How long does your battery last? I have heard it drains very quickly?

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.

  Wow. 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?

    Not 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

    I'm not entirely sure if modem sleep was used in that 24 hours calculation.

      I'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.

    Well 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."

      Neat. I had no idea it could improve that much.

  Amazing. That's 4x what I get on a Pixel 3. :)

    Standby, not screen-on time

      When I first bought a Moto G3 for my dad, before I got a sim for it, or connected it to wifi, I left it on, it lasted a week

Lasts about a day, but there are further software fixes on the way to enable lower power states. Really excited to get usb host working, pecking away at the touchscreen (with no haptic feedback yet!) was getting very old very quick.

The first night I had it, running UBports OTA-4 (the latest at the time), I charged it up to 100% and roughly 12 hours later it was <30% with the modem disabled. Battery life is not anywhere near what you're used to on Android or iOS because in addition to SoC suspend functionality, the wireless/cellular drivers also need work re: sleep.
