well when i first got my phone i only charged it when the battery light was red and hollow. And at times i would put it under my pillow due to the alarm being so loud, didnt want to wake up my son.
But the past few days when i charge it and put it under my pillow it gets really warm, it never did this before, any reason why?
AFAIK all phones do, as well as any battery you charge (MP3 players, laptops, etc).
yea I agree, I think that is something most smartphones do, my mytouch did it... so did the g1
Thats because it charges at 1000mA via AC.
Don't charge it under your pillow! definitely not good for it.
Today I charged for an hour my n1 over usb.
It was really hot.
Then I go to home, and when I arrived, it was again really hot, and battery life is over.
So I reboot and now is ok, but is very very strange...
yeah they get hot, i have the battery life widget and also shows the battery temperature, when it was charging it peaked to 110 degrees lol
I came from a mytouch 3g, didnt have it long, i love Android, i guess i change the alert to something more calm. But before i charged it under my pillow and it never got hot. Maybe its a wear and tear thing
Any device to which you're pumping power into, or using power, generates heat. That's how it works. The only difference between the devices is how much it draws; the more it draws, the hotter it gets.
Yep. Don't charge under your pillow. It needs air or it will get super hot. Not a good thing.
Man...I thought my N1 was going to burst into flames today. 114.5 degrees...not sure if it would have gone any higher.
I was in the car using an AC/DC adapter. Had my navigation going along with my music. The glass on the phone got hot to the touch! I unplugged it right away.
How high of a temp can this phone endure without damage? If it were to overheat, would it just freeze up and shutdown?
Anyway...what's really weird is that the phone was plugged in when battery life was at 80...when before I unplugged...it was at 79. Huh?
warm nexus!
i charged my nexus tru the usb a few days ago, yes it got warm like always but when it was fully charged. it stayed warm even when it was unplugged from the usb. i know that was kinda odd and it drained the battery, it was at 76% just after 30mins. so i reboot and everything went back to normal. what the hell?! i think its a bug. what i do now just to be safe is i reboot the nexus after every charge and check if it stays warm...
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. )
As the title says, Phone won't turn on. There are no led lights at all. It does get warm after being plugged in for a little. I had jrkruse's hybrid_bra1 stock safetynet samsungpay...... rom on it. It was rooted. Very minimal processes running. I actually had basically everything stopped and greenify on. Phone was around 40% battery. I plugged it into charger, took my dog outside, showered real fast, washed a few dishes, then came back in to room within 15 minutes to my phone being dead and hot. It's never got this hot before even while rooted and plugged in with this rom on it. I have never had it get that hot. Was just formatted the day before and really bare but, that is what happened.
A couple battery apps I had put the batteries remaining life capacity at around 60%. It held a charge poorly. Even for 60% capacity it felt weak, considering how little I did on it lately. I am thinking the battery may have took a crap but unsure because it warms up when it is plugged in. I plan on getting a battery soon since they are inexpensive and replace it to try it out.
Just wondering if anyone here has any experience with this and can offer any advice.
Thank you in advance.
(I looked for a min or two for similar posts but didn't find much. Will gladly take down if someone can point me the way)
You say your battery was already outworn, It may have died. I think you should try with a new battery, Or take it to a technician who can test the phone's hardware to see if there is anything else broken
i've only had one similar case with an s3, which would turn of at random % of battery. But when plugged turned on. I replaced the battery and it worked fine then

I really do hope that is what's wrong. I just ordered a battery. Thanks for the reply. I also got some little tools and battery door adhesive sticker. Wish me luck!
funny story....
The mic in my Nubia Red Magic broke and I sent that back to hong kong for repairs like 20 days ago. Before the Red Magic, I used this galaxy s7 edge my friend gave me. I gave it back when I got the Red Magic and told him to sell it or something. Not much later, decided to buy it back off of him for $200 to give to my mother. She loved it. I had the gs7 edge with me exploring prepaid provider options for my mom when the Red Magic mic broke. So then I decided to borrow the edge from her till my phone got back and few days later I break this one too..
I feel naked without a phone for so long haha

I have the same rom, with charging issues. I don't think its the rom causing it. The s7e are getting old and the batteries are taking a toll with the age. My phone will charge up to 81 at night and stay there. I get better results with wireless charging so i just top my phone off during the day with my wireless charger. There is a code to reset the battery's internal memory, if i find the link on how to do it I will post here for you.

Thanks for reply and alright let me know if you find out. My phone had no problem charging to 100% Its just the 100% on the status bar wasnt 100% of the 3600 capacity from wear. My friend's also does the same thing as yours except his he cant charge more than like 24% haha. He just uses it as a plugged in music player in car.... I am getting battery in the mail tomorrow and will see what I can do.

Try this: https://forum.xda-developers.com/showpost.php?p=74268596&postcount=4
I have not done it because it requires draining the battery and I never get around to doing that. Hopefully it will help you out. Good luck!

A little late, sorry. lol.
Thanks for suggestion, however, I may have worded my statement incorrectly. I meant to say that My phone would charge to 100% and the status bar displayed it as 100% but, the health and total capacity of the battery in mah was not the maximum 3600 or so due to simple wear and tare. It isn't apparent within any stock android feature however, battery monitoring apps like accubattery gather statistics after several charging sessions and estimate the current mah capacity. Mine was much lower than the default oem stated value of 3600. So my battery could be charged 100% but the 100% is really only 2400 mah lol. It was obvious either way by noticing that after my time using it and the previous owner's bad charging over night habits, that the battery was gradually needing charged more often lol..
I did read about the calibration method before when I was first looking into the battery issues. It seems it is more often done after a new battery is installed.
I screwed up a new battery install at the last second. I had to stop due the tiniest little round metal piece coming off from a very light swipe of my plastic spudger.
It was a very small wire connector piece. Unbelievably irritating. I didn't even finish because I doubt it would work properly. I beleive it is for the rf cable or something not sure. The red one on the left bottom side of the logicboard/motherboard whatever. There are three of them.
I took it apart and put it together a couple times prior to this and in a hurry it popped off and I couldnt find it. I couldnt find out the exact part name online so I could buy one and solder it back on. I did find a site/ supplier that has a plethora of them though. They are tiny coaxial connectors/pins. I didn't look through them all but there are 6,000 some listed under coaxial connectors (RF). https://www.digikey.com/products/en/connectors-interconnects/coaxial-connectors-rf/437?k=coaxial pin
I haven't gotten around to asking samsung or the digikeys support if they could help me find out which it is. They have different sizes and frequency ratings or speeds and such. The phone is packed away until I manage to figure out which pin to buy or if I pull 80$ or so out of my behind and buy a whole new motherboard logic board haha.
