[Q] Device Charges Only From USB Port, Not From Wall Charger! - Galaxy S 4 Q&A, Help & Troubleshooting

Hello guys,
I have a weird problem with me device, it does not charge with the wall adapter (rated 0.7A) and rather discharges while showing the lightning bolt charging icon. Right now, I am trying to charge it with USB port with some success. It is very slow though.

A couple of hours ago, my battery had dropped to 1%. I plugged in the charger, and I tried to switch on the device (which I usually do, and it has worked with no issues until now) so I could use it simultaneously. The device started and turned off, and refused to accept and recognize the wall charger. After trying all sorts of things, I plugged it into my laptop's USB port and it finally started charging. I charged upto 3% with USB and then tried switching to wall charger, it didn't work. SO right now I'm charging the device with USB and it has reached up to 18%. The charger still doesn't work. Any idea what's gone wrong with the wall charger?
Please help me out.

Try to charge with a 2A charger.

Charging issue

Last night at 12% I plugged in next to the bed with stock charger. The phone spazzed and started trying to open the desk dock. It was like plugging in and unplugging over and over again...fast. on top of that I've never used the desk dock so I don't think I triggered any settings.
I rebooted and changed outlets. Its still doing some strange things on the charger this morning. Plugging in, screen off the red charge light stays on for a sec then blinks off and repeats.
Not rooted.
Anyone got any ideas.

It could be your connecting pins in the phone. Did you try a different cable? If it wasn't the cable, then have you ever had to wiggle the phone around before the cable/dock connected?

Should've tried it already but ill switch cables and try again. I tried jiggling the cable. The connection to the phone doesn't seem as tight as the day out of the box that's for sure. Ill post back with findings.
Edit: upon further investigation I was too tired to realize that my daughters new puppy may be the culprit. Thought my awesome new phone had turrets for a sec, phew

Yup. That'd be your problem lol. But for future reference, try to line up the cable and the port and push it in once. When you can't put it in, you start wiggling it around which breaks the connecting pins. I've messed up a few phones like that lol.

Phone says charging, but no charging done. New connector.

The outcome was a little disappointing
So after 1 month of waiting, I received the flex cable+ usb connector + circuit board (all in one).
Disassemble/Reassemble.
* Phone still says (when plugged in): charging. But battery% goes slowly down. *
For months, the phone have been having problem with charging (or says charging but the battery doesn't really get charged).
Charging while phone off, charging with different chargers, charging with USB, charging with wall AC, charging with different batteries, charging after reset battery status, charging after CM10.1, charging after CM7.
Nothing works. Only putting batteries in an external charger works of course.
All hope for an internal charging was lost.
PS: As before, USB files transfer is fine, before and after repair.
I think there's a problem in the hardware
not in the software

that is a mainboard issue. i had the same one about an year ago. i've sent the phone to samsung bulgaria for service, they said it's the mainboard of the phone. they've replaced it, saved me 80$ for a new one, and the phone has been working like a charm for over an year. if your phone is still under warranty, restore its original firmware, remove any traces of root and send it for service. if you restore to its original firm and you get a charging paused. voltage too high notification then it's deffinetly a MB issue

Note 3 usb charging overseas?

Hi everyone I just have a quick question
Right now I'm overseas and the power voltage of this country is 220 v .
I forgot to purchase a wall adapter to charge my phone but luckily my cousins here all have note 3 's
Is it safe if I just plug my usb (that came with the phone) onto their wall chargers/aftermarket wall chargers ?
Here is a picture of my setup

This is very basic. You should always check the charger or any appliances if it has/supports 110V-240V input. Be vigilant.
All chargers have 110V-240V input range, and any usb charger can charge the phone. Check the output amps of the charger, if its lower than the stock charger then it will charge slowly, if its higher than the stock charger then it would charge fast but could damage the battery life as well. Otherwise any USB charger will works fine just after market cheap one may does short-circuit or over heat issues.
Thanks everyone

Samsung Fast Charge questions

Greetings,
I have a couple of questions about my wireless charger. Sometimes, when I remove the phone after charging the green LED on the charger stays on. Other times it goes off. When it stays on, the charger stays a bit warm. I am not sure exactly how warm but noticeable. Also, if I leave the phone on the charger after charging is complete, the battery on the phone stays at about 30C measured through Ampere. Is that normal or a bit warm. Thanks for any insight on this.

I just got the fast wireless charger myself. As well as the S7E (G935T). The last time I played with wireless charging it was a DIY mod to my Galaxy S3 using parts from a palm (treo?) but the charging was slow so it was a fun project but not nearly as functional.
I got the newer ##930## model wireless charger from Samsung, and I notice the phone get warmer vs the wired plug.
I wonder if using the wireless all the time would reduce the battery life of the phone? I'm guessing yes

Here's the wireless charger I use. It works through my ZizoBilt case ( similar to an Otterbox defender ). It charges about the same as a wired NON rapid charger. It definitely keeps up playing a video with the screen on max brightness.

bypass battery and run directly using charger

I've used this phone for a very long time now, since 2018
My current use case is using it as a hotspot and running some server and torrent apps on the phone, it works well, 24x7, connected to the charger all the time.
There are times when the battery does not charge for some reason and the phone needs to be restarted after the battery fully drains, especially when dowloading torrents.
I remember an older phone I had long ago, Lenovo Zuk Z2 plus, it used to work without the battery connected, directly connected to the charger.
I have a inverter in place so I don't really need the battery in the phone for my use case, I would like to use the phone like a computer connected to the charger 24x7, I was wondering if anyone knows if the Nokia 6.1 plus would work this way i.e without the battery connected?
I would like to save myself the trouble of opening it and disconnecting the battery just to find out.
Thanks.
anyone?
So, I opened the phone and disconnected the battery...
and...
It does not boot up without the battery connected with the phone connected to the charger.
Probably a jumper is required, anyone know how?
So, I visited a mobile repair technician, and
He tried direct soldering to the battery connector port, which didnt work
He removed the strip from the battery and connected the charging port to it and it didnt work
He finally, put it all ack together and removed the IC on the charging board, that controls the battery charging, now the battery is always charged at 100%
Just thought I'd share with the community
Ps- What he didn't try was a using a diode, but he said that wouldn't work either
