100% battery but turns off once I remove from charger

[FrancesLey]

Note4 is fully charge, but then after I unplug it from charging it keeps on turning off. Coz it does turn on just until when the Samsung logo appears then it'll turn off. Then the cycle goes on. I bought my phones battery just few months ago.3 or 4

Well it could be a bad battery, especially if it was an aftermarket battery.

Try the following and see if it will turn on.

1. Remove the battery.
2. Press and hold the "Power" button for 20 seconds.
3. Now put the battery back in.
4. Plug it in to charge and allow it to fully charge before turning it on.

If this doesn't help, then test the charger cord to see if it is good. Either try your cord in another device, or try another devices cord on your device.

Should that not be the problem, then check the battery to see if it needs replacing.
