Find a way for people on 5G with low signal bar to drain less battery, or someone improve a way when using 5G it doesn't drain too much battery than normal, I know there's an option to choose which apps to run only by 4G + 5G but I'm sure this can be improved somehow...
Excellent suggestion, I lock mine to 4g and it is quicker in speed tests and uses less battery. Very rarely do i get a type of 5g signal that is as fast as the old 4g plus the 4g has full signal all the time so also uses less battery.
