Eyebrows raised...that statement doesn't sound right. I expect that a device
I own won't drain its battery if I turn it off. GPS radio receivers draw
quite a bit of power, and 3G/4G transmitters probably draw even more.
If your statement about power-off were true, I would expect that phones with
even the biggest battery would drain within a week or two.
Battery removal works for (most) Android devices but Apple long ago decided
not to provide user-removable/replaceable batteries.
