My Nokia 6 has the following issue , when 4G is open and the phone is not in use (just standby) the device gets high temperatures,
is that normal ? has anyone the same issue?
When it is on WIFI everything is ok.
This is normal with all devices especially if you stay in a place where the signal is bad or reflected. The fact that we see antennas signal as good, does not mean that the antenna sees us the same way. The radios of the phones need much more power to stay connected to the cell antennas than with a wifi router. When the connection is not that good, the radios of the phones tend to increase the output power. So, more power - more heat.
Thanks everyone for the info !!!
