Smart Phone Batteries – Introduction, Life Cycle And Cost

Dec 03, 2020   Pageview:50

The main thing that we always consider when buying a smartphone is the battery capacity, battery type, battery's design, and the amount of time required to charge the battery. Smart Phones have a lot of programs; thus, the amount of energy consumption is high.

If you own a smartphone with a small battery, you will spend a lot of time charging the battery. You might even charge a battery twice a day. Therefore, phone manufacturers are working day and night to increase the efficiency of their batteries.

I remember I had a smartphone that used to drain the battery after a few hours. I could not go on long trips with the phone because I had a fear of being stuck. I had to buy a power bank to support the battery. This issue faces so many people nowadays.

Therefore, we need to consider the various battery types that are used in smartphones. It is also good to know the efficiency, durability, and reliability of these batteries. Therefore, follow me through and get the best out of this session.

What kind of batteries do smartphone batteries use?

The smartphone industry has been advancing over the years. We started with low capacity batteries, and now the battery capacities are increasing every day. We started with removable batteries, and now all the manufacturers are moving towards built-in batteries.

Therefore, the batteries that smartphones need depend on the power consumption of that particular phone type. Some smartphones have very powerful programs that need a lot of power; thus, manufacturers try as much as possible to make their batteries powerful.

The most common batteries in terms of chemical composition used in modern smartphones are Lithium Polymer and Lithium-ion batteries. Lithium Polymer is the most recent and most advanced technology for smartphone batteries.

Therefore, let us consider these two batteries in detail. We need to know how efficient they are in charging time, durability, and their differences.

Lithium-ion (Li-ion) batteries

Most manufacturers prefer lithium batteries because they are light and provide an extended battery life. This battery type has its light and compact design as its strength for the smartphone industry.

The only thing that is a disadvantage of this battery is the limited number of charges. This battery can undergo between 300 and 1000 charge cycles, which is less than the old nickel batteries. The production of lithium \-ion batteries is a bit expensive.

They are also dangerous because they can overheat and lead to a fatal explosion because the materials used in making it are flammable. You need always to leave some charge of at least 40 percent on these batteries and avoid charging them for long hours.

Charging lithium-ion batteries is much faster than charging any other battery type. The battery charges in two phases; it quickly charges up to 80 percent, and then it slowly charges to reach 100 percent.

Lithium-Polymer batteries (LiPo)

LiPo batteries are becoming more popular and more common now. They are similar to lithium-ion batteries, but they are more flexible to be used in smaller devices. They are also lighter and have more energy density.

However, LiPo batteries are more expensive than lithium-ion batteries. They are also more flammable; thus, they pose a significant risk when they overheat or are exposed to fire.

Another major disadvantage of this battery is that it will be hard to charge it again with standard charges if the phone is left without a charge. Therefore, you must be careful not to drain the battery fully before charging it.


How many years does a smartphone battery last?

The number of years that a battery will last will depend on several factors. One of the factors that play a crucial role in the battery's lifespan is its maintenance. If you maintain your battery well, then it can last for an extended period.

However, you need to know that batteries degrade with time, and you cannot avoid the decrease in capacity over time. The best thing to do is charge your battery with a standard charger and avoid unplugging your phone before it achieves full charge.

A smartphone battery can last for 2 to 3 years, depending on how you use it. This period can take between 300 and 1000 full charge cycles. The most efficient way of getting the maximum number of years is avoiding charging your phone under extreme temperatures.

Keeping your phone battery in moderate temperatures as much as possible will extend its lifespan. The frequency of charging your battery also affects the durability of the battery. The more you charge your battery, the higher the possibilities of extending its life.

How much does a smartphone battery cost?

This is the most critical part of every smartphone user. The amount that you will pay for a battery varies from one battery type to the other. It also depends on the battery's design; removable or built-in battery.

Thus, lithium-ion batteries are cheaper than lithium-polymer batteries when it comes to the type of batteries. The main thing that makes lithium-ion batteries much cheaper is that their production cost is slightly lower than that of lithium polymer batteries.

Generally, smartphone batteries cost between and $ 50, depending on the battery type you need. The built-in batteries are much expensive than the removable batteries because their design is a bit technical.

However, the best thing to do is taking good care of your battery to ensure it last for an extended period. You should never use a charger that the manufacturer is not recommended because it can damage your battery.


Smartphones now play a crucial role in our day-to-day activities, and it will be hard to live without it. I once tried to abstain from using my phone for at least a day, but I could not complete six hours. We need it more; thus, we must know how to maintain and take care of the battery.

It is costly to replace a battery, and there is nothing horrible like using a battery that dies after a few hours. It will not give you time to do your work. You will spend a lot of time charging the phone, translating to too many missed calls.
