How different types of battery work, their advantages and disadvantages, and how to take care of them.
The battery of a phone is a very vital component. In order to make sure your phone is working good after 1 year use, you need to take care of your battery. Let's take a look at the types of battery a phone uses.
Lithium-ion (Li-ion) - battery in which lithium ions move from the negative electrode to the positive electrode during discharge and back when charging.
#1 - They have no "memory effect", which means that you do not have to completely discharge them before recharge.
Fun fact - some people and stores will still tell you that it is better to fully discharge your li-ion battery before recharge, but this is not true. In fact, this will destroy your battery even faster!
#2 - They have hundreds of charge/discharge cycles.
#1 - They start degrading as soon as they're created. Whether you will use them or not, they will degrade, and after 2 or 3 years, they will not be efficient at holding a charge.
#2 - They are sensitive to high temperatures. They degrade much faster when in hot environment.
Tip - do not leave your phone on the car dashboard or on places to which sun has access.
#3 - Even though it is a small chance, if a li-ion battery fails, it will burst into flame.
Lithium Polymer (Li-Po) - battery which uses polymer electrolyte instead of a aqueous electrolyte.
#1 - Very lightweight and pliable, and can be made to almost any size or shape.
Fun fact - this is why most thin phones uses Li-Po battery - it can be made to any shape or size, so that the phone desing still remains thin.
#2 - They can be smacked, banged, punctured, dropped, even run by a car, and still not explode!
#3 - They have no "memory effect", just as Li-ion battery.
#1 - Overcharging or overheating of a Li-Po battery can result in a fire.
#2 - If a Li-Po battery is bulging, it should never be used or charged again.
#3 - Lesser cycle of charge/discharge compared to Li-ion battery.
#4 - Compared to Li-ion battery, price and energy is higher.
How to take care of your phone's battery:
Whether your battery is Li-ion or Li-Po, you need to observe some general rules. Keep your battery not too hot and not too cool. If you play games on your phone, most high graphical games will cause heat, which will make your phone battery discharge faster. It would be wise to close the game and let it cool. Do not mine cryptocurrency on your phone, as this is guaranteed to destroy your phone's battery in just a month or two.
Keep your battery level percent in the mid of 40% and 80%, as this is the most healthy. Do not let it discharge completely or overcharge it. Discharging Li-ion completely will destroy this type of battery, but do not be scared - your battery will not let you discharge it completely anyway. If you will not use your second smartphone (if you have, of course) for a long time, try to keep its battery close to 50% and do not let it drop to 20%. This way you will maintain your battery to healthy state.
"Memory effect" of a battery and useful information:
Memory effect is an effect which can be seen in nickel-cadmium and nickel-metal hydride batteries. This effect causes them to hold less charge. This is a situation in which nickel-cadmium batteries gradually lose their maximum energy capacity if they are repeatedly recharged after being only partially discharged. Older phones used one of this type of batteries, and this is from where the syndrome of "fully discharge your battery before recharging" comes. And it is true, but only for these phones. Newer phones use only Li-ion and Li-Po batteries, so you can recharge them as how you want.
Cycles of discharge/charge means that your battery can be discharged and then charged from 0% to 100% and this will cost only one cycle of the battery life. If you discharge and charge your battery from 50% to 100%, this is half cycle.
