5G➡️4G

[Kitti248]

Can anyone tell me why the Samsung S24 device automatically transfers from 5G to 4G networks when the device is in hot conditions?

It's for extension of battery health 👏

How can i turn this off (extension battery health) it is a setting in device or Samsung implemented it by own?

Samsung devices automatically switches from 5G to 4G primarily because of poor 5G signal strength in the current location, which can happen when you're at the edge of a 5G coverage area, or when the phone prioritizes a more stable connection over a potentially faster but weaker 5G signal; this behavior is often managed by the phone's "Smart 5G" feature to optimize battery life and network stability.

How can i resolve from this issue? Cause i use more mobile hot-spot for PC and want better network coverage.

Do not charge while using a hotspot
And try to keep the phone in cool conditions
May be external cooler or simply keeping in front of Fan or AC

[Clasto24]

If you want to charge anyway, use USB tethering and turn off fast charging

Look if you go to Setting > Connections > Mobile Networks ; then you will see the option i.e. network mode for sim .
It will be automatically selected for 5g/lte/3g/2g(auto connect) and sarcastically you can't change it to 5G only. So that in my experience there is no option to keep 5G only mode active in flagships also. You have to go with this.
In an other scenario
Airtel sim have NSA(non standalone i.e it will fluctuate from 2g to 5g depending upon networks) 5G so fluctuations are frequent but Jio have SA(standalone i.e only 5g if the network reception is good in your area otherwise 4g) 5G So the fluctuations may be minimal but is there...
