nothing to do with that, but to do with people who use their phones a lot.
say i have to drive for 2-3 hours in a day, that means i will have my bluetooth connected to my head unit for that amount of time. now say i have to use sat nav as well at the same time. my battery used to get raped on the stock kernel and rom, and i would have to charge it halfway through the day. now i no longer need to. that is why i wanted the phone to operate more efficiently. also use 5g wi-fi at home which eats the battery up on stock.
the more time you get out of the phone, the more useful it makes the phone in long journey situations or even when your bored, playing a game would decimate the battery, now it still does but not to the same extent, im talking proper games like gta, need for speed, etc not paper toss.
What is this 5G you keep talking about?
