There are approximately 80 types of batteries existing nowadays. However, we will discuss primarily lithium-ion batteries. Lithium-ion batteries power the majority of modern smartphones. 

Similar to traditional batteries, a lithium-ion battery contains three main components. It contains an anode, the battery’s negative part. The anode is usually indicated with the “–” sign on most batteries. With anode, a chemical reaction creates electrons and protons. The battery’s second component is known as cathode, often symbolized by the “+” on most batteries. The cathode doesn’t build up any form of charge. Through the cathode, a group of electrons will equalize the positive and negative charges within the battery.

Lastly, the third component is the electrolyte. It performs as an insulator that blocks electrons from passing through. Positioned between the anode and the cathode, electrons block them from each other. As a result, the electrons won’t pass through from the cathode to the anode, trapping themselves in their own zone.


Lithium-Ion Batteries

With the existence of conductors such as lightning cables or chargers, the anode and the cathode connect outside the battery. As a result, the electrons will now have the opportunity to pass through the cathode from the anode. As the electrons pass through the conductor, the positive charges move to the other direction into the electrolyte towards the cathode. The process of passing through the conductor by electrons provides power to any electrical gadget connected to the conductor, thus producing an electrical charge. To complete the process, the electrons will move back into the cathode and rejoin with the protons.

The difference with lithium-ion batteries from other types of batteries is the chemicals used within the three components. With different chemicals, different kinds of chemical reactions are produced at different rates of positive charges and electrons. That said, it offers various levels of sustenance, voltage, and battery capacity. The majority of smartphone manufacturers generally use batteries with lithium-ion components. It is primarily because of lithium’s lightweight characteristics.

Besides, it also contains a significant amount of electrochemical charge. Despite its weight, lithium battery contains the largest energy density. While it may have issues here and there, the lithium-ion batteries are considered more stable and safer compared to other batteries. In terms of environmental advocacy, lithium-ion batteries have less environmental impact compared to traditional ones.

If you frequently use mobile apps that drain a lot of battery and use a lot of data, you are depleting your smartphone’s battery more quickly. If you want to conserve your smartphone’s battery, you should avoid playing mobile games for long hours, read news articles instead of streaming on YouTube, and become mindful of what you’ll be accessing on your smartphones.


4. Frequent Use of Battery-Draining Apps and Activities

With everything in life, all should be done in moderation, including your smartphone’s location-tracking services. If you’re constantly checking the weather or using Waze and Google Maps when you’re traveling, you’re giving these apps the access to track your current location. Hence, it uses a lot of battery charge. It’s definitely OK to use apps that utilize your smartphone’s GPS-tracking feature; however, it should be done in moderation.

It also applies to streaming videos and music all day, frequent tethering (mobile hotspot) of devices, and playing a lot of mobile games. If you want to avoid your phone battery draining so fast, maybe it’s time to check on your phone habits and eliminate activities that contribute to depleting your smartphone’s battery so quickly.

The lifespan of batteries is dependent on numerous factors; therefore, there’s no fixed answer to this question. However, lithium-ion powered smartphones nowadays generally have a lifespan between two to three years. It translates to 300 to 500 full charge cycles. Once it has reached a minimum of 500 recharging cycles, the battery capacity will deteriorate to 80%. So, if you’ve reached more or less 2,500 full charge cycles, your smartphone’s battery will no longer work efficiently.

Let’s say in the case for Apple smartphones, the batteries are estimated to have a minimum of 500 full charge cycles before they deteriorate to 80%. To give you a better perspective, there’s a noticeable change in an iPhone’s battery performance after:

  • 8 months – 2x daily recharging
  • 16 months – 1x daily recharging
  • 32 months – 1x recharging every two days


Phone Batteries in A Nutshell

The frequency of charging your smartphones is directly proportional to the smartphone’s battery life. Another thing that you should avoid is draining your phone’s battery to the lowest level or 0. Unlike traditional nickel batteries, lithium-ion batteries will deteriorate by:

  • Extreme battery charge;
  • The amount of battery juices consumed before recharging

Therefore, the deeper you deplete your phone, the more stressful it is for the phone’s battery. That said, if you are going to completely discharge your phone, draining it down to 0 is the most stressful; hence, the easier it is to deplete your battery lifespan.


Now, that’s a wrap. We’ve highlighted everything you need to know regarding why your phone battery is draining fast and the possible remedies. After all, caring for your smartphones is one of the best options to preserve its battery life, and of course, save money in the long run.
