What is the Relationship between Mobile Phone Charging and Mobile Phone Battery?

Most smartphones today run on lithium-ion batteries, which work in charge cycles. A brand-new lithium-ion battery can last between 300 and 500 charge cycles. This is where your cell phone charging habits come into play. Generally, a smartphone’s battery can last between two and three years, but the frequency with which you charge it significantly affects how quickly you run through those charge cycles.

To clarify, lithium-ion batteries, regardless of your charging habits, will deteriorate even when sitting on a shelf. Irreversible internal structure changes happen as you cycle the battery.

As a result, the lithium count gradually drops and gets lodged onto the anode during normal usage. It forms a restrictive layer that increases the battery’s internal resistance, ultimately lowering its capacity.

In terms of your cell phone charging habits, the following factors speed up the growth of the restrictive layer:

  • Low battery level
  • Deeper discharge
  • High discharge rate

Effect of Partial Charging on Your Phone’s Battery

Operating your phone’s battery at a low voltage can increase the number of available charging cycles before you see a significant reduction in its capacity. According to Battery University, every 0.1V decrease in cell voltage can double the cycle life.

That means charging your smartphone in that 30% to 80% range can keep the voltage lower and prolong the battery’s lifespan.

Power banks are great as they allow you to charge your smartphones anywhere. These handy gadgets come in different sizes and shapes but are small enough to fit in your pocket. Whether you’re traveling or running errands, a power bank can be a great help.

But make sure to use a power bank with optimal voltage and current level. If the voltage and current levels are too high, it can damage the battery’s health.

What is the Best Way to Charge your Phone for the First Time?

When you buy a new mobile phone, its battery is never 100% charged, irrespective of the brand. So, if you’re charging your phone for the first time, never charge 100% for some time. After a few weeks, you can charge it fully once or twice a month. Also, it is advisable to remove the charger of your new phone when it is 90% charged. It will not overload the battery and improve its capacity and longevity.

So, when should you charge your new mobile phone? You should charge it before 20% less. This is because lithium-ion batteries may lose their capacity when the charging is less than 20%.

To maintain the optimal performance of your new phone’s battery, make sure to pay attention to the following points:

● Use Original Charge

When charging your phone for the first time, make sure to use the original charger and USB that comes with the smartphone. If the original charger gets damaged, buy a new one from the same manufacturer/brand.

● Read the User Manual About Charging

A user guide about battery and charging comes with new cell phones. Make sure to read this guide thoroughly and follow the instructions to protect your phone’s battery life.

● Avoid Charging Again and Again

Aim to charge your mobile battery only once a day if not necessary. Otherwise, it will put a load on the battery and reduce its capacity.

● Use the Right Charging Method

Use the standard wired charging method to charge your phone for the first time. Innovative approaches, such as power banks and wireless charging, are convenient but can damage your new phone’s battery.

What’s the Best Way to Charge Your Phone’s Battery?
