This is why phones should go back to having their batteries replaced easily. Companies are not into this , however, as they would rather you buy a new one. Remember Apple getting caught for slowing your phone with an older battery hoping you would just upgrade it?! Bring back replaceable batteries!
I watching this on my Nokia 2.2, which is have replaceable battery, this is my second battery after I bought this phone, but the performance is way below need 😅
Thing is, those exist but mostly only for budget phones. Medium-spec and flagships are both built to be "disposable" thus the batteries tend to be a pain to access and remove.
Easily replaceable batteries aren’t all good though. When you can easily expose the battery you’re risking the battery’s safety. If you drop your phone you’re very likely to accidentally break the cover off and your battery gets damaged and/or falls out. Dropping your phone is inevitable. Accidents happen and many of are very clumsy. No case can save your battery if it’s easily replaced. There’s no good solution to this. All possible solutions have cons that outweigh the good. At best they’re decent options
@@No_Direction-99 I disagree, removable batteries are the way to go. Remember the Galaxy S5 or the Galaxy Xcover series, a phone with drop protection, IP rating and a removable battery.

The one thing that I'm surprised you did not mention is fast charging. Excessive heat can ruin batteries, and super fast charging causes excessive heat. I've noticed that after using super fast charging for a few weeks, my S21 Ultra no longer take traditional charging, as it will now take 9 to 10 hours to charge. super-fast charging, which it'll do in about 50 minutes.
I remember they made a video of this years ago, I watched it when I was in middle school fascinated by how they work. Now I'm almost done studying electrical engineering at my college fully understanding it.
I've always used the rule of "never let your battery go under 20%, and never charge it over 80%," which years later ended up being the two percentages in iPhones that the battery efficiency mode kicks in or out, which I found cool!
Yeah but this is more of a myth, it doesn't increase your battery's life at all. This belief stems from the fact that batteries charge slower the higher the percentage of power is, notably at around 80%. This led people to believe that since batteries charge slower at around that percentage, that it must be because of some sort of mechanism that deteriorates the battery faster. But that's not really it. To better understand, you can picture batteries as bowls that you fill with water from a garden hose. The stream of the hose is powerful, and will fill the bowl fast. However, after the bowl is at a certain level, you realize that the stream of the garden hose is too powerful and ejects water out of the bowl, and you can never fully fill it, so you must decrease the power of the stream, and therefore take more time to fill the rest of the bowl. In batteries, the "water ejected" is energy being transformed into heat, this is why the phone gets hot when charging. But don't worry, the batteries (unless they are of dubious quality) can resist that heat no problem.
@@texanplayer7651 I use accubattery and I've heard from lots of reputable sources that most of the wear on batteries comes from the last bit of charging - mrwhosetheboss springs to mind. Please let me know how you think otherwise with sources thanks :)
I'm surprised they didn't talk about planned obsolescence, in which companies intentionally make their batteries to age faster in order to force consumer to buy batteries more often.
It is a missed opportunity… but to be fair it implies there is we way to make a permanent battery- which would not be the case even if the companies making them had working ethics.
This isn’t a thing with batteries. That lawsuit you’re talking about was simply because customers don’t understand how lithium ion batteries work and that they age faster with more use and more charges and age slower with less use and proper charging.

I believe its something to do with battery health. My battery health is currently weak on my 4 year old phone so it lost a lot of its initial capacity. Charging cycles can also affect the longevity of the battery cell.

Nope. The 3 R's are in order of priority. 1. Reduce - you don't need it in the first place 2. Reuse - it's not single use and get a new one, repurpose it again and you don't need to recycle anything or buy something new (see 1.) 3. Recycle - only if you can't reuse, divert it from the landfill and turn it back into raw materials to make new products but remember rule 1.
@@toolbaggersReduce isn’t the same as not needing it at all. For example, plastic around a whole set is fine, plastic around each product in a set isn’t.
Reduction in lithium-ion battery by moving away from automobiles and into transit-oriented development and human-centered urbanism should be our priority.
Yes, no way the world reserves of lithium (that we know until now) are sufficient for electric cars to help against global warming. We need walkable/bikeable cities and focus the lithium in good quality mass transport
My phone has been with me since 1st year college, now I am graduating in a month , My Cellphone battery is still the same or maybe it has been affected but just a little that I haven't noticed. The only tip that I will give you is charge it when it's 20% , and unplugged it from about 90-95%. Stop being addicted to it that you will use while charging😂 , just go to sleep or clean your house while its charging. Do the chores or go outside and touch some grass.
In order to get people to do these extra recycling steps, there needs to be an incentive to do so. People should be rewarded to recycle batteries the same way they are with aluminum cans or glass bottles.
I've heard somewhere that we could, in theory, make batteries using mostly hydrogen. Since it's a very plentiful resource, we could make a LOT of them and still be able to recycle them. I wonder what they would look like...
hydrogen batteries already exist for some EVs, its still very much in R&D but I feel like they would be way better than Lithium EVs purely because it doesn't need huge amounts of rare metals, just some pipes and a storage canister
4:02 isn't this outdated? it is highly recyclable and valuable like any metal. it is the collection that is hard because small batteries are stored at homes instead of being sent to recycling. EV batteries are definitely reused and recycled because they are large and/or valuable enough for the effort to collect.
@@huunter006 right but recycling phones has small value. What Apple is doing is actually removing/killing old phones so that people don't buy old phones and get the new
Phones get slower over time because of battery degradation, because to cope with the battery getting worse, they phone lowers performance to increase battery performance.
This is true for Iphones, for others brands, we are not sure. The other cause is simple the hardware not being able to run the newer and heavy software
My tablet battery is messed up, and in inconsistent ways. This morning, it went from 100% to 20% is 30 minutes while in low power mode. Sometimes, it will die at about 50%.
There should be a financial bounty on all batteries, that way there is an incentive to recycle them. Otherwise they'll all end up in the ground polluting our ground water.
If you want to save you battery, NEVER use it when it's charging and at 100%. I had a computer(with a battery) that was always charging and the battery is now 5 min from 100% to 0%.
Newer laptops have a feature where it doesn't charge the battery after it reaches 80%. It directly supplies the laptop with electricity without charging the battery.
That is entirely false for the newer laptops, which are any of those which are manufactured within the last 5-8 years. If used while charging, the battery is disconnected as it is fully charged, and now the power from the input source (your AC wall) is being used to drive the internal circuitry of the laptop, so your laptop's battery is left untouched. Some laptops even allow you to cut-off the charging after reaching a certain percentage. It's honestly very surprising and so abstract. I wonder the manufacturers should do some kind of inductions to let the customer know about these abstractions a bit.
I think I agree with Adam Something that changing all fossil fuel cars to EV's is not the answer. Use of trains for mass public transportstion is more doable.
What greatly concerns me is the way lithium is produced. I was hoping it was a step forward but it's not. Several companies are using vast amounts of fresh water to the detriment of the environment and the poor in countries that barely have enough fresh water for its people.
Correction: You CAN convert exhaust back into gasoline through carbon-capture and the process of creating synth-fuel. The process is just longer and drawn out than a battery, but scaled-up, it could not just reduce carbon impact, but reverse it. Anyway, back to batteries.
I have no access to those special recycling centers or drop offs… and the only bus here is to the casino and only 2 stops per town and only a few small towns and 1 city. I can’t drive and taxis don’t go out here. I also can’t afford to waste money on shipping costs to send something in. If I had access to recycling for electronics and batteries I’d do it but sadly I don’t…
Conventional current flow is in the direction of the electric field for both AC and DC tho, so… how do electrons flow out of the negative terminal of the battery? 🤔
It's a sad thing to see my phone gradually lose its battery capacity. I remember when i first got it, i could use the phone for about 3-4 days before it got on low charge. But i played some heavy games which heated up my phone like crazy, and now it works for far less time. I heard that the more the battery heats up, the more harm it does to the battery. Yeah, should not have heated my phone that much.
Same I don’t use too many heavy things on my phone besides RUclips but when I first got my phone it would last all day! Now it can’t even last the entire day anymore 🙁
Also since the batteries work on charges, having them charge completely full or null is a bad practice too as the electrons just move to one side causing disbalance
@@bansilalnabediya3501 I charge to 100% each night and the main reason is I am quite a heavy user especially of Social Media like Facebook and also the App called RUclips Any Smartphone that I ever have I can get it to last 6 years,I ONLY change it once every 6 years
The part about battery recycling being challenging due to the difficulty of safely extracting and reusing these materials is an eye-opener. It makes me appreciate the importance of developing more sustainable battery technologies and better recycling methods. On that note, have you guys heard about Chargie? Since keeping a lithium-ion battery at a high charge can accelerate its degradation, Chargie limits the charging to a healthier level, potentially prolonging the battery’s lifespan. Anyone tried something similar?
We as humans and society need to broaden our minds to more severe and urgent problems like environmental and mental health. That needs all of us, as individuals and as a society, to be less judgmental, more open minded and more willing to contribute towards the good. Enough of national and international needs. It's time to focus on humanitarian needs
For some of us, we just really need to maximize our device battery life. That is why I use battery limiters. Personally, I use this device called Chargie for my iPhone. Makes me ensure I only charge up to 80%.
Nicely made video with some important messages. But the main point (why batteries die over time) wasn‘t delivered very well. Why are the Li-ion “ships” veering off course? What are the mentioned ”side reactions”? It feels like the most important information was left out.
Here’s a simple way to explain: Li ions travel between the anode and cathode during charge and discharge cycles. But with each charge cycle, some li ions get trapped through unwanted side reactions within the battery. This reduces the amount of li ions that can move between the anode and cathode and thus less battery capacity.
i think this video contains the irresponsible framing that EVs are required to reach net zero emissions and that we need to keep mining lithium to achieve this. Lithium mining is extremely environmentally destructive and EVs are heavy leading to more road wear and tire wear which produces microplastic pollution. We need to drastically reduce the number of personal vehicles and invest in public transit, and leave as much lithium in the ground as possible. Reduce, then reuse and recycle
@@searchingforlostatoms7191 plastic polymers were all engineered with failure in mind. There are polymers that can hold up for centuries, others that break down in minutes. The value in plastic is precisely in the ability for the manufacturer to make it fail, and make it fail on a schedule. That allows them to make the maximum amount of profit from every ton of cancer they give the planet. Plastic pollution is the ultimate expression of planned obsolescence. It's not its own problem to be weighed in a vacuum.
As much i adore the concept of batteries and their recycling Electric vehicles are not the best or most cost effective way to help the environment As every civil engineer in the world know effective public transport is the only way
When phisicists first studied electriticy, they labeled the electrical poles randomly. After we discovered about the real flow of electrons, we simply defined that electrical current is on the opposite side of the electron flow.
Reaping power from impact is very interesting. We can find ways to get and store energy from the Earth's natural processes like earthquakes and maybe even billions of people's actions everyday like pressing buttons in an elevator or walking. If it is too hard or impossible to revert materials back to their pure state, finding sustainable energy alternatives is the next best thing humans can do.
I’ve bought a chargie to help me the battery life, i use it with success on iphone 14 pro max but I saw is also available for android, hope to help you…
technically, it is possible to turn CO2 and water back into gasoline through water-gas shift reactions and Fischer-Tropsch processes. It is simply not as easy as charging electrochemical battery.

hmm, the title of the video is "Why your phone battery gets worse over time", but then they only touch that topic for like 10 seconds using weird confusing analogy (ships and docks). They already explained the single use battery properly, why cant they explain the Li+ battery with the same detail as well. Everyone knows how battery works, I want to know what is the science that cause them to deteriorate over time (if the material never left the battery in the first place).

What do people do with batteries if they dont place them in recycling bins? Ive done that ever since I was a kid. Theres plenty of them in Sweden. Do other people just toss them in their household bins...?
Let's be realistic here people, most people (especially Americans) are not going to go out there way to recycle a battery by going to the a battery recycling company or returning it to the original company. Lost cause due to human laziness
I've had a camera (Canon PowerShot SX10IS) for a couple of decades. It uses 4x AA batteries. Yet, it wont accept brand new or freshly charged rechargeable batteries - it comes up with "Change batteries" every single time. WHY IS IT SO? Needless to say that it doesn't get a lot of use nowadays.
@@LynHannan probably the camera recognize a bad battery by reading it's resistance (it gets bigger when it's old), and as rechargeable have a different resistance than alkaline batteries, it gives the error, bad design
I wouldnt really say that taking batteries back is a bother since you have battery collection bins in every single supermarket. But anyway, interesting video!

But i played some heavy games which heated up my phone like crazy, and now it works for far less time. I heard that the more the battery heats up, the more harm it does to the battery. Yeah, should not have heated my phone that much.
Same I don’t use too many heavy things on my phone besides RUclips but when I first got my phone it would last all day! Now it can’t even last the entire day anymore 🙁
Also since the batteries work on charges, having them charge completely full or null is a bad practice too as the electrons just move to one side causing disbalance
@@bansilalnabediya3501 I charge to 100% each night and the main reason is I am quite a heavy user especially of Social Media like Facebook and also the App called RUclips
Any Smartphone that I ever have I can get it to last 6 years,I ONLY change it once every 6 years
The graphics are 🔥🔥!
The part about battery recycling being challenging due to the difficulty of safely extracting and reusing these materials is an eye-opener. It makes me appreciate the importance of developing more sustainable battery technologies and better recycling methods. On that note, have you guys heard about Chargie? Since keeping a lithium-ion battery at a high charge can accelerate its degradation, Chargie limits the charging to a healthier level, potentially prolonging the battery’s lifespan. Anyone tried something similar?
Thanks, Science!
another amazing video as always!
No it wasn't
@@toyotaprius79it was for us
@@toyotaprius79 Well ackshually it was a baaaad video 🤓👆
We as humans and society need to broaden our minds to more severe and urgent problems like environmental and mental health. That needs all of us, as individuals and as a society, to be less judgmental, more open minded and more willing to contribute towards the good.
Enough of national and international needs. It's time to focus on humanitarian needs
Same as us.
Our organs go old and die eventually.
You use, it wears..
We need to tackle next about the study of nephology
Again, your animations are tight 🔥🔥🔥👌🏾👌🏾👌🏾
Love your videos! Do another history vs!😊😊😊😊😊😊
Ted ed the best
Always wondered about that
'Nothing Lasts, Nothing Is Finished, Nothing Is Perfect' -WabiSabi
For some of us, we just really need to maximize our device battery life. That is why I use battery limiters. Personally, I use this device called Chargie for my iPhone. Makes me ensure I only charge up to 80%.
0:54 XD A bunny with a drum. Energizer Battery reference
Nicely made video with some important messages. But the main point (why batteries die over time) wasn‘t delivered very well. Why are the Li-ion “ships” veering off course? What are the mentioned ”side reactions”? It feels like the most important information was left out.
Here’s a simple way to explain:
Li ions travel between the anode and cathode during charge and discharge cycles. But with each charge cycle, some li ions get trapped through unwanted side reactions within the battery. This reduces the amount of li ions that can move between the anode and cathode and thus less battery capacity.
I’ve even taught lessons on battery drain for RC vehicles and somehow can’t process that my phone follows the same laws of chemistry and physics.
Even our body and photosynthesis follow them (electron channels and ion pumps).
It's wild how biochemistry is complex
Watching this ironically as my phone battery’s almost dead 😂
The Duracell bunny illustration is impossibly adorable and beats the original by a full charge...
Ironic, I had my battery damaged today, and this showed up in my for you page.
Hey Ted ed 👋 can you make a video on why some people have curly hair and some don’t? 🤷♀️ love your videos💗😁
Already ahead of You!
i think this video contains the irresponsible framing that EVs are required to reach net zero emissions and that we need to keep mining lithium to achieve this. Lithium mining is extremely environmentally destructive and EVs are heavy leading to more road wear and tire wear which produces microplastic pollution. We need to drastically reduce the number of personal vehicles and invest in public transit, and leave as much lithium in the ground as possible. Reduce, then reuse and recycle
I amswered 'Obsolescence - the efflux of time' before starting this video.
Planned Obsolescence, the second greatest crime against humanity that has ever gone unpunished.
I would give plastic a tie for the category of Environmental Hate Crimes
@@searchingforlostatoms7191 plastic polymers were all engineered with failure in mind. There are polymers that can hold up for centuries, others that break down in minutes. The value in plastic is precisely in the ability for the manufacturer to make it fail, and make it fail on a schedule. That allows them to make the maximum amount of profit from every ton of cancer they give the planet.
Plastic pollution is the ultimate expression of planned obsolescence. It's not its own problem to be weighed in a vacuum.
people would be encouraged to recycle batteries if companies that sold the battery offered a discount to swap the old one out for a new one.
The race between my phone's battery and the video's progress bar. Guess who won...
As much i adore the concept of batteries and their recycling
Electric vehicles are not the best or most cost effective way to help the environment
As every civil engineer in the world know effective public transport is the only way
And walkable cities
That earth animation is so so cute 🥺🥹🥹🤣
It's important to recycle batteries but only less than 5 % of batteries get recycled nowadays. Wait what?
Great. Dad pun near the end 😖
Me: Now that solves it.
My phone: 1% left
I always assumed the power ran from the positive terminal to the negative not the other way round.
When phisicists first studied electriticy, they labeled the electrical poles randomly. After we discovered about the real flow of electrons, we simply defined that electrical current is on the opposite side of the electron flow.
Reaping power from impact is very interesting. We can find ways to get and store energy from the Earth's natural processes like earthquakes and maybe even billions of people's actions everyday like pressing buttons in an elevator or walking. If it is too hard or impossible to revert materials back to their pure state, finding sustainable energy alternatives is the next best thing humans can do.
I’ve bought a chargie to help me the battery life, i use it with success on iphone 14 pro max but I saw is also available for android, hope to help you…
Remember when you used to be able to just pop your phone battery out like you can with a tv remote? We should go back to that
Another great video from Ted ed!
It gets wisdom though.
Companies dont want you to recycle, so blame them if earth destroyed...
Lead acid batteries, those things are great! One of the most recycled things on the planet too.
technically, it is possible to turn CO2 and water back into gasoline through water-gas shift reactions and Fischer-Tropsch processes. It is simply not as easy as charging electrochemical battery.
Wow now I know how a battery works and why they get worse over time
Why Lithium imagined as ship move from one side to another after leaving electrons?
Lithium ion Battery 🔋 Recharge and we need to Recycle ♻️ Battery To make Environmental clean
So why not recharge the NiCad battery in reverse polarity?
i came to get educated, I left with puns.
Wow thats amazing! Let’s save!

Huh. I never realized that was a real song. I've only ever heard the Kitboga parody. lol
Charge up to 85%.
hmm, the title of the video is "Why your phone battery gets worse over time", but then they only touch that topic for like 10 seconds using weird confusing analogy (ships and docks). They already explained the single use battery properly, why cant they explain the Li+ battery with the same detail as well. Everyone knows how battery works, I want to know what is the science that cause them to deteriorate over time (if the material never left the battery in the first place).
I've wondered.
this gives me knowledge

My battery just died and got replaced a month ago. I wish it was easier to replace batteries like in the nokia times. That way I can also have backup batteries which is better than a power bank.
This!
I had 2 and always had a fresh one waiting.
Now, I have a new Samsung that gets hot every time I use it. I took the phone clip (that attaches to the AC vent) out of the car to use in the house on a tabletop fan. Not so mobile now, am I? 😂
What do people do with batteries if they dont place them in recycling bins? Ive done that ever since I was a kid. Theres plenty of them in Sweden. Do other people just toss them in their household bins...?
Lastly I can at least give you a number 1
Let's be realistic here people, most people (especially Americans) are not going to go out there way to recycle a battery by going to the a battery recycling company or returning it to the original company. Lost cause due to human laziness
Well, I wasn't expecting this to turn into a video about climate change.
I cant wait for battery innovation especially carbon nanotube batteries just a bummer that we need to act NOW because the enviroment is falling apart.
I've had a camera (Canon PowerShot SX10IS) for a couple of decades. It uses 4x AA batteries. Yet, it wont accept brand new or freshly charged rechargeable batteries - it comes up with "Change batteries" every single time. WHY IS IT SO? Needless to say that it doesn't get a lot of use nowadays.
Probably a software error, were the sensors readings don't recognize the high voltage correctly
@@ElementalAer It recognizes non-rechargeable batteries just fine (so why shouldn't it accept rechargeables?)- I'm just sick of buying them.
@@LynHannan probably the camera recognize a bad battery by reading it's resistance (it gets bigger when it's old), and as rechargeable have a different resistance than alkaline batteries, it gives the error, bad design
1.5 volt cells have a 1.5 volt nominal voltage. Most rechargeable batteries only develop 1.2 volts fully charged.
I wouldnt really say that taking batteries back is a bother since you have battery collection bins in every single supermarket. But anyway, interesting video!
Not where I live 😢 they live in my house for years
that's cool, if only that's the case everywhere else
Where are these so called supermarkets you refer to?
First! And my phone battery is at 15%
Mine is at 97%
Lol i like the energizer bunny in the video
It represents every phone owner will die as well
