red x on battery

I had the red x problem with my tab 12.2 even though I was using original/correct 5.3 volt charger and cable (compared to Galaxy Note 4's 5.0 volt charger). The solution that worked for me;

With tablet on and unplugged, hold down power button briefly enough (so not to turn off tablet) to plug in cable, then release power button. No red X. The bummer part is that I need to do that every time I want to plug in power while using. Luckily a very simple solution, but it would be nice if it would just work plugging it in. For me... it use to be able to charge just plugging in, not sure what made that change.

Red x problem tried everything only thing that work is the turn off then plug the charge in and it charges .Samsung should fix this soft wear problem

The red x means that you are trying to charge with a charger that reads as a usb cable connected to a computer. So its either you are charging through PC or you need to change the charger

Masalah red X battery tak boleh cas

maybe your battery is weak you need to replace it or try to reheat the ic inside the battery upper head its der the ic of the battery

The red x on a Samsung device means that you charger is broken and it will charge way slower.
