This was a thing before the crust firmware was implemented. With crust it should last up to 24hrs and when you disable the modem up to 100hrs.

- OneLeggedCat 6y agoWow. That modem is a hog. Do you know if there is still room for it to be optimized, or is this about as good as it will get?
- AsyncAwait 6y agoNot sure, but given that this work is extremely recent my bet would be that there's some room for optimiztion still, but probably not anywhere close to the 100hrs mark. My guess would be the modem is the most power hungry component of practically any smartphone and 24hrs is already in line with mainstream smartphones so any additional % squeezed would be amazing indeed. EDIT: Maybe 90hrs? https://news.ycombinator.com/item?id=23852043 https://news.ycombinator.com/item?id=23852043
- MartijnBraam 6y agoI'm not entirely sure if modem sleep was used in that 24 hours calculation.
- megous 6y agoI'm pretty sure it was not. Modem in sleep, according to datasheet, consumes ~10mW. Current state of the art power consumption of the whole phone without the modem on at all is 110mW. (this is the value on which the 100h figure is based on) So when the modem will be actually in sleep, it will not add much to the equation.
- AsyncAwait 6y agoWell actually looks like I was way too conservative with my original comment, apparently lots could be done: "The current thing on my radar is writing a power manager for the modem. :) That will improve the standby from 24h with the modem active to ~90h."

- OneLeggedCat 6y agoNeat. I had no idea it could improve that much.
- hellcow 6y agoAmazing. That's 4x what I get on a Pixel 3. :)
