Three Charging Mistakes That are Killing Your Laptop and Mobile’s Battery

Almost all of the gadgets and devices you use are powered by Lithium-ion batteries. From your phone, laptop to shavers and watches - batteries power them all. However, a significant portion of people is generally unaware of how to take good care of the batteries in their gadgets right way, especially considering that these days longevity of battery decides the lifespan of the device.

In order to take better care of the batteries in your device and to extend the lifespan, you should learn these mistakes you regularly make while handling them:

Why Lithium-ion battery

A lithium-ion battery is an advanced battery technology that uses lithium ions as a key component of its electrochemistry.
From the smartphone in your pocket to the Tesla on road, all are powered by Lithium -ion technology. Lithium- ion batteries have many advantages over other technologies as they charge faster and have a better longevity.

How Lithium-ion battery works

Every battery has three main components: a positive electrode called cathode, negative electrode called anode and an electrolyte in between through which ions flows from one electrode to another. In the case of most Lithium-ion batteries, Lithium Cobalt Oxide is used as Cathode and while Graphite is used as the anode.

When charging, the Lithium atoms to move towards the anode. While discharging lithium atoms in the anode are ionized and separated from their electrons, these electrons flow through the circuit to cathode creating the electric current. The lithium ions move from the anode and pass through the electrolyte until they reach the cathode, where they recombine with their electrons and electrically neutralize, explains Clean Energy Institute, University of Washington . This process is repeated whenever the battery undergoes charging and discharging.

Mistake No: 1 -Exposing the battery to heat

Heat does bad things to lithium-ion batteries. A Study by Feng Leng, Cher Ming Tan and Michael Pecht published in Nature states that temperature is known to have a significant impact on the performance, safety, and cycle lifetime of lithium-ion batteries. This is true, as the phone battery gets warm, the chemical reaction inside the battery gets faster, which can even lead to the breakdown of the electrolytes

According to Apple, the batteries are designed to perform with temperatures of 16° to 22° C, which they term as the ideal comfort zone. Exposing your device to temperatures higher than 35° C can permanently damage battery capacity.

Mistake No: 2 - Waiting for the battery to die before charging

When you burn through 100% of battery capacity, it completes one battery cycle. Every battery has a limited number of charge cycles, between 500 and 1,500, denoting the lifespan of the battery. However, we always wait for our device's battery to die before charging them, which doesn't do any benefit to the lifespan of the battery.

Apple explains one way to extend the longevity of the battery is to charge them whenever you feel the battery capacity is low:

"You complete one charge cycle when you've used an amount that equals 100% of your battery's capacity — but not necessarily all from one charge. For instance, you might use 75% of your battery's capacity one day, then recharge it fully overnight. If you use 25% the next day, you will have discharged a total of 100%, and the two days will add up to one charge cycle. Thus, it could take several days to complete a cycle."

Mistake No: 3- Storing devices improperly

If you feel that the right way to store is by exhausting your laptop's battery capacity completely or by keeping the battery full, you are mistaken. Rather, store the device half- charged. If you store a device when its battery is fully discharged, the battery could fall into a deep discharge state, which renders it incapable of holding a charge. If you store it fully charged for an extended period of time, the battery may lose some capacity, leading to shorter battery life, points Apple's guide on battery performance .

Additionally, store the device in a cool, moisture-free environment, as storing a battery in a hot environment can damage it irreversibly. If you plan to store your device for longer than six months, charge it to 50% every six months.
