Why Does the Phone Battery Deteriorate Over Time?


You buy a new phone, and the phone battery looks suitable for a while. Take your phone in the morning, spend the day at work, and have enough shipping left to go home. But what if we go a year into the future! Everything will change.

Now you can see the battery indicator falling if you haven’t weakened the screen’s brightness with a flimsy attempt to keep your music alive until you set foot on your doorstep. Inevitably, something has changed.

Why Does Phone Battery Deteriorate So Fast?

But this is the general situation. We’re interested in your battery. But to determine why it no longer works as it used to be?

Like most mobile electronic devices, smartphones use li-ion rechargeable batteries because they are lighter and more efficient than other batteries.

These batteries transport lithium ions between two electrodes: a negative pole of lithium oxide and cobalt and a positive carbon pole (graphite).

When you charge the battery, the ions gather on the positive pole, and when the charge empties (when used), the ions return to their negative electrode.

This process is called recycling and is a compatible part of the design of these batteries.

How often you charge will affect the battery life?

The more regularly you top up your battery, the better. To minimize battery degradation, top up for every 10% drop in battery level. And keep your battery level as close to the mid (50%) as possible. Impractical and impractical, yes, they are. But these are only for making the most of battery health. There is much room for tweaking to add more convenience to the mix.

Recycling the Phone Battery

If the recycling process is 100% return, the android or iPhone phone battery can’t perform worse. But as I expected, that’s not going to happen.

Whenever you charge your battery, a thin layer of lithium atoms remains united with the positive electrode, reducing battery capacity.

If ions can no longer move, they cannot move their charge and therefore cannot deliver power. And the next time you ship it. You can say goodbye to another layer of lithium atoms.

When repeated hundreds of times, you’ll see a marked drop in the amount of power the battery stores.

A thick and increasing layer of immobile lithium (in the form of lithium oxide and lithium carbonate) collects on the positive pole, obstructing interaction with graphite.
But this isn’t the whole story.

Ineffective Battery Rotation

Ineffective battery rotation causes a steady but gradual decrease in battery capacity. As with a positive pole that soon becomes covered with a layer of material due to the recharge process, the negative pole also develops a coating similar to that formed on the lively bar due to electrolyte oxidation.

The hotter the battery (or the higher its voltage), the faster and more damage this reaction will be. The reaction capabilities of the negative pole are immediately disabled, causing sudden and irreversible loss of battery capacity.


The above result is that the lithium-ion reaction used to deliver energy can no longer be done to the fullest. The phone battery, in turn, is no longer able to retain or provide the amount of energy it used to deliver when it was new.

Mainly, your phone’s battery stops working because the electrodes have rusted. The primary thing you have to do is not expose the battery to high temperatures. Increased battery temperature above 35°c causes negative pole performance to decline significantly.

Also, battery capacity fades at low grades, but this (usually) is a real-time effect. So you have to keep the battery at a temperature of 16-22°c for optimal performance.

It can mean removing any cover from the phone during the charging process and sometimes separating the phone from charging if its temperature becomes too high. Speaking of shipping, this is another tip: don’t charge the phone battery up to 100%.

It may seem counterintuitive, but your battery will work more with a partial charge if you don’t need a full battery. High heat hurts the battery by raising the voltage, and when charging the 100% y battery, you’ve also increased the voltage.


Batteries must retain some power to keep their internal protection circuits effective, and allowing them to unload their entire charge (Deep Discharge) will destroy their ability to keep charging permanently.
During daily use, lithium-ion batteries prevent this by claiming that they are empty while still retaining some power but will fail if left to unload more.

If you want to store a tool for a long time without use. You should ship it for about 50%. It keeps the voltage low (protecting the negative pole) while retaining enough cards to keep the firewalls effective for several months.
