samsung s3 charging issue

[Ookakiba]

So recently my Samsung s3 has been having issues with charging and im not sure what to do. When plugged in it either charges slowly or shows that its plugged in, but doesnt charge. Sometimes I have to play around with the cord to even get a charge. Ive tried multiple charges but its the same thing. Could it be a battery issue or something else?

How old is it? It is entirely possible that its battery has reached the end of its useful life, and needs to be replaced.

Have you completely powered-off and reset the phone recently? If not, do that.

i agree with onus or it can be software issues sometimes to reload OS can fix the problem.

It could be that your charging port connector is bad. I have a Note 3 and it does the same thing with the factory cable. Even if it's plugged in, it'll believe it's a non-factory charger and won't charge at the full speed it should. However, if I use a non-standard cable it charges just fine at full speed and gives me no crap.

My suggestion: see if another micro USB cable will work instead. Downloading a charging monitor app (I use one called "Charging time") and see how much voltage is going to your phone. If it's only 300mA, then it's likely the cable connection to the port connector is bad. It could also be a battery issue, but I doubt it.

The S3 is old enough that I suspect the battery issue. A cable problem is possible, but near-daily charging for three years would have hit the 1000 cycles that most Li-Ion or NiMh batteries can handle.

Hard to say, honestly. Could be both. :-/

Ive had my phone for a year and a half so, its fairly old. Ill see if somebody I know had a spare battery and try it out. Also ive tried multiple cords and they all have charging issues.

Ive restarted my phone and the issue is the same. Perhaps recovery mode would work? What would i do if the charging port is bad? I assume replace it.

You can replace the charging port, yes; however, bear in mind that as soon as you do, you breach whatever warranty you may have on the phone. You may also be charged if you're on a contract and go to turn it in on a new one. If you've got insurance, just get another one. If not, you're either stuck with it, you buy a new battery, or roll the dice on replacing the port. From what I understand and have read, it's a fairy straightforward task and is a known issue by Samsung yet they've done nothing to resolve it.
