charger but an extended life battery acted the same way. It wouldn't charge in the phone. I fully charged it in the external charger then ran the battery in the phone until it shut off. I repeated this a couple more times and now the battery seems to be behaving. It might be worth a try but if it's the only battery you have, then maybe not.
Well I tried using my cousin's charger and it shows up as AC so I'm guessing it's just something with my charger not my battery

Proper battery maintenance

Hello, I am curious what the proper maintenance for the battery is? I have 2 spare batteries and an external charger. Should I leave one on the hook all the time or let it charge the battery take it off the charger when it is full? Thanks!

Let it charge until full because it will get damaged if over charged.

How long should a battery hold its charge while not in the phone? I charged one fully and after 2 days I put it in my phone and I had 8 percent left :/

1) Lithium Ion batteries can't be overcharged.
2) If your batteries are going from fully charged to dead after 2 days without even being used, either the battery is garbage, or the phone isn't reading it properly. What level was the original battery at, when you replaced it with the one you had previously charged? If you plug it into the charger while it's in the phone, what happens?
There's something wrong with that battery if that's true.
I charged my spares a week to two ago and they're still at over 90%.
Leaving it on the charger is not something I'd recommend. It can be "overcharged" if there's a malfunction in the charger (it's not that this type of battery can't physically be overcharged, just that there are precautions in place to prevent it from happening) - and why tempt fate ? The protection circuits in the charger are a form of protection, but you shouldn't rely on them - even ones from the "good" manufacturers can and have failed. Failure can lead to overheating which can lead to a fire.
