My sg3 has been loosing power while plugged in and operating. This happened to my old sg3 and got a new one from my warranty. Suddenly it is happening again and I have no clue what's wrong, WITH MY BRAND NEW ONE. I have replaced the battery and tried everything. Can someone please give me some suggestions on what to do?

Just leave it there to charge,don't use it when charging,it is bad for your phone and battery.

Use galaxy charging current lite to check if it charges properly. I had the same problem and the I fixed it by buying a new charger

OK thanks

Charging problem

So I unfortunately ended up with the charging bug.
When I put my phone In the wall charger it doesnt want to charge. The charging indicators all turn on but I still lose battery.
I've tested the cord and charger on my friends phone and they work. I've also put in a different battery with the same result. Also booted into safe mode.
Help?

Replace the phone?
I've never had that problem, so have no clue. But if rebooting and pulling the barry doesn't do it, I'd take it to sprint.
What's the rating of charger u are using?

Stock charger my friend.
No apps because it started on the aokp job build 8. I switched back to stick rom but even that didn't help

Yes I think u r right but you see, we guys are not professional or experts. So we can only suggest some possible solution my friend.
And if someone is in trouble, these possibilities can lead him/her to the solution of the problem..
I hope u understand...

I would try reverting back to stock, and if that doesn't work, then i would get a replacement. Sounds like a hardware issue.

The same thing for me, some times the phone take all night long to charge 5%, and the phone don't charge, I got to switch between different charger, HTC Apple Samsung etc... It's very difficult, but I think it's the battery, it's just a simple supposition.

I don't think its the problem I think its the port its self but then if I connect to odin on laptop it shows up fine but won't charge from laptop

Same here

Try blowing some compressed air into the micro usb, could be something in there, if it's not charging at all it will be hardware related.
Another thing will be to check another battery iy could be the battery has failed for some reason, if none of those work flash stock and run triangle away to reset flash counter and it's off to a service center because it could be physical damage to the micro usb.

Charging but discharging

This doesn't make sense. My phone is charging but my battery is discharging. I've changed batteries but it's not the issue.
What could it be?

Some, if not all ROMs have a feature to have screen on while charging, is that what you're describing?

That's a weird situation, somehow your battery just isn't getting voltage. Get an external charger, they sell 2 batts and an external charger for less than $20 on amazon.
I approve this message.

I actually had the same issue when I first installed a custom rom on my s3. All I had to do to fix it was run a quick nandroid restore. Other's that I've talked to who had this issue told me to try different kernels, specifically kernels designed around battery life. Hope this helps

First remove rom and test as custom rom or root voids warranty anyway.

most probably your charging port is faulty. Try blowing air in the port and see if that helps. Or take it to the service center.

You need to factory reset. If it fixes it, its software. If not, hardware. You need to know so you can send it for repair

Just use others samsung charger to try, definitely faster than the original one. I have tested.
