Before we dive into the debate, it’s essential to understand how smartphone batteries work. Most modern smartphones use Lithium-Ion (Li-ion) batteries, which are known for their high energy density, long cycle life, and relatively low self-discharge rate. Li-ion batteries consist of three main components: a positive cathode, a negative anode, and an electrolyte that facilitates the flow of ions between the two electrodes.
How Li-ion Batteries Degrade
Li-ion batteries degrade over time due to a combination of factors, including charge cycles, depth of discharge, temperature, and age. A charge cycle is completed when the battery is discharged from 100% to 0% and then recharged back to 100%. Most smartphone batteries can handle around 300-500 charge cycles before their capacity starts to degrade significantly. Depth of discharge refers to the extent to which the battery is drained before recharging. While it’s not necessary to drain your battery to zero on a daily basis, avoiding extremely shallow discharge cycles (e.g., always keeping your phone between 80% and 100% charged) can help prolong its lifespan.
The Role of Calibration
Some smartphone users believe that draining their battery to zero once a month helps to “calibrate” the battery, ensuring that the phone’s battery gauge is accurate. However, this is a misconception. Battery calibration is not necessary for modern smartphones, as they use sophisticated algorithms to estimate battery capacity and state of charge. In fact, repeatedly draining your battery to zero can cause more harm than good, as we’ll discuss later.

What is the myth about draining phone batteries?
The myth about draining phone batteries originated from older battery technologies, such as nickel-based batteries, which had a “memory effect.” This meant that if these batteries were not fully discharged before recharging, they would “forget” their full capacity and eventually lose their ability to hold a charge. As a result, it was recommended to fully discharge these batteries once a month to maintain their health and capacity. However, this advice was based on outdated technology and does not apply to modern smartphones, which use lithium-ion batteries.
Lithium-ion batteries, on the other hand, do not have a memory effect and can be charged and discharged without affecting their overall capacity. In fact, fully discharging lithium-ion batteries can actually cause more harm than good, as it can lead to a reduction in their lifespan. This is because deep discharges can cause stress to the battery cells, leading to a decrease in their overall capacity and potentially causing them to degrade faster. Therefore, it is not necessary to fully discharge your phone’s battery once a month, and you can charge it as needed without worrying about affecting its health.
Will draining my phone battery once a month improve its performance?
Draining your phone battery once a month will not improve its performance. In fact, it can actually have the opposite effect. Deep discharges can cause stress to the battery cells, leading to a decrease in their overall capacity and potentially causing them to degrade faster. This can result in a reduction in your phone’s overall performance, as the battery will not be able to hold a charge as well as it used to.
