Everything you need to know about cell phone batteries

One of the most used batteries in the world which many of us don’t even know much about is our cell phone batteries. Many questions come to mind when dealing with a cell phone battery and to answer all those, you need to know a little about the batteries themselves. Most of our cell phones batteries are made up of lithium ions. The reason lithium ion is most commonly used is because it is light and can pack a lot of energy by itself.

The lithium ions are broken down into two more parts consisting of electrodes and electrolytes. The lithium in the batteries are very reactive, so cell phones contain a safe form of it called lithium cobalt oxide. These molecules pull electrons towards themselves when the battery is being charged and when the phone is being used, the power is provided by the release of these electrons.

Battery capacity

A battery’s capacity is highly dependent on its use. If the cell phone is being used more often and has many other processes running, it will discharge quicker. Hence, it is advised to take caution with your battery to ensure it lasts longer.

A good way to keep a tab on your battery’s life is by installing an application that allows you to keep an eye on the life of your battery.

Controlling the power

Keeping a check over your cell phone’s battery is very important. This is because the lithium that is contained inside is very reactive. If it gets too heated, it could cause some serious damage to your cell phone and maybe even to you. Cell phones consist of a small technology inside that allows the phone to charge to its complete ability and then puts a stop to power. However, if you feel that your phone is losing the ability to do so (you can tell if the phone starts to get warm every time you charge it), you will need to take it off charge as soon as it is complete.

Frequently asked questions

Will overcharging the battery cause damage?

When the environment around the battery is hot or it starts to warm up from the heat of the power, the lithium ions start to deteriorate. This causes the battery to lose some of its charging capabilities. Otherwise, the modern smartphones come with a technology that allows them to only absorb as much power as required. This statement could not be held true for older phones that do not possess the ability to recognize when the battery has been fully charged.

Do batteries lose their capacity with time?

Batteries do tend to lose their capacity over time. Cell phone battery operates in cycles, and one cycle is equal to one full discharge. A battery has the capacity to withstand 300 to 500 cycles and after that, it will start to lose its battery capacity which, in turn, leads to it losing its life. It is possible for you to save the cycle by not letting your battery completely discharge in one go.

How can you save your cell phone battery?

You can save your cell phone’s battery through many ways. Some will even help make your battery life stronger.

  1. Close all processes that are not being used
  2. Turn off the location and weather apps
  3. Turn off the push notifications
  4. Add a battery optimizer to your cell phone
  5. Lower your screen’s brightness

Should the phone battery be recharged once it has been used above 75%?

For lithium-ion batteries, it is not feasible to charge for a long period of time as it only uses up their charging cycles. It is better to recharge your phone when it has been partially discharged; around a 50% discharge would do just fine. It would prolong the battery’s life, making it more efficient.

Will turning off the Wi-Fi save the battery life?

Keeping other processes running is more likely to deteriorate your battery life than keeping Wi-Fi and Bluetooth on. They do not require as much power as they used to before, but turning them off would at some small level help save your battery. 3G and 4G will drain your battery life much faster than Wi-Fi and so does a cell phone searching for a radio signal. Hence, turning on the airplane mode will probably save your battery.

Should you charge your phone when you first get it?

Before smartphones were common, cell phone batteries used to contain nickel cadmium. It was due to this that batteries were highly dependent on how they were charged; the use of the battery and how you took care of them also mattered a lot. But with smartphones came the modern lithium-ion batteries, which do not require too much care. You can use them straight out of the box until you feel the need to charge them.

Reconditioning

It is not a well-known fact, but cell phone batteries can be reconditioned as well. The way to recondition them is fairly simple. You will start by discharging your batteries completely. Once that is done, turn your phone back on and let it turn off itself. Once that has been done, recharge your phone completely and let if charge more for a few hours. After that, you need to repeat the steps at least 3 more times. The battery will be reconditioned and will regain most of its capacity.

What the future holds

Many scientists have started looking for an alternative to lithium-ion batteries with the main aim of them being able to provide a longer battery life, longer usage time, and an overall more efficient battery. Some have now discovered supercapacitors, which have the ability to perform much better than lithium-ion batteries. There is still a lot of research to be done regarding alternative battery types and only the future will tell what we are in store for.
