The article is crap, but it is correct in that you don’t need to use airplane mode. I would, however, advise to still use it purely to preserve battery life of your device as otherwise it will very aggressively keep scanning for networks and drain it.
Yep. I do wish there was a toggle for the cellular radio by itself (rather than just mobile data). It’s annoying to have to go airplane mode then turn WiFi and BT back on.
I don’t but I’m running an older Lineage OS. Is it in the quick actions on the notifications pulldown?
Weird. On iPhone it remembers if turned BT and WiFi on while Airplane mode is on and will only turn off the Cell antenna. Do that every time I travel.
How old are your phones? I don’t notice any “aggressive scanning” when I don’t have airplane mode on. The other user is not able to switch WiFi on in airplane mode, my last two phones did that no problem and they go like 4-5 years back.
Cell towers, without mountains/buildings blocking them, reach 10+ miles and airplanes don’t fly that high… so you are within range of towers while flying unless you’re over the ocean.
However, connecting to a tower that far away requires running the radio at maximum transmission power which absolutely kills your battery. Also the towers reject your phone’s attempt to connect because they are programmed to ignore distant connections when they know a dozen other towers are within a few miles of that tower. If you’re flying over remote areas where towers will accept any connection you might occasionally get enough signal to call 911 but i likely won’t be a usable data connection due to how far away you are.
Wether it shows a connection or not, your phone is still reaching out trying to connect and doing handshakes with towers on the ground.
“You have a reminder set for 5pm today,” my phone said.
“A reminder? What is it?” I asked.
“It’s a notification to ensure you don’t forget something, but that’s not important right now,” the phone replied.
Then I remembered I’d left it in Airplane! mode.
😆 It might be nice to have a phone that tells me “Remember, we’re all counting on you. Good luck.” Otoh it would probably keep calling me Shirley.
You can absolutely do that with a text to speech app and the app Tasker on Android.
I think it’s still worth doing so your phone isn’t rapidly trying to connect and disconnect from nearby cell towers as you ascend and descend. Maybe there’s already protections in place for this case but it makes sense that it could add a lot of unnecessary strain on certain cell towers.
It’s been a long time since I’ve flown on a plane without at least a USB port to plug into, most have had full outlets to plug into lmao
Uneducated writers thinking using phone during flight is the same thing as using phone on the ground. It’s not.
Phones won’t interfere with sensors and stuff on airplane. That much is true. However pilots need to communicate with all kinds of airport staff over FM radio and there, since it’s an analogue signal, phones can cause that familiar disruption. It won’t destroy equipment, but you will annoy pilots and might prolong departure time. Same thing when landing, you are coming from no signal zone and all of the sudden 100 phones starts talking at the same time when pilot is receiving instructions from the airport.
This is why you can talk during flight, but not takeoff.
I put my phone in airplane mode if for no other reason than if it’s constantly trying to connect to a signal or Wi-Fi, it drains the battery way faster.
That disruption is from a 2G/GSM handset. Those networks were turned off a decade ago.
Pilot here. Still on the A320 series it’s obligatory to turn off the electrical devices for low visibility approaches (ILS Cat2/3) as aircraft’s navigational systems are not protected (at least certified) against RF interference.
Stupid article.
As of Jan 31, 2024 any planes still not hardened their altimeters to meet group 4 performance are restricted from flying auto land, I/II ILS ; and for the most part the airlines still flying them aren’t using those planes in US airspace. It doesn’t mean that there aren’t any flying just that when they are they’re restricted by the FAA as to how they can operate.
General observation.
As people lose more and more real freedoms [lower real wages, more crowded roads, small retail stores swallowed up by mega-corps] they cling to false freedoms. They will keep those phones on, because it’s their right to, dammit!
Can confirm. I own a pair of noise canceling earmuffs (meant for sport shooting; my dad was into guns). They’re completely unshielded so I can pick up interference from all sorts of signals. It’s fun to switch my phone between different networks to hear what 2G/3G/LTE/5G sounds like. I can even hear WiFi and find the dead spots in my house.
Point I’m making is that GSM is still sticking around here as a backup so when I drop my phone to 2G it sounds exactly the same as it does in this video.
There was GPS signal, it’s just by design that chips are not allowed to lock at above certain speed to prevent military use. But even if there’s no signal, mobile phone will try to find tower. If it doesn’t find one it will try increasing transmission power.
But even if there’s no signal, mobile phone will try to find tower. If it doesn’t find one it will try increasing transmission power.
Thus draining the phone’s battery much faster.
Same thing happens if you are camping in a remote location with weak or non-existent coverage.
What? Every smartphone I can remember owning has gotten a GPS signal if I hold it up to the window. Plenty of planes have GPS on board too. If there is a speed lockout, a 737 isn’t enough to break that threshold.
Last time I flew, there was no signal at all while flying.
There’s a number of factors that lead to that.
-
The cell base station antennas have a relatively narrow vertical beamwidth and are typically aimed a few degrees below horizontal. (Aircraft tend not to operate at that altitude)
-
usable range of each cell base stations is typically <50 km.
-
Cell base stations are optimized for communicating with mobiles moving less than 90km/h.
Given all that, if you happen to get a signal, you’ll be handing off between towers far too fast and too frequently for the network to reliably deal with.
I used to turn Airplane Mode on during my LSD trips many years ago, pretty useful.
