Why Phones Don’t Have FM Radio and 10 Rare Facts

Why Phones Don’t Have FM Radio and 10 Rare Facts

I think you’ll agree with me that smartphones
are sneaky beasts. They live a secretive life full of things you might not know… For example,
they have a radio built into them that — gasp! — can’t be turned on! Hey, I’ve got
a smartphone that likes to play hide and seek with me. I never find it where I put it down
— or where I thought I put it down. Anyway, let’s take a sneak peek at what is known
about this mysterious creature… 1. Why smartphones are so big?
Ever since they appeared in 2007, no-keyboard smartphones have been growing steadily bigger.
Currently, the largest smartphone doesn’t even fit into your palm properly, spanning
7.3 inches — that, and it’s also folding, bringing back memories of old flip phones.
These giants of mobile world are called phablets — a mix of phones and tablets. The reason
for this growth is that smartphones are becoming our primary computing devices, pushing aside
PCs and laptops. The mobile Internet connection is getting faster, picture quality is getting
better, so now we can do all the stuff we need on our phones. And that calls for bigger
screens that would allow to work with text more easily, edit images and videos, and much
more. 2. Can you get a shock using a charging smartphone?
While charging, your phone is connected to the grid, so naturally you’d be concerned
about a chance of getting electrocuted. Don’t fret, though: unless you’re using a counterfeit
charging device, you’re 100% safe. The charger transforms the AC, or alternate current, in
the grid to direct current, or DC, which is much weaker and can’t cause any serious
damage. But if there’s some problem with the charger’s insulation, the AC might get
into the DC part of the circuit, so when you touch it, you might receive a hefty shock.
So it’s best to only use original chargers. 3. Why does the quality of sound differ so
much in headphones and in the smartphone’s speaker?
It’s all the matter of size and distance. Sound is made by air molecules bumping into
each other and going in waves from the source to your ears. The bigger the source, the stronger
it affects the air, and so the louder and clearer the sound. That’s why the tiny speaker
in your phone will never rival those huge boxes they use at concerts, or even the speaker
in your TV or laptop. Headphones, on the other hand, are small but
still manage to provide amazing sound. That’s because they produce it right into your ears,
without the need to cover long distance between your eardrums and the membrane. And that’s
why, when someone listens to music in their headphones with poor isolation, you can only
hear that annoying scraping. 4. What is planned obsolescence?
It’s no secret that electronic devices are manufactured with an expiry date in mind.
But it’s not evil corporations deliberately making them last a very short time so that
you buy new ones every year. Every part of a gadget has its own service time, and it
makes sense to take the part with the shortest life expectancy as a standard. In a smartphone,
that’s normally the battery. It has a limited number of recharge cycles, after which it
stops working. As more and more phones are made with non-removable battery, you can’t
simply replace it, so manufacturers make all other parts of the phone match the battery’s
lifetime. Speaking of which… 5. Why are there non-removable batteries at
all? Technically, there still are, but they’re
swiftly becoming history. First of all, the conventional rectangular battery made the
phone bulky and, let’s face it, quite unappealing. The larger the battery, the more juice it
has, so this design was necessary for the phone to work long hours. Secondly, the back
lid had to be made of plastic for easier removal, and it didn’t fit the new trend for metal
and glass. Some manufacturers solved the problem, but that wasn’t all yet.
Yet another issue was that an extra layer of protection for the removable battery required
additional space, and that’s a luxury, given the miniature size of a phone. With a built-in
battery, this space could be used for cool additional features, like wireless charging,
for example. And finally, the rectangle shape was only needed for easy removal. Modern batteries
can use any shape instead, and sometimes they look quite weird. Step design or L-shape are
just a few examples of that. 6. How can a smartphone not overheat without
a cooling device? PCs and laptops all have extra coolers to
keep them, well, cool. Smartphones, on the other hand, can operate without any additional
fans. Their insides are built so that they can withstand a certain range of temperatures.
If your phone doesn’t get into the environment that’s either too cold or too hot, it should
be okay even if you use it to its full potential. The phone casing is also a kind of a natural
coolant that absorbs heat from the inside and lets it go to the outside. And finally,
the smartphone parts that generate heat do it in much less copious amounts than a laptop
would. Normally, it just wouldn’t be enough to overheat a phone. But you still can, if
you try hard enough! I’d strongly recommend not doing that, though.
7. How can a compass work inside a phone if there’s a magnet in it too?
As you probably know, the speaker needs a magnet to work, and that should throw the
compass off balance. But it doesn’t happen because the phone’s compass is adjusted
to ignore everything that’s built inside the phone. Manufacturers warn, though, that
any external magnetic force can still make it go crazy, so if you bring another magnet
close to the phone, its compass will show a wrong direction. The same can happen if
you walk through the security metal detector or put your phone close to an MRI machine
(which is also ill-advised). 8. Why don’t smartphones have built-in FM
radio? Actually, they do. Every smartphone there
is on the market has a built-in radio chip that can tune in to AM and FM radio, but the
catch is that it’s locked and can’t be unlocked without the service provider’s
and manufacturer’s say-so. There’s much debate about this, and in earlier smartphones
the chip was unlocked by default, so you could listen to radio (and still can, if you buy
such a phone) as much as you wanted. Today, providers argue that consumers don’t need
or want the radio on their phones — they prefer to stream podcasts and newsfeeds from
the Internet instead. Well, what do you do to listen to music and news? Radio or the
web? Let me know down in the comments! 9. How do smartphones know how much charge
they have left? A smartphone battery has a certain voltage
range that is tested at the production stage. During these tests, engineers detect the voltage
at the battery’s maximum capacity and check it all the way down to zero. Then they convert
these numbers into percentage and program the phone to show it on its screen. This way,
the phone will know that, for example, 4.3 Volts correspond to 100%, while 2.7 Volts
are 1%. By the way, the older the battery, the sharper its charge drops to zero. If you’ve
ever seen your phone turning off while still at 4%, now you know why.
10. How come smartphones acquire a GPS signal much faster than dedicated GPS equipment?
If you have a car with a GPS navigator, you probably know how long it takes to connect
to the satellites and give you your location. If you turn on GPS on your smartphone, though,
it’ll only take a few seconds to adjust and show you where you are. It happens because
a smartphone can use different networks to help it locate itself, such as cellular or
wireless networks. Dedicated GPS equipment, on the other hand, can only rely on satellites.
So if, for some reason, all the cellular and Wi-Fi networks suddenly shut down, your phone
will take as much time to connect to GPS as your car.
And a little bonus: Why do browser pages sometimes load in a weird way, only to correct themselves
in a few moments? We’ve all seen it: you load a page on your
smartphone or PC, it first appears very strange and basic, like it would look, perhaps, in
the 1990s, and then it kinda reloads and finally appears as it should. It’s called a flash
of unstyled content, or FOUC. This happens especially when you visit the website for
the first time, so it doesn’t yet have cookies to help you load it faster. The flash is the
content of the website seen in your browser’s default styles. It appears because the browser
hasn’t managed to load the stylesheet of the website in time, but it still hurries
to deliver. Let’s thank it for that, I guess. Hey, if you learned something new today, then

100 thoughts on “Why Phones Don’t Have FM Radio and 10 Rare Facts”

  1. I never use original chargers. I mainly use USB charging hubs, both car and vehicle, with the occasional PC connection.

  2. You can't get anything more advanced or faster than a Samsung Galaxy Note 4 or a LG G5 with a removable battery. There are newer phones with removable batteries, but they are very low-end and slow.

  3. Really old and worn batteries the phone turns off at 50% or even 75% (by then it only holds 5-10 minutes of charge)

  4. They lock the radio so we are forced to use data, increasing usage and billing. Yet another reason providers conspired to stop the distribution of BlackBerry devices, thus killing the company.

  5. No one:


    No soul ever:

    Bright side: you can get electrocuted while using your phone when it’s plugged into the charger.

  6. Okay the headphones vs integrated speakers are more than just common sense. That one shouldn’t be on the list

  7. 1:44 This is wrong. Those adapters reduce the voltage – and lower voltages have less power to push electrons into unwanted/unexpected places. 5V AC would be just as safe as DC.

  8. As a rule of thumb, most phones with a headphone jack have fm radio enabled. Just need to check spec databases like gsmarena if you want to be sure, otherwise apps like nextradio can enable it on most phones with headphone jack but with the receiver disabled.

  9. 7:15 I would like to have AM/FM radio on my phone. I've been listening to it for years & I don't want to search new stations & podcasts etc

  10. When hurricanes and earthquakes knock out cell phone systems, FM radio can save lives. All you need is a radio station and a charged phone. The radio would not use as much power as cell and internest.

  11. FM radio is a very useful feature when unlocked. In a disaster situation or when far away you may be able to receive information with no mobile connectivity or cost.

    FM and AM is free to receive unlike mobile-data/podcasts – and works over a much longer distance – because it is a Broadcast

    When Radio Broadcast is removed – people have to Pay to receive Any Information.!

  12. You can't get shocked from bad wires at the DC end, but you can get shocked from damages wires at the ac end or damaged circuitry.

  13. That explanation of why there is no FM radio in smart phones doesn't make sense. They have it in there but deactivate it because they think people don't want it? If they are going to include it anyway, they should have it activated and just allow us to use it or ignore it if we want to. There has to be something else going on there. Like the radio industry not wanting us to use that for some reason.

  14. In addition to the Data Charges, the carriers want you to stream for your music selection for data mining. Then sell to marketers.

  15. Web.. but only because the phone supports that..

    Especially on travels i like to tune in the local radio stations.. Gives me some insights.. What is the type of music the people in this country like? What is considered popular.. Plus hearing strange languages is always fun.. something you don't hear everyday anyway..

  16. Usually you’re right on track but this video, which feels more like paid propaganda from cell phone manufacturers (“Only use original chargers or you could get shocked! -my Apple chargers fall apart and fray exposing wires just as quick as knock offs but triple the cost LOL)
    You’re videos are usually always unbiased and filled with truthful evidence but I stopped this video after asking “What is planned obsolescence?” And you IMMEDIATELY say “Uh well it’s NOT companies making products that will go bad or be outdated forcing you to get rid of the old and buy new.” Who got to you? That is such. lie! 100% lie. There is admitted proof from Apple they did this. I had an iPhone 4 for YEARS. It was the best iPhone to date and I nw er had even a hiccup from that thing through iPhone 5, 6 and 7. Then one day Apple forced an “update” to their iOS and boom! Suddenly everyone’s iPhone 4s started messing up and having issues and they were so frustrating all iPhone 4 users gave up and switched to iPhone 7.
    Then Apple admitted that “update” actually had code in it to f’ up iPhone 4’s forcing people to get new phones. They planned to make the phone obsolete and did it. C’mon bright side, don’t YOU start corporate gaslighting your viewers. I’ll be watching

  17. I don't buy cellphones that don't allow you to use the FM radio. And of course the phone has to have an external jack. Streaming services have their uses, but I'm not going to pay to get them.

  18. Yes phones do have FM radios. This is a lie. It only works if you have wired head phones or ear buds in because the phone uses the wire as the antenna. Yes some phones have FM radio.

  19. I use both the radio and apps but would absolutely love it if there was a way to unlock the radio inside of cellphones and think its ridicules it is unlocked from the box

  20. cookies have nothing to do with how fast your site loads. browser cache and sometimes server cache will impact speed. after the first time a site loads, your browser stores some of that data, which speeds things up for subsequent visits.

  21. Apple: Removes headphone jack that 99% uses to "save space"

    Also Apple: Continues to add radio chips that 99% don't use

  22. Is this an Apple video that I'm too Samsung to understand? My FM tuner works just fine. It just requires plugging in a wired headphone jack which serves as an antenna.


  24. DC is not inherently weaker than AC. The adapter converts line current (120-240 volts AC for most places) to a much lower 5 volts DC. It's not the AC versus DC conversion that makes it weaker, it's the conversion to the lower voltage. The cord to your device only handles the low voltage – not much chance of getting a shock unless the conversion section of the charger was poorly designed… in which case, it's likely gonna fry your device LONG before it zaps YOU.

    The biggest issue with 'cheap' phone chargers is some of them can get really HOT, even if they're just plugged into the wall and not actually charging a device. It's why I advocate unplugging your phone chargers (both from the phone AND the wall) when they're not in use.
    That goes for car chargers as well. If you ain't using it, unplug it.

  25. I would like to have both, listen to radio for local news, contest, or events going on, then stream music or a special radio program.

  26. Who wouldnt want a radio on their phone? well i guess some ppl but men like sports talk, women like music, and men, good radio stations. Its better than just saying lets not give them an option, but still charge them like they have it.

  27. Kinda funny how the galaxy S5 had a removable battery, was waterproof, had a memory card slot, had wireless charging, had NFC, was durable, and was thin and light

    Planned obsolescence is definitely at play these days

  28. Plenty of phones have had fm radio. The problem is the frequency the phones use for communication is the mid to high end of UHF while fm broadcast radio is the mid range of VHF. The antennas in the phone aren't long enough to receive fm radio properly. So instead it utilizes the copper wiring in headphones as the antenna

  29. I listen to AM and FM radio almost every day. I would love the option to do so with my phone or pad. I also listen to mp3s and treat my phone and tablet like a cassette changer. Audio books and music all day long if I want it .

  30. I believe you misspoke as to why pages load faster after the first time you visit it. It would be more like cache not cookies….

  31. For the last tip:

    It is not cookies what it doesn't have yet, cookies are meant to retain user data and preferences, among other things, not stylesheets.

    Normally, files on a webpage are saved into something called the browser's "cache" so that in future visits to the website, the browser doesn't have to download all the files again but instead retrieve some of them from its "cache".

    So instead of saying that it has no cookies, one should say that the page has not been cached into the browser yet.

  32. My phone old had fm/am radio, even it had live tv with antenna including dual sim card slot and a flash light. Its called G-FIVE.
