10 Best Ways To Preserve Your Phone Battery Lifespan

Now You Know

Nowadays, a lot of people have become more connected than ever. Smartphones indeed come in very handy in keeping us updated and connected with the rest of the world. However, a phone’s battery life is just as important as the phone itself. Regardless of your phone’s capabilities, it’ll all be rendered inefficient unless your phone battery can keep up with you throughout the day. Notably, while most smartphone users invest more in reliable covers or casing, they often neglect to protect their phone’s battery.

If you’re thinking of preserving and prolonging your phone’s battery life, there are many relevant things you must know. That said, we highlight all of the vital information to help extend your phone’s battery life.


Understanding The Component Of A Phone Battery

The most common battery found in smartphones is ‘lithium-ion batteries’. To provide you with a better understanding of a phone’s battery components, let’s first discuss how batteries work. Three elements are required for electricity to flow within batteries, keeping you charged for the day. 

The first element is the anode or the negative component of the battery. It’s labeled as the negative (-) sign in a battery. A chemical reaction from this component will build up positive ions and electrons. 

The next element is the cathode that doesn’t accumulate any elective or positive ions. It’s symbolized as the positive (+) sign on a battery. The negative charge will equalize the difference by passing through the cathode. 

 The last element we’ll discuss is the electrolyte. Basically, an electrolyte is an insulator that blocks negative charges while moving through it. It is placed between the anode and the cathode, blocking them from one another. As a result, electrons can’t pass through directly from the cathode to the anode.

If a conductor links between the anode and the cathode outside the battery, the negative charges will now have the alternative method to pass through from the cathode to the anode. As the negative charge passes through the conductor, the positive ions traverse through the other direction into the electrolyte and towards the cathode. The process in which electrons move through the conductor will generate electrical power, hence powering up any electrical device connected to the conductor.

Lithium-ion batteries are considered one of the lightest metal components that have excellent electrochemical capacity. Despite its weight, it contains the largest energy capacity. In terms of sustainability, lithium-ion batteries are more stable and safer compared to traditional batteries. They also have fewer impacts on the environment when disposed of.


What Is The Average Lifespan Of A Phone Battery?

The amount of lithium ions in the phone battery’s anode and cathode is reduced for every charge and discharge over a period of time. Hence, phone battery life eventually deteriorates once it has reached a specific number of charge and discharge cycle. In a nutshell, a phone’s battery lifespan is the number of charges and discharges a battery can handle before it loses its ultimate performance.

On the contrary, a phone’s battery life only measures the duration for a singular discharge. With Apple smartphones, the battery lifespan ranges between 300 to 500 charge cycles, approximating 1.5 to 2 years of normal performance. As a result, Apple devices’ battery life will begin deteriorating notably to approximately 80% levels with full charge capacity after 500 charges. It will also continue to decline to zero once more charges are depleted on the phone battery. 


What Is The Price Of A Phone Battery Replacement?

Before anything else, check if your smartphone is still under warranty. If you have an insurance policy, verify with the company if a phone battery replacement is available. The majority of smartphone manufacturers have standard one-year warranties for defective smartphone batteries. Mobile service providers such as AT&T and Verizon have insurance plans that won’t charge any amount for faulty smartphone batteries. AppleCare warranty also offers battery replacement for free.

If you’re already out of warranty or your insurance policy won’t cover battery replacement costs, phone battery replacement will cost between $10 to $100. Some battery replacements can go as high as $299, depending on your smartphone’s brand and model. The process takes approximately five to seven days from the date you surrendered your device for repair services.

Given the cost of a phone battery replacement, you should evaluate whether it’s worth the price or not. In most cases, new smartphones are already introduced in the market after two years. That said, instead of opting for a battery replacement, it’s much ideal to invest in a new device and sell your older smartphone for cash. However, if you indeed want to retain your smartphone’s previous performance, you must be prepared to cover the costs.

Specifically, cold temperatures don’t come on good terms with phone batteries. If you’re residing or have visited cold countries with freezing temperatures, you may have observed that your phone battery life isn’t durable enough. Due to a smartphone’s lithium-ion content, extreme temperatures usually compromises the phone battery’s performance. That said, extreme cold weather accelerates the battery’s resistance, resulting in a decrease in positive ions and electrons.

In addition, the chemical reactions are blocked or slowed down by freezing temperatures, thus resulting in poor battery output. According to Live Science, chemists don’t exactly know the reason why. Therefore, smartphone manufacturers can’t identify why the battery indicator isn’t accurate enough when subjected to extremely cold temperatures.


2. Conserve Battery Power
