I don’t think you’ve used anything but a Boox in a long time, and have forgotten what the standard is. Boox has 1/10 the battery life, takes forever to wake up, and doesn’t support deep sleep properly (so it either drains battery when sitting idle, or shuts off entirely taking 5+ minutes to power back on). It’s decent hardware with very badly designed software. Neither Kobo or Kindle devices have these problems, they have battery that actually lasts, deep sleep when idle for any length of time, and power back up, even from deep sleep in 10 seconds or less.
