Why Is There a Belief That You Should Drain Your iPhone Battery?
The belief that you should drain your iPhone battery before recharging stems from older battery technologies. However, this practice is not necessary for modern lithium-ion batteries, which power most smartphones, including iPhones.
According to Apple, a reputable technology company, lithium-ion batteries do not suffer from “battery memory” issues, which were common in earlier nickel-cadmium batteries. This means you do not need to completely discharge the battery for optimal performance.
The underlying reason for the antiquated belief relates to the chemistry of older battery types. Nickel-cadmium batteries would develop a memory effect, where a battery that is repeatedly recharged before being fully discharged would “remember” its last charge level. This led to reduced capacity over time. In contrast, lithium-ion batteries do not have this problem because their chemical composition allows for efficient charging at any charge level.
Lithium-ion batteries operate through a mechanism that involves the movement of lithium ions between the anode and cathode during discharge and charge cycles. When these batteries are partially charged, they do not degrade significantly. Avoiding complete discharges can actually prolong their lifespan because deep discharges can stress the battery chemistry.
Specific conditions that can contribute to battery degradation include prolonged exposure to high temperatures and allowing the battery to remain in a deeply discharged state for too long. For example, leaving your iPhone fully discharged for an extended period may lead to a state of battery calibration loss, which may require recalibration for consistent performance.
In summary, the belief that you should drain your iPhone battery is based on outdated information. Modern lithium-ion batteries benefit from regular charging without needing a full discharge, and maintaining them within a range of 20% to 80% charge can help maximize their lifespan and performance.
