Airplane mode disables a device’s cellular radio, Wi-Fi, and Bluetooth — the wireless transmission functions. But many airplanes now offer in-flight Wi-Fi, and cellular access may be coming to planes soon — so where does that leave airplane mode?

Here in New York City, my primary mode of public transportation is the subway - or "underground" as it is also known.
Where I live, the first (or last) twenty minutes of my trip is above ground, on an elevated track.
However, the next forty-plus minutes of the ride take place deep underground, with no possibility of achieving a cell-phone signal - with my phone being in a constant "Searching for Service" mode, which can be a drain on the battery.
I have become in the habit of switching to Airplane Mode as we descend below ground (or when I enter the subway for my return trip home) and it has proven to be a very useful tool in helping conserve battery life - especially on days when I'm out for twelve hours or more.
Yes - in the beginning there were a couple of times when I neglected to turn off the Airplane Mode upon exiting the subway -- but after a couple of very irate, "Why didn't you answer my texts ? Where wee you anyway?"s from my wife...that no longer happens.

I am in a habit of putting my phone in airplane mode when I sleep and turning it off again when I wake up. Sure, I don't get messages and stuff, but nobody calls me after 7 PM, so it's actually nice, with the tiny 1530 mAh battery in my phone...

I use Tasker to do a lot of those things... it can detect when you plug in headphones, plug in the charger, etc. I have it set up so that when I plug in the charger and it's after 11:00 at night, the phone goes to silent mode. This eliminates the 3 AM BRZZZZZZ when someone sends me an email or I get a Facebook notification...
straspey — 2014-08-11T11:56:14-04:00 — #5
Unless I'm away from home, I actually shut off my phone completely at night before I plug it into the charger and go off to sleep.
(See: Do You Ever Shut Your System Down - Like At Night? )
I don't do social media (Facebook, Twitter, etc) and nobody is going to send me an text or email which can't wait until 7:00 AM the next morning.
Also - We still have an old copper-wire land line which is always on. Everyone - friends, family and colleagues - who, for some reason, might need to get a hold of me at 3:00 AM knows this - and if the phone rings at that hour, I will answer it.

I'd be really mad if phones stopped coming with this feature. I use Tasker to automatically put my phone into airplane mode at night, and turn back on in the mornings. I also use it a lot when I don't want people to contact me, but I can still use the functionality of the phone.

I don't have my phone rooted so I can't use tasker. I used to use an app called Phone schedule to automatically switch to Airplane mode. Unfortunately again with latest OS update Google has barred access to this mode by external applications. Saved me a lot of hassles of battery charging and disturbance at night.
Isn't it strange that TV show creators would have their viewers believe tha people can be tracked if they have GPS switched on. It is simply a receiver. How could it? But in similar vein they also have the viewers believe that one can hot wire a car under the dash and drive away, even ones which have ignition switch operated steering lock.

Tasker does not require root. Some plugins do, but I've never needed root for everything I do with Tasker. (Mostly managing audio volume based on what's plugged in to the phone or the time of day.)
pmshah1946 — 2014-08-11T14:52:11-04:00 — #9
Okay it may not need rooting but now I recollect that the trial period is simply too short for one to get familiar with the scripts. I also looked for some ready scripts just to study but found nothing. In reality I don't have the time to learn, understand and write scripts that work properly within the trial period. I have enough on my hands at the moment to get familiar with the Windows Power Shell as M$ has warned that a lot of the older CLI utilities will be discontinued.
wilsontp — 2014-08-11T15:46:45-04:00 — #10
Everything is GUI run, so it only takes a few minutes to figure out how to use it. It took me maybe half an hour to build my first, useful script. It monitors the headphone port and resets the phone's volume based on what I plug in: a line-out cable set the volume to full, a headset set the volume to about 40%, and with nothing plugged in, the volume would be set to about 3/4.
The trial period is only a week, but if you have a spare hour, you'll know whether it's worth the $5.
Anyway, we're getting off the beaten path, so I'll stop plugging my favorite tool.

You can still use devices on the aircraft — even during takeoff and landing — as long as airplane mode is enabled. You don’t have to power them off.
Careful. That's true pretty much in the US only and not on all airlines. It's not true outside of the US.
wilsontp — 2014-08-12T18:10:13-04:00 — #12
I think the rules are changing in the US. Up until recently, ALL electronic devices, regardless of "airplane mode" were to be turned off during takeoff and landing. This is just now changing, after the FAA has determined that there's no real risk of interfering with the communications equipment and flight instruments.

Everyone knows about the risk and harm of being exposed to the radiation of a cell-phone. Whenever my 2 year old daughter asks to play with my phone, I put it to Airplane Mode to minimize the harm.
So far, I find it the best outcome of being equipped with Airplane mode.

Thank you for your encouraging reply. Will certainly give it a go. One question though. There is something I need done with may be a tap or two taps. Do suggest if it can be done !
I live in India where the ambient light is bright to extremely bright. The screen is practically invisible outdoors. I wonder why no one has explored using the now defunct iPaq's transflective lcd. Anyway if I invert the screen colours everything becomes immediately visible and clearly legible, even in sunshine. Do you think a script could mange that ? I wish someone came up with an Android version of AutoIt. That would certainly solve my major problem.

I was wondering if there was a way to schedule the Airplane mode so that the phone goes into airplane mode at night and comes out of it in the morning itself!!
wilsontp — 2014-08-15T11:16:40-04:00 — #17
@hameedtweet1989 are you using an iPhone or an Android phone? I use Tasker on my Android phone, which is capable of scheduling events. I haven't tried it with Airplane mode, but the trial version is free for a week, so you can try it.
nsdcars5 — 2014-08-15T13:45:48-04:00 — #18
Urban legend much? If cell phones gave out so much radiation, they'd be illegal. :/ Unless your phone is strapped to your ear with phone calls all day long, I don't think it'll do much to deteriorate any part of your body.
wilsontp — 2014-08-15T16:04:00-04:00 — #19
Agreed. The FCC has very specific RF exposure limits... and all handheld phones fall way below those limits. The last time I researched this, no one has proven any link between RF exposure within the FCC's limits and any disease.

@wilsontp Thank you ... I will check it out and let you know!
