S6 that was dead, battery reset didn’t work and didn’t connect to computer, Green LED tho. Waited until the green led turned red, plugged it in a computer and got the battery display, no charge tho. Plugged/unplugged about 5 times rapidly and got it started charging. Did a factory reset and had it working for about 1 day. Plugged it in to a charger with about 80% battery while i was browsing. Then suddenly 3 quick lines across screen and it died. Got it started again directly but it died again a few seconds after. Now completly dead, black LED and nothing happens when i connect it to computer. Is it worth to change the power ic? Battery seems fine, i might suspect my brother used another brand of charger to the phone.
Are you using the Samsung charger cable and plug in adapter that came with the phone? check the condition of the cable and make sure it’s not damaged. Was the phone ever dropped or liquid damaged? could the phone be damaged inside? Could it be the charging port is loose/damaged inside?Was the battery, or any part for that matter, replaced recently? Have you tried charging it directly through an outlet instead of through the usb port on a pc/laptop? Is the Android OS up to date?
