Stop Charging Your Phone at Night, Here’s Why


Your smartphone is effectively an mp3 player,
portable gaming console, TV, and netbook all in one small package. No wonder it needs a ton of energy to power
up; so its battery better be good. What can we do to make it last? Certainly not charge it all night long. It’s a basic thing – you want your phone
fully charged in the morning so it’ll last through the entire day away from the comfort
of your home. Been there, done that. And even with cutting-edge smartphones that
can charge to max capacity in a matter of an hour, there’s no guarantee that you’ll
remember to charge it in the morning while you’re in a sleepy daze. Advice to leave your phone unplugged during
the night may seem risky and counterintuitive. The worst fear here is that your phone will
charge down while you sleep and won’t see the dawn of a new day to wake you up like
you’re used to. Frankly, it sounds like a horror story to
me. But still, you can’t go against the word
of science. Leaving your smartphone on a charger is bad
for it. It’s bad for the battery’s lifespan. Most modern devices use lithium-based batteries. Even though they’re rechargeable by nature,
and made with this process in mind, they’re highly vulnerable to constant interactions
with high voltage electricity, like in the outlets of your house. Just imagine, if you’re leaving your phone
on a charger overnight every night for a year, it’ll spend more than 3 months total in
contact with raw electricity. This amount of stress on a battery will inevitably
diminish its capacity. You’d be lucky if your smartphone lasted
for a little over a year in this case. Thankfully, it’s not all that bad, because
manufacturers know about this issue and try their best to avoid the damage. For example, there are automatic switches
on your phone that’ll stop the charging process the very moment it reaches 100%. It seems like that would solve the whole problem,
but it’s not that easy. You see, when your phone naturally goes down
to 99%, the charging will start all over again. Your phone goes from 99 to 100 % charged,
and back, many times during just one night, and this too can degrade the battery. Another thing you might take notice of is
your phone charger. I know, they seem to be simple tiny plastic
gimmicks to convert energy from an outlet to a USB plug. But if you pay close attention in a tech shop,
you’ll notice some of them cost a bit more than others. Good, high-quality chargers have special chips
in them that prevent overcharging. So it’s advisable not to skimp on chargers
– this way you won’t spend much more money on a new battery or entire smartphone too
soon. And what about charging cables? They’re also not just pieces of wire, you
know! Cheap cables aren’t compatible with features
like a Quick Charge, which is available on most modern devices in some form. But in some cases, it’s worse than that:
a poorly manufactured cable could cause a short, and then your smartphone would be fried
on a whim. Oh, My order? Yes, I’d like fried smartphone, some fries
with that, and a diet cola please… Overall, it’s always advisable to use good
quality tech when it comes to something as expensive as smartphones these days. But even all these reinforcements combined
can’t completely protect your smartphone and allow you to charge it for as long as
you want. These small charges and discharges between
99% and 100% will still occur, and the problem with them is that they’ll heat up your phone. Heat is bad for batteries. That’s why it’s so harmful for your phone
if you leave it in a closed car in the middle of summer. It’ll be all laggy and slow until you cool
it down. A battery left on the charge may produce heat,
but from the inside of the phone’s body, which is arguably even more destructive in
the long term. You can always ease this detrimental process
by taking your device out of the phone case when you’re charging it, but that won’t
completely solve the problem. There’s also some other advice going around
the internet that I’ll have to disprove as myths, and nothing more. For example, you’ve probably heard something
about fully depleting the charge of your smartphone and then charging it to the maximum capacity. For the present-day, this advice is almost
completely obsolete. This is fair for devices from the past decade,
because they were using a different kind of batteries, which were based on cadmium instead
of lithium. These batteries had a real problem with memory. Not that kind of memory. It was more like the amount of charge was
memorized by the battery. If it was charged to 30% regularly, it’d
be easy to get it to that amount, but hard to charge beyond it. Have you ever gotten so lazy you can’t even
eat? Are you kidding? Well, that’s kinda what was happening to
those batteries. This effect was also called a lazy battery
effect – clever name, ya think? Any modern lithium-ion battery won’t get
lazy like a cadmium based one, so you don’t have to worry about that. As is the case with the notion that the first
charge should be a longer one – this is about cadmium batteries too, and based on
the same problem I just mentioned. For a long time, there was little to no major
breakthroughs in the ways we power our devices. At least no sensible progress. The power of batteries grew to accommodate
our devices, which needed more and more power; but the sizes have decreased, leaving less
space to hold the battery. So the advances in engineering new ways to
manufacture batteries haven’t stopped. Scientists and engineers promise that soon,
we’ll have another kind of lithium-based battery that’ll be able to charge in a matter
of minutes and last for more than one day. And that’s not the most insane new idea
on the list. Can you predict what it might be? Tell me about the battery of your dreams in
the comments. But now let’s move on. As you already know, wireless charging is
a thing now, but it seems like scientists are ready to push it a step further. One of their new ideas is to make battery
chargers that can produce energy from a Wi-Fi signal. The very thing that was making us spend the
charge of our smartphones, will also charge them in the future! And how about charging a phone with a sound? Using piezoelectric principals, tiny nanogenerators
will be able to transform the surrounding sound to electric power. Even your own voice will be a good source
of energy – charging a phone while talking on it? Yes, please! Guess that’d be good news for service providers,
huh. Scientists from Japan are in the middle of
a decades-long study that will allow replacing lithium ion batteries with sodium. The main difference between those elements
is that lithium is quite rare and expensive, while sodium is literally everywhere. It’s one of the most wide-spread elements
on Earth! And batteries like that wouldn’t only be
more efficient, but also cheaper. Another idea is to use literal sand in batteries. Not quite literal though, as this battery
will use silicon – the main component of the sand. Thinned down into nano-silicon structures,
this element will be much more efficient in a battery than the graphite that’s used
now. And now to more expensive stuff: how about
gold batteries? No, actually it’s nanotubes made of gold
in batteries, where energy transfers through the gel will be so sturdy that the battery
won’t ever degrade at all. With a battery like this one, you’d be able
to charge your phone however and for as long as you like. But for now, the best course of action is
to use good quality charging equipment, keep your smartphone out of the heat, and most
importantly, keep the charge in it between 30% and 90%. Don’t starve it and don’t overcharge it,
and your smartphone will serve you for years to come. Or until the new whiz-bang model that you
just have to have comes out! Hey, if you learned something new today, then

  1. If you buy a modern Sony, it uses intelligent overnight charging – it arranges charge so it is fully charged at a little before the time you usually wake up. This is much, much better for the battery than fast chargers. The Xperia XZ series, the 1 and the 5 all do this.

  2. My mate 10 pro I buy second hand smartphone 2016 now 2019 battery still work nice 😁 and one more I like charging overnight morning leave charging battery battery can alive 12 hour

  3. I have a 2012 samsung S3 my battery charges slowly with low quality chargers and quickly with high quality ones, been charging overnight from then and the battery drains very fast, but did from the beginning

  4. The battery has a set number of fully 0 to 100% charge cycles. Two 50% empty charges to full will equal to ONE charge cycle. Phone charge circuits stop charging at %100. Cycles of 99% to 100% is meaningless. This video is a mixture of true and false.

  5. My phone has an special li-ion battery

    putting the detector on not before and gate with charge locker. XD
    It still has a high hertz sound while charging at 100 percents.
    My phone has a battery that uses around 1 percent within 10 minutes

  6. have been doing it for almost 2 yrs on my Sony and its still fine check with people who use iPhones or Samsung

  7. So are we supposed to never charge our phone and have the battery die out the first time we use it and never use our phone again? xD

  8. That's ridiculous if you can't charge your phone overnight , what's the use of having all singing and dancing phones. Seems to me that the phone makers have never even considered how most people will and want to charge their phones. All that technology and they haven't even come up with a non over charging kit in the phone itself. RIDICULOUS DESIGNS!

  9. Been doing it for 4 years battery still going strong charging from 4% to 100% as for the battery that you've mentioned earlier there's already a phone that can charge from 0 to 100 in under 30 mins that could last a day it's the RealMe X2 Pro.

  10. **BRIGHT SIDE**
    make a video about: How to make your video & a studio tour video…… Make more videos technology…

  11. I am using mini nuclear generator for my phone i always have infinity charging i use this energy to charge my new Tesla car lol

  12. I heard before that this is not true, that if your phone got fully charged then your phone will stop recieving energy from the charger even if you charge it overnight.

  13. i think there should be a battery that has two parts one charges normally and the other part stores the extra 100% soo u can charge to full with no charger

  14. I charge my old iPhone 6 before and yes the battery ended up bad.its true..now I have iPhone X,now I don’t charge overnight..I charge before going to bed.

  15. Well it dont matter no more if you have an iphone because they is a feature on iphone called optimized battery charging

  16. I use only use the charges my phone came with. I do charge at night when I sleep but 8 out of 10 if I remember when I get up in middle of the night to use the bathroom. I unplugged my phone
