00:22Amazing! See, so beautiful!
00:27Aashish, let's go home. It's getting dark. I forgot my phone. Please!
00:31Don't worry, Sanika. I charged my phone last night.
00:34I have a 7000 mAh battery. Don't worry.
00:37How many times do I have to tell you?
00:38You shouldn't charge your phone all night.
00:40It spoils the battery health.
00:42Leave it. Let it go.
00:45Oh!
00:46Don't let go!
00:50There!
00:54Rechargeable batteries.
00:55This small thing is everywhere.
00:57Look around you.
00:58Seriously, look around you.
01:00How many gadgets are within your arm's reach?
01:03Phone, laptop, earbuds, smart watches.
01:06All of them run on these ticking time bombs.
01:09Why am I calling them time bombs?
01:11Look at this.
01:21Although, a phone's battery rarely blasts.
01:24But, rarely doesn't mean never.
01:26Phones have exploded even when not connected to a charger.
01:30But, this doesn't happen all of a sudden.
01:33Batteries give some signs.
01:35With which, we can avoid this disaster.
01:38That's why, in today's Techno by Nazaria,
01:40we will understand the working of batteries.
01:42And, we will also know how to take care of them.
01:45And, how to know if your phone is going to blast or not.
01:49Lithium-ion batteries.
01:50Which are available in our smartphones, laptops, and electric cars.
01:54The system inside them is quite interesting.
01:56It has two layers.
01:58One is of lithium cobalt oxide.
02:00And, the other is of graphite.
02:01When we use a phone,
02:03Lithium-ions come from the graphite layer to the lithium cobalt oxide layer.
02:07And, when we charge the phone,
02:09we just push the lithium-ions back into the graphite layer.
02:13But, if more ions shift, then there can be a problem.
02:16Suppose, we remove all the pillars of a building.
02:19Then, the building will get destroyed.
02:21Similarly, due to more ions shifting, the battery can get damaged.
02:25That's why, manufacturers set a limit in the charging of the battery.
02:29Many times, the limit of half is set by the amount of lithium in it.
02:33So that, even after a full charge,
02:35half of the lithium particle doesn't shift.
02:38That means, technically, your phone can be charged more than 100%.
02:42But, we should not do this at all.
02:45Come, let's know what else should not be done.
02:48Overcharging or charging the battery below 0 degree can cause a fire.
02:53In both the conditions, the lithium metal builds up on the negative electrode,
02:57which can short-circuit.
02:59The protection circuit of your phone battery tries to stop it.
03:03But, it can fail at times.
03:05Do you remember the explosions of the Samsung Galaxy Note 7?
03:08The electrodes were so closed that a short-circuit happened.
03:12And, due to that, many accidents happened.
03:14By the way, you must have noticed that,
03:16after some time, the battery of your phone starts getting discharged faster.
03:20This is not just your imagination.
03:22This actually happens.
03:24We can understand this more easily in iPhones.
03:27The new iPhone shows 100% battery capacity.
03:30But, after a year, it decreases to 88-87%.
03:35Why?
03:36Because, in every 4 cycles, the battery loses its capacity.
03:39Every iPhone battery is rated for around 500 charge cycles.
03:43That is, after 500 cycles, you will notice that the battery drains faster.
03:48Because, the capacity of every lithium ion is naturally less.
03:52Just like our death is certain, these batteries also have it.
03:56If you have an iPhone 15, you can check the cycle count in the settings.
04:00For other iPhones, you can check it on the Mac with the Coconut Battery software.
04:06Android users can also check their battery life with different apps.
04:09There are major reasons behind battery degradation.
04:11Software and heat.
04:13Some apps drain more battery.
04:15So, we have to charge more.
04:17That means, the charge cycle increases.
04:19If you want to reduce the charge cycle, what can you do?
04:23Simply, keep the battery saver on.
04:25Or, keep the background apps off.
04:27Even while searching for Wi-Fi and network, the battery drains a lot.
04:31Like, you must have noticed that,
04:33your battery drains faster in trains.
04:37At such times, you should switch on airplane mode.
04:40If your phone is overheating, the battery will degrade faster.
04:44Heat is the biggest enemy of the battery.
04:46Because, liquid electrolytes in the battery start degrading at high temperatures.
04:52That is why the battery drains faster.
04:55On the other hand, the battery slows down in extreme cold.
04:58Because, lithium ions move slowly in cold temperatures.
05:02That is why, your phone's battery cannot give much power in cold temperatures.
05:06It is best to keep the battery in the ideal range.
05:09That is, ideal temperatures and ideal charge levels.
05:12Which are between 20-80%.
05:14This can extend the life of your battery.
05:17New iPhone models have a feature to stop charging at 80%.
05:22So, make use of that.
05:24And yes, never leave your phone on the charger all night.
05:28Because, when the battery is at 100%,
05:30although a trickle charge mechanism protects your battery,
05:34but it can fail.
05:36The trickle charge mechanism stops charging when the phone is at 100%.
05:40And charges only when the battery starts draining.
05:44But, it is not good to keep the phone fully charged for a long time.
05:48It is more dangerous to cover the phone while charging.
05:52Heat cannot escape due to soft surfaces such as pillows and sheets or the cover of the phone.
05:59This can lead to a major accident.
06:01That is why, while charging, the phone should be kept on hard and open surfaces.
06:06The phone should always be charged with its certified charger.
06:09So that, there is no danger of overheating and overcharging.
06:12To avoid heat, never leave your phone in a closed car.
06:16And while traveling to hot cities like Delhi and Nagpur,
06:19do not give it direct exposure to the sun.
06:22If the phone is hot, then it is best to switch it off.
06:26Always keep your phone's software updated.
06:29The upcoming bug fixes and security patches can save us from overheating.
06:34When the battery health is over, you should replace it with a new original battery.
06:39But for this, you should go to an authorized service center.
06:43We have given its explanation in this video.
