Unable to charge my device
I simply turned OFF the device, disconnected the battery from the mains and waited for 2-5 minutes (placed the battery separate from the device).

Later cleaned the terminals with a soft cloth ,placed the battery inside and connected the socket .

Started charging the device i power off mode itself for some time and later when i switched on the device it was successfully charging the device.

Lucky it was removable battery.(else had to go for a genuine service center and deposit the device for some time )
