Today my phone chrashed twice when starting navigation while on the car charger. Screen went black, battery charging icon appeared, red led showed. A second attempt gave the same result. I also noticed the LED shining red... was rather afraid. And decided to restart without the charger, start navigation, and no crash.
After unplugging the charger, the screen stayed on the battery icon for a while. I could reboot the phone with the power button.
It woked okay a few times before but maybe the battery charge state was different, or I started navigation before plugging the charger in.
So, I won't use that charger (Samsung CAD300UBE rated at 5V 700mA) again. But why would it crash? The phone running on just charger power (which is insufficient) and crashing - perhaps to prevent damaging the battery with shallow charge cycles? I estimate the charge left when this happened at 80%.
So be careful which charger you use. Does anyone have a similar experience?
Im having same issue, but my phone wont boot up.
Any fix?

Long story short after not using my Universal for a while it now has this issue:
Only turns on when plugged into charger
Immediately shuts off when unplugged
When plugged into charger, red charger light is not lit
When plugged into USB, charging light flashes quickly and unit does not power on
I hard reset and no change
Under Settings>Power it shows Main Battery: Unknown
What can I do?
buy a new battery?
Ya that's, of course, what I figured. just making sure this was not a known issue of some sort.
...if the battery I ordered doesn't fix it I'm coming after you for the $2.60 it cost me.
uuu...me so scared
Cheers!
99% it is a battery issue...
I was playing some games.. phone crashed. Now when i plug in the power the LED just flashes RED. Can't boot. I can still get into the bootloader but thats it.
I am rooted, unlocked, etc... am ****ting my pants right now. Any tips guys. Searched around the threads not sure what to do ? Maybe restore and RMA...:crying::crying:
actually now i cant even access fastboot... it shows for a split second and crashes out to blinking red LED
plug it in the wall, keep it ther for 10 minutes or so, then try to turn it on again.
This happens when your battery is literally out of charge.
Let it charge, the phone's entered the trickle charge mode because the battery is low. It may not recover and if it doesn't it means the battery is having an issue. From my reading of red light issues the solutions have been: let it charge because the battery is to low, it shorted so unplug and replug the battery, or to rma it cause the battery died.
Sorry guys skipped a boatload of details.... yeah the phone is charged...
I was playing games off the wall charger, believe me it has plenty of power. The light is blinking red can't do anything, no power up.
Either RMA or take the phone apart, disconnect the battery wires and reconnect them. There should be a guide somewhere, just look blinking red light of death.
Yup, blinking red led is a trickle charge mode.
Maybe the wall charger did not have enough power. Or the phone decided to discharge anyway.
What I am wondering about: if the phone gets back to life, is it empty or full (as in: switch it on without charging and see if it shuts off quickly).
Potential ways to handle this:
- wireless charger. The wireless charger does not pass through the 'red led' circuit but charges the battery directly.
- leave on trickle charge for a day. To trickle charge, that is supposed to be a slow process I think. Maybe someone can measure the current when it happens.
- unplug and replug the battery. This may reset the charge circuit or something.
- hold the power button down for 10 seconds. This will electronically disconnect the battery (but I do not know if it is a place that makes a difference).

This is a thread i created for all possible red led problems (4 in total)
. have a read... It should solve your problem
Has anyone heard of these problems before? The first one is that the back and menu buttons don't work. They don't even light up when its turned on. Second problems is the battery doesn't charge well, I will put it on charge when its turned off and it won't get to the charging animation and for example when its on and shows its charging I pull out the cable and its still showing as charging. Also the percentage of battery left was all over the place sometimes. I turned the phone off, when I turned it back on about (without the charging cable in) it went to the charging screen, so turned off again and on again, this time it started up fine but when got to the home screen its still showing as charging with no cable attached. When I got the phone the battery was completely flat, so he must have had some trouble charging it too (he supplied me with a black 1a charger rather than the white 2a charger they normally come with)
I got this phone off eBay so I am sending it back, it had a new screen put on it apparently they didn't wire up the back and menu button? as for what's causing the charging problem? I noticed there were interference type lines when I used the touchscreen when it was charging. I was able to charge the battery in this phone in my other working S4. There was a OTA rom update but that didn't fix any of the problems, I'm guessing they are hardware problems and not much I can do about them other than send it back?
I got an external Samsung OEM battery charger (EP-B600CEWC) with an OEM battery. The battery works almost perfectly, but has one issue.
When charging in the external charger, it actually charges quickly, EXCEPT it takes 11 hours for the charger light to turn Green. If I take the battery out of the charger after 2.5 hours or so, although the charge light is still red, it shows fully charged when placed in the phone.
When I charge the original battery that came with the phone, the charge light turns Green after about 2.5 hours.
Oddly, when charging the apparently defective charger battery in the phone itself, it charges quickly (1.9 Amps), and the LED on the phone changes from red to green in about the same time as the original phone battery. In other words, the battery behaves normally in the phone, but it does not behave normally in the charger.
Anyone understand what might cause the extreme delay with the external charger LED turning green?
So I bought the official qi wireless charging back plate for the S 4. When I charge it up wirelessly to 100% the little green light comes on with the message saying to remove it from the charger. When I do the light does not turn and the message does not go away. I either have to plug it into a wired charger or restart the phone to get it to stop.
I thought at first that it would go away after a little while once the battery drained down. I have played games on the phone for 15 minutes which should drain the battery a good bit and it will stay at 100% according to the battery stats. After a reboot it will show 90% and I know a reboot does not drain that much battery.
I have tried different charging pads with the same results. Anyone else have this problem?
Yes I get that also. I have Yinjeng receiver and one white ebay charger pad and one LG charger pad. With LG pad it's charging till 100%, with the ebay pad it goes to 100% and after I lift the phone I still have a green battery in the left side of Notification bar. And indeed I can use the phone and it stays at 100%. Only a reboot solve the problem.
So the LG charging pad doesn't cause it to get stuck like that?
Just noticed that when it is stuck like that and I plug it in to a wired charger it says 'Switching to wired charging' or something like that. I wonder what controls that and it is something I can reset.
