Do Smartphones Really Charge Faster In Airplane Mode?

If you're a heavy-duty smartphone user — which
includes just about everybody these days, since
the average Nigerians spends 4.7 hours a day
gazing at and tapping that little screen — you know
how agonizing it is to have to stop looking at cat
videos for a while and plug your phone into a
charger to replenish the battery. And some phones
can take hours to charge.
But you can reduce your separation anxiety a bit
by following this tip: While charging, switch your
phone to airplane mode, so that the phone won't
slow down the process by continually burning
energy trying to connect with cell phone towers
and plot your location with its GPS function.
This trick actually works, and so dependably that
mobile provider Verizon recommends it. The
reason why is that while your phone is in its
regular mode, it's continually trying to signal cell
towers and pinpoint your location. And even
though your phone most likely has assisted GPS,
which calculates your location coordinates using
the cellphone network rather than satellites, the
function still burns up a lot of juice . That's
because the location-finding stops your phone
from going into full-on, energy-saving sleep mode.
When you switch to airplane mode, you turn off
reception of those radio transmissions, and as a
result, your phone charges more quickly. When CNET tested the proposition a few years ago, airplane mode shaved four
minutes off a phone's charging time in one trial,
and 11 minutes in another.
