de0u I had 5G off in the past, the battery drain was 1.5x higher.
In the summer, abroad, if I had 4G on, the battery drain was sometimes going to extremes, 20-30% per hour, with 5G it was 2%. So I left 5G on, september, october were fine, spending about 12% of battery per night idling. Not sure what changed. I did not add any apps or alter any settings. Just the automatic updates happened
