Phone only charges intermittently when turned off topic

So about a year ago my charge port started burning every time I plugged it in, and in the drawer it went. A couple of days ago I decided to crank open the back cover and just replace the charge port myself and voila, it works. I've gotten it to turn on and I let it charge for hours, but it gets to about 14 percent after an overnight charge. As well as that, when I turn on the phone nothing detects it, and it certainly doesn't charge. When it does charge (which is when it is turned off) It charges for about 5 seconds then stops and starts charging again. I've looked for answers and all I am finding is restarting the phone, sending it back, or some weird process in broken English I can't remotely understand. I'm not really afraid of losing data but I don't want to re-do s-off and recovery as I believe I had trouble in the past. Is factory reset my only option?

My device charges itself? topic

Sometimes, my device charges itself. I mean the battery goes up from 4 to 5 without my phone even connected to charger. What makes it happen?

Sorrry for bad English and thanks in advance.

[Q] Xt910 charges only through USB( not wall ) topic

As the title indicates it doesn't charge via wall, but usb charging works perfectly , even file trasnfer.

What I've tried so far:

Factory reset
New battery
Changed 3 chargers, 2 of them were original - they work on other phones
Clean the usb port on my phone

Also when I have it hooked on wall, one battery app I have shows that there is some usb connection on the phone, but it still won't charge. Any ideas? Running 4.1.2

[Q] Play store charges 25 to host - any Free hosts? topic

I am looking for alternatives to the Google Play Store that does NOT charge any fee to host your newly created app.

Are there any out there?

Ya know, starving devs may not have 25 bucks.. (LOL) I look forward to your replies.
Thank You.
