Probably. I have to say, my 15 pros battery is so bad, on vacations I run around with a big powerbank all day long anyways... You can also select automatic swapping between data providers between your two active sims. Now at least that must take more power. But how much power does a standby connection not doing anything does? Only two sims at once cam be active btw. Voice and data can be configured seperatedly and everything works perfectly.
