I have read that 2G uses less battery than 4G LTE, especially if I don't need much data.
Some sources :
Does 4G consume more battery than 3G if I don't use it for data?
Now, my question is : if I switch mobile data off, has the "mobile network" setting (2G/3G/4G) still an impact on battery consumption ?
The reason behind this question is that I am looking for the most battery-efficient configuration in my use case. Most of the time I am connected through Wi-Fi. Mobile data is switched off. Now, as for the mobile network setting, is there some kind of optimization to be done ? I'm hesitating between 2 settings :
- The default setting is 4G with VoLTE on
- Or would it be more battery efficient to switch VoLTE off, and activate 2G ?
