charging problem - Samsung Galaxy A20 Questions & Answers

I have a Galaxy A20 that's stopped 'fast charging". Did a fac. reset and it worked...for a few charges, then stopped "fast charging" again. Another reset accomplished nothing. Have done some searching and nothing I've found, so far, has corrected the problem. I did see an article that suggested flashing the O.S. again, but I'm kinda wary of that. This problem is not uncommon among the Galaxy phones. So, anyone got any ideas before
I have to take it to a repair shop? Oh, the "fast charge" icon(in settings) does turn on/off, but when "on" and you plug in charger, it grays out???

Make sure you're using the correct charger that came with your device. (15W Adaptive Fast Charger If I am correct)
Fast charging can be toggled from within the Battery settings - If a charger is plugged in, you will not be able to toggle it unless the battery is Full at 100% then only will it allow you to switch Fast Charging ON/OFF while connected.
There's no harm in flashing the firmware again onto the phone. Just make sure its the correct country and version.

8125 stuck in Charge Mode. Overheating

I've been working on my friends 8125. First the original battery died and he couldn't charge it with the phone, so I performed the "jump start" trick with the 9v battery. That resolved the issue, but then he let it die again, and he jump start trick didn't work. SO the diagnosis was to replace the battery...
Well now that I have a new battery that works, the phone has somehow gotten stuck in "Charge Mode" and the moment I insert the battery it starts to overheat. This occurs before even turning the phone on. Once turned on the battery indicator shows that it is charging, even though its not plugged in.
I'm wondering if this is due to a hardware problem with the mini-USB port or something.
I searched the forums, but didn't find anything close to this issue so any idea will be much appreciated.
I'd say
that it was the battery. Try another one.
Overheating Issue
Being that it was already tested with a new battery and still didnt work, I would try to go into bootloader and reflash with original att or tmobile rom for the 8125.
I have the same problem, I've already re flashed the original ROM but still have the problem, any suggestions?

Weird charging problems

On a few occasions now I have plugged it in to charge overnight, to find that it has not charged, or only part charged. The LED starts blinking as it should, but the next morning it is still blinking and only gone up, say 10%.
Also on occasion, I plug it in to charge and although the LED blinks, the battery icon does not change to reflect that it is now charging.
Has anyone else had similar problems or, as I suspect, do I have a defective unit?
I have only charged and walked away from my device once (that I can remember) and for whatever reason it either failed to charge or was just charging stupidly slow. I ended up unplugging booting the device and plugging it back in again where it proceeded to charge normally.
Not sure if this is similar to what you describe but it is a strange behaviour while charging even if I have only come across it once so far.
Well, there's not much chance of getting a replacement any time soon, so I will just cross my fingers that it needs "running in". Will try rebooting also.
Thanks.
There are reports of this issue happening, indeed its just happened to me!
Youre not alone and afaik its not a defective device. If i find more info ill let you know

I can only charge mine effectively if I turn the Vega off, if not if charges for a while but then the light just goes out. If the Vega is off it charges fine.
There has been a lot of talk about the sub-standard chargers over at MoDaCo, I keep meaning to try and get a new regulated charger from somewhere and try that.
Maybe this weekend.

Well spotted, now I turn it off before plugging it in, it works fine.
Another annoyance is my screen brightness reverting to default after every boot. I have to go into settings and although the adjustment bar is at max, have to re-set it to max for it to apply. Anyone else?!

Sprint Tab says connect charger, no matter the battery level

Long time lurker, but first time poster. The issue started when I got the OTA Gingerbread update. For some reason, the update would not work, and I had to do the update manually. Every since then, my Tab does not charge correctly. No matter what charger I use, the battery icon always has the red x on it. It will charge, but takes a very long time, like I am charging via the USB port (which I am not). The other weird thing, is that no matter the battery charge level, on the lock screen, it says "please connect charger". I'm wondering if I can re-do the Gingerbread update and see if that will help. Any ideas?

I may not be of complete help, but it seems like a charging issue. I had a same message but that was because I charged via USB hooked to a computer. it continued to say to me to charge. So I rebooted and it was all fine. My tab is EU standard tab but I guess that either your charger is broken or your battery is completely confused about its status.
hope you find a better solution
Thanks for the reply. Right now I have it completely off the charger, and it's showing right @ 80% battery. But when you turn it off and back on, the lock screen tells you to connect the charger. Very odd.
Jive
did you read through the Battery stats clearing thread in this section? Might be able to help you out.
Also, check the accessories section, there are a couple threads about various cables/chargers that should help you with the red X issue. (i'm still waiting on one of the cables I ordered to find out if it does what it says, then I'll report back if it does.)

[Q] Charging Problem - Verizon xt907

Trying to fix a family members xt907 so here's the situation which has been nothing but headaches for me:
1. The Phone is only 7 months old and the bootloader is unlocked so warranty exchange is out of the question. She let the battery run down until the phone died. Then without charging the phone she turned it back on and it died again. From that point she couldn't get it to charge or turn back on while plugged in. At this point she brought it to me.
2. I got the phone and did a soft reset which finally got the charging screen to come up (showed the actual charging icon and the fill meter would flash up and then back down periodically). Problem is it never went past 0% after charging all night. I went ahead and tried to power it up thinking maybe it was just a glitch with the charging screen. Phone wouldnt boot. Just stuck at the Motorola logo. Another soft reset and the phone finally boots but now the battery icon showed a '?' and status showed '5% - Unknown'.
3. Performed a factory reset. No change. So I used RSD to flash the stock 4.1.2 firmware/kernel/modem, etc... What I found strange here is that despite the low battery Fastboot AP showed battery as OK, not low and let me flash (bootloader is unlocked, not sure if that affects low battery flashing or if that safeguard just wasnt built into the M).
4. So phone boots back up and shows 7% battery. Plugging in the charger at first notice has no affect. Battery stats shows '7% - Not Charging'. So I unplug the charger and the low battery warning pops up. Plug it back in and phone still doesnt register as charging, but says 'Not Charging'. Then I notice that the lockscreen shows '7% Charging'. Weird. Regardless of all that, the battery was not charging. The percentage never goes up and after reboots the percentage will remain the same. The battery does slowly discharge on the charger if I have it powered on.
5. I tried flashing a couple different roms before flashing back to stock and all had the same problem. I've formated /system hoping it was a problem with the OS but it didnt help. All of these charging tests were performed with the stock Motorola usb cable plugged into the wall charger. I tested the Motorola charger against my S4 to verify it works and also tried my Samsung charger on the Razr and it made no difference. However, booting the Razr M up with the Samsung charger resulted in the '?' in the battery icon and a notification in the status bar saying something about a CommServer starting. This notification was persistant and could not be dismissed. If I reboot the phone with the Motorola charger or no charger then that notification and the '?' dont appear.
6. I should also point out that I opened the phone up and disconnected the battery from the board and discharged the board. As a last resort I completely removed the battery and peeled back the tape on the bottom of the battery to expose the + and - terminals on the battery and wired it up to a stripped down charger and left it for a bit. Upon putting the battery back in the phone it showed a charge of 30% but still had all the same problems otherwise. So the battery is capable of taking a charge, it just wont take it through the phone, whether powered on or off. Thats what leads me to believe the battery itself is not bad. Its not practical for her to pull the battery to charge it, obviously. The phone detects the cable being plugged in and I can transfer files via usb cable to/from the computer no problem, so I'm fairly sure the Micro usb port is ok. Just refuses to charge.
A little lengthy but I'm at my wits end on this and really dont want to have her buy a $50 battery and then its a problem with the phone. I dont usually get stumped when it comes to fixing something but this one really has me. So if anybody can shed some light on this situation it would be greatly appreciated.

I presumed you tried to wipe the battery stats via the battery calibration app? not that I think it would make a difference. another option is enable/disable USB debugging. you could also try charging into a PC or a different outlet (perhaps that outlet does not provide a good current)?
not really sure, just tossing out some ideas...

I actually installed cwm recovery just to wipe battery stats. Im assuming it works the same way but I'll give the app a try. I'll try anything at this point. Tried your other ideas already though and didnt make any difference.
I appreciate the input. I'll give that app a try and see if it does something different from wiping battery stats in recovery.

Doubt it. However, the issue seems to be with the hardware, and since it is not a software issue, Motorola could honor the warranty. Last resort would be to unroot and see if you can get an exchange.

have you tried a non moto cable? the one that came with my fone was total crap, would continuously connect and disconnect when i hooked it up to my comp or try to charge it, so i tried my old samsung cable and i didnt have any disconnect problems at all. just a suggestion

Did you ever find a solution? I am having the same issues with my xt907.
What did you have it plugged in to? The fact that it said it was not charging indicates maybe you didn't have enough power coming through the charging port...

No. Verizon finally sent her a refurb replacement. I got the battery to charge up by taking it out and rigging a charger to it. But the phone still wouldnt accept a charge with the battery back in and it lost the charge it did have 2-3 times faster than normal. Battery Stats also showed the battery was showing a pretty decent voltage so unless the battery itself has a low charge circuit that gets tripped I'd be hesitant to point to the battery itself. And the charger port transfered files just fine and the phone recognized when the charger was plugged in (would go from 'discharging' to 'not charging'. So yeah, I was left stumped. Hopefully somebody else can get this solved for you.

Just an update: I ended up buying a replacement battery and it fixed the charging issue. I rsd back to stock. Then, playing around with it, I booted to bootloader and selected "Factory" and it immediately booted back to stock, but, the battery had a "?" again. Ready to throw the damn phone against the wall, I rebooted it. The "?" is mysteriously gone. What is the "Factory" setting? I think I tried it before, but had CM10.1 installed. My theory is that this "factory" boot from bootloader actually soft bricked the phone. Either that or the issue was truly the battery and simply replacing it fixed things. I am up and running now, cm10.1 is flawless, imho. Thanks for the quick reply and I hope this helps anyone with similar issues.
Beware of the "Factory" bootloader option...........
Here we go again. Upon a reboot into recovery. Recovery is twrp 2.5. What I notice is the motorola boot img takes an extremely long time (2 minutes) to turn off and cyanogenmod to begin. Could there be something corrupt in the bootloader? Is there any way to reload the bootloader on this device? Anyone have any ideas? Could it be Recovery?

[Q] Note 3 Will not turn on AT ALL

I have a Verizon Note 3 which I have had for about 2 months now, and today I was coming back from a cold trip and plugged it into the car charger via the stock USB cable, and the phone reported a gradual decrease in battery life, from 1% to 0%, indicating that the 12V connection from the car adapter wasn't charging it adequately.
A moment after it reached 0%, the device completely turned off. From that point on, I could not get the car adapter to charge the phone anymore. Thinking it was a limited volt connection with the car adapter, I gave up. Later in the day, I got home with the Note 3, and attempted to directly connect it to the wall charger via the stock USB cable, and to no avail nothing turned on and I did not note any activity.
I started troubleshooting by removing and re-inserting the battery then plugging it in, and that failed. I also tried with another regular micro-USB charger, for a standard Android device, not like the proprietary Samsung charger, and it did not work. Also, I tried connecting the charger directly to the device, without the battery attached, and that did not work. I even tried holding down the power button and home buttons for extended periods of time, but absolutely nothing flashed, beeped, and the screen did not turn on.
Please offer help, I need to know what else I can do.
I'm assuming you've tried just leaving it on the charger for a few hrs before trying to turn it on... Also, double check the connection between the battery and the phone.
Other than that, you've tried everything I would suggest. It is "possible" that the usb connection on the phone may be the issue. Next thing to try is walk it into a vzw store. I'm sure that thay have a spare battery to use and boot the phone up to verify that it charges. If it charges, maybe it's the battery? If not, it's equipment related and you need a new phone.

I have already tried to isolate the issue with the phone's battery, it seems as if I should be getting a notification or activity by just plugging the device in directly without the battery, but nothing appears even with that. Therefore, I have eliminated that it is an issue with the battery, and it is unresponsive with or without one. There would not be a point in leaving it to charge. I will have to contact either Verizon or Samsung customer support.
I had this problem happen to me before and I left it on charge for a few hours, I didn't touch the phone at all then all was good after a few hours.

I'll try it.
Customer Service
So I've had some time, and I first took the device into the Verizon Wireless store for support, and was handed a phone number to call. After a large amount of hassle over the account password, I managed to speak to a Verizon rep who told me that if I was to send the phone in after receiving the replacement and "user damage" was detected, then a $400-500 fee would be automatically applied to the account.
With no clear definition of what "user damage" entitles, he gave me the option to go to the Verizon store prior to the mailing of the phone and have the reps look at it there to determine any damage. If damage was not detected, then the reps would log it, and I would not have to pay the fee.
Does anyone know of the alternatives that Samsung provides? So far my experience with Verizon support has been sketchy, and a hefty fee is possible. Has anyone had any experience with this: https://play.google.com/store/apps/details?id=com.samsungadh.premium?
Otherwise, I'll see if I can deal with Verizon and have them send me a new device, then see what Samsung can do for me with their device repair.
What's being referred to as "user damage", is their suspicious that the usb port may have been damaged by you. Which is possible, I guess. Would have been obvious to you if you did it. Just to be sure, carefully check the internals with a toothpick and see if anything feels loose. If you think it might be, they're gonna say it's your fault. Did you buy warranty protection? If so it will cover that and will only run you like $100-150 for replacement.
♢NoteIII♢
Solved
It turns out I simply connected the device to my computer and let it charge and it seems to function properly. Now I have it connected to the wall using the wall charger, and I am getting a weird phenomenon of the battery percentage actually going down while the charger is connected and the charging icon is displayed. I will provide further details later.
Bad
Now it has gotten to a point where it will charge in the computer via the USB cable, but not in the wall with the same USB cable. It is odd, because the phone shows a charging icon but the percentage actually goes down. What is going on? Please help!
try another charger. like everything else they can go bad. eliminates it as a problem if nothing else.

Worse
The device has worsened to a point where it will not charge either through the computer or through the wall charger, and when I attempt to turn the device off while the battery is charging the screen flashes and a line appears, accompanied by a continuous vibration.
I never expected to have this many problems with the phone. Is it even the battery that is the issue anymore?

I'm assuming that you are not rooted? You need a new phone. But... you said u went to Verizon, did they do anything or stare blankly and point at a ceiling tile? It's possible the battery is borked. But yoh could only check that with another battery...which at the very least a store could do! Just plug in and see if it charges +1-2% with another battery. I only ask this cuz if you replace the phone, I don't think that they send a battery. Don't want you getting a new phone, same battery, and same problem. Just for s**ts n giggles, check that the telltale water damage strip on the battery is still normal...
♢NoteIII♢
god no
Oh no.......god no........the sticker on the battery has red Xs on it. I put it in a bowl of rice, the most I saw was dew on the front over the weekend, I did not submerge it or anything. I do not know if it was triggered prior to this weekend.
I was wrong
It turns out red X's mean that the phone is perfectly OK and no water damage has occurred. It is when the entire sticker is pink that water damage is indicated. This still doesn't solve my problem of it still having problems....I'll take it out of the rice and try turning it on.
status
To confirm, I am currently having a problem with the phone displaying the charging icon in the status bar and not actually charging when plugged into the wall, and instead vibrates every second and has odd orange lines and the screen flashes when the device is turned off and "charging".
When connected to the computer, the device has a RED LED light and displays the powered-off charging screen just fine. The device turns on fine, and charges normally, however with a gray charging icon, not a green one.
Another thing I noticed was that the battery went from 9% to 2% just in the time I connected the phone to the wall to the computer in the span of < a minute.
I had visited the Verizon store once and was told the store did not have the battery in stock, and I would have to call for a new phone + battery free of charge, as long as no user damage was detected on the returned defective device.
At this point, I am so confused to what is happening, I think you were right Lefty when you reccomended I should request a new battery AND device.
What jerks. There's a battery in the floor model. Oh well.
And to be honest it sounds like the battery is not the issue. You say it vibrates every sec or so? Sounds like the cable is not making a full connection. Kinda like it detects a connection. . Oh! Nope, no connection. Connection. Oh! Nope.
♢NoteIII♢
A little late (actually almost two months), but I have returned the device and above all of these other reasons it turns out the problem was actually in the software. When I went to reset my old Note 3, it turns out that it actually started charging properly after it was reset. Very strange, but a heads-up to anyone else having this problem to try that before you return your device.

Yeah I just tripped across this thread and was going to say to try to charge it in recovery/safestrap mode. If it's software related in the ROM, it would indeed charge in recovery mode
