I don't get how idle power use is still so bad on competing products. I understand Android, at least, has improved somewhat, but it spent years being laughably

I don't get how idle power use is still so bad on competing products. I understand Android, at least, has improved somewhat, but it spent years being laughably bad compared to iOS, even on tablet hardware with no cell radio to worry about. Dead after three days in a drawer, while the iPad that'd been in there for three weeks still had plenty of charge left. WTF.
